My Mission Is to Save

He Nantian is chosen by a robot from Blue Star to become a savior of parallel timelines. His mission is to save parallel timelines that have been altered by time travelers and prevent higher-dimensional space from collapsing. But before he can become a qualified savior, he must pass round after round of selection and trials, endure all kinds of emotional torment and the erosion of desire, seek the meaning of life, and find his way home.
