The Love of the Immortal.

In ancient times, the Emperor God exhausted his cultivation to suppress the Demon King. Before entering seclusion, he reincarnated a trace of his essence as Han Mu. Unaware of this, Han Mu encountered Xuan Li, a demoness with innate demonic power, while cultivating in the Jiuchong Mountains. As they trained together, a deep affection grew between them, and they came to know and accept each other.
