The Boundless Ghost Realm

The Boundless Ghost Domain is a separate dimension beyond the real world. No one knows where it came from or why it exists. The only certainty is this: once you're chosen, there's no going back.

It contains endless eerie instances, with an unknown world of terror behind every door. Abandoned schools, hospitals where the dead lie in wait, towns trapped in eternal night, sunken cruise ships... Rules twist, monsters roam, and the slightest mistake could leave you trapped forever.

Some choose to cooperate and band together for warmth. Some choose to plunder, where the strong prey on the weak. Some seem friendly on the surface, but are waiting to give you a shove at the crucial moment.

Ghosts aren't scary. The human heart is.

Two men struggle to survive through one instance after another, constantly teetering on the brink between life and death. Liu Jianhao uses the meticulous logic unique to a math teacher to solve puzzles, while Chen Guanbo uses the insight he honed in the bureaucracy to see through people's hearts. They go from awkward strangers exchanging polite pleasantries to recognizing each other in the dark by the sound of their breathing.

What is trust? It's daring to turn your back on someone in a world that tells you, "Don't trust anyone."
