If it wasn't for Masen's quick reaction, the backpack might have hit him on his feet.
When he felt the weight of the backpack, his face changed dramatically.
How was it possible?
He could feel that the weight here was the same as that of the other backpacks, all 20 kilograms.
It was not at all the empty bag he thought it was!
In other words, Xia Xibei really ran 800 meters with a twenty-kilogram backpack on her back!
Moreover, she was so fast!
This was simply beyond his imagination.
How was this possible?
As if Xia Xibei didn't see his expression, she asked indifferently. "Is there anything else? Can I continue?"
Looking at her innocent expression, Masen looked as if he had eaten something unsavory. His expression was very ugly.
He wanted to say something, but in the end, he just handed the backpack back.
"Go on."
He couldn't didn't believe it. Could Xia Xibei really keep up this speed?!
"Okay."
