Since Skasa's Nest had already been breached, there was no need for Xiao Tianyang and Zhang Liang to remain.
The purpose of the Underground City was equivalent to that of a War Fortress.
However, the Underground City Plane's defensive methods leaned more toward guerrilla tactics and ambushes.
In other words, they would most likely not construct defensive lines as they would in a conventional war.
The Underground City Plane's defenses operated in squads, which were then arranged into a defensive perimeter using the One-Character Long Snake Formation.
Under normal circumstances, each squad should have contained between eight and twenty people, with more than half being rank-? professionals.
Yet Skasa's Nest had already been shattered.
Having lost its most fundamental regenerative property, the area's defenses were effectively useless.
Whether they would make a comeback or not, even if they truly returned to defend it, they could not possibly pose any danger to the Heavenly Martial Dynasty.
Yet just as Xiao Tianyang led the Tianwu Dragon Guards in retreat, Li Jing received a carrier pigeon message from Zhang Liang.
Its contents gave him considerable inspiration.
The most heavily emphasized information was none other than the location of Kankuli and the others.
From the very beginning, Li Jing had felt that the Ston Snow Region was the most difficult area to conquer.
Yet he had ultimately chosen that region as his target, so naturally, he had only taken the risk because he was confident.
The problem was that Xiao Tianyang had ultimately uncovered a troublesome truth for the Sixth Group Army.
The Void Faction might have been planning to use the Ston Snow Region as a breakthrough point.
Moreover, Xiao Tianyang had already discovered Kankuli and the others, along with thirty thousand elite soldiers of unknown origin.
But life was like filled chocolate.
