I'm the BOSS in Castlevania

I am Dracula, and I am also a non-prisoner. I was originally an ordinary and hard-working migrant worker. Unexpectedly, I was accidentally reincarnated into a different world. As a result, on the first day after I woke up, I was ridiculed by the seven angels and the Supreme Will. Doesn't this world have any warmth for non-prisoners? However, fate finally allowed me to survive. Who saved me? What's the conspiracy behind this? This novel and its characters are purely fictitious.
