The author's writing skills are not bad, and the plot logic is smooth and smooth, which is already very good in online articles. A slight shortcoming is that the writing is not very strong. A large part of the plot in the article is covered by the narration to explain the description and psychological activities.

The level of this book would be even higher if the dialogue were designed.
