This ability greatly enhanced the strategic significance of the Mechanism Fortress.
Inside the Fortress, one could utilize its unique feature "Rock Gold Detection" to sense the environment through the rocks and metals in the ground.
These rocks and metals would carry the low-frequency pulses emitted by the Fortress.
Those within the Fortress could see on its walls the images detected by the Fortress.
Fang Mu had already entered the Fortress, and the images on the walls were exceptionally clear.
Although it was impossible to visualize the distant scenery in detail, all life forms were marked with special energy levels on the topographical map.
The Fortress, in combination with the Abdominal Territory Worm's detection, was already sufficient for use.
In fact, what surprised Fang Mu the most was the scope covered by the Fortress's unique "Rock Gold Detection" ability.
With underground mineral veins, "Rock Gold Detection" could monitor an area of six hundred kilometers in radius.
