Soon at noon the next day, the two warships arrived at the harbor of the fortress, and after Scarlet Moon reported to one of the officers in charge of the defenders, a group of soldiers came over and took all the half-dead pirates or unknown armed men on the deck who had been washed away by the sea, and the submarine was towed into a well-protected warehouse.

"Lina Linna, we are going to make meritorious contributions!" Scarlet Moon took Su Fan's arm and said excitedly, they are now in a conference room, just now Su Fan reported the matter in detail to a serious-looking officer, and after a guard served two cups of tea to the two, he asked the two to wait here.

"How did you make a meritorious service?" Su Fan didn't understand, towing back a submarine, although it was very fresh, but according to this shijie's jishu, it was not so difficult to make a submarine!

"Don't you know, in the previous time, there was a pirate on the southern channel of the empire, and this pirate relied on this kind of diving ship to send several first-class battleships of the empire to the bottom of the sea, but the army did not even touch a single hair of the pirate, and the empire has issued a reward, as long as you can get a diving ship of this kind, you will get a very high reward!" Scarlet Moon explained to Su Fan, Scarlet Moon often goes out to look for work or something, and she is well-informed.

"This thing...too..." For Su Fan, the submarine is a food delivery, after all, her body is an anti-submarine expert, and in her time, because of the development of anti-submarine facilities, the submarine has been driven to a dead end, only the ballistic missile nuclear submarine can survive, and other attack nuclear submarines are basically to send food to the destroyer, not the submarine can't do it, the main is too advanced detection jishu, so that the battlefield has been greatly transparent, modern warfare is jishu, jishu is on the high side, even if the commander is a pig, he can win。

But in this shijie, that's not good, in terms of force, this shijie's force is really not worse than the earth, even higher, don't look at the attack distance, but the defense is a bit too ghostly, especially the mechanic, the granite 8 anti-ship missile is also the top three on the earth in terms of power, and a hit can make Ford become a Shente, but here, all kinds of ghost animal shields or something, that is, only injuries in the mission, only ballistic missiles can kill with one hit.

The force aspect is finished.,But some jishu is bad.,It's like a submarine.,This shijie's anti-submarine is still in the state of the ear.,Use a magic array that can amplify the sound.,Transmit the underwater sound to an experienced listener (equivalent to a sonar).,And then judge the approximate location.,But can the human ear be compared with the electron? The listener can easily hear the sound of the activities of the uncivilized races underwater, because the underwater things of the uncivilized races have strange shapes, the friction is so large, and the sound can be transmitted 800 miles away when running underwater, but this kind of submarine is very quiet, and the human ear can't hear it at all.

As a result, after a few trainings, several Imperial first-class battleships that wanted to easily solve these pirates knelt down, these submarines are magic crystal engines, they can soak underwater for a long time, and after the attack, they dive directly underwater, squat him for a few hours or something, no matter how ruthless the battleship is, there is no way to take things underwater? It's okay to say that the battleship was sunk, and the empire didn't sink when it exterminated the pirates, but this group of pirates was extremely vicious, and all the crew members who abandoned the ship and escaped were cramped and skinned alive, and after being photographed with memory crystals, they were sent to the imperial military headquarters, which was a naked slap in the face.

This unknown pirate gang is very secretive, no one knows where those submarines came from, and the operation is so secretive that the Imperial fleet cannot catch it at all, and even lost a few heavy cruisers again, and these losses make the Imperial military department furious.

Just when Su Fan and Scarlet Moon were discussing what reward they could get, two officers walked in, one of them was holding a tray, and followed the other officer in, Su Fan looked at the officer standing in front, who seemed to be a lieutenant colonel, the epaulettes of the Glas Imperial Army were very complicated, and Su Fan recognized it for a long time before he could identify it.

"Miss Crimson Moon and Miss Catherine?" the lieutenant colonel asked after saluting the two.

"I'm Catherine, and she's Scarlet Moon. Su Fan nodded and said.

"Two captured a diving ship and twenty-six pirates..." The officer said a lot of nonsense, a lot of all kinds of official words, summed up in two sentences: good job, the empire has a reward, the military department of the empire awarded Su Fan and Scarlet Moon two medals, a medal named after a person, Su Fan didn't hear it clearly, but ordinary soldiers need to go to the hospital several times if they want to get this medal - don't wonder that Su Fan and they will have military merit medals, the Glass Empire is a military and political integration, and any medals are for both military and civilian purposes.

Of course, a medal alone is not enough, there is also a bonus, Su Fan is the mastermind...is the main one, there is a reward of 1 million Grass coins, Scarlet Moon is an accomplice...There is a reward of 500,000, for this, Scarlet Moon almost promised Su Fan directly in the conference room, 500,000 is a yellow-level cannon barrel!

