Roy’s life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.
…
It’s really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??
Join Roy as he ventures through various worlds with the Custom Made Demon King System—a system that allows Roy to draw anything he can imagine and create it through exchanging souls!

Qiu Qiu was born into a scholarly family. He possessed great looks and a kind heart. His outstanding grades were just as praiseworthy as the cute dimple he exposed each time he laughed. His melodic singing moved the hearts of all, and his guitar-playing skills were down-right godly. It wasn’t long before the overbearing president, Fu Ruien, fell for him, hard.

Fu Ruien: Qiuqiu, I would like to ‘support’ you.

Qiu Qiu: Oh, so you’re going to support me financially?! Like a scholarship?! Yay, that’s great!

And so, the two happily made arrangements, utterly oblivious to the fact that they both weren’t on the same page…

…..Three months later.

Fu Ruien: Are you a numbskull?! If you’re not being ‘kept’ by me, then why the hell would you call me ‘Daddy’?!

Qiu Qiu: In my defense, I saw that you were a 40-year-old uncle who still hadn’t been married, so I just wanted you to actually experience the warmth of a family!

Fu Ruien: …???

Qiu Qiu: But even if you don’t have a partner, at least you have this bright, talented and handsome eldest son who’s there for you. I mean, just where in the world would you be able to find such a perfect son like him!

“He” was originally a weak and pitiful “sissy”. Once reborn, he became an ancient martial arts genius with both medicine and poison. The national male god.

Don’t touch anyone who belongs to her, and she will hold what is not her, and she will never be merciless when she abuses scum and face.

He is a business genius who covers the sky with one hand in Huaguo. He has a dark belly and is decisive in killing. He is the only one who turns into a loyal dog in front of her.

She kills, he sets fire. She poisoned, he silenced.

One day, the pampered and lawless Lu Xingchen said in disgust, “Brother, they all say you are my dog.”
