In the Essos continent separated by the "Sea of Mist", young Lin Mo inherited a dilapidated fishing port on the coastal ruins. When the sails of the other world were raised, spices, magic crystals and forbidden technologies flowed along the route. He used a rusty anchor as a starting point, used merchant ships to measure the seven seas, and used ports as chessboard moves. From repairing the rubble of the docks to monopolizing transoceanic trade routes, from resisting pirate bonfires to commanding fleets to break down city-state barriers, his port rose into a giant steel city in the smoke of commercial wars. When the gold coins of the old kingdom collide with the muskets of the new forces, this journey that begins at the fishing port will eventually rewrite the maritime era of the entire continent.
