Immediately after returning from Belakasser, Weiss activated the established "operational" plan. With the cooperation of the military and the police of the federal security service, the main telegraph lines of Lorraine were monitored, especially the communication with the airport of Belakase, which was recorded and analyzed by special personnel - the reason is simple, the Normans lurking in Lorraine or the traitors who worked for the Normans carried out any operations must be dispatched by the rear, and the information obtained also needs to be transmitted in time. They can set up their own radio stations to transmit via high-frequency radios, but this way requires equipment, training their own radio operators, and being careful to watch out for federal radio detection services. During Brooks' time in Lorraine, the Federal Department of Security Inspectorate identified and raided a total of 10 suspicious targets, only two of which were equipped with radio equipment, and the other eight were none, and it is reasonable to believe that they were secretly transmitting information through public communication lines.

Of the two targets equipped with radio stations, one was completely destroyed by the lurkers, and the other was left with a lot of components and information due to the rush of time, so that the Federal Security Inspectorate used the existing radio technology to master the frequency bands used by the enemy and the method of compiling the code, although it could not decipher the code in time, but it was able to lock the communication frequency through the code rules, and then use radio direction finding technology to search for the source of the telegram. As a result of this struggle, foreign intelligence agents in Lorraine almost stopped using their own radio stations for a long time thereafter – and they no longer used point-to-point direct contact unless absolutely necessary.

About three days later, the joint operation team finally screened out a few suspicious telegrams among tens of thousands of messages, and locked up a few suspicious elements through reverse tracking, but they did not rush to arrest them, but adopted a remote tracking method to monitor their whereabouts. Weiss and Nikolai were not surprised by this, they continued to observe in the shadows, and through the guidance of clues, they roughly determined the department where the enemy intelligence officer was located, fortunately not in the security department, but among the first personnel who entered the factory in advance. It seems that the Normans have long been aware of the existence of this cooperative factory, and have been ready to detect intelligence from the beginning.

In order to find out the information, Weiss and the police used the forces of the military and police departments. At the same time, in order to mislead the enemy's line of sight, they launched an operation against another clue, raiding a target point in the university town of Mason. There are two suspicious elements here, who are very vigilant, and when they find that the situation is not right, they actually take a female student hostage and demand that the police release them. During the confrontation, the Lorraine emergency team arrived at the scene, and professional snipers wounded two thugs, and then the police and emergency response team burst into the scene, and the two fanatics committed suicide by drinking bullets as before.

The clues did not stop there, judging from the information found at the scene, the target of their search for intelligence was the high-end mechanical technology of the Lorraine people, and most of the enterprises of the Industrialists Alliance and the Grumman Group in Lorraine had a cooperative relationship with the Mechanical Institute of the Free University of Lorraine, and they tried to get access to the information of those mechanical technologies through this line, including the latest high-power piston engine design. Although it is far away from the cooperative factory, through these technical materials, an invisible black hand can still penetrate into the technical field, to understand the degree of development of the cooperative factory in terms of technology, and even to explore their specific technical solutions.

Next, the Federal Inspectorate of Security and the local police in Lorraine naturally screened and screened the faculty, staff, students, and even vendors in the university town, leading opponents to believe that the Lorrainians had focused their attention on teaching institutions south of Mason. In fact, they still keep a covert track in other ways. After more than a week like this, the inner ghost lurking in the cooperative factory finally passed the message outside. The vigilant security department discovered hidden confidential information in a nominally sent letter to the newspaper, and based on this discovery, the contact between the inner ghost and the upstream was locked.

Soon, the letter was delivered to Weiss. The content of the letter seems to be just ordinary poetry, and the writer has submitted articles to the newspaper from time to time, and has been published several times, and has received a reasonable remuneration accordingly, so it seems that there is nothing wrong with it, but if you look closely, you will find that some of the hidden hints point to some new technology.

The person who noticed something unusual about this letter was a young man who had just joined the security team. He served in the military, and further back was a liberal arts student at a federal high school. Out of a hobby and study of literature, he was keenly aware that some of the words and phrases in the letter were repeatedly emphasized, which seemed to be reinforcing rhetoric, but these things were highly related to flight, and some technical indicators could be guessed through the meaning behind them. For example, "Soar like a thunderbird above the 33,000-foot clouds, chasing lightning, ignoring the resistance of the wind." This sentence is emphasized twice, and the wording used in each time is slightly changed, which can be understood as a kind of aircraft with high flight altitude and speed, and from the subsequent emphasis in the article, you can spell out specific numbers, and then verify with the cooperative factory, and sure enough, it is consistent with the calculation data of the heavy aircraft.

After consulting with Nikolai, Weiss decided to launch the first phase of the "fishing operation". In order to ensure that the news was not leaked to the greatest extent, he did not "alarm" the federal security inspectorate and the Lorraine local police department, but worked with Nikolai, who organized the security forces of the factory to catch the ghosts, and directly led the members of the joint emergency response team to "raid" the newspaper.

After more than a year of training and running-in, the joint emergency response detachment, composed of the reconnaissance battalion directly under the 17th National Defense Division, the armed inspectors dispatched by the Security Supervision Department to Lorraine, and the Lorraine police, has become a quasi-special service force with rich experience in counter-infiltration and counter-espionage. In terms of the emergency response mechanism, the state government led by Weiss has also agreed with the garrison, the Ministry of Security and the local police to "act first, report later" if necessary, ensuring the mobility and confidentiality of this special force to the greatest extent.

