Gu Changyuan was once the most dazzling genius of the Tianxuan Immortal Sect. In order to pursue ruthless swordsmanship, he neglected his Taoist companion Su Nianwei for a hundred years. When he finally came out of seclusion, he found that Su Nianwei had rebelled against the Demonic Way and became the Empress of the Demonic Way. She was in charge of the Demonic Realm and wanted to subvert the order of the Immortal Sect. Gu Changyuan was ordered to track down the strange movements of the devil, but step by step he uncovered the truth behind the neglect - master Zhou Xuanqing's plan, Liu Ruyan's informant, and the bloodline of the devil emperor sleeping in Su Nianwei's body. Under the guidance of the sword spirit Xuanji, Gu Changyuan began to face his Taoist heart and tried to win back Su Nianwei, but found that she had found new faith in the demonic way. The war between immortals and demons is about to break out, and the love affair between him and Su Nianwei may be the key to breaking the situation.
