In the royal study, she exposed the secrets of the ministers one after another, but was unexpectedly granted the title of Imperial Shang Yi. The information she unintentionally revealed later not only helped the emperor to verify military pay and gain insight into the marriage conspiracy, but also caused turmoil in the court and completely changed his own destiny.
