In addition to preparing for the upcoming battle, Elder Howard had to find a way to counter the power of the blood moon. He understood very well that his collaboration with the Werewolf God was solely to deal with Irving. Once Irving was eliminated, any cooperation between him and the Werewolf God would be impossible. They would likely become mortal enemies.
Therefore, before they turned into enemies, he needed to find a method to restrain the blood moon's power. The Werewolf God, before obtaining the blood moon's power, did not possess particularly strong combat abilities. It was the power of the blood moon that served as his greatest strength.
However, Elder Howard knew that discovering a way to counter the blood moon's power would not be easy. The nature of the blood moon's power was shrouded in mystery. Even the Werewolf God could only temporarily utilize its power, and he was unaware of how he had summoned it in the first place.
