Sonjo receives the victory report, but he is not entirely pleased by the fact that Soon-shin did not press on to recapture Pusan Fort. Losing the command of the sea of Kyung-sang Province, the Japanese warriors are beginning to think that the Toyotomi Hideyoshi's ambition to conquer Ming was a pipe dream. Jotai tells Hideyoshi that they still have a chance if they take Jinju Fort and use it as a bridgehead to Cholla. Hideyoshi issues the order and the Japanese forces begin to converge at outside Jinju Fort. Soon-shin, Kwon Yul and Constable of Jinju Kim Shi-min have a secret meeting. Kwon Yul offers to send military aid to Jinju, but Kim Shi-min declines the offer and asks that they stay where they are and stop the Japanese from converging in Jinju.
