At about 5 o'clock in the evening, nearly an hour earlier than the scheduled time for dinner, Lu Jiadong took the braised sardines and stir-fried sea cabbage carefully cooked by Luo Fatzi, as well as enough rice for seven or eight people to eat, and came to the cabin where the mysterious people lived.

Lu Jiadong raised a hand, and when he was about to knock lightly on the hatch, there was a sound of "squeak~~" from inside, followed by the sound of a conversation between the two:

"Lao Li, let's go lie down!"

"Hmm, Lao Wang, when did I fall asleep?" the person who called Lao Li seemed to have just been woken up.

"It's been a while, you haven't closed your eyes for two days, let's go lie down, and I'll call you later!" said the man named Lao Wang.

"No, this sonar base array is not very stable, I have to try to debug it again, otherwise even if I take it back, it will be a waste, so what's the use?" Lao Li obviously didn't appreciate it.

"I've already shut it down, Lao Li, you go and give me a good rest now!"

"Lao Wang, why did you turn it off?" Lao Li's emotions were a little excited: "Do you know that this kind of sonar base array has a great loss on the system itself every time it is turned on and off, and it was damaged when the fishermen salvaged it, if we don't pay attention to it, it may really be scrapped."

It's a pity that we finally got such a good thing, and if we don't bring it back completely, the Americans are more than ten years ahead of us in the technology of this sonar base array, our technology is not as good as people, and the conditions are not as good as people, if we don't fight a little more, what kind of national defense modernization will we talk about!"

"Lao Li, I understand your feelings, after so many years, I can finally settle down to engage in research, my mood is as urgent as yours, I admit that our conditions are not good, it is best to send back such sophisticated detection equipment by plane, but our current conditions are not to mention airplanes, even a decent big ship can't be sent.

Otherwise, we can't take this repatriated steamer, at least this ship is fully loaded with nearly 5,000 tons, and there is a certain degree of stability, and the ship is a repatriated assistance group, and it is still politically trustworthy, alas! There is no way, our equipment is too backward!"

Lao Wang couldn't help but sigh, but then he changed his words and continued: "Because of this, I have the responsibility to protect you military talents, Xiao Zhang, I have already let them rest, and now you also go to rest, there is still nearly an hour before the meal, and I will call you then!"

"Wang, you"

"What you and me, this is an order!" said Lao Wang in an unquestionable tone unique to soldiers.

"Even if you are the director of the General Staff Armament Department, you have no right to order me!" Lao Li is obviously also a bull temper, and he does not show weakness to Director Wang of the General Staff.

Speaking of which, there was a temporary calm in the cabin, and after listening to these words, Lu Jiadong finally understood why these people were so demanding on sound, it turned out that they were debugging the sonar base array, and as a military expert, of course he knew that the sonar base array was a highly sensitive detection instrument.

If you want to debug it, the requirements for the environment, sound, humidity, and temperature are extremely harsh, and if you don't pay attention to it, the high-precision parts inside will be scrapped, of course, this also proves that Luo Fatzi said in the afternoon, these people are really from the General Staff Armament Department, and the position is not low, especially that Lao Wang is still a director, no wonder they are so good.

Just as Lu Jiadong digested the content of the conversation between Lao Li and Director Wang, the hatch suddenly opened, and a soldier in his early forties, wearing a military green uniform, walked out.

"Who?

Listening to this accent, Lu Jiadong knew that this was the Director Wang, although so, the stiff and stern tone still made Lu Jiadong very unhappy, but thinking that he was here to deliver food, just find a reason to deal with it.

But just as Lu Jiadong was about to speak, the sonar base array in the cabin, which was already closed, suddenly made a short sound of "squeak~~squeak~~squeak~~", and then the red flash began to flicker incessantly.

"Lao Li, what's going on?" Seeing that the sonar base array was activated for no reason, Director Wang asked Lao Li behind him.

"I don't know!" Lao Li also looked a little at a loss.

When Director Wang and Lao Li were communicating, Lu Jiadong looked at the flashing red light of the sonar base array in the cabin, and the pupils in his eyes couldn't help shrinking, and at this moment, Director Wang also found that Lu Jiadong was looking into the cabin, so he didn't care about communicating with Lao Li, and hurriedly blocked Lu Jiadong's sight with his body:

"What are you looking at, put down your things and go back, or I'll punish you!"

When Director Wang said this, his tone was already extremely stern, obviously not joking, but just as Director Wang said this, the sound of the sonar base array became more urgent, and Lu Jiadong shouted:

"Not good!"

