The Dunhuang Hotel's real purpose was to serve as the main agency in Southern China for the world's foremost intelligence agency, "The Dark Division."
As for who founded The Dark Division, even Song Yun did not know, only that the agency had existed for over a hundred years, apparently since World War I.
As a neutral intelligence agency, The Dark Division focused solely on economic interests. As long as the price was right, they would provide any information, regardless of whether you were a government official or a terrorist—it wasn't their concern—and The Dark Division never betrayed their clients' information. That's why Song Yun had always acquired intelligence from The Dark Division in the past.
Such agencies were abundant in the dark world and were known as information providers. With enough money, they could even find out the color of Queen Elizabeth's underwear.
"Song Yun, do you know who did it?" Black Flood Dragon hastily asked as he saw Song Yun running over.
