Three thousand worlds, the worlds are self-contained. In ancient times, the drama of endless wars and battles for territory has been going on for tens of millions of years. People are tired, demons are tired, immortals are tired, demons are tired, and even ghosts are tired. So several powerful people came together to divide the regional lines from all walks of life, and prepared to peacefully coexist without interacting with each other until death - this is a beautiful idea. The actual situation is that the predators don't like each other. It's considered peaceful to roll up their sleeves and lift the table, let alone those who want to kill each other just by raising a sword after a few words of disagreement. I thought I could demarcate the border in just a few sentences, but in fact it turned out to be a three-hundred-year war of words over three centimeters of land. Therefore, the final result is to withdraw from each other thirty realms and put an end to territorial disputes.
What a coincidence that the Qingqi Realm is exactly one of the thirty realms.
