Delivery boy Lin Feng's life was completely derailed late one night. When he stepped into the haunted house, his own shadow came to life and swallowed the resentful spirit. Since then, he has gained the ability to grow by swallowing ghost shadows, and the shadows have become his armor and blade, wandering through the increasingly frequent strange events in the city.
He once thought he was a hunter in the dark. However, the cold truth gradually swallowed him up: each swallow deepened the imprint called "coordinates" in his soul. He is not the savior, but the "door" that connects the abyss and leads to the end of the world. The stronger the power, the more stable the portal, and the faster the countdown to destruction.
There is a stubborn detective who pursues the truth, a greedy collector who sees him as a rare commodity, and an elegant fanatic who believes in destruction. Inside the body, the devil whispers day and night; outside the body, the fear and hostility of the world turn into the muzzle of a gun.
When the final choice came, Lin Feng stood on the edge of the abyss: Should Lin Feng end himself as a "human being" in exchange for the world's respite? Or embrace destiny as a "door"? Or, in an absolute desperate situation, this cursed fate and power can be forged into the last shadow blade that can tear apart gods and demons in reverse.
