Ling Yue, the ace of the "Dragon Group" of China's top secret service organization, was betrayed while performing a transnational anti-terrorism mission and lost his memory after falling into the ice. Three years later, he was lurking in Binhai City as an ordinary security guard. However, due to an unexpected kidnapping case, he was forced to display his amazing skills and was targeted by all forces.
The former enemy "Black Scorpion" organization is closing in on him, trying to seize the secrets of the "Stardust Project" that remain in his mind; the mysterious beauty reporter Su Qingyuan has repeatedly tested him, making it difficult to tell whether his identity is true or false; the old members of the Dragon Group suddenly appear, bringing about a more cruel internal screening.
Ling Yue, who lost his memory, relied on his fighting skills and criminal investigation instincts in muscle memory to find the truth in the fog: "Who am I? Where is the betrayer hiding? What kind of shocking conspiracy is hidden behind the Stardust Project?"
From the desperate fight in the underground black boxing ring, to the secret room espionage war on a transnational cruise ship, to the virus crisis in the biological laboratory, Ling Yue holds a cold blade and rebuilds his legend amidst the light and shadow of swords. When the memory fragments were pieced together, he realized that he had been trapped in a huge network spanning the military, government and business - "Anyone who stands in my way will be killed no matter how strong he is!"
