HP: After binding to the strongest wizard development system

"You can go back, but I have to remind you that your current expression and complexion are really ugly." Snape's eyes seemed a little unbearable. After all, Till, who had always smiled steadily, now had a bitter look on his face. .

Snape felt as if he was crushing a flower that was about to bloom.

Teal looked at Snape resentfully. Isn't it because of what he said just now that my face and expression are ugly now?

Tyr tried hard to suppress his temper, said goodbye to Snape politely, and then turned to leave the office. But as soon as her hand closed on the door handle, Snape said something to her.

"I almost forgot, Miss Emery, please take away the aura of dark magic on your body."

"What?!" Tyr turned to look at Snape, shock in his eyes. How did Snape know about his learning of black magic? !

Teal hoped that Snape could give him an explanation, but Snape had already lowered his head and started clearing away the papers on the table.

If Till hadn't really heard what he just said clearly, Till would have doubted whether he was hallucinating.

Therefore, Snape discovered her learning black magic because of the dark magic aura in her body.

Tyr lowered his eyes and politely said goodbye to Snape again, this time leaving with a bigger step.

She was already upset.

[System, do I really have the aura of black magic on me? ] Anxious and worried, Thiel did not dare to meet anyone else. He hurriedly ran up to the room on the fifth floor, closed the door firmly and asked the system.

The system tested Tiel's whole body and finally came to a conclusion: [Sorry, host, I forgot to remind you. Learning black magic will not only leave a huge shadow on your body and mind, but also cover your body with the easily detectable aura of black magic...]

After the system's apologetic but patient explanation, Till finally understood the so-called black magic aura.

The tyranny of black magic is not only reflected in its power after use. Once you have learned black magic, the aura of black magic will more or less remain in your body.

Till even kept the three unforgivable curses on his lips and went into the practice room to practice for several hours.

It's hard to imagine whether the aura of black magic on her body is strong or not.

Till felt that she was lucky. If it weren't for the fact that she had been busy recently and rarely appeared in front of the professors, and Professor Dumbledore and the others were also busy, it is estimated that the strong aura of dark magic on her body would have caused her big trouble. .

Fortunately, according to the system, the aura of black magic cannot be hidden.

There is no need for Till to stop practicing black magic. As long as Till drinks a special potion or wears the hair of some magical animals on his body, the aura of black magic will not be detected.

Of course, special potions are hard to come by, and there are strict requirements for the hair of magical animals.

However, after reading the information provided by the system, Thiel found that neither of these two things were rare for him.

It is easy for Till to purchase the potion materials needed to make special potions, otherwise her status as a potion master would be too low.

The hair of magical animals usually comes from unicorns or thestrals.

Of these two magical animals, the former is a symbol of purity, and its hair itself is precious. It is said to have the ability to purify dirt. Teal had read the information and knew that purifying filth was too exaggerated, but it was still very easy to cover up the aura of dark magic firmly.

The latter, the Thestral, although many people think it is ominous and once regarded it as a symbol of death, but those who really understand it will know that the specialness of the Thestral occupies a special position among magical animals.

Till himself likes Thestrals very much, because Thestrals' eyes are also silver-white, and without pupils, they look even cooler than Till's eyes.

Due to his affinity and bestiality, Till is full of attraction to magical animals. As long as they are magical animals with a pure heart, they will show strong kindness to Till.

Till has always maintained a very close relationship with the unicorns in the Forbidden Forest. Although she rarely goes to the Forbidden Forest, every time she goes to the Forbidden Forest, she will meet the unicorns more or less.

Unicorns have long lifespans and excellent memories, and Teal's breath is firmly imprinted in their minds.

As long as Teal appears within the Forbidden Forest, the unicorn will sense it and come to interact with Teal.

Till also brought some gifts to his unicorn friends, but the combs and the like could only be used by the unicorns when Till was present.

Unicorns like to rinse their hair with water to make themselves clean from top to bottom, but combs and other things...

The unicorns found it unsightly to comb their companions with their mouths in their mouths, so the combs Teal gave them could only be kept in their collections.

However, Thiel only made mistakes in giving gifts the first few times. After that, he brought delicious and fun things, and the unicorns were very happy.

It would be easy for Till to trade some hair back with the unicorns. If not, he could still buy it on the market - it's just that it's often expensive and unavailable.

The Thestral's hair is also easy to get. As long as Teal tells Hagrid, who takes care of the Thestral, Hagrid can give Teal a bunch of combed Thestral hair at any time.

The Thestral tail hair, which is precious to wand makers, is described as a bundle by Hagrid.

The problem of concealing the aura of dark magic was easily solved by Teal, but because Snape suddenly raised it that day and frightened her, Teal was on tenterhooks for several days after the concealment.

I was afraid that when I walked in the castle, I would be discovered by the professor who met me.

But Teal was soon relieved, because the aura of dark magic on her body could not be felt by Professor Snape even when he was communicating about potions face to face.

This made Thiel even more enthusiastic about learning black magic.

You can't put the potion you worked so hard to brew and the gray hair you earned to use.

Moreover, Till would also ask the system to monitor the intensity of the black magic aura on his body from time to time. Not to reassure herself, but she found that she could intuitively understand her level of dark magic based on the intensity.

The deeper and better he learns black magic, the stronger the aura of black magic in Till becomes.

Although Till was diligent in studying dark magic during the summer vacation and his aura was already hanging on him, during the first period of school, neither Professor Flitwick nor Professor McGonagall noticed it.

It shows that although Till was able to use several sinister black magic at that time, he was still not proficient.

But it was different now. As Till's understanding and use of black magic gradually deepened, the aura of black magic spread all over Till's body.

If Snape hadn't reminded him from time to time, Till wouldn't have known about the existence of dark magic until he was discovered by the professors.

She always thought that traces of black magic could only be produced after the magic power of the dark wizard was left behind.

Traces of dark magic! Teal suddenly thought of the crystal balls placed in many places in the castle.
