When Sherlock came back from the principal's office, Snape was still standing alone outside the door.

His face was quiet, and on the surface he seemed to have no psychological touch, but his eyes staring at the ceiling were already exposed his uneasy heart.

"Do you think about what to say when you meet again?" Sherlock asked lightly.

Snape didn't go to see him, but just spoke unexpectedly.

"I'll stop seeing her."

Sherlock raised his eyebrows immediately.

"Why are you missing again? Going back to the past few days, aren't you just waiting for this moment? I'm afraid that she knows what you treat Harry? As long as you tell the reason truthfully, you do this to save Harry's life, she will definitely understand."

However, Snape didn't say anything more, but turned around expressionlessly and prepared to leave.

When he and Sherlock passed by, they suddenly said something.

"I owe you."

Sherlock muttered quietly as he looked at his back as he gradually moved away along the corridor.

"Pretty."

In the office, Lily and Harry had just met, so naturally they had countless words to say.

Harry vaguely passed on his own at the Dursleys, and only focused on his experiences after entering Hogwarts.

He said that he knew two friends Ron and Hermione, and the professors in the castle were both very good.

He also talked about his experiences in the past three school years, and talked about the time when he recognized Sirius this year and discovered that Peter was the real traitor. Sherlock calculated that the time was about the same, so he pushed the door and walked into the office.

Seeing Sherlock walk in, Harry immediately introduced Lily excitedly.

"Mom, this is Professor Forrest I told you. He is the best professor in Hogwarts, and he also let me see you."

Lily, who was floating transparently in the air, turned to look at Sherlock, and her beautiful face showed a look of gratitude.

"Thank you for taking care of Harry over the years and letting me see him today."

Lily now maintains her appearance before her death.

It seems to be a little more mature than the Lily she saw when she returned to the past, but the change in appearance is not big.

After all, she and Harry's father James got married as soon as they graduated, and Harry soon after, and when he died, he was the same age as Sherlock now.

Sherlock waved his hand and did not take any credit for this matter.

"I am Harry's teacher, and it's time to take care of him. As for the things you can meet Harry again, you should be thankful to Snape the most. If he hadn't been begging me for the death look, I wouldn't have thought of helping you."

Although the old pretentious person didn't know what to say after meeting Lily, he was in trouble at least, and Sherlock didn't mind saying anything if he could help him.

Not only Lily, but Harry's reaction was much more violent to what he said, and he exclaimed.

"Snape!"

Lily was a smart person during her lifetime, otherwise she would not have won the favor of Slughorn.

"Professor Forrest, you and Snape helped me?"

Hearing her name to Snape, Sherlock couldn't help but sigh in his heart, but this was normal.

Now this Lily has experienced the period when Snape joined the Death Eater and did evil in the magic world. She probably has given up completely with him.

"Simply put, because of some accidents, Snape and I returned to the past. I thought of a way to come back, and he thought of a way to save you. Then I helped him and created a magic based on the development of the subsequent history so that you would not die so thoroughly before you die."

Sherlock's real long story short story, and a few words outlined the matter.

Just after hearing what he said, Lily looked at a place with a daze, and soon guessed the matter.

"That Professor Slughorn is him..."

"On the night of summer vacation, I cried in front of your window and begged him to forgive him."

Sherlock curled his lips and said, "There is nothing to hide." Snape couldn't say it, so he naturally didn't care about it."

Lily's face was a little complicated, making people unable to see her mood at the moment.

"He...and then left the Death Eater?"

"It's useless to persuade him when you are alive, but he repented after he died... Well, it can't be said to have repented, he just figured out something. Then he came to Hogwarts, where he became a professor of Potions and the dean of Slytherin."

As she said that, Sherlock looked at Harry with a meaningful look.

"Of course, because of some relationships, he really didn't treat Harry very well. This professor also thought it was unfair, but it was always much better than the Snape you knew before."

Sherlock said the truth about Snape, without praise or derogatory.

He just said the truth and was already very helpful to Snape. As for what the two of them would say in the future and how to deal with their relationship, these are not something Sherlock should worry about.

Harry was surprised and confused.

