There were two locations for the Rainbow Diamond.
One was inside a bank in A City, and the other was deep in the Pacific Ocean.
Inside the bank were six colored diamonds that Mai Xiaomai had stored in a safe deposit box, along with a sapphire, which she probably carried with her.
Based on the coordinates, Chinese, American, and French official organizations, as well as the Black Organization, had gathered their cutting-edge technical staff and equipment and ultimately detected an airplane that had fallen 8,000 meters deep in the sea.
The French used one of the most advanced submarines in the world—the Nautilus.
The Nautilus could reach 97% of the ocean floor and had several successful experiences in deep-sea salvage, including the famous wreckage of the Titanic.
