Shen Mingzhu, a concubine who was trying to survive in the Shangshu Mansion and was more transparent than a little girl, was suddenly packed up and sent to the Prince of Qin's Mansion, which made the whole capital fearful. Mission: Marry your sister-in-law. Target: Xiao Yan, the king of Qin who is rumored to be violent and disabled in both legs. Shen Mingzhu made some calculations: The prince is disabled and has a bad temper, and there is a high probability that he will not live long. If she beats him to death, she will be able to sit on the palace's property and become a happy salted fish rich woman. This time she will not lose money! She covered her head with a hijab, happily thinking about the future, until a hand with sharp bones lifted it off. The man in the wheelchair had deep eyes and a cold tone: "Be safe and stay safe for the rest of your life." Shen Mingzhu nodded obediently: "Don't worry, Your Majesty, I understand." She knows how to be an inconspicuous backdrop! However, late that night, when she got up to pour water, she saw her "bad" husband standing steadily by the window, giving orders to a dark shadow. Shen Mingzhu: "..." Xiao Yan: "..." Their eyes met and the air froze. In order to save her life, Shen Mingzhu was forced to sign a "sale contract" and became the "princess partner" of the boss of the underground intelligence boss. During the day, she was a relay station for gossip information among the ladies; at night, she was the most capable intelligence analyst around him. Just with this cooperation, why is the atmosphere getting worse and worse? At first, Xiao Yan said: "We are just a cooperative relationship." Later, Xiao Yan held her in his arms: "Whoever touches my princess will touch my life." Shen Mingzhu: Help! You agreed to be a salted fish, but why did you get a business establishment?
