A day at Hogwarts

Charles suddenly found that Snape looked at him with a strange and scary look during class, and wondered if he had been discovered when he anonymously sent him shampoo last Christmas.

But there was no reason to be discovered. He placed an order to Seamus' mother and then shipped it directly at the Owl Post Office in Diagon Alley. If he was discovered, Seamus would be suspected first.

Charles finally decided to ignore it. If he had the guts, he would kill himself.

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

Obviously, he knew who was going to come.

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

Charles said: "Professor, I want to ask about the change of metal properties after the alchemy potion expires."

He conducted several short-term experiments before the holiday last school year, and asked Dobby to arrange daily measurements by the part-time elf.

Dobby sent the measurement results last night. From the data, it can be seen that the data of many materials did not return to the state before the experiment after the 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 studied 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, and some people believe that long-term magic will cause the material to change more than once, just like roasting raw meat and then burning it. Some people think that the first two views are correct and are carried out at the same time."

"Now some people are starting to study the second view, but it will take a long time, and I am afraid there will not be many results in a short time."

"I discovered the second view before."

"In alchemical changes, the changes and potions are not a single substance, and multiple ingredients affect the final result."

"If the time is too long, a certain component that affects the change disappears or becomes a by-product and no longer plays its original role, then the change reaction it previously suppressed will proceed, so new characteristics will appear."

"Or, the by-product itself causes new changes, or promotes some originally negligible changes."

Charles nodded, it makes sense.

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

"Later, I experimented several times and finally determined that it was the problem of the salamander blood in the materials."

"At that time, the salamander blood in the medicine cabinet came from two places. The salamanders in one place were fed with mice, and the salamanders in the other place were fed with chickens, which led to different components in the blood and different results in the alchemical experiments."

"It's just that this change in characteristics is not what others want, so they all ignore it. I discovered the problem because I needed this characteristic."

Charles thought it made sense.

Erica had said before that a long time ago, a student at Durmstrang accidentally invented a potion. It failed when it was made for the second time. Finally, it was found that drinking two bottles of beer before making the potion would succeed.

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

Charles thought and said, "It seems that I need a laboratory for such long-term experiments."

When he used the time converter in his first year, he was assigned a room, which was not taken back later and is now a gym.

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

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 shuddered 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".

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 beat someone to death in the first grade? If it was the son of the Dark Lord, it would make sense.

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

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

Logically speaking, if there were outsiders, Charles would not kill people, right?

Even if he was unwilling in his heart, Malfoy had to bite his teeth and compromise for his own life.

Ten minutes before eight, Hermione came out of the library holding a pile of books, with only her eyes showing.

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

"Miss Granger," he said 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 diet and lose weight, or Snape wanted to wash his hair. Hermione, Harry, and Ron were stunned for several seconds.

Hermione frowned, and suddenly thought of something, whispering: "Charles, Polyjuice Potion can't be used indiscriminately, if you get caught, you will be put in detention!"

Harry and Ron suddenly realized, because they had done this before, so they didn't doubt Hermione's words.

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

"Lend me the camera, I'm going to take a picture of his embarrassment and send it 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 finished speaking, 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. He felt pain in his chest every time he breathed.

Harry looked at his fist with four eyes. Why did he fall down before he even exerted any strength?

Several Slytherin students passing by whispered.

"What's going on?"

"Malfoy actually went to chat up Granger?"

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

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

"You didn't know it in your first year, but you'll understand it after a while. Smith treats them as children."

"I don't dare to imagine how Smith will react."

"But did you notice that Granger is also very beautiful."

"Hey, Smith is here."

Charles found several Slytherin students in the corridor looking at him strangely. He thought it was because of Greengrass and didn't care.

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

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

"Charles, Malfoy wants to pick up Hermione!"

Then Harry's group and the Slytherin students who came back to watch the fun saw Charles dragging Malfoy away.

Charles dragged Malfoy to an empty classroom nearby, closed the door, took out a check and said, "Put aside what happened just now, why is this check returned to me?"

This was a check for 10,000 Galleons that he had exchanged for Malfoy during the summer vacation. The money had arrived, but this unredeemed check was sent to the Centaur Liaison Office by 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?

After seeing the check, Malfoy opened his mouth and lowered his head and said, "I was targeted, kidnapped by... by... I don't know who, tortured and interrogated many things, and this check was taken away by him."

"Sorry, he gave me a lot of truth serum, and I told you the truth."

Charles frowned, could it be that Gringotts was warning him?

He asked Malfoy, "Do you know who kidnapped you?"

Malfoy hesitated for a moment, and finally nodded and said, "It was Sirius Black."

"When Black's mother Walburga Black died, my mother went to take care of the funeral. At that time, I went to the Black family's ancestral home at No. 12 Grimmauld Place and recognized the dungeon."

Charles was stunned for a moment. What was going on?

He put this question aside first and asked Black when he had time, and then asked Malfoy, "Then you used your own money to fill this hole?"

"You didn't do anything illegal, right? Those weren't stolen money, right?"

Charles was a little worried that Malfoy would commit a crime to fill the hole, and if the case was discovered, it would be found on his head.

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

Charles blinked, he was selling the Lestrange family's things to fill the hole.

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