The blind Li Ping'an, relying on erhu mastery to learn extraordinary skills, travels through the troubled jianghu accompanied by a spiritual ox. Moved by the kindness of ordinary people to help others, he travels through many cities, meets various characters, and gets involved in multiple disputes. After bitter battles, although given the chance to repair his limbs, his eye disease has still not healed. Taking court disturbances lightly, he chooses to continue wandering the jianghu, guarding his original intention between the marketplace and flashing swords.
