[Funny + villain + evil + system + female protagonist]
Others who travel through time are either children of luck or awesome villains.
And I traveled through time and turned out to be a villain!
But once you accept this setting, you can't stop doing bad things.
"Kid, your candied haws look delicious, bring it to you!"
"Girl, your back is so beautiful. It would be a pity not to cup it."
"My dear friend, I have a bottle of purple (crazy) spirit (venting) pill here to help you improve your cultivation."
I'm either doing bad things or on the way to doing bad things.
But those who come out to fool around will have to pay back sooner or later, until that day...
