Hogwarts Kryptonian.

Chapter 40

"Yun Kai, what's wrong with you?"

"nothing much!"

"It's nothing! You've been smirking here for a long time."

"sorry!"

Lu Yunkai scratched his head in embarrassment, and handed Daphne a scroll of parchment beside the crucible.

"...What are you doing?" Daphne was taken aback.

"You came to me for a metamorphosis paper?"

"I'll just take a look, I won't copy it." Daphne's face flushed slightly, and she took the parchment roll.

"Every time you say that, last time Professor McGonagall almost took our paper and read it together." Lu Yun gave Daphne a blank look, "You should change it a little bit."

"I know!!" Daphne became more and more embarrassed by the words, so she could only change the subject: "What kind of medicine are you brewing?"

"this."

Lu Yunkai pointed to the prescription given to him in the notebook that he restored from memory on the table.He wasn't worried that Daphne would see anything wrong with this prescription.

however.

Daphne glanced over.

"Isn't this the formula in the book I gave you!!"

"Is there this recipe in the book you gave me?" Lu Yunkai was taken aback.

"Yeah! I remember it very clearly." Daphne nodded, pointing at the parchment, "Especially this one, forgetfulness."

"Well, this amnesiac is very pretty..."

"Yunkai! You don't deserve this thing." Daphne turned over Lu Yunkai's parchment, then looked at Lu Yunkai and said seriously.

"Huh? Why?"

"When I was copying the book, I thought the name of forgetfulness grass seemed to be useful for improving memory. I asked my father what it was. He told me that this kind of grassland is very common, but because it was found to be highly poisonous, magic The Ministry has cleaned it up, and it is rare now. This prescription is probably a very powerful poison."

"Poison... Poison??" Lu Yunkai was dumbfounded.

He looked at the phantom in front of him.

[Forgetfulness Grass: Ornamental plants.Four Galleons per plant. 】

The system didn't say it was poisonous! !
"I'm not lying to you!" Daphne nodded seriously.

"But..." Lu Yunkai glanced at Xu Ying again.

He didn't know whom to trust.

"Why don't you ask Professor Sprout?" Seeing whether Lu Yunkai didn't believe it, Daphne could only continue, "You don't want to mix this medicine yet!"

"...It's okay, boil the potion first, and I haven't bought the forgetfulness grass yet." Lu Yunkai lied, and secretly put away a portion of the forgetfulness grass that he had chopped up next to him.

"Of course you can't buy it. You can't buy forgetfulness grass in the whole of England, including Knockturn Alley...unless you find your friends." Daphne thought of Phoenix's tears.

"...I'll ask Professor Sprout."

Lu Yunkai immediately stood up.

Can't buy it in the whole of England?No wonder this thing sells for four gold Galleons per stalk of grass!In potion materials, this is already at the ceiling level.

It is almost catching up with the selling price of Phoenix Tears.

"Then I'll go too!" Daphne also stood up.

"You? Let's stay and read the paper! It's due tomorrow. Aren't you afraid that Professor McGonagall will leave you a bunch of homework during the summer vacation?"

"I gave you this prescription. If you make a problem with the wrong combination, I will feel bad about my conscience. Let's go! It's not too late."

"...the time is running out, you can just copy it confidently, right?" Lu Yunkai glanced at Daphne speechlessly, then shook his head with a helpless smile.

It's just that he really couldn't laugh in his heart, and he thought of a question.

Could that notebook be trying to poison himself to death?
……

"Forgetfulness? Where did you know about it?"

Professor Sprout, who was busy replacing the soil for a certain plant, looked at Lu Yunkai who asked the question in a daze.

"It's in an ancient book. It seems to be a common ingredient in potions, but I haven't found any more information." Lu Yunkai said half-truthfully.

Daphne, who followed beside her, gently tugged at the corner of Lu Yunkai's clothes.

"Oh, those medicinal materials are banned by the Ministry of Magic and are poisonous." Sprout nodded. "It was quite commonly used more than 80 years ago."

"What type of poison is it?" Lu Yunkai asked.

"It is a powerful memory repair potion with several nutrients as the main material. It was discovered by a wizard that after taking it, it will more or less cause people to suffer from insomnia, decreased intelligence and concentration." Professor Sprout patiently He explained: "And he studied [-] users who used the medicine of forgetfulness, and [-]% of them will have similar problems."

"Twenty percent? That's very common!" Lu Yunkai was a little shocked when he heard this number.

What made him even more frightened was that the poison of this grass seemed to hit his mind.

