Lei Dong's Cave Heaven Blessed Land was currently in the process of opening. One year inside the Cave Heaven Blessed Land was equivalent to ten years in the outside world. If he kept gathering Chaos Crystals, Lei Dong would have a chance to raise his Hidden Dragon and Fierce Ghost Armies to a level where they could sweep the world, making them not much weaker than the Night Emperor's forces. Add the Alliance Army led by the Netherworld Ghost Emperor and the others, and Lei Dong was completely confident they could suppress the Night Emperor.
Of course, they didn't need to wait a year. Even now, if the three sides truly joined forces, they could suppress the Night Emperor. Lei Dong had only ever revealed fifteen hundred Nascent Soul level Hidden Dragon troops and thirty thousand Fierce Ghost troops defending the city.
In fact, throughout the fighting so far, Lei Dong had continuously rotated his subordinates on the city walls, concealing two-thirds of the true strength of both armies. This was something not even the King of Holy Radiance, who had been attacking him all along, knew—not to mention that even Lei Dong's true allies had little idea.
The sixty to seventy percent of his forces that he had kept hidden were the source of Lei Dong's confidence all along. They were also why he wasn't the least bit afraid of facing the King of Holy Radiance and the Lord of the Abyss together.
The Void Refining stage was indeed formidable—so formidable that Lei Dong didn't want to meet it head-on. But on a battlefield of this scale, even someone at the Void Refining stage couldn't defy heaven and overturn the tide alone against a sea of troops. Their greater purpose was to intimidate the enemy and lower their morale
