Who Says My Awakened Ability Is Useless?

Shen Yuan accidentally transmigrates to a world three hundred years after strange beasts invaded. During his graduation awakening exam, he awakens a Primordial-grade devouring ability. The next moment, jealous Heaven strikes him with lightning, unexpectedly activating the Godslayer System. Starting with the hunt for his first strange beast, he devours everything that gets in his way. Beast General? I’ll drain you dry! Beast King? I’ll have you for a light meal. What? There’s a Beast God? You’re nothing but nourishment to me.
