"Is there really a cave around there?" Chen Guan squatted on a large reef on the shore and chatted with an old fisherman next to him.

"You can't go wrong. I was still young that year, how old was I? Not as big as my youngest grandson anyway. The old fisherman smiled and glanced at his thirteen-year-old grandson who was turning over the fishing nets not far away, pinched the victory brand cigarette handed over by Chen Guan, did not smoke it, and sniffed it directly on his nose.

Seeing this, Chen Guan gave the remaining half of the box to the old fisherman.

The old fisherman was not polite, and took the box of cigarettes with a hand as dry as the bark of a tree. After looking at it carefully for a long time, except for the pattern of two fingers pointing upwards on the right hand on the top, I couldn't understand the other words and patterns. But the old fisherman could tell from the delicate red hard-shell packaging that the cigarettes were not cheap.

After flipping and looking at it for a long time, he stuffed it into his personal pocket with satisfaction, squinted his eyes and smiled at Chen Guan, who had been waiting patiently: "Look at my surname, I always forget things." ”

He stretched out his hand and pointed to the sea in the distance, turned to Chen Guan and said, "Do you see that Mantou Mountain in the distance?" It's the one that looks like a steamed bun. It was seen that it was quite smooth on the outside, with no holes or seams, but it was very different on the inside. His eyes were full of longing, and he sighed and thought of his distant past.

"That year, a few of us were playing at the beach. Suddenly, the sea receded. I've never seen the sea go back so much, even in several major droughts, and I've never seen so much less water. As soon as the sea receded, there were a lot of good things left on the mudflats, and there were six of us, no, seven, six of us......"

Chen Guan listened quietly, without interrupting the old fisherman's upside down.

"We all ran down to the sea to see the goods that we didn't see in ordinary times. At that time, I saw a big hole under the Mantou Mountain in the distance, and I looked at the black hole inside. The six people I was with also saw it. Unfortunately, none of us knew that the sudden retreat of the sea at that time would be a catastrophe. Not long after, we heard someone shouting at us in the distance, it was my two uncles, I was very obedient at the time, I heard them shouting, I walked to the shore with the dog, and the other children ignored it and continued to pick up things. They are all poor families, and those seafood can be exchanged for a lot of money. We had not been walking long before we heard a rumbling sound coming out of the sea. I saw a big wave higher than the hill in the distance, and it pressed over from a distance. ”

The old fisherman pointed to the hill in the distance and said, "My uncle ran over and picked me up and the dog and ran back, and the children behind also began to run to the shore, but the waves came faster. In the blink of an eye, it was at our feet. Uncle Clan and I were overturned by the waves and rushed into the distance, thanks to Uncle Clan hugging the big tree. I survived, and they never saw them again. The dragon king was furious, and they were all taken away by the dragon king. ”

The corners of the old fisherman's eyes were a little moist, and he was thinking about the past in a daze.

"Is that hole huge?" Chen Guan asked suddenly.

"At that time, I could see it clearly from a distance, and it must not be small. According to the old people in the village, legend has it that when the Eight Immortals crossed the sea, the Dragon Prince, who was beaten by the Eight Immortals, finally hid in a crack in the stone, leaving a black hole there. Dragons can hide in it, and that hole must not be small. The old man spoke with confidence.

After chatting with the old fisherman for a long time, Chen Guan left. But when he was gone, the old fisherman told him a few more words: "Young man, don't go there, for there is a sturdy young man from the nearby village who goes in and never comes out." The old people said that there was a dragon living in it, and if you entered, you would be eaten by him. ”

Chen Guan smiled and replied, "Don't worry, I won't go!" ”

The next day, Chen Guan led six people on a fishing boat to the vicinity of the Mantou Mountain mentioned by the old man and carried out a detailed survey.

"It's already OK there?" After Meng Xiang heard Rat Er's report to him, he was also very curious in his heart. In later generations, he heard many examples of entire mountains hollowed out as bases, but today he hears of natural caves.

