After pocketing the last few snow-white stones, Ethan turned into a streak of lightning and shot straight into the cave mouth.
It was deeper inside than it had looked from outside.
The walls pinched in tight, the floor slanting downward. Eerie blue light flowed through the cracks in the stone like thin little rivers.
Ethan pushed forward. The air grew colder by the step, and the energy density climbed higher and higher. Before long, the narrow passage suddenly opened up, and he stepped into a massive underground chamber.
This place was nothing like the canyon above.
The surrounding rock was a deep, pitch black, but its surface was laced with blue patterns that looked almost naturally formed. In the center lay a wide open area, where that eerie blue energy kept surging up from below, forming one slow-rotating vortex after another in midair.
The vortices didn't make much sound, yet the whole chamber sat under a strange, suffocating pressure.
