Heaven and Earth were fair, they gave the ability to cultivate to every living being.
Yet, the world was ruled by humans who monopolized the means to embark on the cultivation journey.
Those that had accumulated more techniques and spells produced stronger cultivators over the years which allowed them to gather even more resources.
Those cultivators were the nobles of the Utra country.
However, for each noble, there would be hundreds of common people.
A few of them would inevitably have wild ambitions and wouldn't be restrained by the rules of the world.
As soon as they had the chance, they would strive for power, uncaring of the danger that they would have to face.
Humans were ambitious and greedy, they couldn't just sit back watching the minority of them strive for power.
If the rules didn't allow the commoners to cultivate, they would just break them.
Nevertheless, only a small part of those that rebelled managed to survive.
