Chapter 173: Return to the Surface

In the pitch-black cave.

Liu Yan relied on his A-grade skill, Shadow Cloak, and B-grade skill, Traceless Silence. He had become one with the darkness, and no one could detect him at all.

Meanwhile, the four mine thieves not far away had already packed up their tools. They turned on their mining lamps and headed in Liu Yan's direction, preparing to return to the surface.

Liu Yan also noticed that the man in the lead was carrying a special box on his back. The ice chalcedony should be inside.

Although the other three mine thieves had also carried some things, they were all placed in their backpacks. They should only be some rare ores.

Seeing that the four mine thieves were carrying a full load, Liu Yan could not help but laugh. These mine thieves were really insatiable.
