The desert's yellow sands rose into the air.
Two dust dragons streaked rapidly past, cutting their way toward the outskirts of Xuanji City with astonishing momentum.
As the capital of a kingdom, it had sentries stationed a hundred li away. Thus, before Li Tianyu arrived with two Imperial Guard Armies, the entire Xuanji City had already been alerted.
Crimson light rose from within the city, enveloping the entire city in its glow.
Billowing smoke appeared above the city, and a muffled roar came from within—more soul-shaking than rolling thunder!
Within the thick smoke, the vague outline of scales and claws could be seen, as if a gigantic beast were lurking inside.
This was Xuanji City's city-protecting grand array—the Sacred Flame Demon Subduing Array!
It was said that several hundred years ago, a Ninth-Grade Exotic Beast had run rampant across the desert, slaughtering people and throwing the entire desert into a state of panic.
Later, that powerful Ninth-Grade Exotic Beast was slain by a Martial Saint!
That Martial Saint, who had risen from the desert, unified the entire region and established a vast empire.
The capital at that time was Xuanji City. The Ninth-Grade Exotic Beast he had slain was used as the raw material and embedded into the grand array, forming the Sacred Flame Demon Subduing Array that existed today.
More than five hundred years ago, the Grand Ancestor of the Great Blue Dynasty swept across the world. Yet in the end, he had been unable to completely destroy the Grassland Royal Court and the desert empire of that era, incorporating the grasslands and desert into the territory of the Great Blue Dynasty.
The reason was that both the Grassland Royal Court and the desert empire possessed Peak Experts—and not merely ordinary Peak Experts, but the very pinnacle among them!
