Looking out, they saw an immensely vast ring-shaped pit.
The bottom was flat ground, while ring-shaped mountains like a barrier surrounded the entire plain! Though they had flown very high, they still had not cleared the barrier formed by the surrounding mountains.
Moreover, the pit was so enormous that, without careful observation, one would not even realize they were still inside it.
Once invisible, Huo Yushen had more attention to spare for surveying the surroundings.
On the east side of the ring-shaped pit stood rows upon rows of black tents, stretching everywhere as far as the eye could see and covering nearly a tenth of the pit's area.
On the west side, black smoke drifted from rows of pitch-dark openings, like entrances to Hell.
To the north stood mountains formed from piled-up mineral deposits.
These mines stretched on endlessly, resembling a vast, unbroken mountain range that occupied at least a quarter of the ring-shaped pit! And they were no ordinary minerals!
Huo Yushen's gaze suddenly sharpened.
He could see clearly that at least three of those "mountains" were entirely Black Silver ore, from which the Special Metal Black Silver could be refined!
He scanned them with the detection system of his Da Siming Liuguang Gold Mecha and found that the Black Silver content in the ore was at least seventy percent! That was twenty percent higher than the Black Silver ore Xia Chujian had found on Senze Star! He just did not know how extensive the overall deposits were...
Huo Yushen estimated the size of those "mines," puzzled by how the mineral deposits here had directly formed mountains. Were ore veins not usually underground, requiring excavation?
At this moment, Xia Chujian also turned her gaze toward her surroundings.
She did not look at the mines to the north, but at
