Su Yu, a transmigrator in a world where humans and Pokemon coexist, possesses two powerful cheats: the Eye of Appraisal and Skill Acquisition. Just as he prepares to select his starter Pokemon at the academy, a mysterious letter arrives from his future self. The message contains critical intelligence: a Bagon with perfect stats and Champion-level potential will appear near an abandoned power plant, destined to evolve into the mighty Salamence Su Yu has always dreamed of raising.

Armed with this foreknowledge and his unique abilities, Su Yu navigates the school's selection process. While his childhood friend Yan Ruyue secures a Fennekin, Su Yu bypasses the standard starters to intercept a rare Torchic with the hidden Speed Boost ability. As he sets out to claim his destined partner from the future, Su Yu must balance his secret advantages with the competitive pressures of the academy, aiming to dominate the upcoming proficiency exams and rise as a top trainer.
