"Teacher Zhang? Why are you here at my house?"
Nan Yan descended the stairs and approached the sofa.
Zhang Lingxian saw her coming down and then stood up. "Nan Yan, do you remember the favor I asked you for back then?"
Nan Yan nodded. "I remember."
Last time, Zhang Lingxian had approached her to help NTA Computing with the challenge from CSA Computing in M Country.
"Today?"
Zhang Lingxian nodded. "Yes, it's scheduled for this morning at ten."
"Oh."
The challenges from the Computing Institute were all conducted online, so she would go to NTA Computing instead of traveling to M Country.
"Have you had breakfast? If not, want to have it together?"
Zhang Lingxian quickly waved his hand. "No need, you go ahead and have your meal. I'll grab a snack on the way."
Nan Yan gave him a sideways look. "Teacher Zhang, you're being too polite."
