The Dao Venerable of Nonaction and the Demon God of the Dao-less have been locked in conflict since the birth of chaos. The turn of each era reflects their struggle over the Dao, and the victor determines the order of the next era.
In the modern cultivation world, Yang Xuan, a village youth, accidentally obtains the "Taixu Seal," which contains the legacy of the Dao Venerable, and embarks on the path of cultivation, becoming a crucial pawn in the fight against the Demon God.
As Yang Xuan grows stronger, he gradually uncovers the truth hidden behind the cultivation world: the Demon God's power is seeping into every sect, brewing a dark upheaval that will overturn everything.
As his cultivation advances, Yang Xuan discovers a deeper connection between himself, the Dao Venerable, and the Demon God. In the end, he must confront the truth that he is the reincarnation of the Dao Venerable's final divided soul.
