My Simulated Path to Immortality

How difficult is the path of immortality! Especially in this world of cultivation that has been utterly transformed by a plague! Ordinary people carry the disease, and once a cultivator comes into contact with it, their cultivation will decline at best, and at worst, they will return to the heavens, thus forever separating the mortal and immortal realms; Cultivation techniques cannot be practiced simultaneously, turning the entire cultivation world into a vast dark forest; ... Li Fan, having traveled from another world, harbors great ambitions but can only roll in the dust of the mortal world, wasting his life. Fortunately, at the moment of his death, he finally awakens to a mystical treasure, capable of turning reality into illusion, transforming his real life into a dream, and returning him to the moment he first crossed over! Thus, Li Fan begins his long journey to immortality! In his second life, Li Fan spends fifty years rising to the pinnacle of power, but he cannot find any trace of immortals in the world. Only at the end of his life does he catch a glimpse of an immortal's presence. In his third life, Li Fan exhausts his mind and devises countless plans, but ultimately cannot withstand a single sword strike from an immortal! In his fourth life... ... I, Li Fan, an ordinary mortal, will never regret a hundred lifetimes, all for the sake of immortality!
