There are eight lesbians in the Investigative Intelligence Group. They were arranged to live in a house together, and a team leader was appointed. The rest of the male team members were divided into two groups, each electing a team leader, and they were all under the command of Dabao for the time being.

Before Yu Dabao, he was a company-level cadre in the border region and had excellent military and political qualities. For the time being, these team members don't know anything about the situation, so Tong Chuan and Yu Dabao take turns in batches to familiarize them with the surrounding situation. Usually men and women are matched, and they spent several days on the periphery of the fortress and in the workshops and farms, and figured out the conditions and layout of the three strongholds.

When there is no action, they will set up a shift schedule to monitor the three locations. One is to spy on the outside, and the other is to spy on the inside. Each of the three places has its own internal cadre constraints, and they do not interfere. But as long as someone who shouldn't come out comes out, these scouts will do their best to check and investigate.

Theoretically, these people have been screened through layers of screens, and it is unlikely that there will be problems in the first place. Pu Su is afraid that some people are ready to act after arriving in Shanghai, and they can't control themselves, so they make some stupid mistakes.

These team members first familiarized them with the French Concession before letting them go out and get acquainted with the situation in the Public Concession and even in Huxi and Hongkou. He stipulated that there must be two groups of three at a time, echoing each other on foot and by rickshaw, and the two groups were also covering each other under mutual constraints.

For this reason, he asked Lao Ren to apply for five rickshaw licenses. Five rickshaws were brought from the car dealership, and the investigators took turns to act as rickshaw drivers, and every time they went out, they did not solicit outside work, and only pulled their own team members on the car as a cover.

It is not possible to engage in reconnaissance, not be familiar with the road conditions, and not be able to make full use of the terrain. Especially in Shanghai, there are many alleys and alleys, and many streets are not regular.

If everyone has a good level of knowledge of the road as a rickshaw driver, then they really know something about the city. That's when they come into play.

The remaining 20 special combat personnel train in the small courtyard on weekdays. Pu Su gave them a full set of equipment, including the nightwalk and the Skull Breaker. Now they have a lot of uniforms of various models in stock in the warehouse, which were made by the Belarusian women of the community after the fortress was built. Sasha's father placed the workshop directly in the fortress, and the shop on Xiafei Road had only been sampled and measured, and it had simply become a place for business reception.

If there is an operation in the future in which the White Russians cannot participate, relying on the more than 50 fighters on his current side will be enough to cope with a battle of moderate intensity. It really doesn't work, and people can be drawn from the farm at any time, and the so-called honest farmers who seem to outsiders are all qualified soldiers who have undergone rigorous military training.

Pu Su added up the manpower on both sides and calculated it, and there were already two reinforced companies. In today's Shanghai, it is enough to fight head-on with the garrisons of the two concessions. Of course, the lack of heavy weapons is that they can only defend.

Fortunately, if the fortress is surrounded now, attention is on the inside, and in the case of negligence on the outside, the soldiers on this side of the house and the manpower of the farm can carry out a surprise attack from the outside, and the people inside will take advantage of the situation to surprise out, and they can easily form a two-sided attack on the incoming enemy, turning the situation and catching them off guard.

After three days, the situation on the farm side was basically stable. The engineer at the workshop decided on a plan for the construction of a hidden dock after surveying, and Pu Su immediately agreed to the plan after reading it.

The new plan is to dig down the factory that was acquired next door and dig inside. After draining the water from the river, a long and narrow channel is formed in the factory. It was designed by a German-led engineer who worked at the Meyer shipyard, Germany's largest indoor shipyard at the time.

This type of dock design is usually used in the construction of small ships and submarines to facilitate the launching of water, and they are naturally very suitable for one-time running purposes. After all, the freighter is easy not to start, and once it starts, it is an emergency, which means that all the staff are evacuated, and it is unlikely that they will come back in the future.

