Awakened Ability: Isn't This a Parasite Seed?

[Superpowers + rise of the wood element + offense and support + invincible in the later stages + no heroine + a slightly slow start]

(This is my first novel, and it's not very well written, so I don't really recommend it. I'm only continuing because I want to finish it.)

“Wait... isn't this thing a parasitic seed?! Have I turned into a garlic turtle?” On the surface, he's a gentle, harmless wood-element support. In reality, he's a tyrant who steals life force! His opponents wither in terror, entangled in thorns, while his teammates thrive under a shower of green light. Lin Feng gazes at his “harmless” wood-element power and falls into thought. Other people level up through hard training; he does it by sucking, sucking, and sucking! Other people need luck to learn skills; he just steals talents! Much later... “What Life Sovereign? I'm just a little support.”
