Biochemical Maniac Urban Tour

114 Farewell Eve

There are two roads in front of Liu Xiao's eyes. One is to the scene of the massacre. As long as he takes a step, things can be solved perfectly.

The other way is to another unknown place, but Liu Xiao believes that as long as he gets there, he can only watch the tragic massacre continue.

Liu Xiao did not hesitate to buy the shooting scene and turned the fierce murderers over in an instant. Then the scene changed and appeared on the hall again. The only difference was that he took a step forward.

Can you tell me why you did this? I have clearly told you the duty of being an observer, but why do you still do such a superfluous thing? The voice was very confused and seemed to be looking for an answer.

Liu Xiao no longer tangled with the identity of the other party. He sat on the ground and said, "This has nothing to do with the observer. It's just what I want to do.

You're right. Maybe the power of the observer is powerful, and every small action may lead to destruction.

But the problem is that if I choose, I can completely share a small part of my own strength to save others.

If as an observer, I can only watch this kind of inhumane thing happen, then I would rather not be this laborious observer.

The voice was very gratified and said loudly, "Yes, it took me countless years to come to this out.

Stick to your heart and don't let your heart be lost.

Then answer me a question and you can go to the next level.

If there was a war between the two planets, which one would you help?

Liu Xiao thought for a moment and said, "No one will help. Just like the four holy beasts and dragons, the observer should also be a deterrent, a deterrent to those who break the rules.

So, as long as the rules are made, I will never care about the war within the rules of the game.

This is Liu Xiao's real idea, because through a series of things that have happened over the years, he can be sure that as long as the world wants to make progress, wars will inevitably continue to happen.

The voice did not say anything, but Liu Xiao found that he was in a sea of spirit at this time.

"This is the spiritual sea, which is condensed by the spiritual power left by many observers. You can choose to practice here and leave at the same time.

The gate is right in front of you. As long as you go straight, you can get out of here. The voice sounded again, and Liu Xiao also did not hesitate and left the spiritual sea.

It's not your own cultivation, and it's not your own after all.

When Liu Xiao recently communicated with Dr. T, his understanding of this point was quite thorough.

In particular, spiritual power cannot grow by absorbing the spiritual power of others. Although things that can absorb pure spiritual energy, such as Yuanying and Jindan, it is necessary to directly absorb spiritual power. Although it grows rapidly on the surface, it will actually be very troublesome.

Liu Xiao absorbed one or two spiritual bodies. Although he felt that the improvement was obvious at that time, the reaction after the event almost abolished his cultivation directly.

Fortunately, at that time, he was already a solid spiritual force and directly excluded these foreign spirits from his body before finally saved himself.

So, in the face of the endless spiritual power below, Liu Xiao did not miss it at a glance, and directly strode over and left this space.

Next, one test after another is basically a test of his heart and principles of life, and many of them still have a certain meaning.

I have to say that Liu Xiao has benefited from these tests.

"Very good. You are the first to come this far in countless years.

The earth is a very special existence. Only the human beings on it can become observers, so dragons and holy beasts often visit there.

It is called the cradle of observers, and as an observer, he will cultivate or choose a successor at the end.

However, it is a pity that since the disappearance of the earthlings of our generation, the earthlings of your generation are in a better condition as the boy surnamed Xuanyuan, but they have not passed these assessments.

Don't think that the so-called cultivation is something that doesn't care about the world. In fact, it can never be the strongest.

Among those monks who really fly into the four-dimensional world, most of what they follow are the principle of coming out and entering the world. Only by putting their hearts into the world and practicing can they maintain an invincible heart, can they be born and then go higher.

Unfortunate, there are too few people who know this. The voice was very emotional, but Liu Xiao thought that there was no difference whether he was born or entered the world.

"Ha ha, you are still too naive to withstand the strong heart of **. Not to mention the observer, even if he enters the four-dimensional space, there is no room for survival at all.

The cruelty there can never be imagined by outsiders. The voice is very vicissitudes, as if it reminds me of something I don't want to think of.

paused for a moment, and the voice continued, "Now that you have passed the test, take something and leave.

Ha ha, but when it comes to the test, this last thing is the real test. As long as you can pass it, then the position of this observer is yours.

Liu Xiao was very puzzled, frowned and asked, "Is it that simple? Forget it, let's not talk about that. Let's talk about you. Who are you? Why are you hiding your head and tail like this?

