I Got Reincarnated as a Weed

After arriving in another world, he became a weed growing in front of a powerful cultivator's home, getting stepped on whenever the man felt like it.

The System activated, and he got a cheat ability to back him up.

He had to teach this big shot some manners: you can't just step on grass whenever you feel like it.

P.S. The title and blurb are utterly unremarkable. I've given up trying to fix them.
