When the old man spoke those words, Wang Ruojun was intensely shocked inside; he finally understood what was happening. It turned out that the piercing and maddening music just played was Ten Sides Ambush.
This piece is basically impossible to perform with a single instrument or by a single person. The reason is simple: Ten Sides Ambush is a grand composition that involves the brutal battles of war and heart-stopping moments, with its tones constantly climbing higher. One instrument alone cannot withstand such escalating pitches, and performing Ten Sides Ambush on a guzheng can easily damage the instrument.
But Su Xuan managed to bring Ten Sides Ambush from its lowest to its highest point with just a guzheng. Those who don't understand would think it's noise, but those who do can feel the battle's brutality and the grandeur of Ten Sides Ambush. Imagine how this could not be heart-stopping.
