At first it seemed like you were talking about "Mo Dao Zu Shi" but then you said rich elf and now I'm confused lol.
Lol I'm not even that sure if it was an elf or what. I've just got the memory of a goldfish Σ( ￣□￣||)
I remember this manga/hwa/hua of a guy (I think he was a warrior or something?) and he was killed in battle and he woke up in another body where there are supernatural things and I think a rich elf or something found him. Sorry for such a horrible description (￣∇￣")
