Dumbledore? He knows nothing about MC alchemy.

As he expected, the four little ones gathered around him curiously.

"Why doesn't this alchemy rely on magic patterns?" Hermione asked curiously.

"Have you heard of the enchantment table? I like to use the enchantment effect of the enchantment table to replace the work of magic patterns. It is more stable and more durable." Kaisen explained while dismantling the redstone lamp.

"What are these red threads?"

Hermione asked again.

Kaisen was very satisfied with Hermione, the supporting actress, and a red stone appeared in his hand.

"This is an alchemical substance I refined myself. I call it redstone. It's a crystal of magical energy that can replace the function of a magic circuit to a certain extent."

"The problem with this redstone lamp is very simple. The redstone circuit is broken. This is also one point that redstone circuits are more advanced than simple magic circuits. If it were a magic lamp, it would have exploded long ago." Kaisen said with a smile.

"Is there any way to fix this lamp?" Ron leaned over and asked.

"Yeah, it's very simple. Just find the broken part and reconnect it."

"As long as I touch the redstone circuit with redstone, the redstone circuit will light up. Sometimes when the circuit of a large redstone mechanism I made is wrong, such as a very complicated switch, when I am too lazy to open it in sequence, I will just remove the shell."

"Then like this." Kaisen directly attached a small piece of redstone to a redstone circuit closest to the redstone light emitter.

"Wouldn't this kind of redstone alchemy be very easy to destroy?" Hermione asked.

“Use the shell.”

"Oh...that's right." Hermione said a little embarrassedly.

"Hmm." Kaisen quickly repaired the redstone lamp he had just destroyed before looking at the few people.

"I suppose you have good news for me?"

Speaking of this, Neville immediately became excited.

"During flying class today, that Malfoy didn't learn his lesson and tried to cause trouble for me. I gave him a good lesson. He put my Remembrall on a tree, so I put his on a tree too!"

As Neville spoke, his face flushed red and he was extremely excited, like a brave man who had defeated a big dragon.

"That's great, and I can see that you've regained your confidence. Believe me, your grandma will be surprised by your change when you go home for Christmas." Kaisen said with a smile.

"Will she?" Neville asked with a twinkle in his eye.

"Yes." Kaisen answered without saying anything, and at the same time secretly made up his mind that it was necessary to write a letter to Neville's grandmother.

It is not advisable to suppress education blindly.

"Also, Harry successfully joined the Quidditch team. He's the youngest since the school was founded, and Professor McGonagall personally approved it!"

Neville then continued sharing with Kaisen, and it seemed as if he could talk for ten days or half a month.

It was not until the sun began to turn yellow that the four people realized that they had stayed here long enough and it was time to leave.

"By the way, I have a small gift for you. I hope you don't mind. Maybe you can use this thing to make some interesting little things." Kaisen waved his hand, and four fist-sized redstone cubes appeared on the coffee table in front of him.

"Thank you, Professor!" ×4

"Let's go. It may sound a bit greasy to say this, but study hard."

Kaisen stretched his muscles, left the office and walked towards the auditorium.

I heard that there are lamb chops for dinner tonight, I must try them.

Not all professors may come to breakfast, lunch, and dinner every day. Most of the time, all professors will only attend on occasions such as the opening dinner and Halloween dinner.

It was a rare occasion for Kaisen to see Professor Snape, who usually seemed invisible, sitting in the professor's chair on ordinary days.

"Good night, Severus... perhaps this greeting is a little strange."

Snape shook his head: "I've seen weirder greetings..."

As he spoke, he looked up at the professors' chairs to make sure no one noticed them. There was also the empty seat belonging to Quirrell. After thinking for a moment, he said, "Dumbledore told you about Quirrell?"

"Well... not really. I discovered it myself." Kaisen replied.

Snape nodded. "Very perceptive. The other day I went to Hogsmeade to buy some potion ingredients. I saw you and Hagrid drunk at the Hog's Head. There was also a man in black who seemed to be trying to trick you. Who was that man?"

"I can't see his face clearly, but I think it's Quirrell, asking Hagrid how to get through his three-headed dog and my piston door... Did he ask you?"

"No, if he still needs to come to me for questions like that, he should go to St. Mungo's to check his brain." Snape's words did not hide his contempt for Quirrell at all.

"Yeah, uh..." Kaisen agreed and suddenly paused.

"Dumbledore trusts me. He also told me that if necessary, I should give Quirrell a push, which means telling him the right option." Snape noticed Kaisen's pause and explained.

