The entire human race on earth are currently of a single continent now, called the 'The People Republic', with a land mass of over ten million kilometer that are habitable and safe enough, and if a person were to view this continent from a bird eye view, they will see the entire continent is in form of a giant circle with two inner circles.
The inner most circle or the royal city as the people call it, it span over two million kilometer hectare of land in a circle, and it only those families that are still powerful and influential enough to be called royals, presidents, ministers, extremely powerful politicians and top generals in the army from the old earth has a piece of land here to themselves in this city.
The entire inner most circle is surround by technological constructed wall, made to bar anyone who is not authorize from entries, this wall is over fifteen feet in height and twenty five inches in density thickness, made with the best metal found on Mars called Lihet metal, the metal are mined in liquid form and can be bent however you want it but when it finally solidify, its twice as hard as adamantine, it a metal that has the standard condition of Lithium in it liquid form and it has twice more density than chromium in it solid form.
The wall is also equipped with enough laser guns to stop aerial intrusion and also to separate the royal's city from the rest of the world.
The middle circle or the upper city as the people call it, it span for over four million kilometer in circumference of the circle that is the royal city, it only the nobles and wealthy enough people with specific occupation that truly helps the human race in this trying times are allowed to live in and built their workspace here in this section of the continent.
The upper city is also guarded with Lihet metal but instead of a wall, the Lihet metal is made into a highly electricity conductive net with fourteen inches in density, the net circle round the four million kilometer hectares of land that made up of the upper city.
Am sure you my beloved readers can already guess the kind of people who lives in what they called the third circle or the outer city, is meant for the low income people and factories workers, basically it for the poor people and those who were consider middle class people in the old earth, the outer city is also divided into three section.
The first section, which compose of higher class people with substantial income, they are the people closest to the net that divide the upper city from the outer city, and they have the highest chance to go in and out of the upper city whenever they want.
The second section, compose of middle class people with enough income to feed their families and a few servant too, they are further out from the net, and they are majorly managers and team leaders of the company of the higher class people, and they also have a slim chance to be called into the upper city.
The third section of the outer city of the people republic city, is also 'unwritten' divided into two sections too, a section for the few that have gain foot hold in any major companies and people who are servant to extremely powerful and rich higher class people, the second section compose of the slum, people who are factory workers lives here, the sex house and various gang headquarters, and this section is the one closest to the ten million habitable land mark of the human.
Both the royal city and the upper city has four gate each that helps divide the giant circle into four equal part but the outer city doesn't really have a wall or net to protect it like the upper city and the royal city those, but the forest that surround the giant circle has been cut down enough to serve as the indicator of where the land habitable ends, anyone who step out of that indicator are all on their own.
But the truth is that, the most dangerous and mysterious rebel faction has their base out of the land area the so call army claims to be habitable and save, and base on the current situation of the humans right now, three rebel factions has risen up so far since the humans came back to earth against the people who call themselves the 'army' and 'government' that rule and make the law for the betterment of the human race.
