The starship Tianyuan was destroyed by a wave of insects over New Tokyo. The SSS-class soldier Lu Zheng fell into the ruins and became the last fire. He met researcher Su Wanqing and discovered that behind the insect tide was hidden the gene trading of high-level municipal officials. Underground leader Huo Gang, special service captain Chu Lingxiao, AI engineer Eve Li, street boy Zhou Ye, all forces gathered in the broken city. Lu Zheng tore apart the insect swarm with his bare hands, but fell into a bigger conspiracy - the brood was awakening, and the truth was buried in his out-of-control memory. In a deadly battle that ignites the whole city, who can survive the insect wave until dawn?
