The underground world of the Moon.
In the subterranean space beneath the main mining base, silver liquid metal suddenly gushed out with a whoosh, pouring like a waterfall from the deep central shaft that led straight to the Lunar Surface!
These were the roughly 500 tonnes of Mechanical Insects Nie Yun had dispatched. They had cleared and leveled the shaft along the way, and now they had finally completed their task and reached the underground base.
This meant... Nie Yun was about to begin large-scale extraction of the energy crystals in this underground space!
As soon as the mass of liquid metal landed, it transformed into nearly ten thousand small robots. Their stubby legs carried them into every corner of the base's core area to repair equipment, replace parts, and upgrade the mining technology.
The original Ant Robot production workshop was replaced with Nie Yun's small Robot Production Line, while the spherical mining vehicle factory was repaired, modified, and brought back online...
After lying dormant for tens of thousands of years, the base showed signs of civilization once more!
The enormous base spanned more than a hundred kilometers. Even this many robots vanished into it like drops in an ocean. They could only occupy a few key functional buildings and core areas before they lacked the capacity to expand any farther. Fully absorbing the resources within this base would clearly take some time.
Repairing and modifying the existing base was far faster than building an equivalent mining operation from scratch. Including the subsidiary mining bases already underground, this mining system left behind by the extraterrestrials would save Nie Yun a considerable amount of time.
The vast quantities of steel inside the base also gave the Mechanical Insects plenty of material to consume. Though it had deteriorated badly, it was much
