I spent hours training with my mana, Velvet got exhausted in the first 30 minutes since she had no more mana left, so a big part of the training was her telling me what to do. It turns out doing that trick of hers really drains a lot of mana at once.
Which obviously makes the prolonged training more difficult, but after hours I replicated it perfectly. Of course, merely making others feel pleasure is useless, so later I'll have to train more on that and learn other things.
And as hours passed, I returned to the normal world. Of course, spending some time in my universe made me notice a few things, like the fact that the damn Lilith is biting the core of the universe in the castle.
It's not really Lilith, but her new head. It turns out Lilith likes to sleep in the treasure vault of my castle, and her new head ended up finding my core there and started biting it like a toy.
