Transported to Before the Demon King's Birth

Fang Sisi dies in an accidental car crash. As luck would have it, the transmigration System from a melodramatic novel really exists.

Fang Sisi: As long as I fix the novel and stop the Demon King from being born, I'll come back to life, right?

System: Yes, Host. We're a legitimate System. You can count on us.

Fang Sisi believes it, rolls up her sleeves, and gets to work, ready to embrace a wonderful tomorrow. But before she can make her mark, the System crashes. To keep itself running, it forcibly merges with a fantasy novel about immortals and demons.

Fang Sisi: So much for being reliable!

Not only has the plot been reduced to scraps, but where did this script about a tragic romance between an immortal and a demon come from? Weren't we supposed to dominate the cultivation world and sweep aside all opposition?

System: (trembling) It's all for the sake of keeping the novel running smoothly.

Fang Sisi: Even a donkey on the production team shouldn't be worked this hard. Let's just destroy the world.

System: Um, you can't go home if you don't finish the mission.

Fang Sisi: All right, boss. Tell me what happens next.

Carrying the plot of a tragic immortal-demon romance in her belly, Fang Sisi has no choice but to marry Lu Yichen. Hoping to restore the consciousness of her husband, whose mind is only six years old, Fang Sisi sets off with her whole family to follow the plot.

After several trials and tribulations, she completes the mission and safely returns to the real world. But who could have guessed that less than half a year later, the novel's world would collapse again?

Fang Sisi: Nobody told me I'd have to handle after-sales service too!

System: Um, your husband is the one who becomes the Demon King.

Theme: Love can overcome anything. May everyone find wonderful love, friendship, and family.
