novel link please 🙏 also manhwa reccs with such deep world building

I'm planning to read the light novel too and this is what I've found:

https://novelight.net/book/surviving-the-game-as-a-barbarian

Also, I don't know if I get the titles right, but I recommend "Solo Necromancy", "Solo Farming in the Tower", and "Skeleton Soldier".
I also think "On My Way to meet Mom". Though it's short, the world building is intriguing and seems kinda deep.

Well i hope you'd like this one
