After all, killing was killing, and Zhou Tian found this task far too simple. Thus, having understood this world and with absolute confidence in his strength, believing that he could use the rules of this world to enhance his power, Zhou Tian once again began seeking suitable prey.
At that moment, Zhou Tian realized why there were so few living beings in this world, despite it being a vast territory in the Otherworld; the population was even smaller than a lower Monster group. This situation arose entirely because of the rules of this world; consuming other living beings could enhance one's strength, which meant the living beings of this world had to consume others daily to survive or even to gain power. If they couldn't find food, they might not end up as another creature's food, but they would likely starve to death ultimately.
