Ferdinand didn't know much about technical things, he looked at the round and slender torpedo model in his hand over and over again, and muttered with an incredible face: "Eight thousand meters of range, can be launched on the surface, sail in a straight line, huge charge, any ship will be hit by one, unsinkable or seriously injured, this thing is terrible, torpedoes will become a nightmare for all ships." ”

"No, the torpedo is not the nightmare of ships, the mine is the nightmare of all ships, and we can still see the wake of the torpedo now, which can be predicted in advance, but the mine is not like this, it is a silent killer, only when it explodes, you will find its existence, and the mine is the real underwater demon."

"Mines, the kind of iron guy with a lot of tentacles floating in the sea? What is so scary about them, as long as the observer keeps an eye on the surface of the sea, there is no need to guard against that thing at all. Ferdinand carefully placed the torpedo model in his hand on the table, and said disapprovingly as he carefully straightened it.

In 1898, the mines had not been developed in large quantities, and the first ones to appear were floating mines, and anchor mines also appeared, but they did not attract people's attention until the Russo-Japanese War, after the two sides used a large number of mines, this large killing weapon that could pose a huge threat to ships attracted people's attention.

Because the floating thunder floats on the surface of the sea or floats at a certain depth below the surface of the sea, there is a problem that it runs around with the ocean current, and it is easy to be seen by the observers on the ship, and it is very easy to detonate.

The anchor mine is to connect the floating mine to the anchor on the bottom of the sea with a steel cable, and half-float at a position of a few meters from the sea surface, so that there is a better concealment, and the general observer can not see it, but the demining of the anchor mine is also very simple, with a steel cable connected between two ships, and the anchor mine is dragged out of the sea.

This is also the reason why Ferdinand did not take it seriously with mines, because the mine technology of this era was too primitive.

Gao Hongsheng smiled mockingly at Ferdinand, reached out and took out a pen from the inner pocket of his jacket, climbed on the table on a piece of white paper, and slowly sketched out a simple structure of a magnetic mine with the pen.

During World War II, the Germans' magnetic mines were not complicated, and they can be described very simply, but people did not expect that the magnetic properties of ships would be used, and the lack of understanding made magnetic mines show their skills.

At the same time, magnetic mines are very simple to manufacture and easy to remove, but it would be tragic not to be familiar with their properties.

Because the magnetic mine is a sinking mine, the original method of dragging the anchor mine out with a steel cable is invalid, the sinking mine is sitting on the bottom of the sea, and it is easy to be covered up by other items after a long time, which increases the difficulty of discovery, and the effective time of the mine is as long as twenty or thirty years, cheap, long-lasting, difficult to eliminate, and the threat is great, which makes the mine a strategic weapon of the navy of a poor country.

On the one hand, the mine relies on a strong pressure wave to impact the hull to cause damage, because the expansion coefficient of the water is more than that of the bottom of the air, a strong pressure wave will be formed after the explosion of the mine, and when this pressure wave exceeds the maximum pressure that the hull can bear, the hull will burst, and the radius of destruction is generally 5 to 6 meters.

On the other hand, the bubble pulsating pressure injury, that is, after the mine explodes in the water, the air bubble formed repeatedly acts on the hull, causing the skeleton and steel plate of the hull to be repeatedly compressed and stretched to produce bending and deformation, not to mention the result.

The same is true for the damage caused by torpedoes attacking ships below the waterline, especially the use of air bubbles to deal with submarines with depth charges, of course, this is also the main reason why aerial bombs with the same charge cannot compare with mines and torpedoes with the same charge, and the damage to ships is greater.

"What are you drawing?" Ferdinand's eyes didn't stare at the paper at all, but looked at Gao Hongsheng's pen and asked curiously about the pictures on the paper.

Gao Hongsheng buckled the cap of the pen, threw it on the table, and then pointed to the sketch and said: "This is a new type of mine, a magnetic mine, its function is that when the ship passes over it, it will explode on the bottom of the sea, and then the ship on the water will be thrown off the water like a building block, and then smashed back into the sea, and then sank to the bottom with the keel broken or the hull rupture." Ferdinand, note that it is sunk underwater, and your minesweeper will not be able to sweep away such mines at all. ”

Gao Hongsheng did not boast at all, during the Second World War, in September 1939, Germany laid magnetic mines in the waters from the mouth of the Thames River in Britain to the vicinity of Hambel, and after using old minesweepers to clear mines, 17 warships were sunk by mines.

Ferdinand listened to Gao Hongsheng's words, but he didn't have time to look at any fountain pens, and looked at the sketch on the white paper in front of him in surprise, as if looking at a demon.

The picture shows a long cylinder with a simple hydrometer drawn at one end, a Gaussian gauge at the other, and a battery in the middle, connected by several wires.

The water pressure gauge is equivalent to a cutout switch, only when it is put into the water with a certain pressure will be turned on, the Gaussian measuring instrument is equivalent to the detonation switch, when the ship full of magnetism passes through the top of the Gaussian measuring instrument, it will make the magnetic needle of the measuring instrument offset, and the entire line will be connected, and then the whole line will form a loop to energize the electric detonator and detonate the mine.

Such a simple drawing, Archduke Ferdinand understood it at a glance, but when he saw the huge charge, he was indeed frightened, and it was clearly marked that TNTEC aluminum powder was 500 kilograms, what ship could resist its explosive power?

Once this kind of mine appears in the ocean, it is definitely a demon on the bottom of the sea, you don't know where it is hidden, and you don't know when it will be encountered, people are always the most afraid of unknown death, this kind of sudden feeling of death will make everyone on the boat feel deeply nervous and afraid, these two feelings will be very tired after superimposing, until you are driven crazy.

Ferdinand raised his head to look at the smiling guy in front of him, gritted his teeth and said, "Gao, you are a devil, an undersea demon in the eyes of all captains who want to swim in the sea, and they will curse you to hell forever." ”

Gao Hongsheng shrugged his shoulders and smiled indifferently: "I invented Tianjing Roulette in Tianjing, China, leaving a bullet in a revolver, and then everyone takes turns to shoot themselves, this is a gamble at the cost of life, but it seems to be very popular now, where they call me Devil Gao, I once said, God created human beings, but human beings kill each other, do you still blame God?" ”

"Are you the devil high? Are you the devil who invented Tenkyo roulette? Ferdinand jumped up and pointed at Gao Hongsheng and shouted.

Gao Hongsheng made a quiet gesture, and then said indifferently: "Hey! Quiet, quiet, a gentleman shouldn't be so excited, what's wrong with me being the devil? I love the name. This name is much better than Angel Gao, how domineering. ”

"Oh! Don't you know that the name Devil High is famous? You put an end to the duel with a pistol between gentlemen, but invented a new duel that is even more cruel, leaving one's fate to God to decide, and now if a person feels insulted, then he will propose Tenkyo Roulette and leave his fate to God to judge right and wrong, do you know how many people have died in Tenkyo Roulette since the introduction of roulette in Austria-Hungary? Of more than 300 people, I visited the Tianjing Roulette twice, and watched two people smash their heads with revolvers, and you made me lose a hundred pounds, but I liked it. Hahaha. ”

"It's an honor to receive your compliment, ha, I didn't expect my name to be so popular." Gao Hongsheng also likes the name of this devil Gao, in this troubled world, the devil and the angel are just a matter of thought, but the devil lives much more comfortably than the angel, the devil does not need to abide by the rules of this world, it can do whatever it wants, and do it willfully.
