Synopsis：In the later years of Emperor Zhenzong’s reign, a young Bao Zheng and his close friend Gongsun Ce collaborate to solve a long-buried injustice. The female lead, Yue Liang, lost her entire family over a decade ago due to treachery. Determined to overturn the verdict, she learns of the legendary Yin-Yang Mirror, said to distinguish truth from falsehood. She breaks into a tomb to retrieve it but triggers a trap that imprisons Zhan Zhao. To save him, one must decipher complex mechanical puzzles and mathematical riddles within the underground chamber. Desperate for help, Yue Liang encounters the exceptionally intelligent Bao Zheng. She devises a scheme using ghostly legends to lure him into the crypt to rescue Zhan Zhao. However, Bao Zheng, who upholds justice and fairness, refuses to believe in supernatural tales. After successfully freeing Zhan Zhao, Yue Liang obtains the mirror and reveals the truth: her family was murdered by villains who remain at large. To reopen the case, Bao Zheng exploits the legend of the Yin-Yang Mirror to stage a reenactment of the crime. The psychological pressure causes the perpetrators to confess out of fear, leading to their arrest and conviction. This victory catapults the young Bao Zheng to fame, gradually establishing his reputation among the people as a symbol of fairness, impartiality, and justice.
