Hogwarts School of the Dark Arts

"Filch knows many secret passages in Hogwarts Castle." "But not all."

"And we know more than he does!" x2

"He doesn't know this room." "He doesn't know the secret passage in."

"Are you satisfied with this room? If not, we will take you somewhere else." x2

"No, this room is enough for me. Thank you very much!"

Xavier looked around the room in front of him. This room was not big, only about forty square meters, and the height was no more than four meters. It was small compared to other rooms in Hogwarts.

But it's enough for Xavier.

Especially the inside is very clean, there is no debris or dust, and there is no need to clean it at all.

The only drawback is that there are no windows, which means poor lighting and ventilation.

"That's good, we have to go beforehand."

"Tonight's game of cat and mouse has just begun."

"Oh, Fred, how many times have I told you, it's the mouse that catches the cat, we're the cats!"

"George, have you ever heard of a cat being caught by a mouse?"

……

The two brothers drifted farther and farther along the passage, and they split up inexplicably over the issue of identity.

"Aren't these two guys going to play with Filch?"

Thinking about it, it was really possible, especially since Filch had a cat and kept him with him every day.

"Although I didn't find the Room of Requirement, this room is enough. I really had no intention of planting a willow tree... I'll try to plant some whomping willow branches later!"

Xavier opened the box while thinking wildly, and kept taking things from inside to outside.

First there were some boxes containing medicine residue, then there were long wooden boards and regular rectangular wooden blocks, and finally there were boxes containing magic materials.

Wood blocks and boards are put together to form simple shelves, and things can be stored on them.

“It’s still unreliable to store medicine dregs in boxes because they can’t block the odor. I’ll have to change to glass bottles later.”

Xavier put the dregs of medicine aside while planning for the future.

Making do with simplicity and using local methods was just a last resort. The reason for choosing to use wooden boxes to store medicinal residues was because the dormitory could not store medicinal residues for a long time, and wooden boxes were easy to carry and transport.

Now with a fixed base, fragile glass containers are no longer an issue.

Place all the magic materials on the shelves.Xavier took a box of medicine residue and his eyes flickered.

"Even if Dumbledore discovers it, it shouldn't be a big deal. The decomposition technique is not an unforgivable curse like chewing a big melon. Just avoid the students to avoid unnecessary rumors."

"start!"

The Great Decomposition Technique!

A black light emerged from Xavier's hand, wrapping the box and the medicine residue inside, and decomposing them all in just the blink of an eye.

However, what he got made Xavier dumbfounded again.

"What is this liquid?!"

Just now, Xavier clearly saw a small crystal and a group of milky white liquid falling separately, but Xavier didn't react just now, causing them to fall to the ground and mix together.

Xavier used a box to move the small crystal. The milky white liquid staining it did not cause any damage to the wooden box.

Sniff~sniff~

"Why does this taste... a bit like narcissus root juice?"

After a slight hesitation, Xavier picked up the small crystal and carefully observed the liquid on it. The more he looked at it, the more it looked like narcissus root juice.

"If I remember correctly...Morgan grass..."

Xavier found the Morgan grass from the shelf, and then touched the liquid on the small crystal with the stem of the Morgan grass. The next moment, the liquid on the small crystal turned blue from where it touched the Morgan grass.

"It really is?!"

Xavier was overjoyed and quickly put a little bit of it into his mouth to feel it carefully.

"Well, very pure!"

"Turning waste into treasure!"

After wiping the narcissus root juice off the small crystal, he placed the small crystal in a box and Xavier took out his wand.

"Wingardim Leviosa!"

Xavier waved his wand to release the levitating spell, and a box of medicine residue immediately floated up and fixed in the air.

Xavier has long learned this kind of simple daily magic.

After fixing the position of the medicine dregs, Xavier placed one of the few glass bottles directly below it.

"The Great Decomposition Technique!"

Doing two things at once, Xavier maintains the levitating spell while releasing the Great Disintegration Technique!

It's not that Xavier's magic level is so high that it spans centuries, but because using the Great Disintegration Technique is as simple as breathing for Xavier.

However, Xavier soon discovered that he had miscalculated, and this time he actually decomposed liquids of three different colors!

Using the levitation spell to control three liquids and a small crystal to float in the air, Xavier scratched his hair.

Xavier can only use the levitating spell, but he is far from being able to control four objects to fly in different directions at the same time.

In fact, just controlling a pool of liquid to gather into a ball is beyond Xavier's ability.

"It's over~ This wave will be wasted again." Xavier sighed, ready to give up this wave of gains.

At this moment, suddenly, a soft voice sounded from behind.

"Do you need help?"

scare!

Xavier shook his hand, and the floating spell was instantly broken.

"Wingardim Leviosa~"

As a spell sounded, Xavier turned sideways and saw Dumbledore drawing circles with his wand.

Following Dumbledore's wand, four objects drew an arc in the air and flew towards Dumbledore's free left hand and finally stopped above the palm of his hand.

Dumbledore stretched out a finger to point at one of the white water balls, dipped his finger into it and looked at it before putting it in his mouth.

"Well, it's very pure white liquid... I have never tasted such pure white liquid... Can you send it to me for research?" Dumbledore asked.

"We have to pay more!" Xavier blurted out.

As soon as these words came out, Dumbledore and Xavier were both stunned. It seemed that neither of them expected Xavier to say these words.

"Okay." Dumbledore nodded after reacting: "How much?"

Once he heard that Dumbledore was really going to give him money, Xavier came back to his senses instantly.

"Why doesn't it cost one hundred and eighty galleons? You said it yourself, you have never seen such pure white essence. This is a precious material that transcends the ages and is the only one in the magic world!"

White Fresh Essence is a temporary name chosen by Xavier. It has a name that is bluffing, so the product can be sold at a high price!

As the saying goes: Scientific and technological innovation is based on name change!

"This is not the only one." Dumbledore shook his head: "I saw it just now...did you invent that magic yourself?"

"That's right. One day I suddenly mastered it. Can it be regarded as my own invention?"

Dumbledore nodded, then reached out and touched a ball of light blue liquid, dipped a little into his mouth.

"It tastes really good. Maybe we can develop a new drink based on it, which should be very popular."

Xavier's eyes suddenly lit up.
