On 1 September, the Ariane docked at the port of A Coruña in northern Spain, and Ramo greeted Li Guang and his party at the port early.

At this time, Rameau had already regarded Li Guang as a god of wealth, Li Guang not only extricated Rameau's economy from the predicament, but also took refuge in Franco, the leader of the Spanish rebels, under the guidance of Li Guang, and not only sold out the torpedoes quickly, but now has obtained a good position in Franco's group - the Minister of Arms Procurement under the Admiralty of the National Army (Rebels). Although most of the weapons on both sides of the Spanish Civil War were provided by the forces represented by Germany, Italy and the Soviet Union, there was always some that needed to be purchased, and the role of Rameau was quite good. And it was Rameau who defected to the rebels when they were still very weak, and the timing was just right, and the result was naturally reused, not to mention that the hundreds of torpedoes provided by Rameau were indeed of good quality. And Rameau attributed all this luck to Li Guang.

This time Li Guang saw Rameau, Ramo was completely different from when they first met, his face was full of red light, he was not wearing a military uniform, he was wearing a decent suit, and he looked like a successful person.

Li Guang had great respect for Ramo, a man who helped him in his most difficult times. Rameau's current state has clearly entered the role of an arms dealer, and as soon as they meet, they can't wait to start discussing torpedoes.

In August, the Spanish rebels defeated the Axe Army on the battlefield, and now the whole of northern Spain is at its most intense, and according to Rameau, the rebels will soon occupy the whole of northern Spain.

The north of Spain is the industrial core of Spain, and as long as it is occupied, the political axe army will definitely lose.

Rameau has already begun to get started, preparing to acquire several factories for the production of torpedoes. And Li Guang's arrival at this moment gave Rameau greater expectations, and in just a few months, Li Guang doubled the range of torpedoes that Rameau had studied for one or two decades. This is a remarkable achievement, and Ramo is well versed in torpedo technology, and he understands the value of it.

After the experiment, Rameau found that Li Guang was not lying at all. Li Guang said that if he was given a longer time and more research funds, then he would be sure to increase the range of the torpedo to 4.5 kilometers.

In the time that Ramo was in contact with Li Guang, he already knew that this oriental guy had a high vision in terms of technology, and when he saw the results of this experiment, he was convinced.

Soon the two reached an agreement, Rameau also handed over the power torpedo technology he had researched (using an internal combustion engine) to Li Guang, and Li Guang would supply electric torpedoes to Rameau in the near future, and Li Guang would be the battery supplier for Rameau when the factory was fully built. And Li Guang in the whole of Europe could only supply him with torpedo batteries.

This condition is not fair to Li Guang, which limits the sales of Li Guang's batteries, and the profit must be stripped by Ramo. But Li Guang saw that he was very happy in the face of the life-saving benefactor, and agreed.

In the ensuing conversation, Rameau learned that Li Guang was planning to develop submarines, and immediately suggested learning from the German U-boat or the Dutch C-class submarine, which was more excellent. But when Li Guang asked how he could get the drawings, Ramo couldn't help.

Submarines of this era had a characteristic feature of installing a deck gun. Li Guang was originally not interested in this thing, modern submarines are not equipped with deck guns at all, and he has never seen this thing on the Internet pictures. Installing a deck gun not only affects the speed of the submarine, but also increases the noise of driving. However, Zheng Xuechang's explanation is that submarines are equipped with too few torpedoes, and when encountering water targets of little value, the combat method is often deck guns.

This theory is an eye-opener for Li Guang, and this is partly in line with Li Guang's plan. If Li Guang wanted to rob the freighter, he couldn't just torpedo it and sink it, and having a deck gun would undoubtedly be of great help.

For deck guns, submarines of this era were often a 76mm caliber field gun or cannon. Li Guang had high requirements for deck guns, and he aimed at the famous German 88 anti-aircraft gun FLAK36.