There was a moment of silence, and finally the voice said, "Well, just talk to you.

My name has been forgotten for a long time.

But you can call me manager, because I am your predecessor, and of course after you become a manager.

As for why I didn't appear, because I had died again in the battle with the Lord of the Void.

And the voice you heard is the last thought I left, but I believe it won't last long.

Lord of the Void? Liu Xiao had never heard of it, so he asked.

The voice is very lonely, but he said with a trace of remembrance: "The lord of the void is the king of the void world, and his strength is comparable to that of our observer.

The empty world is the place where biological desires and sins are carried. There, all sins and desires will turn into empty creatures, and the greatest obsession as empty creatures is to return to this world.

The Void Lord launched the first expedition to the Lord world hundreds of billions of years ago, and it was also that time that your so-called prehistoric humans, that is, our people, completely disappeared, together with the whole earth.

And the current earth was newly created by me with my spiritual power.

But this is not over. Just as the earth entered the dinosaur period, the second expedition of the Void Lord began, and I don't remember how long the war has been.

But one thing is certain that the extinction of dinosaurs at that time was caused by my degeneration with the Void Lord, and I have always felt very guilty about this.

But don't worry, the only channel between the main space and the empty world has been completely destroyed by me, and they will never come again.

"So that's it, but... Since there could be a tunnel before, can't there be a second one?" Liu Xiao is worried about this.

The observer sighed: "It's not as you think. The passage of the empty world existed from the beginning of the world.

Let's put it this way, I believe you should already know about the solid spiritual power forming the universe, but there is one thing you don't know.

The upper part of the diamond spirit body that forms the main time and space, while the lower part will form a void world, and the two worlds are like the two ends of the balance, forming an inherent balance.

Once someone breaks this balance, the whole world will be in danger of collapse, so when our time and space is formed, it is actually defective. Generally, there will be no channel, but we have appeared here, but Fortunately, we have made up for it.

Liu Xiao feels quite aggrieved. Why are you so unlucky? The universe where he was born is still a deformed child, with more pipes than people. Don't you think this is an extra move?

However, after thinking about it, Liu Xiao found another problem: "That's not right. Since part of it forms the main space-time, what's going on with the other parallel space-time?"

The observer laughed and said, "That's a mirror image of time and space, just like a mirage, but due to the distortion of space, there is a deviation between time and space.

The biggest difference is that this mirror image is completely real, not just a virtual shadow.

It's wonderful. Liu Xiao thinks that all this is really wonderful. At the same time, he can't help sighing the magic of nature.

The last assessment finally began. The only thing Liu Xiao had to do was to synchronize with the whole Golden Hall and synchronize his spiritual power.

The observer told him that the golden hall was cast with spiritual power. Of course, this was not for him to absorb, because the golden hall has been completely materialized and has become a material existence. If Liu Xiao really wants to absorb it, he can only completely decompose it again.

To be honest, this is the most difficult task encountered by Liu Xiao.

First of all, the spiritual power can't touch the Golden Hall at all, because once touched, you will find that the Golden Hall is absorbing these spiritual powers. It can be said that this is really terrible for Liu Xiao.

Of course, Liu Xiao also tried to feed the Golden Hall at first, trying to see what would happen to it once it was fed, but the problem was that even his strong spiritual strength felt tired, but the absorption speed of the Golden Hall was still the same and did not slow down at all.

It is precisely because of this that Liu Xiao dares not try like this.

"Old T, what do you think is going on?" After recovering his spiritual strength, he entered his spiritual sea, said his doubts, and asked at the same time.

Dr. T said confusedly, "I don't know, there are indeed many metals that can absorb spiritual power, but this is obviously not a known metal. The most important thing is that I feel that the characteristics of these metals are not absorption, but adsorption, and then they are passing synchronously.

If you seem to think so, then it makes perfect sense that we don't have enough mental strength.

Dr. T has reason to believe that if the observer is still alive, he will be surprised to see Liu Xiao's mental strength.

Because from the words of the two golden warriors at the entrance and the words of the observer, Dr. T is sure that even the observer is only at the level of solid mental power and has not reached the perverted strength of Liu Xiao today.

Therefore, judging by simple dosage, I'm afraid that four or five observers may not be able to catch up with a Liu Xiao.

