Gu Xuanchen once stood at the pinnacle of the cultivation world, reigning as an unrivaled emperor whose power shook heaven and earth. During his glorious era, he personally trained ten disciples who each reached the Emperor Realm, becoming legendary figures capable of dominating entire generations.

However, while attempting to break through the final shackles restraining his power, disaster struck.

A devastating heavenly tribulation descended upon him, and despite his immense strength, Gu Xuanchen was ultimately destroyed by the overwhelming force of the thunder calamity. The world believed the mighty emperor had vanished forever.

Yet fate had other plans.

Reborn in a new body as a seemingly insignificant live-in son-in-law, Gu Xuanchen finds himself starting over from the very bottom. Armed with the memories and experience of his former life, he begins rebuilding his strength while concealing his true identity from the world.

As he embarks on his second journey, Gu Xuanchen slays demons, eradicates evil spirits, protects his family, and searches for the disciples who once followed him. Along the way, he uncovers hidden conspiracies and confronts powerful enemies that threaten both his loved ones and the balance of the world itself.

From a forgotten son-in-law to a legendary emperor reborn, Gu Xuanchen is determined to reclaim his former glory, surpass his previous limits, and once again stand at the summit of all creation.
