The so-called "Independent City" was originally supposed to be a country. However, when the district began evolution, this country was destroyed. The remaining people of this nation mostly gathered in this city. The country that replaced the government of the destroyed nation established a district government. To appease the surviving people of the destroyed country, they allocated Mao Tong City to them, allowing them to self-govern and establish their own player law enforcement team, free from oversight by the higher government.
