All Races Awaken, and I Use Humanity to Subdue the Heavens

An elite mercenary known around the world transmigrates into the body of a high school senior in the apocalypse. He intends to keep to himself, relying on his deadly skills, but is saved by the white-haired, red-eyed "last guardian of humanity," drenched in blood.

She says, "I am humanity's only hope."

But in her shattered armor and hollow eyes, I see a shocking secret: the so-called "Battlefield of Myriad Races" is nothing but an elaborate scam!

We humans are merely "gu" insects kept by some hidden mastermind!

And I have awakened the one and only Law of Causality, the power that can see through the truth.

So she won't have to fight alone anymore, for my fallen brothers, and to tear apart the lies of this world!

I will follow the threads of causality, untangle the clues, and expose the player pulling the strings behind the myriad races!

"In this life, I will carve out a path for humanity!" Not just for survival, but for truth and dignity!
