The Stupid Legitimate Daughter Whose Engagement Was Broken Off Turned into the Cold-Faced Prince's Favorite

[The Queen of Arms × The Dark Prince, a dimensionality-reducing strike that makes your scalp numb] She is the feared ghost in the international arms industry. Once he traveled through time, he became Mei Kaishao, the good-for-nothing second lady of the Mei Mansion who had been stupid for ten years. The stepmother is poisonous, the concubine sister is ruthless, the concubine brother is evil, and even the fiancé, the eldest prince, broke off the engagement in public. Does everyone think she is easy to bully? Mei Kaishao smiled: I made more grenades than you eat. Brother Shu led people to beat him? A pack of dynamite teaches you how to be a good person. Framed by concubine in talent show? Homemade crossbow bolts pierce the mask of hypocrisy. The eldest prince regrets and wants to get back together? Sorry, go in line. Only the mysterious man in the silver mask bet on her to win from the beginning. "I bet on Mei Kaishao, and the bet is on me."
