At the end of the old street, there is an ancient Yin Yang Zhai. Shen Yan is the seventh generation in charge. The Shen family has been obsessed with it for generations, but it bears the curse of shortening its life span - she will not live to be twenty-five years old.
Until the thousand-year-old nine-tailed green fox Cangye appeared from the shadows. Three hundred years ago, he made a fox pact to bear the penalty of losing his life for each generation of Shen family leaders, but now he only protects her.
Ancient Zhai rules: Kindness and crazy thoughts can be overcome, but ruthlessness and betrayal cannot be redeemed. The woman who comes to seek help from the fox fairy secretly casts a curse on her love rival and is deprived of her half-life marriage; the merchant who betrays his wife and climbs a high branch scatters all his wealth; the young man who truly regrets kneels in front of a bronze mirror to look at his dead mother's remnant soul. After clearing up the cause and effect, Shen Yan found that the green light at the end of the night was getting lighter day by day.
The afterimages of old-style women - heavy snow, wooden houses, torches, plum blossoms and silver hairpins - flashed in the bronze mirror. She remembered that it was her previous life, when Shen Heng, the spirit-traveling witch, was protecting a little green fox that was seriously injured from a calamity. That fox is Cang Ye. He waited for a thousand years and used nine fox tails to extend her life that had been lost for thousands of years. Now there are only a few left.
However, Xuan Yan, the Taoist ancestor who surrounded and suppressed them back then, has returned from reincarnation and is secretly collecting resentment and refining sorcery, waiting for Cang Ye to exhaust his cultivation and seize the origin of the Nine Tails.
There is no luck in the world, and there is no way to survive in ancient times. Only for his obsession that spanned thousands of years, she came to replace him.
