Brain-off fun + hilarious absurdity + trope subversion + wild imagination. An ancient young general suddenly lands in a little convenience store, trading antiques with a snarky woman for supplies.
"Good heavens! That jade is so green, it's a thousand times greener than my ex-boyfriend's face. Pay me enough, and I'll feed any number of people!"
She lends a hand and gets mistaken for a goddess, then casually flirts with him: "With a face as handsome as yours, I'd do more than help you. I'd even pay you for the privilege."
A domineering CEO buys antiques to get revenge? She turns around and sells them as junk, bringing him to the brink of bankruptcy. Their scandalous affair makes the headlines: "Won't you let me come up and sit for a while?" "Maybe in your next life."
She visits the ancient world and hears that the enemy kingdom's God of War is monstrously strong. One kiss turns him into a loyal, lovesick puppy: "I was wrong! I must've been kicked in the head to kiss you. Please, just let me go!" The God of War replies: "I can kiss you too."
There's no way I'm marrying an ancient man. I can marry into your family instead. The enemy king, the God of War, and the young general all fight over her in public, but she just wants to focus on stirring things up.
The emperor of her own kingdom is incompetent and talks too much? She flies him to the modern world by helicopter and turns him into an immortal. The great general takes the throne by force, but modern technology leaves him hopelessly outclassed. The one thing she can't change is his habit of picking wildflowers: "Go on, leave. Even if you travel to the ends of the earth, you can't escape my heart. Once you've gone, I'll leave too. Even if I travel to the ends of the earth, I can't escape how deeply you're in my heart." Her family all agree: "She's reached a whole new level of shamelessness!"
Note: The main plot's golden finger is fairly low-key. The side plots provide half the laughs: the people who stir things up are hilarious, and the funny ones have no interest in causing trouble.
