Yi Chao was once the top information broker of the dark web "Scavenger" organization. Because he refused to steal the country's core data for the evil forces, he was hunted by the organization and hid in hiding for three years incognito. He believes that "there is a right way to steal" - do not steal from the poor, do not harm innocent people, and only "repay" the greedy and evildoers. When the city fell into the shady world of capital and power, innocent people were swallowed up, and Yi Chao was forced to return to the world. He uses hacking technology as his blade, information as his chess, and walks between the law and darkness. While fighting against the pursuit of former organizations, he exposes the conspiracy of the powerful and protects the bottom line of justice in his heart in his own way.
