In 2059, the Third World War entered its fifth year. Seventy percent of the earth's surface was reduced to nuclear-contaminated ruins. Evolutionary factors gave rise to awakened beings and mutated creatures. Giant mecha factions were divided. Humanity was struggling to survive in steel settlements.
Ye Hao, a survivor of Rusty Street, awakens to the "reincarnation system" when he is dying and falls into a ten-day cycle - he is forced to die on the tenth day. After rebirth, he retains all memories, powers and mecha skills, but loses some of his emotions. He made trial and error after death: unlocking steel perception to predict the movement of mechas, awakening thermal energy to control fuse armor, and transforming from a survivor into a warrior controlling the ultimate mecha.
Key ally Lin Xia's mechanical watch hides the coordinates of the source of the evolutionary factor, but he always dies in an assassination on the 5th day; the federal army's nuclear bomb cleaning plan, the rebels' superhuman mecha ambitions, and the out-of-control AI "Skynet" (a distortion of the peace agreement)'s annihilation conspiracy, weave a deadly web. Ye Hao must break Lin Xia's death fate before all his emotions are lost, unite all people of conscience, fight against the three major factions, and end the cycle in the 21st reincarnation.
When the core origin of the evolutionary factor and the tragic logic of Skynet are revealed one by one, he will finally understand: reincarnation is not about immortality, but to burn out war and greed in the ashes, so that civilization can restart in the ashes.
——Ten days of life and death, the end of reincarnation, ashes or new life
