It's a very readable book about strategy, with interlocking plots, and the part where Xiao's teacher died at the end really made me cry. All I can say is "Sir, you are righteous."
In fact, when I first watched it, I thought it was a PO show, after all, there were more cars, but as I got to the back, I became more and more excited. Finally, the BGM that matched the scene was played, which was really fun to watch, haha.
It's a story about strategy and tactics. When I read it, I was really shocked by the author's imagination. The plot is very reasonable and well-founded. I won't give any spoilers and just finished reading.
Personally, I think this book is okay, but some parts are not very rigorous, but you can ignore it. There is another book with the same worldview as this one, which I also recommend reading.
It's really beautiful, but the update speed is also very slow. It was only updated 25 years after it was written in 19 years, but it is now completed. I recommend it.
