Luffy, a son of a wealthy family, witnessed the arrogant attitude of foreigners towards plundering and smuggling Chinese cultural relics when he was studying abroad. After returning to China, he ostensibly became a noble son of Shanghai, and privately formed a team dedicated to blocking the smuggling of cultural relics. During one operation, the team intercepted a gold and jade plate from the Japanese, but they did not know that it contained a map of the Ming Dynasty treasures. Forces from all sides appeared one after another, and the Japanese were in hot pursuit. Luffy, Fang Qiu, and Cannon took the lead and headed to the desert to find out. The three of them followed the clues from the horse bandits and found the entrance to the underground palace. They saved the day and found the treasure. Unexpectedly, the already rebellious Uncle Hong appeared with the Japanese, hoping to rob the treasure and study its poison. Luffy and others resisted tenaciously, and with the help of the Ming Gang, they knocked down the opponent. Uncle Hong fled in a plane with poison samples, but Luffy caught up in time, subdued him in the air, and landed in an emergency before the plane crashed. The poison was destroyed and the treasure was put to reasonable use. Fang Qiu joined the team and everyone began to prepare for the next action.
