Ye Jingshan was watching the video recording of Xia Fei and Chen Dong's fight in his office, and he used a pencil to outline the inconceivable dodging motions that Xia Fei executed on a piece of paper.
There was hardly anyone in this day and age who would use such a primitive tool like pencil and paper. It was much easier to use brain-imaging or computer-assisted drawing than to do it by hand, but Ye Jingshan still maintained this tedious and inefficient habit of hand-drawing. He was convinced that it was the act of manually drawing things that could increase his personal understanding of the moves.
Ye Jingshan's hand-drawing method was simple yet effective, and a combination of a few lines was all it took for him to very clearly depict the crux of Xia Fei's movement.
Tapping his pencil on that quarto-sized notepad in his hand, Ye Jingshan fell into deep thought, dense wrinkles gathering on his forehead.
