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

"Hey Hagrid! I knew you were here!" Kaisen looked at Hagrid who was fertilizing the pumpkin and greeted him.

"Kasen! How is your job as a professor? Are the little wizards very naughty!" Hagrid straightened up and responded.

"Not really. To be honest, the little wizards who report to me about alchemy are all very well behaved. By the way, are you free today?"

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

"So... to be honest, it's better to drink in your hut. It's a bit too dirty here." In the Hog's Head Tavern, Kaisen kept wiping the table in front of him with a handkerchief with some disdain. As for the wine glass, he prepared it himself.

"Don't worry about these details. Drinking here is the atmosphere, and we can drink freely without worrying about encountering danger like in other places. The boss here is a powerful and scary wizard. No one dares to make trouble in his place." Hagrid said comfortingly.

"Okay, I won't remember these things if I drink too much." Kaisen picked up the whiskey on the table and poured it into his glass. He clinked glasses with Hagrid and poured it into his mouth.

"Eh? I don't feel as dizzy as last time. It seems that I have made considerable progress in terms of my alcohol tolerance."

"Of course. Before, I didn't enjoy drinking with others. They lay on the ground. Only you can drink on par with me... But I remember you said last time that drinking is like a dog?" Hagrid scratched his head and said.

"Oh... Did I say that?"

Hagrid rolled his eyes: "No, you didn't say that, I remembered it wrong!"

"That's right!" Kaisen picked up the glass and clinked it with Hagrid again, but this time he felt a little dizzy.

Slowly, he couldn't count how many bottles of whiskey were in front of his table. Of course, there were not only whiskeys, but also various distilled liquors used as base liquors outside, vodka, gin, brandy, tequila and the like filled the table in front of the two of them.

Of course, there was also the surrounding floor.

And a figure in a black robe with an unclear face considered where to land and finally sat down.

"You two? Mind if you want to drink together?" the black-robed man said in a low voice.

"I really do." Kaisen shook his head.

"Then, mind if you want to make a bet? I have the money to bet. Look at this big thing! I won this big dragon egg from someone else!"

The moment he heard about the dragon egg, Hagrid, who was originally drowsy, suddenly became more than half awake, but only more than half.

"What do you want to bet?"

"Actually, I know you, Hagrid, the gamekeeper at Hogwarts. I heard that you are very knowledgeable about magical animals. I happen to have a three-headed dog, but it seems a little too excited. I want to know what I should do to calm it down. If your method works, this dragon egg will be yours." The black-robed man said.

"This is simple. The three-headed dog likes music very much. You just need to play some soothing music for him and he will calm down until he falls asleep. I recommend the harp. The three-headed dog especially likes that kind of music."

Kaisen leaned on the bottle of wine and looked at the black-robed man beside him. For some reason, he always felt that there was something wrong with him.

But because of the alcohol, he couldn't react. What was the problem?

Forget it, who cares!

He poured himself another glass of wine and drank it down. Soon, the black-robed man handed the dragon egg to Hagrid and looked at himself who was dazed.

"Professor Kaisen, to be honest, you have been in the limelight recently. I heard that you used a red stone that you made yourself to make a lot of alchemical creations?"

Kaysen burped and recalled. Well, he did use redstone to make a high-end alchemical induction cooker for Snape.

"Yeah, what's wrong?"

"Don't get me wrong, this is just a small request. I made a small object myself according to the redstone theory you taught in the sixth grade, but I accidentally arranged the route wrong when I was arranging the line. I don't know which one is the real switch. What should I do?" The black-robed man asked softly.

"Where did you get the redstone?"

"A sixth-grade student gave it to me, saying it was a product of their professor's alchemy, and asked me to cherish it."

"Is that so? Just cut off the main redstone route, and then let the redstone main route connect the redstone blocks."

"So simple?"

"Haven't you learned runes? The two are similar?"

Kaysen's confused mind has almost reacted to who this black-robed man is.

If he only asked Hagrid about the three-headed dog, then he might really have a three-headed dog by chance.

But he also asked himself about the redstone by the way. The three-headed dog plus the redstone, anyway, he doesn't think there are such coincidences in the world. From this, it can be concluded that this black-robed man is almost certainly Quirrell.

But this is just right. Before, Dumbledore asked him to use a clever method to tell Quirrell how to pass through the piston door, and he was thinking about how to tell him.

As a result, when I feel sleepy, I send a pillow. Isn't this just right?

"Thank you, both of you. By the way, Hagrid, this dragon egg is for you." The man in black robe, or rather Quirrell, left the dragon egg on the table and left the Hog's Head Tavern.

"Haha, Kaisen! I didn't expect that we would have such a big surprise when we came to drink, a dragon egg! Haha!" Hagrid was originally laughing and holding the dragon egg in his arms, but he stopped laughing instantly when he saw Kaisen pouring wine into his mouth.

"Am I a little too much of a fish?"

"What do you think?"

"Sorry, sorry, let's have a toast!"

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

The next day...

"It's 29 gold Galleons plus 6 silver Sickles in total. I'll round it off to 30 gold Galleons." The old man with a goatee said in a flat tone.

Kaisen was about to take out the money when his action froze, obviously shocked by the reverse rounding operation.

However, he didn't have much opinion on this. He and Hagrid slept in the tavern all night yesterday and occupied the table until this morning, which did delay other people's business.

Moreover, the two of them who slept all night did not lose anything, from dragon eggs to Galleons, after a night, they were still in a crowded tavern.

With security done to this extent, it's not a problem to give one more Galleon.

"Thirty Galleons, count them?" Kaisen took out thirty Galleons and lined them up on the bar.

"No need." The old man put all the Galleons away and stood back, continuing to wipe his dirty wine glass with his dirty rag.
