Hogwarts Kryptonian.

Chapter 22 The Halloween Gift
The dinner party on Hallow's Eve broke up in a noisy and unhappy way because of the intrusion of the mountain monster. The rumors of the mountain monster were also spread by word of mouth in the lounges of various colleges, and it became extremely terrifying.

The fact that Lu Yunkai and Harry killed the mountain monster was also strictly controlled by the teachers, and they did not disclose it to other students.On the contrary, the prefects who have been paying attention to the points of the Academy Cup found that the points of Gryffindor and Slytherin had decreased a little.

The homecoming weekend that the students of Hogwarts (mainly Slytherin actually) have been looking forward to for two months has arrived.

Although the school is good, but for Slytherins whose families are generally well off and most of their parents don't work, so they don't have to worry about not having time to take care of their children, no matter how good the dormitory is, it's not as comfortable as home.Especially the first-year freshmen who entered this year all want to go home and report their school life to their families.

So when Lu Yunkai, who took a long nap at noon the next day, wandered to the auditorium for lunch, he found that he was the only Slytherin first-year student who stayed in school.

Even Chris could squat on the dining table and talk to Lu Yunkai without any scruples.

"Meow, you slept too hard last night, didn't you? I called you several times but didn't wake you up."

"Is there? But I didn't sleep very well, basically I was dreaming all the time." Lu Yunkai yawned with a listless look, "What do you want me to do?"

"Meow! Not long after you left last night, I saw Snape stop Quirrell in the corridor and threaten him for a long time." Chris said excitedly.

"Can you stop being curious about such things!" Lu Yunkai glared at Chris, "Aren't you afraid of causing trouble?"

"Meow? Are you ashamed to say me? Yesterday you ran to fight with the mountain monster. Isn't it more dangerous than me secretly listening to people talking?" Chris looked up with disdain on her face.

"It's just you talking nonsense." Lu Yunkai felt that there was no way to refute this, so he decided to bury his head and continue eating.

"I've decided, I'll follow them for a while to find out what's the secret...Meow? Is there an owl looking for you?"

At this moment, an owl flew into the auditorium and threw a package in front of Lu Yunkai.

"Someone actually sent me something?" Lu Yunkai was taken aback.

"Maybe it was a Halloween present from your friend?"

"How can I send things to my friends! And is there any need to give gifts on Halloween?" Lu Yun gave Chris a blank look, and opened the package with [-]% curiosity.

Inside was a very old notebook. Lu Yunkai took it out and flipped through it casually, but there was not a single word in it.

Is this some kind of prank?Gift yourself an old, unused notebook?

[Six Nat, is it for sale? 】

The system also gave an estimate that was so low that Lu Yunkai was speechless.

At this price, you can only buy a piece of parchment, right?This is a notebook after all!
Forget it, keep it for yourself!Lu Yunkai shook his head helplessly.

"Meow? What is this?" Chris had an absurd expression on her face.

"Who knows! Maybe someone who likes to make fun of people is teasing me?" Lu Yunkai didn't take it seriously, put his notebook aside, and continued to eat lunch.

"Could it be that old bastard from Knockturn Alley sent you?" Chris reached out her paw suspiciously and touched the notebook.

Chris's silly gesture made Lu Yun laugh.It is really rare to see it like a cat at ordinary times.

Although it doesn't seem to be a cat originally...

After a leisurely lunch, Lu Yunkai met Harry and Ron in the front garden of the school.

It was expected by Lu Yunkai that Harry didn't come home. After all, he was a homeless person just like himself, but Ron and his three older brothers didn't come home either. Lu Yunkai was somewhat surprised.

As far as he knew, Ron's mother didn't need to go to work either.They are not allowed to go home at this time, maybe it is really just because there are too many children...

But no matter what, after the previous day's "Life and Death Together", the friendship between Lu Yunkai and the two of them, which had already faded, was strengthened again.

Harry also didn't forget to thank Hermione who helped her back home, and Ron brought back Hermione's complaint of "He didn't even cast the Levitation Curse, I can't believe it" ...

But after Hermione stood in front of the three of them the night before and took all the blame on herself, none of the three of them would mind what this kind-hearted but foul-mouthed girl said.

The three got together and chatted for a while, Harry and Ron went to play Quidditch on a broomstick together, Lu Yunkai, who had no talent for flying, declined their invitation and went to the library.

He wanted to check the formula of the blasting corrosion potion he used yesterday, and then try to make one himself.

