Chapter 6

"We have arrived at the safety line." The scout of the team, Reid, used his spear to pry open some of the stones on the roadside, looked at some inconspicuous markings on the corners, and said quietly, "If we go further, there is no telling what we will see."

The so-called safety line referred to the boundary that was explored and cleared by the soldiers. For this cave, it was the dividing line between 'safe' and 'dangerous' areas.

The cave they explored was located on the western side of the Barren Mountains, adjacent to Rye Town. In order to guard against potentially dangerous things in the cave, soldiers in Rye Town would come here to explore and clean up once every three months, avoiding the proliferation of monsters such as gnomes, and avoiding dangerous creatures.

The safety line was the sign that they left behind before they left, after each exploration and cleanup.
