Shao Nian, a former top special forces ace, was recruited into the mysterious "Blackstone Defense" company with his extraordinary talent after retirement. He is lazy by nature, always drowsy even in the most intense tactical simulations, but this appearance hides extreme acumen. His boss, the mean and cold-blooded Lin Mo, regards Shaonian's laxity as a thorn in his side and constantly pushes him to the edge of the most dangerous tasks.
At this time, the company's internally developed immersive battlefield simulation system, codenamed "Cangqiong", developed a strange vulnerability: the tester died during virtual training, but the real body suffered real gunshot wounds due to unknown reasons. As the only tester who can freely enter and leave the "sky", Shaonian is forced to carry a black technology terminal "Ghost Sequence" that can parse virtual codes to intervene in the investigation.
As the investigation deepened, Shaonian discovered that the boundary between reality and virtuality was being forcibly erased by some kind of military force. The enemy troops who fell in the simulator are penetrating the dimension and trying to descend into the real world. A deadly hunt spanning carbon-based and silicon-based devices begins with the intertwining of gunfire and code.
