Ning Zhiheng's words stunned Chen Xiang. To be honest, although he knew some of the situations of microfilm, he didn't know much about it. Now he heard the instructions from the audience and couldn't help but hesitate for a moment.

Ning Zhiheng naturally had his own considerations. In fact, the moment he received the news, he had already made some judgments. As far as he knew, the technical information of G-type engines and aviation torpedoes could be said to be long-lasting and full of various drawings and data. It would be absolutely impossible to record them using paper and carry out ocean transportation.

Therefore, he believes that Germany must have adopted the most commonly used microscopic technology in the international intelligence community at present, and took all the data into small films. This is the safest and safest method.

This microscopic technology is actually not a new technology. It has been used in the last century. In 1853, the UK could already shoot the entire Times into a film with a diameter of one sixth of a centimeter.

During the French-Prussian War in 1870, the French began to invest this technology in military purposes, reducing hundreds of thousands of confidential documents and instructions into tiny film for transportation and transmission.

More than 80 years have passed, and to this day, microscopic technology has made great progress and has made great progress in storage volume and stability.

This technology has been popularized in many fields, especially in the storage of data. The advantages of microscopic technology are fully revealed. Not only can the vast amount of data be reduced to a film the size of a stamp, but the microscopic film is also stable and not suitable for damage, and has strong storage security, especially strong fidelity for the original.

Now Western countries with advanced technology are also using this technology. Units such as large banks, libraries, newspapers and others use it to store information. Now, the British are afraid that German bombing will damage the precious collection of books in the British Museum, so they use this technology to shoot the entire museum's books. The military intelligence departments naturally see the benefits, so they are widely used in intelligence and spy wars.

However, this technology also has certain limitations. Microfilm not only requires high-resolution and high-resolution technology equipment to shoot, but even read, special instruments are required, such as dedicated slide projectors, projection equipment, etc., and even copying equipment is extremely rare.

However, because China is relatively backward in science and technology, it has never had much contact with microscopic technology.

It is said that the year before the Battle of Shanghai, the United States had funded a set of microscopic equipment in the Peking Library, but it was taken away by the Japanese military after the war.

As far as Ning Zhiheng knows, it was at the headquarters of the Military Intelligence Bureau that he had recently purchased a set of microscopic shooting equipment and reading equipment, as well as dedicated copying equipment from the United States. As for other confidentiality departments, it seems that they are not equipped at all.

Even in Shanghai, Ning Zhiheng has never heard of such high-end equipment. I guess even if it has it, it will definitely be in the hands of the Japanese intelligence department.

Hong Kong is an international port city occupied by the UK, and it is possible to have such equipment.

Ning Zhiheng knew that even if he could seize the microfilm of the drawings, he still needed to find such supporting microfilm equipment, especially a copy machine, to copy a copy of the film so that it could be handed over to the Military Affairs Bureau and the underground party organization, so he wanted Chen Xiang to investigate and see if such professional equipment could be found in Hong Kong.

Ning Zhiheng then instructed: "You should focus on searching units such as banks, libraries, newspapers, and even film companies, and give me news as soon as possible. If not, spend a lot of money to go to the United States to purchase a set of equipment. We will use such equipment in the future."

"Yes, I'll investigate immediately and report to you as soon as possible!" Chen Xiang nodded quickly.

At night, two young men were walking out of a tenement building near the Hong Kong Pier.

One of the men walked in front, with a slightly taller figure, a thin body, an ordinary face, wearing a suit, but with an open collar, looking out of place. At this time, he spat hard and cursed: "This guy, Rotten Guidong, is really not a good thing. He chases behind his butt every day, but he doesn't want to give it to him, but who is he holding a grimace to show him? Bah..."

Behind him was another man, who was shorter, but his shoulders were wide and his back was thick, and his facial features were quite strong. He looked at his companion squintedly and persuaded him: "Feizai, we are so angry these days, so don't go to the gambling table of the Rotten Guidong again. I heard his words today, it seems that he was going to come true. Maybe he will deal with you. Be careful."

Feizai curled his mouth and said disapprovingly: "Aren, don't worry, we are not without a hall. He also wants to give Brother Bing some face. There must be a way before the car arrives at the mountain. It's still early. Let's find a place to have a supper, take a few sips before going back!"

The two of them walked together, intending to find a place to have a few glasses of wine, but after not far away, two figures flashed out in front of them, and one of the men said, "Feizai, Aren, Brother Bing wants to see you!"

The two of them looked at each other. The boss of their hall sent someone to find him. He did not dare to neglect him. He quickly nodded and agreed and followed the people along the way. Soon, they came to a courtyard.

