Immortality Simulator

Li Fan's transmigration to a new world began with an ordinary existence: a comfortable life, a wife, and children. His life's trajectory dramatically shifted after death, however, when he awakened the ability "Return to Truth." This power allows him to simulate an entire lifetime, gaining invaluable knowledge and then returning to his twenty-year-old self, armed with that foresight. This newfound ability presents Li Fan with an opportunity to pursue his lifelong dream of eternal life through immortal cultivation. Yet, the cultivation world is far from the idyllic realm he envisioned. Centuries of exploitation have provoked the heavens, and mortals now carry the Immortal-Mortal Miasma. This disease causes cultivation decline and death upon contact with cultivators. Furthermore, cultivation techniques can only be mastered by one person, and the Heavenly Dao unleashes sudden calamities. In this perilous world, where even the heavens oppose immortal cultivation, can Li Fan achieve eternal life, or will his pursuit lead to his ultimate demise?
