A lazybones wakes up to find himself transmigrated into a strange Western fantasy world. Everyone here can use magic, even ordinary people. Everyone, that is, except him: he can't use magic, and he's an undocumented outsider.
This is a big problem. Everyone sees him as a little kid who hasn't grown up yet, the sort who might shatter at a touch.
He Chaolin, who's twenty-five this year: ...Thanks, but I'm an adult.
With no other choice, He Chaolin returns to his old line of work to make a living, transforming into Fortune-Teller He.
"Hey, miss, want your fortune told? Only ten Heru coins. You can't go wrong, and you won't get ripped off!"
"Hey, sir, your glabella looks dark. You'll have a bloody misfortune soon. Want to buy this blessed Buddhist bracelet to ward off evil?"
"Hey, little dragon, no, big dragon, want to buy a crystal ball? It lights up and tells fortunes!"
The lazybones protagonist is always fooling around. Nine out of ten things he says are lies, and the tenth is a lie too.
Reader's guide:
The whole cast dotes on the protagonist, treating him like a little kid, while the protagonist treats the whole cast like little kids to fleece.
Theme: Even in adversity, keep pushing upstream
