Three-thousand-year-old Yun family ancestor Yun Ling, to overcome a love tribulation, cross-dresses as a man under the identity of the Qin family's eighth young master to audit classes at Haicheng University. Everyone mistakenly assumes she is a country youth clinging to power, unaware that she is the owner of Lanxiangju, as well as a divine doctor, hacker X, lyricist master Ershui, and design tycoon Sanshui. Facing schemes and prejudice, she repeatedly displays her strength and fights back. Qin family powerholder Qin Yanxi goes from testing and suspecting to proactively protecting her, gradually learning the secret of her longevity. The Guixu Society appears, the Yun family's old seal is stolen, and the Qin family's old grace is exposed, leaving Yun Ling facing a choice between returning to her tribe or staying in the mortal world. The two join forces to smash the Guixu Society's conspiracy of extorting wealth using the Yun family's name, and their destined love tribulation finally becomes a good match.
