Standing in the round hatch, Captain Hanafang glanced at the bow torpedo compartment that was already empty, and found nothing unusual, perhaps because he was nervous, the Navy Shaozo shook his head mockingly, and then turned around to catch up with the group that had gone away.

From the point of view of the two Germans, the rest is all garbage time, they have seen the latest high-horsepower MAN diesel engine, they are completely uninterested in the Japanese submarine's outdated diesel engine, if it is equipped with the latest Nissan power submarine patrol A, maybe it can still arouse the captain's interest, but the Yi 60 was completed eleven years ago (1929), and the machinery and design are obviously behind this era.

The decade before World War II was the era of the world's fastest update of military technology. The best example is France, which was the name of Europe's number one army before the war, except for a few elite units, most of the soldiers were holding outdated weapons, using outdated combat techniques, and under the command of a group of outdated officers, fighting a war in the new technological era, and finally getting such a result, in fact, it is not surprising at all.

In fact, Japan's basic technological development has been stagnant for many years, but the military top brass does not seem to care about this aspect at all, and most of Japanese society at this time has been blinded by the victories of previous wars of aggression.

At the beginning of the Taisho and Showa periods, the Japanese tightened their belts and, with the help of the British and American powers, established a complete industrial production system and trained a modern army that was unique in Asia. By the Showa era, Japan had been able to produce all the world's modern weapons on its own, regardless of their performance, which was a remarkable achievement, given that there were still many countries in Europe and the United States at that time, and even the rifles in the hands of soldiers had to be purchased from foreign countries.

The achievements of the modern development of the Japanese Empire are indeed remarkable, but after raising their eyebrows, the Japanese gradually became complacent, which is the defect in the character of the Japanese island nation, which happened to be the early Showa era out of political needs, against the left-wing revolutionary ideas, and set off a nationalist upsurge in Japan, and Japan's achievements were deliberately exaggerated, so as to prove that the Yamato nation under the leadership of the emperor was excellent and by no means lagged behind those Western whites. After more than 10 years of propaganda that has been carried out day by day, it has now penetrated into the hearts of the Japanese people and the military, and in the end even the Japanese top brass themselves have come to believe it, and they arrogantly believe that Japan's military technology is already in the forefront of the world and can completely compete with the European and American powers.

In fact, at this time, Japan's domestic technology was only eating the old books of the Taisho period, because most of the experts and professors who stood in the leadership positions of scientific research or design departments were educated in Europe and the United States during the Taisho and even Meiji eras. The generation that was really cultivated by Japan's local colleges and universities was in the age of the enthusiastic young man, and his mind was full of the emperor's eight Hong Ichiyu, but they lost the objective thinking and innovative ideas of the older generation of Japanese scholars.

In recent years, in order to seize orders from the Japanese army and navy, Japan's military industrial enterprises have pursued novelty, and like to pile up a bunch of complex and immature technologies into the design of weapons. However, the Japanese military is very much in this way, and the military top brass blindly pursues all kinds of new technologies, completely ignoring the needs of the actual army, and seems to use fashionable technology, which represents advanced performance and can defeat the imaginary powerful enemy army in their hearts.

The powertrain of the I-60 is completely copied from the German diesel engine design, with only Japan's own improvements added to some auxiliary equipment. Robin and Igor had little problem with the Japanese approach, which was common in the early twentieth century, and when Japan bought the engines, it had already paid for technology transfer.

In the early days, the German production industry relied on copycats of British and French industrial products to seize the market share in Europe, and German industrial products during that period were famous throughout Europe for their cheap and inferior products. The Germans were not born so rigorous, they were once as carefree as the people of the rest of Europe, and the modern Germanic people's national character of order and obedience was slowly "cultivated" by the whips of successive sheriffs and the steel scabbards of officers.

Japan's current marine fuel engine technology has reached the pinnacle of what they can do, and I believe that without outside help, there will be no breakthrough in the next few years. And for now, Japan will not have the opportunity to acquire more advanced technology, because the German Führer blocked this possibility from the source.

