Global Class Change: I Ended the Apocalypse Early

After the spiritual qi revival, everyone can change classes. Su Ni, a transmigrated person, awakens the long-lost hidden class of a cultivator, but with no spiritual roots, he is trapped at the first level of Qi Refining for three years and becomes the laughingstock of the whole school. At the end of his rope, he unlocks a life-simulation system for cultivation that lets him forecast his future each week. By reviewing life-and-death simulations, he can obtain top-grade spiritual roots, ancient immortal arts, and endless spirit stones, while avoiding the deaths of friends and family, the dead end at Demon-Suppressing Pass, and the apocalypse in advance. From a good-for-nothing cultivator, he rises to command the path of cultivation and crush every crisis in the world!
