Lin Yu'an stood up as he spoke, beginning the most important security measures of the night.
"In a place like Ailao Mountain, a fire can dispel the cold, but it also attracts curious or hungry visitors from the dark. So before we rest, we must first establish a safe defensive system for ourselves."
First line of defense: Clearing the isolation zone.
He cleared away all the fallen leaves, dead branches, and humus within a two-meter radius of the shelter's rock wall, exposing the solid soil beneath.
"Most night creatures, especially snakes and venomous insects, rely on the leaf layer as camouflage and cover. Clearing this area is like taking away their 'cloak of invisibility,' leaving them with nowhere to hide as they approach."
Second line of defense: Constructing an elevated platform.
