Yun Heng is a "wandering student" from the Ninth Magic Academy at the edge of the universe - a lonely trainee wandering among galaxies. His courses are not held in classrooms, but in meteor belts, around black holes, and on abandoned space stations. The "Stardust Exercise" unique to the Galaxy Magic System allowed him to communicate with the debris of hundreds of billions of years of stars and decipher the spells from ancient civilizations, but it also made him regarded as a heretic by the orthodox academy. By an accidental dislocation of time and space, Yun Heng discovered a lost cosmic trajectory in the interstellar fog - it is said that this trajectory can allow magic to reorganize the order of the universe, and can also bring the power of the academy to collapse. Yunheng both longs to belong and is determined to explore the truth. His drift is both self-salvation and a challenge to the galactic order. Every planet and every gravitational wave on the journey is a trial. Magic is not omnipotent, and wandering is the truth of destiny. In the depths of the star sea, he will use his identity as a drifter to shake the foundation of the academy and ignite a magical revolution belonging to the galaxy.
