A century after the uncanny descended upon the world, humanity survives by making parasitic pacts with uncanny entities. Chen Mang, the last heir of the Vajra Sect, carries a blood feud over the destruction of his sect and the disappearance of his family. With the iron-body techniques he has practiced for nineteen years, he uses his pure yang vitality to break the deadly rules of countless uncanny domains, punching evil spirits to death and stamping out conspiracies. From a fallen martial artist guarding a small school, he grows step by step into humanity's guardian. At last, with his immaculate Vajra body, he shatters the invasion gate to the higher-dimensional uncanny realm and wins humanity a path to survival, one where the living need not bow to ghosts and gods.
