The fiery red fox Chi Yan has been practicing in Qinglan Mountain for hundreds of years, but has never been able to completely transform. In an accident, she rescued Liu Mingyuan, a descendant of the Liu family who was being hunted, and became involved in a thousand-year dispute to protect the dragon veins. The two went from suspicion to trust, from fighting side by side to being connected. In the end, Liu Mingyuan's soul scattered and turned into rocks in order to protect Dragon Vein and Red Flame. Chi Yan awakened Qingqiu's bloodline and took over the important responsibility of guardianship.
In order to save Liu Mingyuan, Chi Yan, with the help of his mother Bai Li and the demon clan, bravely entered the nether world to find the reincarnation stone. After going through the test of life and death on Huangquan Road, Naihe Bridge, and the Sansheng Stone, he finally exchanged the fragments of the Reincarnation Stone at the cost of "guarding reincarnation forever". Liu Mingyuan's soul reunited and returned, but he lost all his memories...
When the hundred-year contract expired, Chi Yan turned into the guardian spirit of reincarnation. Liu Mingyuan, who lost his memory, searched for his wife in the world and finally discovered the truth. One person and one spirit, across the cycle of life and death, embark on an eternal guardianship that transcends time and space...
