Golden Finger Has No Effect on Me

Sui Tan, the second legitimate daughter of the Duke of Qin, returns to the capital after years of exile in a separate courtyard. Upon her arrival, she immediately clashes with her half-sister, Zheng'er, who was born to a concubine and has been favored by the Duke. The conflict centers on an invitation to the Empress's spring hunt, which Zheng'er attempts to usurp. Sui Tan aggressively reclaims the invitation, drawing the attention of Lin Qi, an imperial hidden guard assigned to protect her by her fiancé, the Third Prince, who lies in a coma. The Duke, initially furious, is deterred by Lin Qi's status and the political implications of the Third Prince's faction, ultimately siding with Sui Tan.

At the spring hunt, Sui Tan faces public scrutiny and gossip regarding her fiancé's condition and her own reputation. She publicly defends the Third Prince's honor with bold, arrogant rhetoric, silencing her critics. The tranquility is shattered when a commoner woman is found dead, and the prime suspect is revealed to be Sui Tan's elder sister, Suizheng, whose engagement was broken by the victim's lover, Young Master Sun. Suizheng is arrested by the Dali Temple, leaving Sui Tan desperate to prove her sister's innocence.

Sui Tan and Lin Qi investigate the murder, discovering that the Imperial Physician Hu has been manipulated using a puppet technique. They trace the manipulation to a mysterious, invisible figure who attacks them, leading to a chase that ends with Sui Tan and Lin Qi falling into a hunting trap. They realize the attack was a diversion. Sui Tan deduces that the victim died days before the hunt, meaning her body was moved using corpse-manipulation arts similar to those used in ancient battles. This evidence clears Suizheng's name, but Young Master Sun, the suspect, escapes from the Dali Temple dungeons.

The escape draws the attention of Zhu Yan, the Minister of the Court of Judicial Review, known as the Jade-Faced Judge of the Underworld. Zhu Yan arrests Sun Cheng and interrogates the family, revealing a cold, calculating nature that frightens Sui Tan. Despite his reputation, Zhu Yan shows unexpected courtesy to Suizheng, sparking Sui Tan's interest in matchmaking them. She schemes to force a proposal, using her status as the Third Prince's fiancée to bypass her father's objections.

During a meeting with Zhu Yan, Sui Tan accidentally reveals knowledge of thirteen assassination attempts on him by the Liao tribe, a secret she should not know. This slip raises suspicions in Lin Qi, who confronts her about hidden truths. Before they can resolve the tension, Zhu Yan returns with news of Sun Cheng's escape. Sui Tan and Lin Qi pursue the case, suspecting the same invisible manipulator is responsible. The story concludes with the conspiracy deepening, linking the murder, the escaped prisoner, and the supernatural arts to a larger threat involving the Third Prince's past and the stability of the dynasty.
