Academic Underdog's Comeback? No, I Hold the Nation's Most Powerful Weapon

[Comeback, growth, science and technology, System, no female lead] In his first year of high school, he was a deadbeat student who slept through class and ranked at the bottom of every exam, the very model of failure whom teachers described as “a hopeless case.” Then one day, the student suddenly died. Lin Ye, a second-year college student from another plane who had died saving someone, possessed his body and unlocked the Super Comeback All-Subjects Top Student System! (The System, for short.) The tasks are too hard? No, they're just routine. Academic Olympiads? He sweeps everything from city-level contests to international ones, collecting gold medals by the handful. Tsinghua and Peking University compete to recruit him? The moment he unlocks blueprints for cutting-edge technology, the whole world finally understands: This isn't just a top student making a comeback. He's a strategic asset to the nation, propelling humanity's most advanced technology into the fast lane!
