What happens when a fanfic author with a habit of lying and scheming suddenly finds himself as a self insert during Duelist Kingdom?

Chaos, dear reader. Sweet, sweet chaos

Jiang Ning was the true heiress of the Huo Family, lost and living outside. After being brought back by her family, her birth parents didn't like her, her cold-faced brother despised her, and her twin brothers would tell her to get lost from the home at the drop of a hat.Waking up alone in the hospital, she was diagnosed by the doctor with a terminal illness, yet her own family was busy throwing a party for the fake heiress. Jiang Ning was furious!She kicked these so-called family members one by one, sending them all flying!If they didn't accept her, she didn't care for them either!......Jiang Ning participated in a rural countryside live stream variety show.Her haters caught wind and came to greet Jiang Ning's entire family in the barrage of messages.But what they found was:Day one: Shock! Jiang Ning catches a thief on the street! A golden retriever runs over to help her.Day two: Jiang Ning snatches a child back from human traffickers with her bare hands! A bird publicly defecates on the traffickers' heads!Day three: Jiang Ning fights a criminal in a life-and-death struggle! A goose mocks them at the scene.Thief: “I had already finished stealing, and she still caught me. It's absurd.”Murderer on the run for sixteen years: “You might not believe it, but I just came to buy a bottle of water, and she came up to me with a big right hook.”A nice countryside live stream somehow turned into a legal synergy.The online audience crazily tagged the official police accounts:“Let's be honest, isn't she an undercover agent you dispatched?”“Jiang Ning's side job is entering the entertainment industry, but her main role is catching criminals, right?”A certain big shot attached a wedding photo: “Wife, mine.”
