Sterl felt that there was no need to be surprised by the existence of prehistoric civilizations.
Just like in the world before his transmigration, where dinosaurs once ruled the Earth, it was entirely normal for the Starry Clan and other races to have civilizations that predated the upper realms and lower realm.
Perhaps the previous civilization was destroyed by a calamity of immense power??
Sterl's thoughts wandered as he continued deeper into the underground palace.
He could sense that with each step, a power akin to his own profession began to ripple around him. With this power protecting him, there should still be some remaining resources deeper within the palace.
Tap.
Tap.
Tap.
The entire palace was excessively empty, and the surrounding silence was profound, leaving only the sound of Sterl's footsteps.
