U-38 travels underwater at a speed of four knots, and every half hour, Lin turns on active sonar, but the result is similar each time: the echoes are chaotic, as if there are countless ships on the sea. The pen "Fun" Pavilion www.biquge.info reluctantly turned off the monitor and started it again after an hour, but the situation changed again: there was no echo at all. His face turned pale instantly, and he whispered to Lu Ruping: "It's over, the monitor is broken." ”

Lu Ruping has been watching his operation, this situation is also unprecedented, he snatched the headset of passive sonar and listened to it, and said with a sigh of relief: "There is no movement on the sea." ”

"No movement?" Lin Lianfan has been paying attention to active sonar for the past few hours, and passive sonar has not listened carefully.

"Yes. There is no propeller sound, you listen to it yourself. Lu Ruping took off the headset of the passive sonar and handed it to Lin Lianfan, and then said to himself: "Could it be that all the Japanese have landed?" Impossible. ”

"How could the Japanese have landed all of them in such a short time?" The speculation in the sonar room was reported to the captain's room, and Li Kongrong shook his head vigorously without listening. "They must have turned off the engine to lure us up."

"Is it possible for the Japanese army to land in a different place?" Su Jinghu was sitting in the captain's room reading a novel when he heard this.

"No way!" Li Kongrong shook his head again. "There will only be two scenarios for the Japanese army to fight, first, even if all of them are dead, they must execute everything as planned. Rigidity and inflexibility are their stubborn diseases; Second, a more radical plan was adopted that was initially thwarted by the staff headquarters or superiors, but in the end it was overfulfilled at the instigation of the junior officers' staff officers. Landing in Qinzhou is the most convenient way to occupy Nanning, it is impossible for them to go around to Beihai to land, it must be here. ”

"Then why is there no movement, and no sound can be heard?" Although everyone present did not know whether this was true or not, they did not doubt it in their preconceived ideas.

"Now ......" Li Kongrong looked at his watch, and it was almost half past eleven. It stands to reason that the Japanese army's demining has been completed, and the landing should be completed after the demining is over, and the landing, whether it is a large or small boat, has an engine propeller, and there will be a sound, is it ......

"Release the antenna immediately and see if we can contact the Army." Li Kongrong said. After he finished ordering, he called Lin Lianfan and Liu Yongren over, "Where did you last hear the propeller?" ”

Lin Lianfan has been operating active sonar, passive sonar has not paid attention, and the active sonar range is no more than two kilometers, and he has forgotten where the last propeller is, fortunately, Liu Yongren has been paying attention to the position of the enemy ship, he said: "According to the final report, the enemy ship should be in the position of zero four or five now." ”

"Then turn around and head towards zero four five." Li Kongrong glanced at Su Jinghu and asked, "Is the electricity enough?" ”

"I can stay up until the night." Su Jinghu replied, he said that he was afraid that Li Kongrong would have no fear, and then said: "It is a little bit to save a little, this is a bay after all." ”

"What are you afraid of, it's a big deal to retreat into Qinzhou Bay." Li Kongrong smiled, this was his last plan - the depth of the main channel in Qinzhou Bay was 15 meters at its lowest, and the depth of the mine must be more than two meters because it wants to prevent the large and small boats with extremely shallow draft. The U-38 boat is 9.4 meters high, and even if it is two meters from the bottom of the sea, it is still 1.6 meters from the mines above. There is really no way, the minefield in Qinzhou Bay is the bomb haven of the U-38.

Li Kongrong mentioned his backup plan with a smile, and several people moved their butts - where it is not good to go, but they run into the mine pile, in case the mine fuse fails, the submarine will be miserable. Everyone did not speak, except for the two electric motors, which faithfully pushed the U-38 forward slowly, and the towed antenna on the rear deck of the submarine was laid out little by little under the action of the motors. In order to conceal it, the end of the antenna is designed as a green clump of aquatic plants, and the salt cubes placed in the aquatic weeds are slowly melting, and after half an hour, when the submarine is two nautical miles away, the aquatic plants that have lost their salt masses will surface and send and receive all information in the current.

Half an hour is not difficult to wait, but in Nanning City, Du Yuming has been waiting for more than six hours.

"Why hasn't there been any news yet?" He looked at Hou Teng, "Could it be that Brother Hansheng's newspaper receiver is broken?" "When Berlin said goodbye, now it is so close, no wonder Du Yuming will call back excitedly as soon as he receives Li Kongrong's message, but his message is too long, and when the power is generated, the U-38 has already dived to the bottom of the sea, and the unwilling Du Yuming has been asking the operator to call, but there is no response.

"Junzuo, I think Brother Hansheng has dived to the bottom of the sea, and it's strange to hear the call." Hou Teng was also happy when he talked about Li Kongrong, but everyone was at sea and Nanning at the same time, and they couldn't meet more than 100 kilometers apart.

