Evolution of Slime to Peak

"What the hell are you guys doing?!"

A roar came out from the middle-aged man who was burly. His muscle flexed as his brows knitted.

"I didn't realize the innkeeper pack some muscles."

Ren murmured slightly stunned.

"Yeah, he always hides it and only shows his muscle when there is trouble. As far as I know, he was a former A-rank adventure."

"A...Adventure?"

Ren tilted his head.

"Yeah, you don't know. Adventure guild issue quests and requests and adventures complete them to earn money. Isn't it a fact?"

The girl was confused seeing the lack of knowledge in Ren.

Ren's eyes shone.

'Adventure Guild! I should check that!'

Nodding himself, he looked ahead.

The troublemakers' faces were swollen and they were kneeling on the floor.

"Don't make trouble here again." The innkeeper warned.

"Yes!" Both of them shouted.

Clap! Clap! Clap!

The customers clapped and smiled.

"As expected of the boss."

"Yeah, no one can make trouble here!"

"You are quite strong." Ren walked in front of the innkeeper.

He didn't realize but there was a red exclamation mark hovering on the innkeeper's head.

As he focused his gaze there, a small window popped out.

[Danger Level: High]

[Probably Can't Escape Easily]

The danger level made Ren tilt his head.

'...'

He decided to quiet down and sat at the table drinking soup and chewing chicken meat. There was a variety of food here. The meat of boar, wolf, etc, as well as vegetables. Fry, Soup, Curry, etc food varieties made Ren satisfied as he could taste new dishes every day.

When he checked his wallet, he only had some gold coins left.

"Time to head out."

He stretched his arms and moved to the door.

"Going out this late?" The innkeeper asked.

"Yes. I want to eat some fresh air." Ren replied and smiled slightly.

He exited the inn and looked at the surrounding.

Lights had filled the street. Every house was illuminated with bright light, there wasn't that place that was dark.

Ren jumped and landed on the roof. The combination of small and big houses stunned Ren slightly as he had never seen this kind of building.

The buildings were unique and all looked beautiful. The varieties of color and the natural glow would attract anyone. But the locals were locals, so they were used to this.

He moved at the night like a thief, like an assassin. He didn't need to sneak, but he just wanted to do that.

Also, being in a high place showed him more of the city than he would see from the ground.

In the middle of the city, just some further from the fountain, a big building was there. It was bigger than any other building, so it attracted Ren's attention.

He reached near the building and stare at it.

Adventure Guild.

This was written in big words with style on a huge signboard. There was some light inside the building, but most of its floor was filled with darkness.

It had four floors and only its first floor was lit, other floors were covered in darkness. Ren wanted to visit the building but decided not to.

"I will come here tomorrow."

He returned to the inn. The innkeeper greeted him.

"Good night...Boss?" He decided to call him boss as he heard others calling him that.

"Haha. Good night." The boss chuckled a bit.

Ren walked to the room and jumped on the bed. Feeling the comfy pillows, he fell into a deep slumber.

As he was sleeping, a screen appeared. The human system that every human has processed. And he had got his personal one.

It wasn't that special, but he didn't get this system when he ate bandits.

As the system mysteriously appeared, Ren's body changed slightly.

His body glow and transformed into slime.

__________

Next Morning-

"Hmm~" Ren woke up. He tried to stretch his arms, but he failed to do so. As he looked at the door, the door looked bigger than previously.

When he looked at his body, he realized he had transformed back into the slime.

"Wut?"

He was confused. He tried to process the information.

"So, I transformed back to smile. Now, how do I turn back to being human." As he was wondering, a system greeted him.

[Human System - A system gifted by the gods to humans.]

"H-Human... System?" He stared blankly at the window. Another screen appeared and he got to look at his strength.

"I... I am only C-rank..."

He frowned. He didn't see hidden skills.

"Well anyway, from the skill description, it says I can transform at will..."

He shouted 'Transform' inside his head. A puff sound echoed and his body grew back to human. His body was covered with the slimy thing that soon turned into clothes.

"Whoa."

As he was using his skill, suddenly an idea hit his brain.

"Wait... Can't I try to... create my own skill?"

...

Inside the quiet room, Ren banged his head on the bed and began manipulating his mana.

"Now, let's begin the experiment!"

He mumbled to himself.

But...

Growl~

His stomach cried.

Ren stopped and stood. He went down to fill his stomach with tasty food.

When he went down, the sweet smell of food drifted to his nose. Licking his lips, he walked to the room and sat on the chair.

Eating boar meat and mushroom soup, he was satisfied.

He returned to the room and seriously continued his experiment.
