Lin Yanta, a young man with a black cat in his arms, made an appointment with Xia Jiyan and planned to confess his love under the 13th peach tree. Unexpectedly, that night, Xia Jiyan was mysteriously brought back to ancient times by the strange girl Zha Lan. First, he accidentally traveled to Chang'an in 672, where he met the Holy Lord Murong Yan in white, and was misunderstood by him as his unmet fiancée Nangong Aoleng.
When he entered Chang'an to avenge Nangong's family, Xia Jiyan was abducted by a masked dancer dressed in black. He used the poison as bait and forced her to dance the Gu Heart Dance. Performed a dance for the canonization ceremony of Prince Li Hong of the Tang Dynasty. The purpose is not to perform a dance, but to take the prince's life. Just before the dance ended, the fragrant aroma of peach blossoms filled the entire glass stage. After a puff of smoke, the dancing woman disappeared.
