Zhu da ge the great master will most likely build super navy force while shifting the main arsenal, troop , resources out, and set trap with dummy troop dummy city, once 300k or huge number troop declare victory march into city first wave artillery group counter attack . next let them march much more far from their main supply line and troop spread out into smaller group , than start first wave of counter attack, land bombing and cut off sea road supply with fully ready navy force. the main objective is to create a huge distance for their supply line and isolate huge troop into smaller group , cut off main sea supply line if possible . its more easy to defend smaller size troop and create confusion.
