"Heaven descends on the people, they must first work their minds and empty their bodies......" Li Guang has almost relied on this sentence to support himself these days. I didn't dare to spend money except for eating, and I almost relied on two legs to walk all over New York. However, there was finally some gain, and some of the raw materials and equipment for making torpedoes were basically recognized. In particular, the raw materials and equipment for the manufacture of lead-acid batteries are basically complete.

Li Guang is anxious these days, knowing that the Italian Alfred's freighter will return on February 20. It wasn't until 15 February, when Li Guang was penniless, that he got the good news. His first patent fee was in his hands.

It's a whole 30,000 dollars, and that's just the design patent for the Coca-Cola bottle. Li Guangke knew the scale of Coca-Cola in later generations, and this amount of money was nothing to a giant like Coca-Cola, and this price was definitely not sold to a reasonable value. But Li Guang, who was already penniless, accepted it without resistance.

However, Li Guang was extremely satisfied with a clause attached to the patent contract, which stipulated that Coca-Cola would pay Li Guang 0.1 cents for every bottle of plastic bottled beverage sold. Li Guang was almost stunned by this one, he was so happy. 0.1 cents doesn't sound like much, but it can't withstand Coca-Cola's large sales, and the speed of development is even more terrifying. It is almost immeasurable how much benefit this humble contract will bring to Li Guang.

In the days that followed, good news continued one after another. The ballpoint pen was sold for 40,000 US dollars, and the additional clause was that Li Guang was given a commission of 0.1 US dollars per pen for ten years. The price was not beyond Li Guang's expectations, but the high commission of $0.1 per pen was too much, and you must know that in later generations, an ordinary ballpoint pen would only cost one yuan.

The design of the hiking boots was also sold for 2,000 dollars by Lapan Gamaliel. Other benefits vary, but one of the most striking is the cigarette filter. It was sold for a staggering $170,000 by the Jewish merchant Rapangamaliel.

By 20 February, Li Guang had nearly $400,000 on hand. This was a myth of wealth to the Jewish merchant Rapanga Mariel. And that's not all, there are still a few patents that have not yet found a suitable buyer, and it is estimated that there are tens of thousands of dollars in earnings. According to Rabangamariel's calculations, Li Guang can also get more than 100,000 US dollars from the patent commission every year.

In this day and age, $400,000 is not a small number. Even in the extremely wealthy United States, this is a very large number. If you compare the purchasing power of the dollar in the thirties and the dollar in the twenty-first century, you can see the horror of this figure.

In this era, the price of an ounce of gold was about $35, and in the 21st century, the price of an ounce of gold reached $1,700 at its high. In other words, the value is about 50 times different, and 400,000 dollars in this era is equivalent to 20 million dollars in the 21st century.

If the reader doesn't already have an idea, here's a simple example. China's most elite German armor division before the Anti-Japanese War, a division's equipment was only 1 million US dollars, including 12 75mm Krupp field guns in addition to light weapons.

In the United States, the sales price of a Ford car is only about $300. The annual income of the American middle class was only one or two thousand dollars at this time.

Now that he had enough financial resources, Li Guang immediately asked Captain Alfred to stop a few more days, and he wanted to bring back to Uruguay some of the equipment for making batteries.

With money, Li Guangcai really has the appearance of a little boss. Xu Zhan had already become Li Guang's follower at this time, and among the newly recruited Chinese employees, there were also several mechanical and electrical technicians, and it only took ten days to work together. Li Guang spent 100,000 US dollars to buy thousands of tons of equipment and raw materials.

In mid-March, Li Guang returned to Uruguay with his staff. The trip did not recruit enough people, only 10 people, except for Xu Zhan, who had six skilled workers and three seafarers, and the other 20 or so were family members of employees. Some of these people will also be able to work in factories in the future.

On March 15, the freighter docked at the dock in Rameh (the maintenance berth can be used as a wharf), and Ramo was already anxious at this time, waiting for Li Guang like the stars and the moon. He is now forced into debt by the bank, the deadline is approaching, and his sponsorship of Li Guang to go to the United States is purely a gamble in desperation.

And now Ramo is waiting for Li Guang, who has returned victoriously, and Ramo, who was shocked by Li Guang's achievements, was almost stunned. In just over a month, Li Guang earned half of all his wealth.

What happened next was logical, and Rameau hired a bank, a lawyer, and an accountant to draw up a contract to transfer all his factories and a private island in Uruguay to Li Guang for $200,000. A little surprise was that Rameau agreed to Li Guang to use all his torpedo technology free of charge, but as an additional condition, the torpedoes produced by Li Guang in the future would be sold to Rameau. And Li Guang readily agreed to this request, and it is impossible to thank this Spaniard who extended a helping hand in his most embarrassing situation.

This also made Li Guang feel a little comforted, and Li Guang was a little sorry for the research results of the torpedo that occupied Ramo, although he was very disdainful of Ramo's torpedo. But all the experiments and technical accumulation that Ramo did were not possessed by Li Guang.

A few days later, Rameau took his torpedo to Spain to start his arms business. Before leaving, Ramo handed Li Guang a box of drawing materials. Among them was a complete set of drawings for the American S-class submarine, which Rameau took advantage of the economic crisis to obtain from an American designer for $3,000.

Li Guang couldn't help but smile secretly, this Ramo, who wanted to regain his family's glory in arms, although his business was not developed, there were really a lot of small actions in private. Presumably, it is not developed because it is not at the right time, and it is estimated that Ramoken generously handed over the torpedo technology to himself, and I am afraid that many of these technologies were obtained by various means.

This S-class submarine, displacement (tons): 903 when floating, 1230 when submersible, diesel engine and electric propulsion, using two diesel engines and two electric motor drive, the speed on the sea can reach 14.5 knots, and the sneaking speed can reach 11 knots. If you sail at economic speed, you can run 8,000 nautical miles.

Compared with the submarines of Germany and Yuben, it is not advanced, after all, it is a product of the late stage of World War I.

And in Li Guang's eyes, this submarine is simply ugly. Like a slender steamer with a lid, the streamlined and teardrop-shaped shape pursued by modern submarines is simply not seen on it. (Note: Most of the submarines of World War I and World War II were not completely detached from the shape design of warships.) And what Li Guang criticized the most was that the speed was too slow, and if this thing was discovered by the destroyer, it would not be able to run away at all.

No wonder Li Guang, a naval idiot, has only seen some parameters of nuclear submarines on the Internet, nuclear submarines are powerful and naturally very fast. How did he know that although the American submarine had many problems, it was actually no worse than the German U-boat in terms of speed.

The only tactic of the submarine was a sneak attack, which Li Guang slowly realized in his later days.
