The core of Returning Flame Soil is to burn plant Yuan Qi, transforming it into flames to attack enemies, and then the ashes of the flames nurture the plants in reverse, using battle to nurture the body, strengthening the body for further battles. This is An Jing's experimental cultivation targeting the "Yuan Qi and flesh".
Pupil Fire is used to ignite Spiritual Fiend, Jade Marrow Bone withstands the sudden burst of Yuan Qi, and Circulatory Organs transmit the exploding Yuan Qi. Strength from Thought is the best Divine Abnormality for controlling Yuan Qi, this principle is similar to the turbocharger engine An Jing had in a past life. So the fifth Divine Abnormality is undoubtedly to increase Yuan Qi combustion efficiency, while the sea in Bright Flame Sea refers to the Dantian Qi Sea, a Divine Abnormality similar to "Dantian Sea" but enhances the boosting capacity of the Dantian Sea.
