In Moshi Village deep in the Yanshan Mountains, young Lin Mo was called a "fool" by his neighbors because of his pure mind and ignorance of the world. However, he inherited his grandfather's ancestral medical classics and a rare superpower-the ability to see through human lesions. He travels deep into the mountains every day to collect medicines, uses "silly tricks" to treat illnesses and save people, uses wild springs to boil medicines, and uses silver needles to detoxify. Although he is ridiculed by villagers and questioned by local doctors, he always adheres to the ancestral motto of "treating diseases without charging a penny."
During a strange encounter in the mountains, Lin Mo was enlightened by a mysterious black stone. His powers were completely awakened, and his medical skills became increasingly sophisticated. He cut and drained pus to save the man, used acupuncture to dispel cold and treat the lady, and used herbal medicine to treat rheumatoid arthritis. All difficult and complicated diseases were solved in his hands. Li Cui'er, a simple and honest village girl, never left his side and accompanied him by sending him food. Su Qingyao, the daughter of a wealthy man who had taken refuge in the mountains, was purely moved by him and stayed in Yaolu to help him.
From the emergency rescue at the grain drying farm at the head of the village to the busy day and night in the medicine house, Lin Mo solved doubts with his kindness and won respect with his medical skills. The name of the "Idiot Miracle Doctor" spread throughout the countryside, attracting patients from all over. Amidst the fragrance of vegetation and the fireworks of the world, he fights against secular prejudice with his pure heart, uses ancestral medical skills to continue writing the legend of a doctor, and in the company of two women, he quietly develops a warm and touching relationship.
