A day at Hogwarts.

Chapter 439 What is going on?
Charles suddenly realized that Snape looked at him with a strange and scary look during class, and wondered if the shampoo he anonymously gave him last Christmas was discovered.

But there was no reason for him to be discovered. He placed the order with Seamus' mother and then shipped it directly through the Owl Office in Diagon Alley. If he were discovered, they would probably suspect Seamus first.

Charles finally decided to give up and kill himself if he had the guts.

After dinner that day, Charles came to the alchemy professor's office and found Professor Delacour carefully adjusting the interior decoration.

Clearly, he knew who was coming.

Professor Delacour asked Charles, "What's the matter?"

Charles said, "Professor, I would like to ask you about the change in the properties of metals after the alchemical potion loses its effect."

He had conducted several shorter experiments before the holidays last school year, and had Dobby arrange for the elves to take daily measurements.

Dobby sent me the measurement results last night. From the data, we can see that many materials did not return to their pre-experimental state after failure, and the resistance of some materials was even lower.

Professor Delacour asked Charles to sit on the sofa, opened the snack box and said, "This is a less researched field, mainly because the alchemists in the past were too focused on the immediate results and lacked long-term research."

"There are many speculations about this phenomenon. Some people believe that some alchemical changes are irreversible, some believe that long-term magic effects will cause the materials to change more than once, just like roasting raw meat and then burning it. Some people believe that the first two views are correct and occur at the same time."

"Some people are beginning to study the second view, but it will take a long time, and I'm afraid there won't be much results in the short term."

"What I found before was the second view."

"In alchemical transformation, the transformed substance and potion are not a single substance. Multiple ingredients affect the final result."

"If the time is too long, a component that affects the change will disappear or become a byproduct and no longer play its original role, then the change reaction that it previously inhibited will proceed, so new characteristics will appear."

"Or the byproducts themselves cause new changes, or they promote some kind of change that was originally very small."

Charles nodded. That made sense.

Professor Delacour continued, "I discovered this problem because the results of two alchemical experiments were quite different."

"After several experiments, I finally determined that the problem was the salamander blood in the material."

"The salamander blood in the medicine cabinet at the time came from two places. The salamanders in one place were fed with mice, and the salamanders in another place were fed with chickens. This led to different components in the blood and different results in the alchemy experiment."

"It's just that this changing feature is not what others want, so they ignore it. I discovered the problem because I needed this feature."

Charles thought it made sense.

Erica told me before that a long time ago, a student at Durmstrang accidentally invented a potion, but failed the second time he made it. Finally, he found out that he had to drink two bottles of beer before making the potion in order to succeed.

Grindelwald admitted that this was true, and that drinking wine would not work, only beer was needed.

Charles thought for a while and said, "It seems that I need a laboratory to do this kind of long-term experiment."

He was assigned a room when he used the time-turner in first grade, but it was never taken back and is now a gym.

Charles looked at his watch, and as he had an appointment with Malfoy tonight, he said goodbye to Professor Delacour.

In front of the library, Malfoy paced back and forth in the corridor anxiously.

He thought to himself, Charles asked him to come here only to exchange Galleons during the summer vacation, could there be something wrong?

Malfoy couldn't help but shudder when he thought of this. He was almost beaten to death for offending Charles that year. If something went wrong this time, there would probably be no "almost" anymore.

He remembered another thing. In the afternoon, Pansy said mysteriously that Charles might be the son of the Dark Lord.

This made Malfoy suddenly enlightened. What kind of person would almost kill someone in his first year? It would make sense if he was the Dark Lord's son.

Let’s put this matter aside for now, the next thing is the most important.

Malfoy kept thinking about how to save his life, when suddenly his eyes lit up and the Dark Lord's grandchildren, Harry and Hermione, came over, followed by a red-haired idiot.

Logically speaking, if there were outsiders present, Charles wouldn't kill anyone, right?

Even though he was extremely unwilling, Malfoy had to grit his teeth and compromise for the sake of his own life.

