The tale tells of an arm severed by Hongjun Daozu since ancient times and sealed within Mount Shu. Utilizing the projections of the various heavens, it had nearly escaped—despite the Three Pure Ones' calculations, they were still a step too late.
Yuan Shi Immortal Monarch had long predicted the existence of the projections of the heavens, and this very arm was the key to drawing him out. Indeed, the assembly at Mount Shu held true to expectations, managing to detain the arm and almost resealing it, which in turn triggered the arrival of the heavenly projections.
Upon the appearance of this projection, it startled the Black Coffin resting within the Dragon Eye of Mount Shu, where a person quickly emerged, reaching the Three Pure Ones in an instant.
"It's you!" The cold eyes of the heavenly projection shone with an unusual light.
