In an era when the demons are in power, they are the masters of the despicable cultivators and mortals. The cultivator elders deem it necessary to send someone back in time, to determine the origin of the demon lord and to prevent his awakening. Li Su Su accepts the mission, becoming the mortal Ye Xi Wu, General Ye's third daughter who is married to Tantai Jin, the hostage prince and future demon lord. She is determined to destroy Tantai Jin, who in the future will massacre many. But as a witness to Tantai Jin's past life and rise to power, an unexpected tale emerges, one complicating her quest.

Xiang Yun was originally a cloud, but was turned into a fairy by Yue Laodian, and started working in Yue Lao Pavilion. Chu Kong is a disciple of the Uri Xingjun constellation. He strayed into Yue Lao Pavilion and was treated as a villain. Chu Kong accidentally broke Xiang Yun's fan, so the two quarreled and accidentally messed up the red string, which led to the marriage of the three worlds. The Jade Emperor knew about the chaos, and his punishment to them was that they could not go back to heaven until after the seven lives of love, and so their story began.

The mysterious death of Wu Mei Niang's newborn sparks rumors that it was murdered by the childless Empress Wang Nijun. To clear the Empress' name, her former lover Ming Chongyan and friend Helan Xiner investigate, uncovering a deeper conspiracy to seize control of the palace.
