Everyone thinks Princess Vivian plays with magic. In truth, she plays with minds, timing, and cold logic. When she steps onto the emperor’s birthday stage, the entire court realizes this is not a show—it’s a takeover.

The episode opens in the Chen Dynasty court, where the Second Prince Qin Hao accuses his elder sister, Princess Qin Xi, of three crimes: forcefully marrying the top scholar, tarnishing the royal family's reputation, and endangering the state as a "demonic woman of a fallen kingdom." He presents a cloth strip found in a fish's belly as evidence of "heaven's will," intending to seize control of the Dali Temple. Princess Qin Xi calmly counters each accusation. She first calls upon the top scholar, Fu Ningyu, to clarify in court that their union was consensual. Then, she attributes her unrestrained behavior to missing her deceased mother. Finally, she skillfully turns the "heaven's will" argument back on him, declaring herself to be a destined figure meant to revitalize the kingdom, thus averting the crisis.

In front of the Emperor, the Second Prince Qin Hao accuses the Eldest Princess Qin Xi of being a disaster to the nation and attempts to have her executed. Remaining calm in the face of danger, Qin Xi uses a chemical trick to make the words "Son of Heaven's Mandate" appear on white paper, successfully proving her innocence. Qin Hao then sets a new trap, proposing that Qin Xi be responsible for receiving the formidable Yan Kingdom delegation. Qin Xi turns the tables on his plan, accepting the challenge and demanding that the Emperor promote her beloved Fu Ningyu to the position of Minister of the Court of Judicial Review, with the condition of thwarting the Yan Kingdom's efforts, thus successfully transforming the crisis into an opportunity.

Princess Qin Xi confronts the top scholar Fu Ningyu, and the two reach an agreement to propose annulment of their engagement to the Emperor separately. Fu Ningyu is puzzled by Qin Xi's unusually straightforward attitude, finding her very different from before. They seal their promise with a pinky swear, agreeing not to go back on their word. However, that night, Qin Xi's personal maid Cui Ying sees a disheveled and pale Qin Xi in her room, mistaking her for a ghost in her terror, leaving a cliffhanger for the plot.

Princess Qin Xi, having lost money gambling, must personally craft a birthday gift for her father, the Emperor. The Second Royal Consort and Fu Ningyu's maternal uncle, Bai Wen, arrive to provoke her, revealing that Qin Xi must compete in a talent show against Yan at the birthday banquet. If she loses, not only will territories be ceded, but she will also be forced to marry the one-eyed old general of Yan as a concubine. Scholar Fu Ningyu appears and coldly informs Qin Xi of Chen's dire military threats, expressing his disbelief in her ability to win. To reclaim her dignity and resolve Fu Ningyu's resentment towards her, Qin Xi makes a wager with him: if she defeats Yan at the banquet, all their past grievances will be settled.

Yan Kingdom's Ninth Prince Ji Zi'an arrives in Chen with envoys, intending to reclaim Luocheng, leased to Chen ten years ago, through a literary competition at the Chen Emperor's birthday banquet. He also plans to humiliate Princess Qin Xi, hailed as the "Son of Heaven." At the banquet, Ji Zi'an openly issues a challenge: if Chen loses, not only must Luocheng be returned, but Qin Xi will also be forced to marry an old Yan general. Meanwhile, Qin Xi's brother, Second Prince Qin Hao, fans the flames from the side, mocking her tardiness as cowardice and plunging Qin Xi into a predicament of internal and external strife.

At a state banquet between the Chen and Yan states, the Yan delegation proposes a literary duel. Fu Ningyu, the top scholar, worries that Princess Qin Xi is not skilled in literary contests and volunteers to participate, but is obstructed by the Empress and Second Prince Qin Hao. They provoke Qin Xi by citing her as "the child of destiny," urging her to compete. Qin Xi resolutely accepts the challenge. The Yan envoy then publicly insults Qin Xi by mentioning the "father dies, son inherits wife and concubines" custom of the Lu family. The Ninth Prince of Yan, Ji Zi'an, sets a trap, demanding Qin Xi compete in poetry with Li Xian, the renowned poet of Yan. The rules appear lenient but are designed to be impossible to win. Before the competition begins, Fu Ningyu anxiously tries to stop Qin Xi.

This episode follows Qin Xi, the Eldest Princess of Chen, as she accepts a literary challenge from the Yan delegation at a banquet. The first round pits her against Li Xian, the Poetry Sage of Yan, in a poetry contest. Li Xian presents a subtle poem about lotuses, earning widespread admiration. However, Qin Xi, armed with modern knowledge, effortlessly wins with a grander and more expansive poem about lotuses, "Leaving Jingci Temple at Dawn to See Lin Zifang Off," astonishing everyone. The second round is a painting contest. Qin Xi confides in Fu Ningyu beside her that this is her weak point, yet she appears confident. Fu Ningyu watches from the sidelines, his perception of Qin Xi gradually shifting as he is drawn to her confidence.

At the Chen Kingdom's emperor's birthday banquet, Yan Kingdom envoy Jin Yuan engages in a battle of wits with Chen Kingdom's Eldest Princess Qin Xi. In the second round, a painting competition, Jin Yuan's "Butterflies Playing Among Peonies" is highly praised, while Qin Xi's "Divine Bird Phoenix" drawing is ridiculed for resembling a chicken. Qin Xi pretends to hold back, but in reality, she provokes Jin Yuan to enter the third round. Jin Yuan proposes a challenge in illusionary arts, his forte, intending to humiliate Qin Xi completely. Unfazed, Qin Xi bravely accepts the challenge, escalating the confrontation between them.

At the Chen Kingdom's emperor's birthday banquet, the illusionist Jinyuan from Yan Kingdom's magic performance drew thunderous applause from the entire hall, save for Princess Qin Xi, who remained unimpressed. Faced with a provocation from Prince Ji Zi'an, the ninth prince of Yan, Qin Xi, in order to defend her nation's honor, decided to compete with Jinyuan in illusion. She borrowed Fu Ningyu's adornments and, on the spot, cast advanced hypnosis on Jinyuan, making him mistakenly believe he was the Nine-tailed Fox demoness Daji, and he proceeded to strip and fawn publicly. Although this move disgraced the Yan delegation, it also angered the second prince Qin Hao. He immediately accused Qin Xi of cheating, escalating their conflict.
