When I returned back to Earth in between my travels into these two worlds, I made sure to warn Lily about that point.
She asked for warriors, attracting my attention to this point that I totally missed.
I took out a great number of warriors and spread them all over the capital region and beyond. Things looked a bit chaotic but I didn't care at all. I left behind enough stat crystals in mountain sized gatherings and let my warriors consume them.
As I kept jumping in between the two worlds, releasing my shields, fierce offensive attacks, gathering up bones, and helping my forces out there if needed by using my techniques, I kept releasing more warriors after the old ones upgraded themselves and replenished the lost stat crystals.
My gains from these crystals were still going on from the battles at the two worlds out there. In addition to the bones, I kept taking out half of their inventories as well.
