I believe the undead disappear unless they were made from corpses. But based on Vol 8 he doesn't need a whole corpse as he made a Death Knight from just a head. The first 70,000 killed in Vol 9 were used to summon the Dark Young, but I don't think that was permanent. There were at least several tens of thousands killed by the Dark Young but there was no mention that Nazarick collected the corpses. There are also other uses for corpses. I believe Demiurge was succesful in using human skin (from Sunlight Scripture members?) as parchment for scrolls.
