The logic here was exceedingly simple. Someone had made moves against the four sisters of the Xiao Family; now, only Xiao Yebai remained. The problem was that Yebai was well known as a profligate with nothing to his name. In that case, the only option left was to set their sights on his wife, Gu Nuan.
Xiao Yebai, who cared deeply for his wife, would surely help if he saw Gu Nuan's maternal family in trouble. The adversary must have thought their move was quite astute. However, they hadn't anticipated that both Gu Nuan's father and mother were without money, not even a penny to invest, and trusted their daughter implicitly. They would tell her everything, especially after Gu Nuan demonstrated her capabilities during the Qiu Sangui investment affair, which only increased their trust in her. Thus, the only option for their adversary was to target other relatives of the Gu Family.
