[Both reborn + transmigrate into a book + System + stunningly beautiful heroine + no substitute trope + male lead is a yandere]
Moon Goddess Yeluo × Demon Lord Ye Zhuoyu
Yeluo transmigrates into a book as an idiotic villainess demon who keeps giving the protagonist's team experience and equipment. Even her own parents weren't this hardworking! Then she gets betrayed, mobbed, and stabbed full of holes, meeting a gruesome end.
Reborn in a new life, she learns from her mistakes and takes a different path. Let's go crazy together, have a blast together, and run headfirst into a wall together!
Punch the Wuji Sect's retirement home and kick down the Wanxian Sect's kindergarten!!!
With a treasured artifact in hand, she's bloodthirsty and ruthless. Since they call her a demoness, she'll live up to the name. Summoning arts? She'll learn them. Top-grade spirit treasures? Hand them over. Heir to the Moon Goddess? She might consider it.
In her everyday life, she teaches the junior brother from the neighboring sect to dance the flower-shaking dance and ascend to heaven, aggressively promotes local specialties to her fellow disciples, lifts the roof for some fresh air, and occasionally takes her sectmates to dance on her sworn enemy's grave. And with that, another beautiful day has passed.
There's a saying in the sect: When things are dangerous, Senior Sister is the safest person around. When things are safest, Senior Sister is the most dangerous of all.
At a sect ceremony, someone asks why Senior Sister is so messed up.
She knows this one! Yeluo grabs the microphone and eagerly speaks, addressing the new disciples earnestly: “The road ends at the edge of the world; talk too much and you'll get killed. You handle the slaughter, I'll handle the cackling.”
At the Demon-Slaying Assembly, Yeluo keeps her hands in her pockets and beats the people who mobbed her in her previous life until they don't dare look their opponents in the eye.
The Demon Lord rubs her shoulders and pounds her back. “Tired from fighting? Take a break.”
Mo Ce, the ghost god: “Sister, please pat my head!”
The Western Regions' prince kicks him aside. “Mommy's mine. Get lost!”
I like it😍The heroine is really funny
