My Big Brother is Seeking Death Again Novel

In the cultivation realm, Yu Hua—the mightiest warrior—appointed Chi Hou to pursue intense cultivation. After relentless practice, Chi Hou became an unrivaled force for hundreds of thousands of years. The Demon Lord, however, never tired of mocking him: a hopelessly single bachelor, ancient as fossil bone, without a girlfriend or even a little sister to his name. Determined to end these jabs, Chi Hou hatched an audacious plan—kidnap the Demon Lord's beloved sister and raise her as his own. His approach was thorough: rescue her, nurture her carefully, instruct her in magic, prepare her meals, spin bedtime tales, and lavish her with precious treasures. Through devoted care, he'd become the quintessential brother, one she'd never forget—or rather, one whose presence would overshadow her true sibling. Yet his newly acquired sister had other thoughts: "Why does this lunatic drag me out every night for ghost stories? Reaching celestial levels is exhausting. I want to return to Earth!" She remained decidedly unimpressed by his efforts.
