Main plot: Retired fitness coach Lin Shen accidentally activates the "God of Sports Prompt System" and is involved in unlimited copies across 36 sports fields such as basketball, fighting, and track and field. In each copy, the system will flash "gold tips" at key nodes to accurately identify the opponent's weaknesses or tactical loopholes. Lin Shen relied on his wit and system assistance to fight back from the campus field to the professional league, from the street boxing gym to the Olympic stadium, and finally revealed the truth behind the "infinite arena", which was a virtual training ground created by sports pioneers a hundred years ago to inherit the sports spirit, and became the "champion guide" connecting reality and the training ground.
