Black Jade Mine

"It's because of the mine below. The torrent in this place is entirely different from other places." The captain explained after seeing everyone's doubt.

Yun Lintian scanned the surroundings and didn't see any living beings nearby. Around seventy kilometers below, he discovered a strong whirlpool twirling into a cave entrance. This must be the Black Jade mine.

"Everyone, follow me closely. Do not go out of the path. Otherwise, you might be swept away by the torrent." The captain warned solemnly.

Everyone's expression became serious as they were aware of the consequences of being swept away into the powerful torrent. Their life would be difficult to be preserved.

The captain didn't explain anything further and dived toward the cave entrance, followed by Yun Lintian and the rest.
