Naruto Bloodline Theory? It's Just Trash

574. Endless Chakra! 10 Billion Energy Warriors!

In Mingren's previous life, in Earth's human world,

industry had been highly developed.

There was far less natural vegetation.

The human population had also approached the threshold of 7.9 billion.

Yet the world of Naruto Ninja had only 700 million people and possessed an exceptionally flourishing natural ecosystem.

In other words... there would only be more living creatures, never fewer!

Even if one used the population numbers of species on Earth from his previous life, the result would still be an astonishingly massive figure!

For example... there could be as many as "one trillion" mammals!

They included rodents such as rats and beavers, as well as bats and other winged mammals. These animals shared one trait: they fed their young with milk secreted from mammary glands.

Then there were reptiles and amphibians, numbering roughly "one hundred trillion" in total!

Biologists had once discovered that the forests of India contained ten thousand reptiles per square kilometer, while Puerto Rico's Luquillo Experimental Forest astonishingly had as many as 3.5 million reptiles per square kilometer!

Next came fish, whose total population reached 10 to the 15th power!! Ten times that of reptiles!

As for earthworms, at 10 to the 17th power; dust mites, at 10 to the 17th power; and terrestrial arthropods, at 10 to the 19th power—they could simply be ignored.

Just counting mammals, reptiles, amphibians, and marine fish,

the numbers had already reached an utterly terrifying level!

And one had to remember...

the animals in the world of Naruto Ninja could not merely grow to normal sizes.

Six-meter-tall tigers!

Eighteen-meter-tall toads!

Giant snakes dozens of meters long!

Even giant turtles several kilometers long!

Such creatures could be found everywhere!

The amount of Chakra contained within them was comparable to that of who knew how
