The Strongest Grade-Schooler: From Class Bottom to All-Round Ace

Transmigration? Memories from a past life? Jiang Cheng has no idea. All he knows is that he suddenly became an elementary school student, and a perennial dead last at that! What? Aomine Daiki? I've only heard of Hanamichi Sakuragi. No idea who's better. From then on, Jiang Cheng merged with one character template after another and gained a string of max-level skills. He went from perennial dead last to an all-around prodigy. What's it like when an elementary schooler is explaining calculus, linear sequences, and probability to the teacher one second, then dominating the basketball court with Zone the next? What does it look like when an elementary schooler wins a major literary award, then turns around and shows up at a gathering of business magnates? The god of extreme sports, a rising star in physics, the entertainment industry's kingmaker, the hacker who ends all hackers... When all these labels belong to one person, everyone thinks the world has gone insane. From then on, a new king rises in every field on Blue Star. Except... why is this king still an elementary schooler?
