Lin Tianchen stepped into the secret manual area with high expectations, his gaze eagerly sweeping across rows of bookshelves. Suddenly, a faint yet mysterious glow caught his eye. Approaching it, he saw an ancient book weathered by time, lying quietly as if waiting for someone destined to open it.
Lin Tianchen cautiously picked up the ancient tome titled *Daoist Canon of Divine Treasuries*, gently brushing a thin layer of dust from the cover. As he slowly opened the pages, a stale scent washed over him, and at the same time, lines of text emitting a strange radiance gradually appeared before his eyes.
The opening page read: "Within the human body lie numerous divine treasuries, their mysteries as profound and boundless as the universe. Among them, the five viscera correspond closely to the five elements of heaven and earth. The liver belongs to wood, the heart to fire, the spleen to earth, the lungs to metal, and the kidneys to water. They generate and restrain one another in an endless cycle. By practicing this Daoist Canon of Divine Treasuries, one can gradually strengthen these deeply hidden divine treasuries within the body, causing them to radiate infinite potential."
