Nakajima and Inoue standing on the deck saw two waterlines on the sea, but as landlubbers, they didn't understand what they meant.

The two of them looked strange, and loudly beckoned the people around them to take a look at the two waterlines that were about to hit the merchant ship.

And the elites of the Black Dragon Society are also strange, I don't know what kind of fish it is, swimming so fast, and flying straight towards the steamer, if it hits the ship at such a fast speed, it will not be broken?

The two of them led many Black Dragon Society members who were curiously pointing at the waterline, when they suddenly heard a Taiping sailor next to them shouting in fear: "It's not good, it's a torpedo." ”

Then, just as the landlubbers of the Black Dragon Society were guessing what kind of fish the torpedo was, they heard two loud bangs, and everyone standing on the deck fell to the deck as if they had been pushed by something.

Nakajima and Inoue slowly straightened up at this time, looked behind them, and couldn't help but be frightened, because this thousand-ton merchant ship was hit by two torpedoes in the middle keel of the ship.

Two torpedoes directly blew the merchant ship into two sections, and a large amount of seawater poured directly into the ship's cabin, and hundreds of Black Dragon Society elites who were resting in the ship's cabin were directly submerged by the seawater, and many unlucky elites were directly pulled to the bottom of the sea by the sea.

Because the merchant ship was so damaged, the two merchant ships were barely connected together by a little metal in the middle, because of the huge gap in the seawater poured in tons of seawater. Soon the inclination of the two ships was too large, and it looked like they were about to sink into the sea.

Nakajima, who was lucky not to be flooded by the sea, and a group of Black Dragon Guild members were trying to find a way to free the liferaft on the deck, because of the damage caused by the shaking of the hull, these people were not professional sailors, and it was difficult for them to put down the life raft.

Just as Nakajima and Inoue were desperately trying to rescue the raft, they saw two more waterlines flying out of each side of the merchant ship under the sea not far away.

Nakajima and Inoue couldn't help but widen their eyes, and even the action of rescuing the life raft stopped, and they watched the four waterlines rapidly approaching the bow and stern of the boat.

Their minds were blank at this time, and they just thought subconsciously, why did they come with four more torpedoes, their own ship was about to sink, whether they could escape or not is two words, why did they waste so much to launch four more torpedoes to attack this merchant ship that was about to sink, isn't it a waste to do so?

This is the thinking of the Japanese military and civilians who are accustomed to living a poor life, because of the lack of resources on the Japanese island, the Japanese have developed the fine character of diligence and simplicity and thrift since childhood, and even at the moment when they face death, they still cannot forget this good habit that they have cultivated since childhood.

However, the torpedoes would not deliberately deviate from course because of their frugal habits, but when they heard four loud explosions, Nakajima and Inoue felt as if their bodies had suddenly been thrown into the air.

The people also fainted directly, but before they passed out, they seemed to see each other's bodies spinning and falling towards the sea.

A thousand-ton merchant ship that had been hit by six torpedoes was smashed to pieces in this way, not to mention a thousand-ton merchant ship, even if it was a giant ship of 10,000 tons, if it was hit with six torpedoes at the same time, it would only be sunk.

In this way, the 1,000-ton merchant ship Chunyu Maru, which was carrying more than 500 Black Dragon Society elites from Japan to Lushun, China, was blown to pieces and quickly sank in China's open sea.

Because of the powerful torpedo attack almost at the same time, the merchant ship sank to the bottom of the sea without even sending the slightest distress signal, along with the 500 elite members of the Black Dragon Society and dozens of sailors of the Taiping Society.

When the thousand-ton merchant ship was sinking rapidly, three submarines slowly rose on the sea not far away. It was Li Tie who bought those submarines from Germany.

The three submarines looked around the merchant ship for half a day, and after discovering that there were no sailors alive, they sank into the sea again and disappeared.

And in one of the submarines of the three submarines that sank into the sea, the German instructor Karl patiently explained to the group of Chinese sailors beside him: "See, this is the dangerous force of the submarine, this is the dangerous force of the torpedo, don't say that this is just a thousand-ton merchant ship, it is a 10,000-ton giant ship, if this torpedo just hits the vital point, this giant ship will only have the fate of sinking."

"But Instructor Karl, as you said, one torpedo is enough to deal with such a thousand-ton merchant ship, why do you have to fire two at the same time?

And what I also don't understand is why the submarines Donghai No. 2 and Donghai No. 3, which were ambushed nearby, each fired two torpedoes to attack the merchant ship, since they had already broken into two pieces and were sinking merchant ships.

Do you want to waste more torpedoes so that my young master can buy more torpedoes from your Germany? A submariner who was obviously from Li Tie's hometown asked.

