In 2059, the Third World War enters its fifth year. Seventy percent of the Earth's surface has become nuclear wasteland. Evolutionary factors have spawned the Awakened and mutated creatures, giant mecha factions carve up the world, and humanity struggles to survive in settlements of steel.
When Ye Hao, a survivor of Rusty Iron Street, is on the verge of death, he awakens the Reincarnation System and is trapped in a ten-day loop. He is forced to die on the tenth day each time, then reborn with all his memories, abilities, and mecha skills intact, but with some of his emotions gone. He learns through repeated deaths: unlocking steel perception to predict mecha movements, awakening heat manipulation to melt armor, and transforming from a survivor into a warrior who commands the ultimate mecha.
The wristwatch of his key ally, Lin Xia, hides the coordinates of the source of the evolutionary factors, yet she always dies in an assassination on the fifth day. The Federation Army's plan for a nuclear purge, the rebels' ambition to build superhuman mecha, and the world-ending conspiracy of the rogue AI Skynet, twisted from a peace treaty, form a deadly web. Before his emotions are completely drained, Ye Hao must break Lin Xia's fated death, unite everyone who still has a conscience, and fight the three factions to end the cycle on his twenty-first loop.
As the core source of the evolutionary factors and the tragic logic behind Skynet are revealed one by one, he will finally understand: the purpose of the cycle is not to live forever, but to burn away war and greed amid the ashes, and let civilization begin anew among the embers.
Ten days to life or death. At the end of the cycle, will there be ashes or rebirth?
