Xu Jun sat up from his small, but absolutely soft and comfortable bed, and he fumbled in the dark for a long time before finally finding the small overhead light switch on the wall next to him. The fluorescent lights flickered a few times, and then a bright, soft light filled the small captain's quarters.

Xu Jun sat on the head of the bed, looking at the simple oak panels on the wall at the end of the bed in a daze. A few months ago, Xu Jun was still thinking about whether to go to Norway to visit the U-boat museum, and now he is lying alive on the bed in the captain's room of a U-boat, and this is not the kind of antique that has been renovated and retouched, but a real powerful killing machine. As soon as he thought of this, Xu Jun deeply felt the wonder and incomprehension of fate.

The U37 is a Type 9A ocean-going submarine that has only been in service for less than two years, she is still almost brand new, and the feeling of dirt and dilapidation on those old submarines cannot be found in her at all, and after three ocean cruises, she still maintains that neat and clean, and all the equipment is still as sparkling as when she first launched the water. From this point, it can also be seen that Gisel is indeed a very capable captain, at least he is a captain who cherishes equipment very much, and Xu Jun has a very good feeling for the young captain from the maintenance of this battleship.

Although in Xu Jun's eyes, she can be said to be very primitive, but in this era she is the crystallization of the highest technology in Germany at that time, she represents the most advanced submarine technology and design level of this era, she is the pride of Germany and the nightmare of all enemies at sea.

The U37 crew is full of energy and confidence, believing that in their own hands this submarine can be taught to any offending enemy at any time and in any place. They all believed that in their hands, this submarine would be able to create great feats that their predecessors dreamed of, and they themselves would be praised and envied by their families and friends because of these feats.

These young sailors were not unaware of the dangers they might face in their quest for honor, in fact, only these three Type 9A ocean-going submarines have survived, and the remaining five have all been killed in the rough waves during the two years of fighting, and two of the five submarines have been killed in battle.

Those comrades-in-arms who once had the same dreams as them are now sleeping deep under the sea, but that doesn't change their love for their cause. They believe that it is worth taking any risk and pain for the sake of their homeland, and they are fighting for it. Although they did not fully understand Hitler's strange reasons for war, since the war had already happened, every German soldier should fight hard for the victory of the motherland, which is the responsibility of the soldier and the meaning of the existence of the soldier.

Since you are a sailor, you should be mentally prepared to die in the sea. As the saying goes, the sea is the best place for a brave sailor. A sailor should die in the sea instead of in his bed at home, and it is a sailor's dream to be able to sleep forever in the bosom of the sea he loves. These were the answers that those sailors gave to Xu Jun. Maybe because Xu Jun is not a sailor, so he is a little difficult to understand the romantic ideas in these answers, but Xu Jun feels that this should be the way of thinking of men who fight with the sea, which is in line with the character of these brave sailors, which makes people feel blood boiling when they think about it.

Xu Jun looked at the few small indicator instruments on the wall of the captain's room, now the submarine is moving at a speed of four knots under thirty meters of water, it seems that it is now passing through the patrol area of which plane or patrol boat, the clock on the wall shows that it is now three o'clock in the morning, although it is still night, but the moonlight on the sea is much brighter than he imagined, and the submarine will be easily spotted by those patrol planes or ships when driving on the silver glittering sea surface illuminated by the moonlight, especially in the narrow sea of Denmark and Norway. The fact that the submarine must act so cautiously before entering the North Sea is the conclusion agreed upon yesterday after careful discussions with Gisel during the day.

The captain's room is the best room on the whole boat, of course, compared with the luxurious captain's room of those huge surface ships, it is extremely shabby, but under the hard and cold hull of this more than 1,000-ton ocean-going submarine, the living space of the crew is unimaginable, and being able to have this private space here is the embodiment of the captain's supreme authority on this submarine.

