第九纪元之回溯列车

In a future world, a meteor impact triggers a mass extinction, forcing humanity to migrate underground for survival. To secure more resources, Lu Feng, an ordinary dweller of the underground city, joins a bounty hunter team led by Di on a mission to the surface. During their exploration, they accidentally stumble into the ruins of an ancient civilization known as "Fuli." After enduring numerous life-and-death crises and solving intricate puzzles, Lu Feng boards the Fuli Train, experiencing endless cycles and traversing through epochs of time. He battles formidable alien beasts and even confronts another version of himself, gradually uncovering the "secret of immortality" and the ultimate truth of the world. Ultimately, he saves the world and ushers in the legendary "Ninth Epoch."
