Having ascertained the condition of Empress Houtu, the following matters became clear and evident.
The Human Race has rich experience in rescuing Qi Cultivators who have fallen into demonic corruption; at this moment, it just so happens we can apply the right solution to the problem. Furthermore, a sliver of Houtu's true nature remains unextinguished, which greatly reduces the difficulty of the subsequent exorcism.
Li Ping'an and Qing Su returned to the surface and, after a brief discussion with the immortals, quickly established the exorcism plan.
The entire plan is divided into three main steps:
Stimulate the Demonic Qi, purify or absorb the Demonic Qi, and completely exorcise the demon.
Stimulating the Demonic Qi is simple; one only needs to make Houtu reveal her state as a major demon once again, to stimulate all the Demonic Qi.
But how to purify or absorb this massive amount of Demonic Qi has proven challenging for the immortals.
