An urban counterattack story full of satisfying thrills set in an end-times adventure and escape. In his past life, Zhang Jingcheng was framed by his superior Jiang Yan and betrayed by his fiancée Tian Wenjuan, then ruthlessly pushed into a horde of mechanical rats and died a cruel death. Reborn thirty days before the end times descend, he awakens a top-tier space-type Fire Seed. From the start he builds a heavy mecha, frantically stockpiles supplies to create an impregnable shelter, exposes the scoundrels and the unfaithful woman to their faces, and defeats the hypocritical do-gooders, growing stronger step by step in an end-times overrun with cybernetic monsters.
