Since the "True Scripture" was clearly written, Li Pan naturally would not aim too high and go flipping through some "Heavenly Book." Instead, he earnestly followed the overall guidelines in the manual, step by step, and thoroughly studied the "Nine Yin Divine Skill."
Although there were a few characters he did not recognize and sentences he could not understand, with the foundation set by "Shape Refining," Li Pan managed to comprehend it. This "Skill" was indeed for martial arts practice, resembling a type of advanced internal boxing technique. It was designed to work in conjunction with "Shape Refining" to cultivate Nine Yin True Qi, strengthen muscles and bones, toughen the skin—a gaming term would be to increase attack power, defense, and vitality.
