There were many, including Wu Yu who was disguised as Green Fire Demon King who received a harsh scolding from the 7-heavens demon kings for the tribute collection this time.

Many 5-heavens demon king were naturally unhappy over the scolding and had much complains, but none of them would dare to voice out their displeasure. Even Green Fire Demon King and Golden Bee Demon King who were on good terms would not dare to badmouth the 7-heavens demon kings secretly in order to vent their anger.

Regardless of how close they were, there was no guarantee that the one party would not tell on the other of the complaints made behind the 7-heavens demon kings' back. If word got out, then he would be doomed. He would no longer have a place in the Fiendish Underworld Metropolis.

These demon immortals basically trusted no one, regardless of how close the friendship was. There was always a risk of being backstabbed, especially when the situation benefitted the other party.

Hence, all these 5-heavens demon kings who were scolded basically left alone and returned to their respective palaces.

Of them, there were two who were punished and had to hand over their tributes...
