Gravis talked with Orpheus some more, and he had also gotten the answer how it was so cheap for the Research Institute to open portals to other worlds. After all, something like that needed a lot of Energy.
The answer was as obvious as it was brilliant.
Prisoners from Opposer City's Guards.
The Research Institute and the guards had a deeply connected relationship, and one could even say that one of them nearly couldn't live without the other one.
The Research Institute gave the guards plenty of techniques and Form Laws in exchange for some of the prisoners. All the prisoners that only had to work for a finite amount of time would be sent to the mines to mine God Stones, from which a huge part would go to the Research Institute.
However, the prisoners that had committed severe crimes wouldn't be sent to the mines but to the tubes.
