Chapter 646: Should I Be the One to Call Out?

Father and son glanced at each other as if by agreement, hastening their pace in a silent competition as they brushed past one another...

Bai Xingzhi had just exhaled, thinking he could slow down now, when a pair of white sneakers appeared in his peripheral vision. Glancing up, he nearly had a heart attack.

The very Bai Cheng'an, who should have already passed by and continued running, had somehow returned and was now running shoulder to shoulder with him!

With no choice, Bai Xingzhi straightened his back and forced himself to maintain a steady jogging pace, while desperately controlling his heavy breathing...

"Old men should know when to yield with age," Bai Cheng'an said irritably beside him.

Bai Xingzhi pouted angrily, flaring his nostrils and staring fiercely: "Old? You cheeky brat whose fur hasn't even grown in properly dares to call me old?"

"Just saying. If you're really not old, why get so angry?" Bai Cheng'an replied coldly.
