Kari looked at the young man and said affably, "Rock, I know you are the best student in this cohort, but you must not be careless. Although humans are livestock and kept in captivity, some are quite strong, after all, they are a special race.
We've had many cases here where these livestock managed to kill our people during initiation rituals. Of course, even if you are killed, we won't intervene. If you can't defeat these captive livestock, then you are not fit to become a noble servant of the Underworld; your status would be no different than these livestock, only suitable to become sacrifices!"
Although Kari was warning these students, his voice was still as pleasant as a spring breeze, convincing and soothing.
To become a qualified Meat-Winged Monster, one must learn to kill. Meat-Winged Monsters only aim for strength; in their eyes, only the strong survive, and those who are not strong enough are only fit to be sacrifices, even if they belong to their own race.
