Black Rock City, a steel jungle where evil breeds in the shadow of skyscrapers. Here, conglomerates monopolize the economic lifeline, politicians collude with gangs, police badges are reduced to decorations, and the night is a hotbed of crime.
Twenty years ago, the young Lin Mo witnessed his parents tragically died at the gunpoint of a power struggle to prevent a conspiracy, but the official closed the case hastily as an "accident." Overnight, the favored man of heaven became a lonely soul bearing a blood feud and was sent overseas.
Twenty years later, Lin Mo returned as the "sole heir to the Blackstone Group." During the day, he was a playboy among celebrities and powerful people, covering up the coldness in his eyes with indulgence; at night, he transformed into a "night watchman" wearing high-tech uniforms, wandering in the dark corners of the city. Without superpowers, he used his billions of wealth to build cutting-edge equipment, spent ten years of hard work to develop peak fighting skills and investigative abilities, and declared war on the entire corrupt power network as a mortal.
His appearance was like a sharp blade piercing the darkness, shocking the street thugs and shaking the oligarchs behind the scenes. But as the investigation deepens, he discovers that the death of his parents is just the tip of the iceberg, and an ancient conspiracy that can subvert the entire city is quietly resurrecting. Gang godfathers, mad scientists, mutants, and even "ghosts" hidden within the police force have all become his mortal enemies along the way.
On this lonely road of revenge and protection, he is not completely alone - his loyal butler is his backing, the righteous policewoman is his hidden line, and the mysterious technical genius upgrades his equipment. But trust and betrayal are intertwined, truth and lies are entangled, Lin Mo must find a balance!