"Oh my God. In the words of you Chinese, the dog bites Lu Dongbin, I don't know the hearts of good people, I am your instructor, I am teaching you how to attack merchant ships through actual combat.

After this battle, you are truly qualified submarine officers, and you can see how timely and correct your launch order was.

Even if it's me in command, that's the level. As for why we fired two torpedoes, it was because the ship was in constant motion, and firing two torpedoes would greatly increase the difficulty of the enemy's evasion, and at the same time increase the probability of us hitting the enemy.

This is the standard firing tactic that we have written down when we were learning submarine attacks, and you can question it, but you must respect it in action, unless one day you can come up with a more cost-effective tactic than firing two torpedoes at once.

Of course, through today's battle, I think the cadets here have seen the danger of our German most advanced torpedoes, so I hope that in the future, when you are in a high position, you must not forget to use our torpedoes produced in Germany. At this time, Karl did not forget to instill in his students the benefits of German products.

"But Instructor Karl, you haven't explained why three submarines came together to attack this merchant ship, you also saw it, it is enough to deal with him, our Donghai No. 1.

But this time we dispatched three ships, not counting the one that was hiding in the mouth of Arthur. Are we wasting resources by doing this? A student from the Lingshui base asked.

"Oh, dear cadets, I am showing you the concrete implementation of the greatest submarine tactics of the century, the wolf pack tactics.

The inventor of this tactic is none other than your young master Li Tie. I'm verifying his tactics, so how can you say I'm wasting your torpedoes?

You know, we are only dealing with one merchant ship today, but in the future, you may be dealing with ten ships, dozens of ships, and the attack power of just one submarine is limited.

The cooperation of multiple submarines can not only increase the enemy's losses very well, but also confuse the enemy's line of sight, increase the enemy's pressure, and infinitely increase our chances of survival safely leaving the battlefield afterwards.

Oh my God, this wolf pack tactic is simply the ultimate tactic of submarines, and the strongest tactic, he was born for submarines, for our German Navy.

I really don't understand how Li Tie's head grows, and such a tactic that has gone through the past is actually from the hands of a layman like him. I really admire the five-body throw. Carl was also very emotional.

"Then my young master's wolf pack tactics let you learn in vain, didn't you take a big advantage?" Another submarine cadet from Li Tie's hometown asked.

"Just kidding! Is Li Tie the one who can make people take advantage? For this tactic, our forty naval instructors were forcibly rented by Li Tie for another five years.

And the most excessive thing is that Li Tie is holding a copy of the latest U-shaped submersible design designed by our German engineers, plus a copy of the latest diesel generator technology in exchange for a hundred of our German submarines, he is really an elephant with a big mouth. Carl said exaggeratedly.

"Instructor, it's the lion who has opened his mouth." One of the trainees immediately corrected Carl's mispronunciation.

"Of course, I know that it was the lion who opened his mouth, and I just used it to express my indignation at Li Tie's greed.

No wonder within a few years, he became the richest man in the world. His ability to make money is really not small. Even the black money of allies is earned. Carl expressed strong contempt for Li Tie, a black-hearted businessman.

"Then Instructor Karl, have you agreed to the price of my young master?"

"Of course, I can't agree. Are we resentful? We had economists, and after much deliberation and friendly negotiation between the two sides, we finally settled the deal at the cost of providing you with 20 of the latest submarines for free and at the cost of helping you train 500 submariners. How, are our Germans very strong in bargaining? Carl said happily.

In fact, where do these students understand the importance of submarine design drawings and engine design drawings, anyway, these students laugh at the Germans in their hearts.

Because they spent a lot of money just for two drawings and one tactic. Therefore, both the trainee and Carl are proud of their bosses and intend to complete the tasks assigned by their bosses conscientiously.

Carl saw the happy smiles of the students, and he smiled happily: "Dear students, I don't deny that I am the bargaining chip that is fulfilling this transaction.

I believe that after this good live-fire exercise, the first batch of 100 of your trainees will soon become qualified submariners.

And your young master Li Tie will definitely rest assured that the most advanced diesel generator technology will be handed over to us in Germany.

With this epoch-making technology, our German-made submarines will dive deeper, carry more torpedoes, and go faster and farther.

But the thought that we in Germany have to buy back these technologies from our own engineers in Germany makes my heart ache.

Oh God, I can't wait to get back to Germany to meet the newest submarine. But unfortunately we still have a mission to complete, let's go, let's continue our mission. ”

"But Instructor Karl, we don't have any enemies on the sea anymore, where are we going to do our internship now?"

"Remember, as a submariner, as long as there is an ocean is a field for you to walk, I plan to take you to the Sea of Japan for a walk, and by the way, taste the unique Hokkaido lobster."
