Dumbledore? He knows nothing about MC alchemy.

"Um... I remember that the first thing we talked about was Professor Kaysen picking a fight with Quirrell. How did we end up talking about the Dark Arts?" Ron suddenly joined the group chat and asked in confusion.

"........."

"........."

"......"

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

Because during lunch in the auditorium, when Professor Quirrell finished his meal and was about to leave, Kaisen stood up at the same time.

The two of them bumped into each other head-on. Kaisen was fine, but Quirrell was thrown to the ground.

At that moment, his defense finally broke down. Not long ago, this well-dressed Professor Kaisen in front of him was quite friendly to him in the professors' lounge.

Why? Since that Halloween, Kaisen seemed to have suddenly become a different person. Or rather, it cannot be said that he had become a different person. He was so friendly to other professors and young wizards, even Hagrid and Filch.

Only to myself...

Quirrell angrily pulled a handkerchief from his pocket, so quickly that even Voldemort behind his head didn't react.

"I want to duel with you!"

Kaisen tilted his head and reached out to take the handkerchief that was slowly flying towards him.

"Tell me 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.

"Are you not stuttering now? It's up to you. When you set up the ring, remember to send someone to find me." Kaisen put the handkerchief in his pocket and said casually.

"Hmph! Dumbledore, I, I'd like to ask you to come, to be the notary public for this, duel." Quirrell reacted, quickly stopped 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 waiting for you here...here!" Quirrell looked at Kaisen with red eyes and said viciously.

"uh-huh."

Kaisen shrugged, as if completely ignoring Quirrell's strange cry. He was wondering whether he should give Quirrell a little shock to his quality.

But in the end he didn't say anything. After all, there were so many young wizards here, and it would be bad if he taught them bad things.

But even if I don’t curse, I still have to take the necessary actions.

Kaisen moved with lightning speed, and his momentum rose from bottom to top like Mount Everest suddenly appearing between the worlds.

He raised a slender, straight middle finger.

Then Kaisen turned around and left the auditorium with satisfaction.

The little incident in the auditorium ended quickly, and Quirrell rushed back to his Defense Against the Dark Arts office, still furious.

"I may have thought there would be such a day, but I never thought it would come so soon, really." Neville muttered incoherently, with half a piece of bread in his mouth.

"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. Hermione speechlessly picked up the memory ball and the homework that Neville had left on the table.

The last one is Ron, who is holding two fried chicken legs. He said that he was afraid that Professor Kaisen was not full, so he brought some special food for Professor Kaisen.

If he hadn't already taken two bites of the chicken legs.

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

After the four little wizards arrived at Kaisen's office, they were embarrassed to find that... the office was already crowded, and even the outside was full of people. The entire corridor was filled with little wizards above the third grade.

The young wizards from the four major academies have never worked so hard in one direction as they do here.

Ron was also sharp-eyed enough to spot his two twin brothers at the door.

"Professor Kaisen! Professor! As long as you say it, we will ensure that Quirrell will not be able to leave the office!" One of the twins shouted loudly.

"Professor! You two are so bad! Look at me, I know black magic!"

"Professor Kaisen, I, I used my alchemical hand to make a big treasure, and I guarantee that it will give Quirrell an awesome alchemical shock!"

"Kaysen Church..."

"Professor Kaisen!!!"

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

Chapter 37 OHOHOH!!!

"...Are we still going in?" Hermione asked, looking at the huge crowd that could scare a socially anxious person to death.

"Go, why not!" Harry said as he rushed in, trying hard to squeeze in with his small body.

Neville was not to be outdone. He was even stronger than Harry, but unfortunately, he couldn't squeeze through the third-year wizards.

Professor Kaisen in the office had to stand on the desk to maintain order.

To be honest, if this incident hadn't happened, he wouldn't have known that he was so popular among students.

"Everyone! Everyone, listen to me, listen to me, I am very pleased that you have come!"

"But please believe me! I don't need a duel assistant or a duel agent, nor do I need you to help me assassinate Professor Quirrell in his office. Trust me and use my own strength, okay?"

The little wizards in the office and the corridor gradually returned to silence, and finally left his poor office after Kaisen begged him to do so.

After a while, Kaisen and four little wizards were the only ones left in the office.

"I hope you're not here to help me assassinate Quirrell."

"Of course we're not, Professor," Hermione explained quickly.

"Yeah, even if we have this idea, we don't have the strength." Harry said with an awkward smile.

"I sincerely hope you don't even have this idea," Kaisen said.