This is the residence of Brother Bing, the boss of "Heshengtang". Heshengtang is a local gang in Hong Kong. The main members are dock workers and nearby marketists. They are relatively strong. Feizai and Aren are both members of Heshengtang.

Several people came to the hall. Brother Bing had been waiting here for a long time. Seeing the two people coming in, he frowned and asked directly: "Feizai, you have been doing well these days. When will you hand over that batch of goods to me?"

Feizai hurriedly explained: "Boss, the goods are all pressed in the bottom warehouse. Now the ship is being held by the British and everyone is driven down. We can't go back at all. After a while, the wind will pass, we can't go back to pick up the goods."

It turned out that Feizai and Ah Ren were also crew members of the Notting passenger ship. Although the Notting passenger ship is a passenger ship of the French shipping company, it has been running Asian routes for many years and has many Asian passengers. Due to language and various reasons, it has also recruited some Asian crew members. Among the crew members on the Notting passenger ship, most of them are French, and some are Singaporeans and Hong Kong people hired.

Feizai and Aren are the crew members of the Xiaotai, the waiters responsible for receiving guests. The crew is a high-risk and high-income industry. In addition to having a generous salary, it is mainly due to professional reasons that they can carry smuggled items at work to make profits. This situation is already the norm. Whether it is European crew members or Asian crew members, most of their income comes from this.

Feizai and Ah Ren are no exception. Every time they travel around, they carry some goods with high smuggling value. This time they return to Hong Kong. They bring back a lot of precious medicines and precious perfumes from Europe, but unexpectedly, the Notting was detained by the British garrison as soon as they arrived at the port, and even the people were driven off the ship.

I was caught in a flash, and they had no choice but to wait, but most of the goods transported were invested by Brother Bing, and they were only responsible for transportation. In this way, Brother Bing was the one who was most anxious, so they called the two of them to ask about the situation.

When Brother Bing heard Feizai's explanation, he did not ask about the goods anymore. He waved his hand and said, "I won't mention the goods matter for now. I'll ask you, what happened on the Notting passenger ship? I heard that someone died, and the noise was quite a bit. You can tell me carefully."

Originally asking about this, Feizai and Aren looked at each other, Feizai immediately cheered up, with a mysterious expression on his face, and said, "Boss, you know this too, then I'll tell you, this is the case. Just when the ship was about to arrive at the port, several Japanese suddenly found their companions dead in the room..."

Feizai and Aren were both waiters present at the time, and they knew the situation very well. They quickly described it. Feizai finally said: "In this way, the captain called the police on the radio. As soon as he entered the port, someone got on the boat, but it was not the police, but the British garrison. As a result, the Japanese were taken away. We were also driven off the boat with the passengers. The boat was detained in the dock. Later, there were British guards, and we have not yet gone back."

Brother Bing didn't say anything, but listened carefully to Feizai's narrative, and after a long time, he asked, "Who do you think killed this person?"

Feizai shook her head and said, "It's not clear. This Japanese man is named Yanagawa. He was very close to a foreign woman shortly after he got on the boat. The two of them were often together, but she did not show up when something happened. Later, when the garrison boarded the boat, she came forward. I think it was probably related to this foreign woman."

At this time, Aren, who was standing beside him, said, "When I first got on the boat, this woman was still the same person, but later, I found that she had met a white man secretly. After saying a few words, she hurriedly separated. She felt something was wrong. Later, as soon as the matter came out, she stood up. The captain and the garrison were still following her command. Boss, I guess it was her who did it!"

But their words did not satisfy Brother Bing, and then asked, "There are no other suspicious people except her?"

Feizai and Aren couldn't help but look at Brother Bing in confusion when they heard this, and shook their heads.

Brother Bing no longer plays puzzles. He needs these two people to inquire about the news and must give them some clues.

"That's right, this Japanese man named Yanagawa carried a very important thing on his body, but as long as he died, the things disappeared. As for what the specific good thing was, I don't know. The foreign girl you mentioned should be a British, but now that the British have made such a big noise, they may not have done it. In short, this thing is very expensive, and even Mr. Yue also made a statement. If he could find this thing, he would be willing to pay a lot of money.

So, after you go back, think about it, recall the situation on the ship, and see what clues there are, such as suspicious passengers, or the crew members around you. In short, if we can find this thing, we will make a fortune and have snacks. If you have any news, please inform me immediately!”

“Yes, yes!”

"I understand, boss!"

The two of them nodded and agreed immediately after hearing this.
