Breeders had devised ways to combine various materials to create energy cubes that was containing life energy for them to absorb.
These types of energy cubes were extremely valuable and usually not openly priced on the market.
Although the cost of producing them based on a specific formula was similar, if it is as sold publicly, the black energy cubes for Little Cosmicub would be much more expensive than the red ones for Sparky.
After feeding the expensive energy cubes to Sparky and Little Cosmicub, Riley didn't waste any time and quickly got them started on their training.
The active energy effect didn't last 24 hours; once the energy cubes were digested, the effect would be gone.
Sparky was always eager to train, and after the recent mission, Little Cosmicub's attitude towards training had also changed.
Both of them enthusiastically turned to their training.