The captain's cabin was very clean and tidy, and it was clear that Giselle was a very tidy and disciplined person. The surrounding hard steel walls are inlaid with an oak cladding and painted with a pale brownish-yellow varnish. The bed took up almost half of the room, and next to the bed was a simple metal desk with a wooden top and a velvet tablecloth. Above the table is a row of wooden filing cabinets, which are inlaid in wooden cladding and painted with the same color varnish as the walls. On the other side of the table is a chair fixed to the floor. A tall storage cabinet occupies half of the wall, and on the side is a small wall-mounted bookshelf. Then there was a chart frame, but now there was no chart in it, but Gissel's private photograph was pasted there. Underneath the chart frame is a small strip sofa. In one corner of the room there is even a small washroom with a beautiful porcelain bucket and a faucet. There was also a small shelf for toiletries, an oval-shaped mirror embedded in the wall above the bucket, and a cork guard was sandwiched behind the mirror to prevent it from being shattered during the battle. The whole room brings a warm and safe feeling, and Xu Jun is sincerely admired by the meticulous attention to detail of the German designer.

Xu Jun got up from the bed, and he tried to put on the shiny leather boots with one hand. These boots were made to order when he was in Poland and are made of the finest lambskin with elastic skin, so it is easy to slip your foot into these calf-hugging boots with one hand. Because it was in the special living environment of the submarine, he didn't change into any pajamas when he slept, and it was too troublesome to take off the military uniform, so he only took off the golden marshal's uniform, and went to bed without even taking off his military pants, so that it was not only convenient to get up after getting up, but even if there was an accident and he would not be disheveled and embarrassed when he escaped. To be honest, Xu Jun cares a lot about his military appearance and discipline, and he pays great attention to his appearance.

Xu Jun untied the lanyard that held his arm in place, put on the marshal's uniform despite the pain, and then re-fastened the injured hand to his chest. After doing this, Xu Jun carefully checked up and down, then put on his military hat and walked towards the narrow wooden door, he corrected the military hat and the knight's iron cross in the small mirror next to the door, and then opened the door and walked out.

"Ahh Your Excellency the Marshal. Salute. ”

The two commandos standing guard at the door were startled by the sudden opening of the door, and when they saw Xu Jun, they hurriedly stood up and saluted with their guns.

"Oh? Why are you guys here, didn't I say that there is no need to stand guard on submarines? Xu Jun felt very strange, how could these two commandos disobey their orders, when they first got on the submarine, Xu Jun had ordered not to add a guard at the door of his room, the aisle in the submarine was already very narrow, and then stuffing two commandos who were as tall as a cow in such a narrow aisle was simply creating chaos, not to mention that the captain's room was in the position between the officer's room and the command cabin, and the commandos would have an impact on the normal operation of the submarine if they went there. These few people have already caused a lot of trouble to this submarine, and they really can't make any impact on their work.

"Report to the marshal, this is Captain Gisell's order, and he says that in any case a marshal should have guards standing guard in front of the door. No matter where you are, you should abide by the traditions of the German army, especially on the ships of the navy, and the difference in rank must always be remembered. He couldn't watch a marshal not be treated like a marshal on his ship, and it made him feel very sorry and guilty that he couldn't do that in life, and it would be too unreasonable to simplify the etiquette of a marshal in other respects, so he ordered us to keep a vigil for you here. He said that he was the supreme commander on this ship, and that you had to obey his command in name, so we could not disobey his orders. Colonel Dougan also agreed with Captain Gisell, saying that if we disobeyed the captain's orders, the captain had the right to throw us off the boat, and that we had to obey his orders so that such a terrible thing might not happen to us. If this makes you angry, we are willing to accept any punishment you may have on us. Your Excellency the Marshal. An SS commando sergeant looked up and explained proudly.

"Haha, I don't think it's just the captain's order, you actually think so in your own hearts." Xu Jun said with a smile as he looked at the two tall commandos.

"Yes, Your Excellency. We believe that you should show your status and enjoy proper etiquette at all times, this is the tradition of the German team, this is the recognition of the merits of heroes and warriors, and there must be no slack. The sergeant replied without hesitation.

"Really? But that might affect the work of the rest of the people on the submarine, and I don't want anything to happen to this submarine because the officers are stuck in the aisle by two of my guards, hahaha. Well, now that I'm up, you don't have to keep vigil, go to your place and rest. Don't contradict me, this is not a suggestion, this is an order. Xu Jun said with a smile.

"Ah, this ...... Yes, my marshal. After the two commandos looked at each other, they had to salute Xu Jun again, and then turned around and walked in the direction of the command warehouse.

