The World's Greatest Troublemaker

"Do I just have to eat it to check? Shouldn't I prepare?"

Mok Wigun stopped Pyon Juksu, who was being unusually impatient. Although he was originally obsessed with research, his degree was excessive now. It seemed he had a strong desire to confirm something.

But if you rush because you're in a hurry, even things that would have worked out well won't. Mok Wigun first checked.

"The effects of this potion are to relieve tension and replenish stamina, right?"

"That's right. Basically, yes."

Basically. It seemed there was something more than that, and he was trying to confirm it. Although it was a bit suspicious that he wasn't talking, he must be doing this because it's not a bad thing.

"Wait a minute."

To check the effect of the medicine, you have to compare the state before and after. So you have to create a state of being a little physically tired. So that you can check if your stamina recovers.

There is a way to consume stamina in a short time. Mok Wigun moved by linking several movements. It was a method used when training the body, and it consumed a lot of stamina in a short time. As a result of exercising like that, he was covered in sweat in less than half a shichen.

"I think it's done now."

"Alright. Get in a comfortable position and drink it all up. All of it."

Pyon Juksu, as if he had been waiting, ran over and gave him the potion. Mok Wigun sat down and drank the red potion. And he focused on the sensation in his body.

"Oh. This is good."

He felt the fatigue being relieved as a refreshing feeling wrapped around his body. He felt his strength returning as the fatigue in his muscles gradually disappeared. This was a pretty good stamina potion. It seemed that if he took about the amount he had just drunk, he would recover from most fatigue right away.

On top of that, the effect of calming the mind was also good.

"It's comfortable and calming."

He had been in a somewhat excited state after moving his body vigorously, but after a while, he became very calm. A heart like a calm lake.

But when he looked in front, Pyon Juksu was watching him intently. Seeing him watching with complete concentration as if he wouldn't miss a single thing, it seemed that from now on, there was something similar to the side effect he had mentioned. It was then.

"Hmm?"

A wave of heat rose up. And he felt his body overflowing with strength and something about to burst out. He suddenly wanted to move his body and fight. And that impulse became stronger and stronger.

"What is this? Berserker's rage?"

There are such medicines or magic. That turn an ordinary person into a mad warrior who destroys whatever is in front of him. Usually, they suddenly exert a monstrous strength and fight until they run out of strength. Mok Wigun had also been in such a state before. But what he had just taken felt quite similar to the feeling at that time.

"It's similar, right?"

"Quite. The effect is a bit weak, but that's because I have some immunity to this kind of thing."

It seemed that if ordinary people ate this, they would suddenly go crazy and fight whatever they saw.

"Hey. What are you trying to feed the kids?"

"Who's feeding it to the kids? I made it, but it's a bit strange, so I'm experimenting on you in advance."

If he had fed this to the kids, it seemed a big accident could have happened.

"The effect is certainly there. Phew. As expected of my genius skills... I can't help but be amazed."

And he wrote something down. It seemed he was recording the effects.

"You're crazy. Did you call me now because you made something like this?"

"Hey. Do you not know how amazing this potion is?"

That's true. A potion with such clear and various effects is rare even in that other world. Its value as a result of research is high.

"This has its own uses."

That's also true. It will probably have its uses. But the important thing is that he needs something to use at the competition.

"You can't use it at the Heavenly Martial Arts Assembly."

"Hey. That's not what's important. Listen. I think it's because I put cinnamon in it."

Cinnamon? It's the bark of a cinnamon tree. It has various effects, but he had never heard that it had the effect of making people go crazy and fight.

"You put cinnamon in it and it becomes like this?"

"Ah. It's not just cinnamon..."

Pyon Juksu said as if he had discovered something very interesting.

"I think I need to look into it a little more, but the medicinal herbs of the Folding Snow Valley seem to be a little different."

It wasn't that it became like this just by putting in cinnamon, but that this effect only appeared from the cinnamon brought from the Folding Snow Valley.

Well, that neighborhood is a strange neighborhood. A place where the energy is gathered much more than other places. So it seemed that the medicinal herbs could have a stronger effect or a different effect than usual.

"That's a relief. If you use the usual stuff, it will just have the effect of replenishing stamina and calming the mind."

"That's right. And there's one more, try this too."

And Pyon Juksu brought another potion. This time it was also a red potion, but there were times when a blue light shimmered.

"What's this now?"

"Just try it. I'm trying to see if it has an effect on people."

He had tried it himself, and he said it had some effect.

"Is this also similar? Replenishing stamina and calming effect with something else?"

"Oh. That's right. But it will be a little different from the one before."

He was a guy who did a lot of strange things anyway. But that's probably why he was able to have the skills and knowledge he has now. If you just follow what others do as you always have, you'll always stay in the same place. You have to do something different for a change to happen, whether it's good or bad.

"Alright. Wait. I'll use up some strength."

Mok Wigun did the exercise he had just done again. Just by doing a few movements in a row, a huge amount of stamina was consumed.

