Hogwarts Kryptonian

"Yunkai, what's wrong with you?"

"nothing much!"

"You said it was nothing! You've been here giggling for a long time."

"sorry!"

Lu Yunkai scratched his head in embarrassment, and then handed Daphne a parchment roll placed next to the crucible.

"...What?" Daphne was stunned.

"You came to me for a paper on transfiguration, right?"

"I'm just going to take a look and not copy it." Daphne's face turned slightly red and she took the parchment roll.

"You say that every time. Professor McGonagall had to read our thesis together last time." Lu Yun gave Daphne a white look, "You should change it a little bit."

"I know!!" Daphne became even more embarrassed and could only change the subject: "What kind of medicine are you taking?"

"this."

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

However.

Daphne glanced at it.

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

"The book you gave me contained this recipe?" Lu Yunkai was stunned.

"Yes! I remember it very clearly." Daphne nodded and pointed at the parchment, "Especially this one, the forget grass."

"Well, this forget grass is quite beautiful..."

"Yunkai! You'd better not be worthy of this thing." Daphne turned over Lu Yunkai's parchment, then looked at Lu Yunkai and said seriously.

"Ah? Why?"

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

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

He looked at the shadow in front of him.

[Forget grass: an ornamental plant. Four Gallons per plant. 】

The system didn't say it was poisonous! !

"I'm not lying to you!" Daphne nodded seriously.

"But..." Lu Yunkai glanced at the shadow again.

He didn't know who to trust.

"How about you ask Professor Sprout?" Seeing that Lu Yunkai didn't believe it, Daphne could only continue: "Don't prepare this medicine yet!"

"...It's okay, let's boil the potion first, and I haven't bought the amnesia yet." Lu Yunkai lied and secretly collected the amnesia that he had chopped up next to him.

"Of course you can't buy it. You can't buy forgetfulness 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 stood up immediately.

Can’t buy it in the whole of England? No wonder this thing costs four gold galleons for a broken grass! In terms of potion materials, this is already at the ceiling level.

It’s almost catching up with the price of Phoenix Tears.

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

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

"I gave you this prescription. If you mix it up randomly and something goes wrong, I won't be able to bear it in my conscience. Let's go! It won't be long now."

"...You don't have enough time, so you can just copy it confidently, right?" Lu Yunkai glanced at Daphne speechlessly, and shook his head with a helpless smile.

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

Could that notebook be trying to poison yourself?

…

"Amnesia? Where did you know that?"

Professor Sprout, who was busy changing soil for a certain plant, looked blankly at Lu Yunkai who asked the question.

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

Daphne, who was following behind, gently pulled the corner of Lu Yunkai's clothes.

"Oh, that's a medicinal material banned by the Ministry of Magic. It's poisonous." Sprout nodded, "It was still commonly used more than eighty years ago."

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

"It is a powerful memory repair potion composed of several nutritional supplements as the main ingredient. It was discovered by a wizard that after taking it, it will cause more or less insomnia, decreased intelligence and concentration." Professor Sprout patiently explained: "And he studied 30 users of amnesia potions, and 20% 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 sanity.

Could it be that the notebook was thinking that he would become stupid after taking this medicine so that he could be controlled by it? ?

"But this kind of grass was a very commonly used potion material at that time. It was added to many memory-related potions. In order to prevent it from being used by others, the Ministry of Magic spent a lot of effort cleaning it up." Sprout pointed out. Tou said, "I was studying in those years, and I was particularly impressed. My teacher was also implicated because of this thing."

"Oh." Lu Yunkai nodded.

"But in fact, more than fifty years ago, some people said that the problem is not with forgetfulness, but with improper processing methods. Forgetfulness just cannot be heated on a fire. There is no problem when adding it after the agent has cooled." Sprout continued, " There are many people who support his statement, but for some reasons, his discovery has been deliberately forgotten. "

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

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

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

"Amnesia grass itself is not poisonous. If toxins are produced during the processing, then I don't know. I only know a lot about herbs. You'd better ask Professor Snape about potions." Sprout smiled. Shaking his head, "But right or wrong is meaningless. I wanted to find one to introduce to the students before, but I searched all over England and couldn't find it."

"Well, thank you Professor Sprout."

Lu Yunkai nodded. He understood what Sprout said. The herbology professor actually supported that forgetwort was not poisonous, but she couldn't say so because the Ministry of Magic required it.

It seems that I am too sensitive?

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

Then humming an unknown tune, she continued her transplanting work.

Lu Yunkai took Daphne out of the glass greenhouse of the Herbology classroom.

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

"Didn't you hear what Professor Sprout said? These herbs are extinct, where can I get them?"

"No one else can get it, and it's not you. You have great powers." Daphne shook her head seriously, "If you become stupid because of drinking the potion formula I gave you, I will feel guilty for the rest of my life."

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

"That's not what I said!!"

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

"Huh?? Why are you asking Professor Snape? Are you asking about this forget grass? Didn't Professor Sprout make it quite clear?"

Upon hearing that she was going to see Snape, Daphne flinched.

Unlike Sprout, who was gentle and smiling to everyone, Snape had such a deadly face that even Slytherin students were usually afraid to see.

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

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 the reason why forgetfulness becomes highly poisonous if it is caused by heating?"

"……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 great potions paper this would be!! Well, it might even be published in the Daily Prophet!"

"I don't quite understand." Daphne obviously didn't quite understand the idea of ​​a scholar like Lu Yunkai, "But... I'll go with you! Just listen and learn more."

"You! Okay! Come back from Professor Snape later, and I'll revise a paper on Transfiguration for you!"

"Ah! I really didn't do it to copy your paper!!"

"Then how about I write another article and give this one to you??"

"OK!!"

"..."

****

That night, the principal's office.

"Severus, do you have a problem with me?"

"Principal, why don't you give Lu Yun the unblocking spell?"

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

"No, because he knows that I won't give him a solution without your permission."

"He has too many secrets, and it will be a burden for him to unravel the spell on him."

"But he is currently working on the anti-curse potion." Snape interrupted Dumbledore.

"...curse-breaking potion? Can he make it?"

"It's just the level of NEWTS. It's much simpler than the explosive corrosive potion." Snape said calmly, "He has already found the prescription. The original one. He can make it by tomorrow afternoon at the latest."

"Where did he find the original prescription?"

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

"Where's the forget grass?"

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

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

"What I'm worried about is not the Spell itself. I'm just here to remind you, Mr. Principal, if you treat him 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 best this way, otherwise a lot of things may happen during this summer vacation." Snape's face was gloomy.
