In the year 1462 of the Sea Calendar, 13-year-old Yudian enrolled in the same school as Garp and Sengoku, only to be utterly defeated in the Marine Headquarters training camp. In this world of talent and Devil Fruits, Yudian could only rely on hard work and the system. 'Ding! Host needs to run 100,000 laps around Marine Headquarters to reach the maximum level of Six Styles - Shave!' 'Ding! Host needs to poke stones 1 million times with his fingers to reach the maximum level of Six Styles - Finger Pistol!'... 'Ding! Host needs to smash 10,000 mountains with Armament Haki fists to reach the maximum level of Armament Haki!' 'Ding! Host...'
