Chapter 4 Twenty years like 0.1 seconds

"A long time ago..." Li Weihan started to learn from his elders to tell stories.

Tang Xiuxiu raised her eyebrows: "It was 20 years ago, something for a long time."

Li Weihan's words were suppressed, and his little face turned red. The children laughed. Mr. Su quickly smiled and said, "Xiuxiu, it's not easy for other children to interrupt when telling stories. Let him finish telling them before correcting his mistakes."

"What's wrong, what's wrong!" Li Weihan's discontented quivering: "Did I say I want to start when the black hole appeared? I want to start with the big hero saving the old city in the beast tide. That must have happened almost 30 years ago."

"25 years ago" Tang Xiuxiu corrected Li Weihan again.

"No more, no more" Li Weihan was so angry that he refused to say anything.

Mr. Su hurriedly persuaded him, and the children around him also coaxed Li Weihan to tell a story. After a long time, he coaxed Li Weihan. He waved his little hand and said that the man would not fight with the woman, and then he talked about it again.

Although Li Weihan can't remember the year clearly, his eloquence is not bad. In addition, the identity of the people he usually contact with is relatively high. He hears much more about the past events in Bottlewind City than ordinary children, so this story is also very wonderful, and even Mr. Su is a little fascinated by it.

"... The great hero knew that the old man who played the sword would come to trouble in the old city sooner or later. What should he do? He sacrificed his life and dived into a big city in the northeast corner alone, went through a lot of hard work to get a powerful weapon, and then rushed here to trouble with the old sword-playing old man. He fought 300 rounds with the old man who played swords. The sky and the earth were dark, and he finally won, but his powerful weapon suddenly lost control and formed this black ball. This black ball is actually a black hole, and even the fastest light can't run out, so the big hero is also trapped in it.

Li Weihan said this, wiped his sweat and looked at the big black ball in awe.

"Wow, the big hero is really in it. Can he see us!"

"If you don't eat for 20 years, how hungry will the great hero be!"

"We have to find a way to release the big hero..."

The children began to discuss, and Mr. Su smiled. This scene is not uncommon for her. Almost every time the children finish the field observation class, they have to talk about this black ball. The topic is always inseparable from the legendary hero.

Mr. Su is a good teacher who is good at stimulating children's interest in learning. When she saw the heated discussion among the children, she asked, "Classmates, can you give you a topic related to big heroes?"

"Okay, okay!" The children shouted happily.

Mr. Zuo also put down the broken book in his hand and read it with interest.

"You have learned the basics of black holes in the second grade. Do you remember whether the world inside and outside the black hole is the same?"

As soon as Mr. Su finished speaking, the children answered in unison, but only Tang Xiuxiu answered in the most detailed way: "According to ancient scholars, the time in the black hole is static compared to our three-dimensional world, but according to Luo Bing's conjecture, there will be a time lapse relative to the outside world inside every black hole. Rate is called the T function, so the time in the black hole is also flowing, but it is much slower than the time lapse of the outside world.

Mr. Su touched Tang Xiuxiu's head: "Xiuxiu is right, because the only black hole we can study is the south black hole in front of us, so Luo Bing's conjecture cannot be called Luo Bing's theorem, but the T function of the south black hole has been calculated. This was originally yours. What I will learn next semester, I will tell you first today that the T function of the Xianan black hole is 1.685489. According to this function, can you calculate how long the big hero has been trapped in the Xianan black hole?

The children did not hesitate. As soon as Mr. Su's T function came out, they immediately began to operate the small black board in their hands. The black board stored all the courses from primary school to higher colleges. The study factor in their bodies stimulated them to have a strong thirst for knowledge. Many children quickly found black The hole time calculation formula is calculated quickly.

More than half of the children are mental arithmetic. The complex formula of more than ten digits involves multiplication and division. They actually don't use calculators. This is a group of genius children.

Mr. Zuo has a smile on his face. Who says that the infiltration phenomenon is completely a bad thing? Some infiltration creatures left by Luo Han have completely changed the intelligence and physical level of the next generation of human beings in the cold city. Human beings who stand up from the ruins will be a hundred times or thousands of times stronger than before. For the whole civilization, if they can completely survive this infiltration If we go through the crisis, then human civilization will go further.

"0.08912372 seconds!" Tang Xiuxiu was the first to give the answer. Li Weihan next to him moved his mouth. As soon as he saw Tang Xiuxiu say it first, he quickly swallowed the answer and hummed unconvincedly.

Mr. Su smiled and nodded. Tang Xiuxiu was right. She didn't say anything and waited for the children to turn this number into an intuitive impression.

The children calculated the answers one after another, all of which were 0.08912372 seconds. Suddenly, a little surprised and said, "Ah, the big hero is trapped in the black hole for less than 0.1 seconds!"

Once reminded, the children reflected, and their eyes widened coincidentally: "It turns out that for the big hero in the black hole, 20 years have passed outside, and he is still stuck in the moment when the black hole formed."

"Time is like a white colt in a gap. This was originally a metaphor of poets in ancient times, but it was actually reflected in the great hero." Mr. Su said gently, "I was as old as you ten years ago. I came here for the first time to visit the south black hole and think of the big hero in the black hole. Ten years later, I will come here again. If the big hero can see me, I'm afraid the time between these two round trips will not be enough for him to blink his eyes."

Tang Xiuxiu whispered, "Teacher, didn't you say that the great hero will come back to us and lead our cold city out of the mountains and drive away those annoying monks?"

