Now the animated TV version has broadcast 389 episodes, the cartoon has been drawn to the 530-word chronology of events of One Piece, and the sea calendar of 900 years ago /620 years, and the world history has entered a blank century. The blank world history 800 years ago /720 ended and the world government was born. At the same time, the Human Law was promulgated to prohibit the relevant interpretation of the original history. Huang Jincheng in Sandia was destroyed to protect historical texts, and survivors began to be isolated to save their cities and historical texts. 500 years ago/Haiyuan Calendar 1020, there are many legends, for example, the magic man Oz made a scene on earth and established the Kingdom of Ba Li, and there are many related records. 400 years ago/Gregorian calendar 1 120 years ago, Governor Wen Brown rolando, the expedition ship of the kingdom of Lunier, set sail from the North Sea and entered Gran Line. 398 years ago/1122nd, the expedition ship Vinbrown rolando arrived in Kaya Island. After many twists and turns, it saved the Sandia tribe, which was almost destroyed by the tree fever, and became close friends with Calgara. After staying for a month, rolando and Calgara parted with a little regret. In the following years, Sandia's golden bell jar rang the loudest bell for her friends every day. 394 years ago/Haiyuan Calendar 1 126 Half of Kaya Island, including Chandia, Huang Jincheng, was washed up on the empty island Skypia by rising water.

Note: WT's description of these 400 years is not rigorous, because both the voyage of the rolando expedition ship, the beginning of the Sandia struggle, and even the death of rolando are all said to be 400 years ago. As far as the current understanding is concerned, it can only be said that these 400 years are a large-scale estimate. (WT is sloppy, I can't be casual ~ But then again, since WT is so casual, why am I so serious? 208 years ago/13 12, the expedition ship St. bliss in the South China Sea set sail and entered the Grand Lane. A few years later, it was sentenced to "cloud exile" in the empty sea. 200 years ago/1320, the world government announced the formal establishment of diplomatic relations with mermaid island.

Three months later, the Lombard pirates set sail again, leaving their companion whale Bula in his care. Soon after, the captain and a dozen crew members of the Lombard pirate "York Spot" were infected with an incurable disease. With infinite regret, York finally decided to leave Granville on an old ship. The rest of the Lombard pirates put on new ships, and Brooke continued to sail as the new captain. Unfortunately, the group was destroyed by a powerful enemy in the Devil's Triangle. Before his death, the Lombard Pirates performed their last chorus and recorded their voices with a sound clock.