This time, Weiss dispatched 24 members of the joint emergency response team and went into battle in person to ensure the victory of the first blow. After breakfast, the team set off and arrived in a truck to the neighborhood where the newspaper office was located. The operatives were broken up and approached the front and back doors of the newspaper office. At this point in time, more than a dozen staff members of the newspaper have entered the office one after another, and they have just started their day's work. Prior to this, Weiss asked the tax officer to help him check the situation of the newspaper, learn about the number of employees and the scale of the business, and obtain the structural plan of the building where the newspaper office is located from the construction department, so as to have a more detailed understanding of the target situation. As soon as the appointed time came, they took decisive action and entered the newspaper office through the front and back doors. The newspaper office was stunned to see a group of murderous trench-coat men rushing in, but Weiss didn't bother with them, squinting and walking through the office to the executive's cubicle.

In the special field of vision, a red frame suddenly appeared in one of the compartments, which meant that the people inside were strongly hostile to the sudden intruder outside, and before they could take out their weapons, Weiss broke through the door and unreasonably smashed people to the ground, without having to say hello, and the members of the joint emergency response team who rushed forward stepped forward to tie them up so that they would not use the weapons or poisons they carried with them to end their lives.

It was only when the Joint Emergency Response Unit took full control of the newspaper office and searched the public premises inside and outside that the Lorraine police arrived belatedly. After a surprise interrogation, other relevant personnel of the newspaper did not know the identity and intentions of the two hostile agents, and after the two hostile personnel were captured, Weiss and the emergency response team escorted them directly to the interrogation room of the Federal Security Inspectorate in Mason, where they were interrogated in a professional manner. Both attempted suicide during interrogation, but they were unable to do so because of federal preparations.

After two days and two nights of high-pressure interrogation, the two men confessed some information one after another. They are just a subordinate information relay station, and after extracting useful information, it is hand-delivered to another company in Mason, which is qualified to conduct international trade. Although it is not known for certain how they transmitted the information, their cargo was regularly linked to the Kingdom of Basel through the air port of Belakaser, and it is speculated that they probably used this line to transmit information. After the fall of the newspaper, a subordinate stronghold, two days later, when Weiss followed this clue and attacked the foreign trade enterprise again, they found that the building was empty, and the relevant personnel did not know what to do. Although they immediately took control of the Belakasser, they still did not find any trace of these people, and it is likely that they were evacuated on the spot, changed their identities and hid themselves, rather than trying to cross the border.

On the other hand, Nikolai's operation to clean up the ghosts was also successful, and they captured the engineer. Although the man also tried to end his own life, the methods were unprofessional and failed despite the vigilance of the security personnel. After review, the engineer poured beans into a bamboo tube and explained everything before and after. The reason why he became a low-level intelligence agent of the Normans was that the Normans abducted his family during the war, and in the official management files of the Federation, his family had unfortunately died in the war, and there were relevant certificates such as the time of death at the burial site, etc., which did not seem to be suspicious, but they were still alive, but they were taken away by the Normans. For the safety of his family, the engineer had to cooperate with the Normans to gather federal intelligence. During these years, he also received some funds from the Normans and used them to rebuild his family. His contact with the Normans was a one-line contact, and the only point of contact was the newspaper that had been raided and uprooted. Now that the line is broken, he has basically lost his effect. Although he was very worried about the safety of his family, he knew the depth of his crimes, and frankly stated that he was willing to unconditionally cooperate with the federal authorities and accept the corresponding punishment, and only hoped that his newly formed family would not be implicated.

This round of competition, with the removal of a nail and two contact points planted by the Normans, was not fruitful, but a good start. Then, taking advantage of the passage of the local retirement insurance premium bill by the Lorraine parliament, Weiss launched a population registration and employment history screening campaign in Lorraine. This is similar in nature to census registrations, which are nominally designed to provide a basis for calculating the individual base of retirement insurance contributions, but in practice require everyone working in Lorraine to register the relevant information clearly and to be well documented. In fact, it is difficult to find out who is lurking in the Normans through this census of information, because a lot of information has been through the war—the older ones have been through two wars, and many of the experiences have no witnesses, but this is a tactic of psychological warfare. Weiss deliberately let out the news that a number of suspicious persons had been screened during the registration process and handed over to the Federal Security Inspectorate. After the permanent population of the country is determined through this registration, the police department is asked to register and control the floating population in order to grasp the movements of these migrants.

Given that the Bela Casser airport has become an important window for information exchange, where information is gathered, both overt and covert, and with the federal security services already present, Weiss mobilized Lorraine's police and educational resources to form a semi-official information technology team. The team, which is partially covered by the local government of Lorraine through security funds, mainly screens and monitors radio communications, manifests, etc. The team is relatively fixed, and is regularly rotated at the Belakaser airport on a rotational basis, monitoring communications and following the management to inspect the cargo. Although at the beginning, they did not have any "achievements" for a long time, but the power of scientific thinking and science and technology gradually emerged over time, mathematicians through regular statistical analysis, pointed out the need to focus on the frequency of communication and the batch of goods, literary and historical experts helped the federal security inspectorate to deduce and decipher the commercial code, and in the failure to continue to try, and finally find the first and then the second, the third clue, and then by the Lorraine police department or the joint emergency team to follow these clues to carry out operations, Uncover the various inner demons lurking in Lorraine, making it more and more difficult for those with bad intentions to move forward in Lorraine.
