Crown Prince Sado
During the reign of King Yeongjo of Joseon (1694-1776), the "Muyejebo" was revised and supplemented with 12 additional fighting methods by Crown Prince Sado. A modified form of "gwonbeop" reappeared in this work. The revision, the "Muyesinbo (무예신보, 武藝新譜, "New Compendium of Martial Arts)", was published in 1759.
