Hogwarts: I rely on MC to pretend to be an alchemy professor

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

In this way, until the second half of the night, Kaisen sat up from the bed thirsty, picked up a glass of water and drank it all in a daze, and thought about it and walked out of the bedroom.

Draco knelt in the corner of the office with a file in his hand and leaned against the wall and fell asleep.

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

People should always pay a price for what they do. Draco didn't know how hurtful a vicious word was, so as a professor, Kaisen kindly helped Draco understand how heavy the price of his doing so was.

So the next day..............

Draco felt the sunlight shining on his face and opened his eyes a little confused.

He expressed deep respect for the nightmare of last night. There was no blood, no darkness, no sudden face, but only a huge red stone and a file that could make him feel that deep fear.

But fortunately, he woke up from the dream.

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

He still had the small file 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 defense, but it was a pity that although the red stone was soft, it was only compared to stone.

Compared with Draco's feet..............

"Ah!!!!"

He subconsciously stepped back, and one foot 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 just leaned straight from behind.

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

A series of bad luck and the grievances of grinding red stone all night yesterday piled up together, making Draco burst into tears.

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

When the sound inside became quieter, he pushed the door open and walked in.

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

"By the way, there is also breakfast."

Draco, who had been grinding red stone all night, was already hungry. He took a bite of the sandwich and found that his throat hurt when he tried to swallow it.

He had caught a cold.

"Depending on your progress... It will take about 21 more days to get rid of the confinement." Kaisen looked at the degree of wear and tear of the red stone, touched his chin and sat on the sofa, opposite Draco.

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

But the explanation still needs to be explained.

"Do you regret it?"

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

"Do you regret using such dirty words to insult... Miss Granger?"

Draco did not answer, and still lowered his head to eat.

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

Draco shook his head.

"That's right, your father and mother may occasionally say such words, but they will never teach you specifically. 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 genitals, animals, personal insults, humiliation, curses, all of which are not as vicious as the original meaning of this word."

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

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

Listening to Kaysen's cold words, Draco's tears that he had managed to hold back burst out again, and the originally sweet sandwich became salty in less than five seconds.

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

Draco listened tremblingly, and raised his head a little aggrieved: "Can I take a leave and keep grinding here?"

"In this way, other little wizards will learn many more spells than you, and you don't want to be beaten without any ability to fight back in the next wizard duel or fight." Kaysen did not refuse, but just made the pros and cons clear.

"I'll be back after class."

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

After Draco left the office, Kaysen waved his hand and collected all the redstone powder scattered in the corner, which could be used directly as a fifth-grade textbook.

Soon, the first-grade morning class was almost over, and Draco returned to the alchemy office in a depressed mood, picked up the small file and started sharpening it.

And Kaysen still sat on the sofa and made a pot of green tea.

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

Kaysen 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 refreshing potions.

Of course, redstone is secondary, and he still sincerely hopes that this little wizard who speaks without thinking can learn the lesson this time.

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

In this way, the naive Professor Kaysen thought that everything was moving in a good direction.

Especially one day a week and a half later, Draco had only one red stone left.

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

Really.
