After simply becoming familiar with most of the magic, Zhang Jin began to selectively practice some magic that he needed to master now.

The first in the list is of course not the disarming spell, but the brain defense technique, also known as the brain occlusion technique.

It's a magic designed to ward off the dementors' minds, with no wands and no spells, but it's one of the most difficult to master.

Almost all of the top people in the world have mastered this magic, after all, everyone always has secrets in their hearts that they don't want to be known, and people who can't even hide their own little secrets are obviously impossible to succeed.

The master of Occlumency, which also hides one's emotions and keeps oneself calm at all times, is not controlled by emotions, and creates false emotions and even memories to deceive others.

And Zhang Jin's mind is that there are too many secrets that cannot be known, and the differences caused by the fusion of the two souls also need to be concealed, and the change in behavior can be attributed to the fact that the blow is too great, but if it is discovered by others, the spiritual pleasure will be over.

For Dumbledore, Severus had just lost his beloved, and it was better to die than to die, and to the rest of the Death Eaters, the Dark Lord could be dead, and none of them could explain why you were happy.

Well, it's hard to hide the excitement, at least if it's a high-level Occlumency.

At the same time, it is necessary to cover up the changes in one's own magic and the changes in the soul that may be perceived, which ordinary people may not be aware of, but Dumbledore can.

So far, though, there hasn't been much progress, and although Severus has memories, there are always things that go wrong when it comes to using it step by step.

Severus himself is already a master of brain occlusion, but what this requires is to empty his mind as much as possible, empty his brain, not to think, not to recall, not to perceive, for Severus is simple, but for the current Zhang Jin is difficult.

Originally, Severus was suddenly hit, and there was already a gap in his brain, and Zhang Jin, who was fused, was an ordinary person, but now he couldn't even control his own emotions, and his originally closed brain was already full of holes.

Obviously, for this kind of magic that involves the soul, spirit, and will, when the soul changes, it is absolutely difficult to release it perfectly.

This also explains why all other spells are fine, but they don't work well with things like Brain Defense, Patronus Charm, and Unforgivable Charm. These are all kinds of magic that involves the soul or requires the cooperation of the mental will.

Like Nymphadora in the original book. Tonks fell in love with Lupin, the Patronus turned into a wolf, and George. Weasley witnesses twin brother Fred. Weasley was so heartbroken after his death that he was never able to cast the Patronus Charm again.

All of this suggests that mood changes have an effect on magic, and that there are many spells that require volitional cooperation to be released, such as Occlumency.

Now Zhang Jin's biggest problem is that he can't empty his brain, and he can't be like Severus without thinking, remembering, or feelings.

After trying a few times, Zhang Jin had no choice but to give up, this method is not suitable for himself, as an ordinary person who has been nurtured by modern society, it is too difficult not to be emotional.

I remember that Severus mentioned in his memory that in addition to not thinking and emptying his brain, another way to resist the regent's thoughts is to think about something that the boring other party doesn't want to see, or just keep yourself in a memory.

And the scene where Severus feels the death of his beloved is very appropriate.

For a long time after that, Severus was in a shroud of despair, with nothing but despair, remorse, and nothing else in his mind, as long as this memory was slightly modified to remove the content about Lily, and what was left was an excellent defense vehicle.

Whether it's Dumbledore or a Death Eater, feeling such despair, regret will automatically make up for it. As long as you can resist a while, it's fine.

After all, he is not a vegetarian, although some magic is not proficient, but after all, the magic has increased a lot, after a period of relief, even Dumbledore's Regent has the confidence to resist, and I believe that Dumbledore After the last temptation of the real Severus, it is impossible for Dumbledore to use his wand to recite the Regent again.

As for Lucius. Malfoy and the other Death Eaters didn't have Dumbledore's ability, so they were naturally not afraid.

The next thing is how to pack and modify his memory, Severus's memory hasn't been read yet, there are too many memories of nearly 20 years since I was a child, and it doesn't seem like I can selectively block some unimportant memories.

Zhang Jin looked at everything in detail when he was looking at it, and he watched it continuously.

Although the process is very fast, it is even more than watching a quick movie, and it has been imprinted in my mind before I even watched what happened later, and I think I am reminiscing.

In retrospect, even dreaming takes time, and these days of practicing magic during the day, fusing memories day and night, it's like not sleeping for several nights.

But don't say it, when Zhang Jin walks out now, anyone who sees it will feel like the sky is falling apart, but there is no need to do other disguises.

And the memory of Severus's collapse is something Zhang Jin doesn't want to see, that memory is too desperate, like falling into a bottomless hole, the whole person is falling, the whole heart is twitching, and occasionally the woman with blood flashes makes the process longer, and there is no end in sight.

Originally, I just felt that this was the state, and I couldn't slow down for a long time, and I even kept hinting that what I was seeing was a movie, and I was no longer the original Severus. Snape.

And now to re-enter it, it's hard to just keep the mind, and to do it is to delete Lily. Evans's picture doesn't know how many times he has to endure it.

Every time I woke up, I could feel the tears on my face, and now I didn't need to pretend at all, and I felt that I was no different from the original Severus.

The final result is to put the memories of the 21st century brought by Zhang Jin in the innermost layer, and the outer layer is wrapped in Severus's memories, and finally a big black hole covers all of these, and anyone who looks at it has to walk through this hole.

This is no longer the original brain occlusion, it should be regarded as a kind of memory readjustment, adjust the position of the memory, expand and stretch the memory that collapsed and fell into the black hole, and play a role in delaying and resisting the regent's thoughts.

As long as you gain some reaction time, it is good not to be touched by the deeper memory in the first place.

As for the master-level Occlumency technique that Severus originally mastered, let's forget about it, and maybe we can practice it in the future.

You can't just say that the Occlumency exercise failed.
