The blood-soaked "Corridor of the Abyss" is a purgatory that devours the living and a gamble that binds fate. Those who are forced to be involved in infinite trials can only open the door of desire and gain a glimmer of hope by surviving to the end in each of the strange dungeons.
Xie Jin, a former special tactics instructor with a fighting spirit, stepped into desperate situations to resurrect his comrades who died. He has ruthless skills and excellent tactics. Military daggers are his fangs. His instincts honed in the hail of bullets allow him to tear his way through the roars of resentful spirits and strangulation by rules.
Shen Nuo, a genius forensic doctor, has a soft and sweet baby face, but his eyes are icy. She entered the game to find her missing sister, and the autopsy forceps were her weapons. From the texture of the corpse and the clues in the environment, she accurately dismantled the survival rules of the copy, and she was so calm that it was almost cold.
On the rooftop of the novice copy, the two faced each other due to the only "hourglass of time", but under the desperate situation of being surrounded by resentful spirits, they were forced to form a temporary alliance.
In a Chinese-style treacherous building, a paper man clings to the door and demands his life; in a Western castle, a vampire's fangs pierce the long night; deep in the mirror maze, the evil god whispers to confuse people's hearts... They have overcome layers of bloodshed and transformed from rivals who were wary of each other into comrades who surrendered their lives back to back.
When the truth of the trial emerged, they were shocked to realize that the so-called door of desire was just a bait for the evil god to raise sacrifices. The chosen one is never a player in the gambling game, but a lamb to be slaughtered.
In a desperate situation, two strong men stand side by side. Will he become the nourishment of the trial, or will he overturn this false rule and find a way out?
