Reapers invade the Blue Planet, civilization collapses, and mechanical beasts run rampant across the wasteland. Fang Yuan, a resonator suffering from a fatal genetic illness, acquires the prehistoric Pangu battle armor in a crashed starship. Relying on his decoding and cracking abilities, he shuttles through the wasteland, battles the reapers, and searches for his missing father. The armor can devour enemy cores to evolve continuously, holding the possibility of curing his terminal illness. The Shadow Society and the city defense forces play a game against each other, with multiple factions lurking. Trapped in the apocalyptic desperate situation, Fang Yuan wears the armor and arduously explores the shattered world.
