Li Yuanba had almost forgotten about the matter of the Purple Flame Sect's mountain gate, mainly because the 'Xirang' was still on his original self, Li Shiming's side. Due to his unfamiliarity with 'Xirang', Li Shiming hadn't discovered its use.
Such top-tier Heavenly Materials and Earthly Treasures typically wouldn't appear in jade scrolls, primarily because too few cultivators even know about them. Even those who do often regard them as mere legends and not real.
It's like Qi Refining Cultivators hearing about a phoenix. In their understanding, a phoenix is a Divine Beast, and they can't comprehend how high-level cultivators could tame a phoenix as a spiritual pet.
