It is evident that the Silver Chrysosplenium Stamen Cassia did not evolve along the existing bloodline of Bright Moon Golden Osmanthus!
Such a situation had appeared before during Fang Mu's use of the Fool's Shadow, Eye of Omniscience, an innate divine ability.
For example, the evolution of the Dark Nightmare Tiger into a Subduing Dragon Nightmare Tiger is a mutation superior to its own bloodline, requiring resources as precious as a complete Dragon Ball.
The spiritual material required for Bright Moon Golden Osmanthus to evolve into Silver Chrysosplenium Stamen Cassia is equally, if not more, precious and rare, potentially more so than a complete Dragon Ball.
It needs to absorb high-purity life energy daily. The higher the purity of the life energy it absorbs, the higher the probability of its evolution into Silver Chrysosplenium Stamen Cassia.
