"Human Prison" is an extreme survival epic set after the complete collapse of order. When zombie viruses engulf the world like a tide, the only shelter is the last cage built by humans for themselves - a steel prison hanging alone in a sea of corpses.
Here, law and morality become the first wreckage to be gnawed away. Former special forces sniper Lu Chen, a prisoner serving a life sentence, is forced to establish a bloody balance between criminals and guards. What he has to fight against is not only the endless roaring corpses outside the wall, but also the betrayal and madness that may break out at any time inside the wall. And when zombies begin to "knock on the door" with their remaining instincts, and when unknown drones hover like vultures above the rain curtain, a deeper question emerges: Is this disaster a natural disaster, or a "screening" controlled by some cold will?
It is a desperate experiment in re-establishing order on the ruins of humanity. Trust is scarcer than ammunition, and the living are sometimes more dangerous than the dead. Lu Chen must lead this ragtag group of people to walk a tightrope between survival and redemption, while uncovering two truths that can overturn everything: Is this prison a shelter or a carefully designed cage? And is he himself a leader in survival, or is he a pawn in a huge script whose fate has already been marked?
Within the iron gate, survival is the only rule; outside the iron gate, a carefully buried world is slowly waking up. When the last barrier collapses, people will discover that the most terrifying monster may have never been locked outside the wall.
