How much energy does a Lowest Level World has? 

It was difficult to answer that question. 

Even the Lowest Level World, not only has to create a Protective barrier that protects itself from even the Supreme Level Worlds, it also has to maintain life and distribute 'potential' amongst the different species residing in it. 

The question changes to how much energy does it take to maintain a ridiculously strong shield for thousands of years and support life of millions, if not billions of beings at the same time. 

Not to mention that a percentage of living beings, though small, but still significant enough, would be using more of the World's energy to get stronger only to later fight amongst themselves or outsiders and perish in the process. 

So how much energy is needed to support hundreds of thousands of cultivators, some of whom are strong enough to get recognized even by the Universe? 

Would there be an answer to quantify that number?
