Ten-year-old Ling Ye, a longtime fan of "Haikyuu!!", accidentally travels to the world of the original series, where he encounters a young boy of the same name, who is caught in a conflict and forced to activate the "Volleyball Extreme System." After using too much force to protect himself, he is forced to take a year off from school. Through the system's closed-door training, he develops core attributes like strength and jumping ability to levels far beyond his peers.

After returning to school, Ling Ye's "violent smash" defied the stereotype of "fighting." In a friendly elementary school match against Tobio Kageyama, his oppressive style left a lasting impression. However, the controversy forced him to move to the United States with his parents for three years. In the American league, his aggressive style adapted to the competitive landscape, setting numerous records and earning him the nickname "The Thunder Slammer of the East." He gradually grasped the art of blending tactics with violence.

After returning to Japan at the age of 15, Lingye enrolled directly at Shiratorizawa High School as a special recruit, partnering with ace player Ushijima Wakari. His playful and playful personality contrasted sharply with Ushijima's aloof and serious nature, yet on the court, the "Lingye containment + Ushijima finishing" combination became a formidable offensive force. From reconciling his past with Kageyama in the prefectural tournament to breaking down Inarizaki's double-setter strategy at the national tournament, he ultimately won the championship alongside Ushijima, redeeming Shiratorizawa's long-standing regret.

The work is assisted by a system, focusing on Ling Ye's growth from "reckless" to "core of the team", showing the contrasting bonds between the two male protagonists and the passion of the volleyball boys fighting for their dreams. It is not only an extension of the feelings of the original work, but also writes a legend unique to "Thunder and Ice Peak".
