Chapter 267 Liu Kan

As soon as he returned to the Armor College, Zheng Yinan went to his teacher's residence. Although he had many teachers in the Armor College, the only thing he could respect was the one he was visiting now.

Although he felt ashamed to ask the teacher about such a low-level elixir about clearing bones, he gritted his teeth and made such a choice in order to find out the reason why he had been trapped.

His teacher, surnamed Liu Mingtan, is not obvious in the armor college, but he is treated as a second-class teacher. Even the teachers who have been working with him for many years and the principals of the armor college do not know his profound knowledge. Only Zheng Yinan knows how powerful his teacher is. He is a genius. With such achievements, he also has an inseparable relationship with Liu Tan.

Just like Liu Kan's low-key relationship at the Armor College, the teacher-apprentice relationship between Zheng Yinan and Liu Kan is not known to outsiders. In the eyes of others, they are just a pair of forgetful friends. They think that Liu Kan's ability to make friends with such a genius is not a lucky thing in their last life. They can't think of most of what Zheng Yinan has learned. It's actually from Liu Han.

Liu Kan's character is as low-key as his knowledge, so he doesn't go out easily and usually stays in the exclusive teacher's building of the Armor College.

Zheng Yunan obviously hesitated to come to Liu Kan's door, but he still made up his mind to knock on his teacher's door.

"Yinan?" Liu Kan's kind voice came from the room. He knew that few people would knock on the door except his beloved disciple Zheng Yinan.

"Hm, teacher, it's me."

The door opened quickly and Zheng Yinan walked in.

Looking at his beloved disciple Liu Kan's eyes full of kindness, but he soon became serious. He knew that Zheng Yinan would not come to find him easily if he had nothing to do. "Yinan, what's the matter?"

"Teacher, the student fell on a kind of bone-clearing elixir."

"Bone-clearing elixir? One kind?" Liu Kan was a little surprised. He didn't expect that Zheng Yinan, who had just stepped into the threshold of an intermediate alchemist, actually encountered a problem on the clear bone elixir. However, Zheng Yinan had already refined the bone elixir to the point of perfection. How could he encounter problems? Zheng Yinan's "one kind" makes him a little puzzled. He knows that with the development of alchemy technology, the performance of bone-clearing elixir has already reached an optimized stage, and it is impossible to go forward at all, that is to say, there are several theories about bone-clearing elixir at all. Will anyone be so bored to add some herbs or materials to make a bone-clearing elixir that is much worse than ordinary bone-clearing elixir? He can only think so.

Looking at his teacher's disbelief, Zheng Yinan talked about the problems he encountered on that kind of defective bone-clearing elixir these days.

"Is there such a thing?" Hearing that the elixir looks like a defective product, it has the effect of the best elixir. Liu Han suddenly looked a little surprised. "Take that elixir and let me have a look." He knew that if this was the case, this bone-clearing elixir is likely to be a newly developed bone-clearing elixir with better effect than those best bone-clearing pills.

Zheng Yinan immediately handed four such bone-clearing pills to his teacher. Of course, he did not say how ridiculous the price of these elixir was. If he let his teacher know that he had used such a high price to bid for these low-level elixirs, he would die of shame.

Liu Kan took the elixir handed over by Zheng Yinan with a solemn face. He knew the strength of his beloved disciple, so although he was his teacher, Liu Tan was still extremely cautious.

The color of this bone-clearing elixir is not much different from that of the inferior bone-clearing elixir. No, it is worse than the color of ordinary defective bone-clearing elixir. Liu Kan quickly distinguished their color. How could such a poor color have the medicinal effect of the best bone-clearing elixir? With Liu Kan's profound knowledge, he also can't figure it out.

Looking at his teacher's look, Zheng Yinan also became increasingly nervous. He felt that things were not as simple as he had thought.

"Teacher, I found that this elixir is either mixed with the sixth herb. With the original formula of bone-clearing elixir, I think the problem should be with this sixth herb."

"The sixth herb? Then it seems that the teacher has to try to analyze it, otherwise there is really no way to figure it out. Well, Yinan, you go back first and come to the teacher after dinner in the evening. If there is no accident at that time, the teacher should also make it clear.

"Then I'll say goodbye first." Every alchemist does not want others to be disturbed when making or analyzing elixir, and even his knowledgeable teacher is no exception, so Zheng Yinan left with great knowledge.

After Zheng Yinan left, Liu Tan quickly began to analyze the bone-clearing elixir given by Zheng Yinan.

After the dilution of the special medicinal liquid, this kind of clear bone elixir floats out a special fragrance. Although this fragrance seems to be no different from other bone elixir, Liu Tan, who is experienced, still smells the difference, and such a slight difference makes him more cautious.

Although Liu Tan has not touched such a low-level elixir as clear bone elixir for many years, he has not lost his familiarity with clear bone elixir.

However, with the passage of time, Liu Kan found that his familiarity did not seem to have much effect on the analysis of this elixir. Is this really a newly developed bone-clearing elixir? He really doesn't know who is so powerful that he can break the limit of bone-clearing elixir.

Time still passed minute by minute. Although Liu Kan's hand and the ground were full of consumed herbs and materials, and the liquid in the porcelain basin was getting less and less, Liu Kan seemed to make no progress. His eyebrows were still deeply frowned, and his silver hair seemed to declare his helplessness.

Liu Kan's study time is indeed very profound. His yellowed "Wancao Collection" has never been moved at all, so he took the herbs in the medicine cabinet with his own cognition. Similarly, his speed was much faster than Zheng Yunan, and each diluted medicine was quickly consumed by him.

However, despite this, he still has no clue.

Like Zheng Yinan, he is stuck on the sixth material.

I'm all like this. No wonder Yinan can't analyze it. The person who refines this kind of bone-clearing elixir is really strange, Liu Kan muttered. Despite countless failures, he became more and more energetic, and his eyes seemed to emit a hot light.

I don't know how long it took, and Liu Kan's movements seemed to slow down a little. He knew that it was because of his old age and weak physical strength. In recent years, at this time, he has to stop the work at hand to rest, otherwise he will have to rest for a period of time to recover his original physical strength and spirit. Only at this moment, he obviously hesitated.

His students are coming. If he sees that he can't even analyze it, what can he do? Liu Kan, who thinks so, continues to work hard to deal with the medicine in the porcelain basin.
