"Zhou Botong was terrified, he ran like crazy. Qiu Qianren was known as the ‘tie zhang shui shang piao’ [iron palm floating on the water]; his lightness kungfu was superior from Zhou Botong’s. If he was not scared of Zhou Botong, he would have caught up with him early on. "
So Qiu Qianren can catch up to Zhou Botong when Zhou Botong is terrified and trying to run away with all his might...
...but he isn't able to run AWAY from Zhou Botong?
WTH?
