The kids indeed didn't believe it. Who would believe such an explanation? Maybe Shao Qihai had also given the same explanation to his new wife and children, denying his relationship with the five of them completely.
Shao Qihai felt very helpless. "It's true. Little Dong, you have to believe me. I was only there to protect and transfer them to another place. I can't say much about their identities and circumstances, but what I've said is true."
He wasn't lying. He had indeed transferred the wife and children of a man who had died in the line of duty. In order to avoid revenge on his remaining children, he had transferred them away.
Although he had transferred them to a place where no one knew them, they had also changed their names. He had to completely forget their appearance and address.
