Lin Xiaoxing, a sophomore at the police academy, is a hot-blooded and impulsive "waste in life" - full of road-crazy attributes, his cooking skills are a disaster, but he has a "detail radar" that is incredible, and his observation is so sharp that he can pick up the clues missed by others. He has a soft-spoken personality and is easily shy, but he always shows up with amazing courage when encountering difficulties, showing his prowess in the professional field. Lu Chen, the 24-year-old squad leader of the special forces, is a "straight man" with the highest level of force. He is very principled and not good at words, but his ears will turn red when Xiaoxing comes near. He is particularly indulgent towards his confusion and has his own exclusive short-term protection buff. During an accident at the police academy, the road-crazy Xiaoxing accidentally broke into the training site and was subdued by Lu Chen on the spot. The bond between the two began. From thefts around campus, to inter-provincial smuggling cases, to special transnational crime operations, Xiaoxing's talent for details and Lu Chen's iron-blooded strength perfectly complemented each other, becoming a tacit partner in military-police cooperation. They experienced the dangers of flash floods in field training together, worked together to break the investigative deadlock, and protected each other at the critical moment of life and death. They also faced difficulties in the workplace and external resistance together, and grew rapidly in their respective fields. From the restraint of exchanging contact information, to the tacit understanding of fighting side by side, from the care and concern of encouraging each other, to the determination of walking hand in hand, the two used their responsibility and perseverance to write a story about growth, trust and protection. The thrill of counterattack in the workplace, the warmth of two-way running, and the tacit understanding of the military and police cooperation are intertwined in each case and test, and finally usher in a happy ending with the peak of the career and the quiet years.
