“Huff, huff”

At the training ground of the Duke of Levonsuit.

There was one unfit person at the place where the knights of the family trained their bodies.

“Run faster. You look like an ant crawling.”

“Huff, huff”

The person’s name is Aslan Levonsuit.

The only daughter of the family was now sweating as she’s running on the training ground.

“Your pace is slowing down. Come on, run faster!”

And a man walking with his arms folded while shouting was behind Aslan.

Bertrand Schumann pushed Aslan without mercy.

“A turtle would be much faster than this! Where’s your dignity as a human? You’re worse than an animal!”

“Huff, huff”

‘It’s not me who’s worse than an animal, it’s you! You devil!’

She wanted to answer back, but Aslan couldn’t speak out.

Because her vocal organs had already lost all freedom due to her respiratory system.

‘Lord, I think I’ll die!’

I remembered the expression ‘ran so much that their mouth smelled burnt.’

Is that really possible?

‘S, save me.’

It wasn’t that much of a run.

She only ran two laps now, but her stamina was already exhausted on the first lap.

“Huukk!”

Aslan, who fell down with a strange scream, gasped for breath.

She felt her lungs throbbing and heart pounding like it was going to burst.

Her legs were already hot and pounding, and it felt like it would really explode as if it had become a bomb.

“Only two laps. Your stamina is weaker than I thought.”

Bertrand carried her on his shoulder like a pack and headed to the shade of the tree.

Is it break time?

Half passed out, she expected a honey-like break, but it was just another pain that came to her.

“Oh!”

“Don’t spit it out. Drink it all.”

What she saw soon as she opened her eyes, was a flask bottle with a long opening.

There was a black liquid inside, covering Aslan’s nose, Bertrand shoved the bottle into her mouth.

I can’t breathe.

If I want to live, I have to drink it all.

“Eughh……”

The black liquid in the bottle went down her throat.

As soon as it touched her tongue, Aslan’s senses flashed and her body twitched.

‘Wha, what the hell is this?!

Taste? It doesn’t even fall into that category.

I only felt pain, not taste.

The pain as if it’s crushing your tongue and burning your throat.

I forcefully handed it over, but her stomach that received the liquid was sore and painful as if it were protesting.

“Cough! What the hell is that?”

“It is a liquid made by grinding various ingredients that are good for the body. Not only does it wake you up, but it also increases your muscle’s recovery speed.”

“Ugh. But I can’t do it today anymore……”

But at that moment, the pain she felt all over her body disappeared.

“Well, muscle recovery should take at least a day. Instead, it also serves as a pain reliever. Try to get up.”

“Really…… It doesn’t hurt?”

All the running she did on the training ground earlier felt like it was all just a dream.

I can move more with this.

But Aslan, who has knowledge about working out, turned to Bertrand.

“But isn’t it bad if you work out too hard? I heard that if you work out too hard, your muscles will melt. Even if I just drank it, I heard it takes about a day to recover.”

The name of the disease Aslan referred to was Rhabdomyolysis.

It is a disease in which muscle cells disintegrate after a sudden excessive exercise by a person who does not usually exercise.

When muscle cells disintegrate, they all go to the kidneys.

And when they pass through the kidneys, the kidneys fail to function.

This results in brown urine, and due to broken kidneys, people die of kidney failure or several other diseases.

“Hmm. Well, there’s a disease like that.”

The scariest thing is that people who do it suddenly are often the ones who catch such a disease, than those who exercise a lot.

Since high-intensity exercise, which burns calories in a short period of time, such as CrossFit and spinning became popular in the modern world, the number of patients with this disease has increased.

If an untrained person performs the aforementioned high-intensity exercise, they will suffer from rhabdomyolysis and will be put into the hospital.

In the first place, Aslan learned of the disease because she heard from her nurse unnie that many people were taken to the hospital after exercising excessively to prepare for the summer season.

“But didn’t I tell you? Your mana is special. Your mana will already be involved in it before your muscles thaw. No matter how hard you try, you will never catch the disease you mentioned. It’s hasn’t even been an hour, so you won’t feel much.”

Bertrand answered Aslan’s question with an expressionless face.

“In a few days, you will be able to see yourself becoming stronger and very healthy unlike now.”

“……Okay.”

“Alright, then run.”

“But how much longer do I have to do this?”

Bertrand opened his palm. As soon as she saw all ten fingers spread out, Aslan’s expression became serious.

“N, no way! Ten laps?”

Bertrand shook his head.

Aslan’s expression turned pale.

“T, then hundred laps?”

