Chen Fan transmigrates into the Star Cluster Universe and becomes the nominal leader of the United Earth Empire. By this point, the UEE has long been controlled by pro-alien heretics and alien powers. Pureblood humans have been reduced to an oppressed, enslaved underclass, their dignity and bloodline trampled at will. Chen Fan is nothing more than a powerless puppet.
In this desperate situation, the Fourth Calamity Rising System activates, granting him abilities such as Pureblood Will, Rousing Oratory, Spreading Sparks into a Blaze, and Technological Analysis. With the System's support, Chen Fan delivers a stirring speech that ignites the pent-up fury of pureblood humans across the UEE, suppressed for decades.
At the Froststar Council, he seizes power with an iron fist, purging alien lackeys and human traitors. The Red Tide sweeps across the globe as he expels the aliens, abolishes pro-alien policies, and establishes the supremacy of pureblood humans as national policy. From puppet leader to master of humanity, he reorganizes the military and advances technology, forging scattered humanity into an iron-blooded army.
The weak UEE falls, and a newborn Human Federation rises amid the flames of war. Facing alien counterattacks, the might of a fallen empire, and the threat of galactic calamities, Chen Fan leads the Human Federation across the stars, reclaiming lost territory, building colossal machines, and waging war on every front. He vows to plant humanity's flag across the galaxy and make the declaration of human supremacy resound throughout the universe, forging humanity's undying glory among the stars through iron and fire.
