This is the story of a senior time traveler who saves the world of tutoring. The heroine is not very powerful in her dimension, but her strength can still be beaten, eh! This is an anti-Soviet article! There are some quirks, but if you don't like it, don't force it! [Captain: Gui, do you know the sense of existence? Heroine: Captain! Please call me girl, I am a girl! Captain: Haha, boy, please treat the client who uses your presence as a bet well! Hostess:? Captain: Because they give everything to you and unconditionally believe in your existence as a stranger! Hostess: I understand, so, can you return my spiritual food to me? Captain: Hahahahahahaha. Hostess: Hey, don't act stupid! (PS: I am also incompetent in copywriting! If you can't understand it, forget it. The background setting and other things will appear in the form of dialogue in the first few chapters! Also, please note that the heroine is a scumbag! [Paralysis])
