Lost Dragon City: I'm Looking for Dragons in Lop Nur

[Tracking espionage | Adventure suspense | Lost civilization | Grammar thriller | Family mission] Legend has it that before Lop Nur became the "Ear of the Earth", there was a highly developed prehistoric civilization. "Shui Jing Zhu" says: "Dragon City, so Jiang Lai is empty, and Hu is a big country. The Puchang Sea overflows and covers his country. The city foundation is still there and it is huge. It starts from the west gate in the morning and reaches the east gate in the evening." This prehistoric civilization was called "Dragon City" because it actually had dragons. No one knows where it came from or why it disappeared. In the thirteenth year of the Republic of China, Jiang Xinbai, a returned intelligence officer, was ordered to track down the remnants of the Russian White Army that had sneaked into Lop Nur, only to discover that deep in the desert lay a prehistoric underwater royal city that surpassed human cognition, and his own bloodline was the only key to unlocking this dragon city.
