I was born a god, the son of the Demon Lord.

The score just came out, it'll go up!!!
[Female lead, no romantic partner + family + satisfying read + doted on by the group + don't overthink it + not a serious story!]
Xu Nanyi died because she cursed the author.
She transmigrated into the body of the daughter of a villainous female supporting character who died young in a melodramatic fantasy novel.
Good news: She has a system.
Better news: She and the system decided to try having the cold and aloof demon father from the original story carry two eggs!
But after the Demon Father was parasitized... why was my brother also reborn?!
Brother: This time I'm going to save my sister! (He desperately wants to be the older brother)
Sister Tongzi also took on a side job, binding her younger brother to a "Sister-Supporting System".
Xu Nanyi: What?! My brother does the task, and I get half the reward!
【small theater】
Father: Daughter, don't eat worms, they'll cause malnutrition and stunt your growth.
The son who was mistaken for a worm: I am a dragon!
Demon Father: Deaf... not quite suitable to inherit my position as Demon Lord.
Demon Queen Mother: You're overthinking it. Your daughter is destined to inherit the Demon Queen's position. Don't even think about it if you're not cut out for it.
Demon Father: Aaaaah! I'm not a concubine in your harem! Once I lay my egg, I'll raze your demon realm to the ground!
Xu Nanyi swallowed hard.
Father, why don't you take a look at the chains on your hands first?
1. The female protagonist is a phoenix, her younger brother is a dragon, and the demon race is a matriarchal clan.
2. This is a ridiculously funny story; if you don't laugh yourself to death, the insurance company will be happy.
