"There are many different ways in which a wizard wants to transform a life form. ”

"Transfiguration potions, transfiguration spells, transformation charms, etc...... These solutions lead to the same goal, but even the same Transfiguration spell can be used differently by different wizards. ”

"A powerful wizard can completely and completely transform into another life form, such as the Mr. Zhang in the Shushan Pavilion...... And the vast majority of ordinary wizards, after transformation, will always unnaturally embody some characteristics of one kind or another. ”

"Just like wearing black glasses, a black pattern will appear around the eyes of a deformed animal, and a fat animal will still show a strange body shape after ...... transformation."

At this point, Professor Yi paused, and then asked Zheng Qing a question:

"Do you know that the law of trigonometry is impossible?"

"Impossible triangle?" Zheng Qing repeated this slightly familiar word, searching his intestines, and his face quickly showed a hint of excitement: "Do you mean the Mundell paradox......?

A few weeks ago, after a kitten was killed on the shore of Linzhong Lake, Zheng Qing looked up information about second-degree murder in the library and learned about this law from the side.

This is a well-known fundamental law in the realm of transfiguration magic.

"Very good!" Professor Yi interrupted the young wizard's explanation and nodded in satisfaction, "Then I don't need to explain it to you in detail...... It saves us a lot of time. ”

Zheng Qing immediately closed his mouth.

"It is impossible for a single wizard to achieve the free transformation of species, the independence of will, and the stability of magic at the same time. The professor repeated Mundell's paradox, staring at the young wizard in front of him: "The independence of the will is particularly crucial, and it is an important criterion for judging whether a wizard can maintain himself...... The reason why I let you understand that notebook on your own before announcing the treatment plan to you is because there is a very powerful magic attached to it. ”

"It can leave a deep imprint in the depths of your soul to anchor your sense of self...... If you can't really understand what is in the notes, then we can only use external forces to make you lose your magic and keep your sense of self stable...... This comes with a number of unnecessary risks. ”

Zheng Qing felt the hairs all over his body quietly explode.

It's a terrible thing to think about when your soul is silently tampered with.

Cold sweat seeped out of his pores, causing him to shiver several times in quick succession.

"But," he said, his voice a little dry, "I didn't seem to have any special feelings just now, that magic that affects my soul..."

At this point, he didn't go on.

Although it seemed inappropriate to feel that he had received a spell for no reason, it also seemed inappropriate to blame the professor who had cured him for it.

"I thought the soul was a very private sphere. The young wizard finally expressed his opinion in a very restrained tone.

"Rest assured, this magic has been certified by the Wizarding Alliance's SCL and is on the list of safe spells...... Any wizard above the registered level has the right to use the magic on the list against any other wizard within the boundaries of the Umno Alliance. Professor Yi immediately understood Zheng Qing's uneasiness and dissatisfaction, and patiently explained, "As for you, you don't have any special feelings...... This is a very normal situation. One of the characteristics of a safety spell is that it does not cause any adverse effects on the recipient. ”

"Then how do you tell if that spell has failed?" Zheng Qing couldn't help but ask.

"You gave a perfect explanation to the question I just asked. Professor Yi smiled, tapped his deep index finger on his temple, and said, "If you don't understand the content of the note, you won't be able to trigger that guardian spell, and you won't be able to answer my question correctly." ”

Zheng Qing opened his mouth, and finally closed it a little unwillingly.

For the first time, he had a slight fear of life in the wizarding world, and for the first time, he had a hint of a desperate desire to become stronger.

A weak wizard, in this world, there is no way to even guarantee the secrecy of his soul.

Think about it.

The two professors in the office seemed completely unaware of the young wizard's drastic psychological changes.

Lao Yao was still sitting quietly in the corner, as if his task today was to witness the process of Professor Yi explaining the treatment plan to Zheng Qing. It's just that some suspicious sounds that seem to be snoring faintly came from the smoke around him, which made people very suspicious of the current state of the dean of the Nine You Academy.

Professor Yi pulled out a slender branch from the drawer and gently brushed his fingers over it.

"Books," he muttered with a slight pause in his fingers, "the door to the temple of knowledge." ”

The transparent glass vitrines on the bookshelves opened one after another, and a group of elves flew in from nowhere, burrowed into the bookcases, and dragged heavy magic books in front of the professor.

Several magic books stood up restlessly, but they obediently collapsed on the table under the gaze of the divination professor, pretending to be a dead book.

"You need to understand the principles of Transfiguration within a year. Professor Yi raised his fingers slightly, and the magic books on the table were folded into a neat stack, slowly floating, and swaying into the arms of the young wizard.

Zheng Qing was almost crushed by these heavy books.

His eyes noticed that the top of the stack was "The Structure of Life: A Detailed Explanation of the Body Structures of 100 Common Creatures", and the hardcover cover could not hide the terrifying reality of hundreds of pages.

By visual inspection alone, there were more than ten books in his hand.

"It's... Zheng Qing tried to adjust his body's balance, and stammered: "A year's time, eat it all, just learn this magic?"

"Yes, all of them in a year...... This way, I can officially start teaching you Transfiguration in the first semester of your sophomore year. Professor Yi didn't seem to think it was a big deal, and his tone was very flat:

"Transfiguration is not a magic. If broken down, it is considered a subdivided field of magic, and most wizards will only be exposed to this advanced knowledge above the registered level. Because of your special situation, the school can make an exception to train you in advance...... I've given me plenty of time so that you can fully understand the concepts in the book......"

"Abundant?!" Zheng Qing groaned faintly, and tears almost fell: "I don't have so many books for all my schoolwork...... Isn't a year a bit short..."

"Time is short?" Professor Yi frowned and said with displeasure: "This is a matter related to your net worth and life, don't you have some sense of urgency to race against time?"

"No, that's not what I meant. Zheng Qing shook his head again and again, and immediately denied it: "I mean, can't we master a relatively simple transformation spell first?

"Transfiguration is a very serious matter, and it must not be faced with a sloppy and improvised. Professor Yi was obviously a little dissatisfied with the young wizard's attitude, but at the same time, he frowned at Zheng Qing's next question: "As for the ...... within a year, Since you have been living peacefully for eighteen years, it should be no problem to hold on for another year and a half..."

No problem......

Question......

Bar......

Zheng Qing felt that his eyes were dark, and he almost closed his breath.

Strict and irresponsible.

This very contradictory attitude was flawlessly connected by Professor Yi in one sentence.

The young government-funded student had nothing to say for a while.
