Standing on the city tower, letting out a long whistle and watching the Xiongnu army retreating, Liu Kun suddenly shuddered, widened his eyes, stopped, and listened closely. He asked those around him, "Did you hear that? Someone below is singing in response."
Those around him also perked up their ears to listen and vaguely heard some sounds, "It might be the refugees outside the city hearing the music and feeling inspired, thus singing a couple of lines in response."
Liu Kun listened intently for a while and became increasingly excited, "I didn't expect there to be such talent among the refugees. Quickly open the city gate and invite them in."
