After returning from God's Domain, Alex began focusing almost all of his time on one of two things. He was either helping Momo with her alchemy lessons, or he was busy improving the two Provenance Duality techniques.
Everything else was something for him to do when he was bored, which included his Blood Origin.
It was clear that he was going to need a lot of time to improve his regular Origin, so there was no point in rushing into Blood Origin at all. It was already coming along pretty well anyway.
Momo's alchemy training was back in full force from what Alex had left her an entire decade ago. Her knowledge had improved from her self-training, but there were many important things that training alone wouldn't help her with.
There was a list of things Alex needed to help Momo with, even before helping her with alchemy. She needed an upgrade to her abilities at a fundamental level.
It was time to help improve her spiritual roots.
