My Doomsday Train Novel

In a post-apocalyptic wasteland overrun by zombies, humanity's survivors must become Train Captains to stay alive. They scavenge ore and minerals to construct and upgrade armored trains—their sole protection against the undead hordes. Those who fail become slaves to other Captains. Every train component has a maximum upgrade level, but Chen Mang possesses a mysterious birthmark that shatters this limitation. Unlike other Captains who ignore low-tier parts such as Carriage Blades and Drill Rams, Chen Mang enhances these common components to unprecedented heights. His limitless upgrade ability soon makes him unstoppable. Commanding a colossal, heavily armored train stretching hundreds of carriages long, Chen Mang carves a devastating path through the apocalyptic wasteland. In this brutal new world, only two roles exist: Train Captains who rule the rails, and slaves who serve them.
