After continuing to chat with Dumbledore for a few words, Ye Siyu said goodbye to Dumbledore, he knew that some things should not be too tight, just give the conditions to attract the other party, he believed that Dumbledore's soul magic was enough to make Dumbledore give up the original plan to let Harry take risks.

As Ye Siyu thought, after Dumbledore learned about the existence of soul magic, he had already made a decision, that is, to try it and use Ye Siyu's soul magic to separate the Voldemort soul fragments from Harry's soul.

Although Dumbledore had arranged Harry in his plan early on, the main purpose was not to harm Harry, but to save him from becoming Voldemort's pawn, otherwise he could have destroyed Harry and Voldemort when he was a child, instead of waiting for Harry to grow up.

And the reason why he didn't immediately agree to Ye Siyu was because he still didn't trust Ye Siyu very much, the matter about Voldemort was very extensive, and a little carelessness could cause extremely serious consequences, he was already old and no longer as energetic as in the past.

In the past, when he was not old enough to be this extent, he couldn't say victory in the face of Voldemort, he was barely a match, this was still blessed by the Elder Wand, if he didn't have the Elder Wand, he would have been defeated by Voldemort a long time ago.

If Voldemort is resurrected, according to the current situation in the wizarding world, no one can stop the other party, so he must handle this matter carefully.

He was going to tell the person he trusted most about soul magic, and if something happened, he could deal with it accordingly, and that person was Snape.

"Professor, that kid's soul is parasitic with Voldemort's soul!?" , Snape said with a shocked look on his face.

"Hmm." , Dumbledore nodded, in fact, he had never been sure that Voldemort had soul fragments hidden in Harry's soul.

As Voldemort's teacher and nemesis, Dumbledore knew very well how terrifying Voldemort's magical attainments were, and although Harry's parents were strong, it was impossible for them to do anything to kill Voldemort, the Dark Lord who shocked the wizarding world, so he always suspected that Voldemort was not dead.

Especially when he saw the lightning-shaped scar on Harry's forehead as a child, he knew that Harry had been hit by the Avadaso curse.

The Three Unforgivable Curses were not blown, Dumbledore knew very well how powerful they were, even if he was hit, it would be absolutely impossible to live, but Harry did, so he very much doubted that Voldemort was not dead.

One day after Voldemort was destroyed, he used various divination techniques to determine whether Voldemort was dead or not, and as a result, he was told that Voldemort was not dead.

He began to investigate what Voldemort had done before he disappeared, and eventually he discovered that Voldemort had studied Horcruxes, and had done many things since then that were consistent with the ritual of making Horcruxes, so he knew that Voldemort must have made Horcruxes.

But he must not know exactly what it is, how much it is, the only thing that is suspicious is Harry, who believes that Harry has become Voldemort's Horcrux.

In order to prevent Voldemort from deceiving him, he sent Harry to her aunt's house, and then observed to see if anything unreasonable happened, and the end result was that Harry did not show anything unusual.

However, he didn't believe it immediately, but used various methods to detect Harry's situation, and finally he found that Harry had a magic in his body that did not belong to him that was protecting him, and this magic he knew, it was the magic of Harry's mother Lily.

From then on, he could understand why Harry was able to survive Voldemort's unforgivable curse.

It's just that he can't understand why Lily's magic has been active and obviously resisting something, so he has a guess in his heart that Harry has indeed become Voldemort's Horcrux, but because of Lily, it didn't work.

Of course, it was only a suspicion, and it was not certain, but even so, he made a plan based on Harry's situation and various intelligence.

As time passed, it was as if Voldemort had truly disappeared into history, which also made Dumbledore let down his guard.

Especially today, seeing the innocence and curiosity of magic that Harry showed after coming to school, Dumbledore was even more relaxed, and wondered if he was too worried.

However, all of this was broken when Ye Siyu revealed that there was an evil soul in Harry's soul, allowing Dumbledore to confirm that his previous suspicion was correct, that Harry was indeed Voldemort's Horcrux.

After the matter was decided, Dumbledore's heart was heavy, and he knew that the last thing he wanted had happened.

Fortunately, Ye Siyu also told him that there was a way to deal with this problem, which made him worry and hopeful.

Telling Snape now is to prevent Ye Siyu from being a Death Eater of Voldemort, and all he did was to bring Voldemort back to life.

Of course, he also knew that the odds of such a situation were extremely small, almost equal to zero, but this matter involved Voldemort, and even if it was almost unlikely, it was very likely to happen.

"So what do we do now?" , Snape said anxiously.

For Harry, the son of his rival in love, Snape didn't like it at all, and even said he hated it, but Harry's eyes were too much like his mother's eyes, and every time he saw those eyes, Snape would let go of the disgust in his heart, and now learning that Harry had Voldemort's soul fragment in his body had to make Snape nervous.

Dumbledore immediately informed Snape about Ye Siyu and soul magic.

"Can we trust him?" After listening to Dumbledore's explanation, Snape said in a deep voice.

Snape was friendly to Ye Siyu, the existence of magic and potions above him, but it didn't mean trust, before Voldemort was completely destroyed, he didn't trust anyone except Dumbledore.

"It should work." , Dumbledore muttered, his intuition told him what Ye Siyu's purpose should be when he joined Hogwarts School of Witchcraft and Wizardry, but he didn't know what the specific purpose was, but one thing was certain, that is, Ye Siyu's purpose had nothing to do with Voldemort.

If Ye Siyu wants to resurrect Voldemort, he can do it with his magical soul magic, and there is no need to tell himself at all, so he can be trusted at present.

"So what do we do next? Let Siyu Ye separate Voldemort's soul from Harry's body? Snape asked.

