The Heavenly Emperor's Wonderful Life in Another World

I am a Heavenly Emperor. One night, I inexplicably transmigrated to another world and, in a cliché turn of events, ended up living with a Blood Princess. She might even be an ancestor?

“Lowly human, hurry up and offer Me your sweet blood... Wait, y-you, what are you doing to Me...? No... Don’t... Not there... I was wrong~”

This is the story of a Blood Clan progenitor and a shameless Heavenly Emperor in another world.
