One day, Chu Congmo, the young lord of a palace in the Ninth Heaven, suddenly gained a set of memories. In them, a man named Li Yuan, who had once done odd jobs in the Ninth Heaven, was cast down from the highest heaven to the lowest, the First Heaven. Then he began his overpowered journey, fighting his way back up to the Ninth Heaven and taking the supreme throne. A classic revenge-and-comeback power fantasy.
Let's set aside the question of how he ended up with the throne of the Ninth Heaven. Why should his demotion to the lower realm drag his little sister into it?! Chu Leqing, his precious little sister whom he cherished so much he feared she might break if he held her too tightly or melt if he held her in his mouth, would have to endure all kinds of hardship because of that man. Losing her memory and getting injured would be the least of it. She'd also have to deal with all of that man's awful admirers.
Seeing his sister heartbroken and suffering, Chu Congmo burned with rage. He would deal with this man right now, before he had even the slightest chance to get near his precious little sister.
But...
Gazing up at the blue sky of the First Heaven, Chu Congmo held his unconscious sister and angrily kicked Li Yuan, who was lying on the ground. A hundred ways to kill this bastard who'd dragged both his sister and him into trouble flashed through his mind.
At first
Chu Congmo: You are not allowed to breathe within ten zhang of Qingqing! (▼ヘ▼#)
Li Yuan, who had never met Chu Leqing: Who's Qingqing?
A while later
Chu Congmo: Bro, I guess I wouldn't be against you becoming my brother-in-law. (* ̄︶ ̄)
Li Yuan, thinking about pulling Chu Congmo into his arms: Why would I be your brother-in-law? Shouldn't I be...
Later
Li Yuan, kissing the person in his arms: Congmo, you don't have to worry about me going after your sister anymore, right?
Chu Congmo, who'd been ravaged all night: Get lost! (T▽T)
