章 61: Mathematical Modeling Competition; Hidden Mission Triggered

After Lin Fan returned to Jiangbei University, he went straight to Room 305 of the training building.

At this moment, the twins, Xia Bing and Xia Xue, were seriously designing a model in front of the computers.

When they caught sight of Lin Fan, their eyes glowed with excitement.

Then, they each took out a bottle of energy drink from their backpacks and handed them to Lin Fan.

"Thank you," Lin Fan said.

He casually opened the two bottles of energy drinks and took a sip from both.

When Xia Bing and Xia Xue saw this, the joy on their faces intensified, and a pair of cute little dimples appeared indistinctly.

At this moment, Professor Zhang Yong walked in.

When he saw Lin Fan, he immediately shouted, "Lin fan, you're finally here!"

When Lin Fan heard this, he could not help but rub his nose.

Last Saturday, Zhang Yong had been sending him messages, asking him to come early for the training.
