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

146. The Sisters’ Duel

Sierra readied her sword with a solemn expression, and Laura lunged at her with ferocious intensity.

It was a sudden, almost explosive charge. Her movements had slowed, but she was still faster than most monsters, and much more savage.

Laura swung her sword downward with great force. The blow came down like a waterfall, and Sierra—

“Activate!”

She swiftly responded, slashing with her magic sword. The moment their blades clashed, the magic sword exploded.

The explosion was laced with lightning, striking Laura’s body. The lightning magic imbued in the sword had activated.

Its power was enough even for Laura, and she froze for a brief moment under the shock of the lightning.

“Uwaaahh, aaaahhh!”

Laura, letting out a cry that bordered on a wail, sensed the danger and retreated. She crouched low, glaring at Sierra.

Sierra didn’t miss this opening. She switched to the red sword at her waist and advanced even further.

Laura wasn’t about to lose, rushing forward with a storm of slashes.

Sierra calmly deflected each one. Their blades clashed, and the metallic sounds echoed across the field.

“Activate!”

Again, Sierra detonated her magic sword. Flames erupted from her blade, disrupting Laura’s stance.

“Uwaaaahhhh!!”

Engulfed in flames, Laura screamed in even more agony. There was no doubt she had taken considerable damage.

At a glance, it seemed Sierra had a clear advantage. But in reality, that wasn’t the case.

Sierra now only had her blue sword left. When her magic swords exploded, they shattered completely. If she lost her swords, Sierra would be unable to continue fighting.

It was too dangerous to hand over another sword now. So, once Sierra was disarmed, I would have to step forward and fight.

When that time came, I would have no choice but to attack Laura seriously. That moment was fast approaching.

“Uwaaahh! Aaaahhh!!”

Laura screamed in pain, thrashing about. Sierra watched her quietly, then reached for her last sword.

“…It hurts, doesn’t it? Laura, your big sister will take care of everything.”

“Uwaaaahhhhhh!!!”

Laura let out her most pained scream yet. I noticed that the sword she was gripping was glowing white.

“That’s— !”

It was Laura’s ultimate technique. She still had enough strength to use it!?

If that hit Sierra, she wouldn’t stand a chance. I had to pull her back immediately!

“Sierra!”

As I called out, I realized something. Sierra hadn’t taken a single step back.

“So that’s Laura’s true strength. Then— I’ll show you mine. With this one and only technique I’ve mastered.”

The white light from Laura’s sword intensified, swelling to explosive levels. Sierra took a deep breath and locked eyes with Laura.

“Uwaaaahhhhhh!!”

“!”

At first glance, it seemed like just a simple downward strike.

But Sierra had perfectly timed the attack after observing Laura’s charge. It wasn’t just a strike—it was a technique.

The ice-imbued slash sent Laura’s sword flying into the air with a loud explosion.

Her sword danced through the sky, seeming to be swallowed by the azure heavens.

Sierra sprinted toward the now-unarmed Laura and—

—wrapped her tightly in her arms.

“I’m sorry, Laura. It must have been so hard for you. Even after I ran away, you kept fighting, didn’t you?”

“Aaahhh, aaahhh!!”

Laura thrashed, but Sierra held her close. It was a gesture filled with kindness, as if soothing a wounded animal.

“Big sister!”

Next, Fran rushed in from behind and embraced Laura.

In the middle of the field, the three of them held each other, with Laura at the center.

“I love you, Laura. I always have, and I always will. I’m never running away again. So, you don’t have to suffer anymore.”

“…I…”

Laura spoke in a trembling voice. Sierra and Fran looked up at her, startled.

“Will I… be okay? If I stay with you, won’t I take away your happiness?”

Laura was crying. Her shoulders trembled, not from the berserk state, but from her tears.

“Father said it was my fault you disappeared. That because I was happy, I stole your happiness away.”

“That’s not true! Because… being here, with the three of us together, that’s what happiness is.”

Laura responded to Sierra’s tearful words with a hug. Only the sound of their shared sobbing echoed gently across the field like ripples in the wind.

“…I see. So, I’m allowed to be happy too.”

I looked up at the sky. A single white bird soared freely through the clear blue expanse,

gliding far off toward the horizon, unfettered and serene.
