From now on, Lin Yuan would need to supply food to Red Thorn as he did for Genius and Chimey.
Lin Yuan had already come to a decision about Red Thorn food supply. What else could be more suitable than the alien insects as a food source for Red Thorn?
The alien insects had hard shells, while their flesh had corrosive properties.
If these alien insects were used to feed Red Thorn, they would increase Red Thorn's digestive ability and allow Red Thorn's predator organs to produce a potent corrosive fluid in order to digest them.
The alien insects were products of the dimensional rift and insect world. They weren't available in this world.
On the Star Web, the carcasses of alien insects were sold as spiritual ingredients. Lin Yuan immediately went to purchase insect carcasses for Red Thorn to see how many of them it had to digest before reaching normal-grade.
