Invincible Mumu

happens, you won’t have to worry about this after that.
Would you be satisfied with this?”

At that, Mumu nodded with a sullen expression.

As the man said, he couldn't do something which could cause trouble to Jin-hyuk and to his life in the Academy.

“Good.
Then let’s get back to the other talk?”

“What?”

“Becoming a disciple of mine.”

“Disciple?”

“This isn’t a privilege that one can easily get.
If you become a disciple of mine, I will make sure that you are at third rank by the end.”

“Third rank?”

“Right.
Do you know what that means?”

If one graduated with the first, second, and third rank at the Academy, great honor and wealth would follow.

One could even become an official of the Imperial Palace.

Everyone would want that.

‘How is that? Is this interesting?’

If anyone said such a thing, it was bound to be tempting.

Even a pure guy like Mumu could want it.

Mumu answered.

“This rank… mister… no, deputy head, if I become a disciple of yours, I might be a third ranker?”

‘Caught you!’

He thought that this proposal would make Mumu tempted to accept it.

He smiled and said to Mumu.

“Didn’t I say that this opportunity isn’t easy to come by? If you don't get high grades by the mid of the second year, you won't be able to get a dedicated teacher.
However, I value your talents which was why I suggested this to you.”

In a word, it was like an honor.

At that, Mumu tilted his head and asked.

“Isn’t this against the rules?”

“Huhuhu, taking that into consideration too, I am willing to accept you.
All the responsibility will be borne by me, so don’t worry…”

“Ahh.
That's all right.
You don't have to do that; it is fine.”

“Right.
Wh… what?”

Dan Pil-hoo frowned at Mumu’s words.

It was fine?

“My father said that I shouldn't cause trouble for others for my sake; I don't think it is nice for the deputy head to be held responsible for me.”

Mumu always kept in mind the things Yu Yeop-kyung said.

At those words, Dan Pil-hoo coughed.

“Cough cough.
Didn’t I say that you don’t have to worry? You only need to receive the teachings…”

“That is one reason, but there is also another reason.”

“Another reason?”

“I am already training.”

This was his first-time hearing something like this.

What kind of training would a guy with no knowledge in martial arts even do?

“I heard that you trained yourself, but what kind of training could you even have?”

Mumu smiled and answered brightly.

“Muscle training.”

“…”

And he snorted.

Muscle training.

Refusing the offer was one thing, but it was absurd to use this as an excuse to refuse him.

‘Ha…’

With that, Dan Pil-hoo was wondering if he should push him further or not.

If Mumu was the clever kind who was trying to pull his strings, then Dan Pil-ho would have gotten angry.

But Mumu was really naïve.

‘… it would be better to appease him.’

Finding someone like Mumu within the Academy was rare.

Dan Pil-hoo tried to make a very soft, caring expression and said.

“Muscle training… that is the first I have heard of it.
Then can you tell me under whom you studied it?”

“Nobody has taught me muscle training.
I myself am the teacher and the disciple.”

“…”

Wasn’t this the same as self-training?

At those words, Dan Pil-hoo was nearing his limit.

This guy was pure, but he was too pure.

However, since the kid had talent, he decided to be patient a little longer.

“Wow, I think it's amazing and wonderful that you’ve reached this level just by training your muscles.
But that has a limit.”

“Limit?”

“Why do you think warriors learn martial arts to kill or subdue the opponent? It is all about getting stronger.”

“Muscle training too…”

“Let’s keep the jokes aside.
Simply training the body won’t give you results of that level.”

Shh!

Dan Pil-hoo held out his hand and pointed towards a small tree.

As if a sharp blade cut it, the tree fell down.

Slash!

Mumu was shocked by the falling tree.

“How did you do that?”

Dan Pil-hoo shrugged his shoulders and asked.

“That is sword energy.
When you train your internal energy and have a strong understanding of the energy flow, you can use your energy in this way.”

“Amazing.”

“Amazing? This is not so shocking.
If you become my disciple, you can learn anything.
However, training muscles won’t be enough.”

Once one sees this, they would want to learn it at all costs.

After talking this much and showing this in person, if Mumu still insisted on muscle training or came up with another reason to refuse, then he had to be stupid or just beyond innocence.

Dan Pil-hoo approached Mumu and put his hand on his shoulders.

“If you follow the teachings of mine, you can reach this level too.
No, I will make you stronger than the headmaster.”

He thought that he conveyed everything to Mumu.

However, Mumu tilted his head and said something incomprehensible.

“I… have a question.”

“Go on.”

“I hope you don’t feel bad.”

“You think a question will make me feel bad? Ask anything.”

“Really?”

“Yes.
Anything.”

“Thank god.
I was curious to know why the deputy head kept on asking me to be your disciple even though your muscles are so weak?”

“… what?”

Da Pil-hoo doubted his ears.

He was wondering what Mumu was going to ask, but did he just say that his muscles were weak?

This was beyond absurdity, especially from an idiot who knew nothing about Murim.

“Haa…”

Dan Pil-hoo closed his eyes and placed his hand on his forehead.

Words didn’t seem to work anymore.

Only the body will work for…

Thud!

‘Huh?’

Dan Pil-hoo’s eyes shot open at the sound.

As he looked at the strange scene.

Mumu's arm muscles expanded first, and then the clothes were torn, and his upper body enlarged.

‘!?’

The bulging muscles on Mumu’s body were squirming as if they were alive.

At those incredibly developed muscles, Dan Pil-hoo was at a loss of words.

He felt the body of Joo Kang-in, a member in the training center, who was known to reach extreme levels in working his body was a dwarf in comparison.

‘How can the body suddenly…’

He had never seen such muscles in his life.

With such muscles, just looking at it was taking away his breath.

At that moment, Mumu pulled back his right arm.

And clenched his fist, ready to punch ahead with the biceps which swelled.

“What are you trying to do?”

Feeling crisis, Dan Pil-hoo opened the distance between them and raised his internal energy.

And then was ready to unleash sword energy at Mumu.

‘How dare he do this to me!’

However,

Chachachacha!

The moment the sword energy was released at Mumu’s chest, it scattered like haze before touching the chest.

Dan Pil-hu’s eyes widened at that.

The kid didn't learn martial arts, so he couldn't use internal energy, then was the sword energy offset by mere muscles?

“What the hell…”

It was before he could express his doubt.

Mumu clenched his fist and then made an action of punching Dan Pil-hoo from afar.

“Ugh”

Swoosh!

His eyelids started fluttering at the tremendous wind pressure coming at him, and it was as if a storm had taken birth right in front of him.

Even his ears were hurting at the sound.

“…”

Dan Pil-hoo felt a cold sweat drop down.

He looked at the fist of Mumu.

It was his first time in life that he was gripped with fear that his face could be blown away.

As he gulped, he heard a rumble behind him.

Thud!

Scared, he slowly turned his head.

‘!!!!’

There, bushes, trees, and plants were all uprooted and thrown away.

‘… no!’

This wasn't power from internal energy but muscles.

Was this all done with the force of a fist?

It was the moment when his common sense had shattered.

Mumu said to him, who was at a loss of words, with a bright and innocent smile.

“Train your muscles.
Even the deputy head can do this much.”

‘… this much?’
