Chapter 229: First Questions about Alchemy

Although this grand commendation ceremony was very successful, and although Yang Tian and his friends gained great fame through this ceremony, in Yang Tian's eyes, everything was not that important. Even on the day he returned to Hogwarts, Yang Tian once again plunged into his intense and fulfilling study life.

For example, today, Yang Tian arrived at teacher Nicolas Flamel's laboratory on time and discussed his learning questions with him.

"Teacher, why do I feel that there are some problems with the statement about obsidian refining in this book?" This was the first time that Yang Tian raised a question since Nicolas Flamel began teaching him.

"Is there a problem?" Nicolas Flamel frowned. He had personally verified this book. Especially the obsidian, as a magical material often used in alchemy and one of the important raw materials for making the Philosopher's Stone, he had tested it repeatedly and he had absolute confidence in it. But today, his newly accepted student told him directly that there was a problem with this formula. How could he not be angry at such a frivolous attitude?

But he did not directly discourage Yang Tian's enthusiasm. Instead, he asked seriously: "Tell me what you are confused about."

"According to the books, the source of obsidian is black lava. When refining, it needs to be heated to 2000c at a high temperature, and then the liquid obsidian is cooled to obtain refined obsidian. It is a mineral with a very low refining cost." Yang Tian said seriously.

"Yes, that's right. With such a clear and simple refining process, what else could go wrong?" Nicolas Flamel became more and more puzzled.

Yang Tian carefully sorted out the results of the two days of intelligent brain deduction in his mind, and then said solemnly: "This is a big problem, teacher. In my opinion, after such refining, the internal structure of obsidian will change slightly. Strictly speaking, this is already a different substance from the real obsidian."

"How is it possible?" Nicolas Flamel couldn't believe it, and then he emphasized: "I have been immersed in this obsidian for many years, and I will not make such a low-level mistake. All the obsidian extracted will undergo a series of tests. What I want to say is that the obsidian extracted by this method fully meets the characteristics of obsidian."

Yang Tian said seriously: "Teacher, you will question everything I say now. Why don't we speak with facts!"

Hearing this, Nicolas Flamel showed an interested look and said, "Tell me about it." He also wanted to teach his disciples a lesson with facts.

"We will refine the obsidian according to our own ideas, and the result will come out naturally." Yang Tian said.

"It seems that you have already come up with a complete set of ideas for this problem." Nicolas Flamel's mood improved a lot. It seems that his disciple is not aimless. However, he is also confident in his alchemy. Maybe this is a common problem of geniuses? It is difficult to be easily convinced of something that has been determined.

Thus, under the auspices of Perenal Flamel, the competition between the two officially began.

In fact, the refining of obsidian is really a very simple thing. Raise the flame temperature to 2000c, put the ore in it, wait for it to completely liquefy, cool down... Nicolas Flamel only took a few minutes to complete the whole process. After doing all this, he stared at his apprentice's operation without blinking.

Yang Tian's previous operation was exactly the same as his, but when the ore was about to melt, he threw a section of tungsten wire into the flame. Seeing that the obsidian ore was already liquefying rapidly, the surface of the originally insignificant tungsten wire began to show white crystals. Such a change surprised Nicolas Flamel and his wife, but they did not disturb Yang Tian's operation, but chose to wait and see.

Just before the obsidian ore completely liquefied, Yang Tian had taken out the tungsten wire, peeled off all the white crystals and crushed them into powder; but when the obsidian liquid gradually cooled down, he added the powder into it, stirred it thoroughly, and continued to cool it down completely.

Both pieces of obsidian were refined. Nicolas Flamel said nothing, but began to test the data of the two pieces of obsidian one by one... He wanted to speak with facts.

But the final result shocked and confused him: "There is no doubt that you have indeed refined a piece of genuine obsidian. Moreover, the obsidian you refined is undoubtedly better than mine. It has a faster magic speed and lower magic loss, which is indeed a significant improvement. But if you say that the structural characteristics of the obsidian I refined have changed, this..."

"Teacher, after reading a lot of alchemy books recently, I have come to a conclusion. I think the main reason why obsidian has been used as a magic conduction material in alchemy is not because of its conduction speed and low energy consumption, or it is more than that; after all, there are many other alchemical materials that meet these two points. I think the biggest feature of obsidian is its immovability and purity when conducting magic."

"I agree with this, but the obsidian I refined also has the same characteristics?" Nicolas Flamel said, while doubtfully releasing a fire spell on one side of the obsidian he refined. After just a moment of conduction, the fire spell shot out from the other side of the obsidian, and the volume and strength of the magic did not seem to change. "

"No, teacher. This is just an appearance." Yang Tian said seriously: "Your testing method does not meet the rigorous standards of alchemy."

Nicolas Flamel blushed when he heard this, and he quickly explained: "I simply showed you that the Fire Curse is still the Fire Curse, and the transmission has not deviated at all."

"What about purity?" Yang Tian asked with a half-smile, "Or to put it another way, isn't there any deviation in the time return voucher?"

As soon as he finished speaking, Yang Tian took out a small piece of mithril from the experimental table and began to carve it. In just a moment, he used the fire element to carve a runic word "fire" on it.

This is also the result of Yang Tian's recent efforts. Ancient runes are an important part of alchemy. Many alchemical props need runes to be engraved to achieve the best effect. As a master of alchemy, Nicolas Flamel naturally cannot ignore such an important lesson. In the alchemy book given to Yang Tian, ​​there are a lot of ancient runes.

The ancient runes are indeed complex. It is not as simple as memorizing the 24 letters. Each letter and each stroke may have thousands of variations; success or failure. It was with the help of the intelligent computer that Yang Tian barely figured out the relationship between them recently, and finally completed the depiction of the two forms of the two runes of water and fire...
