All the deities were watching the grand battle of the gods.
However, the outcome of the battle was unexpected, mainly because it was too brief.
Under normal circumstances, as long as the Koutao Mermaid Goddess stayed within her Divine Realm, those three Grand Dukes of Hell could have turned the Water Elemental Plane into fish soup in vain.
Therefore, those deities who could potentially intervene hesitated and did not immediately take action.
After all, the fight hadn't even started; intervening now would only make them cannon fodder. Helping the Koutao Mermaid Goddess was not supposed to be like this.
They still had a long time to wait until her Divine Realm was found and invaded by Hell. It could be decades once the battle started, right?