Could it be that the notebook thought that he would become stupid after taking the medicine, so that he could be controlled by it? ?
"But this kind of grass was a very commonly used potion material at that time, and it was added to many memory-related potions. The Ministry of Magic spent a lot of effort cleaning it up to prevent it from being used by others." Sprout said The head said, "I was studying in those years, and I was very impressed. My teacher was also implicated by this thing."

"Oh." Lu Yun nodded.

"However, some people said more than [-] years ago that it was not the problem of the amnesia, but the improper processing method. The amnesia just cannot be heated on the fire, and there is no problem in adding it after the potion cools down." Sprout continued, " His statement is also supported by many people, but for some reason, his discovery was deliberately forgotten."

"What's the reason?" Daphne asked curiously from the side.

"That man did a lot of bad things afterwards." Sprout shook his head.

"Could it be that the person who discovered it was..." Lu Yunkai instantly understood. "Professor, do you think his research is correct?"

"Forgetfulness itself is not poisonous. If toxins are produced during the processing, then I don't know. I only know a lot about herbal medicine. You'd better ask Professor Snape about potions." Sprout smiled Shaking his head, "But it doesn't make sense to be right or wrong. I wanted to find a plant to introduce to the students before, but I couldn't find it after searching all over England."

"Well, thank you, Professor Sprout."

Lu Yunkai nodded.He understood what Sprout said.The professor of herbalism actually supports the fact that the amnesia is not poisonous, but she can't say it directly because the Ministry of Magic requires it.

It seems that I am too sensitive?

"It's okay." Sprout still smiled gently.

Then hummed an unknown tune and continued her transplanting work.

Lu Yunkai took Daphne out of the glass greenhouse of the herbal medicine classroom.

"Yunkai, you also know that this thing is poisonous, don't do it rashly!" Daphne still had worry written on her face, and told Lu Yunkai.

"Didn't you listen to Professor Sprout? This herb is extinct. Where can I get it?"

"Others can't get it, and it's not you. You have supernatural powers." Daphne shook her head seriously, "If you become stupid because of drinking the medicine formula I gave you, I will feel guilty for the rest of my life."

"Okay! I understand!" Lu Yunkai nodded with a smile, "At least before graduation, I will ensure that you have copied some of your Potions and Transfiguration papers!"

"I didn't mean that!!"

"Oh! I see! I'm going to find Professor Snape, do you want to come with me?"

"Huh?? Why are you looking for Professor Snape? And ask about this amnesiac? Didn't Professor Sprout quite understand what he said?"

Daphne flinched when she heard that she was going to see Snape.

Unlike Sprout who was gentle and smiling towards everyone, even Slytherin students were usually afraid to see Snape's dead face.

But Lu Yunkai really didn't want to scare her, he really wanted to go to Snape to confirm again.

After all, this recipe involves Voldemort!Whether he wanted to sell Lu Yunkai a favor, or plot against him, Lu Yunkai was not sure.

"Aren't you curious about how the amnesia becomes highly poisonous if it is heated?"

"……not at all."

"Let's put it this way, if heating can make forgetfulness grass poisonous, will other materials also have this problem? If other materials are found to have similar properties, what a treatise on potions!! Write Well done, it might even be published in the Daily Prophet!"

"I don't quite understand." Daphne obviously didn't understand Lu Yunkai's idea of ​​a top student, "But... I'll go with you! Just listen to it and get some insights."

"You! Come on! Come back from Professor Snape in a while, and I'll change a paper on transfiguration for you!"

"Ah! I really didn't want to copy your thesis!!"

"Then why don't I write another article, this one for you??"

"OK!!"

"..."

****
That night, the principal's office.

"Severus, what do you want from me?"

"Principal, why didn't you undo the curse on Lu Yun?"

"He asked you to help him break the curse?"

"No, because he knows that I won't explain to him without your permission."

"He has too many secrets, and breaking the spell on him is a burden for him."

"But he's researching the anti-curse potion now." Snape interrupted Dumbledore.

"...The anti-curse potion? Can he make it?"

"It's just at the level of NEWTS. It's much simpler than the Burst and Corrosion potion." Snape said lightly, "He's already found the prescription. It's the original version. He will be able to make it tomorrow afternoon at the latest."

"Where did he find the original prescription?"

"Greengrass' daughter made a copy of his Ancient Potion Encyclopedia and gave it to Lu Yunkai."

"Where's the forgetfulness grass?"

"That's much easier to get than Phoenix's tears."

"In this case, let him solve it. This is his own choice."

"I'm not worried about the Suppression Curse itself. I'm just here to remind you, Your Excellency, if you treat him in this way again, you may create another Dark Lord."

"Don't worry, I'm prepared."

Dumbledore glanced out the window and shook his head.

"It's better like this, otherwise, many things may happen during this summer vacation." Snape's face was gloomy.
