Dumbledore? He knows nothing about MC alchemy.

Because of Snape's behavior of adding points, it can be said that the scores of the four major colleges are a bit inflated, so to be honest, it is hard to tell whether the 20 points are serious or not.

Poor Professor Kaisen had to go to the library late at night to look up information to see what kind of confinement to be used for Draco tomorrow, such as...severe or not?

An hour later, Kaisen returned to the office, placed a cubic meter of red stone in the corner, and took out a small file.

He had already made up his mind that Draco would not go back until he had rubbed the entire piece of redstone into fine redstone powder tomorrow.

The next day, evening.

"Professor Kaisen, are you kidding?" Draco held a small file in his hand that was not much thicker than his finger, looked at the red stone in front of him that looked heavier than him, and looked at Kaisen in confusion.

"That's right, Mr. Malfoy. Otherwise, why would you come to detention? You should know that detention is not comfortable."

Draco squatted down resignedly and began to rub with the file.

"...Professor, is this the redstone?"

"You know red stone? You're only in the first grade."

"This thing is very famous in the castle, and the fifth years are showing it off everywhere." Draco complained.

"uh-huh."

"Professor, do you usually use this redstone to create alchemical artifacts?"

"Also, its powder can be used as a magic circuit, which is two different methods from the magic pattern circuit."

"What's the difference?"

Kaisen knocked on the table: "You are here for detention, not for class."

"Okay." Draco lowered his head dejectedly. After about a minute or two, Kaisen's voice came again.

"Normally, the magic power contained in the magic pattern circuit will become magic after the magic pattern is run. However, this can be done with an enchantment table. You should know about enchantment tables, right?"

"Yeah. I know."

"The redstone circuit is the counterpart of the magic circuit. It acts like a switch, used to activate the magic pattern circuit."

Draco nodded: "Then what is the difference between this thing and the magic circuit."

"Faster, stronger, harder."

"what?"

"Keep grinding."

Kaisen sat in his seat, reading a book, and said, "Please hurry, Mr. Malfoy. Your detention is based on redstone. If you only polish this one redstone in seven days, do you know what it means?"

Draco suddenly felt a chill on his back.

"That means you still have six redstone blocks of the same size to grind." Kaisen said to himself without waiting for Draco to answer.

"Oh my God... Professor, you wouldn't be so cruel, would you?"

"........................"

"You wouldn't be so cruel, would you?" Draco couldn't help but speed up the process of filing the redstone.

Chapter 48 He Almost Believed It

Redstone has a soft texture, and the sound of grinding it with a file is not that harsh. If you close the door, it can barely serve as white noise for sleeping at night.

This went on until the middle of the night, when Kaisen sat up from the bed due to thirst, picked up a glass of water and drank it all in a daze. After thinking it over, he walked out of the bedroom.

Draco was kneeling in the corner of the office, a file in his hand, leaning against the wall and already asleep.

Seeing this, he returned to the bedroom, took out a blanket, and carefully covered Draco with it, but still had no intention of preparing a bed for him or letting him return to the dormitory.

People should always pay a price for their actions. Draco didn't know how hurtful a vicious word could be, so as a professor, Kaisen kindly helped Draco understand how heavy the price of his actions was.

And so the next day...

Draco felt the sunlight shining on his face and opened his eyes in confusion.

He expressed deep respect for the nightmare he had last night. There was no blood, no darkness, no sudden faces. Just a huge red stone and a file could make him feel that deep fear.

But fortunately, the dream is over.

He subconsciously wanted to stretch, and then he felt his body stiffen. He looked down... the redstone... which he had been grinding for half the night was only two-thirds left.

The small file is still in his hand.

"............................"

He stood up, and the blanket he was wearing slipped to the ground. He kicked the red stone in front of him with some frustration, but unfortunately, although the red stone was soft, it was only soft compared to stone.

Compared to Draco's feet......

"what!!!!"

He subconsciously stepped back, and one of his feet stepped on the blanket, and the other foot was tripped by the blanket. The forces in the two directions interacted with each other, and then he fell straight backwards.

The back of my head hit the ground hard, but fortunately there was a thick wool carpet.

A series of bad luck and the frustration of grinding redstone all night yesterday piled up together, making Draco break down and cry.

Kaisen, holding a stack of stimulants, stopped outside the office door and put his ear to the door to listen.

He waited until the noise inside died down a little before he opened the door and walked in.

"Drink this bottle of refreshing potion, otherwise you will probably catch a cold if you stay here all night." Kaisen placed the refreshing potion on the coffee table, along with a sandwich and a bottle of pumpkin juice.

"Oh, and breakfast."

Draco, who had been grinding redstone all night, was already starving. He picked up the sandwich and took a bite. When he tried to swallow it, he found that his throat was sore.

