Immortality Simulator

When Li Fan transmigrated into a new world, his life seemed unremarkable. He was moderately well-off, with a wife and children, but nothing extraordinary. Everything changed upon his death, when he awakened the ability Return to Truth: the power to virtualize an entire lifetime's worth of experiences, run it as a simulation, and return to the age of twenty armed with that knowledge.With this ability in hand, Li Fan finally saw a chance to pursue the dream he had always harbored: eternal life. In other words, the path of immortal cultivation.But the world of cultivation was nothing like the paradise he imagined. After countless generations of cultivators plundering heaven and earth, the heavens had struck back. Mortals now carried the Immortal-Mortal Miasma within their blood, a disease that, when encountered by cultivators, led to cultivation decline and death. No technique could be practiced by more than a single person. Calamities descended from the Heavenly Dao without warning.In such a hostile world, where even the heavens themselves resist immortal cultivation, can Li Fan truly seize eternal life? Or will he meet his final end, his Dao dispersing back to heaven?
