The future...
Many viruses have broken out throughout human history. No matter the cost or how many people died, humanity ultimately defeated them. But not this time. The virus kept mutating. Vaccine development caught up with the second mutation and even the third, but failed to keep pace with the fourth. Some nations started wars to distract people, escalating them into wars fought with the most advanced scientific weapons. The entire world was left shattered and on the verge of collapse.
Humanity lost nearly one-third of its population to the virus and another third to war. After the war, the nations were reorganized, and borders between countries disappeared. Humanity united as one to rebuild its home. History would call this the Human Era. Most people believed humanity was gradually entering an era of spiritual civilization. In this period, humanity had no political power or money, and the entire world was one.
Year 37 of the Human Era: the Western Frontier suddenly declared independence.
Year 39 of the Human Era: the Southern Sea City declared independence.
In July of the same year, the Central Region formed a federation and declared independence.
Year 40 of the Human Era: the Arctic Lands declared independence.
Year 41 of the Human Era: the Eastern Continent declared independence and was named the Eastern Capital.
The federations and regions announced that they would encourage cultivation of Qi and spiritual energy, and jointly establish Spirit Battle Squads to govern illegal conduct by humans and Qi practitioners.
The Human Era became history. The calendar was renamed the Spirit Era.
