Soon-shin goes to work as the new commander of the Left Cholla Navy. Won Kyun barges in during an officers' meeting and confronts Soon-shin for stealing his post. Soon-shin's officers follow Won Kyun out completely ignoring Soon-shin. When the envoy returns from Japan, the arguments and confusion about the possibility of Japanese invasion overwhelms the royal court. Sonjo accepts Easterner Kim Sung-il's argument that there will not be a war, and Prince Kwang-hae, who had seen the power of muskets, reproaches Sung-ryong for staying quiet. Song-ryong is proud to see that the young prince has matured, and he tells him that he will avoid a war through diplomacy.
