PS: The composition of this book: 49% original plot, 30% ship girl plot, 20% Marvel plot, 1% other plot
PS2: Because it is a pseudo-history written by the author according to his own understanding and ideas, it is inevitable that there will be situations where familiar characters are OOC, and all plot developments are required by the story.
PS3: By the way, in order to avoid causing controversy, the orientation of this book is oranges, not marriage.After all, what the protagonist likes is the boiler room with the big Lai Lai and the long-legged hate monster....
PS4: If the score of this book is good, I will update it on P station.
