Energy was in very short supply. That was Sarah's biggest problem with Luo Xia. Even Luo Xia had only just realized that he still had no idea what his intelligent robot subordinates actually relied on to keep themselves running.
He had seen Luo Fei chugging away at a gas can before, but apparently, not drinking the stuff didn't cause any real problems.
After hearing Sarah's explanation, Luo Xia finally understood. The AllSpark drew energy from another dimension to sustain itself. The Energy Activation Device he had created was more like a mining machine, continuously extracting energy from another dimension to replenish Luo Xia's supplies.
Likewise, intelligent robots had similar "mining machines" inside them. They possessed independent AllSpark energy-circulation systems. As they continuously absorbed energy from other dimensions to replenish themselves, most forms of energy, including solar and thermal energy, could also recharge them.
That was why the Intelligence Sequence was so precious. Activating each robot was equivalent to creating an independent AllSpark system, which was why there were such strict limitations.
"My energy reserves, along with this base's production capacity, have already been used up by more than ninety percent. But the mechanical forces we currently have are nowhere near enough to sustain a cosmic war. If you want to keep expanding your mechanical army, Master, you'll need to find another source of energy," Sarah concluded.
"Could Tony's Arc Reactor be an additional source?" Luo Xia asked.
"Any kind of energy would work, actually. It's just that Arc Reactors are too costly. You also can't monopolize all the raw materials on Earth for now, Master," Sarah said.
"No. Palladium is a little hard to get, but we could still try making a second-generation Arc Reactor." Luo Xia stroked his chin.
Once Tony's physical injuries had been dealt with, the problem
