The Blood River was like a natural barrier that separated the resistance from the nether God Hall. Without the Blood River, the resistance would have been wiped out by the nether God Hall. Every time the nether God Hall attacked the resistance, they would first have to pass through the blood River. It was because of this that the resistance was able to withstand the nether God Hall's repeated attacks.
The two banks of the Blood River had become huge military camps. Fafa did not prepare any military camps because the troops here did not set up any military camps at all. The few tents and carriages were occupied by people of high status. The ordinary undead were just standing or lying there.
Zhao Hai used his spiritual power to scan the area. There were at least a few billion undead on both sides of the river, and the number was still increasing.
