The battle suddenly erupted.
The Undead Army roared like a tsunami, unexpectedly not with chaotic, bounding attacks, but rather forming bone array chains in organized formations.
Although the formation was simple and the movement still somewhat chaotic, perhaps not achieving perfect unity, a formation was still a formation. This was the first time human cultivators had seen another side of the undead creatures, indirectly proving that these beings were indeed organized. The organization might still be primitive, but once formed, it would eventually mature.
A collective formation of seven thousand undead creatures, not to mention these beings, would be difficult for humans to fully exert their collective strength.
