Jiuxiao Cold Blade Zheng Tianlu

From the end of the Hongmeng Era to the first year of the Taichu New Calendar, the entanglement between immortals and demons spanned three thousand years of time and space; the thirty-third heavenly immortal world with the Nine Heavenly Palace as the core, the Nine Nether Demon Realm with the Dark Abyss Demonic Realm as the center, and the Broken Void Battlefield connecting the two realms; the immortal world adopted the "Tiangang Thirty-six Divisions" militarized management system, and the demon world followed the "Nine Hells Blood Alliance" clan inheritance system. The two worlds maintain a delicate balance through the "Abyss Rift" until the protagonist obtains an ancient artifact to break the pattern.
