After losing his memory, Lin Feng became the Su family's son-in-law. For three years, he endured the humiliation and was regarded as a useless "trash". Only his wife and sister Su Yutong treated him sincerely. In an accident, he awakened his memory of medicine and martial arts. Acupuncture can bring him back to life, and his Xuanyang energy can defeat thousands of enemies.
In order to practice his benevolence, Lin Feng prepared the "Ren Xintang" Chinese medicine clinic, but he encountered repeated obstacles: the black fox, the remnant of Qinshan River, was provoking a provocation to seize the Nighthawk Order, the director of traditional Chinese medicine Zhou Ming came to provoke and question, and the drug dealer Wang Kun monopolized the price of medicinal materials, and even hired a killer "Ghost Shadow" to kidnap his family and force him to compromise.
Lin Feng used extraordinary medical skills to cure difficult and complicated diseases, and used thunderous means to thwart serial conspiracies - capturing the black fox alive, shocking Zhou Ming, smashing Wang Kun's monopoly conspiracy, and protecting his family in the crisis. His wife Su Qingyue went from initial contempt to complete love, and the family worked together to support the Chinese medicine clinic.
After the opening of Renxintang, Lin Feng saved people with medicine and protected the Tao with martial arts, letting the light of traditional Chinese medicine shine in Yaozhou. In the process of protecting his family and promoting the concept of "benevolent heart to help the world", he also gradually uncovered the mystery of past memories and wrote a legend of a hidden dragon coming out of the abyss to guard the city.
