Wu Sen's parents were brutally murdered.

The prisoner, Lin Xuan, was arrested and brought to trial, but he produced a doctor's certificate stating that he was mentally ill.

In court, Wu Sen was caught in an emotional black hole. In a fit of rage, he rushed over and tried to strangle Lin Xuan, but was pulled away by the police and kicked by Lin Xuan. His head hit the corner of the railing, and he fell into a coma.

When he awoke again, the world was quiet, and unknown sounds rang out, like the roars of wild beasts.

Man-eating zombies, monsters and alien species that humans cannot fight against.

The end of the world is coming.