It is because of this that Dr. T has this idea, and he also feels that this idea is correct.

Liu Xiao thought for a moment and felt that no matter whether this method was right or wrong, at least this was also a direction, so he asked, "So what should we do if it's really like what you said?"

The little Dr. T kept walking on the lotus platform. After a while, his eyes suddenly lit up and said, "Yes, how about we wrap the whole golden hall with our mental strength first and then forcibly inject it?"

To be honest, this method is tough and domineering, but Liu Xiao likes it.

Since he decided to do it, Liu Xiao sat on the ground and began to recover his mental strength.

On the earth, Nie Lan and others felt that their spiritual power was quickly taken away at the same time. Obviously, Liu Xiao's mental power was consumed very quickly.

Therefore, Nie Lan and others immediately put down their work and sat together, also trying their best to recover their spirits.

Because the spiritual power of these women is completely synchronized with Liu Xiao, they can have a spiritual resonance here, which can accelerate recovery more quickly as the number of people increases.

For example, Liu Xiao's six women are sitting together now, and their recovery speed at this time is exactly six times that of recovery alone.

At this time, in the palace, a mist rose around Liu Xiao, and a small whirlpool formed around him, constantly injecting spiritual power into his body.

After more than three hours, Liu Xiao's spiritual power finally returned to its peak state, and he immediately exerted his spiritual power and slowly and carefully wrapped the whole hall.

To be honest, Liu Xiao did this step carefully, and it doesn't work. Once the spiritual power touches the hall, it will be immediately "absorbed" by the hall, so that he must be re-covered for a while, which is time-consuming and laborious.

When he wrapped all the halls, he carefully put his whole spiritual power on the palace again.

This time, the palace is still absorbing spiritual power, but different situations appear five minutes later.

The spiritual power seems to be full and cannot be injected at all, but Liu Xiao clearly feels that the spiritual power is not injected into the palace itself, but is completely stored in the empty place in the palace. As Dr. T said, it is not absorbed at all, but In transmission, and at this moment, I can't continue to conduct, so this is the time for him to really start injecting spiritual power.

Strong spiritual power, like in a high-strength compressor, began to be constantly injected into the palace.

The golden palace itself is made of spiritual power, so its fusion of spiritual power can be said to be the strongest.

But the problem also arises here, because it itself is the condensation of spiritual power, so it can be said that it is more difficult to inject spiritual power.

Even the previous generation of observers do not know that in this case, if spiritual power is injected, then even if Liu Xiao method is adopted, the spiritual power of this person must be several times that of the person who condenses this spiritual power.

Fortunately, as Dr. T guessed, the standard of observers is solid mental strength and a stable mentality. However, no one can imagine that there will be a madman like Dr. T in the world, thus creating a super monster like Liu Xiao.

At this time, the golden palace began to shine with a faint golden light under the continuous injection of spiritual power.

The two golden warriors guarding the door released two golden lights in their eyes and collided with each other, but there was no explosion. Instead, they flowed into each other's eyes like exchanging information. The golden light rotated in their eyes and then disappeared.

Liu Xiao doesn't know that these two golden warriors themselves are the core of the golden palace. Who would have thought of guarding the door with the core?

It is the situation just now, like the exchange of information, which completely exchanges the spiritual information stored with each other, and it is the process of this exchange that erases all the previous information, which means that from this moment on, this golden palace has belonged to Liu Li.

However, it is a pity that Liu Xiao himself did not know this at this time, and at this time, due to the erasure of information, the idea of the previous observer also disappeared, so he was still constantly inputting spiritual power.

"Hum..."

The whole palace began to vibrate and emit an unprecedented light, which was the clearest in the United States at night. The brightness of the whole moon was very dazzling. Most importantly, it was a golden light that dyed the whole sky golden.

"What's going on?" President Rom was startled from the warm quilt, and his first reaction was that the Tals began to attack.

But what happened made him feel at ease a lot.

Because what happened here is too obvious, the women in the villa naturally feel the same as the moon, but not what they see, but purely the ** perception of spiritual power.

Knowing this matter, they were thinking about Liu Xiao's crazy mental recovery just now, so Huo Qingqing told Niu Ren about this matter as a policeman.

After hearing these words, Niu Ren was immediately relieved.

