"Huh! So you're Mu Shanshan! The daughter of Zhiyuan's sister." Wu Xiuli spoke with a sarcastic tone. She had been wondering who these clueless people were! How familiar they looked. Turns out they're the daughter and son-in-law of He Rongshan, whom the old man keeps mentioning.
Originally, she was somewhat unwilling for Mu Shanshan to return. After all, that would mean less inheritance for them in the future. Especially with the old man constantly mentioning He Rongshan, there's no guarantee he won't soften and do something foolish.
But that's not the point now. Mu Shanshan's husband tormenting her own son is something she disagrees with, so she's the first to oppose Mu Shanshan's return to the He Family.
