Millennium fox demon Tu Shanyao suffers severe damage to her barrier and is heavily injured, accidentally meeting forest protection team captain Huo Yunzheng. After a night of accident, she brings her son Xiaobao across a thousand miles to seek her husband. Outwardly she is a frail and sickly rural daughter-in-law, but actually she wants to borrow Huo Yunzheng's pure yang energy to repair her demonic power, living together as a fake couple, yet gradually growing true love amidst everyday fireworks. However, a crowd of ancient demon relatives from the shattered barrier rush over to seek refuge; black dragons, phoenixes, and all kinds of spirits flock together in the 1970s, working hard to learn how to be human and working to make a living, full of hilarious moments.