"Alright. Bring it."

"Here. Here."

Pyon Juksu ran over quickly. This time too, Mok Wigun drank the potion in one go.

"How is it?"

"Wait. I just drank it, what..."

This potion was also effective. But this time, the calming of the mind came first. He became comfortable and a little drowsy. It seemed it would have a good effect if he drank it when he was very tense or couldn't calm down.

And then vitality circulated in his body. A feeling of life and strength welling up. He would have had to give a lot of gold to buy this in that other world. It was that effective.

"This time, the calming comes first, and the stamina filling comes next."

"That's right. And is there anything else?"

He thought there was nothing special. So he was concentrating his senses more keenly, but finally, another effect appeared.

A wave of heat rose up. But this was different from the heat before. Should he say the one before was bloodlust? If it was a feeling of longing for blood, this one was different. The center of a man became taut, burly, and energetic.

Mok Wigun stood up and grabbed Pyon Juksu's collar.

"Hey. You bastard. Are you going to keep doing this to what you're feeding the kids?"

"No. No. This is not for the kids."

Pyon Juksu hurriedly waved his hands and made an excuse.

"Cinnamon had a special effect, right? So I experimented with other things a little. But the effect of this was amazing."

"What did you put in it to make it like this?"

As the center became large and hard, he felt a strange feeling. Should I say it was a feeling of pride and also a feeling of shame?

"Three-leaf nine-leaf grass."

"Isn't that epimedium?"

Three-leaf nine-leaf grass is also called epimedium. It has been famous as a medicinal herb good for nourishing and strengthening since ancient times.

"That's right. This was the most effective."

Pyon Juksu smiled slyly, saying that it also worked on people. And he looked at Mok Wigun's center and wrote something down.

"Hey. What are you writing?"

"I'm just recording it. That it was effective."

And he added.

"Stay still. I have to see how long it lasts."

"Hey. You bastard. Find something to increase the kids' internal energy in the time you're doing this! If you keep doing this, I won't give you research funds. I'll also confiscate all the medicinal herbs."

At Mok Wigun's scolding, Pyon Juksu said as if he was a little wronged.

"I came up with this while doing this and that to find something like that. What. Do you think something like that just comes out of nowhere? You have to try this and that, and if you fail, you try something different. And then it comes out."

The guy's words were not entirely wrong. But this probably didn't come out while doing this and that. It feels like he made it with determination because he was curious.

"Then did you find something to increase internal energy?"

"Huh? Internal energy?"

"Yes. You said it came out while you were doing this and that to increase internal energy."

"Aha. I tried putting in three-leaf nine-leaf grass at first."

See. He did it with determination. When Mok Wigun's expression changed, Pyon Juksu said urgently.

"That. This is very profitable. Think about it. If you say you're selling this, people will line up to buy it even if they have to pay a thousand gold."

"Forget it. I have enough money. Just take care of the kids."

"Phew. This guy has no business sense. If you tell Yi Jeong-gi or Yuk Samcheon about this, they'll go crazy."

Thinking about it, it seemed it would be useful. Not to mention the merchants, but how many high-ranking officials and royal family members would need this? So it would be very good to use it when you need help or to build a friendship.

"Alright. Still, since it seems useful, I'll forgive you."

"Then you'll leave the research funds and medicinal herbs as they are, right?"

"Yes. I'll let it go this time."

"Phew. That's a relief. And this is really amazing for a man. You'll need it someday too."

"Shut up. You bastard."

Pyon Juksu, whether he did or not, sang a song, saying he wouldn't have his research funds and medicinal herbs taken away. And then he went to one side and brought dozens of small bottles.

"What's this?"

"It's the one from before with the Folding Snow Valley cinnamon taken out."

He said he had only put in regular cinnamon. Just in case, Mok Wigun opened one and drank it.

"Hmm. This is good."

His mind and body were calmed, and his fatigue was relieved.

"The kids don't have much time left, so use this. Then you can train even harder."

"I see. From today, I'll have to increase the training time. And also increase the concentration during training."

Pyon Juksu muttered that he could hear the kids dying and then said.

"But what are you going to name this?"

"Hmm... Cheongsim Hwallyeoksu?"

A name that directly shows the effect. Pyon Juksu said it seemed fine.

"But if it's for the competition, it doesn't have to be this good."

"Is that so? Hmm... Then I'll just dilute it a little."

They decided to decide how much to dilute it by experimenting, and Mok Wigun took the medicine bottle and headed to the training ground. And so, Cheongsim Hwallyeoksu was first introduced to the world.

* * *

"Young master. Please give me some of that too."

Gu Mungoe staggered and approached Mok Wigun. He begged for just one Cheongsim Hwallyeoksu.

Mok Wigun had only given it to the disciples and not to the Light Wind Unit. At that, the Light Wind Unit became distressed. The disciples, even when they were tired, came back refreshed, so only the Light Wind Unit who were facing them were dying.

"I think I'm going to die. Please give me that too."
