Transmigrated Villain: I Turned the Female Lead Into a Yandere!

Gu Chengxing transmigrates into the world of a female-centric fantasy novel and becomes the biggest villain in the book!

Recalling the terrifying talent and ruthless methods of the protagonist Shen Ruochu in the original novel, Gu Chengxing felt that he was about to be doomed.

However, the good news is that he traveled back 10 years to the time when the main story begins, which happens to be the day Gu Chengxing killed the protagonist Shen Ruochu's entire family.

The bad news is that when he transmigrated, he had already killed Shen Ruochu's entire family, and the protagonist, Shen Ruochu, was about to return and witness this bloody scene.

Just as Gu Chengxing was thinking about running away, a clear, mechanical voice suddenly reached his ears.

[Ding! The host has slaughtered the entire Shen family and unexpectedly encountered the destined heroine, Shen Ruochu, triggering a villain selection!]

[Option 1: Sneak away, pretending you were never here. Reward: Your Demonic Body erupts, greatly increasing your strength, and you lose your sanity, becoming a puppet of demonic desire.]

[Option Two: Follow the plot development without making any changes, and wait to seize the future. You will receive the title 'Hidden Turtle,' automatically gaining the ability to hide in the turtle and never leave the turtle!]

[Option 3: Proactively reveal yourself to Shen Ruochu, the Chosen One, and inform her that you are the one who massacred her family, then take her under your wing. Reward: The hidden dangers of the Heavenly Demon Body are completely resolved, eliminating the risk of its recurrence.]

After much deliberation, the time traveler Gu Chengxing finally chose to appear before Shen Ruochu and take her with him.

I've kept it by my side for over ten years in an extremely peculiar way.
