I recommend the Celestial Supporting Character Exchange Group. Zheng is in this book, but he's not the main character, but God's subordinate. In this light novel, there were other world protagonists under Lord God, such as Beria, Boros, and so on. This book wasn't a harem genre. Before the Beijing level, it was just a small plot, but before reading it, it was best to look at the settings in the comments section. I recommend this book because it meets the requirements of the title, and the plot is light and interesting, which is very suitable for relaxing. I hope you like my recommendation. Muah ~
