My Simulated Path to Immortality

The path to immortality is fraught with difficulty! Especially in this cultivation world, utterly altered by a plague! Mortals carry the disease; if immortals come into contact with them, their cultivation will at best decline, and at worst, they will be banished from the mortal realm, forever separated from the immortals. I, having transmigrated here with boundless ambition, am destined to toil in the mortal world, wasting my life. Fortunately, at the moment of my death, I awaken a wondrous treasure, capable of transforming reality into illusion, turning my real life into a fleeting dream, returning me to the moment I transmigrated! **Thus, I begin my long and arduous journey of reincarnation!**
