Qian Cangyi's feet stood on a resilient, curved object. Then, his legs bent slightly, and he started to exert force, propelling himself into the air once again. His body moved forward in the direction of the rubber ball while dodging a slap from the giant Fu Zhiyao's hand depicted in the painting.
Originally, the giant Fu Zhiyao had intended to strike Qian Cangyi but hit the rubber ball instead.
As luck would have it, the rubber ball's destination just happened to be on the path of Fu Zhiyao's retracting hand. Therefore, when the rubber ball reached its destination, it was smacked by the hand of the giant Fu Zhiyao as it was drawn back.
Under the force of this powerful hit, the rubber ball began bouncing back and forth at high speed along the boundary of the picture frame, much like a marble in a pinball game, seemingly never stopping.
