yes, it's Yingluo. after a while, Gao Hanqiu, who was holding the phone, was completely dumbfounded.
On the other end of the phone, a familiar, aged voice could still be heard.
"You brat, you came up with questions that are beyond your syllabus, and you blame others for using methods that are beyond your syllabus to solve them! What, I'm a retired tutor, is that against the law? Ah, you still want to teach me a lesson, don't you?"
"No, no, no. How would I dare to teach you a lesson?" Gao Hanqiu had already stood up from his seat and was listening to old Cao's lecture.
"I'm telling you, your Little Junior Sister is my last disciple. Don't give her any trouble. Also, don't give her too much homework in the future. If there's anything she doesn't understand, I'll teach her. You're not allowed to bully her!"
Old man Cao said this for his own good.
He didn't want to have to change his handwriting every night to do high school level mathematics tests.