The German 88mm anti-aircraft gun was not famous at this time, but it was famous when the German army found that its armored power against its opponents was almost invincible in World War II. The famous Tiger tank is the installed 88mm anti-aircraft gun. Although Li Guang is very weak in military history, he has seen many articles on the Internet explaining this 88mm gun, which has been blown by German fans on the Internet.

And the reason why Li Guang chose this gun was because he took a fancy to the armor-piercing ability of this gun. He was deeply shocked to see the Izumo cruiser in Shanghai, with its powerful firepower and heavy armor. Now he does not expect the deck guns of the submarine to be able to deal with the cruisers of the Japanese army, but it should be able to deal with the destroyers of the Japanese army.

The deck gun used on the German U-boat was only 35 times the diameter, while this anti-aircraft gun had a 56 times diameter barrel, which had a completely different penetrating power.

The shells used in the FLAK36 were mainly grenades and armor-piercing shells. The grenade weighs 14.7 kg and has a total length of 931 mm, and the warhead weighs 9.24 kg and has a warhead length of 385 mm. At a firing range of 1000 meters, armor-piercing shells can penetrate steel armor 106 mm thick.

In the Spanish Civil War, there was a famous saying: "There should be tanks everywhere you go." As a result, the Soviet Red Army also "created" another "famous saying": "All artillery should be able to hit tanks." The Germans have made the best interpretation of this "famous saying" with practical actions, as evidenced by the 88-mm anti-aircraft gun equipped with armor-piercing shells.

The destroyers of the Japanese army generally had only a dozen millimeters of armor, while the light cruisers had only more than fifty millimeters of armor. Li Guangxuan chose this gun, not asking the submarine to be able to confront the battleship, but only to ensure that he had the strength to fight back as a last resort. If you want to fight with large-caliber naval guns, there is no door.

When Li Guang made this request to Rameau, Ramo behaved very positively. Rameau also knows that although his torpedo technology is good, it is not brilliant in the world, and compared with Li Guang's battery technology, the value is not at the same level at all, and the value of invention and innovation is naturally greater. And the cooperation conditions agreed by Li Guang are undoubtedly very beneficial to Ramo. Therefore, Ramo is very dedicated to Li Guang's request. What's more, Li Guang's use for this gun is only to be installed on a submarine as a deck gun, and there is no need for a walking mechanism. The damage to a cannon on the battlefield is often not the barrel being blown up, but mostly the mechanism being damaged. In short, such a request gives Rameau a lot of room to manoeuvre.

The Ariane stayed in the Spanish port for four days, and Rameau was done, and the five 88mm anti-aircraft guns were sold to Li Guang by Rameau as scrap. Originally, the price of an 88mm gun was about 60,000 US dollars, but the cost of five scrap guns was only 50,000 US dollars.

However, the artillery shells Ramo could not be cheap, and Li Guang knew that Ramo had done his best to buy nearly 2,000 armor-piercing grenades and anti-aircraft artillery shells, worth 50,000 US dollars. Artillery shells are really expensive enough, an anti-aircraft artillery shell is worth more than 30 US dollars, a grenade is also worth nearly 20 US dollars, and an armor-piercing shell is as high as more than 40 US dollars.

Through this arms purchase, Li Guang truly realized why China's military strength is inferior to that of the original. The country is too poor to be armed with artillery and shells at all. As a Chinese leader at this stage, if he has a million dollars, he will undoubtedly choose to equip a division of light equipment, rather than buy less than 20 advanced 88mm anti-aircraft guns. However, it may be possible to resist the attack of the Chinese army with light equipment alone, and it is even more difficult to defeat the opponent, and this is the dilemma of the Chinese army.

Thinking of this, Li Guang even doubted whether his choice was correct, and whether it was an extremely inappropriate path to start with the navy? Or is it a hopeless path?

With this doubt in mind, Li Guang said goodbye to Ramo and arrived in Hamburg, Germany, two days later, where he sold tungsten ore.

The Navy provided contacts for the German side, and tungsten ore, a scarce material, was not sold here at all. As early as Li Guang set out from Uruguay, he planned a trip to Germany, where he needed to inspect and buy diesel engines.

