Benjamin never cared about energy as he had unlimited amount of aura. When a person has intent about level 20, they are able to corrupt matter into energy. For every increase in level of intent, the control over the energy is increased by ten times and the precision is also increased by ten times.
So even if he did not have unlimited aura, as long as he existed in the material world, he would be never be in short of energy. Such control had meant that if an intent lord wanted, he could keep learn about the structural arrangement of matter to convert one form of matter into another and for him, he could simply create matter.
He had read the records that a person with level 60 intent can indeed control the space and a person with level 100 intent can control time. This was easily known as the first person to come to this world was an intent lord with level 100.
Each level difference was indeed different and for him, the level depended on the money he had. The money was calculated with the current unit as the base and did not count the private property. The money here was the money in circulation.
So the fact remained that he might never reach level 100 as just the lifespan of 180,000 years would not allow him to become a strong person.
He knew that he would die one day and he also needed to get some slaves. The red whale can live for millions of years without aura, and with aura and intent such beasts would last longer. If he wanted such slaves to be wise and clever,they will be wise and clever. He could even corrupt their bloodline and genes using intent such that each future generation would be his slave. But the only problem remained that each generation would have a drop in level by 1. Intent lords had indeed tried to forge their bloodline but any such intent lord had found that all their descendants were indeed limited as they could not forge their bloodline further and the children also turned out to be slaves. Rather than doing so, they would rather just their body be radiated by aura and intent such that their descendants would have a chance of awakening aura.
Humanity did indeed have a method of forging the bloodline that so that the personal intent and bloodline intent would add up naturally as strength and all the descendants would have their own thoughts and will, unaffected by the bloodline intent allowing them to learn their own personal intent and forge the bloodline further in the manner they wanted. But sadly, humanity in this universe does not have it as all humanity had lost connection with the last abode of humanity where all humans from universes meet.
So the only thing that he could do was to live happily hoping to reach a higher level of strength.
