Lady Du was the most inattentive, and over the years, she trusted Cai Wei more than herself. Since Cai Wei said so, she naturally had no reason to refuse. She decided to arrange for Dong Wan'er to live in the manor and wait until Miss Zhang gives birth before arranging for Lady Dong to enter the mansion.
Originally, Dong Wan'er planned to enter the mansion in the future and use the child in her belly to deal with Lady Zhang. Anyway, she didn't know if this child was Mu Chongwu's or not. She intended to use him (or her) to tackle Lady Zhang and win Chongwu's sympathy, and then slowly seek to regain his favor and rise in power. Eventually, there would be more children.
