Upon understanding the use of Eternal Points, Draco and Eva lost interest in working hard. See, the obviously smart choice would be to keep their various points on hand and training themselves till they reach their limit, then apply the points when there was no more organic progress to be made.
However, they had already wasted over a month here and they had people waiting for them out there, especially their newborn daughter Lucitera. Just because the little tot was busy sucking up origin energy as sustenance didn't mean that she would do that forever.
If she suddenly stopped and looked for her parents, only to find that they were away, how would the little baby feel?
Besides, Draco and Eva were used to rapidly gaining strength and power, how could they settle for grinding over time? Yeah, all that talk about 24 years was logical and touching, but ain't nobody got time for dat!