In this era, German marine diesel engines are second to none in the world, their quality is no worse than that of the United States, and the price is lower than that of their American counterparts.

Li Guang's time to this era is still too short, and this inspection of diesel engines once again gave Li Guang a great inspiration. It was only at this time that Li Guang discovered that the diesel engine of this era was so huge. A 1,000-horsepower marine diesel engine turned out to be six meters long, nearly two meters high, and weighed fifteen tons. And the noise is even louder.

After careful observation, Li Guang found his own usefulness. At this time, the diesel engine is not to mention turbocharged, and the German diesel engine uses the simplest in-line fuel supply system, and there is no even the most basic PT fuel supply system.

Li Guang is only rough about the battery industry, but he works in the agricultural machinery factory at home, and he has no less contact with diesel engines. Although he could not design a diesel engine, he was familiar with the various parts of the diesel engine. The so-called PT system is simply a high-pressure oil supply system. This was invented in the fifties by the American company Cummins. In fact, the structural principle and even the manufacturing of this system are very simple, and it can be completed in this era. The advantage of this system is that the power is significantly increased in the same size combustion chamber. The pressure of the in-line oil supply system can only reach more than ten MPa, while the PT oil supply system can easily reach seventy or eighty MPa. Moreover, the full combustion of fuel is incomparable to the in-line fuel supply system.

Li Guang was almost overjoyed by the discovery, a technological advance that could not be matched by the Coke bottle and ballpoint pen, which could almost revolutionize an era.

Marine diesel engines are huge, and automotive diesel engines are now huge. Although the volume of the vehicle diesel engine with the same nominal power is only a fraction of that of the ship, it is already very huge compared to later generations. (Note: The design of the engine for the vehicle is different from the design for the marine engine and the design for the generator, and the engine for the vehicle has a duty cycle, which means that it cannot run at maximum power for a long time.) ）

Li Guang immediately started to think that this kind of technology must not be sold easily, and it is no exaggeration to say that this kind of technology can even determine the rise and fall of a country, and even affect the course of history.

For example, if Germany's strong mechanical production capacity had been obtained, Germany's already powerful armored corps in World War II would have been very powerful to a terrifying level. Later generations commented on the reasons for Germany's defeat and always mentioned one reason - the Soviets defeated Germany over quality by quantity. And this victory is only to the point that the technical level is not too far behind, and if the technical level is an order of magnitude worse, then it will be possible for quality to outweigh quantity.

For example, if Germany had a small 1,000-horsepower tank engine, then the German Haw Par tank would not be constrained by power, and would not only have strong firepower, but also thicker armor, and the T34 and even KV heavy tanks that the Soviet Union was proud of would become a live target.

As a traverser, Li Guang has actually never discovered his true strengths. He knows a lot of things, but what is too advanced is fundamentally transformed into productive forces under the existing conditions. And Li Guang once racked his brains to think about the most suitable product for his development, and the conclusion he came to at that time turned out to be a tank. The reason is that when he was in the agricultural machinery factory, he was very familiar with the track drive mechanism and suspension mechanism, and if he was asked to design a tank chassis, he should still be quite sure.

However, it should be said that the chassis scheme will definitely work well for light tanks, but it may not work well once it is used for medium and heavy tanks. Moreover, the crawler single-flow drive system that Li Guang is familiar with, although it is a perfect system that has undergone many innovations and progress in later generations, but after all, it is a civilian use, and there is still a question mark whether there is a problem in military use.

Even if this system is completely fine, the value is still not on the same level as the epoch-making innovation of the diesel engine.

For submarines, the drawings in Li Guang's hands were designed by the Americans with two 1,000-horsepower diesel engines and motor dual-engine coaxial dual drives. Li Guang was extremely dissatisfied with its speed, and he hoped to buy a diesel engine with about 2,000 horsepower. The power of the motor is in Li Guang's battery, a high-tech product in hand, and it must be improved (the motor technology is not much different from Germany and the United States.) ）。 This allows the maximum speed of the submarine to be increased somewhat.