"Two young ladies, our commander invites you two to come to his office, and wants to ask you about the situation at that time, so as to prepare for the extermination of this pirate army in the future!"

Can this be refused? Su Fan and Scarlet Moon followed behind this lieutenant colonel and came to the commander's office. The soldiers in this fortress are rotated, and they are all the ace armies of the empire, and today is the time when the two troops change guards, and it is not unusual to have so many generals.

"You're Catherine, right? How did you find out and destroy these diving boats?" After Su Fan and Scarlet Moon sat down, a middle-aged man led by him asked, some of the officers around him were amazed for a while, and then took out a pen and paper to prepare for the record, Su Fan was the only one who had destroyed and captured a diving ship, and any of her actions was experience.

"I've seen this kind of diving ship before, General, you should already know that I'm not a human being, in our race, it's customary to call this thing a submarine, a submarine is a very powerful sneak attack tool, well, in our people's cognition, this thing is a useful thing for cruisers. Su Fan began to say, the role of the cruiser is to break relations behind enemy lines, and the submarine is also to do this.

"And how did you find this thing and sink it?" asked a young officer.

"This is our unique ability, I call it sonar, and the principle is similar to that of a listener, but mine is more accurate. Su Fan said, "As for sinking, I used our clan's unique attack method, and I temporarily ..."

"I have a method that ordinary battleships and mechanics can use!" Su Fan saw the faces of those officers who changed color, she knew that those officers thought that she had fooled them, so she quickly changed her words, she believed that if she didn't say something, these officers would definitely not hesitate to use heavy punishment.

"What's the solution?"

"A special kind of bomb, after the submarine attacks, it will leave two obvious traces, but the naval gun can't hurt the submarine because of the water surface, but this weapon is a bit similar to a mine, after being thrown into the water, it will explode after reaching a certain depth, and kill and injure the submarine with explosive force...I can only come up with this method of destroying the submarine now, as for how to find it...I don't have any other way!" Su Fan said, what is the difficulty of depth charges? And the speed of the submarine is as slow as it gets, and after discovering the traces of the submarine, it would be good for the destroyer to go directly to the barrage, and there were a few of them hit anyway.

Although he did not obtain the real anti-submarine ability, Su Fan's method was barely possible, depth charges were a concept and not jishu, after a simple explanation, although those officers were not satisfied, they couldn't say anything, Su Fan and Scarlet Moon left the fortress.

"Linna, xiexie you!" Scarlet Moon stood on Su Fan's deck, and Su Fan next to him said, these credits were given to Scarlet Moon by Su Fan, and Scarlet Moon just went to play an armed parade.

"Nothing. Su Fan waved his hand, "You better fix your engine first!"

Scarlet Moon's engine has always been sad, mainly because there is no haode material, now that there is money, of course, the first time is to repair the engine, the artillery or something should be put away for the time being, after Su Fan docked, the two got off the boat and prepared to go back to the dormitory, Scarlet Moon has not slept for more than a day, and now he is sleepy, although Su Fan doesn't have to sleep, but now he has nothing to do.

"By the way, Scarlet Moon, have you found a job?" asked Su Fan.

"No, you also know that the jobs given to students around the school are basically mercenaries, but we still have to go to class, where is the time!" Scarlet Moon said very dejectedly, the merchants around the Royal University of Glas are all their own employees, who dares to hire these high-level talents in the future of the empire!

"Well...I have a good idea!" Su Fan whispered, "It's best to pull Alma and Ricko!"

"Pull them up, what are you going to do, it's not selling..."Scarlet Moon's wandering thoughts flew to Namek at once, knocking Vegeta down to Thunder.

"Sell your head, I mean sell battleship accessories!" Su Fan almost strangled Scarlet Moon to death, even if the zombie tyrannosaurus protagonist in the last book didn't fall into selling his body, right?

"Battleship accessories? You want to sell your missiles, but who used them?" Scarlet Moon said strangely, for Su Fan's missile, Scarlet Moon was salivating, and once took one and tried to put it on his body, but the problem came out, assimilation is no problem, but how to launch it after assimilation? How to aim? After the missile is installed on Scarlet Moon's body, it is an extra useless accessory, and it can't be used at all.

"I mean buy sonar!" Su Fan said, the jishu content of the sonar thing is not as high as imagined, especially the original listener is simpler, and the sonar is a complete device, not a missile that requires countless auxiliary accessories to work, Su Fan can make the sonar by hand is only the lowest level of the listener, although he can hear the sound of those submarines, but it can't affect himself! As for the copycat or something, it doesn't matter, if you listeners transform the magic array, there is no gap between the quality of the most primitive sonar.

This sonar is also Su Fan's preparation for the future road, that is, to become a nobleman, on this shijie, the nobles are superior to others and crush people to death, and many things are very inconvenient without the identity of a nobleman.
