As Quantum Holdings' first factory in Iowa used top grade equipment from other planets, it was also the first on Earth to have a production standard that was on par with the other factories in the Alliance.
There were three of such factories in Europe and Asia, and if all of them started producing, they could create 1200 energy-shield boosters every twenty-four hours.
In order to maximize the efficiency of the factory, they were equipped with smart tools from the Alliance. Not only were they beneficial for the production of the energy-shield boosters, once the company launched a new line of machines or electronics, the factory could promptly switch production with great flexibility.
The four factories cost Quantum Holdings over eighty percent of its capital reserves. It could be said that Xia Fei had spent sufficient money in building these factories.
