Lu Chen was once the ace sniper of the top special forces, but due to a well-planned "accident", he was framed for treason. His comrades died tragically, and he himself fell into the abyss. Three years later, he returned from hibernation as a "black market hacker". On the surface, he was a wanderer hanging around casinos, but in fact he was a hidden agent secretly planted by the National Security Bureau, codenamed "Ghost."
He wears gold-rimmed glasses to pretend to be elegant, can tamper with surveillance data streams by tapping the keyboard with his fingertips, has a miniature explosive device hidden in the pocket of his suit, and can decipher Morse code in the drinking room of a wine shop. From hijacking the encrypted communications of international spies, to setting up a counterattack in a transnational financial scam, to sneaking into a biological laboratory to seize deadly virus samples, Lu Chen's every action is on the edge of life and death.
The former traitor's reputation must be cleared, the blood debt of his comrades must be repaid, and the "shadow organization" hidden in the dark must be uprooted. When hacker technology becomes the sharpest weapon, when the icy edge emerges from the mask of a playboy, Lu Chen tells you with a series of reversals of "defeating the strong with the weak": real agents never use guns to speak, but only use wisdom to kill!
