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.

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?
