The story takes place in the "Xuanli Realm", a cultivation star belt where the mind and body are intertwined. The protagonist Teng Siming is a ninety-eight-year-old mixed-race succubus with the bloodline of Jiuyou Zhuyin. Due to the backlash of the bloodline, he has been stuck at the peak of "Primary Heart" for a hundred years. He disguised himself as a storyteller in the Mortal Star Zone, and used "playing with people's hearts" to collect emotions to practice the "Yin Yang Reverse Chaos Art", and accidentally obtained the incomplete "Jingwei Sea Reclamation Art". Because he saved a mortal village and accumulated merit, he broke through to the realm of "accumulating merit". He was discovered by the deacon of "Qingwei Xuanmen" and introduced into the sect. He met Su Wanzhao, a female monk who betrayed Shinto due to different ideas. During his practice, Teng Siming gradually became involved in the battle for the "Crystal of Mind" and the expansion conspiracy of the "Aggregation of Faith: God of All Wishes". He used the talent of the succubus and the "Qiankun Zhengqi Spectrum" to deal with good and evil, but found that his most dangerous enemy was actually his master "Jingchenzi" who had guided him to get started, but because of the solidification of his Taoist heart, he always stayed in the state of "realizing Bodhi" and was jealous and dependent on him. In the end, during the great catastrophe of "saving all sentient beings", Teng Siming used the Fate Broken String Piano to cut off the cause and effect of his faith with the God of All Wishes, and helped Ji Chenzi break the heart barrier. He chose not to ascend to the sea of saints, but stayed in the Immortal Star Ring to establish the "Heart and Matter Academy" to open up a new path for those who came after him to balance detachment and belonging.
