"Retreating enemy is more intimidating than the approaching enemy. By retreating, the enemy seemed to be trying to demonstrate the futility of life." The Royal emissary removes Yi Soon-shin of his authority holding him accountable for the defeat in Wekyo and puts Yu Jung in charge of the alliance navy. Yi's men are furious and distraught, and order begins to fall apart in the camp. The emissary continues to put pressure on Yi Soon-shin threatening to charge him for impiety against the King, but Yi Soon-shin's will to go after the retreating enemy is unshaken. The confusion in Chosunese camp provides an opening for Konishi Yukinaga to launch a messenger ship requesting reinforcements from his allies nearby. Yi Soon-shin is forced to respond by taking military action against the order of the emissary, and the emissary recommends charges of treason against Yi Soon-shin.