In this way, after sitting in the library for an entire afternoon, he finally found the formula in the fifth book he read, the "Encyclopedia of Potions" recommended by the librarian Mrs. Pince.

After copying the recipe, production method, and precautions on the "Halloween gift" received at noon, Lu Yunkai returned to the Slytherin lounge.

"Well, the venom of the poison horned beast, the venom of the cobra, the venom of the acromantula, and the scales of the fire dragon..." Lu Yunkai opened the notebook, and began to buy materials from the system one by one according to the records on it.

There was no one in the lounge, so naturally Lu Yunkai didn't need to avoid suspicion, he conjured potion bottles out of thin air and put them on the table.

The materials are not expensive. There are seven kinds of raw materials in total, and four gold Galleons opened by Lu Yun were used, and more than half of them were spent on the venom of the acromantia.

And when Lu Yun started to make it, he finally understood that the reason why this potion can be sold at an almost sky-high price of more than 100 Galleons in the system was not because of the material at all, but because of the manufacturing process.

It's too cumbersome! !
The three kinds of venom need to be heated in three different crucibles, because their respective heating speeds are different, and the dragon scales also need to be accurately divided into two parts. The part is to be ground into powder at low temperature...

Lu Yunkai spent the whole afternoon without completing the pretreatment of raw materials.

But this also aroused Lu Yunkai's desire to win.

Anyway, there is nothing else to do during the Halloween holiday, so let's make medicine!
After dinner, continue.Lu Yunkai sat in his "exclusive seat" in the lounge until late at night.

"...Pour the hot fire dragon scale powder into the crucible, boil for 1 minute, then leave the fire to stand for half a minute, then add the dew of the screaming rose, and it's done. Huh! Hurry up! Hurry up!"

Lu Yunkai poured a pinch of powder into the crucible, stirred it with a stirring rod, and then activated the 1-minute timer.

It's almost finished!
While feeling emotional, Lu Yunkai waved the magic wand in his hand.

"Clean up."

Cleansing spell, this spell can be said to be the most proficient spell Lu Yunkai uses now.

After tidying up the crucible, medicine mortar and other things, one minute is up, let it stand away from the fire, and add dew.

however.

"Why is the color wrong?"

Lu Yunkai looked at the blue potion in the crucible, a little dazed.

He has made a lot of potions in the past two months. Although the quality is good or bad, and some have even failed, there has never been such a situation where the finished product is completely different from the expected color!
What went wrong?
Lu Yunkai's attention could only be shifted back to the notes, reviewing them one by one, recalling whether he made a mistake in any step.

Looked line by line, but did not find any problems.
-
Maybe you could try adding a few drops of dragon's blood to it?
Suddenly, a line of words appeared on the bottom line of the notebook.

Lu Yunkai was taken aback.

Could it be that he has been hallucinating from working continuously for too long?He rubbed his eyes.

The line is still there.

"...Who is it?" Lu Yun opened his eyelids and asked frantically.

But in the empty lounge, there was no response.

It was quiet for a while.

"Is this some kind of hellish Halloween trick?" Lu Yunkai directly closed the notebook, and then poured the potion from the crucible into the red crystal bottle.

[Unknown drug mixture, five sickles, is it for sale? 】

The phantom in front of him made Lu Yunkai's open mouth unable to close.

right? ?The potion that I failed to make before, as long as I pour it into this red crystal bottle, it will become a first-class potion!
Unless the recipe I made this time is wrong.

Is it...

Lu Yunkai remembered that line of words that did not know how to appear.

Forget it, anyway, you can only sell five Sickles, and if you break it, you can treat these few Galleons as raw materials for nothing! !

Lu Yunkai spent a few more Sickles to exchange three drops of fire dragon's blood from the system, and dropped them into the red crystal bottle.

The red to purple fire dragon blood dripped into the dark blue potion, and the color of the potion quickly turned into a color between dark purple and black.

The color seems right?

Lu Yunkai activated the system again.

[Level 120 Explosive Corrosion Potion, [-] Galleons.Is it for sale? 】

It's okay?Is it really just a few drops of fire dragon blood? ?
Lu Yunkai was stunned.

He was sure that when he copied it from the book, he didn't miss a single word!Why is there a raw material missing? ?
More importantly...

Lu Yunkai looked at the notebook that he had closed.

Why can this notebook make up this raw material?Is this thing really just a Halloween joke? ?
