Twenty-year-old Lin Yi is reborn in a parallel world—a world where tennis is the world's number one sport—with the memories of a fallen professional tennis player from his previous life. He was once an unknown player ranked outside the top 200 in the ATP rankings, never having touched the glory of a Grand Slam; now, he's reduced to the "King of Double Weaknesses," utterly humiliated by Zhang Hao 6-1, 6-0 in the Xinghai University team selection tournament. Before the shame has faded, fate throws a shocking twist: the [Tennis Legend System] is activated! Starting with the legendary [Spin ​​Serve] skill of Echizen Ryoma? But he needs to complete 100 anti-physics serve training sessions?!

When the laws of physics crumble on the court, when "patented aerodynamic technology" becomes a fig leaf for a repressed young man—Lin Yi adjusted his non-existent hat, his racket pointing straight to the sky: "They say this isn't tennis?" "Sorry, this is just my first shot in conquering the world."
