Several days passed, and the presence of the undead in the North had largely disappeared.
It wasn't that there were none left, but nearly all of those fleeing south had done so already. Others either did not want to come from the east or had not left the Plague Swamp at all.
According to some information sent by the Undead Mages, Zhao Guang speculated that most of the Undead Mages would not want to leave the Plague Swamp. After all, it was only here that they could preserve themselves best.
It was here they need not worry about harm from the outside world, and thus most of the Undead Mages had already chosen their sides.
No matter which Legendary Mage it was, after all, each was a legend, not so easily defeated.
Indeed, the conflict between the two Legendary Mages gradually tended toward a balance. The key point was that as the battle progressed, the lower-tier fighting had mostly faded into insignificance.
