In order to explore the mystery of his life experience and the death of his parents, Jiang Hao, a demon king from another world, concealed his half-immortal cultivation and hid in the lower world as the son-in-law of the Feng family. He faced ridicule on the surface, but secretly resolved Wan Zhiming's difficulties with a snap of his fingers, attracting the attention of the Immortal Alliance, and even attracted the pursuit of evil sects from other worlds. When Feng Yiyun was kidnapped by the evil sect, Jiang Hao turned his hand to destroy the powerful enemy and quietly changed everyone's perception. The clues revealed by his father-in-law revealed that his father's death was not an accident, so Jiang Hao took the name of his adopted son-in-law as a sheath. In the undercurrent and cross-border pursuit in the five realms, he gradually uncovered a shocking conspiracy, walked in blood, and pointed to the road of supreme revenge.
