Two hundred years ago, Luo Yuqing, who had the appearance of a celestial being, entered the troubled times with the twenty-one shadows of the Demon Sect. He befriended Sikong Xiangnan, and together they conquered the world, quelled the chaos and founded the country. Two hundred years later, Yan Wu, the leader of the sect, was born intelligent but not in good physical condition for martial arts. During his seventeen years in office, he raised the next monarch Cheng Sijin, but she was a woman as bright as the bright moon. She entered the world to seek medicine for her master, and met Gu Muqing, a disciple of the holy doctor. Their love was deep, and the demon sect monarch could not have an heir. Territory Gu Island was destroyed, resulting in heavy casualties, and Sijing was pregnant at this time. Fengchen Jibian, who had been wiped out by Yan Wu, took the opportunity to spread rumors in the rivers and lakes that the Demon Sect kidnapped the holy doctor and destroyed Yunshan, causing the martial arts warriors to gather together. Afterwards, the Demon Sect was regarded as a public enemy by the martial arts. Eleven years later, Feng Chenjibian used the chess pieces of the Demon Sect to kill Shaojun Sijin with seventy-two poisons. Gu Muqing died in love. The young masters Gu Niancheng and Haitang Qingchen fell into the underground sea, and entered the world with a blood feud on their backs. They met Liuhuo, who was abandoned by his relatives. They had different fates but were in the same situation. Gu Niancheng didn't know what love was, but after the bloody storm, he only wanted Liuhuo by his side.
