The deserted road in the middle of the night, the boundary between yin and yang.
No one knows that there is a Yindu passenger car passing through the thick fog in the middle of the night. Anyone who is picked up by it is separated from the mortal world and becomes a prisoner of the ancient inn in Huangquan. The world calls them - innkeepers.
Shen Yan, an ordinary young man, accidentally fell into this Netherworld transfer station that had been sealed for thousands of years. The second-floor post gate opens month by month, and twelve sinister and sinister posts appear in the world. Every dungeon is a life-threatening situation. Every rule is tied to the lives of the living. Those who violate the rules will be driven to pieces.
In order to escape their unsolvable fate, all the innkeepers have to fight their way through the level and collect the twelve jade talismans scattered in the world before they can touch the forbidden ultimate truth. In a desperate situation, Shen Yan awakens his natural talent, the Night Eye, which allows him to see through false illusions, trace the origins of the evil past, and find a slim chance of survival in the cage of murderous rules.
The road to survival is never walked alone, and there is no path of pure kindness. The three parties of the post guard who insist on the balance of yin and yang, Duerlou who tries to subvert the order, and Zhenlingsi who wantonly domesticates creatures are fighting endlessly. Betrayal and sacrifice are intertwined, and fetters and fate are in conflict. Under the layers of copies, there is a plan to return to the ruins that has been hidden for thousands of years. The doomsday catastrophe of the underworld flowing back and the bones of the human world has been quietly brewing in the dark.
In the thousand-year cycle of reincarnation, all living beings are pawns, and those who enter the stack are destined to die.
But Shen Yan decided to go against the trend, break the iron law of the netherworld with his mortal body, and break the closed loop of fate with his obsession.
The underworld locks all sentient beings, and I reverse the yin and yang!
