The System Lures Me into Demonic Cultivation: The Twin Souls' Layered Scheme

One burns with the vow to overturn the hypocritical immortal sects; the other carries the hatred of a slaughtered clan and secretly plots a world-shaking game. Though they seem opposed, through one life-and-death trial after another, they go from mistrusting each other to working in perfect harmony, from sharing spiritual power to joining their souls. As they explore secret realms, face off against sects, and venture onto ancient battlefields, they join forces to overcome one obstacle after another, only to discover that the so-called System is a scheme laid by the Heavenly Dao to prevent the collapse of heaven and earth. Their entangled fates were written long ago into the final chapter of the ancient war between gods and demons... Will they defy the heavens and change their fate, or follow the Heavenly Dao? This bond, spanning the divide between immortals and demons and overcoming life and death, will ultimately become their legend beyond the Ninth Heaven.
