The invasion of the yaomo was Chen jingzhai's self-directed act.
It was impossible for him to help the 36 great cosmoses survive the catastrophe. If he wanted to improve the eight desolate universe, great worlds were the best resources. He couldn't miss them.
It just so happened that the evil Daoist had the demonic ring and was able to control and influence a demon that was close to the primordial realm. This made the demon invasion a powerful weapon in Chen jingzhai's hands, and he could use it to lure out the primordial realm demons from the great world of demons.
Just a moment ago, Daoist extreme evil sent a message saying that the demons were surprisingly used to this place. In fact, some demons didn't even do anything and their strength increased. This made the demons go crazy.
