Great Tang: One Edict to Grant Him a Period, and Cheng Yaojin Loses It

In the sixth year of the Zhenguan era, the land enjoyed a bountiful harvest, and Li Shimin held a grand feast for his guests. That day, Li Zhi transmigrated into the future Emperor Gaozong, who shared his name, and awakened a System that made him stronger whenever he provoked someone. At the banquet, Cheng Yaojin performed a Whirling Hu dance to honor the emperor. Li Shimin asked his sons what reward they should give him. Li Zhi blurted out, “Give him a menstrual period!” The ministers burst out laughing, and Cheng Yaojin was left fuming. From then on, he set out to keep provoking the Zhenguan court, one minister after another. Yet he could always produce all sorts of useful inventions and technologies for the Tang Dynasty, leaving the Zhenguan court both fond of him and exasperated by him. Zhangsun Wuji: “The prince is great. It's just that he can't keep his mouth shut.” Li Jing: “It would be wonderful if His Highness the Prince of Jin didn't have that mouth.” Li Shimin: “Sometimes I just want to poison this rebellious son and shut him up for good!”
