Regarding the Western Region's Thirty-Six Kingdoms, Su Xin had also delved into some detailed materials, and his conclusion could only be summarized in two words: peculiarities.
In ancient times, the land of the Western Region was indeed prosperous, and moreover, the Emperor of Mankind had ascended to the heavens without completely annihilating the Western Region; the First Dynasty thereby completely collapsed, thus the Thirty-Six Kingdoms of the Western Region were preserved.
However, had the Thirty-Six Kingdoms of the Western Region developed normally, they could have grown into a major country like the Golden Khanate, based on the resources of the Western Region. Unfortunately, the Western Region itself was not up to par, and their internal strife was excessively severe.
Not only was there fighting between the kingdoms, but sometimes a single kingdom could be split into a host of minor states.