This scheme makes the best use of the existing conditions, and there are ready-made factories around and on the roof, and only this one civil project needs to be excavated down. Of course, after fixing the freighter, it is necessary to build platforms on both sides, which is a matter of slow work and meticulous work, and the current priority is to solve the problem. After the dockyard is built, first get the ship in, solve the problems that are not there now, and then slowly improve it.

At the same time, for the opposite bank is their own farm, the engineer also proposed to lay a hidden rope in the river, and when necessary, both sides can turn the winch to pull the boat, so as to facilitate the traffic between the two sides. In peacetime, whether it is transporting goods at night, the evacuation and reinforcement of personnel in wartime play a very important role.

When necessary, the winch tightens the rope, which immediately changes from a relaxed state to a tight state, and rises from the bottom to become a link between the two shores. Such a secret cable plan can be put into three ways and can work quickly. The winch is set on both sides, and which side has a situation can be started immediately.

Pu Su is very satisfied with the overall plan. There is a specialization in the art industry. The arrival of these professionals has solved many practical problems, far beyond his original expectations. And the workload was much smaller than he expected. Because the surrounding area is their own people, so the engineer proposed not to excavate the periphery along the river, only in the factory interior construction, can carry out a small amount of explosives blasting, the sound in the closed environment is limited, the efficiency is very large, and this piece is a factory, some movement will not attract attention. Wait until the depth and width of the interior are sufficient, and finally dig and divert water.

This time they brought several loads of high explosives, all homemade by the chemical engineers of the border area. Although the power is slightly inferior to that of "Black Sorkin", it also greatly exceeds the intensity of TNT. Pu Su was going to wait until he had finished the few things in front of him, and he would use this batch of explosives to make various explosive devices. He now has weapons experts, as long as there are materials and reasonable ideas, they can make it as needed.

That night, the truck began to sort, and Lao Ren dropped two more trucks from the French Concession, driven by the White Russians, and pulled all the laborers to the workshop, where tools were distributed for secret construction. The special combat team members and reconnaissance team members, including the farm laborers on the other side, all started the excavation work in the closed factory building. The soil was pulled by a dinghy to the opposite farm and built into an artificial mound.

After planting grass seeds and fruit trees, what appears to be a natural soil slope is actually a commanding height on the plain, on which a common farmer's guard shack is built, and people are stationed on it day and night to observe the surrounding area. Because it is a gentle area, this observation point has a very large observation range.

Li Wenjuan's radio firm is already in preparation, and all kinds of equipment are being shipped to Shanghai by sea. When the various parts arrived, several high-power radio stations would be set up, and the plan was to place one on the farm with a telegraph operator.

Liaison is the number one priority, and in any case, this side is behind enemy lines. They will be very passive when they are separated from the contact with the superiors in the base area, and the formation of three-dimensional air communication is the safest means.

If the situation continues to deteriorate in the future, to the point where Pu Su predicted, at least he has a few channels to report. The one Li Wenjuan now has in her hands, the Voice of Russia of the Russian Chamber of Commerce, and one in the farm. In addition, there is also a Ma Dafu who has completely disappeared from everyone's eyes, and there is a low-power radio station in the clinic on Hagrid Road.

When necessary, he can rotate the sending and receiving, so that the enemy's wireless detection cannot grasp the law and frequency of the call sign, and the directional detection is at a loss. For example, today at this time period, the range is detected in Lafayd Road, and tomorrow when I come to squat to further determine the range, the signal disappears completely, but a new frequency appears in the other direction, and after running to squatting there, I find an unfamiliar ......

He didn't know how capable the original "lighthouse" was, and that it had been able to operate in Shanghai for many years without being cracked, and that he should have a unique set of experience behind enemy lines. But he is confident that the system he is currently building has put into practice most of the knowledge and experience he has learned in agent intelligence, and it will definitely be an efficient organization after it is formed.

The superiors spared no effort to support him, and everything they could give was provided to themselves, and the elites and experts from the border area were sent. Presumably, I made a big determination to build another system in the heart of Shanghai. Although I haven't made it clear to him until now, I don't want to put too much pressure on him, but judging from the above actions, this intention is already very obvious.