"Call a little longer." Du Yuming also felt that what Hou Teng said made sense, but he still didn't give up. Fortunately, it was his undying will, and half an hour later, Liu Nongjun, the commander of the communications battalion, made a phone call and said that the U-38 had finally been called. Du Yuming was originally sitting, but after hearing the news, he jumped up, but fortunately, the military telephone line was long and the line was not broken. "Since communication is inconvenient, let's make a long story short, just tell him that I, Du Yuming, is in Nanning, and send it out immediately! Send it now! Du Yuming was worried that the communication would be cut off again, so he immediately changed his mind.

"Sir, there's a secret call from an unknown radio station, and the password is unknown." On the U-38, as soon as the radio station was turned on, it received a message from Nanning, but it was not a clear code, although it was also a number, but Lu Ruping knew at a glance that it was not the internal password of the navy.

"What about novels?" Li Kongrong took the secret telegram, turned his head and asked Su Jinghu.

"Novels? What fiction? Su Jinghu didn't understand why Li Kongrong asked about the novel, but fortunately, he was not slow to react, and the book of Three Heroes and Five Righteousness that he had read and read immediately took it out.

"This is the codebook." Li Kongrong handed over the Three Heroes and Five Righteousness to Lu Ruping, and then whispered a few key numbers in his ear to let him decode. "This is sent by Du Guangting of the 88th Army, and when I was in Berlin, I made an appointment with him to use this Three Heroes and Five Righteousness as a code book. Since he called, he received the clear message in the morning on time, and he was in Guangxi......"

Li Kongrong explained. The telegram was brief, and Lu Ruping quickly finished decoding, and he came over and said, "Sir, Chief Du said that he was in Nanning." ”

"Immediately, let him contact the Qinzhou front line to investigate the situation and distribution map of Japanese ships off the coast of Qinzhou Bay, to be accurate! 100,000 urgent. Li Kongrong wiped his sweat.

"Yes!" Lu Ruping agreed and went immediately, he was fully aware of the current predicament of the U-38.

"How far is the line going?" Li Kongrong turned around and asked Lin Xiangguang, this was his business.

"Three nautical miles more." Lin Xiangguang, who was in charge of laying out the line, replied.

"Three nautical miles is enough." Li Kongrong looked at Lu Ruping, who was sending a telegram in the glass window, and only hoped that the Japanese radio line finder would be more accurate and not throw depth charges on his head.

The 3MHz high-frequency radio signal was sent from the aquatic weed-like antenna three nautical miles away from the U-38, and as soon as the first word was spoken, the two radio direction finders on the Chokai jumped out of the detection signal, and the Japanese sergeant guarding the side reported loudly: "The radio waves of the submarine in China have been discovered, and the radio waves of the submarine in China have been discovered......

"Sideways positioning right now!" Rokuro Sato, the official of the main electric power, sighed in his heart, and stood up in good spirits, hoping to find the radio position to sink the submarine in China. Although the U-38 was too close, the Chokai was more than 200 meters long, and the two direction finders finally determined the approximate location of the radio waves.

"Are you sure it's a submarine in China?" Yamaguchi Tawen, who received the report for the second time, looked at the target area again, and it was calm.

"Yes, Your Excellency, this is a high-frequency short-wave radio station commonly used by the Navy of the Independent Nation." Rokuro Sano, the official of Zhengden, nodded in great affirmation.

"But nothing has been found in the dinghy on the sea...... "Captain Kouda Goro was puzzled, this was the second time Sanno had reported, he had ordered the dinghy on the sea to search, but nothing was found.

"Your Excellency, it is very likely that the country has a method of underwater reporting, and now it is the second time it has sent a report." Rokuro Sano's point of view was insisted on, he was sure that there was nothing wrong with the direction finder, and the submarine in Shina was in that direction.

"Well, the independent country is a big country in science and technology, maybe they can do it under the water." Yamaguchi interrupted the argument between Koyu and Sano, and he said, "Inform the 5th Destroyer Team to go searching, maybe depth charges can blow it up." ”

"Hey!" Since Yamaguchi decided to search, Gu Uda Goro had to agree, his voice was extremely loud, and it seemed that he would not be able to express his decisiveness if he did not do so. At this time, all ships on the sea, including the destroyer cruiser, were suspended, the purpose of which was naturally to lure the submarine to the surface, and now that the whereabouts had been discovered by radio direction finders, the tracks should no longer be concealed.

