Fang Yun carefully observed Yang Yuhuan's finger technique as he listened, and the more he watched, the more he felt she had a natural talent.

The art of the zither is not easy. The right hand's techniques or combinations include more than thirty types such as supporting, wiping, picking, hooking, plucking, and striking, while the left hand has more than thirty types such as kneeling, crashing, lifting, pushing, unison, calling, and returning. It can be said to be incredibly complex.

Fang Yun had studied the art of the zither at Jiangzhou Literature Academy and even remembered many books on the subject. He could play and appreciate the music, but it would take a long time to reach Yang Yuhuan's level.

Fang Yun quickly noticed the flaw in Yang Yuhuan's technique - it was too soft. The force was insufficient where it should be strong, which seemed to be related to her temperament. If Yang Yuhuan had talent, her ability to kill enemies with the zither would be average. However, because she had this flaw, her talent in other areas reached a terrifying level. If Yang Yuhuan used the sound of the zither to assist rather than directly kill enemies, or even to harmonize, the effect could be several times that of an ordinary zither player.
