I Transmigrated into a Nobody, Yet I Can Still Crush You

He Xi transmigrates, but into the body of a good-for-nothing who can't beat anyone and can only play with mud. Just as she's getting frustrated, she realizes she can mold the arena like clay.

The audience: We've seen people with real strength, but never anyone who knows how to have this much fun.
