Having learned of the Demon Race's movements, Lin Ke knew he had to hurry his search for spirit insects.
His previous breeding attempts had all failed, producing only two kinds of spirit insects: Heart-Corroding Centipedes and Fire-Poison Spiders.
But both kinds were too low in quality. Neither could serve as a candidate for his newly formed Golden Core, so he had to find another way.
He had examined all the spirit insects in the Spirit Insect Cave, and there were no suitable choices left.
So for now, he would probably have to work with the spirit insects he already had.