"It is still feasible to use it for a temporary submarine base. The average depth of the surrounding water is 14.43 meters, and the shallowest point is 9.6 meters. The entrance to the cave is two meters below sea level, even at low tide, and according to hydrological observations over the years, it will not be exposed even if it encounters the lowest low tide of the year. At this time, Chen Guan was already sitting in front of Meng Xiang and reported to him carefully.

"The entrance of the cave is approximately oval, about 13.9 meters high, about 9.8 meters wide at the narrowest point, and the thickness of the surrounding stone walls is about ** meters, which can be artificially expanded. The cave is 261 meters long and has two cave halls. The largest cave hall on the outside is oval-shaped, more than 40 meters high, half of which is exposed to the water, and the width is about 53 meters at the widest point. The cave hall inside stretched upwards, less than a third of the way through the water. In general, it is suitable for use as a submarine base. The Nie Zheng drove into it and tried it, and it shouldn't be a problem to accommodate ten Assassin-class submarines inside. From Penglai, you can attack at any time and control the area of the Miaodao Islands. Chen Guan couldn't help but wave his hand excitedly.

Meng Xiang was also very happy, since the submarine was founded, the submarine has not had a safe place to stay, and it has been temporarily docked at some temporary replenishment points. You can't use a buoyancy device to transport it back and forth to the shipyard in Giethoorn every time, right? The submarine base that has been exploring finally has an eyebrow, which gives the submarine force a cornerstone for development and growth. It's not very big, but it's enough for the current Vanguard.

"Then hurry up, quickly set it up, and wait for Operation 302 to let the submarine hide in it and rest." Meng Xiang instructed. The operation No. 302 he was talking about was the operation of attacking the devil's troop carrier. After initially deciphering the devil's code, Meng Xiang imitated some practices in later generations and instructed the vanguard army to use code names for the class plans and units to reduce the possibility of leakage.

Soviet Russia was compiled in this way, and a lot of information would not be revealed in the telegram, so that even if the code was deciphered, there was no specific relevant information, and there was only one way to stare at the codename.

At about 5 o'clock in the morning on March 6, the devil's troop carrier began to set off again after repairing from Weihai. The sky was still dark, and the cold wind left over from winter seemed to have not dissipated, and bursts of wind were sticking to the sea level and burrowing into people's arms.

Higashino Ryohei put down his binoculars, rubbed his fingers, shrugged his shoulders, and shrunk his neck, half an hour of observation made him a little frozen.

At night, you can't see anything on the sea, but the stars in the sky are shining, just like what you see at home. He thought of his two children at home.

"The little one is almost three years old, right? I haven't seen each other for more than a year, and I don't know what it's like. When I earned enough money in China, I bought them Western clothes when I went back. He touched the pair of gold earrings in his personal pocket, and when he was in Weihai, he saw a woman with good earrings on her ears, and he also followed the example of others to step forward and pull one off. Even the man from the woman came, but he just nodded and gave another earring. This is just a pair of gold earrings, I heard that Fujino and they used explosives to blow up the vault directly in Nanjing and move things out. The houses there are just going in and rummaging through the valuables. If the 16th Division hadn't left too early, I was afraid that they would have gained even more. There are still a lot of places that have not been rummaged. Some of the people in China are very rich, and there are many good things in their capital, but they don't know how to use them. With so much money to buy machines and build weapons, isn't that how strong you can be quickly?

Thinking of the silver earrings that his wife had donated to build a big battleship, he touched the gold earrings in his pocket again and smiled slightly. He did not observe the foam as the periscope rose in the distance.

According to information from Weihai intelligence officers, the submarine quickly tracked the troop transport fleet.

Long Si was observing the fleet in the distance from the Jing Ke at this time.

The three merchant ships lined up in a column, with a distance of about 500 meters between the front and the back. In the front is about 6,000 tons of Nagatsuru Maru, in the middle is the Changshin Horse, and in the back is the Miyashin Maru. More than 400 meters on each of them, they were escorted by a Muyue-class destroyer.

