When sensing another will, to be honest, Zhang Jin was not surprised at all.

After all, the soul has not been fully fused for such a long time, and it is impossible to say that there is no reason.

It can only be said that the combination of soul perception has made Zhang Jin more confirmed.

Combining all the possibilities and speculations, there is only one truth: Severus's will is not completely gone, and he still has some remnants, commonly known as remnants!!

Well, please ignore this somewhat funny title, we can also call it obsession.

That is to say, although Severus took the initiative to seek death and took the initiative to give up his body including his soul to Zhang Jin, his subconscious has not completely disappeared, and what he thought and wanted to do at the last moment was still there, and these unwilling or persistent wills formed these obsessions.

Although it is few, it is difficult to integrate, these deepest obsessions in the heart are like the essence of the will, as the saying goes, the essence is not too expensive, 10,000 elites are worth 100,000 miscellaneous soldiers is a breeze.

It was because of the influence of Severus's residual will that the last soul did not merge for a long time.

And as time goes by, there will only be less and less residual will, so sooner or later it will be able to fully merge.

It's just that this time is not easy to grasp.

It's like Zhang Jin's will is melting and devouring Severus's will, the more the last bone is harder to gnaw, and the process must be more difficult in the end.

As for how to eliminate Severus's obsession faster, this Zhang Jin also has some speculation, maybe he can do some things that his obsession wants.

For example, protecting Harry instead of Severus, or helping to kill Voldemort or something, but these don't seem to be things that can be done in a short period of time, if it takes more than ten years to complete it, why do you do it, and the will to do it in more than ten years has long been gone.

Then it is necessary to learn from the practices of the predecessors who crossed over, whether it can be completed or not, first make a wish, make an oath, and appease the will that does not know what state it is.

Isn't this the rejection of the will of the world that the bigwigs are talking about? It's really like thinking about it, because the original will causes the soul to not be fully integrated, which would be strange if there was no rejection.

So Zhang Jin began to think about whether to make an oath and make a wish.

But swearing to protect Harry Potter, or swearing to kill Voldemort doesn't seem to be reliable.

Judging from Zhang Jin's understanding of Severus's memory, whether it is Harry Potter or Voldemort, it obviously doesn't matter, and there will only be one obsession, and that is Lily. Evans.

But what about it? Resurrect her, and then have a romantic love? Don't laugh.

Zhang Jin can only say that he will meet Lily when he has the opportunity in the future. Evans, of course, can only see souls, and it would be better to ask her to forgive Severus.

Of course Zhang Jin won't say the oath, if this is heard, wouldn't it be over, just say it in your heart, if you do it, you will naturally have a feeling.

It turns out that he really thinks too much, and he probably doesn't even have the will to think, so he can only think of other ways.

Speaking of which, when Severus left, in addition to despair, the most was remorse, remorse for what he had done, from the very beginning of the sentence "mudblood", to the final informant, and even asking Dumbledore for help, all of which made Severus regret, remorse, and then became Severus. Snape's despair.

This kind of despair is something that Zhang Jin doesn't want, and after experiencing it a few times, he never wants to touch it again, let alone eliminate or explain it, it's just a joke.

What Zhang Jin admires most is the heroines who can overthrow Severus after crossing over, this is only true. Protagonist. What can only be done by the daughter of the world, Zhang Jin said that there is nothing she can do.

Only by truly experiencing it can you understand Severus's relationship with Lily. Evans' paranoia.

After being subjected to domestic violence and neglect by his parents since he was a child, and then meeting a fellow student, he had an extremely sweet, fairytale-like beautiful time, and this period of life with Lily in Spidertail Alley is Severus's most precious memory, and it is also the only light in Severus's heart.

And it was Lily who brought the light. Evans.

Even if this period of time is relatively short, even if you meet more people at Hogwarts later, those people and wizards can't be the same as Lily. Evans is on a par.

This may also be the characteristic of every Slytherin, and almost every Slytherin has its own paranoia, which can be ambition, or madness, etc.

So it was almost impossible to replace Severus's light and only love, especially after killing her.

How deep the love is, how deep the hatred for himself is, these are not something that Zhang Jin can bear as a mortal.

Because of this, although Zhang Jin accepted all of Severus's memories, he also consciously hid that part, and never thought of thinking of himself as the original Severus, which can only be said to be unbearable.

So after feeling Severus's despair, Zhang Jin was even forced to keep thinking about some funny things, or to relieve the depression caused by that despair by complaining.

As Zhang Jin, who was born in the new era, grew up under the red flag, and lived in happiness, if he endured Severus's emotional torture for a long time, he would inevitably end up in collapse and madness.

Because of this, Zhang Jin admires Severus even more, he can bear it, he can keep his sanity, and even in the face of people like Harry, Lupin, Sirius, etc., he can stay calm, and even complete the work of a spy perfectly.

Shouldn't such a person be admired?

As for the other personality shortcomings, Zhang Jin should only think of the usual way of regulating emotions, otherwise Zhang Jin really can't think of how Severus did it.

Therefore, if the oath is useless, it can only slowly wear out those wills.

This also made Zhang Jin understand that the residual will can be consumed, in that case, can the will of the outside world be slowly consumed?

Isn't it your own to absorb the magic of the outside world and wear away the will in it?

If you have the chance, you still have to give it a try.

And I'm afraid that the stronger his will, the more his ability to wear and tear will increase, so that Severus's part of despair can also be experienced occasionally and used to hone his will.

The other is the contamination of the negative will when casting, which can also be slowly restored by the wear of the will.

In this way, in addition to trying not to use unforgivable spells, even some spells that can cause death can be used boldly.

The next few days were spent researching the making of potions.

One of the most important is the improvement of the wolf poison potion, Severus in the original book also did such a thing, Zhang Jin also wants to try, applying for a potions master also has to have a certain degree of achievement and popularity, improving the wolf poison potion and then publishing it is a good method.

And in addition to being able to make a potion to dissolve the magic to make a high-grade potion, there are some research results that can undoubtedly make the review easier.

Then it took a while to make a wand with Ollivanders, and the process was very smooth, although it could not reach the level of Ollivanders, but at least it was qualified.

After that, Zhang Jin made himself a spare wand with the dragon's heartstring as the core of the wand, the dragon's heartstring is better at this, although it is not loyal enough and easy to succumb to the strong, but it is indeed strong enough, and the most important thing is that it is durable, it is estimated that even Zhang Jin can use it for more than half a year.
