Treasure Island, a famous novel by Scottish writer Stevenson, tells a well-known adventure story, mainly about the thrilling struggle between pirates and captains for the treasure of a desert island. At the end, the author suggests that there are still a lot of treasures hidden somewhere on the desert island. Treasure Island is written in the background of Cocoa Island in the Pacific Ocean, which is located 480 kilometers off the coast of Costa Rica and was once a rest stop for pirates in the17th century. The pirates loaded and unloaded and buried the looted treasure here, adding mystery to this nameless island. It is said that there are at least six treasures buried on the island, among which the treasure in Lima, Peru is the most striking.

1820, Lima was still a Spanish colony. When the revolutionary army led by the Peruvian national hero Bolí var, known as the "liberator", was about to attack Lima, the Spanish governor of Lima fled in haste. He put the treasures he had been looking for for for many years, including the golden candlestick, the golden plate and the life-size golden statue of the Virgin Mary, on a sailboat named "Dear Maria" and then ran away. Unexpectedly, at sea, the captain made a fortune and killed the Spanish governor. To be on the safe side, the captain put the treasure in a mysterious cave on Cocoa Island. In the later days, he never found a suitable opportunity to go back to Cocoa Island and take the treasure. Until 1844, the captain died, leaving a treasure map that was difficult to distinguish between true and false. This picture was mixed with various treasure maps that were later circulated, which tempted many people to go to Cocoa Island and try to find the captain's treasure. Perhaps too mysterious, too false and too secret, these legendary treasures are still dark and charming. 1978, an unexpected thing stunned all treasure hunters: the Costa Rican government closed Cocoa Island on the grounds of protecting the ecological environment and did not allow anyone to dig it. But what new secrets are hidden in it? Will the treasure of Treasure Island be buried forever?
