Hogwarts: Is this junior good or evil?

Professor McGonagall suppressed the chaotic voices of the crowd and asked in shock and excitement: "I just want to ask one question, what is the essence of disappearance?"

Yang Tian smiled bitterly and replied, "Professor, this is very abstract and difficult to explain clearly in words. Can I try to explain my thoughts?"

After getting Professor McGonagall's approval, Yang Tiancai continued, "There is a saying in the Chinese Tao Te Ching, 'One begets two, two begets three, three begets all things, and everything is from the same source. So let's assume that the source of everything is 'one', and the summoning spell is the process from 'one' to 'two', and then to 'all things'; the vanishing spell just turns 'all things' back to 'one'; the conversion spell is the process of two 'twos' or 'threes' replacing each other but not returning to one. My final operation is the continuous operation of reversing all things to 'two' or 'three', until the final 'one'.

"Origin, is it the origin? What is the origin? How can we find the origin?" Professor McGonagall murmured to himself, falling into deep thought.

The seniors looked at Yang Tian with admiration. What the junior said was very mysterious, but they seemed to understand it, but they also seemed to not understand it at all. But they knew that a new door was really opening slowly to them.

After pondering for a while, Professor McGonagall said as if she had realized something: "So determining this 'one' is the key. 'One' may be the origin, or the rule, or something else. But the method of determining this 'one' cannot be described in words, and can only be understood by oneself. What is the Chinese saying? It can only be understood but not expressed in words. Am I right?"

Yang Tian stared at Professor McGonagall in a daze, with a look of reverence on his face as he said, "Yes, Professor McGonagall, I remember when I was a child, my father told me that everyone has his or her own way, which can only be understood but not expressed in words."

In fact, Yang Tian lied, but he didn't lie. For him, the so-called "one" is an element, belonging to various arrangements and combinations of the five elements.

However, due to differences in cultivation methods, wizards cannot see the existence of elements in person, and can only perceive them vaguely like Professor McGonagall. Therefore, there is no difference between telling and not telling. In this case, he, who has lived two lives, will naturally not tell this secret.

After all, a man is innocent but guilty of possessing a treasure. If this incident really caused some malicious people to covet China's cultivation techniques, then Yang Tian would be doomed to die.

But even in the case of being unable to explain it clearly, Professor McGonagall can still vaguely sense its existence through her daily accumulation. It has to be said that she is gifted.

Professor McGonagall readily accepted Yang Tian's explanation. She was usually serious but she said excitedly, "Yes, today is really a rare day. I unexpectedly discovered a more subtle law of transfiguration. Perhaps it can be called microscopic transfiguration."

"It's the same for you, Yang Tian. Today's opportunity is equally rare for you. I have no doubt that you will understand everything today as you gain a deeper understanding of Transfiguration in the future. But I don't think it will happen so soon."

"And I have a feeling that today's micro-transfiguration may be of great help to the fire-breathing fish project we are about to launch. You can try to explore in this direction." Professor McGonagall said enthusiastically.

Yang Tian agreed with Professor McGonagall's point of view and nodded quickly. At the same time, he asked, "I know the direction of exploration, but I don't know much about my current progress in Transfiguration. What should I learn next? Should I continue to study the transformation of living things into non-living things?"

Professor McGonagall looked at Yang Tian with appreciation and said, "Since you can ask this question, I believe you have already realized your changes to some extent. Let me put it this way. After today, in the Transfiguration course at Hogwarts, your weakness will be in the advanced Transfiguration. For example, Trans-Species Transformation and Human Transformation."

"Human body deformation also includes Animagus and Metamorphmagus."

"As for cross-species transfiguration, your weakness is still your analysis of advanced species. For example, you want to transform a piece of wood into a Niffler, but you only know the Niffler's appearance but have no idea about its internal structure. Then your spell will inevitably be short-lived, or even fail."

"As for other aspects of Transfiguration, it can be said that you have mastered them thoroughly. If you don't believe me, you can read the relevant books. You will find that these books will not be difficult for you at all."

"So my suggestion is that you should start your studies from these two aspects. Of course, the analysis of advanced species requires more accumulation and massive reading. And my individual lessons for you will start from the direction of human deformation."

Professor McGonagall's in-depth and easy-to-understand explanation made Yang Tian fully aware of his own weight and put his mind at ease. So he thanked her repeatedly and returned to his seat to act like a good boy.

After that, the classroom returned to the atmosphere of heated discussion. Yang Tian liked this feeling very much, which was quite similar to his own study group. Even Professor McGonagall put aside her usual strictness and chatted with everyone.

This time, the party ended hastily until almost dinner time, and everyone felt that they had not yet finished.

After a quick dinner, Yang Tian hurried to the astronomy tower. Today was the day when Professor Sinistra of Astronomy was giving him a private lesson.

Although Yang Tian was temporarily unable to further practice astrology, the professor had been teaching him theoretical knowledge in private. As a successor recognized by Sinistra and an Awakened being, it was normal for him to have private lessons.

However, the professor was puzzled by the fact that Yang Tian did not practice astrology diligently, and he was quite critical of it, thinking that he was wasting his talent.

Yang Tian was helpless and could only explain that astrology and his Chinese cultivation method were mutually exclusive; only when his Chinese cultivation method made a breakthrough could he continue to cultivate, otherwise his body would suffer serious damage. Although what he said was true, he did not specify the specific details.

Hearing the seriousness of the situation, Sinistra gave up the idea of ​​letting Yang Tian practice quickly. But the professor would not relax at all on the theoretical knowledge, three times a week, one hour each time.

Fortunately, Yang Tian was also really interested in astronomy, so the two of them hit it off immediately, one taught seriously and the other learned enthusiastically.

And today, the little guy finally told Professor Sinistra the good news: after Christmas, he can basically continue to practice stargazing.

The professor was in a good mood after hearing this and let Yang Tian go back to rest early.

Yang Tian didn't act pretentiously and actually went back to the dormitory to sleep...
