Binhai City - a coastal city where prosperity and decadence coexist.
On the ground, the neon lights are bright and there are many tall buildings. Everything operates according to the rules of law and order. Underground, interests, violence, and favors are woven into another huge web. Gangs are divided, the weak and the strong eat each other, and the cruel laws of the jungle are followed.
Ten years ago, a couple mysteriously disappeared after revealing a shocking secret, leaving behind a minor son and a key engraved with a mysterious number. Ten years later, an email spanning time and space dragged the boy back into the whirlpool of fate.
His name is Lin Yue. He is the night shift network administrator of a shabby Internet cafe. He was about to become the redefiner of the city's underground order.
