Chen Mo was once an outstanding commander of the "Phantom Forest" special forces, but because he disobeyed an AI command to save his comrades during a mission, he was sentenced to "memory confinement and transformation" by a military court - part of his memory was sealed and stored, his body was bioengineered and implanted as "wetware" into the global Quantum Neural Network Tactical System (Q-NTS). Today, he is no longer a soldier in the traditional sense, but an "Agent" of the Q-NTS system in the real world, code-named 739.
Under the supervision of the "cardinal" at the center of the system, Chen Mo relied on the "optimal solutions" calculated by the system to perform various high-risk tasks. His actions were efficient but often ruthless. He continues to encounter challenges from another product of the human transformation project who calls himself "Shepherd". This person firmly believes that emotions are weaknesses, pursues pure "evolution", and regards Chen Mo as a failure.
When performing tasks, Chen Mo is often troubled by sudden memory fragments and a sense of dissonance. Once, the system ordered him to sacrifice an innocent civilian to ensure the success of the mission. Chen Mo obeyed his inner resistance at the critical moment (seemingly "violating again"). As a result, he accidentally avoided a greater crisis and obtained an encrypted beacon pointing to his past.
Chen Mo began to doubt the ultimate purpose of the system and the truth behind his "conviction". With the covert help of technician "Cardinal" and the external investigation of war correspondent Lin Sha (who was suspicious of the official report on Chen Mo's mission that year), he took advantage of mission breaks and relied on intuition gained from occasionally "cheating" or "shielding" the system to conduct secret investigations. He found
