This Deal Was Really "Fair"

Time travel delivery system, huh. Standard large set meal! However, I really want to know whether this system understands the four words "fair trade"? The following words are all for the sake of introduction: you can skip the number of words, thank you! I'm a novice writer, so I'm not very good at writing, so please forgive me! My personal style is very strong, please don't spray it if you don't like it, thank you! But this is the truth This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
