By the time the crowd realized that it was just an afterimage, and by the time the afterimage disappeared, three seconds still hadn't passed. In the third second, the crowd could clearly hear the lightning sound.
In the twinkling of an eye, Jiang Chen appeared once again in the place where his afterimage had just disappeared. He stood there as if nothing had occurred. However, the hourglass came to a stop when he came back. Everyone was dumbfounded and looked in disbelief at the hourglass. They were all startled by what they witnessed. The time was clearly written on the hourglass. Three seconds! His results were better than Wu Ziming's.
When one speed reached the extreme, the unit of measure used to measure one's progress wouldn't be just seconds, but milliseconds. Improving by just a single second could be considered a great improvement. No one here had a hope of catching up with Wu Ziming's achievement, but Jiang Chen's achievement was even more exaggerated.
