I think was a Story here on RRL.

Story parts:
-Guy reborn/placed in a new world
-lands in a room with a old magus(?) who is dead ; He collects al the loot there
-then a vampire girl comes in and is trying late to make him her slave
-Girls party is a harem of an other otherworlder(dead)
-He later comes in a Dungeon city and buys a home and builds his own harem/party (?)




world settings:
-Dungeons
-vampires can "mark" a human
-later a dragon is Attacking/looking for the MC(?) here was the last chapter i read
 
How someone can think of something with this
