The Fastest Evolution of the Unrivaled Slime: My Rejected Skill was a Cheat for Super Efficient Leveling, So I Trained 100 Times Faster to Become the World’s Strongest

“What? N-no way…”

“That’s right. Brace yourself.”

Grabbing Wakame Man’s arm, I raised my fist high.

“!”

“GYAAAAAAHHHHHHHHHHHHHHHHHH!!”

An explosion engulfed Wakame Man’s body, radiating an intense light. Black smoke sizzled upward from his frame.

This guy can be killed over and over. In other words, he’s an endless source of experience points.

In PvP battles, you can’t gain experience since you don’t actually kill. But with him, it’s different.

So far, I’ve killed him three times. Considering the XP spent, I’m getting about 1000 XP per kill.

This is more efficient than I thought. Well then, I’ll farm as much XP as I want until his spirit breaks.

“!”

With another explosion, Wakame Man’s body was blown away. That makes four times.

Oh, looks like upgrades come as a bonus. Not bad at all.

“You monster! Don’t you have a shred of humanity!?”

“Why would a monster have that?”

“AAAAHHHHHHHHHHHHHHHH!!”

How much time has passed? After countless explosions, the only sound left echoing in this underground hallway was soft sobbing.

“S-sniff… I can’t take it anymore… Someone, help me…”

Looking at Wakame Man sprawled on the floor like a discarded mop, I decided to check my status.

Several upgrades and a lot more XP earned. Way better results than I expected.

“You heartless monster! How can you kill someone so easily!? Don’t you have a heart!?”

“You sure flip-flop fast between calling me a human and a monster. Make up your mind. By the way…”

I grabbed Wakame Man by the head and lifted him menacingly. He let out a small squeal.

“Still want to go? I don’t mind either way.”

“N-no! You can pass! Just don’t attack me anymore! I don’t like pain!”

“Fine, then.”

I released him and proceeded down the hallway.

“You coward! Someone like you will end up in hell soon!”

As Wakame Man’s bitter words echoed down the hall, Vitt and I moved further ahead.

“You know… you’re pretty ruthless.”

“Don’t care. He started it. Anyway, why are you tagging along if you’re not ready for this?”

“I dunno. Just feels like I shouldn’t leave you alone. Feels like the right call.”

At first, I thought about ditching him after getting directions.

But Vitt was persistent, and somehow, I found myself relying on him.

It’s strange. I’ve never felt this way about someone before. Maybe I’m changing, too.

“…We’re here. This must be it.”

Lost in thought, I hadn’t realized how quickly we’d arrived. Ahead of us stood a large iron door, looming heavy and foreboding in the dim hallway light.

Beyond this door lies the experimental subject—a child. I wonder what they’re like.

Will they be unable to communicate, like I was not long ago? …No point in speculating.

I activated , shattered the door, and took in the scene beyond.
