To say nothing else, Lian Manman knew this answer was absolutely "unfortunate" for Lian Yeye and Lady Zhao. Staying at the old mansion, perhaps Lian Shouli might still receive some "motherly love" and "familial affection," but all Lian Yeye and Lady Zhao could get was to walk back on the old path.
Lady Zhou's character determined everything. Facing the crisis now, Lady Zhou wouldn't do much to Lady Zhao and Lian Yeye. Once the crisis is resolved, that is after Lady Zhou has fully controlled Lian Shouli with confidence, she would trample on Lian Yeye and Lady Zhao even more than before.
A wife who cannot bear sons, with a weak personality and no natal family, and a "money-wasting" girl who would eventually be someone else's maid. In Lady Zhou's mind, she never regarded them as family or junior members. Lian Manman could even feel that Lady Zhou deeply despised Lady Zhao and Lian Yeye.
