The Villain's Daughter-In-Law Is a Power Player

The Villain's Daughter-In-Law Is a Power Player

I was possessed by a 19+, filthy, filthy, mermaid reverse harem novel. But not a mermaid, but a tree raised by a noblewoman? ...After that, I possessed salt shakers, jellyfish, canaries, etc., and finally succeeded in possessing a raccoon mermaid after the 17th possession!!! But this time, it wasn't easy either. A chimney sweeping extra, a spy of the Holy Kingdom who would die if caught, and the worst of all was... an albino who couldn't transform into a mermaid. Just die...! Just when I was thinking about starting over, "Won't you be my daughter-in-law?" The greatest villain in the world made me a daughter-in-law offer. Will I be able to survive as a daughter-in-law in this bloodless villain family?!
