There was a slight vibration inside the canyon.
It was like a weak earthquake, nothing too obvious, but the vibration was real. It came from the ground in a stable frequency, like a heartbeat.
The remaining Earth Elementals in the canyon remained in place as if they were stuck. After a while, they gathered together and then drilled down below the altar into the ground.
About tens of kilometers away from the canyon, on the edge of the Emerald Mountains, there was a Dragon Cave built on its cliff.
