Holding a small flashlight like a lighter, Chen Fuyi and the two carefully searched for useful information in the room, and after looking through it and finding nothing, they prepared to move to other rooms.

At this time, it was late at night, and there was no one in the complex, so the two of them could open the door and enter the corridor with confidence, but they were still very careful, for fear of making too much movement and alarming the Japanese soldiers guarding outside.

The corridor was narrow and slender, with more than a dozen offices in between, and in order to speed up the search, the two men split up and prepared to search the entire complex.

Searching one by one, except for some daily documents, nothing useful has been found, Chen Fuyi can't help but be a little annoyed, don't spend so much energy this time, but get nothing.

In the end, I had to put all my hopes in the headquarters office of the complex building, and if there was really any secret in Unit 731, it should be placed in the headquarters office.

When they entered the headquarters office, the two did not enter at the same time, but left one person outside to let out the wind, and at this last moment, there should be no mistakes.

After Gu Qiangjun stayed to let off steam, Chen Fuyi entered the headquarters office alone, compared with the ordinary office, the headquarters office is much more spacious, not only has a complete set of reception tables and chairs, but also a nanmu soft bed for rest behind the screen.

There is a set of desks by the window, presumably the commander's daily office, not only a lot of documents and books are piled up on the desk, but also a desk lamp and a photo frame, the photo in the frame is a family photo, a Japanese lieutenant general holding his wife and children, looking like a happy family.

Seeing the family in the photo full of happy smiles, Chen Fuyi felt angry, these bitches still know the family affection of family reunion? It's just a joke.

If it weren't for Chen Fuyi's visit to investigate intelligence this time, he would have destroyed the family portrait on his desk.

Suppressing the anger in his heart, Chen Fuyi quickly searched. Carefully search for any suspicious documents.

After some searching, Chen Fuyi finally found information about the establishment of Unit 731, but it was still only some superficial information, which made Chen Fuyi a little foggy after reading it.

According to the data, the full name of Unit 731 is "The 731st Epidemic Prevention and Water Supply Unit of the Japanese Kwantung Army in Manchuria", but a water supply unit has eight departments, the first department is responsible for research, the second department is responsible for experiments, the third department is responsible for manufacturing, and the fourth department is responsible for production. The fifth department is the General Affairs Department, the sixth department is responsible for training and education, the seventh department is responsible for the supply of materials, and the eighth department is responsible for diagnosis and treatment.

Chen Fuyi really can't imagine that an epidemic prevention and water supply unit needs so many departments, and each department is divided into categories and has its own exclusive direction, like a huge military organization.

What made Chen Fuyi even more concerned was that the commander who coordinated Unit 731 turned out to be a lieutenant general. His name is Shiro Ishii, and the information shows that he graduated from the Faculty of Medicine of the Imperial University, and is a well-known military doctor in the army, with a lot of medical experience.

Such a high-level talent. It is really unbelievable that he went to the epidemic prevention and water supply unit to be the commander.

What Chen Fuyi didn't expect was that there was more than one general in Unit 731, the first minister, Judi. The fourth minister, Kawashima, and the seventh minister, Otani, all three have the rank of major general. Most of the ministers of the other departments are also Dazuo and Zhongsa, and their military ranks are frighteningly high.

A small epidemic prevention and water supply unit has concentrated so many high-ranking figures, to say that there is no cat, Chen Fuyi did not believe it, and he found out today that Unit 731 secretly brought the captured Chinese to the station, although I don't know what it wants to do, but it will certainly not be a good thing.

After learning about the composition of Unit 731, Chen Fuyi began to look for other useful information, but unfortunately, there was nothing of great value in addition, so he had no choice but to quit.

However, before leaving, Chen Fuyi left some souvenirs for Shiro Ishii, which were some things he had newly learned in the Security Bureau when he was still in the Northwest Soviet District, although he didn't know how those things were made, but as long as he knew how to use them.

Speaking of which, when he saw these things for the first time, Chen Fuyi was shocked for a long time, no matter how rich his imagination was, he couldn't imagine that the bugging device could be as small as a single button, if he hadn't understood it in advance, he wouldn't have thought that it would be a bugging device.

In terms of size, the bug is not only too small to be believed, but more importantly, its transmission distance is much stronger than what was used before, and the sound quality is very clear, as if talking next to it, without that special electronic noise.

