Qin Xuan, a cultivator who traveled through the world of tennis kings, traveled to many countries to hone his skills in order to return home and reach the ultimate state of tennis. With his unique skill "Dragon Roar", he became the god of American streetball and refused the U-17 training invitation.
In the past, he was misunderstood by the youth coach and was expelled from the team, which left him with a thorn in his heart.
After returning home this time, he returned to Neon with a strong force, crushing the Ato Club, awakening the Hyotei people, taking charge of the Fudomine Tennis Club, polishing the strength of the team members, sweeping all kinds of powerful enemies, breaking and counterattacking all the way, vowing to crush the old regrets, overturn the legend of Echizen Nanjiro, and reach the top of the world's tennis world.
