Trapped in a Sinister Prison, Escape Is Just the Beginning

[Infinite-loop survival + escape + no System + mild horror]

A stranger bumped into him on the subway, and just like that, he was gone. When he opened his eyes again, eight people were imprisoned in an underground iron cage.

Crossing the line only triggers a warning. Trying to escape brings a deadly pursuit, and the more desperately you run, the more frenzied the attacks become.

While everyone else curls up and waits to die, Ouyang Xun relies on the mechanical repair skills he picked up as a young apprentice. He twists screws, picks locks, and dismantles pipes, slowly figuring out the rules of this place and searching for the one way out.

Some people risk everything to run, only to be put back in their beds, their fate unknown.

Only after he pries open a pipe and truly escapes does he understand: this prison is nothing more than the first train departing from a strange platform.