To be honest, the Chinese people don't feel anything, but the official astronomical observatory is scared by this scene.

The moon is golden, which is fine, but the whole moon shines like gold, which is a big problem. This has never happened before. Therefore, after their report, the first reaction of Chairman Gu and others is very similar to that of President Roma. They misunderstood this matter at the first time. Thal people are related.

Tal people are authentic alien invaders. Although these presidents look like nothing, in fact, they are also worried in their hearts. Who knows what will happen to the world next?

However, after receiving Niu Ren's phone call, Chairman Gu was relieved and immediately thought of the scene on the other side of the earth, so he couldn't sleep. He quickly met with the leaders of various countries through a video conference and briefly talked about the situation.

is simple enough, because he doesn't know what Liu Xiao went to the moon, and he doesn't know how he went there.

So in a word, the situation of the moon was created by Liu Xiao.

But this sentence is enough.

All the countries that were tossed around by this were relieved, but at the same time they were worried.

How powerful is it to make such a big move?

President Roma also found the superpowers and asked about their feelings.

The strongest superman shook his head helplessly and said, "He is very powerful and does not belong to human beings at all. I guess he is the only one who can fight against him in this world."

After thinking about it, it seemed that it was not right, so I made a little joke and said, "Maybe his wives can deal with him. I heard that Chinese people are very afraid of their wives... They are called wives."

Superman is not sure. To be honest, he doesn't know much about Chinese culture, so he doesn't have enough confidence.

President Roma sighed, but then he was relieved.

The stubborn people in Congress, after knowing this situation, see how they are this time*.

To be honest, I didn't put forward*. All presidents have the most headaches. They have done thankless things on both sides. The most important thing that is done well is the credit of Congress. If they don't do well, that is their president's guilt. Anyway, in a word, the credit and hard work is not yours. Anyway, you can't get it in the end. Good.

Now that it's better, there are guys with more deterrent than nuclear weapons. This time, these old men dare not stab there, and it's time to let him breathe a sigh of relief.

Liu Xiao did not know what happened on the earth at this time. He was immersed in a spiritual resonance, which was wonderful and seemed to be a communication completely independent of matter.

He can feel that this palace is actually "living". It has its own independent ideas, independent meaning, and even independent activities, and his core is the golden armored warrior who blocked him before.

This palace can become smaller as it wishes, and it can retain its own independent space.

In other words, it is similar to the universe ring, but this one is more powerful and can hold living things.

Liu Xiao actually thought about it before. Later, he wanted to live on the earth with his women, because it was their hometown, but they wanted to find a paradise and then suggested a courtyard.

But now it's different. With the golden palace, he can completely turn it into a villa, and these two golden warriors exist as housekeepers.

The resonance of spiritual power gradually slowed down, and the light around it became dim.

"Hum..."

With the end of Liu Xiao's spiritual input, the huge palace began to float in the air and keep spinning. At the same time, it slowly shrank and knew the extent to shrink to the size of a nail cap, and then stopped.

Liu Xiao looked at the thin golden line at the top of the golden palace and couldn't help laughing.

"Haha, we picked up the treasure this time. This thing was definitely condensed through the new blood of countless people, perhaps the new blood of many generations of observers.

That's great. It's so convenient to have this thing. Dr. T sat on the lotus at this time, laughing.

Liu Xiao couldn't put it down and played for a while before she took advantage of the shrinking ground and returned to the earth.

"Husband, how's it going? Have you found any baby?" Although Huo Qingqing is already the mother of a child, the momentum of the wind and fire can't be changed.

"Yes, I made a lot of money this time for your husband." When Liu Xiao said this, his mouth almost didn't come behind his ears. From this point, these women knew that the harvest this time was not ordinary. After all, Liu Xiao himself was not a person who saw money.

Then, Liu Xiao told the story about what had happened, especially about the empty world, which surprised a group of women.

When they heard that the former observer had destroyed the passage, they were relieved, but Nie Lan was still worried and asked the same question asked by Liu Xiao at that time.

Liu Xiao answered carefully, and then these women put their hanging hearts back into their stomachs.

It's not to blame them. You should know that Liu Xiao has spent a handful of time with them all year round. This is finally going to end. If there is another empty lord, won't this save their lives?

Liu Xiao secretly had a good time in his heart, but he couldn't say anything. He just took out the golden palace and put it in the courtyard of the villa.

