Bai Yi transmigrates into a Xianxia world and awakens a cultivation simulator. By surviving long enough in the simulation, he gains rewards. Numerous attempts at simulating his own cultivation end in failure, leading him to believe he's unsuitable for the path. He then invites the Spirit Sword Sect Saintess, Chen Qianxue, to try the simulator. Following her simulated life, from birth to death, Bai Yi observes her progress and gains insights. The story follows their journey, with Bai Yi learning from the Saintess's simulated experiences.
