1987, Shenzhen. Shen Qingci was recalled from London by the Shen family. The reason was that the eldest sister Shen Wanqing was missing and the planned marriage between Gu and Chen had to be replaced by someone. As a concubine, she had no right to refuse. But she handed over a contract - she could marry, and she would serve as Gu's chief negotiator. On the wedding night, Gu Yanzhi warned coldly: "Don't try to secure Mrs. Gu's position." Shen Qingci smiled, turned to the negotiating table the next day, and spent three hours helping Gu take down 20% of his opponent's profit. After that, Gu Yanzhi found that his substitute wife was getting more and more out of control: she made the century-old British-owned foreign companies bow their heads, made the Hong Kong governor's special commissioner give in, and even made his competitors offer sky-high prices to poach people. He began to wait outside the study room late at night, watching her review the contract, and handed her a glass of hot milk out of nowhere. Until he witnessed another man putting a coat on her at a cocktail party, and he overturned the champagne tower on the spot: "She is mine." But when Zhou Xiaoqiao, the real Bai Yueguang, flew back from London, Shen Qingci took off her wedding ring and left the house. Gu Yanzhi thought she would beg for mercy, but instead received a "Gu's Bankruptcy Risk Early Warning Report" drafted by her. Half a year later, she returned to the negotiation table with a brand new business plan. Sitting across from her was a red-eyed Gu Yanzhi. "Shen Qingci, what conditions do you want this time?" She turned to the first page of the document: "Article 1, abolish the Gu family's marriage rules."
