"Excuse me, could you repeat what you just said... something triangle?"
Hearing this, the two girls, who were already a bit surprised by the fallen books, were momentarily stunned and then looked up at Xu Yun.
The tall girl gave him a peculiar look and said:
"It's just Yang Hui's Triangle, what's up with that, fellow student?"
The other girl, named Yueyue, was a bit more observant, and her gaze lingered for a moment on the student card Xu Yun was idly twirling in his hand – the graduate student card and undergraduate student card are different colors. Although it wasn't clear if the guy in front of them was a master's or a doctoral student, alumni at that academic level theoretically shouldn't be unaware of Yang Hui's Triangle.
So, subconsciously, the girl felt that this guy in front of her was probably just looking for an excuse to strike up a conversation.
