Of course, what surprised Mr. Major even more was the 170-mm heavy gun.

I'm afraid that even he didn't expect it, he was still wondering before, saying that it was a 210 mm heavy gun, as if the caliber of the barrel was a little wrong, if it was other types of artillery fire, in the German army, it seemed that there was no heavy gun of a similar caliber.

Liu Yun put his hand on his chest, bowed to everyone very elegantly, and talked a little indifferently, "Actually, it's not a secret, Your Excellency Haosen, think for yourself who else is the first to know about this type of artillery besides your country, don't be in a hurry to answer, think about the 240 mm mortar."

"240mm mortar?" Mr. Major could not help but be shocked.

He seemed to have thought of something, and asked with some horror, "Your Excellency Hausen, that is the treasure of Germany, no one would want to give this cannon to others, right?" If we are in the hands of Britain and France, we will be in danger."

Is the mortar very hanging? It's just general, to put it bluntly, it's a bit like the early front-loading cannon used during the Opium War, where a lead bullet was placed in a semi-enclosed iron pipe, and some gunpowder was placed under the lead bullet, and the lead bullet was fired at the enemy as soon as it was ignited.

After the Franco-German War in 1870, the front-loading cannon was gradually phased out.

So, is this thing really outdated?

Of course not, during the First World War, the Germans used the principle of mortars to redevelop mortars, which were specially used to conquer enemy fortifications, or fortresses, etc., and made countless military exploits, which made Britain and France and other countries fearful, and their reputation spread abroad.

Moreover, Germany is about to launch a second European war, and once this cannon is obtained by Britain and France, it will indeed be a disaster.

In the face of the strong questioning of the major captain, Falkenhausen was also a little hairy.

For a while, he was like a trapped beast, with red eyes, ignoring the old feelings between each other, glaring at Liu Yun viciously, hoping that this guy could explain honestly, otherwise he wouldn't want to leave the warship alive.

Commander Liu may have been really afraid of him, so he had to remind in a low voice, "Please don't get me wrong, it's our intelligence officer, who exchanged countless blood for the intelligence."

"Is it Japan?" Falkenhausen and Captain Major were stunned.

In the past few years, hasn't Germany been making arms deals with China, how could it come out of Japan, after all, His Excellency Hausen is more well-informed and has thought of all kinds of possibilities, but in the end he has to admit that I am afraid that Japan is the majority.

It is no secret that Germany abandoned China and turned to form an alliance with the Japanese, not to mention that the Japanese devils still swore that they would send troops to Southeast Asia.

Therefore, it is inevitable that Germany will export 240-mm mortars to Japan.

Seeing the pale and weak Falkenhausen, the captain's heart was also cold, and he scolded with some indignation, "Are those people in Berlin all pigs?" The 240-mm mortar guns were shipped to Japan, and now even Huaxia knows about it, not to mention Britain and France and other countries, isn't this a child's play with the lives of our soldiers? ”

Liu Yun laughed so hard that his stomach hurt.

The 240-mm mortar gun was really exported by Germany to Japan, and there was only one one, and the Japanese devils themselves were very precious, and they planned to imitate them and equip them with heavy artillery brigades, so how could they leak secrets to outsiders.

But nothing is absolute.

At least, from the point of view of General Hausen and Mr. Major, they really think that the Japanese leaked secrets, otherwise how did Commander Liu know, it was a 240mm mortar gun and a 170mm heavy gun.

"The hateful Japanese devil, both insatiable and cowardly".

Falkenhausen secretly cursed in his heart, and it seemed that he had to report to Berlin as soon as possible, that the Japanese could not be relied on at all, and that if there was any new technical cooperation in the future, they would have to refuse, otherwise they would send it to Britain, France, and other countries.

When General Haosen was stupid, Mr. Major, who was smart and self-motivated, hooked up with Commander Liu.

