The sun happened to completely set over the mountain at this moment.
At this time, the sky hadn't fully darkened, still resonating with the day's sunlight.
As the Undead Army attacked, the sky filled with dark clouds.
These clouds weren't purely black, but rather a ghostly green close to black, reflecting an ink-green glow with the flashes of lightning.
These ink-green clouds rolled and swelled in the sky accompanied by the lightning.
Various Ghosts and Evil Spirits, formed by souls, could be seen tumbling up and down within the clouds.
Various skeletal-shaped Energy Bodies circled around, trailing long paths behind them.
Shrill screams emerged in the sky, causing all living beings to feel dizzy and dazed.
Beneath the dark clouds, among the undead, was a conspicuous battle chariot constructed from the skulls of the dead.
The massive chariot was pulled by two gigantic rotting beast corpses.
