In the chapter, Guan Xiao woke up on the train and found that the skinny uncle and little boy next to him were gone, replaced by a small man who claimed to be his uncle's friend. The short man claimed to have been entrusted by his uncle to take over Xiao Zheng, but when Guan Xiao Zheng tried to contact his uncle, the phone could not be connected due to poor signal when the train passed through a tunnel. Nevertheless, the small man's understanding of the uncle's family made Guan Xiaozheng relax his guard. However, when they arrived at Fengcheng Station and were about to board the train, Guan Xiaozheng noticed that the little boy and skinny uncle he had met on the train before were sitting on the train, which made him realize that something was wrong and he might be in danger.
