(Book one complete!) Rise of the Blood God [Vampire Isekai LitRPG]

All Darian ever wanted to do was help people—But then he died. His cancer robbed him of everything. Friends, adventure, and now even his life. But as he breathes his last breath, his wish for a stronger body is answered. Darian is reborn and remade—transported in death to a world of magic, monsters, and gods. Waking alone in a haunted forest, he quickly finds himself in the middle of a war between the living and the dead. Fighting to retain his slipping humanity, Darian must battle the undead hordes if he hopes to survive. But his new body thirsts, and he soon realizes his wish wasn't granted without a price. And lurking in the darkness are forces that would use Darian, for he is on a path to divine power, even if he doesn’t know it yet. What to expect: Slow level progression. No overpowered start (MC is NOT weak, just not OP). MC that struggles with his new life as a vampire. Group battles and a small bit of party building.  Lots of action Chapter length: 1500-2500 words.
