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

After leaving Bojinbok Magic Shop, Kaisen stood in the middle of the road with his hands on his hips.

He was wondering where to find the next store, until a commotion not far away caught his attention.

A middle-aged wizard used a wand and expulsion spells to continuously expel a young wizard who looked down and out.

The young wizard also held a crystal block filled with white mist in his arms, about the size of a basketball.

The boss who had expelled him returned to his shop, and the down-and-out wizard took out his wand and looked like he was about to apparate away.

Seeing this, Kaisen quickly shouted: "Wait a minute, sir!"

The down-and-out wizard looked over with some confusion.

"Sir, would you mind if I knock off a small piece of your crystal for experimentation?" Kaison asked.

The down-and-out wizard thought for a moment and put down the crystal: "As you wish, sir."

Kaisen nodded, took out a small manuscript, knocked out a piece, and put the pieces into the Mathematical Olympiad workbench. Soon a transformation of joy appeared on his face.

"I got the magic crystal of order! Please make a price."

The downtrodden wizard stretched out five fingers tentatively.

"Five hundred galleons? Let me take a look... Do you support the discount? Or we can call each other's names and addresses. I am the alchemy professor at Hogwarts. You don't have to worry about finding me. Don’t worry about me defaulting!”

Kaisen opened the ender box ring and looked at it. Unfortunately, a large part of his salary for one semester was spent on drinking.

Shameless Dumbledore!

"Um, I said...five..."

"Five thousand gold Galleons... That's fine. Don't move around here. I'll go to Gringotts to get a big deal..." As he said that, Kaison was about to teleport to Gringotts, muttering: " This is definitely the last time."

"Actually... um... five hundred is just five hundred!" the down-and-out wizard said.

"..Then five hundred. Look at these." Kaysen pulled out all the Galleons in the ring: "These are three hundred and twenty Galleons. I will go to Hogwarts to get the rest. "How about we come together?" Kaisen held the crystal in his arms and said with no intention of letting go.

"Uh, okay."

"Let's go then. Do you know how to apparate? Let's apparate outside Hogwarts and then walk into the castle?"

"Okay." The fallen wizard nodded, took out his wand and waved it, and he twisted up and disappeared in the blink of an eye.

Kaison breathed a sigh of relief and teleported to the office. He first placed the crystal in the office and then teleported outside the castle again, where he saw the lonely wizard who was waiting.

"Let's go in and find Dumbledore. He conservatively owes me two-thirds of my salary. Although it may not actually be that much, there is absolutely nothing wrong with letting him pay for it if I have the money."

The two of them arrived at the principal's office all the way. The fallen wizard looked at the stone gatekeeper statue in front of him and was somewhat silent: "I'll just wait here. You can go get the money, I won't go up."

"Um...Okay, wait a minute." Kaysen casually said a password that he didn't know the specific meaning of. This is a habit of Dumbledore, and the regular people headed by Honey Candy, Cockroach Pile and Lemon Snow Baby Resident order.

Most of them are passwords used privately by professors.

The password with no specific meaning like what he is saying now is specifically used to open the principal's office in front of outsiders, the little wizard.

Therefore, in the entire British wizarding community, except for the faculty and staff of Hogwarts, there are only a few people who know that Dumbledore's password is a hodgepodge of candy.

After entering the principal's office, before Kayson could say anything, Dumbledore happily took out a hundred gold galleons and placed it in front of Kayson.

"The man downstairs is... Remus Lupin, and he is a werewolf."

"Oh..." Kaisen put away the gold galleons and nodded in realization: "I asked you why the merchants in Knockturn Alley don't seem to like him very much."

"Well...can I give you a simple task?" Dumbledore then asked.

"you say."

"What are your plans for this vacation?"

"Running around the world, I want to collect those magic crystals."

"...In that case, how about you help me improve his living conditions during this holiday? For example, you can use the remaining one hundred galleons to hire him as a bodyguard in two months' salary. On a full moon night, he can I'll find a secluded place to bear it alone, so you don't have to worry," Dumbledore said quietly.

"Oh... you are friends?"

"He was once my student."

"Needless to say, who in the entire English wizarding world is not your student?"

"He was one of the closer students and he joined the club I formed."

"Oh... sure, it doesn't have to be some black wizard." Kaison nodded.

"Thank you very much."

"uh-huh...................."

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

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

"Why are you still waiting here?" Dumbledore asked with some confusion.

"One hundred gold galleons is not enough," Kaison said.

"...What did you buy from Remus?"

"Magic crystal."

"How big?"

"It's as big as a basketball..."

Dumbledore sat up helplessly from the chair, with his hands behind his back, looking at the Forbidden Forest in the distance.

"A crystal the size of a basketball......... How did he quote you the price at that time."

Kaysen recalled: "He held out five fingers."

"That's right, five gold Galleons, right?" Dumbledore turned and looked at Kaisen strangely.

The latter suddenly touched his nose awkwardly.

"How much did you spend?"

"Fifteen Galleons?"

"Fifty Galleons...right?"

Kaysen remained silent, just touching his chin with his hand in silence.

"Tell me, Kaisen, forgive me, an old man, I really can't guess."

"Emm... Five hundred gold Galleons."

Dumbledore looked at Kaisen with a look that was somehow three parts strange, three parts helpless, and four parts pity.

In the end, he took out a bag with six hundred gold Galleons in it.

"Forget about the remaining 200 gold galleons. I sincerely hope you can find a bodyguard to go with you. Just consider it as helping an old man like me take care of my former students. How about it?"

Kaysen packed all the galleons: "Of course... why don't you give it to him directly?"

"He has a very fragile self-esteem."