Speaking in broken Chinese, he briefly introduced himself, "Dear Mr. Liu, it's a pleasure to meet you, my name is Wilhelm Herrac, I was born in Hamburg, Germany, and there is an overseas Chinese restaurant next door to my house, so I like to eat Chinese food and speak Chinese since I was a child."

Foreign buddies who can like Chinese food and Chinese are all good comrades.

Liu Yun couldn't help but feel good, so he shook hands with Herac very friendly, and took a closer look at this guy by the way, he was about thirty years old, and he should not have participated in World War I, but the German Wehrmacht had only recently expanded, but anyone who can be a major now is basically either rich or noble.

Commander Liu asked quietly, "Herak, this mission to China is coming to an end, I wonder if you have ever thought about what kind of souvenirs you will bring with you when you go back to Germany?" ”

Major Herac was immediately overjoyed, and when he was about to answer, he heard a dry cough from Falkenhausen, and his body couldn't help shaking, pretending to be stereotyped, "I'm sorry, please forgive Mr. Liu, I am an upright soldier, and I obey the orders of my commander in all actions, please forgive me for not being able to answer this."

Liu Yun smiled, a little disapproving, and went to enjoy the scenery by himself.

His Excellency Haosen also seemed to be busy, so he didn't say much, but glanced at Mr. Major very sternly, and then ordered this guy to do some chores, until this guy went away, and then whispered to Commander Liu, "Brother Yicheng, what to transport back, Berlin has already made arrangements."

Liu Yun smiled silently, but sneered in his heart, what kind of bullshit Berlin arrangement, not a part of the bureaucrats, under the banner of Berlin, engaged in some smuggling activities, dared to bet with the upper of the shoe, Falkenhausen also accounted for some shares.

This guy quietly suggested, "This major is good, his heart is more lively, you see if you let him stay in Huaxia, there are some inconvenient things in the future, let him do it."

Falkenhausen's eyes froze, as if he was surprised, he thought about it for a long time and didn't really understand what was inconvenient for the major captain who had just arrived in China to do.

Seeing the bewildered Lord Haosen, Liu Yun was also a little dumbfounded, so he had to explain in a low voice, "This 170mm gun, whether it is for Germany or for China, is a vital weapon, so it must not be leaked, and the best way is to let Major Herac also participate."

"Involved, engaged in what?" Of course, it is involved in the transportation, installation, commissioning, and later imitation of artillery fire.

Falkenhao suddenly realized at this time, yes, the Japanese military department is like a "toilet door", it is casually pushed away, there is no secret at all, and Liu Yun's reminder is also at the right time, and the Nanjing Nationalist Government is also famous for its "casualness".

If the Germans had not intervened in time, these weapons would have been on the tables of Britain and France tomorrow.

The 170-mm heavy gun, which Germany has just developed, is still in the top secret range, so how to keep it secret? The only way to do this is to silence everyone involved.

Historically, the dead are the safest.

Is it necessary to kill all the crew members of the destroyer? Of course not, because it was easier for the Nanjing government to leak secrets, so these German soldiers would not die in vain, so Falkenhausen decided to adopt Commander Liu's method.

Liu Yun and Falkenhausen glanced at each other and laughed silently.

Everyone is a good buddy after all, and there are some words that don't need to be clarified, and then the two of them didn't pay attention to the image, so they left the destroyer shoulder to shoulder, so that the stereotypical and dogmatic German sailors broke a lot of glasses.

173mm howitzer, is it really so heavy or?

Liu Yun returned to Kong's villa, lay on the Taishi chair, squinted his eyes slightly, and carefully pondered the mysteries.

Artillery fire, known as the "god of war" by the military circles of various countries, because in terms of warfare, which army has the most artillery fire, then they will be favored by the god of war, and finally have the greatest chance of victory.

How powerful is a 173mm heavy gun?

