As Chen Mo descended, he saw energy patterns etched across the walls of the entire deep shaft, and those patterns were still glowing.
This meant that the walls of the entire cave were part of an array. In particular, since those energy circuits were still lit, it naturally meant that the array could be activated at any time.
Frowning, he sent an urging thought to the King Beast beneath his feet. What if that black-and-white skeleton activated the array while he was descending?
Of course, based on his earlier observations, the skeleton probably could not use True Essence. Still, no matter what, caution was necessary.
His Spiritual Sense remained fixed on the etched energy patterns. Since he had not sensed any movement from them, Chen Mo temporarily relaxed.
The King Beast climbed rapidly downward, while he stood steadily on its back, as firm as a mountain and without the slightest sway.
The cave was incredibly deep, several thousand meters at least. The entire way down, it remained the same size and was covered in energy circuits. From this, it was clear that the array within this deep shaft had been an enormous undertaking, not something just anyone could have created.
If Chen Mo had been asked to make it himself, he definitely could not have created such a magnificent underground cavern. The etched patterns alone stretched for several thousand meters—how many resources would an undertaking like this have required?
He continued downward while marveling at it.
At last, he saw shimmering reflections of water.
Beneath the black shaft was a circular isolated island, roughly the same size as the shaft, though separated from it by several dozen meters. Around the island lay an Underground Lake, vast enough that it was probably the same size as the lake above.
He did
