The kidnappers had simply pretended to be debt collectors and gone to ask Shao Qiyun questions. Shao Qiyun didn't even have to be forced before telling them everything. However, when she'd been asked which of the children was the most pampered, she had said that the four older siblings were the most pampered and hadn't mentioned Xiao Wu. Therefore, the kidnappers' main goal at the start had been four children. Of course, they wouldn't mind kidnapping a fifth as well.
Unexpectedly, an accident had happened. In the end, only two of them had been kidnapped and they'd even ended up getting caught.
Shao Qihai had been hospitalized for three days. He had recovered quite well and could be discharged now. It was only after he was discharged that he discovered Shao Qiyun's role in this kidnapping incident.
