Even though Raymond praise the quality of the people coming out of the Untainted Land, there is an inherent advantage of people who live in this side of the world
If the advantage of the people of the Untainted Land is time, then the advantage of the people living in the real world is none other than energy.
Boundless energy generated by the All Source. It could even afford five Divine Comprehension leveler and an Essence Creation leveler
Some worlds would already exhausts all of their energy and would take tens of hound of years to replenish back the energy that is lost to support even one Essence Creation leveler.
The reason why the Untainted Land is limited only to Disk Formation and the max which is Divine Comprehension is because that world could not withstand the levelling up of a Divine Comprehension realm.
