Cut It Out! The Useless Ninth Young Lady Kidnapped the Demon Emperor?

"Drunk, I knew not the sky above the water; in my boat, clear dreams pressed down upon the River of Stars."

Xiao Qingmeng, the modern world's top assassin, transmigrates into the body of the infamous good-for-nothing Ninth Miss on the Cloudsky Continent. She possesses an unawakened Chaos Spiritual Root. Though she seems weak and easy to bully, she is actually a family treasure, cherished and adored by all. Only when her Spirit Spring Space awakens does she truly begin to reveal her edge: cultivating, taming beasts, refining pills... she masters every art.

The Devil Emperor Yue Xinghe has ruled the Demon Realm for three thousand years. Cold and bloodthirsty, he falls completely for her after one breathtaking glance. To get close to her, he even disguises himself as a badly injured, scheming pretty boy, acting innocent and playing the victim before her, carefully laying his plans so he can claim her as his own.

She devotes herself to her ambitions, leaving no loose ends and climbing ever higher. He insists on romance, loving her with single-minded intensity and protecting her with an iron grip. When the good-for-nothing young lady bares her claws and the Devil Emperor casts aside his disguise, they stand side by side, ruling the Three Realms and writing an against-the-heavens legend of equals, full of sweet romance and free of angst.
