This book is a historical script. The use of the Azur Lane design on the cover is purely for fun by the author, and the author thinks this picture is very beautiful. If readers are confused about the historical content of the book, you are welcome to comment and correct me. I have also made artistic changes to some of the history. The focus of this book will be on key events such as the Imperial Parade (A Different World), 1848, and Crimea. Readers are welcome to work with me to improve this book.
