The abyss has never really closed, and the game between light and darkness has just changed to a different battlefield.
In the ending of the first part, the protagonist Chu He uncovered a corner of the conspiracy in the whirlpool of black and white, but also entered a more dangerous forbidden area. Two years later, the seemingly peaceful city was in trouble again - a transnational smuggling case led to the "Darknet Parliament" in the underground world. Behind the Parliament, there was actually a "bloody key" closely connected with the death of Chu He's late father.
In order to pursue the truth, Chuhe was forced to join forces with his former enemies to form a "shadow team" in the gray area that wandered on the edge of the law. They sneak into the dark alley where neon and blood coexist, and deal with the chess game of power and desire, but gradually discover that the so-called "black and white" are just lies controlled by a higher dimension. When the boundaries between loyalty and betrayal begin to blur, the only thing that is clear is the ultimate secret hidden in the key - it can reshape the order of the city and completely devour everyone's soul.
Behind the key, is there the dawn of redemption or the beginning of complete depravity? When the distinction between black and white is no longer clear, who can still hold the last restricted area?
Concept: The abyss never really closes, and the game between light and darkness just changes to a different battlefield.
