The weaker Angels and heavenly creatures had all slowly turned into streaks of light and flashed straight into the gate, disappearing behind the clouds and the light.
The same went for the demons.
The weaker demons all turned into balls of darkness, and soon, they were dragged back into the deep ocean or straight to the underground where the Gate of Hell was located.
The evil spirits also worked hard to retain many strong demons to stay outside of the gate.
Because the casualties on their side were not much, the spirits on the dark camp managed to retain a lot more strong demons on the battlefield, even if the stronger demons were still not summoned back yet.
Anyway, after the gate was completely closed, the battlefield would be more deserted and only the Spirit Battlefield wouldn't change.