"Oh, we will. By the way, are you confident in the duel?"

"I guess so. In fact, this is what I want. Even if Quirrell doesn't challenge me to a duel today, I will still challenge him."

"After all, if we let him move around in the castle, there's no guarantee he'll cause any other danger. If we can use this duel to confine his activities to the hospital wing, it would be a small contribution to the safety of Hogwarts."

"So, professor, you are very confident?"

"That's it."

Quirrell set the duel time very quickly, so fast that from the moment he threw the gloves, of course, Quirrell didn't wear gloves, so he threw the handkerchief. From the moment he threw the handkerchief until the two of them stood on the duel stage, only six hours had passed.

At six o'clock in the afternoon, a dueling platform suddenly appeared in the center of the auditorium. Kaisen and Quirrell stood in the center, each holding their wand and pressing it against their chest.

In the middle of the two was Snape. After explaining the meaning and rules of the duel to the two and the young wizard watching, Snape asked the two to bow to each other.

Things have come to this point, and both of them bowed to each other. After all, this is the dueling arena at Hogwarts, not WWE.

No pre-game rituals that add to the anger.

After bowing, the two turned around at the same time and walked in their own directions. When Snape spoke, they turned around again at the same time.

Quirrell took the lead and swung his wand upwards: "The dragon has escaped!"

A giant python more than four meters long was suddenly summoned out and pounced towards Kaisen quickly.

Kaisen casually waved his wand, and pixels of fire evenly covered the giant python's body. He simply turned sideways, and the giant python brushed past his shadow and fell to the bottom of the platform.

After doing all this, he shrugged at Quirrell and spread his hands like a little bear, and people could understand the meaning in the blink of an eye.

"That's it?"

"It's not over yet."

Quirrell then quickly swiped his wand towards Kaisen's feet, and spikes of ground spread towards his feet.

Kaisen scratched his chin and tapped his wand. In an instant, the entire dueling stage turned into an obsidian surface.

The thorns that had already grown fell directly to the ground and turned into powder because their roots were broken and their magic power supply was depleted.

Just as Kaisen finished admiring his masterpiece and looked up, he saw Quirrell casting another silent spell towards him.

The spell was red, but given Quirrell's nature, he couldn't be sure whether the object flying over was meant to eliminate your weapon or knock you unconscious.

Of course, the greater possibility is that this will result in a complete destruction.

Kaisen was no longer arrogant and didn't need his wand anymore. He just stretched out his hand and waved it upwards. An obsidian wall blocked the spell, and the obsidian wall turned into fragments all over the ground.

As Quirrell's spells subsided, one wave followed another, and a giant dragon made of bright red flames pounced straight towards Kaisen.

Snape watched Quirrell cast the Fiery Blaze and quickly jumped off the platform, turning to look at Dumbledore.

Dumbledore waved his hand, signaling him to relax, and he seemed to be watching the Fire Curse with interest.

But Kaisen on the stage was not as calm as Dumbledore. Although he still remained calm on the surface, the damn fire in front of him did not look like a real fire at all.

He held a magic wand in one hand and a ball of water in the other. At this time, a grid of transparent cubes appeared in his mind on the duel stage.

It is also divided into three-dimensional axes.

It only takes a moment to fill all the space in this three-dimensional axis with water source blocks and stop them from flowing.

Such a momentary compression and filling of space should be able to directly plunder the living space of the Lihuo in front of us, or it can be explained more simply.

The water source block that suddenly appeared covered the fire, just like a computer file covering another file.

Just do it.

Kaisen looked at the huge fire dragon that was growing bigger and bigger, almost reaching the ceiling of the auditorium. He threw the water source cube on the corner of the ground with one hand, and held the magic wand with the other hand, tapping a corner of the Hogwarts ceiling. In an instant, a huge water source cube appeared in front of the two of them.

As for the fire dragon that had just covered the sky and the sun, it had already disappeared without a trace.

After destroying the fire dragon, Kaisen still hasn't forgotten why he picked a fight with Quirrell in the beginning and why he accepted Quirrell's duel until now.

To let this old guy stay in the medical wing for a few more days.

But he really only had to lie down for a few days. Before the duel, Dumbledore specifically told him not to harm Quirrell's life.

Just because of this one thing, the Wither Skull cannot be used.

However, the TNT flash was too light for Quirrell, and was far from enough to make him stay in the medical wing for a few more days.

Fortunately, from the time he arrived at Hogwarts until now, the students and professors have liked him very much, so.

"End Crystal!"
