Chen Mo is an ordinary office worker who clocks in every day and lives a life as dull as still water.
The supernatural descends. Yin energy shrouds the city, the living fall unconscious, and the human world becomes a half-transparent realm of ghosts.
A handful of people awaken spiritual perception and become Spiritwalkers, struggling to survive as they fight wandering corpses.
By chance, he obtains a sign-in System. One sign-in a day activates one of the seven marriage contracts within him.
Seven wives appear from his dreams, each a ruler of the underworld who commands the powers of the death realm.
Each time he signs in, they grow stronger, and he receives a hundredfold return, sending his power soaring.
While others battle desperately to stay alive, he shatters corpses with a casual strike and sweeps through the supernatural horrors.
Once an overworked wage slave, he now walks between the realms of yin and yang, and no one dares stand in his way.
When the throne of the underworld trembles, he shatters the void and is destined to ascend to the invincible peak.
