National Train Survival: While Everyone Else Runs for Their Lives, I Crawl into Tunnels

While others struggle to survive the apocalypse, carefully rationing every drop of energy, Lu Fengxian’s train comes with “unlimited power.” While others see tunnels as meat grinders, he has “Tunnel Overlord,” which lets him reveal the entire map.

But he has his own troubles. This “people-first” System needs to upgrade the train, and it won’t take ore or cores. It only accepts the “bond level” (recruitment progress) of beautiful women with high ratings.
