Pokémon: Teacher, I Want to Take a Day Off.

[Pokémon + time travel + starting from a young age + hidden boss + easy daily life + single female protagonist] When he was one year old, Lin Su traveled through time to the Pokémon world. At the age of three, he awakened the [Legendary Trainer System] and began to grow stronger silently. At six years old, his Pikachu learned moves that only champions could do. At the age of ten, he defeated the first Four Heavenly Kings in a simulated battle. At the age of twelve, he already had six quasi-gods in his team, but he chose to continue attending junior high school. Trainer competition? No, I have to do my homework. Gym challenge? No time, I have to take the final exam. Legendary Pokémon goes berserk? Wait, let me send a message to the class teacher first—— When he was eighteen years old, Lin Su was admitted to the Pokémon Research Department of Magic City University as an ordinary candidate. He thought he could finally live the peaceful college life he had dreamed of. Until one day, Daigo was chased by the original Groudon, Sirona was pressed to the ground and rubbed by the two dragons of time and space, and Xiaozhi was surrounded by an army of mythical beasts. The whole world is looking for the legendary boy. At this time, Lin Su was dozing off in the back row of the classroom. The phone vibrated: [Classmate Lin Su, your application for leave has been rejected. Counselor: What's the reason this time? The end of the world? Lin Su raised his head, looked at Groudon who was breathing fire outside the window, and fell into deep thought.
