Essentially, it is based on the Heaven and Earth Core, gathering myriad Spiritual Fiends into Dragon Qi, using it as the core to regulate the Inner Array Realm, fusing power and Soul and Spirit into one Pill, forming Martial Dao Ice, laying the groundwork for future transformation into Cave Heaven.
In this process, the Heaven and Earth Core extracts the Spiritual Fiend of all things in the world and transforms it into the process of the Ten Thousand Spirits Pill, which also provides Dragon Qi to supply You Ruhui's cultivation, enabling her cultivation speed not to be inferior to the best Emperor's Blood of the Great Chen Imperial Court.
An Jing helped in constructing the Heaven and Earth Seed, contributing a lot of his own cultivation experience in True Spirit Blood and Dao Becoming Flesh.
