The fortress's energy storage device held 750 points of active energy. This was a very common storage method, and the energy could be converted into high-purity active ore at any time.
The Clan had strict requirements regarding the purity of active ore. The ore the pig-headed people mined was called "crude ore" and had to be washed, refined, and preliminarily purified before the fortress could absorb it.
Afterward, the fortress would purify it a second time to obtain active energy. This active energy could both maintain the fortress's operation and condense into active ore.
For such a colossal structure, its energy consumption was manageable as long as it stayed still. But once it moved, it needed a clear destination. Otherwise, the losses would be devastating.
According to Li Siniwei, given the current state of the ore vein, each pig-headed person could mine roughly 0.3 to 0.4 kilograms of active ore per day.
There were 643 pig-headed people in total, six of whom no longer mined. That meant 223 kilograms of active ore were obtained each day.
Think that was little profit? Not at all. Of those 223 kilograms of active ore, 80 percent had to be handed over to the "Clan Alliance." The remaining 44.6 kilograms constituted the day's earnings.
After deducting the fortress's rental fee, as well as the wages of the Clan guards, overseers, and staff, more than half of that 44.6 kilograms was gone. In the end, Li Siniwei's daily net profit came to around 3.5 to 4 kilograms of active ore.
This fortress did not belong to Li Siniwei. He had rented it from a large company in Fortress City, which was under the control of the "Watchtower." Now that he had secured the backing of the "Clan Alliance," he was naturally mining on the Alliance's
