According to Mo Renyi, he was originally a mortal doctor from a family of physicians. Because his father had lived next door to an old loose cultivator for many years and had formed a close relationship with him, he was helped by the old cultivator to embark on the path of cultivation.
However, after mixing around in the cultivation world for more than twenty years, Mo Renyi grew tired of the life of a loose cultivator and simply gave up on cultivating and returned to the mortal world. He took over the family's medical clinic, specializing in treating people's ailments and dispensing medicine.
