When war becomes a commodity, loyalty is the most expensive currency. Ling Feng, codenamed "Hades", is a former top soldier of the Chinese Army's "Siberian Tiger" special forces. He was forced to retire after disobeying orders to save his comrades, and entered the global mercenary battlefield alone. From the deserts of North Africa to the snowfields of Eastern Europe, from a single-handed lone wolf to a mercenary king commanding three hundred elites, he spent ten years building a private military empire that was feared by the intelligence agencies of various countries. There are no systems here, no golden fingers - just ballistic calculations, tactical deductions and brothers who depend on each other for life and death. When the CIA, FSB, and Mossad jointly launched the "Twilight of the Gods" purge operation, Ling Feng and eleven core members had to answer an ultimate question amidst the hail of bullets: Do mercenaries count as soldiers? And his answer will shake the entire order of modern warfare.
