New Hangzhou, a city that stood out in Thainan's history, sunk when destruction came, but after the cold era passed, the people in the shelters still resiliently rebuilt civilization.
Even in that era, the settlement with a heart for the Earth Union was only left here, but these remnants rebuilt the city, established the Union, and nearby small settlements gradually chose to embrace this city that still had order—in that era, order was a virtue not easily obtained as it required strength and a heart of stone to forge.
As the city expanded, more and more settlements and cities that had forgotten the Union's existence but still wanted to recast civilization joined in, thus the New Hangzhou Union was established.
