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

It has been a while since the last alchemy party, and almost the entire Hogwarts envied the seventh-year alchemy that was in the spotlight.

However, behind this excitement, there are always people who can notice something else, such as Harry.

He noticed that since they went to Professor Kaysen's office that day and learned that the real dark wizard hidden in Hogwarts was the timid Professor Quirrell.

As long as Professor Kaysen and Professor Quirrell were in the same space, the strange smell of gunpowder always filled the nose.

I don't know why, it might be his illusion.

"I always feel that Professor Kaysen is looking for trouble with Quirrell, all the time, as long as they are together." In the library, Harry whispered to the four friends around him.

"Of course, a powerful wizard like Professor Kaysen who hates evil naturally has no good attitude towards dark wizards. This is normal."

Neville echoed.

"Everyone understands this. I just think that Professor Kesen, an alchemist, is targeting Quirrell, a dark wizard. What if Quirrell can't bear it anymore and assassinates Professor Kesen?" Hermione responded while writing a paper.

"Professor Kesen is very powerful. He can blow up the troll with just one move. Didn't you see it that day? The whole wall was blown up!" Neville immediately retorted when he heard that Kesen's combat power was underestimated.

"Of course, I'm not saying that Professor Kesen is not strong enough, but what if Professor Quirrell has a more sinister curse, dark magic or something like that?" Hermione retorted.

"Well, in fact, Professor Kesen can also do dark magic. He saved Hagrid who was entangled by a dark wizard in Knockturn Alley before. At that time, he used a kind of skull magic to kill the three dark wizards." Harry added.

"That's not black magic, how could Professor Kaysen use black magic?"

"But that's a skeleton."

"That's not black magic either."

Harry looked at the stubborn Neville and lost his temper. He didn't know how to refute.

"Uh... I remember that the first thing we talked about was Professor Kaysen picking a fight with Quirrell. How did it end up being about black magic?" Ron suddenly joined the group chat and asked in confusion.

"........."

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

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

Kaysen, one of the parties involved, was completely unaware of the whispered arguments in the library, but he was able to answer their questions quickly.

Because during lunch in the auditorium, when Professor Quirrell was about to leave after finishing his meal, Kaysen stood up at the same time.

The two bumped into each other, Kaysen was fine, but Quirrell was directly thrown over and fell on his buttocks.

At that moment, he finally broke his defense. Not long ago, the well-dressed Professor Kaysen in front of him was quite friendly to him in the professor's lounge.

Why, since that Halloween, this Kaisen seemed to have suddenly changed into a different person, or it could not be said that he had changed into a different person, he was so friendly to other professors and young wizards, even Hagrid and Filch.

Only to himself...

Quirrell took out a handkerchief from his pocket in anger, so fast that even Voldemort behind his head could not react.

"I want to duel with you!"

Kaysen tilted his head and reached out to take the handkerchief that flew slowly.

"Speak of a time."

"Tonight, in the Great Hall, I will defeat you in front of everyone!" Quirrell roared, and Voldemort behind his head rarely stopped him, as if he was also happy to see it happen, and wanted to use Quirrell to test the level of this emerging alchemy professor.

"Not stuttering at this time? It's up to you. When you set up the ring, remember to have someone come to find me." Kaisen put the handkerchief in his pocket and said casually.

"Hmph! Dumbledore, I, I want you to come, to be the notary of this duel, duel." Quirrell reacted, quickly recovered his stuttering, and looked eagerly at Dumbledore who was drinking a glass of lemonade.

"Oh... In that case, of course, no problem." Dumbledore agreed readily.

"In the evening hall, before dinner, I'll be here... waiting for you here!" Quirrell looked at Kaisen with red eyes and said viciously.

"Uh-huh."

Kaisen shrugged, as if he completely ignored Quirrell's weird cry. He was thinking whether he should give Quirrell a little quality shock.

But in the end he still didn't speak, after all, there are so many little wizards here, it would be bad if he taught them bad things.

But he didn't scold, and he still had to do what he should do.

I saw Kaisen with a lightning speed, and his momentum from bottom to top was like Mount Everest suddenly appearing between the worlds.

He raised a thin, straight middle finger.

Then Kaysen turned and left the auditorium with satisfaction.

The episode in the auditorium ended quickly, and Quirrell rushed back to his Defense Against the Dark Arts office with anger still not subsided.

"I may have thought that there would be such a day, but I didn't think it would come so soon, really." Neville still held half a piece of bread in his mouth, mumbling incoherently.

"No, I have to go to Professor Kaysen's office!" Harry only thought for two and a half seconds in his seat, then stood up quickly and ran towards the stairwell on the side of the auditorium.

"Hey, wait for us!" Neville quickly threw down half a piece of bread, and Hermione speechlessly picked up the memory ball and the homework that Neville had left on the table.

Finally, Ron was holding two fried chicken legs, and he brought them to Professor Kaysen in the name of fearing that Professor Kaysen was not full.

If he hadn't bitten the two chicken legs twice.

................................

After the four little wizards came to Kaysen's office, they found it embarrassing... The office was already crowded, and even the outside was full of people, and the entire corridor was full of little wizards above the third grade.

The little wizards of the four major colleges have never worked hard in one direction like here.

Ron also spotted his two twin brothers at the door with his sharp eyes.

"Professor Kaisen! Professor! As long as you open your mouth, we will make sure that Quirrell can't leave the office!" One of the twins shouted loudly.

"Professor! Twins suck! Look at me, I know black magic!"

"Professor Kaisen, I, I made a big treasure with my alchemical hands, and I guarantee that Quirrell will be shocked by the awesome alchemical power!"

"Professor Kaisen..."

"Professor Kaisen!!!"

"......Uh...can we still squeeze in here?" Ron wiped his greasy mouth and said with his eyes twitching uncontrollably.
