Invincible Shooting System

I really don't understand what this book means. Please forgive me for being too stupid.

It's still possible to write. . It's just that the writing is a bit jumpy. You can't understand it if you don't look carefully. . . . I hope the author can correct this problem

I hope the author can add more interesting articles in the first part to enhance the sense of immersion, otherwise it will be difficult to follow. Ps: Advice from a book friend who has been a book friend for almost ten years
