Whether Zheng Peilin had appeared after Yan Xiaokai went to Shen City needed to be analyzed according to the specific plot of the novel. Some novels might only mention Zheng Peilin after Yan Xiaokai went to Shen Cheng, while others might not mention her at all. If Zheng Peilin only appeared after Yan Xiaokai went to Shen City, then she might need Yan Xiaokai's help in the plot or she might need Yan Xiaokai's help to complete the task. In this case, Zheng Peilin and Yan Xiaokai might establish a relationship or continue to get along after Yan Xiaokai left. If the novel did not mention Zheng Peilin at all after Yan Xiaokai went to Shen City, then Zheng Peilin might not have played a very important role in the story. This depended on the plot and theme of the novel.
