There's an Old Monster Living in My Body

(Multiple worlds + multi-races + no system + semi-invincible + relations + priesthood) Among the ten worlds, Fangliang was born in a law enforcement family in the first world. Not long after he was born, his family was destroyed. Queen Asra, the leader of the first world, adopted him in the name of her eldest sister and raised him as an adult. "There is an old monster living in my body!" "We bastards, let me live a good life!" The six of them started a family, and now they can no longer live in the house.