The muzzle velocity of the shell is 925 meters per second, the ordinary shell is 68 kilograms, the firing range is 22 kilometers, the effective killing range will be more than half a football field, if the 23 kilogram light bullet is fired, the range will be as high as 29.6 kilometers, if it is not only 80 rounds per hour, then the 150 mm and 120 mm heavy guns have to face the problem of unemployment.

Heavy artillery has always been an artifact of the town.

During the eight years of the all-out war of resistance, no matter whether it was the Japanese army or the Chinese army, except for large-scale battles, there were no artillery of more than 100 mm at all.

Most of the artillery weapons in the Asian army units are 70 mm infantry guns, or 75 mm short-barreled mountain guns, and even in many units above the division level, it is rare to even be equipped with 75 mm long-barreled field guns, let alone more than 150 mm cannons, which is simply a fantasy.

In the entire Japanese army artillery system, the only practical 240 mm cannon was still imported from Germany, and when used, there were still great limitations, and it usually could not be too far from the railway line.

Therefore, the 170 mm heavy artillery group, once it has formed a scale, is not afraid of the pig tactics of the Japanese devils at all, in addition to not being able to air defense, even all ground creatures meet it, it is a terrible disaster, even the US army, which is known for its local tyrants, also favored this gun in the late stage of World War II, and many troops were directly equipped with it.

The German military named this type of heavy artillery "French lady", which means some kind of moving and terrifying creature, of course, there is also the meaning of mocking the French Miss 75, because Miss 75 can fire 38 rounds of 75mm shells per minute, which made the German army suffer enough in World War I, that is, the power of the shells is less.

In addition, during the First World War, the Germans also developed several types of train guns, some of which even exceeded 300 mm, with a maximum range of 131 kilometers.

Therefore, the newly released 170-mm gun was pinned on infinite reverie and hope by the German army.

Liu Yun suddenly came to his senses, he considered the problems of planes, tanks, and steel, railways and armaments, and even transportation and currency, but ignored one problem, that is, heavy artillery fire.

For example, the training manual of French officers clearly stated, "Artillery is an indispensable part of a complete army, and it is impossible to imagine a battle without the participation of artillery."

The German army's 170-mm heavy artillery was really a timely rain, which greatly filled the gap in China's heavy armament.

Liu Yun hurriedly communicated with Zhi Brain and asked it to simulate the 173mm heavy gun immediately, fortunately, all kinds of components are archived, and as for problems such as assembly, even the manual can be dispensed with.

In three minutes, Zhi Brain got the new German cannon and invited Liu Yun to visit immediately.

Commander Liu explained to Kong Yuling that in the next two or three hours, please don't disturb him easily, because he has to retreat and cultivate, and if he is injured by his unconscious counterattack, he will not be responsible.

Liu Yun was in the study, his eyes were closed, and his appearance looked no different from cultivation, but in fact, he entered the virtual space of the brain.

After this guy went in, he found that the evolution of the brain is also very fast, and he has not entered the virtual space of the brain for half a year, and the world has already been turned upside down, and the interface is no longer a small mechanical manufacturing room, but an endless prairie, which makes people feel like they are in the scene, and they can faintly smell the fragrant fragrance of the grass.

If it weren't for Commander Liu's ability to perceive the difference between the outside world and reality, he would have thought that he was already in an independent small world.

Commander Liu was too busy to think about the changes in the virtual environment, so he directly asked Zhi Brain to show the 173mm heavy cannon, only to see that in the boundless grass, a glittering elf flew in, holding a small magic wand, and waved it lightly in the air, and one cannon appeared immediately.

Then the elf flew towards Liu Yun.

The elf is a miniature little beauty, only more than three inches tall, a pair of butterfly-like transparent wings, gently flapping in the air, a dreamy and small princess fashion, faintly moving, she is holding a magic wand the size of a matchstick, looking at Commander Liu with a smile, making him feel a sense of déjà vu.

Liu Yun asked silently, "You are Zhibrain Dick."
