A strange disease suddenly occurred in Qingxi Village, surrounded by green mountains. The villagers had high fever and ulcers all over their bodies. The doctor from out of town was helpless and the village fell into panic. At this time, Shen Yan walked into the village carrying an old medicine box. He was dressed simply, but he could identify the disease at a glance and pick herbs. A few decoctions could make the seriously ill patients better.
The villagers gradually relied on this "living god", but they did not know that Shen Yan was once the head of the Imperial Hospital in the capital. He lived in seclusion in the countryside because he did not want to be involved in the palace medical battle. As the treatment progressed, he discovered that the strange disease was related to the polluted water source in the back mountain, and also involved the shady activities of the medicinal dealers. In the end, Shen Yan not only cured the villagers, but also revealed the truth and purified the water. From then on, he stayed in Qingxi Village and used his medical skills to protect the health of his neighbors.
