The day Jiang Ran rescued his life from the rubble, he lost his left arm and right eye.
The military said he was "no longer fit for service" and gave him a thin discharge certificate and a pension that was not enough to buy a prosthetic leg.
Four years later, in the underground arena of the Seventh Fort Wasteland, Jiang Ran used one hand and three tons of scrap metal to build a combat machine capable of taking on military mechas.
Everyone calls him the "Wizard of the Wasteland" and everyone wants to buy his life.
He's not interested.
Until the girl covered in blood fell out of the shadow of the fortress and thrust a data chip stained with brains into his hand.
The chip contains the last image of his father before he disappeared:
"Xiao Ran, the end of mankind is not that alien creatures break through the fortress, but that they give up on being human. I built a mecha for you - it doesn't need a perfect soldier, it needs an imperfect soul."
Three days later, the coalition government declared the Seventh Fort to be on "highest alert" and all exits were blocked.
Jiang Ran looked at the people in the city who were beginning to mutate, and finally understood the meaning of his father's words.
The end of the world does not need a hero, it needs a madman who can smash the gods with a wrench.
This is a steel lullaby dedicated to the wasteland.
When everyone was running for their lives, he chose to build a mecha that could kill "gods".
