Just like that, the ugly-looking and muscular Dragon Elf King was tamed with the addition of a True Dragon Fruit tree and a tray of True Dragon Fruits. Gao Peng felt that even if he were to leave this secret border now, he could still consider this a respectable profit.
Based on Gao Peng's estimations, even if the True Dragon Fruit was considered a treasure in the dragon's ancestral lands, it wasn't really that precious, since it had no effect on dragon monsters above the Mythical or Legendary grades. However, having a True Dragon Fruit tree meant an endless supply of True Dragon Fruits, meaning that it could continuously help produce excellent monsters for a force.
Moreover, familiars and monster trainers that had their grades evolved after being given such rewards were usually more loyal. Perhaps it was because they knew that strength and power didn't come easily and were thus more appreciative of the opportunity for evolution.
