"This kind of ruin entrance is quite rare," Ethan remarked as he gazed at the distinctive entrance to the Hot Spring Ruins.
Dark Lord Rock paused, then nodded in agreement. "Indeed, it is uncommon, but not unprecedented. Moreover, this site is a wholly new ruin, a particularly rare trial-type ruin."
Ruins generally fell into two categories.
The first category was the exploratory ruins, which comprised the majority of ruins found.
These ruins predominantly originated from various constructions left behind by ancient kingdoms after their destruction, such as the remnants of the Gama Empire in the Red Jade Valley.
Others were left by powerful forces or once housed mighty individuals.
Classified as exploratory ruins, these places might harbor valuable items, warranting exploration.
The other type of ruin was much rarer.
In other words, they couldn't be termed "ruins" in the traditional sense but rather normal trial grounds.
