Isekaid 40ish Man Returns, Regressed as a Peerless 17-Year-Old

The monster, though humanoid, had the body shape of a cyclops with muscles all over its body.

The most distinctive of all was its…..

「You made this thing.」

『What do you mean?』

The chief’s voice comes out from a speaker installed somewhere.

He’s probably watching us with a camera.

「You have synthesized variants to make this thing. Roughly a hundred of them….and you used humans to control it.」

『Hou……how brilliant of you to know that in a glance. However, whether you can beat this synthetic oni is another matter.』

The most distinctive feature of this monster is the human head, which is supposed to be its weak point. It is constantly moving inside its body.

I wonder if there is a variant who is good at this kind of technique.

There was a demon that synthesized all the humans of a certain country and turned them into a massive giant of flesh. This is similar to that.

-0-

Even though there are only a hundred of them, they still synthesized lesser onis.

In terms of magic power, they surpass humans in general.

「Guoooooooooo……」

The synthetic oni grew horn on its forehead and concentrated its magic power there.

The horn alone is about the height of an adult male.

It charges fast too!

「Gaaaaa!!」

At the same time as the synthetic oni howled, a beam of magic power cannon with a diameter of around 3 meters was shot toward me.

For now….evade it!

I ran past the cannon and cut off the synthetic oni’s head.

However, the synthetic oni didn’t care a bit about that and swung its thick arm.

That’s it!

I kicked its arm and moved away.

-0-

As I landed, the magic cannon was about to hit me!

What the heck!

The wall behind me reflected it!

While catching the magic canon with my palm, I analyzed the magic on the wall.

In addition to increasing hardness, there is also a reflective magic spell applied on it.

So this thing, combined with the synthetic oni, is their trick to repel intruders.

This base is probably the pinnacle of technology related to variants.

The synthetic oni, whose head had already regenerated, extended its arm to the cut off head on the floor and absorbed it.

As expected. Given how it was made, there’s no point in dividing it apart.

-0-

The synthetic oni concentrated its magic power in its fist and swung it at me.

I easily avoided it but the magic power that reflected on the floor hit and blasted me up to the ceiling.

A force geyser!

But awakening is going to be out after being hit by three times.

While I was thinking of unnecessary things, I was shredding the arm of the synthetic oni.

However, the pieces of flesh that I had cut off into dice sized pieces attracted each other and were absorbed by the main body.

Then!

I held my black sword in my right hand and light sword created by magic in my left.

「Guooooooo!」

Then, the synthetic oni charged at me.

This time, both of its hands are filled with magic power.

First, the right hand!

I evaded it while cutting off its right arm and then did the same thing with its left.

As if that was a decoy, the synthetic oni released a magic cannon from the horn on its head.

-0-

I caught it with my two crossed swords and sliced the synthetic oni’s body open along with the magic cannon.

The human head inside the synthetic oni’s body was also cut in half.

It is at the weakest part of the swirling magic power. It is easy to see that it’s the weak point.

-0-

The synthetic oni fell to the ground with a “thud”.

However, it began to regenerate again.

The human head inside its body also began to regenerate.

Even the brain has been eroded by the variant and has ceased to be human?

『Outstanding skill. I can’t believe you are a human……however, what do you think? As long as it has magic power, it will regenerate over and over again!』

I’m sorry for the ‘certain victory chief” but I can think of more ways to defeat it than I can count on the fingers of my two hands.

Combat is my specialty.

I’ve made up my mind, let’s use that.
