Be! The two men stepped forward and replied. Then they turned around, discussed with each other in the warehouse, and then picked up.

First of all, they looked at a few mines and found that the magnetic device was intact, and they were directly carried into the car. Speaking of which, there are always people who misunderstand the size of the mine, thinking that it is quite small.

In fact, this thing is small because compared to ships, the mines look very small. Actually? If a person stands in front of a mine, he can see that this thing is much larger than the largest fitness yoga ball in later generations, although it can float in the water, but the weight is not light at all, and it is dead and sinking. If a person wants to lift, it is almost impossible. Moreover, the mines are covered in iron spikes that look like hedgehogs, which is their unique triggering device.

Once a ship passes near the mine, the magnetism of the mine itself seems to be "attracted" towards the ship. Finally attached directly to the ship. At this time, these hedgehog-like probes will also be touched, and in this way, the charge department inside will also be activated. Eventually explode, destroying the ship.

Of course, the mines in this are good, but they are not scrapped products, in fact, if this thing is really scrapped, it will be carefully pulled to the field or uninhabited land to detonate, otherwise it is too dangerous.

Jiang Bin and Du Shengli were also cautious, and after careful inspection, they confirmed that they were in a "closed" state, so they let people carry the mines out to load the car, and finally a total of about 12 mines were installed. Then a batch of professional maintenance and inspection tools was pulled away. That's the end of it.

Naturally, this matter should be as secret as possible, and a secret place to ensure security is needed first. However, it was very simple for the Security Bureau, and it was placed directly in an abandoned quarry on the southwestern outskirts. After a simple makeover, the wires were pulled, the lighting was installed, and other equipment was installed. And a platoon of internal security guards from the Security Bureau was transferred.

Fan Keqin watched as the two bomb experts carefully dismantled the mine, took out the charge part of it, studied it carefully, and finally found that the explosives loaded with the mine were TNT. This may be due to the fact that TNT is so waterproof and powerful.

Confirming this, Fan Keqin looked down and said, "Can this thing be modified more powerful?" ”

Jiang Bin nodded affirmatively and said, "Yes, the Americans' mines have a depth fixing device, and if I and Shengli expand the charge, they can only occupy a certain amount of snorkeling cabins." However, the lowly position feels that if it is occupied, it will be occupied, and it doesn't matter. ”

Fan Keqin has been watching from the sidelines, but he understands the principle of this thing, a bit like a submarine. If you want to dive, you will fill the tank with water. This will dive into the sea, and the more water you fill, the deeper you dive. On the other hand, if you want to float, start draining, and once you have completely emptied the filling tank, it will float on the water.

If a mine is densely packed on the water, it is easy to see with the naked eye. This is a long distance, and if you detonate it with fire, you can rule out the danger.

In order to be able to work, some time after the invention of mines, there was a depth fixing system. For example, in a waterway, if you lay nearly 100 mines near the mouth of the sea, they must be high and low in an orderly manner, with different depths. In this way, there are on the surface of the water, two meters below the water, and three or five meters below the water, which will form a huge fog trap, which can confuse the other party and increase the danger of removing mines. It is not even possible to demine. Then the waterway is blocked.

Moreover, the cost of weapons and ammunition such as mines and torpedoes is much cheaper than that of a ship. Ships are usually seriously injured or sunk when they are fired, but even if they don't work, mines don't have much money. It doesn't hurt at all. This is also the reason why millions or tens of millions of mines were frantically thrown into the sea by both sides of the war during World War II. Even these mines had not been completely cleared at the moment before Fan Keqin crossed.

Fan Keqin said: "You two are experts, and everything is up to you when it comes to bombs." ”

"Thank you for your trust." After the two of them finished speaking, they talked to Fan Keqin about their thoughts again. What does that mean? That is, didn't Ma Chunliang say that it is best to explode about three meters below the waterline, so that is to say, the mine is underwater. And this mine itself has a depth fixing device, if it is adjusted to three meters, it will float about three meters underwater and float with the tide.

Keep in mind, however, that this is a standard charge, if the charge is increased and the water tank is occupied, say three times the charge. Then you don't need to set the depth, throw it into the water, and the mine will also snorkel two meters below the surface. At this time, if the fixed depth is adjusted to three meters, then the mine will snorkel to five meters. It's not the three meters that the mine depth shows.

However, this problem is not big, Jiang Bin and the two of them calculated the amount of charge, and connected it with a sealed detonator, so that in addition to the original charge department, four of the water injection tanks were also loaded into TNT. It was then transported by cart to the river, where its depth was measured......

Fan Keqin couldn't always be here, and after returning to the Security Bureau, he asked Zhuang Xiaoman to immediately notify the Investigation Department and the Field Service Corps, and all the field staff above the captain went to the conference room on the first floor for a meeting.

Fan Keqin began to study the port situation in Guangzhou again. Speaking of the port of Guangzhou, it is now in the hands of the Japanese, but Fan Keqin has been there before. There is field experience, as well as information support from current investigators from the Military Command and Security Service. What Fan Keqin has to do is that as soon as the little Japanese ship enters the port, then no matter which pier it docks, he must have a complete customized attack plan, not to say, I customized the No. 1 pier, but the other party docked at the No. 2, then I can't help it.

What is best effort? What Fan Keqin does is called his best effort, everything he can think of, all the details are planned. Therefore, as long as the port in Guangzhou can dock a wharf with a displacement of more than 10,000 tons, he wants to customize a set of action plans for each one, which is called the best effort!

About half an hour later, Zhuang Xiaoman came over and reminded him that everyone had arrived. So Fan Keqin took the chick directly out of his office and came to the conference room.

Standing in front of his chair, he looked at Lao Qi, Ji Gang, Tong Fei, Hua Zhang, Zhao Debiao and others on both sides. He pressed his hand down and said, "Sit down." Then everyone sat down in unison.
