One hundred thousand years ago, Empress Nuwa gave birth to a baby boy named Qingcheng of the Celestial Clan, and kept him in captivity in the Longmen Cave of Biji Mountain, waiting for her to resurrect the Nine Heavens Xuannv with Qingcheng's heart 129,600 years later.
Thirty thousand years ago, in order to avoid disaster, a male fox from Tushan stole Kuafu's walking stick and jumped into the dragon gate, where he met Qingcheng by fate. Nuwa was furious and ordered her disciples to hunt down the demon fox for 30,000 years, causing her to suffer the pain of having her heart and bones ripped out for ten lifetimes.
When the spirit of the demon fox was gone, Qingcheng did not hesitate to sacrifice the heart of the human emperor of the Celestial Clan, and used her body as a sacrifice to protect the body of the demon fox from decaying for thousands of years. At this point, there is no hope of the Nine Heavens Mysterious Lady being resurrected, and a wisp of her remaining soul turns into the Sleeping Beauty in the West Mountain of Kunming and never wakes up. Nuwa drew a sea of blood from the underworld and burned herself in front of the Dian Lake, turning her body into a blood curse, causing the two of them to carry the memories of countless lives and endure the endless pain of endless reincarnations.
In the 101st life, they went round and round in the ups and downs of the world and finally met. The two work hand in hand to practice medicine in Kunming, one at Minghua Hospital, and the other runs a private clinic. They use the legend of the dragon lock in Changchong Mountain to clear up the old grievances of their fathers and heal half-life regrets in the world. In the end, they break through many tribulations and break away from the shackles of fate. Together they go to Bingzhong Luotian Outer World, which the little fox has been searching for for 30,000 years.