A full-blown technical blockade of Japan, that's what European countries are doing at the moment, and the governments and the media are quite tacit, so this blockade doesn't exist for the outside world at all, because you can't produce any evidence of it.

The German head of state proposed to establish a unified standard for the control of military technology throughout Europe, which was supported by Britain, France, the Netherlands, Italy, and other countries, and they also saw the threat that the proliferation of advanced military technology might pose to their own security.

Historically, there have been two main sources of new technology in Japan, one is the United States on the other side of the ocean, and the other is the German-Italian alliance in Europe. Now that the German-Italian alliance has changed, Italy has become a hardcore vassal of Germany, and the results of research in Italy have been more strictly regulated, all the recent requests for "exchange" by the Japanese have been met with euphemistic prevarication. Not to mention the German side, the new Führer obviously had a special habit of protecting food, if only in the economic field, but the trouble was that he extended this habit to the field of science and technology, and he was more enthusiastic and familiar with these technical problems than the former Führer. Hiroshi Oshima's report mentions that the Führer himself was a genius inventor who had personally designed and improved many of Germany's active equipment and weapons.

After losing the technical support of Germany and Italy, it is still unclear whether Japan's military industry will rest on its laurels or become indignant, but what is certain is that the development of Japan's new weapons will certainly be affected in this regard.

The floor of the aft torpedo compartment was much higher than the power compartment, and it was necessary to climb a few steps before entering the door, and Robin and his family did not enter this small cabin, but just looked inside on the platform at the hatch, and hastily ended the tour of this cabin.

The German and Japanese officers laughed and laughed as they returned to the command cabin, where a group of Japanese sailors, under the command of two special agents, carried supplies exchanged for the Germans to the aft deck through the entrance and exit of the deck at the top of the power cell. So when Robin and his crew returned to the outside of the boat along the control tower shaft, the cardboard boxes loaded with vegetables and canned food and the wooden barrels loaded with condiments were neatly placed on the rear deck of the Yi 60.

Immediately the two sides shook hands and hugged goodbye, and Robin did not take the rowing boat from the Japanese side, but got into the power rubber boat sent by the U106. During this period, the small gasoline engine at the tail of this German rubber boat attracted the attention and curiosity of many Japanese naval officers and men.

"Okay, I've seen it all, what exactly did you just take?" The dinghy crossed the median line between the two submarines, and Igor turned to the plank seat in the boat and asked aloud as he faced Robin.

In the bow torpedo compartment of the Japanese submarine just now, Igor clearly saw that Robin had taken something from the supply pile next to the torpedo tube and stuffed it into his trouser pocket, and at the same time slapped the torpedo tube with his other hand to divert the attention of the Japanese. Robin's tricks were all too familiar to the lieutenant captain, and they had "learned" them from an Italian gendarme when they traveled to Italy together.

In fact, in the second half of the visit, the co-captain spent the time in fear, and he was really worried that the behavior of the boss would be discovered by the Japanese side. It wasn't until he boarded his own ship that Igor finally breathed a sigh of relief, he had some complaints about Robin in his heart, and at the same time wondered why the other party was taking such a risk.

"You don't say I'm looking for you too, I took a small notebook, it seems to have some data written on it, and when I get back to U106, you can help translate it, maybe there will be some interesting discoveries." Robin smiled and patted his pants pocket.

The handover of supplies went very smoothly, and the Germans exchanged a large amount of canned beef and sardines for a batch of fresh vegetables from Japan and special products such as Yamato boiled canned food, and both Germany and Japan were very satisfied with their "harvest" this time. The Japanese thought they had received the "secret training methods" of the German Navy, while the Germans got up close and personal with the training and equipment of the Japanese Navy. And until both sides waved goodbye and turned their rudders to leave, the Japanese were unaware of the "crime" committed by Captain Robin from beginning to end.

The U106 and the I-60 then dived one after another, and the first head-on contact between the German and Japanese navies in Southeast Asian waters came to an end.
