All seven billion people on Earth are plunged into an endless survival train.
Cold, merciless rules descend. Once a day, the doors open onto a random and eerie alternate space. There are time-limited escapes, monsters lurking everywhere, and unpredictable natural disasters. Death is the end.
Lin Sensen, a twenty-three-year-old aspiring track-and-field athlete, is caught up in the apocalypse alongside her chubby cat, Zhuangzhuang.
Everyone gets only one special choice. But because she has an extra lifeform bound to her, she unlocks double privileges and double rewards. She has an incredible advantage from the start!
A deserted village steeped in silence, a life-devouring black mist that turns anything it touches to ash, savage hunting beasts formed from the fog...
Everywhere lies a seemingly inescapable death trap, yet every step offers a chance to survive against the odds.
The endless train has no final stop, the eerie spaces are always deadly, and natural disasters and monsters keep appearing.
Lin Sensen has always believed she can carve out a path to survival in the apocalypse, with Zhuangzhuang by her side.
