The wizard in Hogwarts is unscientific

Andy did a math problem.

The time converter can only go back to the 'whole hour' ago. If you want to use the time converter to go back to a precise point in time, you must use the time converter twice.

For example:

It's eight o'clock sharp now, but Andy wants to go back to six-thirty.

Then Andy needs to use the time converter to return to seven o'clock at eight o'clock.

Then wait until half past seven, and use the time converter again, so that you can accurately return to half past six.

"Well……"

Andy pondered for a moment.

At present, the method is already available, and the spatial coordinates are already available - Andy is eight-level sure that the book recording the time reversal spell must be hidden in the data storage room of the Department of Mysteries.

"But the time coordinates..." Andy was a little troubled.

Can the Department of Mysteries uncover this clue?

Andy wasn't sure.

But for now, Andy can only go to the Department of Mysteries to look for clues.

Time magic, Andy doesn't want to give up.

…

Charms class is over, and the next class is Defense Against the Dark Arts.

The professor for this class is Remus Lupin, one of the legendary Gryffindor F4s.

I have to say that Professor Lupine's class is still very good, which also makes Andy relieved - at least this year he doesn't have to expel the Defense Against the Dark Arts professor.

By the time the Defense Against the Dark Arts class ended, lunch time was almost here.

"Hermione, you go to the auditorium first. I have something to do with Professor Snape," Andy said.

"Okay! Then I'll wait for you in the auditorium." Hermione nodded and walked towards the auditorium.

Andy came to the door of Snape's office, stepped forward and knocked lightly.

Dong Dong...

Andy only knocked twice before the door to Snape's office opened by itself.

"Professor Snape, good afternoon." Andy walked into the room and closed the office door with his backhand.

Snape's attitude was as bad as ever. He stared at Andy covertly and said slowly: "Collins... I don't know what happened between you and Malfoy. But... some things are best not to be let go." He’s involved.”

"Oh?" Andy raised his eyebrows.

Snape frowned and said in a somewhat impatient tone, "Malfoy has no palace and no abilities. He will expose your secrets."

Andy found a chair and sat down. After hearing this, he said casually: "If you investigated more carefully, you should know that it was Malfoy who came to see me last night."

"besides……"

Andy looked at Snape and said pointedly: "I thought you would care more about Harry."

Snape's face darkened.

Of course he cared more about Harry.

But Harry himself is already very dangerous, that is Voldemort's target. Hanging out with Andy would only make Harry's safety more secure.

And Snape knew Harry, and Harry would never get involved in Andy's private affairs.

This has nothing to do with friendship, but personal belief.

And when Andy gets along with Harry, he will never reveal his true face.

But Malfoy was different.

Snape felt that Malfoy was just a fool, and as long as Andy said a few words, the child would work hard for Andy.

"What does he want from you?" Snape asked.

"You should ask Malfoy."

Andy replied casually, and then said bluntly: "Professor Snape, the Resurrection Stone... can you return it to me?"

Snape stared at Andy for a long time, then took out the Resurrection Stone from his pocket and threw it to Andy.

He really needed to talk to Malfoy.

Andy Collins...this man is so dangerous.

Malfoy would be eaten to pieces if he came into contact with him.

"If you need it in the future, you can always come to me."

Andy looked at Snape and suddenly asked: "Professor, when do you plan to visit the Department of Mysteries?"

Snape: "..."

"That has nothing to do with you." Snape said coldly.

"Don't be so absolute."

Andy smiled and said: "I am very interested in all magic, and I think I have some talent. Resurrection magic... is also among my research topics, and I already have some ideas."

Snape looked at Andy with cold eyes. He did not answer the question, but took out a manuscript from the drawer.

"This is the analysis report of the green liquid."

Snape looked at Andy, "You seem to have forgotten it?"

Andy spread his hands and said with a distressed look: "I really forgot! There have been a lot of things recently, and those green liquids were always handy... Oh~ thank you!"

After speaking, Andy took the manuscript and opened it for a quick glance.

There were a lot of professional terms in the manuscript, and it was obvious that Snape was deliberately trying to embarrass Andy.

Fortunately, Andy understands.

"...maintain brain activity?"

Andy glanced quickly, and then looked at Snape with an expression of "Are you kidding me?" "Even if I don't test it, I know that those green liquids can maintain the activity of the brain."

After all, that's the kind of fluid those brains are soaked in.

Snape's manuscript is quite comprehensive. He has roughly detected the components of the liquids, but in terms of the effect of the liquids... it only has the function of 'maintaining brain activity'.

"You gave me too few samples."

Snape's tone was not very good, "If you want to experiment with other effects of those green liquids, you must go through a lot of experiments."

Ah this...?

The truth is indeed this truth, Andy understands it!

"I thought you could analyze the effects of liquids from their components."

Andy gave an example, "Just like the pharmacology of potion ingredients, haven't you studied it thoroughly?"

Snape: "..."

"Those liquids are not magic potions. There are many other ingredients in them. Because the samples are too small, they cannot be analyzed for the time being." Snape explained.

OK!

Andy's original purpose was not to study those liquids.

What interested Andy was those brains.

"In other words, just soaking human brains in these green liquids can maintain their activity?"

Andy asked curiously: "Can those brains still think like normal people?"

When it came to academic issues, Snape's attitude became much more serious, "I'm afraid not! The brain itself has no perception. The brain soaked in it should have been modified. That modification gave the brain a certain perception. .”

"I guess the Hall of Brains is for studying the organ that stores the soul...that is, the brain."

Having said this, Snape clicked on the location of the brains, and then continued: "But those brains should only have the most basic abilities left - that is, the instincts of the brain."

"Brain instinct?" Andy thought thoughtfully.

Snape said: "Souls... they are more mysterious than you think."
