The art of medicine can cure every affliction.
The finest physician treats the nation? No, a physician can treat anything.
The protagonist, Chen Xuanming, used to be a doctor at the Traditional Chinese Medicine Hospital in Tianyang City. He was just an ordinary wage earner, living a fairly uneventful life. But the hospital had been built with shoddy construction. While trying to save a child, he was struck and killed by a falling window. He had no idea who was behind it. When he opened his eyes, he had transmigrated back to the age of chaos, just after the Great Dao had opened it. The three thousand Demon Gods were still gestating, and he happened to take the place of the Demon God of Medicine, also known as the Demon God of Life. He was born bearing the Great Dao of Life.
