My World I Am the King

I was born in a world that seemed peaceful but was overrun with monsters, martial arts were on the rise, and supernatural powers were flourishing. I just want to live an ordinary life, but don't touch my bottom line. If you offend me even a little, I will slaughter your whole family. Don't touch what I want to protect, because if you touch it, you will die. If someone offends me, I will pay him back a thousand times. If a demon offends me, I will kill all the demons. If the world is against me, I will break it. Create my world and let me be the king. This novel and its characters are purely fictitious.
