The group stepped outside the main hall, finally feeling relieved. The tension inside had been so high that they were on the verge of breaking into a sweat.
"What was that…?" Dong Lei asked hesitantly.
"Who knows?" Wang Teng shook his head.
"Why did the sky suddenly turn dark?" They all turned their gaze towards the sky, perplexed.
There was a patch of sky on top of the buildings. The previously bright sky was now gradually turning dark.
But, the speed at which it darkened wasn't like a normal transition into night.
Even Wang Teng couldn't discern the mechanism governing day and night in this place.
Within moments, the entire sky had turned pitch black, and even the heaven-stage martial warriors felt as if they were plunged into utter darkness.
Evil!
The darkness in this place was so complete that it was impossible to see anything at all.
