Zhao Hai wanted to see if he could work with the demon beasts. If he could, he would have another powerful team in his Army.
But he couldn't rush to make contact with the monsters. He had to deal with the things in the nightmare world first. The monsters must have sensed the commotion, but Zhao Hai didn't know how the monsters would react when they heard the news.
Zhao Hai had been paying attention to the situation at the evil Wind Mountain. When the monsters heard that the nightmare world was being attacked, they didn't interfere. They just watched from the side. This gave Zhao Hai precious time to clean up the nightmare world.
Of course, Zhao Hai didn't kill everyone in the primitive world, but he didn't let go of some of the higher-ups of the sects. He didn't kill all of the ordinary cultivators of the sects because they couldn't cause any trouble. Zhao Hai didn't touch them.
