At least, in the people Zhang Jingyao had seen, they didn't have such skills like Yang Ming and Wang Xiaoyan did. The difference in speed was tremendous. He had been in the underworld for so many years, but he hadn't seen people with such speed.
Perhaps, Yang Ming's moves were very simple, and there was no skill at all, but his speed was very fast. Zhang Jingyao also read a lot of martial arts novels. He deeply admired the phrase in them, 'Among all the martial arts, only speed is invincible!'
In other words, exquisite Kung Fu is useless. As long as the opponent was quick, he could give you a lethal hit before you could even make a move. It was just like the charging time in online games. Before you finished charging, you can be killed in one move.