"The Muyue-class destroyer can reach a speed of 37 knots, and has four single-mount three-year 120-mm L/45 guns, a triple 12-year 610-mm torpedo, and two depth charge projectors. The threat is great. So we had to concentrate on attacking these two destroyers at the beginning. Because we are raiding, it is possible to use two submarines against one destroyer. If you are caught off guard, you may have a good result. At that time, Jing Ke and Yao Li attacked the destroyer on the left in a group, and Zhuzhu and Nie Zheng attacked the destroyer on the right. After the attack, no matter what the situation of the other group is, the Nagatsuru at the front must be dealt with first, and most of the soldiers of the 38th Wing are on that ship. After the battle of Nagatsuru Maru, they continued to jointly support another group, followed by Miyashin Maru, who shipped the remaining soldiers and some small arms, and finally Changxin, who shipped equipment. The pale-faced Navy Lieutenant Staff Officer Lu Xingzhou explained the attack plan again.

"Are you alright? You're already familiar with these plans, so why don't you take a break! Chen Guan looked at Lu Xingzhou, who was a little weak, and said with concern.

At the strong request of Chen Guan and Lu Xingzhou, both of them boarded the Jing Ke. But the environment of the submarine made Lu Xingzhou a little unbearable, and he vomited three times in a row. He didn't board the ship many times, and he was still a little seasick, but he was influenced by his father since he was a child, and he still wore the navy clothes without changing his heart. After many failures, he completely lost the possibility of becoming a captain on the ship, and for the sake of his father's face, he stayed in the logistics department of the Central Navy. Although he is full of oil and water, he has always longed to embrace the ocean.

As the Vanguard recruited naval talent, he gladly volunteered to join the Vanguard Navy. But seasickness is getting worse on submarines. But he still insisted on refusing to rest, according to his words, he wanted to see the devil's troop carrier sink with his own eyes.

After explaining the plan to the commanders of the submarines once again, the four Assassins began to lurk towards their targets.

The devil's fleet was still slowly sailing, and due to the slowness of the troop carriers and the influence of the night, the moon number also dropped to a speed of twelve knots. Ryohei Higashino was still looking around with a telescope, but the sky had not yet shining, and what he saw was still a dark sea water, and only the occasional rolling waves brought up patches of white light.

"Maintain the depth, advance three!" This time, Long Si was still personally commanding on the Jing Ke.

"Right hand rudder 10 degrees."

"Left rudder 5 degrees, 2 meters up."

"Keep course! Float 70 centimeters and move forward one. ”

"The target has been locked!" Zhong Shuqian reported in time.

Almost at the same time, a message came from the side of the ship, and the Ruyue had already locked on the left side of the fleet's course.

In the face of the threat of destroyers, submarines did not dare to get too close, but the draft of the Muyue-class destroyers was very shallow, only 3 meters, so long-range attacks could easily lead to increased mistakes.

"Three degrees on the right rudder, one on the front." Ryusi had already stood in front of the periscope, constantly calculating the distance change and attack angle during the operation of the two.

"1000 meters from the target!"

"Continue to float 50 centimeters!" Ryusi hesitated for a moment, but then ordered. Although torpedoes can be attacked at a depth of more than ten meters, the lower the accuracy, the lower the accuracy. The best position to attack should be to come up and attack. Meng Xiang explained that Long Si's first order was to attack, so Long Si chose to float as much as possible.

"Torpedo Tube No. 1 ready!"

"Torpedo Tube No. 2 ready!"

"800 meters from the target." In order to hit with one blow, the submarine took advantage of the darkness to get closer.

"The target has been confirmed!"

"The target has been confirmed! Attack ready! ”

"Identify the target and attack on your own!" Ryusi commanded as he stared at the periscope.

