The new baby is a baby from the sem*n that was supposed to be Feng but since Feng's was used in rourou, it is from yi. The new baby is from yi. Feng aunt used that semen because she thought Feng didn't had a first born, that way she would inheritance the company.
so rourou isn't yi yuans child but fens? soooooo how did yi get a hold of rourou? also who is the new baby that I saw a couple chapters ago?
