Capítulo 78: Well-versed in the Three Teachings!

Lu Shu curiously asked the auntie who was extremely joyful, "Auntie Liu, what's happening between them?"

Auntie Liu pulled him away, "Don't bother about them. They're in a conflict now."

"If you can't do it, it means you can't no matter what, so save your breath," as Lu Xiaoyu coldly said

"What a joke. This old man here knows everything in the world and I can even solve this math question of yours. The only thing is that I can't express it in your XY method. When I was learning how to do calculations in the private school, you weren't even born yet!" as Li Xianyi said with disdain.

"How old are you?" asked Lu Xiaoyu

"81!" as Li Xianyi proudly answered.

This news was rather surprising to Lu Shu. This gramps used to be so sickly previously but Lu Shu didn't expect him to have maintained himself that well. From just his looks, he looked 50 or 60 at most.
