The protagonist Chen Feng, 26 years old, was originally the ace commando of the "Blade" special forces in the Southeast Theater Zone, codenamed "Ghost". He has a calm and decisive personality, and is good at psychological games and close combat. However, he suffered heavy psychological trauma when he witnessed his comrades being betrayed and sacrificed by gang insiders during a cross-border anti-drug operation five years ago. After he retired, he concealed his name and lurked in Linhai City as a courier, secretly tracking down the "Venomous Snake" organization that sold out intelligence back then. In order to get closer to the core target, he took the initiative to infiltrate the "Long Xinghui", an emerging local gang. On the surface, he was a fierce and aggressive Ma Zai, but in fact, he worked step by step and used special operations thinking to disintegrate the gang system. Growth arc: From a lone wolf burdened with hatred, to regaining military faith in the cracks of black and white, and finally using the underworld identity as a cover to complete a fatal blow to a transnational criminal group.
