Late one night in 2019, Binhai City was shrouded in thick darkness, with only sporadic lights twinkling in the night sky, casting a mysterious veil over this sleeping city.At this time, a man wearing glasses quietly sneaked into 901“ of the city center.This seemingly ordinary building actually hides the country's important scientific research data and is the core lifeblood of the country's scientific research field.With superb skills and familiarity with the institute, Gao Xichao skillfully avoided the surveillance cameras and unlocked the security doors one by one.His goal is to obtain China's aerospace minutes and documents.However, he did not know that the national security department had already targeted him.Guo Weijie leads an elite security team and pays close attention to his every move.Just when Gao Xichao successfully copied and copied the documents, a sudden unknown phone call broke the tranquility.The man on the other side anxiously asked him to transmit the compressed package immediately and gave him a tight time limit.Guo Weijie immediately realized that this might be the opponent's trap and quickly instructed Zhou Jia to intercept.

Unfortunately, the compressed package was just a decoy thrown by the enemy, and their actions were exposed.Immediately afterwards, the entire building fell into darkness.Guo Weijie's heart was alarmed, and he immediately led the security personnel to act quickly in an attempt to catch the infiltrator.After Gao Xicao realized that he had been discovered, he tried to escape, but the agile Guo Weijie had been waiting for a long time and pushed him to the ground.Under the dazzling light, Gao Xichao's fearful eyes revealed his true identity and the organization he served.At the same time, the man on the other end of the phone disappeared without a trace like a ghost, leaving only a cigarette butt on the rooftop as the only trace of his existence.He ordered the mysterious person to obtain the minutes and documents, and demanded that except for the calculation process and results, other contents must be destroyed.This series of events has brought unprecedented threats to national security.That night, Guo Weijie returned to the National Security Bureau with the climax of his arrest.He checked Gao Xichao's information and found that he had been quietly dedicated to ”901“ for fifteen years.Gao Xchao is talented and has participated in many major projects such as space city infrastructure, launch tower design, and algorithm research and development.However, such an outstanding scientist embarked on a road of no return due to temporary greed.This made Guo Weijie deeply understand the complexity and fragility of human nature.During the interrogation process, Guo Weijie used dual strategies of rationality and emotion to gradually break down Gao Xichao's psychological defenses.Gao Xichao finally confessed that he met an international foundation supervisor named Robert at an international trade fair.This important clue made Guo Weijie vaguely feel that this case might be just the tip of the iceberg, and there might be a more complex conspiracy hidden behind it.So, he immediately reported the situation to his superior leader Qian Yu.Qian Yu attached great importance to this and authorized Guo Weijie to go to the archives room to investigate relevant clues.He told Guo Weijie to work steadily and not to rush for quick success.In the archives room, Guo Weijie met Wang Beili.When she saw the file number, her expression suddenly changed.Guo Weijie checked the files with doubts and found that the International Space Foundation, an overseas organization, had planned and directed the secret theft operation.Yu Bailang, the person who committed the secret theft, has been arrested, but another suspect Zheng Jin has died.The person handling this matter turned out to be Deputy Director Hu Xiafeng.This astonishing discovery shocked both Guo Weijie and Zhou Jia.They began to suspect that there was a traitor within.So they started analyzing the police signal and found that ”0110“, Wang Beili, Hu Xiafeng and others were from the same group of police officers.In order to find out the truth, Guo Weijie invited Deputy Director Luo Ping on the grounds of surprise inspection.

Luo Ping revealed to them his true identity - Wu Yu.Wu Yu was Luo Ping's talent at Xichuan University of Political Science and Law, and Luo Ping spotted his extraordinary talent at a glance.With Luo Ping's help, Guo Weijie was able to continue his in-depth investigation.He learned that Wang Beili was Wu Yu's girlfriend, so he took the initiative to ask her about Wu Yu's situation.Wang Beili did not hide anything and told Guo Weijie in detail what happened in the millennium.At that time, the predecessor of ”901 was still the 14th Academy.Yu Bailang, an engineer from the 14th Academy, copied the newly developed aerospace material data to a USB flash drive and prepared to meet with Zheng Jin, the supervisor, at the bar.Wu Yu, Hu Xiafeng, Wang Beili, Qian Yu and others set up a dragnet near the bar.Wu Yu stared closely at Yu Bailang in the crowd. When he saw Yu Bailang taking out his bank card and hiding the USB flash drive under the table, they stood still, intending to lure Zheng Jin out.However, when Zheng Jin showed up, Wu Yu acted excessively and kicked Zheng Jin to death. This unexpected incident plunged the entire action plan into chaos and crisis.
