The birth of Black Gold Technology has a history of a thousand years in the Xifan World.
In the new era, despite Holy Body Evolution still holding a place in several major Empires, with the strongest being revered as the National Holy Bird by each Empire, rumors of secret weapons developed within each Empire's secret bases now possess higher-strength capable of altering the continental landscape.
Thus, each Empire, living with thoughts of science, civilization, and Cold War tension, is putting forth all its efforts to research larger scale, higher strength secret weapons.
And to accomplish all this, the fundamental resource is Black Gold!
Black Gold is a unique material under the rules of the Xifan World, often spewing from the depths of the earth as black toxic smoke. This requires a filtration reception device to convert it into Black Gold, to realize the new-era Hundred Spirits' Black Gold Technology combat style, materializing into various battle weapons.
