Yin Cheng and Wu Li did not speak again. They had already seen through Si Fan's character. If he was already instigating Yin Mo to harm her own family now, who knew what he would do in the future?
Actually, there was another situation that Yin Xun did not mention. If Yin Mo became crippled and had nowhere to go, she would definitely return to the Yin family. When Yin Xun first read the original text, Yin Mo was treated as a spare organ farm by Si Fan. As long as it was an organ that Si Xia needed, it would be taken away from Yin Mo in the end. When Yin Mo was no longer usable, it would be time for Si Fan to completely abandon her.
Si Fan would eventually fall in love with Yin Mo for real, but that was after Yin Mo had been destroyed beyond repair and her family had all been killed.
Yin Xun knew that Wu Li and Yin Cheng would not believe her even if she tried to explain this.
