I, Luo Hou, the Demon Ancestor, Became the School Beauty Empress's Spirit Beast

I'm a transmigrator from Earth who fused with the incomplete source of Rahu, defeated in the battle between Dao and Demons in the primordial mythology. I became the new Demon Ancestor, Rahu, and triggered the transmigration mechanism after being struck by the Heavenly Dao.

I was reborn as the bonded spirit beast of Fang Lingran, a stunningly beautiful campus belle.

To make her submit to me and become my personal maid, I set out on a whole series of schemes to raise and groom her through shameless deception!

My name is Fang Lingran. I've realized my bonded spirit beast isn't quite right in the head. It keeps trying to talk me into killing people, and even wants me to be its maid. What should I do? Please answer ASAP!

Years later, after Rahu has raised her, Fang Lingran looks back and realizes that she has somehow fought her way to becoming the supreme empress.
