If you don't move into Yingyue Palace, there's always the possibility of various accidents happening outside. If Cheng Mei Ren's child meets any mishap, it'll be easy to shirk responsibility. But if she moves into Yingyue Palace, where Lady Jing has absolute control, then Nangong Shuangshuang will have to ensure the safety of Cheng Mei Ren's child.
If anything happens to Cheng Mei Ren's child in Yingyue Palace, Lady Jing would be unable to defend herself even with ten mouths. That's why Lady Jing asked Nangong Shuangshuang if she could guarantee the safety of Cheng Mei Ren's child.
Nangong Shuangshuang pondered this. Given her control over Yingyue Palace, she's confident she can protect Cheng Mei Ren's child from harm, as long as Cheng Mei Ren obediently stays within Yingyue Palace and doesn't wander outside.
After careful consideration, Nangong Shuangshuang nodded and said to Lady Jing, "If Cheng Mei Ren moves to our Yingyue Palace, I am confident in protecting her child."
