Before Hong Yu was no longer a pitch-black cave.
Here stood a massive hall, crafted entirely from brilliant, transparent crystal.
A brief inspection revealed to Hong Yu that it was carved from a single, complete piece of crystal, not pieced together from separate fragments.
This was a staggering realization.
A piece of crystal this massive had to weigh well over ten million pounds. Even an expert at the Primordial Spirit Realm would find it difficult to move.
Perhaps an expert at the Yin Yang Realm could only just manage to budge it.
But to carve it into such a magnificent palace? That would be incredibly difficult—an impossible task, even.
"What the hell is this place?" Hong Yu muttered to himself.
His eyes scanned the area, but he found nothing out of the ordinary. He then used his Spiritual Power to probe his surroundings, yet still detected nothing amiss.
Only then did he begin to cautiously approach the massive palace.
