At the moment Fang Yun made the first stroke of the character Yong, a faint sound of the brush slicing through the air could be heard, like the gentle snap of a whip.

Wei Yu's gaze sharpened. The most crucial aspect of this stroke in the character "Yong" is the speed of the brush, known as "swift descent with a sharp edge." If the brush isn't fast enough, the tip won't be sharp and steep, and it won't qualify as a sharp edge.

Wei Yu clenched his right fist tightly. Fang Yun's stroke had surpassed mere speed and reached a level of danger. Speed can be practiced, but danger requires a deep understanding of calligraphy.

"Sharp and steep..." Wei Yu couldn't help but mutter softly. This is the realm that countless calligraphers dream of achieving.
