Yu Ruotang transmigrated into a book, becoming a cannon-fodder junior disciple in the Hehuan Sect.
In the original story, the junior disciple encounters the severely injured Demon Lord, whose cultivation has been temporarily sealed, in a minor secret realm. Boldly, she gives him a certain drug. After spending one night together, the Demon Lord regains his cultivation and cuts her to pieces. She dies a gruesome death.
When Yu Ruotang transmigrates, she's holding a bottle of medicine, and the Demon Lord before her is just waking up from a coma.
Bad news: she's already given him the medicine.
Good news: they haven't slept together yet.
A clever idea strikes her, and she rushes to make amends. "I've got lots of pills here. I don't know which ones will help your injuries, so why don't you take them all!"
Pretending to treat the Demon Lord, she feeds him every medicine in her storage pouch, then folds her hands and prays devoutly that something will happen to him.
Then she discovers, to her despair, that escaping the secret realm requires breaking through sixty-four formations, and she knows nothing about formations.
The original story never mentioned this!
Help, she just fed the Demon Lord a pile of random medicine!
*
Yu Ruotang finds a manual on formations, but still ends up sleeping with the Demon Lord.
From then on, she works hard to study the manual and escape while being forced to care for the severely injured Demon Lord and help him deal with the unspeakable mixed drug she'd given him.
But she's clumsy. One day she accidentally lets the Demon Lord tumble into a spirit pool; the next, she makes him eat a poisonous herb. The Demon Lord bullies and threatens her every day.
She thinks she's definitely on the Demon Lord's kill list. The moment he regains his cultivation, he'll cut her to pieces!
One day, she discovers in horror that the Demon Lord is starting to recover his cultivation and can even use the simplest cleansing spell. Terrified, she pushes herself to the limit overnight, breaks through the formations, and runs off, hiking up her skirt.
The Demon Lord turns the secret realm upside down before he's forced to admit that his wife has run away.
*
They say the Demon Lord has recently been searching everywhere like a mad dog for an unknown female cultivator whose sect and name are a mystery.
She's beautiful and otherworldly, and her portrait has spread throughout the cultivation world.
Yu Ruotang: Help, the Demon Lord is hunting me down!
[Reading Notes]
1. The heroine is a soft, clumsy type. Please don't dislike her for being silly, okay? QvQ
2. The hero is a mad dog with an overwhelming possessive streak who searches everywhere for his wife.
3. Don't mention other authors' works in my comments, and especially don't mention my work in other authors' comments.