According to Liu Xiao's idea, the small palace just grew up to the point where one person could enter and exit, and then stopped.

To be honest, according to the original appearance of the palace, even if only one person can enter and exit, the size is about the same size as his villa. Liu Xiao couldn't help shaking his head and saying, "It seems that if you have time in the future, you still need to adjust it."

"Wow, it's amazing here. It's amazing to see the whole starry sky as if you were in the universe." Ouyang Qing has never seen such a scene, especially after completely becoming a Liu Xiao woman, her personality began to change and become more and more cheerful, so when she sees beautiful things, she always shouts.

There has been a process of spiritual integration, and Liu Xiao certainly knows what's going on.

In fact, the palace itself is not as simple as it looks. The golden palace they saw is not its body, but just its entrance.

And its body is in a vast universe, and the position where they are is the most unique, and nothing can be approached, including the dragon.

Of course, if the owner of this space allows it to enter, they can still enter. Otherwise, wouldn't it be troublesome if they want to chat or something?

Six women took their children to turn left and right in the palace and found that the facilities here were too comprehensive. Although it was an ancient building, many of the designs were hidden with ultra-modern elements.

"Golden toilet, I used to see it in a cartoon, but I didn't expect someone to do it." Huo Qingqing patted the lid of the golden stool and said excitedly.

Liu Xiao said with a black face, "Please, that one is real gold. Ours is not an unknown metal condensed by spiritual power. The hardness of this thing is more than 100 times harder than diamonds."

"Cut, what's the use of being hard? It's not used for stool." Speaking of this, Huo Qingqing suddenly realized that they don't need to defecate at all. Why do they still need this to sit?

Liu smiled and said, "You don't know that. This thing is actually prepared for guests. Do you think the observer is really alone?

To tell you the truth, the previous observer also has many friends, and there are many ordinary people among them.

Of course, when these people come, the appearance here will change and become completely ordinary.

In this way, it will not disturb the development of the world.

Hearing this, the women knew that the life of the observer was not as monotonous as they thought. It was really great that they could invite friends to visit.

Everything was unexpectedly good, and Liu Xiao's mood relaxed, but he also said hello to the people of the country. From now on, he will not participate in anything again.

Of course, except for one thing, the Tal star master who came to the earth is tolerable.

Because it is clearly stipulated in an observer's regulation.

Each galaxy, or masters above the level of each race, are not allowed to enter other spheres of influence during the war, and can only take action at their discretion when there is a danger of annihilation.

Obviously, this guy crossed the boundary at the beginning.

Of course, although he has this idea, Liu Xiao will not do it now. After all, his strength is not so high.

The people in the country are actually very sorry, but they are also helpless, because Liu Xiao said that this is a rule that cannot be violated, which is also the best way for the earth and China.

Of course, as an authentic Chinese, Liu Xiao still sounded a wake-up call for the three leaders. Don't rely too much on the power of science and technology. Technology can assist human beings themselves, but developing those so-called mechanical technology and giving up physical strengthening is not the real way to become a powerful country.

The chairman seriously considered Liu Xiao's proposal, and in fact, they had done some similar things before, such as quietly changing the school's radio gymnastics to a set of skills to improve physical quality, but it seems that this set of skills is really more like gymnastics. Some.

Secondly, China began to vigorously rectify the food industry, which is also due to Liu Xiao's opinion.

Strong body is the key, but the problem is that you eat those toxic and harmful foods while strengthening the body, isn't it a disguised scourge?

Therefore, the country was cruel this time. A large number of food enterprises were sealed up one after another, and many leaders of food hygiene-related departments were arrested at the same time.

The people shouted for a moment, and the long-lost credibility began to gradually warm up.

The chairman and the prime minister looked at the recent report and couldn't help sighing loudly: "The demand of the people is too low, which makes us feel ashamed."

"A Xiao, are you really not going to continue to take care of it?" Nie Lan was a little puzzled, how to say that if she didn't care, she didn't care.

Liu Xiao hugged Nie Lan and said, "It's not that I don't care, but I'm almost in charge of it.

A country, or even a planet, can't rely on one person to develop. Although it seems to be prosperous, it is actually just a boost.

So, I have to let go now, and it's just right at this time. As long as they can eat through what I left behind and want to fight against the Tal people, although it can't be easy, they can also fight.

