[Brother-con, no female lead or one female lead, genius]
Su Xian'an learned to fend for himself at ten. His little sister disappeared, and his parents were gone.
At seventeen, he learned the truth and resolutely entered the world of cultivation.
He searches for his sister and storms the immortal sects. So what if they're immortals? He's here to beat up immortals!
After finding his sister, Su Xian'an's favorite things to say are: "Anyone who bullies my sister dies. Anyone who hurts my sister dies again and again."
After that, he keeps feeling like his sister's gaze is getting stranger and stranger.
Author: Tease my little sister, get Amaterasu'd.
(Cough, don't worry about the posting dates of the first two chapters. This is a new book, and it's not a story about looking after someone. If there's a female lead, it won't be his sister. The author doesn't want to get electrocuted!!!)
