Selling Equipment Everywhere

The author doesn't pay any attention when working at home. The heroine's killer character is completely untenable. How is a killer trained? Even if you don't know, you can still make some guesses based on the nine-year compulsory education! The most basic literacy, recognizing people and objects; no matter where you are, careful observation, concentration, and vigilance should be engraved in your bones... But as for the heroine of this novel, in the few chase and fight scenes she appears in, she will be unwary, deceived, and dazed everywhere. It is comparable to a novice in modern society who has no social experience and no social experience... It is really unbearable to watch! This question is the cornerstone of the entire novel. Can't the author write characters who are logical and convincing?
