wait so the baby is Yi Yun’s and some other random women’s egg. Or is it Yi Yun’s and the aunt’s... Hoeyang
Probably a surrogates. It would be creepy if it would be the aunts and i remember something about her having problems with having a kid soo (not sure though).. and considering her age surrogate is a more likely option
Remember the chapter that someone told Jin Yao that Yi Yun's embryo that was frozen was stolen?
I think they thought that egg was Feng Jin Yao's and stolen it
