At this moment, Lin Li stopped pretending, instantly changing his expression, and directly side-kicked Bai Bufan's butt, jokingly cursing:
"You idiot, Bai Bufan, what the hell were you studying this morning? Is that how you use proof by contradiction? Proof by contradiction = it won't work anyway, right?"
"Just tell me if I'm right or not?"
"Well, since the equation's been five cents per try, what else can I say, I'll just go along with you."
"Hahaha, I can't help it, man. When I'm solving math problems, my thoughts just scatter like that." Bai Bufan couldn't hold back himself and responded, finding it funny.
"Alright, let's go, time to eat."
"Let's go."
...
The five of them still took two taxis and headed to the restaurant that Ding Sihan shared in the group chat. Lin Li and Bai Bufan arrived first.
