When the demon Dragon King heard the Great Demon King's words, he was stunned for a moment. Then, he immediately understood what the Great Demon King meant. That's right, it was just as the Great Demon King had said. They used to believe in the demon God, and that Demon God was just a fake. It was to collect the power of belief, and that Demon God had not given them any benefits.
If they entered Zhao Hai's space, things would be different. The environment there was stronger than the devil World, and Zhao Hai was a good person. As long as they gave him power of belief, Zhao Hai wouldn't make things difficult for them.
Most importantly, there was still the threat of the underworld. If they did not enter Zhao Hai's space, they would have to face the underworld sooner or later. Who knew how many of them would die? once they entered the space, they would not have to worry about this problem at all. This was a great thing for them.
