During this tumultuous period, Goryeo momentarily conquered Liaoyang in 1356, repulsed two large invasions by the Red Turbans in 1359 and 1360, and defeated the final attempt by the Yuan to dominate Goryeo when General Choe Yeong defeated an invading Mongol tumen in 1364. During the 1380s, Goryeo turned its attention to the Wokou menace and used naval artillery created by Choe Museon to annihilate hundreds of pirate ships.
