In 1995, in the southwest border of China, Lin Yuan, who was only eight years old, witnessed his parents die at the hands of transnational drug traffickers. When he was on the verge of death, he was selected by a mysterious dragon mark and received the ancient inheritance "Nine Turns of Dragon Hidden Technique". From then on, a child embarked on an unusual growth path.
From establishing the "Hidden Dragon Group" to building the global business empire "Long Yuan Group", from the secret training base "Hidden Dragon Villa" to dealing with special agencies of various countries, Lin Yuan weaves an invisible giant network in the dark. He is not only the youngest chief instructor of China's special forces, but also the "hidden dragon" who is known in the international underground world. When a global crisis comes and the most important weapon of the country needs to emerge, the hidden dragon emerges from the abyss and shakes the world.
