Lin Xu, a low-level odd-job worker of the Azure Firmament Sect, awakens the supreme treasure, the All Heavens Heavenly Dao Memorial Tablet Book. By wiping the memorial tablets, he can connect with the ancestral masters of the upper realms across all heavens. Chu Tianba, the master of the Nine Heavens Sword Sect, invades wielding an incomplete ancestral sword technique, attempting to destroy Azure Firmament. Crisis arrives, and Lin Xu summons the ancestral masters for dimensional suppression. Afterward, his older brother Lin Xuan strikes with a black mist force, hiding behind it the huge conspiracy of the traitorous immortal Xuanyuan. The boy who wipes memorial tablets is thus drawn into the disputes of all heavens.
