I can't directly provide the title of the novel or the plot summary because these are all personal preferences and memories. However, I can provide you with some hints that might be helpful: The common plots in fast-acting novels included traveling to different worlds, experiencing various life experiences and stories in different eras. Some novels even involved emotional entanglements and conflicts between characters. You can search online novel websites such as Qidian Chinese Network, Xiaoxiang Academy, etc. according to the story plot and theme of the novel, combined with relevant search keywords. At the same time, he could also use some novel recommendation engines such as Douban Reading and Jane Book Reading to recommend novels that he might be interested in based on his preferences and search history. I hope these tips will help you find the novel you want.
