Lu Xiu, the top student in high school, seems to only study hard, but in fact he has been dormant for ten years, mastering the King of Tennis system and possessing many top tennis skills.

While competing in the Open to win the championship, he also fought against the enemy's plan, vowing to make a comeback, maintain the school's Class A qualification, and reach the top of tennis.
