Chapter 813: 257. Ironclad Evidence of the Hidden Chamber 3

This little thing resembled a miniaturized drilling car.

The drill bit, forged from high-performance magic alloy, had been enchanted with multiple effects by Noland Lee, enough to break through the hard underground rock layers.

Noland named it the Drilling Mechanical Spirit.

He placed it on the ground, activated the array with "Mind Control," and watched as the Drilling Mechanical Spirit burrowed into the ground level.

To see the outside of the hidden chamber more clearly, Noland equipped this little device with a luminescent array.

When it reached about one meter above the hidden chamber, Noland activated the luminescent array, and in the well-lit field of magic vision, he continued to control the mechanical spirit to drill downward.

After drilling down another meter, with a slurping sound, the drill bit found empty space, leaving a round entrance on the floor.

Water-blue energy radiance scattered out from the entrance, falling into Noland's magic vision.
