In his heart, he carefully weighed his options. The Soul Nurturing Technique is a spell that nurtures a second divine soul, similar to a doppelganger. Even if there are some differences, they wouldn't be significant, which wouldn't be very helpful to him since he already had a second doppelganger, Fang Yan. As for the Secret Technique, Spirit of the Earth, which extends lifespan, it was also somewhat unnecessary to him. After all, he believed that once he reached a certain realm, his lifespan would naturally increase. Truly cultivating to a certain level, lifespan wouldn't be an issue!
Therefore, among these three Secret Techniques, he was most inclined towards the Soul Imprint. Although he didn't know what the Soul Imprint could do, he knew it was definitely extraordinary. After some deliberation, he finally spoke to the Ancient Stone Spirit in his heart, "I've made my choice, the Soul Imprint."
