The Emperor of Water and the Emperor of Fire competed for the world, but the Saint of the Water Empire, Sheng Zan, and the Prince of the Lava Empire, Long Ruan, fell in love beyond their hatred and gave birth to a forbidden son, Chen Hao. Chen Hao was frozen in the light pole, but was later rescued by the disciples of the witch formation. He gradually grew from an aphasic boy to a practitioner of the "Nine Transformations Mysterious Art", "Heavenly Demon Art" and "Fire Fire Art". In order to cure the cold poison, find his life experience, and avenge his parents, he and the little demon Hua Yichu, the wind tribe boy Yan Fenglie, the moon god Laitifa and others traveled through the Hopeless Sea, the underworld and the God and Demon Pavilion, and faced the Water Emperor and the Asura tribe. Love, sacrifice and revenge are intertwined. The so-called hopelessness is just the sea leading to rebirth.
