Lu Chenyuan, a deliveryman publicly branded a coward, receives a top-secret military decree, and the entire city kneels to welcome him. The blood of his old comrades has yet to dry; the lies of his former lover have yet to be exposed. Su Zhaoyue hands him a blood-red chip amid a power struggle, Qin Ya silently passes him a shattered military ID in the rain, and Zhao Tiehou's neural arm goes berserk for the first time... When the "Tianshu Military Spirit" awakens, he learns that he hasn't returned as a hero. He's the final Host of a military experiment. And the ones who truly deserve to kneel are the "people" sitting high upon their altars.
