Half an hour had passed, and it was already two o'clock in the afternoon, and Yasuwa Hoshino and Ishihima Koyama were still anxiously waiting for the message from the I-5 submarine, and Yasuwa Hoshino asked the radio operator, "Did you receive the signal?" ”

The operator shook his head silently and said, "No signal from the I-5 submarine was received. ”

Hoshino said, "Could it be that our communication system is malfunctioning? ”

The operator shook his head and said, "No, our communication system is very good, and the self-test circuit has not found any faults." ”

Hoshino Yasuwa said, "Could it be that the self-detection system is malfunctioning?" ”

Without waiting for the operator to speak, Koyama Ishiji said on the side: "Hoshino-kun, you are too anxious, don't worry, let's wait patiently." ”

Hoshino Yasuwa said, "Koyama-kun, can I not be in a hurry? You see, it's already two o'clock in the afternoon, and in half an hour we'll be retreating. ”

Koyama Ishiji said, "Hoshino-kun, there is still half an hour, and perhaps the most critical turning point will come in the last half hour. ”

Hoshino Yasuwa let out a long sigh and said, "I hope so." Koyama-kun, could it be that the I-5 submarine has already sent a message, and we have not received it. ”

Xiaoshan Shiji shook his head and said: "No, according to our experiments, the message sent by the communication system on the I-5 submarine will definitely be received by us, and the water quality here is more suitable for electromagnetic wave propagation, Hoshino-kun, you can relax." ”

Hoshino Yasuwa nodded and said, "Koyama-kun, can't our sonar make a sound to communicate?" ”

Xiaoshan Shiji said: "In principle, it is possible, but there are some key techniques that have not broken through, so they are not used on our batch of submarines, and the next batch of submarines should have a sonar system that actively emits sound waves." ”

Hoshino Yasuwa said "um" and stopped talking, at this time the time had come to half past two, and he still hadn't received the news that Lin Yuan's warship was coming, Hoshino Yasuwa said helplessly: "It seems that there are no warships coming, our plan has failed, and now there is only a return." ”

Xiaoshan Shiji nodded expressionlessly, after all, the failure of the plan is not a new thing, Hoshino Yasuwa ordered the chief engineer at this time: "Increase the power of the motor to eighty percent, float to a depth of forty meters, and the speed is eight knots, target Wonsan Port, and return." ”

As soon as the order was given, everyone took action and sailed towards Wonsan Port according to the predetermined route, at this time they didn't know about Ichiro Abe, and at half past four in the afternoon, Hoshino Yasuwa's submarine team sailed into the range of the aft towed array sonar of the Fire Phoenix and Kirin ships.

Although the Japanese submarine is behind the Huofeng and Kirin, and the propeller does not directly face the sonar, when the submarine is working, the sound source is not only the propeller, the vibration of the main engine and auxiliary engine in the submarine will make a huge sound when it is working, and the submarine will push away the sea water when it is moving, forming a wave Lang, which is also the source of noise, so the sound of the Japanese submarine was quickly heard by the Huofeng ship.

The sonar chief on the Huofeng ship immediately reported to Yu Feng after hearing the sound signal of the Japanese submarine: "Captain, the towed array sonar has found the target, the target is behind our ship, and the details are still being detected!" ”

When Yu Feng heard this, his heart moved, and he thought: "The signal of the Japanese submarine is coming from behind us, not from the front, aren't we chasing the Japanese submarine?" How did you run in front of the Japanese submarine? Yu Feng said to the chief of staff beside him while thinking: "How can we run in front of the Japanese submarine?" ”

The chief of staff thought for a moment and said, "This may be the trick used by Ichiro Abe. ”

Yu Feng asked, "What trickery?" ”

"He deliberately told us the wrong course and the wrong speed, so that our warships rushed to the front of their submarines, and the back of the warships was the noisiest place, so the sonar on their submarines could easily detect us, and our sonar could not easily detect them," the chief of staff said. ”

Yu Feng smiled and said: "So that's the case, it's a pity, they don't know what to do, we have a towed array sonar, and there is no dead end in the detection of the stern." ”

The chief of staff said, "Should we call that Ichiro Abe and expose his tricks on the spot." ”

Yu Feng said: "Don't rush to conclusions, maybe this Abe Ichiro really wants to surrender, the information he gave us is true, but there was an accident on the way of the Japanese submarine, so he slowed down and ran behind us instead, so let's call that Abe Ichiro and let him see our battle, whether he is lying to us at a glance." ”

The chief of staff asked, "How can you see this?" ”

Yu Feng smiled: "If he really helped us, he should be happy to see us sink the Japanese submarine, if he is using conspiracy to deceive us, then he will definitely be sad, right?" ”

The chief of staff laughed loudly: "If the captain still has a way, I will let someone call him." It didn't take long for Ichiro Abe to come to the command room, and Ichiro Abe's heart was also up and down, thinking: "Can our submarine find the warship of Lin Yuan's troops?" What if I can't find it? Will the submarine warship meet them? ”

Ichiro Abe was thinking about it, when Yu Feng smiled and said, "Mr. Abe, thank you so much. ”

Abe Ichiro was at a loss for a while, and hurriedly asked, "Thank you?" Thanks to me for what? ”

Yu Feng said: "Of course, thank you for telling us the route of the submarine team!" Now we've found them! ”

When Ichiro Abe heard this, he felt a "boom" in his head, as if there was a thunderbolt, and he thought, "They actually found us?" Could it be that our submarine squadron did not retreat according to the predetermined speed in the plan, but instead walked in front of Lin Yuan's warship? ”

Ichiro Abe desperately squeezed out a smile and said, "How did you find them?" Where are they? ”

Yu Feng pointed to the back of the warship with his hand and said, "It's right behind our warship." ”

Ichiro Abe's eyes widened when he heard this, and he said, "Behind the warship? So you can all find them? Aren't there propellers behind warships? Wouldn't the noise from the propellers interfere with the sonar of the warship? ”

Yu Feng nodded with a smile and said, "Of course it will, but we used a special method to solve this problem!" ”

When Ichiro Abe heard this, he only felt that his eyes were dark, and his body was about to fall, and the marines next to him hurriedly held him up, Yu Feng saw that Ichiro Abe was like this, so he smiled secretly in his heart: "It seems that he is really using conspiracy, he didn't expect that we used towed array sonar, right?" He's really shooting himself in the foot! ”

Yu Feng said to his subordinates: "Go and call the Japanese interpreter over, and move a chair for Mr. Abe, since Mr. Abe has helped us so much, let's ask Mr. Abe to take a good look at our battle." ”
