Retired Chinese medicine practitioner Li Mu unexpectedly awakened to his ancestral heritage when he was terminally ill. He not only cured stubborn illnesses and reshaped his body, but also acquired magical powers such as medical skills, martial arts, hexagrams, and Feng Shui. He found out the truth about his son's murder, endured the conspiracy and punished the evildoers, rescued people in danger and made friends with others on the way, relied on his skills to cure diseases, and accumulated connections. While searching for his daughter who had been missing for many years, he prepared a clinic to help the world and save people, and started a counterattack in his later years.
