I swiped the screen, but I can't change the introduction. It's a bit old-fashioned. I wrote it casually at the beginning, but now I can't review it. It's said to be irregular. I regret it. The introduction doesn't look good [awkward laugh][awkward laugh] I wanted to change the title of the book, but I already thought about the cover, but couldn't change it. Just look at it like this if you can. They are all self-created. The cover can be changed, but the name cannot. That's it, no one is watching anyway, I will update it slowly
