The cave network.

MC POV

The sphere kept descending slowly but soon came to a stop.

My mental power extended outward, and I realized I wasn't in an underwater area.

I twisted my hand and withdrew the energy. Immediately afterward, a blade of destructive, piercing spatial energy formed in my right hand. With a light motion, I sliced through the foam.

Taking gentle steps, I moved outside. The place was completely dark. Thanks to my mental power and Odin's Eyes, I was able to see the interior clearly.

The caves were made of reddish-gray and white stones, reminding me of rocks like granite and diorite. Stalactites and stalagmites decorated the surroundings.

I didn't stop there—I extended my sensory abilities through my Skill.

It spread across several kilometers.

Fortunately, I only sensed weak, non-threatening energy sources.
