Chinese steampunk-esque era Isekai, with a world inspired by the Soulsborne/SCP /Lovecraftian series and a Cultivation system pulling from Tarot cards and The Witcher.
While that is quite the word salad, it pretty much sums up the majority of what makes the setting of Lord of the Mysteries. This is one of the most talked about Cultivation novels that rivals Reverend Insanity in discussions. and fandom love.
The setting is unique and you learn about the world and it's eldritch darkness along with the main character, Klein. The power system is interesting: "cultivators" advance by creating potions made out of monster parts, and have to learn to adapt it to their body. No matter how far one goes in power ranking, there's always a chance of losing control and becoming the monsters you've ingested.
This is also one of the first Chinese webnovels/novels I've read that actually feel like it was written by a professional. It's prose keeps you hooked and interested with barely a repeating phrase that so commonly plagues the genre. There aren't any of the typical cultivation tropes here, either, if that's a plus for you!
