Review Detail of Prosperous in Kael Cor: A Vampire's Awakening

So first off, not my cup of tea so take what I say with a grain of salt... To avoid spoilers, lets just say that this story is missing some tags. Like "Tragedy", "Blackmail", "Betrayal", "Slavery", "Extortion", "Rape" and "Grimdark". Lots of trigger warnings needed. The summary made me think this was going to be a story where the MC gets a "system" or uses "game-like elements" to quickly become OP and face slap the people who made him a vampire and enslaved him but that is not what happens... at least not in the first 50 chapters. I tried to give the story a fair shot; the author himself admits the first 4 chapters are not great and that this is a repost of his first ever story but I got to 50 chapters and had to quit. Its hard to give examples without spoilers but any one of my suggested tags would have been a deal breaker for me normally so I cant reccomend this story. P.S. The MC is also reborn from modern Earth so he makes a lot of references but since the setting is a fantasy world it feels real jarring and destroys any chance of immersion. Usually I dont mind if the reincarnated MC invents pizza or makes an anime joke but in this dark fanatsy setting it feels awkward.
