"That’s right, but we’ve kept the Human Clan penned up for over ten years now, and besides confirming the opportunity’s location is around the mines, what progress have we made?"

The Demon Emperor pondered for a moment and shook his head.

They had tried sacrifices, attacks, and even forcibly tampering with the mines, but none yielded any results.