He has caught a cold.

"Depending on your progress...it will take about twenty-one days to get out of confinement." Kaisen looked at the degree of wear of the redstone, touched his chin and sat on the sofa, opposite Draco.

He looked at the little wizard in front of him with a look of fear and resentment and shrugged his shoulders without any other thoughts. It was like a prisoner hating his jailer, which was human nature.

But an explanation is still needed.

"Did you regret it later?"

"What?" Draco, who was eating in pain, raised his head and asked.

"Do you regret using such foul language to insult Miss Granger?"

Draco didn't answer, but continued eating with his head down.

"Do you know what mudblood means........?"

Draco shook his head.

"That's right. Your parents might occasionally say such words, but they would never teach them to you. In short, this word is very dirty. It is definitely not an ordinary derogatory term for Muggle-born wizards."

"You can use any word you can imagine, including but not limited to genitalia, animals, personal insults, humiliation, curse words, and none of them combined together are as vicious as the original meaning of the word."

"I know." Draco lowered his head and said dryly. Kaisen didn't know whether he knew it or not.

"Remember to drink this refreshing potion after you finish eating. I have prepared fourteen bottles of refreshing potion for you, but considering your efficiency, I need to go to Madam Pomfrey to get seven more bottles... In other words, you will have to endure this kind of life for another twenty days."

Hearing Kaisen's cold words, Draco's tears, which he had held back with great difficulty, burst out again. The originally sweet sandwich turned salty in less than five seconds.

"I hope you can remember this lesson, Mr. Malfoy. After dinner and taking medicine, you can wash up here, or you can go back to your dormitory, wash up, and then go back to the classroom for class. After class in the afternoon, after you finish the labor assigned by Professor McGonagall, come back here until you have finished grinding seven red stones."

Draco listened with trembling eyes, and raised his head with a bit of grievance: "Can I take a leave and stay here all the time?"

"In this way, other young wizards will learn many more spells than you, and you don't want to be beaten without any chance to fight back in the next wizard duel or fight." Kaisen did not refuse, but explained the pros and cons clearly.

"I'll be back after class."

"Of course, if you don't come I'll have to go to Severus myself and ask for him."

After Draco left the office, Kaisen waved his hand and collected all the redstone powder scattered in the corner, which could be used directly as teaching materials for the fifth grade.

Soon, the first-year morning classes were almost over, and Draco returned to the alchemy office dejectedly and picked up the small file to sharpen it.

Kaisen continued to sit on the sofa as if he didn't see anything and made a pot of green tea.

When it was time for class in the afternoon, Draco would leave in shame again. In this way, in just half a day, another one-third of the redstone was erased.

Kaisen was quite satisfied with this. After all, if he continued to maintain this efficiency and speed, he might not need to go to Madam Pomfrey to get another stack of stimulating potions.

Of course, redstone is secondary. He still sincerely hopes that this little wizard who speaks without thinking can learn from this lesson.

After all, he is only eleven years old, and the little Laozi has not yet been fixed as the father, so everything is still in time.

In this way, the naive Professor Kaisen thought everything was moving in the right direction.

Especially one day a week and a half later, when Draco had only the last piece of red stone left.

If the four little Gryffindors hadn't come, he would have almost believed it.

Really.

Chapter 49 Why didn’t you say so earlier?

"Wait, wait, wait... repeat it to me again..."

Kaisen took a deep breath and said slowly, "Draco was in the office first, grinding the red stone honestly, right?"

Draco, who was standing in the corner dropping pearls, and the four Gryffindors beside him nodded at the same time.

"Then, the four of you came to see me. My office door happened to be unlocked, and Draco just happened to say 'come in,' and you came in."

The five little wizards nodded again.

"Then, after you came in, Draco was still obediently grinding the red stone, and Ron, you were sitting there drinking Coke...wasn't the Coke you found there? Never mind, this is not the time to be fussy about that. Anyway, Draco didn't provoke you, and then Ron was sitting on the sofa drinking Coke and talking nonsense."

"Finally, you made Draco angry and you both pulled out your wands and started fighting."

The five people still nodded.

Kaisen nodded in understanding. "I almost understand... If that's the case... why don't you... go out and fight? Like you said, my office door isn't locked. Aren't you afraid you won't be able to get in after you're done?"

"Um... I'm afraid the professor and Filch will find out if I go out to fight," Harry said in a low voice.

"...Harry, I ask you, who am I?" Kaisen sat on the only surviving sofa in the corner, pressing his thumb on his philtrum, and said without any strength or skill.

"Are you Kaisen... or Professor of Alchemy?" Harry said the first answer without thinking at all, and then he realized... Professor Kaisen in front of him... the last two words are Professor.