"I don't have any opinion about Quirrell, or Voldemort. He's nothing more than a powerful and evil dark wizard. It's just that Dumbledore always believes in that prophecy. I'm a newbie here. Seriously, does he really want to rely on a child like Harry to defeat Voldemort?"

"Prophecy...sometimes it does require awe."

"Um..." Kaisen didn't know how to continue the conversation, so he could only say dryly, "I always thought potions was a materialistic subject."

"That's not the case." Snape was about to explain when he was interrupted by a commotion in the student seats below.

Chapter 26 I need music! Thief class!

"What's going on down there?" Kaisen asked curiously.

"The midnight duel between Slytherin and Gryffindor was nothing to watch," Snape said coldly.

Only then did Kaisen look towards the source of the noisy sound, but unfortunately he was too far away to hear what was said.

And both sides are familiar with each other, including Harry, Neville, Ron and Hermione, four young Gryffindor wizards.

When listening to Harry and Neville chatting before, Kaisen thought that their relationship with Hermione was not very good. It seemed that the relationship between them improved after Hermione helped Neville and gave him advice in her office that day.

The Slytherin wizards on the other side were also familiar faces. The leader was Draco Malfoy, but he didn't know the other two.

But speaking of it, Draco Malfoy's father, Lucius Malfoy, seems to be full of the upper-class restraint and alienation, but his son is full of publicity and domineering.

Honestly, if it weren't for the fact that their bone structure and hair were almost identical, he would have doubted...

You can't doubt it, it's impolite to doubt it anymore.

"Is there no one to stop them?" Kaisen asked Snape who was standing beside him.

"You can, but you don't have to. Slytherin and Gryffindor have been fighting each other for so many years. There's no need to worry about such trivial matters. At most, they are just a little nosy."

"Nosy?"

"The Squib."

"...Mr. Filch? He's a Squib?"

"He's still a Squib who refuses to accept his fate. Most of the salary Dumbledore has given him over the years has been given to a series of con men who target wealthy Squibs." Snape gave a rare explanation.

"I understand." Kaisen nodded. The farce at the dinner party did not cause any waves.

Just as he finished dinner and was about to return to his office, Snape suddenly spoke.

"By the way, you and I are going to that corridor later. I have already prepared the harmless potion you mentioned last time. It is some water of life and death that can be effective through air and skin contact, but I still need to put it into your alchemical creation."

"No problem, now?"

"Right now."

The two left the auditorium and walked directly towards the corridor.

It wasn't until the two of them walked outside the empty classroom that a record player suddenly appeared in Kaisen's hand, and a stack of records in his other hand, like an opened deck of cards, from which he was selecting.

"What are you doing?"

"Hagrid said that if we just give this three-headed dog some music, he'll fall asleep. I'm choosing."

"There's no need for that." Snape shook his head, took out his wand and walked in.

"It's nothing more than a beast, all it takes is a faint..."

"what!"

"I need music! Trickster class! Trickster class!" [music]

The corners of Kaisen's mouth twitched uncontrollably, and he no longer cared about the record player and records in his hand. A piece of obsidian flew out of his hand, split into three in the air, and smashed heavily on the three heads of the three-headed dog.

"Hiss... This beast bites so quickly." Snape lifted up his trouser leg and looked at the bloody wound on his calf.

"You are too careless." Kaisen was understanding and helped Snape to say the excuse that he was embarrassed to say.

"Excuse me, help me a little."

"Of course." Kaisen reached out and supported Snape's shoulder, while the latter took out a bottle of bright red potion from his pocket and poured it directly on the wound on his calf.

"Are there any bandages or anything?"

"Well, I think it should be about the same. This thing, but it's not sterilized." Kaisen took out a large piece of wool, rolled it up, and pulled it.

"It's okay." Snape took it and took out the potion and sprinkled it on.

"more or less."

Snape nodded, bent down and bandaged the wound, and then the two of them fought their way through to the last level.

This also once again confirms the value of Hagrid's level arrangement.

The other professors, including Kaisen, were there to help Quirrell, Harry and the others pass the levels for fun.

Only Hagrid aimed to kill the invaders.

Otherwise, he is honest.

The two of them loaded the potions into the launcher. In the middle of the process, Kaisen picked up a bottle of potion and looked at it curiously.

"This potion?"

"The real deal."

"Okay, although our potion this time may not be useful."

"We can recycle it later. Let's go."

The two returned to the empty classroom containing the three-headed dog. Kaisen tentatively took out a feather to test the big dog's breath.

Because I wasn't sure if this big guy had three sets of lungs, I tried all three heads.

I breathed a sigh of relief when I confirmed that everyone survived.

After all, Hagrid loves magical creatures so much, he will definitely be very sad if this big guy dies.
