The emperor accidentally discovered that the dignified and gentle Queen Su Qingyan was actually a nine-tailed fox. From the initial shock and curiosity to full love, he concealed the queen's identity time and time again to protect this special relationship. In the harem, the queen secretly holds a "monster tea party" and hides grapes in her greedy mouth. The two of them live a sweet and comfortable life. However, the demon Taoist Wu Xin of Beiyan invaded with the soul-eating beads, and the border was in a critical situation. In order to protect her family and country, the queen resolutely rushed to the front line. In the end, she used the secret skills of Qingqiu to fight the demons, risking her own life, and defeated the evil with the Tail of Divine Punishment. She used her actions to interpret her sincerity to the monarch and her country, and wrote a warm legend in which humans and demons guard each other and protect the world together.
