The nine kingdoms of Lingzhou have been ruled by the emperor for more than a thousand years. The land of Lingzhou is good at producing mysterious energy, which is regarded as the source of practice by the Taoist priests all over the world, and has derived the mysterious art. The eight princes each led a national scholar to protect the emperor. At this time, Emperor Pei was the eighth generation of the emperor, ruling the nine kingdoms according to the power of heaven, and holding the mysterious scrolls passed down by the ancient gods. In the eleventh year of Shengyuan, the Fusang tree, the ancestral vein of Lingzhou, withered for no reason, and the tyranny of the emperor also made the world turbulent. In the end, the eight princes formed a coalition to set off the "Nine Ying Rebellion", overthrew Emperor Pei, burned Wangdi City, and the nine kingdoms split, each with ambitions, but the princes of all parties checked and balanced, and they did not dare to take the lead without authorization. They had to elect the royal family Emperor Jun to the throne, which was actually a puppet kingship, but because of this, Wangdi City became a free land, and all countries could enter and exit freely. Since then, the world has been in chaos, and the princes have been fighting openly and secretly. The mysterious sect "Tianji Sect" took the opportunity to rise and wanted to do something. However, the world was in turmoil, and the schools of alchemists each established their own faction, relying on the eight princes and the emperor, and the separatist chaos became more and more intense. However, because the nine countries all had the same Xuanbing technique of destroying countries, they were evenly matched, and for a while there was no war to destroy countries, until the awakening of an alchemist disciple actually set off a bigger storm... While investigating a strange case in the martial arts world, the young knight Xuan Qi accidentally met young heroes such as Mu Xuan, Feng Lingyue, and Dan Zhu. The different destinies of several people intertwined, and they accidentally solved the mystery of the ancient civilization left over from the Lingzhou continent, and together they embarked on a journey to find the source of the turmoil in the Lingzhou countries.
