Because this article does not have a complete "keel", all chapters are the product of the author's inspiration. Based on the author's past experience, if there is a "keel" and then writing the article, it will inevitably appear rigid. Moreover, readers will know the development of the main line by reading the introduction. In this way There is less room for imagination and pursuit, so there is no introduction to this article, only a few main characters. But the author can tell you that this article has many plots and twists and turns, but one thing is for sure, the whole article is based on a relaxed and funny tone. Thank you everyone!