He knew in his heart that the "lighthouse" was completely different from his situation. The role there is scheduling, and it plays the role of uploading, issuing and coordinating. He was the steward of all the underground workers in Shanghai before, and he was also the support of every agent. The first thing that all comrades think of when they encounter a situation in Shanghai is to contact her for help and advice.

Because of this, every agent who contacts her is not her direct manager, nor is it her direct subordinate. Therefore, it is inevitable that there will be a mixture of fish and dragons among those people, and Pu Su will never rule out that there are renegades among those people.

In fact, this alone is not clear to the "lighthouse" and its superiors? However, the "lighthouse" has a heavy task, lacks skills, and has no ability to screen, and the superiors are beyond the reach of the whip.

Therefore, Pu Su's additional tasks include screening and purging, but in fact, he is even suspicious of the "lighthouse". Now the focus is on giving priority to the development of himself, and after he has a certain degree of self-protection ability, he will now have no shortage of manpower, and at that time, he will arrange a detailed investigation according to the list of comrades lurking in Shanghai.

The most hated thing by all intelligence officers is the mole. Senior Gu Ji was almost planted in the hands of a traitor, and his own life was also hanging by a thread not long ago. This is also the most important reason why he strictly supervises this group of comrades internally.

Once there are moths inside, no matter how good the external skills are, they will be vulnerable. For example, the structure and defense of the fortress, the hidden dock of the workshop, the actual nature of the farm, no matter how secret these places are built, as long as someone inside is betrayed, it will basically be broken with a single stab.

This strategy behind enemy lines, which is loose inside and tight outside, is not a short-term act, but a work that needs to be carried out for a long time here. Whenever anyone is found to be wrong, the members of the investigation team will report it, and the political work cadres will immediately investigate it. In serious cases, they will control their movements and be sent back to their base areas when appropriate.

It's an iron rule. Anyone knows what to do and what is likely to cause misunderstanding, so don't even think about it.

If there are comrades, they can adapt to the difficult conditions in the border areas. When I arrived in Shanghai, I had good food and drink every day, and everything was arranged by logistics, but I was emotional, and my thoughts were dissatisfied...... Then I'm sorry, after the political work cadres have talked, they can immediately restrict their actions according to the situation, wait to be sent back to the base area, and continue to gnaw at their nest heads and fight head-on with the Japanese invaders there.

I don't have any thoughts when I live a hard life every day, but once I live a good life, I think about it? Is there such a person? There really is! And not a few! Human nature is like that, it seems difficult to understand, but it actually happens very naturally.

The atmosphere in the border area is a frontal battlefield. Survival is the main thing, and I can't think of anything else. The people around him, including the chief, are treated similarly, and there is nothing to think about. When you arrive in Shanghai, first of all, you are prone to slackness in your thinking, and you will have the illusion of traveling on a business trip. Treating the time spent here as a short-term act, and not taking Pu Su and other temporary cadres seriously, in their opinion, compared to the cadres and superiors in the base area, Pu Su and they lacked some authority.

In addition, Shanghai itself is a modern metropolis, full of colorful and bizarre. Even in the farm, you can see the glittering neon of the ten-mile ocean field when you climb to the heights, which exudes a mysterious and seductive light for some people. The city is full of teases and teasing, and it is a serious test for many.

Even the special combat personnel and the reconnaissance group kept them in a state of simultaneous dispatch of the two groups at all times, forming a situation of mutual restraint and containment, and in other words, it was a response and cover. It's also a dead rule that you can't go out alone, and you can't act alone without permission. There are two groups, there are many people, even if most of them want to break the rules, there are always one or two who abide by the rules, so that others dare not act rashly.

Because he understands human nature, he never intends to test it. There is no need for that kind of test, and the outcome is often full of holes. No matter what great faith these comrades have, they are first and foremost living people. The best thing to do is to rely on the rules to enforce and maintain, including himself.
