After Breaking Off My Engagement, I Became the Cultivation World's White Moonlight by Playing the Villain

Transmigrated as the brainless female supporting character in a xianxia novel, she’s about to be hacked to death by the protagonist’s group from the start?

Lin Youyou: Don’t panic, I have a Villain System! As long as I keep doing evil, I can grow stronger and stay alive!

System mission: [Humiliate the heroine in public and shatter her Dao heart!]

Lin Youyou, causing trouble like crazy: “You stole my elixir! This is the most deadly poison in the world!”

Three seconds later, the heroine breaks through on the spot, tears streaming down her face. “Senior Sister Lin, you used such a precious divine elixir to temper my character… I can never repay your kindness…”

System: [Ding!

Plot disruption maxed out!

Karma +9999!

Reward: The Immortal King’s Inheritance!]

Lin Youyou: “???”

Later…

She snatches a fortuitous opportunity, and it automatically upgrades. She sets a trap, and it turns into a blessed land. She defects to the Demon Realm, and its GDP doubles overnight…

The whole world sings her praises for her “far-sighted plans.” Even the Demon Venerable, who’s set on destroying the world, pins her against the wall. “Woman, you’ve successfully caught my attention.”

Clutching countless divine artifacts and mountains of merit, Lin Youyou wails at the System: “Please! Just let me be a real villain for once!”

System: [Sorry, according to our assessment, you are already the most successful “villain” of the century.]
