Gravel was everywhere along the awkwardly-shaped valleys.
After carefully cutting a huge reddish-brown rock, Shi Mu suddenly heard a violent roar coming from afar.
The sound shook the gravel on the hillside, causing it to roll down in a burst of smoke.
Shi Mu quickly retracted a few steps, squatting behind the giant rock, looking at the source of the sound.
In the depths of the valley before a huge bottomless cave, a giant bone elephant of more than ten feet was slamming left and right. It was jumping up and down, hitting its back in the process. From time to time, the rock walls and stones would pierce through its back.
Witnessing this scene, Shi Mu could not help but smile slyly. It reminded him of one particular black puppy in the small village. When summer was approaching, it would always circle around trying to scratch or bite its back due to the fleas in its fur.
Aside from the giant white bones of the big elephant, there was nothing special about it.
