Noah had initially decided to take the slow approach and to perfect his cultivation technique by forging an inscribed item in the fourth rank that he would then put inside his dantian.
Yet, there were too many problems to solve in that approach, the first of them was that Noah was still unable to forge a rank 4 item.
Also, the items that he had managed to forge grew without restraint, their form absorbed "Breath" that further fueled the vortex that they generated, something that unstable couldn't be put inside a center of power.
It was only after the new continent fell from the sky and he felt the urge to match the other heroic cultivators that he understood that the blueprint for the Black hole cultivation technique was wrong and that he had to modify it.
'If I render the condensed "Breath" blessing able to absorb "Breath", then it will even absorb that in my dantian once I put it inside it, there is no fix to this issue. The "black hole" can't be a sphere, it must be a hole.'
