The advance force continued to the deeper parts of the tunnel, where the mining pits had finally run out.
The young commanders and their companions began to proceed with caution, inspecting every nook and cranny. After ensuring there were no anomalies, they proceeded boldly.

The young commander gritted his teeth, instructing his men to completely clear the boulders in front. At this point, his entire demeanor expressed frustration.
