Bound to the Wrong Childbearing System, I Took a Huge Loss

[Childbearing + System + Possessive + Yandere + Sweet Romance]

She was just a little rabbit spirit who had sneaked into the Celestial Court. She never expected to be caught by Lord Cangheng and made his personal divine beast. Why? To maintain the stability of the three thousand minor worlds, Lord Cangheng had to take her with him when he descended to the mortal realm. But she mistakenly bound herself to a childbearing System, and somehow became entangled with the Lord of every minor world.

This is bad, this is really bad... I've caused trouble...

Yet the Lord only smiled at her.
