On the screen of the Sky Monitoring Instrument.
The "Void Cavity" below did not appear to have anything particularly strange about it.
Overall, it was an irregular oval, roughly three hundred zhang long, a little over two hundred zhang wide, and about one hundred and fifty zhang high. Its edges were jagged and uneven, as if something had gnawed at them.
The inner rock walls were covered in fine cracks, like a dried riverbed, or like the crisscrossing folds on a Dragon's back.
Judging from the scanned data, these cracks were not deep. The shallowest were only about an inch, and the deepest were no more than a few feet.
The reason all the data was approximate was that, under magical monitoring, it was changing every moment, as if it were alive. So the report summarized by the Sky Monitoring Instrument used rounded figures.
But on the Sky Monitoring Instrument's screen, that Void Cavity appeared to be nothing more than an ordinary lava cave, without the slightest abnormality.
That was very contradictory.
Jiang Yu looked at the data and images for a long time.
She still could not grasp the key.
As for the scan results of the energy field inside the "Void Cavity," they showed that the energy concentration within the cavity was extremely low, comparable to the depths of the Ruins of the Great Void. There was almost no energy or matter present, allowing the Sky Monitoring Instrument's probing waves to penetrate the entire cavity with virtually no loss and present an exceptionally clear internal structure.
Here, "clarity" itself was an abnormality.
In nature, a cavity with absolutely no residual energy was non-existent.
Rocks emitted trace amounts of Earth Qi, air carried free magic particles, and even an absolute vacuum would produce faint energy fluctuations because of quantum