Bertrand shakes his head again.

And soon, he answered directly.

“Ten hours. Regardless of the number of the laps.”

There was a smile on his face again.

“You didn’t know? Don’t worry because you’re not going to die.”

The devil had a smile that could make someone cry.

“It’s only painful enough to make you want to die.”

***

“Huu huff huff”

Aslan who barely managed to return to her room sat down.

She couldn’t even go to bed because her legs were swollen and her head was dizzy.

‘This is torture. It’s not class, it’s torture!’

She really ran on the training ground for ten hours.

In the middle she could no longer bear the pain even with the potion, so she sat down. But Bertrand didn’t have any mercy.

‘Come on, get up. I’ll hold your hand, then keep running!’

She ran on the training ground holding hands with her favorite character from the game.

It was a romantic situation, but the reality was not romantic at all.

‘Am I a luggage!’

Bertrand ran without worrying about Aslan being dragged by his hand.

How dragged I was, the shoes I wore today became a complete mop.

Nevertheless, the class never ended until ten hours later.

‘I think I’m going to die. No, I will die.’

All I did was run, but it wasn’t just my legs that were hurting.

I was so breathless that my lungs seemed to hurt, and my back also hurts.

Unexpectedly, running also puts pressure on the waist.

‘That devil! He even dealt with father!’

Leon witnessed Aslan, who was tortured under the guise of exercise.

He was the head of the Duke’s family and loved Aslan very much, so he naturally stepped forward, but Bertrand stopped him with great force.

‘The lady has great talent. If she doesn’t do this, that talent will be put to waste. Does his grace want to block his daughter’s future?’

As if he had become a snake in front of a frog, Leon went back without saying anything.

His cheeks were wet with tears that seemed to express his love for Aslan, but it didn’t help at all.

‘The rye…..’

Naturally, she couldn’t eat her own diet anymore.

All diets have been replaced with that terrible liquid brought by Bertrand.

‘I replaced your meal with this liquid four times a day. No need to worry about nutrition, because it contains all the essential nutrients. There is no better food than this for muscle production and fat breakdown.’

Don’t call it food!

It’s poison!

The diet I used to eat is a million times more delicious than this!

Of course, it’s a secret that I couldn’t even say anything because he said something at the moment I tried to argue.

‘You’re staying here for half a year?’

Bertrand said that the class period is exactly half a year.

He said he would stay here for the next six months and hold classes with Aslan.

It’s also a super hardcore schedule starting at 6:30 in the morning!

Aslan, who had to keep up with the schedule was still lying on the floor.

‘Haa. Haa. I have to get up……’

I have to sleep in bed to sleep well!

But in the end, Aslan gave up and left herself on the floor.

‘I’ll take a little rest and go back to bed.’

Thinking so, Aslan closed her eyes for a moment.

At that moment, suddenly a tremendous shout was heard.

“Wake up!!!”

“Huh?”

As soon as she woke up, she saw Bertrand in her room.

“T, teacher? What are you doing in my room?”

“It’s time for class. Get up quickly.”

“No, I haven’t even slept yet. What time is it now?”

“6:30 in the morning.”

“What?”

At that, Aslan looked at the clock in the room.

It was really 6:30 in the morning as Bertrand said.

‘No, what is this? D, Did I really sleep?”

I’m sure I just lied down for a minute and closed my eyes?

But I fell asleep?

I don’t think it has passed even a second?

No matter what she thought, Bertrand grabbed her and led her away.

“Oh, my body still feels……”

“You don’t think it has recovered?”

The moment she heard it, Aslan realized.

Her body doesn’t hurt at all.

“Huh? My body…… It doesn’t hurt at all.”

“Didn’t I tell you? The potion I gave you increases the resilience of the muscles. In addition, your enchancement mana must have permeated your muscles, so you’d be stronger than yesterday.”

As soon as he finished speaking, Bertrand threw a thick book to her.

Aslan until yesterday would have staggered even if she received it with both hands, but now, surprisingly, she received it with one hand easily.

“I, is this for real?”

“Hmm. That’s amazing. You haven’t even done upper body exercises yet. Are your arm muscle strengthened?”

“…… So you thought I wouldn’t be able to catch it?”

“Yes, I was thinking of aiming it on your forehead to wake you up.”

This man is a real devil.

A master-class devil!

T/N:

The surname is originally Levonsuit, I made a mistake with Aslan’s surname. I’m so sorry.(๑′̥̥̥▵‵̥̥̥ ૂ๑)

So yeah, her surname is going to be Levonsuit starting now.
