In 2049 AD, a red meteor shower swept across the world, bringing unknown viruses and cracks in other dimensions. The once glorious civilization collapsed within seventy-two hours. When the last fortress of mankind fell, the legendary mechanic "Mo Wu" detonated the core energy and died with the king-level beasts, but he was reborn three days before the end of the world - becoming Lin Mo, a 23-year-old mechanical engineering graduate student who was abandoned by his family. The left hand is the unforgettable memory of the past life, and the right hand is the blueprint of the "Genesis" mechanical core that is still under development. In this life, he is no longer loyal to anyone. Build a shelter, subdue the strong men from the past, unlock black technology, and fight against mutants and careerists. While others are still struggling for food, his base has set up a fusion reactor; while various forces are fighting for control of the ruins, his mechanical army is cleaning up the entire city. However, as the apocalypse deepens, Lin Mo discovers that behind this disaster, there are surprising secrets across dimensions - and his rebirth seems to be no accident.