There was silence in the Jing Ke's cabin, and the crew were all in their respective positions waiting for Ryusi's orders. Chen Guan's palms holding the handrail next to him were already full of sweat, and Lu Xingzhou's sweaty face was even whiter, he couldn't feel that dizziness at this time, he just felt his heart pounding and wanted to jump out......

Long Si was silent for a while, and then said decisively: "Release!" At the same time, a white waterline was drawn on the side of the number.

"Hold your posts and prepare for a second attack!" Ryusi's eyes did not leave the periscope, staring at the torpedo's white line without blinking, and it continued to stretch towards the Ruyue. After the submarine attack fleet, it is generally an emergency dive to avoid the attack of surface ships, but at this time, there are two threatening ships of the devil, and each of them is being targeted, although the threat still exists, but continuing to attack is the best choice.

"That's ...... Torpedo! Without a telescope, Higashino also saw two white lines extending from the front right side of the ship, and couldn't help but hurriedly press the alarm bell.

"Enemy attack, there are torpedoes!" He shouted loudly into the communicator, and couldn't help but regret in his heart that he was negligent for a moment, didn't notice, and even let the torpedo attack on his side.

In his hurry, he took the telescope and carefully looked at the other end of one of the white lines, and in the faint light of the sky, he saw a swarthy figure less than a thousand meters away. There is a figure of the same in front.

"There are submarines!" Higashino's body tilted to the side all of a sudden.

The Ruyue began to turn sharply to the left in an attempt to avoid the torpedo. However, before the two submarines attacked, their respective positions had been determined, one in front of the other, and different angles of attack had blocked its evasion.

"Boom!" With a loud bang, a large hole was opened in the left waterline of the 553-mm torpedo that was about to leave, and the explosion made the front end of the Ruyue jump sharply. Higashino was thrown aside at once, but fortunately he was not thrown out thanks to a protective belt that was tied to him. This was followed by a loud bang, and another torpedo was hit at the position of the thruster of the Moon.

A "squeak" sound of steel being twisted came from under the ship. For example, after the moon horn shook to the right, it shook and then tilted to the left. A large amount of seawater poured into the two holes, and the torpedo in the back broke the power system of the moon. But even if it is intact, the water pumped out cannot match the speed of the influx of seawater.

"Boom" came again, and the Shui Wuyue on the other side was also swept into the stern by a torpedo. Zhuan Zhu and Nie Zheng participated in the actual battle for the first time, and they were inevitably a little unskilled, and they only hit one shot. When he was first considering grouping, Chen Guan put forward the suggestion of concentrating on sinking one ship first, so it was still a group of Jing Ke who were more proficient and wanted to leave the number.

Although only one shot was hit, the 553-mm torpedo was not so tasty, and the explosion in the stern, although it did not hit the point directly, the keel was already damaged, leaving it directly there. The sailors hurried to plug the leak, but they could only slow down the sinking speed.

Ruyue only struggled for one or two times, and it had already sunk for more than half of it, and the devil's sailors were looking for life-saving products to dive into the water, desperately swimming far away. At this time, the sea water is so low that if you don't get help in time, it will be over in a few minutes.

In less than two minutes, the Ruyue had sunk to the bottom of the sea. Ryohei Higashino stood on the watchtower with gold earrings in his hands, and sank into the icy water. If it hadn't been for this attack, perhaps in a few years, Ruyue would have been smothered by a 12.7 heavy machine gun bullet detonating a depth charge, at least a more dignified sinking than in the original history.

"Boom!" On the other side, Shui Wuyue was attacked by another torpedo from Nie Zheng, who had made up for his merits, this time Shui Wuyue, who had been paralyzed, was unable to dodge, and was directly hit, and after a bounce, Shui Wuyue stood up directly and quickly sank into the water backwards. The shell that urgently counterattacked on it landed behind the Zhuanzhu, causing everyone to break out in a cold sweat.

The Mizuki did not escape the fate of being sunk by submarines, but one was an American submarine and the other was a submarine of the German Vanguard.
