Dumbledore? He knows nothing about MC alchemy.

Dumbledore's frightened eyes were filled with undisguised anger, but he managed to calm his expression and walked over quickly: "...It's just exhausted self-preservation, Severus."

Snape quickly took out two bottles of magic potion from his arms, pushed Harry and Neville aside as if they were trash, then opened the potion stopper and poured it into Kaisen's mouth. He also did not forget to help Kaisen lift his chin to prevent him from choking.

"That damn dark wizard, how dare he...how dare he!" Professor McGonagall looked at the devastated battlefield and Kaisen lying unconscious on the ground with red eyes.

She couldn't imagine what it would be like if Kaisen wasn't here, if it was Hagrid who led these little wizards out to patrol the Forbidden Forest today...

She felt suffocated. She just wanted to give the five little wizards who had made mistakes a shocking punishment, but...

Professor Flitwick and Professor Sprout were searching with their wands in hand. If the fire had not been completely extinguished, it would be a big trouble.

"Principal Dumbledore, Professor Kaysen..." The other three little wizards also ran over and asked Dumbledore.

"Severus is an expert in this area."

"...His magic power is overdrawn, but it can be replenished by drinking two bottles of potion. However, his mental power is exhausted... He won't be able to attend classes for a week." Snape said with a frown.

Dumbledore nodded: "This is the best outcome. Send him back to the office."

"Don't send him to the infirmary...Oh." Harry said halfway quickly, and suddenly realized that there was a dark wizard named Quirrell in the infirmary who was at odds with Professor Kaysen.

If Professor Kaisen sent it over now, it would be like sending food to Quirrell, so it would be better to go to his own office. Therefore, he quickly stopped talking.

Dumbledore looked over and nodded in agreement.

"Severus, please brew the potion." Dumbledore said as he gathered everyone together. After a burst of fire, everyone appeared in the alchemy office.

After Dumbledore sent everyone away, only he, Snape, and Kaisen who was unconscious on the bed were left in the office.

And now Dumbledore is leaving too.

"Where are you going?" Snape asked.

"I need to go find the alchemy textbooks from my school days. Looks like I'll need to be a substitute alchemy professor for a week."

"I don't think it's necessary!"

Someone who had just been unconscious on the bed struggled to sit up.

Chapter 53 Do you think one person is enough?

“Actually, I can come by myself…”

"What to eat?"

"Hmm... give me an orange."

Hermione sat under a small stool, nimbly peeled open an orange, broke off a slice and handed it to the mouth of Kaisen who was lying on the bed. The latter opened his mouth and ate it with a look of humiliation.

The office and bedroom were connected, and the door was not closed at this time, so Kaisen could just see what the other little wizards were doing.

For example... Harry, he held a wand in his left hand and a rag in his right hand, cleaning the office's hygiene conditions without any problems, both as a magician and a Muggle.

Neville washed the fruits that were continuously delivered to the door. There was no problem in washing fruits like apples and pears, but this kid even washed fruits that needed to be peeled, such as oranges and bananas.

According to him, he was afraid of contaminating the washed fruit by handling the unwashed fruit.

Well... he is indeed a very good kid... very good.

Ron was busy bringing basket after basket of fruit baskets from outside the office door into the office, and wrote down their names and the cards on the fruit baskets, and stacked them together on the desk.

In the corner, there was a little wizard with Perkin-hair who was using hot water to heat the potion in the potion bottle, and using a mercury thermometer to constantly try to keep the temperature within the range of 37.5 degrees Celsius.

"Honestly, I'm not even hurt. You guys really shouldn't be like this." Kaisen said dryly while being trapped on the bed by a magic called [Tough Stare].

"Professor Snape said..."

"I suspect Severus is taking revenge for the Christmas present I gave him... but I can see he did use it. Did you notice his hair?"

Hermione nodded in understanding. "I was saying that Professor Snape's hair has returned to normal since returning from Christmas break."

"Well, that's my masterpiece. Do you want to learn it? I can teach you as long as you let me stand up and go to the alchemy workbench in the office outside. It's one-on-one. Other little wizards don't have this treatment." Kaisen seduced like a big bad wolf lying on his grandmother's bed.

"...Well...although this condition is very tempting, I refuse." Hermione said with difficulty.

"Oh...don't you have classes? Don't tell me you took time off to come and take care of me. I told you in advance that I will never appreciate your behavior of not attending classes."

"The next class is in half an hour."

"Then go quickly. Believe me, I can handle myself here. I will definitely not be thrown over my shoulder by a slipper when I get out of bed, and then hit my head on the floor and go straight to death." Kaisen said with a smile on his face.

"Our roommates will help us bring our books, don't worry about that, Professor."

"Then you should go to the classroom anyway, right?"

"Yes, but that will be in twenty minutes."

"OK..."

Although these twenty minutes were extremely long, they still gave Kaisen a little comfort.

It only takes twenty minutes, just twenty minutes.

Kaisen stared at the ceiling with lifeless eyes. When he counted to fifteen minutes and twenty-six seconds, Draco moved quickly and brought over a bottle of thirty-eight-nine-degree potion.

He calculated this temperature based on the heat conduction of the glass bottle, the specific heat capacity of the liquid, and his movement speed. When he walked over, the temperature was about 37.5 degrees.

