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

"This place is really... simple and honest." After the two ran out of the mall, they saw a police car beeping and speeding over.

"Oh my god, back to the hotel."

After saying that, Kaisen teleported back, while Lupin hurriedly took out his wand and made a buzzing sound.

"Come on, drink some water, and then we will go directly to the magic market in Uruguay."

Lupin drank a bottle of water and said speechlessly: "Then why don't we go to that market at the beginning."

"Real wizards mine, and wizards only use crystal divination. I just thought it would be more convenient to find the source directly."

As Kaisen said, a map appeared in his hand, and he spread it flat on the table.

"We just need to use this map to find places with no buildings but a large number of people. That's probably where wizards gather."

Lupin came over and watched Kaisen's two fingers constantly shrinking the picture on the map until the whole of Uruguay was covered. He opened his mouth in surprise.

"How the hell did you do that?"

"Talent and hard work, I found it."

The two came to the hotel rooftop, and Kaisen directly took out a lump of lavender light. That was the magic of the invisibility potion. As for why he didn't drink it directly but took off his pants to fart to extract the magic...

Ahem...you still have to wear clothes, and extracting magic can directly make the clothes invisible.

Very humane.

Not long after, the two completely invisible people rode on a flying broom to a mountain far away from the city.

"Is this where wizards gather in Uruguay?" Lupin was a little confused. The productivity of the wizarding world...is just like that, so strictly speaking, it still depends on the Muggle world to survive.

This is the first time he has seen a wizard gathering place built in the wilderness.

"If this is not the base of some mysterious organization, then this is it." Kaisen walked in front with a map, and Lupin followed with a wand.

Soon the two saw huge tree houses, and a large open space in the center of the tree houses was densely packed with stalls.

"There are not many people in Uruguay, but there are many wizards." Lupin looked at this dense population and said with some surprise.

"Let's go in and take a look."

The two walked towards the innermost market. No one stopped them along the way. Well, the people are simple and honest, very good.

Kaisen and Lupin walked around the market again and again, and finally found a stall owner helplessly and asked helplessly.

"Why don't you have magic crystals in your market?"

"It's useless to have that thing. If anyone wants crystals, just go to the mines and pick them. They're not worth much anyway."

Kaysen and Lupin looked at each other: "Mine?"

"It's a Muggle mine. Just go in when no one is around or put on a Disillusionment Charm." The boss explained.

"Don't you want to buy it here?"

"Yes, I can, but I don't understand why anyone would buy it. It's useless." The boss said as he Apparated away and soon reappeared here with a huge stone ball.

"Cut this thing open, and there's crystal inside."

"Lupin, pay."

With the previous experience, Kaisen no longer had the idea of ​​taking out a small manuscript to give the crystal a try, and hurriedly greeted Lupin.

"Just give me a little as a token of appreciation."

In the end, Lupin and the boss had a long tug-of-war, and he took out a huge sum of three Galleons.

Kaysen quickly took the stone egg aside, took out a diamond pick and tapped it gently.

With a click, the stone egg cracked, revealing the beautiful transparent crystal inside. He quickly knocked off a piece of it with a diamond pick and placed it on the arcane workbench.

"Water Magic Crystal... Hmm? This purple one?"

The joy of obtaining the Water Magic Crystal had not yet subsided, and he saw a little bit of inappropriate purple in his eyes.

Knocked off a small piece with a diamond pick.

"Earth Magic Crystal..." Just as Kaisen was about to stand up and celebrate, he was quickly stopped by Lupin.

"What's wrong?"

"Did you find it? Do you still want to ask the boss where he found it?" Lupin did not answer immediately, but asked back.

"Hmm."

"Don't shout if you find it, put away the smile on your face, and it's better to show a frustrated expression before asking."

"Oh, I just realized it." Kaisen nodded, coughed twice to smooth out the smile on his face, and then found the boss again.

"Where did you find that stone egg?"

"It's called the Amethyst Mine. You can find any Muggle to find out."

"Would you mind drawing the location on the map for me?" Kaisen took out the map, turned off the small red dots representing humans on it, and handed it to the boss.

The boss took out a feather pen, gestured, and drew a small dot: "Probably here. The crystals in the shallow mines are occupied by Muggles. If you don't want to be discovered, or want some better quality, go to the deep mines."

"Thank you, generous sir." Kaisen quickly put away the map, put the crystal stone egg that Lupin was looking at into the ring, and rode directly on the Z9 broom. The two flew directly to the mine marked by the boss.

Soon, the two flew around the mine, each cast an invisibility spell on themselves, and walked into the mine.

On the way, they changed into camouflage uniforms under the passive eyes of a team of workers.

Gradually walking into the deep mine, the miner's lamps built by the workers were getting fewer and fewer, and Kaisen directly put on night vision for himself and Lupin.

Soon, they saw stone eggs one after another that looked like the boss's, not to say they were exactly the same, but they were exactly the same.

"Prioritize finding magical purple ones. I seem to have found a book on growing crystals in the library of Hogwarts before. We only need a basic crystal seed."

"I will..."

Lupin used the cutting spell, and Kaisen used a diamond pickaxe. Soon, one stone egg after another was cracked open. Most of them were water magic crystals. Of course, these were all put into the Ender Ring.

As for whether his office would be filled up again.

It would not.

I don't know if the ore layer here is too shallow, or what, most of the purple crystal stone eggs have no magic, and the ones with magic are all water-attributed crystals.

After thinking it over, Kaisen understood!

Since it is called the Magic Crystal of the Earth, it should be hidden deep in the earth, so...

Crack!

"Wow! Purple Legend!"
