My Simulated Path to Immortality

The path of immortality is truly difficult!
All the more so in a cultivation world that has been completely changed by a plague!
Mortals carry the disease, and if an immortal comes into contact with it, at best their cultivation weakens, at worst, they return their Dao to the heavens. Thus, mortals and immortals are forever divided.
I transmigrated here, full of grand ambition, yet could only struggle within the mortal realm, wasting my life away.
Fortunately, at the moment of my death, I awakened a mysterious treasure, one that could turn truth into illusion, transforming my real life into nothing more than a fleeting dream, allowing me to return to the moment I first arrived!
