[Cunning and charming + unruly and noble + villain's power strategy + age difference + two-way redemption + group portrait palace fight] Everyone in the world knows that the daughter-in-law of the Prince's Palace of Maoyin County is gentle and dignified, suitable for marrying into the royal family, but they don't know that she is good at hiding her clumsiness, arithmetic, martial arts, and is familiar with war strategies. Not even a time-traveling girl, a vicious and stupid female supporting character, but someone who disdains small tricks in the inner house because she only plays tricks! — — — King Zhennan, who had just won the battle and was summoned to Kyoto in advance, was blocked by Yu Xinlang.

The man on the horse looked at the girl in front of him with deep eyes. He thought she was here to ask for marriage. Little did she know that what she wanted was not marriage, but... Your Majesty, please be my sharp sword, and let me be your counselor, okay?
