The starry heavens stretched boundlessly, with the Myriad Worlds scattered across them like pieces on a chessboard.
Above a colossal sun, amid its countless flames, strange islands of black rock floated in the air.
The temperatures humans could endure were not high. Boiling water would inevitably scald them; they could not remain immersed in it.
Tin was a relatively easy metal to melt, requiring only twice the temperature of boiling water. Lead needed only three times that temperature, while copper required ten times the temperature of boiling water to melt.
Iron, however, required harsher conditions to melt: fifteen times the temperature of boiling water.
Thus, the Human Race had mastered bronze smelting first, and iron smelting afterward.
But compared with tungsten, which only melted at thirty-four times the temperature of boiling water, the other metals amounted to little.
Even tungsten, the hardest metal to melt, would turn to liquid on the surface of the sun, let alone in its even hotter depths.
The temperature on the surface of the sun was at least fifty times that of boiling water.
Even among the Demon Barbarians, the Lords of the Myriad Worlds, none below the rank of Half-Sage could dwell on the surface of the sun.
Yet every member of the Fire Race could survive on the black-rock islands on the sun's surface, where the heat could melt tungsten.
The stronger a member of the Fire Race was, the stronger the flames they could endure.
Beneath a black-rock island three hundred li across, countless flames surged, deftly supporting the island. Whenever the flames grew too fierce, a powerful force diverted them elsewhere.
On this black-rock island stood a full one hundred and thirty-two Fire Race Great Demon Kings, along with three Fire Race Emperor Realm beings.
These members of the Fire Race
