Review Detail of in My Vampire System

Overall very mediocre. My biggest complaint is the novel taking 334 chapters for the MC to finally start showing his strength. I've always hated novels where the character has to constantly keep his power hidden. In the entire 334 chapters available the MC has only been able to show his true power/go all out 2 times. Pairing that with the constant perspective switching just destroys the pacing of the novel and makes it annoying to read. The lore/world is very cool but the incredibly slow pacing makes me feel like this novel won't be worth reading/returning to until there are at least 700+ chapters because after reading everything available so far I'm only left thinking how boring it was.
