After the Advanced Mathematics class, Professor Fang waved at Lu Huaiyu and gave a very smooth command.
"Send all the assignments to the office of the Mathematics Department."
Ning Li stood up.
"Professor Fang, I'll send it."
Professor Fang looked at Lu Huaiyu with a smile.
"There's no need, let him send them. My lessons aren't for free."
Lu Huaiyu walked over with a smile.
"It's my pleasure. I'll help Ah Li send them off."
Professor Fang snorted.
After all, he had to charge some interest for dating in his class.
Thus, Professor Fang led the two of them back to the Mathematics Department.
On the way, they were the focus of a lot of attention.
