Quick Transmigration: This Villain Has Issues

The system panics: "Warning! The neighbor is a villain who harasses our host daily!" Ning San'er just shrugs. "Yeah, I know." When a suspiciously cheerful voice calls from outside—"Xiao San'er, I came to see you! Aren't you happy?"—she calmly pulls out a baseball bat. System: "Didn't you say you weren't violent?" Ning San'er: "Who said that?" Armed with maximum combat power and zero patience, Ning San'er travels through worlds dealing with problematic villains in her own unique way. Too bad the sharpest-tongued villain of all might just be the one she can't beat into submission.
