Yun Qingqing, the supreme sect leader of the Mystic Sect, transmigrates into the body of a woman who shares her name. This original host was a noblewoman from the Zhenyuan Marquis Estate, betrothed to Crown Prince Xiao Zirui since childhood. Six months prior, a devastating fire at the Crown Prince's residence left the original host severely disfigured after she rescued him. Instead of gratitude, Xiao Zirui, influenced by Su Yurou, the Prime Minister's daughter, accused Yun Qingqing of arson and annulled their engagement. Humiliated and betrayed, the original host attempted to confront the Crown Prince during his dowry procession to Su Yurou but was pushed into a river and drowned. Yun Qingqing awakens in the water, fully aware of her new identity and the treachery surrounding her.
Recognizing Xiao Zirui as a man shrouded in black misfortune qi and entangled by a karmic thread, Yun Qingqing decides to sever all ties with him immediately. She publicly tears up the marriage contract, declaring she would rather marry a dog than the Crown Prince. When Xiao Zirui orders her arrest for insulting the royal family, Yun Qingqing intercepts the carriage of the Regent King, Xiao Changheng. Known as a feared, paralyzed, and blind imperial uncle, Xiao Changheng is actually a man of immense power and hidden abilities. Yun Qingqing, possessing Spirit Pupils that allow her to see fortune and fate, notices the Regent King is also entangled in fatal calamity. She offers him a deal: she can restore his sight if he helps her escape her current predicament.
Inside the carriage, Yun Qingqing uses a blood talisman to temporarily restore the Regent King's vision. Shocked to see her disfigured face but intrigued by her boldness and the truth of her words, Xiao Changheng agrees to her proposal. He publicly declares his intention to marry Yun Qingqing, seizing the betrothal gifts originally intended for Su Yurou and diverting them to the Yun Estate. This move not only saves Yun Qingqing from the Crown Prince's wrath but also humiliates Xiao Zirui and the Su family, who had planned to marry the Crown Prince that day.
Back at the Yun Estate, Yun Qingqing confronts her abusive relatives, including her second uncle and cousin Yun Bailian, who had manipulated the original host into her tragic fate. She slaps them for their disrespect and theft of her family's inheritance, asserting her dominance. The Regent King arrives with guards to protect his future wife, further intimidating the Yun family. A palace eunuch arrives with an imperial decree summoning Yun Qingqing, instigated by Prime Minister Su to punish her for defying the Crown Prince. However, Yun Qingqing arrives with the Regent King, who supports her claim. In the imperial study, she exposes Su Yurou's slander and forces her to apologize. The Emperor, aware of the Regent King's power, grants the marriage between Yun Qingqing and Xiao Changheng, scheduling it for the same day as the Crown Prince's wedding to Su Yurou.
During the journey back, Yun Qingqing suffers from spiritual soul instability due to the transmigration. She kisses Xiao Changheng to absorb his yang energy and stabilize herself. Later, she discovers her mother, Madam Yun, is dying from a vegetative state caused by a venomous curse. Using her metaphysical skills, Yun Qingqing breaks the curse and saves her mother's life. She also identifies that the court physician, Divine Doctor Tang, is under a sterility curse, which she resolves by providing him with a talisman. Meanwhile, the Empress consults the State Preceptor, fearing the Regent King's rising fortune. The State Preceptor detects the sign of the Heavenly Phoenix altering fate, suggesting Yun Qingqing's presence is changing the destiny of the Regent King and the empire.
