A sharp phone ring jolted Lin Yunfei awake from his dream. The voice of Deputy Section Chief Dong Zhichao came through, urgent: “Engineer Qin from the Eighth Institute lost a bag of confidential documents containing important research projects at the train station. This has drawn significant attention from higher authorities; you need to rush to the Railway Public Security Bureau.” When Lin Yunfei and investigator Cao Yang arrived at the bureau, Dong Zhichao informed them that the police had solved the case; it was an ordinary theft, and he needed Lin Yunfei to assist in wrapping things up. While watching the interrogation video of the thief, Lin Yunfei noticed inconsistencies and quickly reported to Director Hong Zicheng. Experienced in investigations, Director Hong sharply realized this could likely be a spy case, decided to take over, and quickly implemented measures. During the identification and screening of relevant personnel from the Eighth Institute, Zhang Quan emerged as a major suspect, but just as they were about to question him, Zhang Quan was suddenly killed. After investigating the scene and questioning witnesses, three potential suspects who might have killed Zhang Quan were detained and interrogated, but their behaviors all seemed logical, and they lacked motives. At this moment, upper management reported that the stolen intelligence might be automatically launched via satellite within 48 hours. Time passed, and the case showed no progress. Lin Yunfei proposed a bold idea... At the critical moment when the stolen intelligence was about to be automatically launched, Lin Yunfei employed special investigative methods to force the overseas spy codenamed "Faceless" to confess, while agents in the field successfully intercepted the stolen intelligence. Just as everyone was celebrating the victory, unexpected news came: another key national aerospace research institution in the city, the Power Institute, had its important research plans leaked overseas... During a case analysis meeting, Director Guan introduced the young female investigator Shi Hui and announced her as the new head of the investigative department, specifically responsible for the special task force's investigations. This puzzled the two ambitious deputy section chiefs, Lin Yunfei and Dong Zhichao. To facilitate the investigation, the department decided to send Lin Yunfei into the Power Institute as the deputy director of the office for follow-up surveillance. Using his position, Lin Yunfei meticulously checked all crucial departments, key areas, and important personnel within the institute but found no suspicious activity. At this point, Shi Hui suggested a comprehensive security check across the institute, during which they discovered that K1 samples of rocket fuel were missing, and there were no clues. Lin Yunfei felt guilty for the loss occurring right under his watch. Recalling every detail from the Power Institute, an important figure surfaced in his mind. Lin Yunfei proposed a shocking theory—that Engineer Yuan Zhifang from the Power Institute might be stealing the samples. After thorough investigations and analysis, Lin Yunfei's theory was confirmed: Yuan Zhifang, for the sake of his son, had reluctantly engaged in actions harmful to the country, revealing an overseas spy group codenamed "Diana." The special task force promptly took action, capturing the suspected spies and intercepting K1 samples at the airport. Upon testing the samples, it was found that half of the K1 samples were missing... There must be more dangerous individuals behind "Diana," and identifying who they were became key to solving the case. As the investigation deepened, a mysterious woman came into the investigators' sight—this person was Jin Meng, the chairman of TTC Company, who had interacted with Lin Yunfei before. Investigations revealed that Jin Meng had joined a foreign spy organization abroad and established TTC Company in the city, aiming to steal China's high-tech intelligence in light of the country's reform and opening up. It was suspected that this TTC Company might be an important location set up by the overseas spy organization. Furthermore, Jin Meng was intrigued by Lin Yunfei’s special background as a “Vice Governor’s” relative and was trying to recruit him to work for TTC Company. In light of this, Shi Hui suggested sending Lin Yunfei undercover into TTC Company for close reconnaissance. The foreign spy organization instructed Jin Meng to conduct a thorough investigation of Lin Yunfei, even going so far as to test him by attempting to assassinate Shi Hui. With the close cooperation of Shi Hui and other investigators, Lin Yunfei managed to resolve crisis after crisis, gradually gaining Jin Meng's trust, though Wang Yuelong, in charge of organizational security, remained wary of him. Just when Lin Yunfei was smoothly settling into his work at TTC Company, the formula for the K2 rocket fuel samples from the Power Institute was stolen again...
