As the sunlight slowly disappeared from my filling in the hole, Han grabbed an arrow from his quiver and placed it on the wall.
The next second, the tip of Han's arrow exploded, creating a small fire on it that allowed the arrow to serve as a torch.
Air wasn't a problem in this cave as there were multiple cracks that we made in the surface, allowing small bits of sunlight to pour in.
However, the holes in the ground were discreet and too small to be noticed by anyone... at least we hoped they were.
It wasn't like we could plant a tree down here for oxygen... could we?
Wait, could we?
Brushing off the stupid thought, I finished filling in the hole before heading over to Jin and Han who were making progress on the tunnel towards the center.
Checking the map, I made sure that our pace of digging forward was faster than the pace at which the borders closed in.
