Where did those resources come from? From destroying the hundred passes the humans lost or had to abandon in the ink battleground, and obviously from the lush cultivation planets of the 3000 worlds. They are pretty bitter loot for Yang Kai. At least a thousand saved ink disciples is graceful.
Human array masters and refiners really should start to work on methods to convert ink force back into world force. It's strange that after more than a hundred thousand years of fighting, they haven't tried to do it.
