How to get the hiding place of Merchant King 1?

Complete more tasks of the president and get promoted. Then one day, the governor will give you a map fragment and go to pubs all over the country. Sometimes people will sell other parts of the map (if not, they will go in several times) and buy them back until a red cross appears on the map, which is the location of the hiding place. When we sail past, there will be a small animation saying that we have found a hiding place.
