An Ning scanned her surroundings but couldn't find any sign of Jiang Xia. 'Hasn't he checked in yet?'
She remembered his injuries. 'They should be mostly healed by now. There's no way he couldn't have gotten on the train, right?'
"Sis— what are you thinking about?"
"P versus NP."
An Guoping, who had asked the question, wanted to slap himself. 'I really need to learn to keep my mouth shut!'
An Guoping couldn't even tell if An Ning was just messing with him or if she was actually thinking about it.
After her calm reply, An Ning started doing stretches on the spot to warm up.
Seeing this, the others also began to warm up, getting ready to run.
Ten minutes later, their run began, with An Ning in the lead and the others following in a neat formation, their footsteps falling in perfect unison.
