Tui Zi turned on his flashlight and then walked to the right, using his hand to forcefully pry open the lid on this plastic barrel.
However, he couldn't open it with just one hand, so he clamped the flashlight with his mouth, holding the plastic barrel with one hand, and exerting force with the other hand.
The lid was sealed tightly; his veins bulged as he twisted, finally managing to open the lid.
A strong scent of pine oil burst forth.
Excitedly, Tui Zi aimed the flashlight into the oil barrel; the yellow, semi-transparent liquid—this was indeed pine oil!
This oil is extracted from pine trees, slowly flowing out. Collecting enough pine oil in a barrel requires dozens of pine trees.
Each pine tree yields a limited amount of pine oil. Before the apocalypse, there was a profession specifically for cutting open the bark and installing oil collecting devices; they were constantly busy in forests.
This might be the little house they built for resting temporarily.
