You should definitely give mushoku tensei a try. It's probably the best adventure/ reincarnation novel out there.

If you're looking for something along the lines of sword art online, you can either read that or start reading Legendary Moonlight Sculptor or LMS for short. It's probably the most well known Korean light novel in this subreddit , besides Ark which, being a MMORPG novel, shares some similarities with LMS.

if you're looking for a very funny , yet sometimes serious "demon lord" sort of novel , then take a look at legend of the sun knight

If what you're looking for is more along the lines of "Xianxia" or "Wuxia" (Chinese martial arts and the pursuit of immortality) than you can have a look at I eat tomatoes works. He's a famous web novelist in China. Some of his works include stellar transformations , coiling dragon , swallowed star and his current one , desolate era

Or you might like Duolou Dalu

If you prefer "being summoned to another world" then you'll enjoy Problem children are coming from another world, aren't they?

I have a huge , HUGE list of light novels that you'll enjoy reading, not just the everyday stuff you'll see on this subreddit, which, at the moment, is just being spammed with chapter updates for 2-3 light novels every day. While I enjoy those light novels, it does get a bit tiring seeing nothing but cooling dragon and Zhan long on the front page at times. But I digress. If you want recommendations based on preferences that I have listed, just ask and I'll hook you up bro.