If the small bugging device surprised Chen Fuyi, another probe camera made Chen Fuyi shocked, Shanghai Beach had a movie a long time ago, and Chen Fuyi also came into contact because of his interest and knew what the movie was all about.

But when he saw the probe camera, Chen Fuyi was still taken aback, he couldn't imagine that the camera could be as small as a needle, and what made him even more unbelievable was that the picture captured by the probe camera was not only clear without a trace of impurities, but also an unprecedented color picture, far from being comparable to black and white movies.

If, according to Mr. Li Keji, such cameras will be installed in all corners of the city in the future, then there is no need to be afraid of bad actors doing evil in the city, because no matter where the bad guys commit crimes, they will be recorded by the cameras, so that they will not need to spend a lot of time to investigate as before, and they may not be able to catch people in the end.

It was hard for Chen Fuyi to imagine what kind of society it was, but in Wuqi Town in the northwest, he had already seen it once.

Since the country was full of spies at this time, in order to ensure the safety of the Party Central Committee, the Security Bureau first built the first all-round surveillance system in Wuqi Town.

He never thought that a small probe camera could gather all the situation in Wuqi Town into one office, and a few people could fully control everything in a small town.

Now it is rare to visit the headquarters of Unit 731, so naturally I have to leave some souvenirs to say that I have been here. What's more, he needs to get more from Shiro Ishii, and bugging and cameras are the best tools to get intelligence.

Since preparing to infiltrate the 731 unit station, Chen Fuyi has prepared these things before, and at this time he only needs to install them according to the steps he has trained, although his methods are still a little green, but the small and delicate bugs and cameras are very well concealed, if you don't understand, the Japanese army at this time can't find it at all.

After installing the bugs and cameras, Chen Fuyi left Shiro Ishii's office, glad that no one had bothered him.

After meeting with Gu Qiangjun, who was in charge of releasing the wind outside the door, the two prepared to return the same way, although there was still a lot of time at this time, but the energy of the two was limited after all, and they could not work endlessly like Li Keji.

As a good intelligence officer, it is also a compulsory course for them to keep their energy full at all times, and only by maintaining a good physical condition can they accomplish tasks that ordinary people simply cannot do.

Unless it is a time when the intelligence is important and must be solved as soon as possible, a good intelligence officer rarely takes risks doing things that he is not sure of.

As the night deepened, even if the Japanese army was disciplined, it was not only a little lax at this time, but also the reputation of Unit 731 was not obvious, and there were no strong enemies in the northeast.

Because of this situation, Chen Fuyi and the others went back much more easily than when they came out, and they returned to the temporary warehouse without any thrill.

After returning to the temporary warehouse, the comrades all gathered around and eagerly asked the two what they had discovered, since they guessed that the "experimental equipment" in the wooden box might be their own compatriots, they could not sleep well all night, and they were worried about the atrocities of the Japanese army.

Chen Fuyi understood the comrades' worries, first comforted them with kind words, and then said slowly: "Comrades guessed right, the so-called 'experimental equipment' of the Japanese army is our compatriots, and Comrade Qiang Jun and I found that they were all detained by the Japanese army in a prison, but the prison was heavily guarded, and there was only one entrance and exit, and it was impossible to get close at all, so I and Comrade Qiang Jun didn't know much about the follow-up situation." ”

"Why are the little devils arresting so many people? Based on four people in a box, there must be at least one hundred and sixty people, and it's not just the batch we helped transport. Ay...... I knew that the box was full of our compatriots, so I wouldn't have come to help with this. ”

Hearing a little complaint from the comrades, Chen Fuyi comforted him again: "I understand the feelings of the comrades, if I understand what the so-called 'experimental equipment' is, I will not help Nakata Boy." It's just that comrades, let's not forget, what is the purpose of our trip? It's not a deliberate attempt to curry favor with the Nakata kid, our purpose is to probe this secret location of the little devil. ”

"So what did you get out of it this time?"

"It's not a big gain, but it's not nothing." Chen Fuyi said with a smile, and then told his comrades about his findings.

After listening to what Chen Fuyi said, everyone was as puzzled as Chen Fuyi, and there were big question marks in their hearts.

Even if they don't know much about the sequence of the Japanese army, they also understand that the epidemic prevention and water supply unit only belongs to the logistics force, mainly focusing on epidemic prevention and water supply to the troops, why is such an ordinary logistics unit so many officers with high military ranks, and even the commander of the unit has reached the rank of lieutenant general, which is equivalent to the high position of a division commander.
