Episode 19 recap: Nan Qi Guo's behind-the-scenes instigator is arrested.

Tu Qian Zhou found the Grand Eunuch on the stage of the final competition, but he didn't expect the Grand Eunuch to possess exceptional martial arts skills. Taking advantage of Tu Qian Zhou's inattention, the Grand Eunuch kidnapped Wan Yu. When he was about to kill Wan Yu, Tu Qian Zhou caught the knife barehanded, causing his hand to bleed. He fiercely stabbed the Grand Eunuch, who, before dying, threw a torch in an attempt to ignite the gunpowder and perish together with them.

Tang Quan and others arrived at the grand stage, where the Grand Eunuch had set an ambush in advance. Since Wan Yu had no martial arts skills, Tu Qian Zhou continuously protected her. The Chief Supervisor claimed that Huan Xi Guo was attacking their country and advocated for a military response. They had no choice but to compensate various regions. Originally, he, as the son of a prime minister, had been living well, but it was now Huan Xi Guo enduring humiliation for many years, all for the sake of seeking revenge.

Unexpectedly, the Secret Execution Division was involved; otherwise, their plan would have succeeded long ago. Tu Qian Zhou found the Grand Eunuch on the stage of the final competition, but he didn't expect the Grand Eunuch to possess exceptional martial arts skills. Taking advantage of Tu Qian Zhou's inattention, the Grand Eunuch kidnapped Wan Yu. He demanded that they accompany the former King of Nan Qi Guo in death. When he was about to kill Wan Yu, Tu Qian Zhou caught the knife barehanded, causing his hand to bleed. He fiercely stabbed the Grand Eunuch, who, before dying, threw a torch in an attempt to ignite the gunpowder and perish together with them.

Jin Xin Xin skillfully caught the torch, averting danger. The Grand Eunuch was also captured, while Wan Yu fainted. Tu Qian Zhou carried Wan Yu back to their room to rest. The next day, Tu Qian Zhou and Shu Chen pleaded with Guo Zhu on behalf of Wan Yu. The princess also interceded for Wan Yu, highlighting her contributions to the country's salvation. However, Guo Zhu emphasized the importance of rewards and punishments. At this moment, Jin Xin Xin presented ten thousand written petitions, exerting pressure on Guo Zhu. Considering Wan Yu's circumstances, Guo Zhu ordered that merits and demerits should be offset. Although Wan Yu was a woman, her dedication to music and the joy she brought to everyone was enough to prove her qualification to stand on the stage. Guo Zhu allowed Wan Yu to perform as a musician, and Jin Xin Xin took advantage of his achievements to request the emperor to write a calligraphy for him.