The Torikai sent the order to the flagship of the 5th Destroyer Group, Asakaze, and soon, under the banner of 'Follow Me', the other three destroyers launched a search for the target area. As soon as the propeller turned on the sea, the U-38 on the bottom of the sea immediately noticed that while Lin Lianfan recorded the position of the enemy ship, Lu Ruping immediately rushed to the captain's room to report: "Sir, the enemy ship has been discovered." ”

Li Kongrong and several officers were eating, and he didn't have time to get up, so he only stretched out his hand and said, "Quick, turn on the active sonar!" ”

Although the passive sonar was used at this time, the active sonar display had been standby, and when Lu Ruping did not return to the listening room, Lin Lianfan had already turned on the active sonar, and when he saw the familiar echo, he finally breathed a sigh of relief. At the same time, he also roughly guessed the reason why there was no echo just now - the active sonar beam is narrow, and the detection distance is less than two kilometers, and there are many clutter before because the beam angle is high, and the sea surface is within two kilometers; The lack of echo is due to the fact that the beam angle is low and there are no obstacles within the detection distance.

In a flash, Lin Lianfan thought so, but he didn't think about why there was clutter on the sea surface within the detection distance, and there was no reaction when the sea surface was not within the detection distance. If he really thought about it, he could easily come up with the answer: there were so many motionless boats on the surface of the sea that they made the sonar appear clutter; After adjusting the beam emission angle, the boat with a very shallow draft cannot be detected, and there is nothing in the detection range, and the display naturally does not react.

In the excitement of re-detecting the enemy ship, Lin Lianfan immediately recorded the position and speed of the enemy ship, and when Li Kongrong rushed to the control cabin, he reported very fluently: "Report to the chief: The enemy ship is at a distance of 1,600 meters, the azimuth is 260, the course is 175, and the speed is 24 knots, please ...... immediately."

The enemy ship was almost parallel to the U-38, but in the opposite direction, it was heading towards the direction of the antenna, Li Kongrong understood that the opportunity was rare, and Lin Lianfan said before he finished speaking: "The combat position of the whole boat!" The right rudder is full, and the course is zero ninety. The No. 2 torpedo tube was ready for ......, the enemy ship was at a distance of 1,600, the azimuth was 260, the course was 175, the speed was 24 knots..., the torpedo was set at a depth of 3 meters, and the speed was 45 knots......"

Under his order, the submarine turned on the No. 2 torpedo tube while turning, and the sound of the propeller overhead was faint at first, and then it was deafening - the speed of twenty-four knots was equal to 740 meters per minute, even if the submarine turned to the active sonar detection range doubled, it would only take 4 minutes and 50 seconds for the enemy ship to cross this distance, and the current situation is that the enemy ship is 800 meters away from the submarine, and it only passes through this circular side with a diameter of 3,600 meters, and the distance that can be irradiated by the active sonar is only a short 1,800 meters, according to the calculation, which disappears from the monitor in two minutes and twenty seconds. Li Kongrong naturally would not miss this unmissable opportunity, and as soon as the deafening sound of the propeller passed the peak, he coldly ordered: "The No. 2 torpedo is fired!" ”

"Torpedo No. 2 launched!" The order of the bow torpedo compartment was equally cold, and as soon as Chang Xiangqi's words fell, the Mark 8 torpedo came out of control.

The waves on the sea were still turbulent, but the rain had stopped, and the torpedo not only appeared out of thin air thirty meters from the bottom of the sea, but also spewed out countless bubbles, which were naturally discovered by the boat on the sea, and one of the sailors on the boat was so frightened that he almost fell into the water, but fortunately he froze his body, and then shouted at the destroyer eight hundred meters away: "Torpedo!" There are torpedoes! ”

The sailors saw bubbles instead of thunder tracks, and the torpedo that was advancing at a high speed of 45 knots rushed out of the bottom of the sea for more than 50 meters before gradually rising to the position of fixed depth under the action of the balance cabin, and at this time the torpedo trail appeared on the sea surface, and the lookout of the Chunfeng who saw the thunder trail sounded the alarm bell in panic and shouted with all his might: "The port side has found a torpedo!" A torpedo was found on the port side ......"

At a distance of 800 meters, a torpedo at a distance of 45 knots takes only 34.5 seconds, and the reaction of a man may not be slow, but the reaction of a ship is much more than that of a full man. Under the cold sweat of the captain Tsunoda Chiyoyoshi Shaosa, the Spring Breeze was avoiding the torpedo with the right rudder, but the distance was too close, and in the middle of the half-turn, the torpedo hit the port side of the Spring Breeze, and the 340 kilograms of TNT explosives on the head of the thunder were instantly detonated. After an incomparably shocking loud bang, the bulkhead on the left rear side of the Chunfeng was blown up, and nearly 100 tons of seawater poured in, and in less than two minutes, the kamikaze-class destroyer with a displacement of only 1,200 tons was bowed high, but before the crew escaped from the cabin and jumped into the water, it broke into two pieces under the action of gravity, and then quickly sank to the bottom of the sea.

One thunder for one ship! Although there is no declaration, the action has been declared. Witnessing the sinking of the Chunfeng, every Japanese was stunned: this was a massacre! The massacre of the Imperial Japanese Army!

"Find it! Be sure to find it!! The furious Yamaguchi no longer showed any appreciation, and his command knife was sheathed with a bang, and his face was extremely hideous. (To be continued.) )
