All of this was within Ye Yinzhu's calculations. Including the obvious figures of the six Tower Masters floating in midair, the sudden ambush by the two Abyssal Demon Kings, and the appearance of the golden light shield now, all were within Ye Yinzhu's precise calculations and planning.
Three years of preparation were by no means a waste of time. Ye Yinzhu knew that the greatest threat from the Abyssal Plane to his own side were the Four Great Demon Kings. As long as the Four Demon Kings could be destroyed, then the balance of this war would immediately tilt.
However, the only one on their side capable of reaching the peak offensive power of the Ninth Rank Sub-God rank was the Little Dragon Lady. Including Ye Yinzhu himself, aided by a Divine Beast, they could only confront two Abyssal Demon Kings head-on. What about the remaining Abyssal Demon Kings? Fill the gap with lives? Of course not.
