Chan Yinsha rummaged through the two boxes and found two secret manuals: "Nine Yin Soul Thought" and "Six Yang Soul Gaze."
Both methods were visualization techniques, capable of enhancing one's mental realm.
However, these two visualization techniques were extremely insidious; in the process of visualization, it was akin to making offerings to an Evil God, sacrificing one's own soul to some supreme entity.
Over time, one's own will would be influenced, and subsequently, one's temperament would undergo great changes.
This, however, was something Chan Yinsha failed to notice.
After all, she didn't recognize these two individuals, but she could still draw reference from these two visualization techniques, learning by analogy.
Because she herself had a visualization method, which was to visualize the holy embryo's form belonging to Sun Shisheng.