Yes, Liu Xiao gave the country some things, such as the research direction of new metals, and the most important, the development direction of biochemical technology, and some scientific and technological theories.

At this time, these scientific and technological theories are all in the research institute of T Energy. A group of biochemists from all over the world, as well as authorities in metal research, gathered here, and everyone has a relevant scientific idea or scientific vision.

"It's so great that it's unimaginable that someone can do this."

"Obviously, the theory of biochemistry far exceeds that of metal manufacturing, but later pointed out that in the future development, the two should be combined, which I don't quite understand."

To be honest, this idea is very bold, but it may not be impossible. I remember that it is recorded in some ancient books that some animals rely on metal to survive, and their feces will become something strange but still metal. Of course, we generally think that this is a fantasy, but if we look at it together, it may not be impossible.

You should know that imagination is the driving force of science.

"Very bold, really bold, but I reserve my opinion, because it requires scientific argumentation. You know, science is rigorous and not taken for granted."

"Let's not talk about this, look at this, this is definitely a century-making idea, and as far as I know, these have actually been applied to the army.

However, it is obvious that his idea is much stronger than those ice crystal blood worms and so on.

"Biological warships, which have been proven in the armies of the Tal people, but it is mentioned here that you should not blindly imitate the Tal people, but find ways to form your own unique and most suitable biochemical technology.

This is very pertinent, and it is also what we need to pay attention to most. Otherwise, if a copycat is not good and turns us into green brain shells, it will not pay off.

......

The discussion continues, and Mr. He is talking with Liu Xiao alone in an independent meeting room at this time.

"Xiao Liu, can't you really stay?" Mr. He is very reluctant to give up Liu Xiao. He knows that Liu Xiao's achievements in biochemical technology are far from what he can compare.

Liu Xiao knew that Mr. He was sincere, but since he had decided to change it, he said regretfully, "Mr. He, I can't stay any more. But you can rest assured that I have given you all the research directions.

Moreover, relying too much on me is actually very unfavorable for future development.

I have suggested to the chairman and the Prime Minister, and they have also agreed, saying that starting from this year, it will increase the training of talents in biochemical technology, which is of great benefit to biochemical scientific research.

"Well, in fact, to be from the bottom of my heart, it is difficult to make progress without changing the way of education.

I think you should also know that our country's education model has erased the imagination and creativity of students from the beginning. Although it has unexpected benefits in the early stage of social construction, the weakness in the development period and the disadvantages presented in the pioneering period are even more headaches. " Mr. He has never said this to anyone, and he also knows that this meeting is likely to be the last time, so he said something, even if he can't say it.

Liu smiled and nodded, but still smiled and said, "Don't worry, Mr. I believe the leaders will solve this matter.

Let's put it this way, for the needs of development, even if the leaders don't want to reform, they will be determined to actively reform.

Mr. He nodded. When he got to his current position, he naturally understood some things, but he always felt that he could not see this reform.

Liu Xiao also knows He Lao's regret, but he can't help it. As he and Nie Lan said, it develops too fast and sometimes it's not a good thing.

"Say, where are you going and what will your parents do?" Mr. He felt that the atmosphere was too dull, so he immediately changed the topic.

Liu smiled and said, "I won't leave Shencheng, but I just don't care about these things.

I think that after things on the earth stabilize, I will take Nie Lan and others on a world trip to see the wonders everywhere.

In the past few years, I've been too busy. I think I owe them a lot.

After thinking about it, he urgently said, "As for talking about my parents, I really have no idea for the time being. After all, I will be by their side for a long time."

He Lao nodded and understood the hidden meaning of Liu Xiao's words. His parents were there and they were not far away.

It seems that Liu Xiao wants to spend a good time with his family in the past few years. Thinking of this, Mr. He smiled instead: "That's right. Over the past few years, you have really paid too much, and it's time to have a good rest."

After saying that, Mr. He's topic changed again: "Who do you think will be the winner in the end of our war with the Tal Star?"

Liu Xiao hesitated for a moment, but finally decided to tell the truth: "There is no winner. Even if he loses, he will definitely come back.

And even if we earthlings can compare with each other in biochemical technology, some things have to be said that space technology is backward, which directly leads us not being able to reach Tal Star to fight.

So, this war will last for a long time, even tens of thousands of years.
