When Nick arrived at the Lava Mountains, the monster horde was still about half a day's journey away.
Nick decided to take advantage of this time to rest and check the temporary camp set up by Irving and the others in the middle of the Lava Mountains. After all, the Lava Mountains were a very important location. Irving and the others might return here after this.
First, Nick assessed the general condition of the temporary camp. The defense infrastructure of the camp was still intact. Although the camp had previously been attacked by the Lava Giant Legion, Irving, James, and the others had worked together to fend off the assault. In that battle, the Lava Giant Legion suffered significant losses. As a result, the Lava Giants no longer dared to continue their attacks on the temporary camp.
