The blood fiends were fighting and devouring each other. The first Blood Fiend King was fighting with the new Blood Fiend King.
Roars shook the sky, and blood-colored spiritual energy overflowed everywhere.
The human experts watched silently.
Although they knew that if the blood fiends continued to fight, and more powerful experts would be born, they had no way to stop it.
After all, it did not matter if they died at human hands or their own; they would still grow stronger.
What they could do was to try their best to delay the blood fiend race's invasion. They needed time to find a solution.
The infighting continued for a month, after which the blood fiends were unified, and they began their invasion.
They broke through the human's twelve great formations.
The battle became more intense.
