Diaoyu Dao is located outside the waters of Fujian Province, China. At present, it has become an important topic www.biquge.info of the Sino-Japanese conflict. According to the relevant international laws and regulations, it undoubtedly belongs to the island of China. However, Japan has repeatedly challenged China's bottom line on the issue of the Diaoyu Islands, and the Japanese government has even registered the "Kitakojima" of the four islands near the Diaoyu Islands as state-owned property.

In the face of Japan's aggressive posture, one cannot help but wonder why Japan attaches so much importance to such a small place.

On the surface, Japan's interpretation of its citizens is that the Diaoyu Islands are of great strategic value and play a pivotal role in the issue of marine resources.

But is that really all about Japan's ambitions?

As we all know, the Diaoyu Islands are uninhabited islands. In other words, it does not have the resources of its own, and it is extremely difficult to station an army on it, and all needs need to be transported from the mainland for supplies. In addition, it is extremely small, and it can disappear under the waves at any time as the world warms and the sea level rises. The Japanese seriously considered whether they should build concrete buildings on top of it to prevent this from happening, but they gave up for fear of angering China. Geographically speaking, the Diaoyu Islands are extremely close to China, and in the event of war, the Diaoyu Islands, which are isolated overseas, will not be able to prevent the PLA from landing at all. The distance problem also directly affected the support of the Japanese Navy and Air Force. With the completion of our aircraft carriers, the Japanese Navy is not an opponent, not to mention the struggle for the Diaoyu Islands, and it is extremely difficult to maintain the mainland from the threat of bombing.

So why does Japan still value this small land so much?

It all started with World War II.

At that time, when Germany was increasingly defeated, its fascist militarists were not reconciled. To do this, they set their sights on an ally in the East: Japan.

Although they were well aware that Japan did not have the ability to directly support Germany. But they intended to support Japan in turn. According to their wishful thinking, they would finance Japan's war forces to withstand the American advance. Forcing the United States to transfer troops to the Pacific War, slowing down the offensive in Europe.

To this end, they prepared a large amount of materials and technology to support Japan.

Because the sea was gradually blockaded by the Allies, they chose submarines as a means of transport.

The first Japanese submarine to arrive in Europe was the I-30. It unloaded drawings of 3,300 pounds of mica, 1,452 pounds of shellac and Japanese Type 91 aviation torpedoes to Germany. In turn, 100 million yen worth of industrial diamonds, a complete set of Würzburg ground-based anti-aircraft radars and their drawings, "Zeiss" anti-aircraft artillery commanders and other materials for the war were transported back to Japan.

After that, such submarine transports in Japan and Germany became more and more frequent, and laid the groundwork for the rest of the story.

As the war progressed, the Japanese mainland gradually received threats from the American army. Japan started the idea of using the colonies. In a vain attempt to move the capital to China after the defeat in the "decisive battle at home", and continue to confront the Allies in the vast territory of China. And made serious preparations.

Relocation requires the transfer of materials. At that time, the Japanese sphere of influence was under the threat of Allied bombers, and any warehouse could be attacked. For this, the Japanese made an amazing decision, which was to seal it with cement and sink to the bottom of the sea!

What could be more resistant to Allied bombing than seawater? In a methodical manner, large quantities of war materials, such as coal and rare earths, were sealed up and sunk to the bottom of the sea. In addition, a number of Japanese cultural relics that were scheduled to be moved to China were also properly wrapped and sunk near the Diaoyu Islands.

Seeing this, some people may say, oh, it turns out that there is a treasure buried over there. No wonder......

Is that really all there is to it?

Not really. Those supplies and artifacts. If it falls into the hands of someone or even a certain company, it will be a windfall. However, for an economic power like China and Japan, it is really a drop in the bucket.

The real key is the I-704 submarine that sank near the Diaoyu Islands.

The I-704 submarine is a giant transport submarine built by the Japanese Navy for secret transportation between Japan and Germany. It could transport 100 tons of supplies at a time, and was on a mission to deliver Tiger tanks to Japan. At the end of July 1945, after returning from Germany, it did not return directly to its home port. Instead, he came to the vicinity of the Diaoyu Islands to carry out a secret mission. He sank in an accident due to metal fatigue during underwater operations, and quietly hid at the bottom of the sea for decades.

So, what kind of secrets are hidden in the I-704 submarine?

It turned out that it was transporting strategic materials when Japan and Germany were on the verge of defeat!

As Germany was on the verge of defeat, the Nazi fascists increasingly pinned their hopes on Japan. And no longer keeping secrets, a large number of top-secret materials were shipped to Japan in an attempt to make a comeback. I-704 is on a mission. It is no longer a general material such as rubber, but a strategic material that can affect the country's fortunes.

As we all know, Nazi Germany was very technologically advanced, and put forward such epoch-making products as waverider aircraft and round jet aircraft. Missiles were also created for use in actual combat. It is these scientific documents and drawings that are transported on the I-704.

Hearing this, some people may not think so. I feel that the technology that appeared to be advanced again during World War II. That's not the case today. There is no value at all. Not really!

Because, technology is often about whether it is researched or not, rather than the level of technology.

