Fantasy: I Specialize in Devouring the Cultivation of Big Men

[No system + easy + time travel] Xu Jiu traveled to a five-year-old child in a fantasy world. Aroused the ability to devour cultivation. On the third day after wearing it, two lives were lost. Except for the ability to devour cultivation, everything else is useless. Then just devour the cultivation of the big boss and survive until you become a big boss. "Dad, does this boss want to swallow him up? He's so arrogant." "Swallow it, he is your father's father." "What about this, can you swallow it?" "It goes against the harmony of nature to devour a person who is just passing by." "What's the use of this superpower? It's a waste of emotions!" "Boy, your dad is about to be reduced to ashes. Why don't you swallow it and keep it for the New Year?" "Oh, it's coming, right now!"
