It was a landmark event that the most stubborn Kevin was able to devote himself to the 'pirate' cause of the fleet, which proved that the last thorn in the fleet had also surrendered, and the upper and lower levels, whether Chinese or Prussians, were completely integrated.

The cohesion of military morale in the war has always been an extremely difficult and big thing, not to mention the army that the soldiers of the two countries of the Zhiyuan Fleet have temporarily put together, and the language, culture, and national attributes are different, and the depth of understanding of this mission is also different.

The Prussians regarded this mission as merely a mission, while the Chinese regarded this return journey as a training exercise, a test of blood and fire.

In fact, there have always been differences, but the Prussian people's natural obedience to military orders has made people ignore this, and Kevin is not a soldier, so he is more likely to have a disagreement with Xiang Ying and them, after the war from the Marshall Islands, he squeaked all the way, in fact, he represents a common idea in the subconscious of most Prussian soldiers.

When the wind is good, there will be no problems when the contradictions are hidden underwater, but if the war does not go well, these hidden differences are likely to be fatal crises.

Xiang Ying's series of psychological warfare against Kevin was not just against him alone, in fact, those words were also said to these Prussian naval soldiers, if they can't get everyone to really work together as soon as possible, I'm afraid the next tens of thousands of miles of travel will be really difficult to walk.

Xiang Ying and the others did not disappoint Xiao Letian, they relied on their own wisdom and good arguments to solve this problem. It was a miracle that even those Prussian sailors were stupid enough to make the old-fashioned Kevin shout and shout for battle.

The altar was presented to a light British merchant ship, the white flag was hoisted by the rudder of the Zhiyuan, and the surrendered British sailors hoped to save their lives with three boxes of gold coins on board, but unfortunately they did not meet pirates in the normal sense, and they had already fallen into the national war.

After the gunshots rang out, the sea was bloody, sharks in the deep Atlantic Ocean swam from all directions smelling blood, and merchant ships slowly sank on the surface of the sea and rolled up a large whirlpool.

Kevin, a devout Protestant, knelt on the bow of the ship, clasped his hands in a silver cross, and muttered, "May God guide your souls to ascend to heaven...... I'm sorry, but I don't regret it, because in the process of rejuvenation of any nation, there will always be people who die, and there will always be people who go to hell......"

"Someone has to be sacrificed on the altar, and unfortunately I don't want us Prussians to be sacrificed in blood, and these Chinese don't want their own people to be sacrificed...... Since you have thrown yourself into the torrent of national war, then life and death should be lighter, may God bless you!"

Kevin was surrounded by Sun Chujian, who had just come from the clipper to participate in the evening memories, and he did not expect that the German engineer would have some religious compassion and poet temperament, and finally mixed with the pragmatism philosophy unique to scientific researchers.

"O complicated Prussians......! If you Prussia don't unify Germany and defeat Britain and France, then God will really not open your eyes!"

Kevin didn't care at all about Sun Chujian's teasing, "Thank you for your compliment, but we don't believe in God, we believe in God...... We believe that God is fair, why is the wealth of this world owned by Britain and France? Prussia also needs to survive, we also need to rise, we also want a happier life, I believe that God can hear the common cry of our nation, because we are praying for our nation day and night!"

"Well, God will bless the Prussian ......," Sun Chujian did not dare to talk too much about religious issues with a devout believer, so he quickly changed the subject.

"Dear Mr. Kevin, in these battles, the Zhiyuan 210 caliber main gun has shown its great power, but I have a question, why don't we produce a larger caliber gun, such as 310 caliber or 410 caliber ......"

"Oh my God!" Kevin hurriedly drew a cross on his chest, "Another believer in the supremacy of firepower?Young man, don't always fantasize like this, it's okay, now this 210 caliber cannon can be regarded as the pinnacle of metallurgical technology at this stage, where is it so simple to increase?"

"First of all, you have to solve the problem of material, the hardness of the steel used in the artillery is not enough, especially the hardness of the internal rifling, do you know how serious the wear and tear of the rifling is by the high-speed rotating shell?

"The more powerful the main cannon, the greater the charge, the more kinetic energy, and the greater the pressure on the barrel, can you just increase it?"

"Secondly, there is the structure of the battleship, which is ultimately a mobile firing platform for the artillery, and it has to withstand the full recoil of the gun's fire...... You should have seen a salvo of naval guns from a sail battleship, and they never fired at the same time, they were all fired sequentially, and even half a second apart could defuse the powerful recoil!"

"Zhiyuan is even more so, the 210 main gun is already the limit of the structure of this battleship, no matter how large the caliber is, the structural strength of the entire battleship must be improved, the 310 caliber gun you said, without a displacement of more than 10,000 tons, don't even think about installing ......"

"As for the 410 caliber...... I don't think I'll ever think about it unless I can build a giant steel ship of 50,000 or 60,000 tons! With all due respect, I'm afraid I won't be able to see this kind of sci-fi warship in my lifetime......."

Kevin patted Sun Chujian's arm, "The most critical point is that your Prime Minister strongly requires the caliber of the artillery to be about 200 mm, too big he doesn't want it, too small and don't want it, and then through multi-professional joint discussions, the standard ...... of 210 caliber was finalized."

"Since the Prime Minister of the East is the one who pays for it, of course we have to work according to the customer's requirements, and God knows why he has such a request...... Well, the meeting is about to start, and the dinner afterwards is sumptuous, and our housekeeper is really good, with excellent beer and wine!"

Night falls in the Atlantic, and the innocent souls of the dead may be watching them with hatred in the sky, even cursing them with the most vicious curses, but this group of soldiers doesn't care, this is a group of fighters who do not hesitate to go to hell for the sake of national rejuvenation, as long as they can strengthen the mother country behind them, what does it matter if they go to hell.

Some questions are destined to have no answers, and Xiao Letian can't tell everyone that the development limit of naval artillery is 400 mm caliber, and it will not appear until the end of World War II.

Moreover, the performance of naval guns does not only depend on the thickness of the barrel, but also an important indicator is the length of the barrel, which is commonly known as how many times the caliber, which is also an important indicator of the performance of the gun.

Is Xiao Lotian rich? For ordinary people, he is very rich, and the huge forces that Xiao Letian has single-handedly formed are also very rich, but if this money is compared with the naval arms race in the future, it is really not enough.

In the 19th century until the 20th century, the navy burned as much money as the Star Wars program in later generations, and all countries did their best to upgrade the navy from generation to generation.

In the end, the "Washington Naval Treaty" was even needed to limit the number and attributes of warships of various countries, which shows that the arms race is a bottomless pit no matter what era.