He was surprised that Sherlock and Snape disappeared in fact, but he was confused and did not understand what happened about Snape.

He had heard that Snape seemed to have a different relationship with his mother, and he would not know much about the others.

After saying everything he could say, Sherlock reminded Harry and Lily seriously.

"I woke you up, but your current form is still very dangerous, because I have not tried it, and I don't know what kind of spell can affect you, and I don't know how long your state can last. So don't come out of Harry's protective magic every day, it will be almost done in one or two hours. Then I have to hide this matter, and even Ron and Hermione don't tell me."

Of course, Harry wrote down Sherlock's advice with a serious look on his face.

"Thank you, Professor Forrest." He thanked Sherlock very seriously.

But this is certainly not enough for Sherlock to help him do these things. Harry can only keep it in his heart and repay it if he has the chance.

After Harry and Lily left, Sherlock lay relaxed on the chair.

Back to Hogwarts, the important thing made him relax his always tense mood.

But it's just a temporary relaxation.

The moment before the Department of Mysterious Affairs came back, although Voldemort did not cause any harm to him, the overwhelming black mist really shocked Sherlock.

This is the first time he has seen a ceiling-level mission in the magic world take action.

Sherlock didn't know what the black fog was, but when it was surging like a wave beside him, he could clearly feel that even if he could use five hundred, one thousand, or even tens of thousands of spells at one time, he could not break the black fog.

This is no longer something that can be countered by superposition of numbers. The gap between magic and spells is too huge, and no matter how many it is, it cannot be filled.

Thinking about whether Voldemort makes a comeback in the future and now he is messing around in Hogwarts, whether the final outcome can still be as unknown as in the original work.

This made Sherlock even more anxious to strengthen his strength.

There is no shortcut to learn magic. Even if he is diligent and talented, he cannot compare with the decades of magic accumulation like Voldemort and Dumbledore.

But the particularity of time travel finally left Sherlock a way to quickly narrow these gaps.

Let the original owner's dead soul merge with his own soul, and make the soul's origin stronger, and the magic used will naturally become stronger.

And there is also the control magic that comes with the power of the soul. Sherlock always feels that its function is much more than just the control wand cast, and it can also be digged deeper.

To do all this, Voldemort's Horcrux is a must-have.

In other words, for Sherlock, it is like a Great Huan Dan that can increase his strength by 50 years by eating one. He has now eaten one.

He just learned to control the magic without a teacher, and the spell released was much more powerful than before.

Voldemort has definitely more than one Horcrux, which means there are many opportunities left for Sherlock.

Besides, sherlock himself was not sure if he wanted to find the Horcrux. Dumbledore was much more urgent than him.

One of the most important gains of this journey back to the past was that he found clues about one of the Horcruxes.

Rearing on the back of the chair, Sherlock was staring at the ceiling while drinking tea.

Because Lupin's identity was exposed, he could no longer stay in Hogwarts after last night. Sherlock's task, which originally only had to review the final exam results of the sixth grade, has become more serious, and he has to be responsible for the fourth grade of Lupin's substitute.

But he was still not in a hurry, and he didn't know what was going on in his mind. He was stunned for a long time before muttering to himself.

"Where did that little girl Amy go?"

......

The day before Hogwarts officially started the holiday, Shilk sat quietly in front of Dumbledore's principal's office.

Dumbledore looked at the girl with a hood on her head, covering most of her face, and did not hide the confusion in her eyes.

"Why do you suddenly want to teach in Hogwarts? Miss Shilk."

For more than ten years, Shilk has come back to visit Hogwarts every year. Although Dumbledore didn't communicate much with her, she still knew her personality and never thought that one day she would sit in front of her to look for a job.

Shilk said plainly.

"No reason, I just want to change the place."

"Did the German Ministry of Magic agree that you resign?"

Dumbledore's influence was not limited to the United Kingdom, but he had some knowledge of most of the affairs within the Ministry of Magic in Europe, and he was very clear about Hilk's status in the Ministry of Magic in Germany.

Shilk nodded slightly.

"If there are no vacant positions in Hogwarts, I can accept both the substitute and interim professor."

Dumbledore felt increasingly incredible when he heard her say this.
