When Voldemort thought that Professor Sglughorn might reveal that he had asked about Horcruxes, extreme murderous intent flashed through his heart.

However, due to the influence of many factors, he had to modify Professor Sgrahorn's memory.

Not only was he afraid of Dumbledore, but he also "repaid" the professor for taking care of him.

Voldemort believed that modifying the memory of someone who had mastered such a deep secret and was not yet with him was the greatest gift to Professor Sglughorn.

He has two methods for this memory, one is to directly delete the memory, which is simple and crude; the other is to modify the memory, which is a delicate job.

However, the elegant Lord Voldemort did not choose the first crude method.

This method damages the memory of the person being cast, and can easily leave traces.

Some wizards who are proficient in memory magic can follow the traces to find clues and restore deleted memories.

This is even more dangerous for Voldemort and is not what he wants to see at all.

Moreover, as far as he knew, Professor Sgrughorn himself was a master of memory magic, not to mention having Dumbledore by his side.

Based on their years of friendship, Professor Sgrughorn completely trusted Dumbledore, and there was a high chance that he would be allowed to access his memory.

If you meet some wizards with strong logic and proficiency in [Occlumency], they can find clues through reasoning, and then use their consciousness to encourage their subconscious mind to restore the memory to the subconscious mind.

It's a pity that almost every potions master is a logic master.

Memory is a magical existence.

It is in consciousness, on the surface of the soul, in the body.

There are many places to store it, and it is difficult to delete all memories including traces in each container when deleting memory.

Therefore, Voldemort chose the delicate task of modifying memory.

He is not like some fools in the "Memory Deletion Command of the Department of Magical Accidents and Disasters" who only know how to change things abruptly.

Of course, if the object of memory modification was a Muggle, Voldemort would probably modify it as roughly as he thought the fool would.

However, Voldemort generally does not modify the memory of Muggles, but sends a [Killing Curse]. The disappearance of life is a beautiful scenery to him, except for himself.

Due to cognitive differences, Muggles at this stage do not know that human memory can be modified.

Therefore, when they notice that their memories are a little strange, they don't think about it. Even if they think about it, they won't talk about it, because doing so will be considered a lunatic.

Wizards are different. Anyone who goes to school seriously will know the existence of the [Forgetting Curse], especially those students who intend to apply for the Department of Legal Enforcement of the Ministry of Magic.

Therefore, once a wizard realizes that something is wrong with his memory, their first or second reaction should be that someone has used memory magic on them.

When modifying Professor Sglughorn's memory, Voldemort was also thankful that it was just the two of them at that time, otherwise it would have been really difficult.

The memories involving Professor Sgrughorn himself were compiled by guiding the other person's memory, just like a dream.

We appear in an inexplicable and bizarre scene, but we don't feel strange at all. We still retain our own habits, do what we need to do in our dreams, and even have wonderful psychological activities.

Voldemort's memory modification is similar to this.

He was equivalent to turning that real memory into a dream, then modified some important contents in it, and then put his own and Professor Sgrughorn's consciousness into it.

Under his guidance, the plot gradually moves in the direction he needs.

Finally it ends, replacing the memory of the past.

Will this be found out?

Yes, but Voldemort can guarantee that Professor Sgrahorn will never be bored enough to experience every memory of his.

This is a huge project.

As masters of memory magic, they also have a crude method to check whether there is something wrong with their memory and restore it.

They call this method "memory flushing."

As the name suggests, the method is to mobilize all the memories you can mobilize and go in and experience it quickly.

This is to flush one's consciousness with memories. Every memory stored will leave traces on the consciousness, the surface of the soul and the body.

Use memory flushing, and those traces will emerge, and erroneous memories can be corrected.

However, few people use this method.

The predecessors of wizards have already conducted relevant experiments, which will lead to problems with consciousness, brain damage, and the most unacceptable damage to the soul.

St. Mungo's Hospital for Magical Maladies and Maladies, in Professor Sgrughorn's ward.

"What's wrong, Horace? Are you feeling uncomfortable somewhere? Do you want me to call a doctor for you?"

Professor Flitwick asked, looking at Professor Slughorn who looked a little strange.

After receiving the news of Professor Sgrughorn's attack, the professors at Hogwarts immediately took action.

Together they came to Professor Sgrahorn's ward.

Professor Flitwick was then left with Professor Slughorn.

Other professors went to attend a trial.

It was initiated by the Auror Command of the Department of Legal Enforcement of the Ministry of Magic, and the target was Professor José Grahorn's friend, on suspicion of murdering the Dean and Professor of Hogwarts.

However, there are still people left behind at Hogwarts.

Hagrid, Filch and Madam Pomfrey were left in the shop in Hogsmeade to look after the store, with the new Professor Twining Woods following them to prevent any accidents.

Hogwarts was temporarily handed over to the care of the Forbidden Forest.

Originally, Grindelwald wanted to follow him and join in the fun, but was suppressed by Dumbledore's calm eyes.

"It's okay, Filius, I always feel like I'm missing something."

Professor Sgrughorn said with some sadness that he felt that he was indeed missing something, but he didn't know what it was.

"Call the doctor to come and take a look. It's a pity that Poppy isn't here, otherwise we could just ask her to come."

Professor Flitwick suggested.

"Huh? Let's forget it. Okay, let them take a look."

Professor Sgrughorn originally thought about refusing, but when he heard Professor Flitwick say Madam Pomfrey's name, he immediately changed his mind.

After speaking, he knocked on the small bell on the bedside, and the bell rang for a while.

After a while, the doctor came over.

Professor Flitwick told her the matter, and the doctor nodded, asked Professor Sgrughorn again, and after confirming that everything was correct, began the examination.

After several inspections, there was nothing wrong.

The doctor told him that it might be a leftover problem after being frightened by the attack, and that he would be fine after a few days of rest.

After giving Professor Sgrahorn a few words of advice, the doctor left.

Professor Flitwick and Professor Slughorn looked at each other, and both saw the speechlessness in the other's eyes.

"What do you think? Horace."

Professor Flitwick asked.

"No. There must be something wrong, but I don't know where it is."

Professor Sgrughorn frowned, his big belly bulging out.

"Would you like to try wand divination?"

Professor Flitwick said.

"Wand divination? Did you find anything else while we were gone?"

Dumbledore's voice came from the door, and the two of them looked to see that Professor Sgrughorn's friend was also there.

"Why are you back so soon?"

Professor Flitwick was surprised and told them what happened.

Everyone looked enlightened, except Sgraho

Professor En's friends are different.

He looked at Professor Sgrughorn on the hospital bed with a guilty look on his face.

"Holden, I'm fine, don't worry."

On the contrary, it was Professor Sgrughorn who spoke first to comfort him.

"I'm very sorry, Horace, I didn't know they were so rampant... I originally wanted to talk to you about the potion, who knew..."

Holden Greengrass said with a guilty face.

"It's okay, am I fine? Did the previous potion have an effect?"

Professor Sgrughorn comforted himself and changed the subject.

He knew the reason why Holden asked him out. This was not the first time.

The Greengrass family is burdened with a curse. In every generation of witches, one must be born with the curse of "Blood Curse".