They were placed in the officer's quarters, at the back of the command room. This has always made Xu Jun feel a little uncomfortable, those submarine officers gave up their beds to sleep with their attachés, and they ran to the soldiers' cabin to huddle with the soldiers, or simply went to the torpedo cabin to work on the bunks. But after all, this is an ocean-going submarine, the living space has been greatly improved, and there is still some spare space, if it is the kind of small attack submarine that is only 500 tons, it really can't be crammed into nine people at once.

Xu Jun turned around and found that the two commandos had already drilled through the small round pressure-resistant hatch that had entered the command cabin. On German submarines at that time, only the doors on both sides of the command cabin were round pressure-resistant doors, and the doors on the other compartments were ordinary rectangular waterproof doors, which were convenient for the crew to move between these compartments. Xu Jun decided not to drill that small round hole yet, he put his hand in his trouser pocket and walked slowly in the direction of the bow of the boat.

The main color of the interior of the German submarine was the same clean snow white as the interior of the tank, and the snow-white walls were studded with all kinds of pipes and circuits, which could be said to be the veins of the submarine, and any problem with any of them could bring disaster to the submarine.

Opposite the captain's room are the radio room, underwater listening room and other combat units, which are small and divided spaces, except for the radio room and a wooden door, which are usually only hung with a thick curtain. The listener had obviously heard the conversation between Xu Jun and the commandos, he opened the door curtain, and when he saw Xu Jun coming over, he quickly stood up and nodded to Xu Jun. Xu Jun smiled at him and nodded, then waved his hand to continue his current work, and the soldier nodded respectfully again, then sat back in his seat and turned his cāo handle again to listen to the movement outside the boat.

Now the submarine is diving underwater, and at this time it is using an electric motor, so there is not much noise. Xu Jun felt a headache when he remembered the roaring noise of the diesel engine when he sailed on the water yesterday, but he had nothing to do about it, this is already the limit of submarine technology in this era, and it is very difficult to change this according to the current technology, although there are several ways to reduce this noise a little, but the cost will increase a lot in comparison and the effect is not obvious, and the submarine surface noise at this time does not affect her operations, so Xu Jun also gave up the idea of reducing the surface noise of the submarine.

Since the submarine has been diving for a long time, the air inside the submarine is really difficult to compliment. The pungent smell of diesel oil mixed with various human smells made Xu Jun feel unbearable, and the gradual increase in carbon dioxide and other harmful gases made the air in the boat even more turbid. The air pressure inside the submarine also continued to rise with the increase of depth and the emission of those gases, which made people's eardrums feel uncomfortable for a while.

When Xu Jun passed by the door of the radio room, he looked in through the transparent round window on the door. It seems that the most comfortable thing in sneaking is the dispatcher, and now he is curled up on the bed with a military blanket and sleeping soundly, it seems that this young man is really tired, thinking about the pile of telegrams he receives every day, Xu Jun knows that this young man is definitely busy in the past two days. Xu Jun left the window lightly, fearing that he would alarm the reporter inside, and then walked down the aisle towards the officer's rest area.

Officers' rest quarters are only available on such ocean-going submarines, and other submarines have only a small officer's room. In fact, this is a space that has been divided for the use of officers, with a beautiful corner sofa and a normal round table, where officers can rest, chat, play cards and smoke when they are not on duty, and this is also the dining room for some junior officers, they eat at that round table, and those senior officers eat in the officer's room. There is a strict hierarchy in the German team, and there is no special reason why the senior officers will not eat at the same table with these junior officers.

There are now several officers sitting on the couch in the officer's rest area, probably waiting for the shift to be handed over. A warrant officer was reading a book with relish, two ensigns were playing cards in boredom, and a lieutenant was writing something on a piece of paper with a cigarette in his mouth, and the excited look on his face might be writing a love letter to some pretty girl.

Xu Jun walked over gently, but his leather boots still made a lot of noise on the metal floor. The lieutenant was startled, and he looked up in the direction of Xu Jun, only to startle him. The lieutenant jumped up from the couch like a spring. The other three were taken aback by the suddenness of his action, and they put down their contents and turned their heads suspiciously to look in the direction that the lieutenant was looking at excitedly. Then they also stood up violently like the lieutenant, and looked at Xu Jun who came over with a smile open in surprise, speechless.
