After Transmigrating into a Book, I Accidentally Won the Heart of the Miaojiang Youth

Chu He transmigrated into a novel.
[That villain will kill the male lead, cripple the female lead, and eventually end his own life in despair. This world is on the verge of collapse, and your task is to save it.]
The useless system dumped the mission and vanished before Chu He could even figure out what to do. To make matters worse, she was kidnapped to Miaojiang and became the perfect vessel for the poison masters to cultivate their Gu.
Poison vessels were not human—they remembered nothing of their past.
The mother Gu was precious, and only the last survivor of the bloody struggle had the right to claim her.
Moments later, the ground was littered with corpses.
A white-haired youth in bloodstained robes stepped forward, his path lined with venomous Gu insects watching hungrily.
Chu He clenched her teeth and blurted out a lie: “You can’t kill me—I’m already carrying your child!”
The youth paused, tilting his head slightly.
Half a year later, the system finally reconnected and resumed its explanation.
[Listen up, the reason that villain is so insane and twisted is because he was raised as a poison vessel, fed on Gu toxins since childhood. He lacks normal human emotions, and he—]
“Is obsessive and relentless, never stopping until he gets what he wants.”
The system hesitated. [How did you know that?]
Chu He lay weakly on the bed, her voice drained of hope. “It all goes back to the day I spoke without thinking…”
The door creaked open, letting in a sliver of light.
The youth approached with the soft chime of silver ornaments, bending down until his crimson eyes locked onto her face. His whisper was tender yet chilling. “Ah He, today is another day for us to work hard… to bring Little Treasure into the world.”
The system: [Who is Little Treasure?]
Chu He huddled in the corner, clutching the blankets as chains rattled nearby. She wanted to cry but had no tears left.
—Of course, it was the child she owed him!
