It's really boring. It skips over a bunch of content and doesn't really have any depth.
Showed potential but after mc was being (Warning slight spoiler next:)forced into a spirit contract they started skipping content which caused this series major damage... Also can't say for sure if it's for the whole series but seems the mc is a no-kill btch mc (no humans being killed by mc no matter how evil...) they let others handle the killing of them like mobs or other evil humans... honestly it's really a shame because I really like series with mc's being reborn as a monsters and they can evolve... mc also is quite the idiot which is doing quite a number on this series aswell, dunno if this series is worth it and with all those paywalls it will be a while before I ever check if it truly is or not...
