In 330 AD, the Heaven and Earth Sect arose within the Eastern Jin. Its leader, the Purple Aura Star Lord Dong Wanlai, saw the constant strife among the martial arts factions and the countless deaths and injuries it caused. He decided to unite the martial world and put an end to its feuds and grievances.
Years later, Dong Wanlai disappeared, and Qi Jinyuan, the Supreme Sect Leader known as the Chivalrous One Blessed by Fortune, took charge of the Heaven and Earth Sect. In his quest to unite the martial world, he cultivated himself into madness. The Heaven and Earth Sect soon unleashed a reign of bloodshed across the martial world. Within just a few years, it destroyed dozens of sects. Wherever the Four Great Demon Lords went, neither people nor beasts survived, and not a blade of grass remained. At the mention of demons, the martial world trembled, and everyone lived in fear.
After two hundred years of darkness, although the Central Plains martial world remained under the shadow of the Heaven and Earth Demon Sect, the major sects never stopped resisting. The martial world seemed peaceful on the surface, but undercurrents were surging. Calls to destroy the Heaven and Earth Sect continued to spread. As the old generation of demonic leaders died one after another, in 551 AD the major sects of the Central Plains joined forces to attack the Heaven and Earth Sect. Its leader, the World-Dominating Demon Lord Long Ao, was defeated by Ciyi, the Lord of the Ninth Heaven, and plunged from a towering cliff. From then on, the sect's main headquarters was destroyed. Its followers were either killed by the orthodox factions or fled to the borderlands beyond the frontier, where they changed their names and withdrew from the affairs of the martial world.
A hundred years after the Heaven and Earth Sect was eradicated, the major sects of the Central Plains flourished, producing one hero after another. The Ten Thousand Gods Palace in the east, the Spirit Gloom Valley in the south, the Famous Sword Manor in the west, the Northern Darkness Palace in the north, and the Heaven's Listening Pavilion at the center formed a new balance of power among five great factions. A new storm sweeping across the martial world was about to begin.