For example, the level of oil substitution technology is still not high, because oil prices have not been unacceptably high for a long time. Therefore, it is natural that oil substitution technology cannot make progress. Because it didn't work. For example, the steam engine was invented by Westerners in the Roman Empire, but it was never used because of cheap slave labor.

However, we can currently note that oil prices are rising day by day and many wells are facing depletion. And importantly, China is a big country that imports oil, and once it is cut off from oil delivery channels, the consequences are unimaginable!

And the scientific and technical literature loaded on the I-704 is exactly the energy side!

As I said earlier, technology is not about the confines of the times, but about the amount of money you put into it, and oil was not an unattainable thing in Nazi Germany. However, Germany is under siege and does not produce oil itself. Therefore, great efforts have been made on alternative energy sources. Japan was also in a state of poor oil at the end of the war. As a result, the I-704 submarine is carrying a lot of related technology.

Among them, there is a flywheel energy storage device developed by the famous German female scientist Julia Diezer. Clever design,. The Soviet Union once obtained some drawings and applied them in practice, but later abandoned them due to the great development of oil. However, according to the research of Soviet scientists, judging from those drawings, Julia Diezer's design of the flywheel energy storage device is no worse than the huge investment made by the American business community in the future! (The American business community has invested a huge amount of money in R&D to support flywheel energy storage, such as ActivePower, which has received up to $10 million per year from its parent company for several years.) ）。

In China, due to the restrictions of supporting policies, flywheel energy storage has not been given the opportunity to show its strengths. Since the 80s of the last century, flywheel energy storage has only received support from three projects, except for the field of national defense, the total investment of the public is less than 5 million yuan.

It can be said that once the flywheel energy storage device on the I-704 is obtained, it will have a huge role in promoting the application of energy storage in China.

The flywheel energy storage device is not the most valuable scientific document on the I-704. The coal-to-liquids plant developed by German scientist Goz Otto is even more eye-catching.

As mentioned earlier, Germany is an oil-poor country. However, it also produces a lot of coal. As a result, coal-to-oil technology has written a strong mark in the history of technology in Nazi Germany. Half of Germany's oil consumption during World War II came from coal-to-liquid, of which two-thirds of jet fuel aviation gasoline (auger gasoline engines) came from coal-to-liquid, which played a mainstay role.

The situation in our country is similar to that of Germany. Our country has been an oil importer for a long time, but it has a large number of coal mines. In the vast and boundless grasslands of Inner Mongolia, many places directly use forklifts to shovel the ground is coal!

For a country like China, which is an increasing energy importer, coal-to-liquids is a very strategic industry. The temptation to get Nazi Germany's top-of-the-line coal-to-oil technology is self-evident.

And that's just some of the hidden purposes on the I-704.

According to the discoveries of American divers, some mysterious vats are hidden in the wreckage of the I-704. The material of the vat is inert.

What kind of items need inert materials to contain? Radioactive items!

It is reminiscent of the corresponding nuclear weapons programs of Japan and Germany before World War II. It's clear what is inside: nuclear materials!

The two fascist countries had long colluded with each other to help each other in the development of nuclear weapons, and the German submarine U-234 had been transported in a vain attempt to transport 550 kilograms of uranium oxide to Japan.

Fortunately, it was intercepted.

And the submarine I-704 drove back with a load of nuclear materials!

Luckily, it sank.

However, the nuclear materials it transported are still of great significance to Japan today!

Japan has never given up its efforts to become a great power with status. And in today's world, to be a great power with status, you must have nuclear weapons.

Japan has been working on this point for a long time.

However, nuclear weapons are not so easy to do.

As we all know, the principle of the atomic bomb can be easily found on the Internet, and many of the corresponding processes can be carried out in industrial countries such as Japan, even in semi-industrial countries. However, there is one thing that has stumped many countries that aspire to enter the nuclear club.

That's nuclear material.

One can't help but ask, aren't nuclear power plants everywhere, and are nuclear materials so difficult?

Yes Nuclear materials used in nuclear power plants are relatively easy to obtain. However, it cannot be used for nuclear weapons, because it is not enough! In fact, Iran is currently stuck here.

The same is true for Japan. It is currently under the close surveillance of the International Atomic Energy Agency (IAEA) and has no chance of accumulating weapons-grade nuclear material. Among the 32 countries that possess more than 1 kilogram of nuclear material that can be used to make nuclear weapons, Japan ranks 23rd and last among 7 developed countries (G7).

However, weapons-grade nuclear materials lie quietly in the wreckage of the I-704 submarine as long as they can be obtained. With Japan's industrial capacity, it will succeed in building nuclear weapons within three months, and it will immediately become a de facto nuclear power.

Therefore, Japan salivates over I-704.

However, in accordance with international maritime salvage regulations. Shipwrecks do not have the right to salvage because of the old owner. Rather, in whose sea area, who has the right to salvage.

Japan has never used the brains of secretly salvage. But that road is currently blocked, watched, and can't be done in secret.

Therefore, in order to salvage the I-704 submarine, it is necessary to gain control of the Diaoyu Islands and the surrounding waters.

Therefore, it is necessary to be vigilant against Japan's ambitions for the Diaoyu Islands.

This is because a nuclear-armed Japan would be a nightmare for world peace.
