In a city 30 kilometers outside the Siege City.
Lu Yongshan, dressed in green camouflage, stood atop a tall building at the city's edge. He set down an instrument he was carrying and took a metal rod from his pocket, gazing at the distant city. Waves of "woo woo" sounds reached his ears, rising and falling in succession.
"The final step of the mission."
A cruel smile appeared at the corner of his mouth as Lu Yongshan inserted the metal rod into the instrument's slot, fitting perfectly.
