From the author of the same book as Love Between Fairy and Devil? Jiu Lu Fei Xiang. Based on the trailer where Changheng made his cameo, thess two stories could potentially be set in the same universe.

Starting Yang Chaoyue from Dance of the Phoenix and Xiang Yun from Romance of Tiger and Rose, these two are a much anticipated pair for the new iQiyi xianxia drama.

Dramawiki synopsis:
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
