Many years ago, the martial arts world was in chaos. Four major families joined forces to calm down the martial arts world. They were the Shangguan family, the Han family, the Leng family, and the Gongsun family. The four major families maintained peace in the martial arts world respectively in the east, south, west and north corners. For many years, they did not invade the river. But one day, Shangguan Jiannan and Han Motian accidentally discovered an unknown secret, which led to their deaths. The family was exterminated by the Leng family and the Gongsun family. Their children, Shangguan Lingyun, escaped death because they went out to study under their masters. Han Ruoyi also escaped under the desperate protection of her father. From then on, the two strangers began their own wandering journeys. In an accident, the two met, but were inexplicably hunted by two major families. From then on, they staged scenes of touching stories with their friends.
