Lin Kai, a veteran football game player, is transported to 2002 with a modified training system, becoming a Chinese player for Fiorentina in Serie A who is about to be released. With only one month left, he must prove himself in the hellish Serie A. Utilizing a system bug that allows for multiple improvements through training, he employs unorthodox methods like "self-throwing and shooting to practice heading" and "hiring people as practice targets to practice dribbling." He quickly transforms from a defensive blue-collar worker into a prolific all-around midfielder. When everyone thinks he's just a dirty worker, he saves the team with a stunning long-range shot in a crucial match. He will team up with the "God of War" Batistuta to fight against the "Little World Cup" era with Ronaldo, Vieri, and Shevchenko, growing from a relegation-threatened team's core player to a world-renowned Ballon d'Or winner, making up for the regrets of countless fans.
