Yu Mixi was exhausted now. Another two circles were a big challenge for her. Thus Gu Ning didn't give her much pressure.
As for Mu Ke, Gu Ning wouldn't hesitate to torture him.
"Mu Ke, run after me at the same speed, now," Gu Ning said, then ran ahead first.
Mu Ke immediately followed up.
He had intentionally slowed his pace down when he had been running with Yu Mixi. Now with Gu Ning, he could enjoy the feeling of running like a wild horse.
Though Gu Ning was running fast, she knew this wasn't a race.
Mu Ke knew it as well. Physical training wasn't the same thing as race. He didn't run pass Gu Ning on purpose, but remained behind her.
After a circle, Mu Ke started to be out of breath. Two circles later, Mu Ke fought for his breath. After three circles, Mu Ke was exhausted and gradually was left behind by Gu Ning.
Then Mu Ke found out Gu Ning's pace of running was all the same, no matter how many circles she had run.