On the third day of his stay in Hamburg, Li Guang waited for a German introduced by Rameau, Claude.

Diesel engines Li Guang may not necessarily be purchased in Germany, but there are two things on submarines that are best purchased in Germany. And this Claude is here for this.

The first is the periscope produced by ZEISS, and then there are the listening and sonar equipment made in Germany. Claude is the head of the procurement department of the German Navy, and he is a peer of Rameau.

Although this kind of thing may not be considered the most advanced in the world, military products are not something that Li Guang, a businessman, can reach out for.

Claude was in his forties, but he was a gentleman, and he expressed sympathy for the state of China as soon as they met. This Claude actually spoke in Chinese, and this person has been in China for many years and is quite familiar with China.

Claude knew Li Guang's intentions, and he said that he could sell the materials that Li Guang asked to buy, but the price made Li Guang almost grinning.

A set of periscopes, from the mechanical part to the optical part, is only a few hundred kilograms, and the price is 15,000 dollars. The sonar system costs $20,000. Li Guang, who had just learned a little about the huge profits of arms products, once again experienced the huge profits of high-tech products. It's like cutting meat with a knife.

Later, after Li Guang got the product, he figured out what the so-called sonar was. It is even more slanderous to the Germans for a long time, not to mention the periscope, the so-called sonar in this era is nothing more than a few ultrasonic generators and an oscilloscope, as well as several quantities of energy conversion originals. If this thing is put in modern times, the surname can exceed a hundred times that of it is only a few thousand yuan. Don't you see that even the reversing radar of the car is ultrasonic? The quality of ultrasonic rangefinders everywhere on the Internet is many times better than this pile of garbage.

But there is no way, Li Guang knows that it is profitable, but he can't do it. So I gritted my teeth and bought three sets.

When he finally left Germany, Li Guang not only spent the money he was entitled to, but also used part of the funds of the Chinese Navy. In the end, Li Guang returned to Uruguay with two diesel engines of 2,500 horsepower and two electric motors of 1,000 kilowatts, as well as three periscopes and three sonar equipment.

Li Guang, who was seriously short of money, made a trip to a certain red-imperial embassy before leaving Germany, preparing to make some business with polar bears at the right time.

On the way back, Li Guang felt that his plans had to change. According to Li Guang's plan, the cost of the submarine was about $1 million, and now Li Guang could not get that much money anyway. (Note, the best submarine of World War II in the United States, the Shark-class fleet submarine, has a displacement of 2,000 tons and costs no more than $3.3 million.) In the latter part of World War II and 37 years, the price climbed more than doubled, excluding profits, the author's speculation is roughly reasonable. When Li Guang earns a million dollars, I don't know when it will be. Do you just keep waiting? And his own attack will not stop because Li Guang is short of money.

Li Guang calculated the funds on hand, and there were less than 200,000 US dollars. In Uruguay, Li Guang now owes the bank $100,000.

Not only that, Li Guang also owed Ramo about $100,000 for cannons and shells, which needed to be repaid with torpedoes. Nearly $200,000 is owed to the Chinese Navy, which also needs to be repaid with torpedoes.

And the 300,000 torpedoes had to be invested in at least 150,000 dollars in materials and labor. To sum up, Li Guang actually has a gap of 50,000 US dollars.

Don't forget, now Li Guangke has seventy people on hand, and these will also cost money. In other words, Li Guang will have to get at least $100,000 in a few months to break even.

Li Guang rarely cared about money in later generations, but now he can be regarded as a rich man, but he is still only a baba. Under economic pressure, Li Guang was not even interested in teasing the two beauties.

After Su Zizi taught Li Guang a "Night at the Military Port", she began to have a little meaning to Li Guang. It's a pity that after her brother Su Qing's body recovered a little, Li Guang was no longer approachable. Another big beauty, Yuan Ran, is a little too rational, as if the ladies majoring in law have a little bit of this problem. In comparison, Li Guang still likes his sister with a little surname.

Leadership is not so easy to be. Li Guang finally came to a conclusion.
