In the Ninth New Capital, which is soaked by acid rain and neon lights, the upper class live in the "sky dome area" above the clouds, while "scavengers" like Gu Chuan forage in the cracks of the dirty and chaotic "sinking area."
His only dream is to save enough credit points to replace his prosthetic eye that occasionally freezes, and to take care of his old robotic arm.
A mysterious commission from the "Sky Dome Zone" dragged him into a bottomless whirlpool. An abandoned biological research institute, wildly proliferating alien flesh, and a secret that was deliberately buried.
When the boundaries between cold machinery and warm flesh blurred, and when the whispers of monsters echoed in his mind, Gu Chuan discovered that the "garbage" he wanted to clean up was far more than just the ruins of the city, but also the madness and lies rooted in the deepest parts of the world.
And he himself is becoming something... New and undefinable.
