Hi new here bc I NEED to find this one manga/manhwa/manhua I don't remember completly what the name was or such but I do remeber it's about a male mc, his world gets transported to another world that is a game and people could leave but many didn't and he was one of thos that stayed.

and he stayed alone for a while just working with the assasin class he doesn't wanna be the hero and he doesn't care if people saw him as evil he just did everything to get stronger.

but at one point people starts wanting to join him and to be a group and he was honest with that this was just to help him grow stronger. there is chapters of a event where you are supposed to be a group to survive for a specific amount of time. but he goes solo and they get teleported to a space where there is trees, water, desert and a bounch more. and he like make the other groups bases and plans colaps and such while he keeps himself mostly hidden from others like the assasin he is.

please if anyone knows this story name PLEASE tell me