Ten minutes to eight, Hermione walked out of the library holding a tall pile of books, with only a pair of eyes showing.

Malfoy rubbed his face, forced out what he thought was a kind smile, and walked over.

"Miss Granger," he tried to act politely, "there are so many books. Do you need me to help you get them?" This was even more incredible than Ruby saying she wanted to go on a diet or Snape saying he wanted to wash his hair. Hermione, Harry and Ron were stunned for several seconds.

Hermione frowned, suddenly thinking of something, and whispered, "Charles, Polyjuice Potion cannot be used indiscriminately. If you are caught, you will be put in detention!"

Harry and Ron suddenly understood, because they had done this before, so they did not doubt Hermione's words.

Ron asked excitedly, "Where did you hide Malfoy?"

"Lend me your camera. I'm going to take some photos of his embarrassing appearance and send them to the Daily Prophet."

Harry smiled and said, "What are you going to do? You didn't even call me for such a fun thing!"

After he said that, he punched Malfoy in the chest just like he did when he played with Charles in the past.

Malfoy suddenly felt as if his chest was hit by a carriage. He staggered back a few steps and sat on the ground, feeling pain in his chest with every breath.

Harry looked at his fist with all four eyes. Why did he fall down before he even exerted any strength?
Several passing Slytherin students murmured quietly.

"what happened?"

"Malfoy actually hit on Granger?"

"Granger's brother is here, isn't this asking for trouble?"

"Why do you say Potter is Granger's brother?"

"You don't know it in your first grade, but you will understand it after a while. Smith treats them as children."

"I dread to think how Smith would react."

"But did you notice that Granger is also very pretty?"

"Hey, Smith is here."

Charles noticed several Slytherin students looking at him strangely in the corridor, and thought it was because of Greengrass, so he didn't take it seriously.

He turned a corner and saw Harry and the others, all looking at Malfoy in the corner. They couldn't help but quicken their pace and ask, "What happened?"

Ron turned around and said, "Ah, he's really Malfoy?!"

"Charles, Malfoy wants to pick up Hermione!"

Then Harry and his two companions and the Slytherin students who had returned to watch the fun saw Charles dragging Malfoy away.

Charles dragged Malfoy to a nearby empty classroom, closed the door, took out a check and said, "Putting aside what happened just now, what's the matter with this check being returned to me?"

This was the check for 10,000 Galleons that he had exchanged for Malfoy during the summer vacation. The money had arrived, but the uncashed check was sent to the Centaur Liaison Office using an anonymous letter.

Charles couldn't figure out what this meant.

He was thinking, Malfoy was so poor now, and he gave him 10,000 Galleons for no reason. Where did this money come from? Was it given by Voldemort?
Malfoy opened his mouth after seeing the check, then lowered his head and said, "I was targeted, kidnapped... by... I don't know who it was, and tortured and interrogated about many things. This check was taken away by him."

"Sorry, he gave me a lot of Veritaserum and I spilled you."

Charles frowned. Could it be that Gringotts was warning him?
He asked Malfoy: "Do you know who kidnapped you?"

Malfoy hesitated, then nodded and said, "It's Sirius Black."

"When Black's mother, Walburga Black, died, my mother was in charge of the funeral. At that time, I went to the Black family's ancestral home at 12 Grimmauld Place and recognized the dungeon."

Charles was stunned. What was going on?
He put this question aside for now and asked Black when he had time, then asked Malfoy: "So you used your own money to fill this hole?"

"You didn't do anything illegal, did you? Those aren't stolen money, are they?"

Charles was a little worried that Malfoy would commit a crime to fill the hole, and if the crime was discovered, he would be blamed.

Malfoy shook his head and said, "No, I just sold some of my aunt and uncle's collections."

Charles blinked. He actually sold the Lestrange family's things to fill the hole.

He handed the check to Malfoy and said, "In that case, the check is yours. I return it to you."
