Master Deng did not give an immediate reply to Yuan Zhou's words. Rather, he continued speaking.
"Among tricks, there is one called Three Immortals to the Cave, performed with a pair of chopsticks, two bowls, and three balls. Phantom Hands, Master Wang, is the best at this performance. Under bitter training, his hands are so fast your eyes won't be able to follow them. A lot of times, he wasn't even using any tricks. He was merely moving the balls from one bowl to another," said Master Deng.
This was quite a simple concept. When one's speed surpassed what the camera and eyes could catch, one would not be able to see it. Yuan Zhou did not say anything and waited for Master Deng to continue speaking.
