Don't Think Too Much About It

Two weeks go by in the purple world before the fifth day in the normal world after Lucien meets Claire and Saira.

He spends half his time focused on strengthening his wives, but since there are only four of them, not counting Lust, with him now, the girls end up getting exhausted and full of demonic pretty quickly, considering the long love sessions he had with all his wives together.

Oya advanced to the fifth layer of the Earth Realm and Helena to the fifth layer of the Immortal Realm as she was a long time in the peak of the fourth one. 

Yet, Mira and Kamala remain in the eighth layer of the Immortal Realm as advancing in such a stage requires a lot of time and demonic energy.

Lucien also took a lot of time to advance a layer because even though he was in the Earth Realm, he received less benefit from being with a few wives, while those few ones received a lot from having all his attention just for them.
