After Winning Over the Sickly-Yandere Villain, I Ran Away Pregnant

Xin Sui transmigrates into an apocalyptic novel as a disposable character who doesn't survive past the first chapter. From the start, she's in hell mode.

The System also orders her to bring the final villain's corruption level down to zero and stop him from destroying the world.

To complete her mission and earn a reborn reward, Xin Sui follows the System's instructions: she feeds the villain, lulls him to sleep, sings to him, and pets him to keep him calm.

The day she finally gets his corruption level down to zero, Xin Sui turns around and kills him.

The System is stunned. "You actually killed the final villain!"

"If he's dead, he can't destroy the world anymore. Doesn't that mean I completed the mission?"

The System: "...But the final villain isn't dead."

Not only is the villain alive, he breaks through his limits in the depths of despair and becomes the strongest person in the apocalypse.

Xin Sui turns and runs without a word, but what she never expected was...

By then, she was already carrying a little one in her belly...
