Excerpt:

Holding his drunk wife in his arms, Andrew kicked the bedroom door open.

When he placed her in the bed, Rachael slowly opened her eyes. “Are we home?”

“Yes.” Taking her heels off, he covered her with the quilt. “I'll get you some warm water.” But before he could get up, she grabbed his hand.

“What happened? Do you want something else?”

Kicking the quilt off, she crawled in his lap. Placing one hand on his cheek and the other at the back of his neck, she inched closer. “Andrew—”

“Hmm?”

“I think I am falling for you, what should I do?”

The strongest man of the cultivation world, Yu Hua had sent the Grand Supreme Elderly Lord, Chi Hou to cultivate. After cultivating, Chi Hou was unrivaled for hundreds of thousands of years. However, he was ridiculed by the Demon Lord to be a bachelor who is as old as bone ashes and a fossil grade single dog. Not to even mention a girl, he doesn’t even have a little sister. In order to reverse the game, Chi Hou decided to kidnap the Demon Lord’s precious sister and turn her into his own little sister. He’ll first save her, then raise her, teach her magic, feed her dinner, tell her bedtime stories, and give her rare treasures. Like this, he’ll be the perfect brother. She won’t even remember her real brother.

Little sister: “What does this pervert who pulls me up every night to tell me ghost stories want to do? Cultivating to become a celestial is too hard, I want to go back to Earth!”
