Yu Feng asked, "What is your scheduled retreat time?" ”

When Ichiro Abe heard this question, he screamed in his heart, and thought to himself, "This question seems to be ordinary, but it has a murderous motive!" If I answer the slightest carelessly, my trick will be revealed, first of all, I speak of retreating sooner than their reconnaissance power arrives, and if I say it late, they will be suspicious. ”

"I was caught on the warship at about ten o'clock in the morning, and their reconnaissance force must have been dispatched later than ten o'clock, so I said that ten o'clock is the safest, but I can't say ten o'clock, if I say ten o'clock, it means that the ambushed submarine will retreat without waiting for my submarine to return, which is obviously impossible."

"Last time, I said that the submarine ambush circle is sixty kilometers away from here, and according to the maximum underwater speed of our submarine twelve knots, sixty kilometers will take nearly three hours, that is: my submarine will not arrive at the ambush circle until one o'clock in the afternoon, so the retreat time must be later than one o'clock in the afternoon!"

"But it's only 1:15 now, and they must have detected that there are no submarines in that area, so wouldn't I be exposed to anything! Moreover, looking at the appearance of this captain, he is by no means an amateur in submarine warfare, and he must understand that it is difficult to maintain the maximum speed of a submarine for three hours. ”

Abe Ichiro trembled a little when he thought of this, so he had to say, "Our submarine will retreat at twelve o'clock at noon. ”

Yu Feng frowned and said, "Twelve o'clock at noon? Then your submarine hasn't returned to the ambush circle. ”

Abe Ichiro smiled and said, "Mr. Captain, why didn't our submarine return to the ambush circle?" ”

Yu Feng said: "I have seen the performance data of your submarine, and the maximum underwater speed is only 12 knots, how can 12 knots cover 60 kilometers in two hours?" And from here to where you said, the direction of the current is opposite to the course of the submarine, and you can't go so fast. ”

Ichiro Abe thought to himself, "It's here! The captain did think about it! Ichiro Abe froze and said, "Mr. Commander, the maximum speed of this submarine of mine is twenty-one knots, and the usual speed under water is eighteen knots, why can't we cover sixty kilometers in two hours?"

After Abe Ichiro finished speaking, he smiled secretly in his heart: "I just said that my submarine has a speed of eighteen knots, anyway, my submarine has sunk, and there is no proof of death!" ”

Yu Feng's brows furrowed slightly, and he said, "The maximum speed of your submarine is twenty-one knots?" So fast? ”

Ichiro Abe said calmly: "Of course, my submarine has been specially improved, so it can be so fast. ”

Yu Feng asked suspiciously, "Special improvements?" What special improvements? ”

Ichiro Abe said: "I don't know much about the arts, but I still know some improvements, such as the improvement of batteries, on other submarines, lead-zinc batteries are used, and on my submarines, silver-zinc batteries are used, you should know the strength of the silver-zinc batteries, right?" ”

Of course, Yu Feng knows the strength of the silver-zinc battery, the storage capacity and functional power of this battery are much higher than the lead-zinc battery, in modern weapons and equipment, the silver-zinc battery is the first choice for all kinds of weapons and equipment batteries, and the batteries used in spacecraft, missiles and torpedoes are basically this kind of battery, but no country dares to have this kind of battery on the submarine, the reason is very simple: too expensive! If a silver-zinc battery were to be used on a submarine, then the sterling silver used would be as high as twenty tons! No country dares to burn money like this.

After listening to Abe Ichiro's words, Yu Feng thought to himself: "The little devil is really crazy, he actually used so much silver as a battery, so it is not surprising that their submarine can run at such a high speed." Yu Feng then said, "Okay, tell me the retreat route of your fleet." ”

Ichiro Abe felt a burst of ecstasy in his heart, and thought to himself, "Great, he believes it!" So Ichiro Abe said, "Please let me mark the route for you on the chart." ”

Yu Feng said: "Okay, come with me." Yu Feng took Ichiro Abe to the electronic chart again, and Yu Feng pointed to the electronic chart and said, "Please mark the retreat route." ”

Ichiro Abe nodded, took the electronic pen handed over by Yu Feng, and thought to himself: "The route I drew must let this warship chase ahead of us!" Abe Ichiro pondered in his heart for a while, took the electronic pen and drew it on the electronic chart, and then said: "This is the approximate direction, no matter how accurate I am, I can't hand it over to you, you also know that I am the captain of the ship, and the captain is responsible for such things as the navigation route." ”

Yu Feng nodded and said, "Okay, I know the truth." After Yu Feng finished speaking, he asked Ichiro Abe to take him down, and then the chief of staff on the side came over and said, "Captain, do we really have to believe that guy's words?" ”

Yu Feng said: "Of course you have to believe it, I don't think he is lying to me." ”

The chief of staff said, "But I always feel that this guy is using a scheme!" ”

Yu Feng shook his head and said, "What kind of conspiracy do you think he can use?" ”

The chief of staff shook his head lightly and said, "I can't think of it either." ”

Yu Feng smiled: "You don't have to worry, we won't have anything, although this matter has a certain risk, but if what he said is true, we may annihilate Japan's submarine force in one fell swoop, and the benefits are much greater than the risks." ”

The chief of staff nodded and said no more, Yu Feng continued: "In order to protect our tail from being attacked, immediately cast a towed array sonar; The sonar detection force on our side is also relatively weak, and two unmanned underwater vehicles have been released to probe the sea area on both sides of our ship. ”

The chief of staff said: "Actually, it is enough for us to put down one submarine, and we and the Kirin can form a two-ship formation to cover each other's side." ”

Yu Feng said: "Okay, let's do it." The chief of staff then went to give the order, and soon the Huofeng ship and the Kirin ship put the towed array sonar they carried into the water, and the towing cable of this towed array sonar is more than 500 meters long, and the sonar can be placed far behind the warship, so that the sound signal from the target behind them can be heard, and the signal is transmitted to the command center of the warship through the optical fiber in the towing cable.

After the two warships put down the towed array sonar, they respectively put an unmanned underwater vehicle into the water, which itself has a sonar system that can detect the sound signal in the direction of the warship's sideboard.

The two warships headed in a false course and gradually came to the front of the Japanese submarine.
