Lu Ye walked into the cave entrance and ventured deeper, gradually sensing that something was amiss.
He had assumed it was merely a hidden cave where one could shelter and rest, but this cave was far too deep.
Thoughtfully, Lu Ye went to one side and examined it for a while. The rock walls on both sides of the passage bore traces of artificial excavation, and judging from those marks, they had been there for quite some years.

Lu Ye had once worked as a mine slave at Evil Moon Valley. Having gone in and out of mine tunnels day after day, year after year, he could tell at a glance whether this was a mine cave.
Perhaps many years ago, some valuable mineral had been buried here, and cultivators had found a way to excavate it. The mine tunnel left behind by the mining had simply remained.
There were many such places throughout the Cloud River Battlefield and even the Spirit Stream Battlefield, so it was nothing unusual.
Lu Ye did not have any particular designs on this place. This mine tunnel had existed for a long time. Even if it had once contained valuable minerals, they would have been mined clean long ago. How could anything have been left for him?
