Chapter 1558: Fighting a Ruler

"Spirit mine?"

Xu Qing's eyes narrowed.

He had expected there to be a guardian here. Hence, Xu Qing wasn't too surprised by the appearance of this Ruler.

He had also expected the cultivation base of the guardian.

After all, this place was suspected to be the fifth star ring and could suppress flawlessness gods.

What really surprised him was what the guardian called this place.

Mines generally referred to resources. From Xu Qing's previous understanding, spirit mines should be mineral veins formed by spirit stones. However, looking at it now…

The mine in question was a process of refining gods. The essence of the gods was extracted, and then absorbed by the beings of the minor worlds. The essence was filtered by these beings, and then further filtered by the cultivators themselves…

As such, the spiritual energy extracted became extremely pure.

From this perspective, it indeed matched the theory of the spirit mine.
