Lin Zhengyang, a young police officer in the Municipal Bureau's Criminal Investigation Detachment, was demoted to the archives bench because of his upright personality, which offended his superiors. He thought his criminal investigation career would be bleak, but he was accidentally bound to a "counseling system" with a strange style. The system is timid and fearful, but its skills are hidden. From electric current warning to holographic projection, from memory tracing to form materialization, every upgrade adds a key step to Lin Zhengyang's investigation.
In order to clear the grievances of his master Zhang Tiejun and bring the mastermind behind the scenes to justice, Lin Zhengyang started the road of hard-core criminal investigation with this invisible system that "did not dare to see people". He used "trace reasoning" and "detailed insight" as a cover to cover up the existence of the system. Starting from ordinary cases, he gradually uncovered the corruption cases hidden in the dark. He followed the clues and led to major transnational cultural relic smuggling and money laundering cases, and launched a desperate battle with the evil forces headed by Wang Mingde and the protective umbrella behind them.
In the confrontation at the airport, facing the murderer holding the hostages, the system current shield secretly protects the master, and the range resonance instantly defeats the enemy; in the court, the eye of truth sees through the criminal's luck, the electric mouse integrates the bioelectric memory, and the ironclad evidence shatters all sophistry. Along the way, he had doubts and dangers, but he always adhered to his original intention of criminal investigation. He even met the love of his life, Su Qingyan. The two went from investigating cases side by side to being together in life and death, becoming the golden partner of the criminal investigation detachment.
From the frustrated police officer in the archives, to the key criminal investigator who solved major cases, to the "police legend" who was promoted to the deputy captain of the criminal investigation detachment; from the timid and invisible coward system, to the materialized electric mouse that bites wires and makes mischief, one person unites and achieves each other's achievements.
