Under the glamor of the city, there is a rotten viscera called the Gray Domain - the nest of exiles, supernatural beings and the black market, the ultimate jungle where the weak and the strong prey on each other.
Lin Mo, the "scavenger" born in the Gray Realm, cleans up the dirtiest blood and the remains of superpowers in the city. He himself is the epitome of the gray realm.
He is the gray area, and the gray area is him. Survival is an eternal war!