Then he threw the food in his hand to the side, knocked away Director Wang who was blocking in front of him with his body, and rushed to the sonar base array in the cabin, only to hear the sound of "bang", the food was scattered all over the ground, Director Wang was not prepared at all in a hurry, he was hit by Lu Jiadong and stumbled, almost fell, seeing Lu Jiadong rushing to the sonar base array, his hand subconsciously touched his waist, but he touched it and found that he did not bring a gun, so he could only shout:

"Lao Li, don't stop him yet!"

Although Lao Li is about the same age as Director Wang, upright and middle-aged, he is an intellectual after all, and he has no preparations, where can he stop an eighteen-year-old young man like Lu Jiadong, he almost didn't even catch a shadow, and was rushed past by Lu Jiadong, but Director Wang's shouting still alarmed the other cabins, and seeing that his own people were coming, Director Wang pointed to Lu Jiadong, who had already pounced on the sonar base array:

"What are you doing in a daze?

The three young soldiers rushed towards Lu Jiadong in the cabin according to Director Wang's order, and at this time, Lu Jiadong had already come to the sonar base array, only to see that this sonar base array was the size of a suitcase, and below it was a ten-centimeter-thick pedestal, which was covered with accessories for active and passive acoustic wave detection and recording transmission systems.

The flashing red light is in the center of the connection of the detection equipment, and on both sides of the red light, two small cables, one blue and one red, are connected to the sonar base and the detection equipment.

Lu Jiadong observed the sonar base array, judged the wire, and cut it by hand, and it took more than ten seconds before and after, during this period, several people outside the cabin had already come to Lu Jiadong and held down Lu Jiadong's hands to death, everyone thought that holding him down like this would be honest, but they didn't expect Lu Jiadong to stretch his head forward, jump up, and bite the blue wire with his teeth, and several people couldn't help shouting:

"Shut up!"

Then several people tried to hold his head, but they were still a step slow, and as Lu Jiadong pulled hard, the tiny blue line was bitten off in an instant, and the flashing red light and rapid sound stopped at the same time at the moment when the blue line was bitten off. At the same time, several people also pushed Lu Jiadong to the ground.

"I didn't expect to dare to wreak havoc right under my nose, but this is worth it? You guys, quickly handcuff him, and when I get to the shore, I have to treat him as a typical example of counter-revolution!"

Seeing that he couldn't stop Lu Jiadong's behavior, Director Wang looked angry, walking back and forth in the cabin with his waist crossed, and his voice was surprisingly loud:

"I didn't bring a gun when I came out this time, otherwise I would have jumped on you with a shot!"

"Crash me, a bunch of waste, can't even see the sonar self-destruct device, and the face crashes me!"

Director Wang was stunned for a moment, and then immediately jumped up, "I, I, I, I, I

A room full of people suddenly woke up at this time, they are all thousand-year-old foxes, where can they not understand the mystery of this, but the authorities are fascinated, and they are shocked by this advanced sonar device, and this will forget this fatal problem.

"Little comrade, are you saying that you just cut the wire of the self-destruct device? Have you ever seen this kind of sonar base array?" Lao Li, who was standing behind Director Wang, leaned down and asked.

"AN/EQB-16, a new type of sonar base array that the U.S. military equipped in October 1976!" Lu Jiadong replied disapprovingly.

As soon as Lu Jiadong's words fell, Lao Li looked at Lu Jiadong with an incredible look, as if he knew him again.

"Lao Li, this kid is right, you have something to say!" Looking at Lao Li's surprised expression, Director Wang couldn't help urging.

"He's right!"

"What?" After listening to Lao Li's words, Director Wang's expression was also like that of Lao Li: "Didn't you say that even you don't know the model of this sonar base array? You are an expert in this area, how, how?"

"I just wasn't sure if it was the U.S. Army's AN/EQS-16 Sonar Base Array, after all, this model of Sonar Base Array was also developed by the U.S. Army not long ago!"

Lao Li said, stood up, walked to the sonar base array, lifted it gently, and then twisted the nut of the base, opened the bottom cover, and several pieces of burnt yellow high-energy explosives appeared in front of everyone.

Seeing this scene, Director Wang and the others in the cabin all gasped, and a layer of cold sweat couldn't help but ooze out of their backs.

Seeing this, Director Wang's originally upside-down sword eyebrows also soothed, and he scolded a few people who were still pressing Lu Jiadong: "What are you still doing according to the little comrade? Without him, you would have gone to work as underground workers a long time ago!"

Several people listened to Director Wang's words and quickly let Lu Jiadong go, and Director Wang also took a step forward at this time, helped Lu Jiadong up, and then held his hand:

"Little comrade, thank you so much this time!"