"Put it here, you can go out now."

Draco's expression instantly fell, but this time he surprisingly didn't say any unnecessary trash talk. He just put the potion on the bedside table and left.

"I really have to thank Severus for making the family tree centered around him. Even though he put me in this miserable situation, the potion he brewed was still...why does it smell like garlic? Did he chop up Quirrell and add it in?"

After much begging, Kaisen finally got Hermione to agree to let him sit up a little, and then he stretched out an arm from under the quilt to drink the potion himself.

However, the first second after he took the potion, he was so shocked by the strange smell that he wore a mask of pain.

"The potion in the morning still tastes like orange soda..."

Kaisen lay on the bed with a hopeless look on his face. He felt that his sweat had left a human figure on the sheets, but the quilt still held him tightly.

At this moment, I took a sip of the potion which was even warmer than normal temperature, and immediately felt that this life didn't need to be that long.

Really.

Fortunately, the time is almost up, and he still doesn't believe that Hermione and the other first-year kids can come up with any magic to make him stay in bed obediently.

Even Dumbledore couldn't get himself to stay in bed, so how could they get themselves to stay in bed?

It must be impossible!

Soon, in Kaisen's time perception, twenty minutes were finally calculated, but Hermione and the others did not leave. Instead, they opened the door of the office, and a group of people lined up in an orderly manner and walked in.

"What's happening here?"

Hermione put her hands behind her back and said with a stern face: "In order to let you, Professor, stay in bed and recover from your injuries, we specially found some external help."

"...Clam?"

Soon the first young wizard came in, Angelina, a third-year Gryffindor...

This child is a good child, but... no, considering that the gift she sent for Christmas was a pair of thick gloves and she reminded herself to wear thick clothes when it gets cold, if she stays, she will probably have to add two or three more layers of quilts.

For his own safety, Kaisen shook his head frantically with a terrified face, and Angelina retreated with a little disappointment when she saw this.

The next one is the little wizard from Hufflepuff. Although he is in the third year, he is Cedric, the fourth-year alchemy class representative appointed by himself.

This guy is a good guy. The most important thing is that he is honest and flexible, and he is strong and healthy. He understands very well that he is in a situation like a furnace at this time.

Well, actually, neither of them is true. It’s just that Cedric is easy to talk to. Maybe if I talk to him nicely, he will secretly tell me something.

Kaisen smiled with relief: "Cedric, please stay. You're enough. Let them all go. If you have time, go out for a walk or sleep in bed. It's much better than staying here."

Cedric nodded and stood in the corner of the bedroom.

Hermione then called the next person in.

"Huh??? What's going on?" Kaisen asked in confusion.

"Professor, with your personality, do you think one person is enough?"

Chapter 54 The Patil Sisters and the Weasley Twins

"That's enough... Really enough..."

Kaisen watched with tears in his eyes as the little wizards walked in from outside the office.

He looked at the little wizards one by one, recalling their personalities and habits...

Calling them in can't be said to be inviting a wolf into the house, but it should be said to be pushing yourself into a fire pit.

For example, Tracy, a third-grader, who could send pink bubbles to herself and output admiration points in the first class, is naturally not an option.

And there was Casli. He clearly remembered that this seventh-grade little witch had classes this afternoon, so he quickly sent her away and told her to go back and attend class properly.

Kaisen watched as the little wizards came in and went out one by one, until he saw a pair of twins walk in.

The Patil sisters, one is from Gryffindor and the other is from Ravenclaw, but they are both in the first year.

Hermione was also a little confused. She heard at noon that Parvati asked for leave for the afternoon class and thought it was something else. It turned out to be this...

Kaisen looked at the two sisters inquiringly. He clearly remembered that the two sisters always held hands when they appeared together. Although it was more offensive on the stairs, whenever the two appeared in the same space and were standing, they always held hands.

It's not his fault that he knew so much about it. It was because before he learned the Ender Teleport technique, the two sisters were late for several classes, so it would be strange if he didn't know.

However, this time, one of the Patil sisters had her hands behind her back, and the other subconsciously hugged her shoulders. However, she may have felt that this was a bit unladylike, so she slowly put her hands down from her shoulders. However, it was still difficult to conceal her extremely distinctive temperament.

"It's them! Cedric and the Patil sisters, it's them!" Kaisen made the decision.

"Okay, but three should be enough." Although Hermione still wanted to add two more people, she nodded after thinking about it, walked out of the office and sent the remaining people who were still queuing away. She also ran towards the classroom in a panic with Harry and the others, holding her books.

There were only four people left in the office. Kaisen stretched out his body and relaxed. Suddenly, two bottles of milk appeared in his hands. He couldn't remember when he unlocked them.

Now basically, after he goes to sleep every day, he will unlock one or two blocks the next day, and this milk source block is just one of them.

He threw two bottles of milk to the Patil sisters, who quickly caught them, looked at each other, and drank them all in one gulp.

Then Cedric's expression became a little broken: "You guys worked hard to get here..."

Kaisen nodded as well, looking at the Weasley twins who had returned to their original appearance. "How did you convince Patil and the others to give you their hair? I remember they valued their hair very much. No one would cut off their hair and give it to you."

The Weasley twins looked at each other while changing clothes...

"That's not important. What's important is that your milk is magical."