Dumbledore nodded, and now told Snape about it, and if anything happened to him during the separation, Snape could deal with it accordingly.

"Need my help?" , Snape continued.

"No, you can just continue to hide, this is our agreement." , Dumbledore shook his head.

Snape was a secret chess piece between him and Voldemort, and he didn't want Snape's identity to be revealed unless he had to.

Snape was silent, he understood what Dumbledore meant, so he didn't continue to dwell on this matter, but began to discuss what to do if something went wrong.

……

The next morning, Harry and the others woke up early, put on their wizarding robes and prepared for the first lesson of the day, the elemental magic class.

Normally, the first class for new students should be the history of magic.

However, elemental magic is a new curriculum and a new magic system at Hogwarts School of Witchcraft and Wizardry, and other teachers would like to listen to the lesson to see if they can give them some inspiration.

The classroom of the Elemental Magic Class was no longer the classroom of the Defense Against the Dark Arts class when he first entered this world, but a huge space that Ye Siyu had built next to the dormitory, in which he could play football.

"No matter how many times you watch it, Professor Ye's space magic is so shocking." , Charms professor and president of Ravenclaw College, Filius Flitwick, looked at the size of the classroom and exclaimed.

Space magic is also a very high-level magic in the magic world, and there are only a handful of people who can use it, and among these people, there is not a single person who can achieve Ye Siyu's level, as far as he knows.

McGonagall and the others next to him nodded in agreement, and the four of them admired Ye Siyu's magic attainments very much.

As the course began, Ye Siyu explained the basics of elemental magic little by little, just like the teaching who first entered this world, and it was a hardcover version, so that students and the professors who were auditing could understand it as much as possible.

"Is this elemental magic?"

"It's not like magic as we know it."

"Magic based on controlling the elements."

Unlike the ignorant students, the professors were amazed that they had heard a lot of new things that whimsical them, especially Snape, who focused on magic and potions, and who seemed to have discovered a new continent.

"Next, I'm going to teach you the most crucial meditation technique in elemental magic." After telling the basic knowledge, Ye Siyu began to teach formally, and after speaking, he snapped his fingers, and one after another balls of light recording the knowledge of meditation appeared around Ye Siyu from Ye Siyu, and then with a wave of his fingers, those balls of light floated in front of everyone, making the students exclaim.

Some daring students tried to grab the orbs, but when their hands touched them, they found that their hands were directly passing through them, and they looked like ordinary apparitions.

"These orbs of light contain meditation techniques, be careful, you may not use your wand to direct them into your mind." , Ye Siyu said.

"Without a wand?"

"So what to do?"

"Take it in your hands?"

……

The students' faces were full of doubt.

"Can't you use a wand to teach students how to cast spells without a wand?" Dumbledore lifted his glasses.

Although Ye Siyu did not use his wandless spell casting too much to promote in this rebirth, he became famous, even if he usually choked on drinking water, countless people would pay attention to it, not to mention Ye Siyu's characteristics that are different from ordinary magicians, which are even more eye-catching.

Many people want to understand the mysteries, and Ye Siyu didn't hide anything, teaching the basic knowledge of wandless spell casting to the other party for free when others exchanged magic cultivation techniques for him, and there was no contract like magic cultivation that couldn't be told to others.

It can be said that as long as anyone who has paid attention to Ye Siyu will know about wandless spellcasting, but just knowing, it is difficult for magicians who are used to using magic wands to help them cast spells in a short period of time.

From thrift to luxury, from luxury to thrift, this sentence perfectly interprets all this.

Casting spells with a wand is simple and convenient, you only need to practice spells, and you don't need other cultivation at all, and casting spells without a wand, you must first learn to feel your own magic, then you have to learn to control your magic, and then you start to learn to arrange elements, the comparison between the two is like elementary school mathematics and Olympiad, and it is not easy to learn.

"Quiet, whoever is the first to pick up the memory light ball and absorb it, then the academy where he is located will add ten points, and I can teach him magic cultivation techniques for free." , Ye Siyu didn't care about the students' doubts, and directly used the credits to tempt them, saying that more is better than doing more.

Instead of wasting saliva on discussions, give it a try.

Hearing that there was a reward, and that it was a precious magic cultivation technique, the students no longer considered whether they had a wand or not, and began to try to pick up the ball of light.

"Professor Ye, I want to try it too." When the students tried it, Dumbledore said a word to Ye Siyu, and the other professors also echoed it when they heard it, and they also wanted to try it.

Ye Siyu nodded, and with his right hand, the memory light ball reappeared and floated in front of the professors, asking them to try.

For a while, the classroom became quiet, and everyone was trying to pick up Ye Siyu's memory light ball.

A minute passed, and the memory ball floating in front of Dumbledore was held in his hand, as the power of the wizarding world, he was not like those headless flies like students, he knew very well what the key to picking up the memory ball was, that is, magic, although the absence of a wand made him very unaccustomed to it, and it was difficult to mobilize the magic power in his body, but it was not difficult for him.

Not long after Dumbledore picked up the orb of light, McGonagall and other old magicians next to him also held the orb of light in their hands, and they all understood the key to picking up the orb of light like Dumbledore.

Unlike Dumbledore and other professors who easily picked up the memory orb, none of the students could pick it up.

More than ten minutes have passed, and all the professors have absorbed the memory light ball, and began to digest the knowledge of meditation, reflecting the students, there is still no difference from before, let alone absorbing, and no one even picked it up.

"A reminder to you, the foundation of elemental magic." , Ye Siyu reminded.

Hearing Ye Siyu's words, many students' eyes lit up and they tried again.

"Professor, I made it!"

More than ten minutes passed, and a cheer broke the quiet atmosphere of the classroom.
