Su Ping found some information about the Blood Source Crystals from the Federation's database too. However, it only listed two of the item's usages: consolidation of small worlds and war creatures' modification.
The Blood Source Crystal could strengthen a small world once infused into it.
However, the crystal could never touch the blood of any living creature. Even if it accidentally touched a wound, it would still be absorbed into the body, corrupting the creature which would turn into a bloodthirsty animal with only fighting and killing on its mind.
Such usage was the first one detected. So, the crystals were applied to large-scale universal wars.
But then, people found that they could strengthen small worlds through further research; they were no longer wasted on war creatures after that.