Teacher Su was silent. When she was young, she also looked forward to the return of the great hero as Tang Xiuxiu, but as she grew older, she also knew that this might be just an extravagant hope and a legend. If the great hero is also a normal organism, it is impossible to survive in the black hole, let alone escape from the gravity of the black hole. It's in the world.

Seeing that Mr. Su didn't speak, the children were a little anxious. Tang Xiuxiu's eyes turned red. Li Weihan came up and took the initiative to take Tang Xiuxiu's hand and said, "Xiuxiu, don't cry. My father said that the great hero will definitely come back. When I grow up, I will join the army and defend the cold city with the big hero."

"Hmm!" The children nodded one after another.

Mr. Zuo sighed gently. What a good child. Suddenly, he lowered his head and saw a line of red letters sliding silently on the surface of the gloves: "A large number of living beings are approaching, 43 ordinary human beings, a monk in the training period, a second-level double-headed magic horse..."

Mr. Zuo stood up for fear of affecting his children's class and turned his gloves into silent alert mode. He didn't expect that when he saw the children calculate the black hole time and met someone entering the mountain. According to reason, there are many monsters around the black hole in the south of thexia, and he could not come in without a large number of monks in a group. It may be that the mountain has been blocked by heavy snow recently. He forced the monsters back to the cave, which made a hole for people.

"Mr. Su, take the children back first."

Mr. Zuo was afraid of scaring the child, so he shouted to Mr. Su with a smile. Mr. Su was stunned, but when he saw the faint red light on Mr. Zuo's gloves, his face suddenly changed. She quickly opened the bag to find the white stick. The white stick has an alarm function. Within 15 kilometers of radius, people or large monsters will call the police. She turned over for a long time. I didn't find it, and then I remembered that after the white stick gave it to Li Weihan to drag the body of the magma salamite back to the pine forest, it was not returned.

The child must have forgotten the door and passed the white stick back. Teacher Su stared at Li Weihan angrily, but now he has no time to settle accounts with him and quickly organized the children to retreat to the pine forest.

But the children's luggage dispersed and packed up slowly. When they were ready, more than a dozen double-headed horses rushed out of the dense forest and came to the grass.

Mr. Zuo's eyes were cold and he gestured to Mr. Su. Mr. Su quickly hid behind Mr. Zuo with some panicked children.

It was Ma Tiewu and his lost hunter team that rushed out of the woods. They entered a warm zone without snow without going far in the direction pointed by Brother Wang. Ma Tiewu felt inappropriate, but his men turned out to be bandits. They were already constrained and were bored by the heavy snow for several days. As soon as they saw this In a spring-like place, he immediately got excited and had to explore the way forward one by one. Ma Tiewu had no choice but to let all the staff come to the door quickly to pass through this strange area as soon as possible.

Who knew that it was so unfortunate that Ma Tiewu's team was heading for the Lingnan black hole, rushed out of the dense forest to the grassland, and met the children who came out of the cold city.

Ma Tiewu didn't expect that there were still people in this strange place, a middle-aged man, a girl in his early 20s, and more than a dozen children in their teens. They didn't look like monks, but like the classmates and teachers in Ma Tiewu remembered when he was a child.

"Wow, what a beautiful girl." The eyes of the bandits behind Ma Tiewu fell on Mr. Su. The little girl was so beautiful, with thin eyebrows and big eyes, white skin like milk, black and smooth shoulder-length hair, wearing a refreshing floral skirt, full and tall breasts, standing on the green grass. Standing is like a wild lily that people can't put down.

These bandits live in an undetermined place. They usually just browse kilns. It is rare to see any good women. In addition, the outside world is winter, and no matter how beautiful women are, they are tightly wrapped. How can Mr. Su's cool dress well. In contrast, the sexual interest of the bandits is stimulated and indewd. Whistlings sounded one after another. If it hadn't been for Ma Tiewu, I'm afraid he would have rushed up.

Wang Shur also stared at Mr. Su. After a while, he looked at Tang Xiuxiu's. In comparison, the little girl was more beautiful. Although the girl's appearance had not fully developed, it was a beauty embryo at first glance. Monk Wang suddenly remembered the rumor about the furnace tripod. It is said that the alien world The monk will grab some nuns to make a furnace tripod, which can not only increase the speed of cultivation, but also enjoy the blessings of all people...

Li Weihan found that Brother Wang was staring at Tang Xiuxiu with lustful eyes. His eyes were about to catch fire. He took out a small black ball from his backpack, gently clenched it in the palm of his hand, and stared at Brother Wang fiercely.

"Wang Xianshi... Wang Xianshi... Wang Xianshi!"

"Ah, ah, what's the matter, Captain Ma?"

After shouting three times, Brother Wang came to his senses. Ma Tiewu was angry, but it was not easy to attack. He suppressed his anger and asked in a low voice, "Master, do you think these people are immortals?"

Monra Wang shook his head: "They are all mortals."

Ma Tiewu nodded, turned his head to look at the huge black ball on the left, and then immediately came to Mr. Zuo. He lowered his head and asked, "Who are you? Why are you here? Is this black ball the legendary Lingnan black hole?"

Mr. Zuo didn't look at Ma Tiewu, but has been looking at the team behind him. Most of the two-headed magic horses sat on their bodies, and the total number of more than 20 double-headed horses totaled 44 people. Like the warning on the back of the gloves, he was secretly relieved. This group of people did not ambush but rushed out directly. It seems that it was not I came here specially, but if I pass by, the trouble will be much less.

Thinking of this, Mr. Zuo was relieved and the corners of his mouth rose slightly.
