(Demon Shao: There were mistakes in the previous chapters, and the protagonists didn't take a nuclear submarine, but a Ming-class submarine, and there was one place that didn't change back.)

After 478 hours in the deep sea, the entire experimental submarine entered a state of electronic silence, cut off all contact with the base, and began to test silent diving.

The solemn atmosphere in the entire submarine gradually relaxed, and as long as we looked at the experts of the Chinese Academy of Sciences of the country, the professors of the National Defense University, who had had time to come out of the special laboratory and talk cordially with the soldiers, and the smile on the face of Captain Sun Jing, everyone understood that the most dangerous mission was over.

Silent diving is no longer a dangerous task for these officers and men in the submarine who have received strict training and have rich sailing experience, but an easy trip. All they have to do now is to assist the expert's assistant and collect all kinds of data.

The submarine was a hundred meters below the sea surface, quietly sneaking, Sun Jing nodded with satisfaction, although he didn't know what kind of technical upgrades and modifications this experimental submarine had undergone, but it was obvious that this experimental submarine, while maintaining the propeller friction propulsion in the seawater, effectively reduced the shock wave and noise, if this technology can really be popularized in the naval forces in a large area, China's "Ming-class" submarine, can take off the "ocean echo" This is not glorious, It even represents the title of the price of death!

"Report," one of the wheelmen reported to Captain Sun Jing, "the battery power of our boat has reached the warning line, and it needs to be charged immediately!" ”

Sun Jing glanced at his watch and ordered, "Float at medium speed!" ”

According to the procedure, the charging is to start the diesel generator in the submarine, which needs to burn a large amount of oxygen when it starts, so the submarine needs to float close to the surface of the sea, and extend the periscope and air intake valve above the command station to the surface of the sea to suck in air.

The test submarine slowly floated, and at a height of fifteen meters above the surface of the sea, the periscope and air intake valves of the submarine were raised at the same time. The diesel generator set in the submarine starts to work with a rumbling sound, swallowing a large amount of oxygen in the diving cabin, and at the same time continuously transmitting electrical energy to the submarine battery pack.

Sun Jing stretched out his hand and gently tapped on the command platform, to be honest, he really liked this test model based on the prototype of the "Ming-class" submarine, and this submarine has been improved for problems such as the submarine's charging time is too long, and it is easy to expose the target and affect the assault mission, which is at least 30 percent less charging time than the ordinary "Ming-class" submarine. You must know that on the real battlefield, this thirty percent charging time can often determine the victory or defeat of a submarine or even a battle!

Although China already has nuclear submarines, according to Sun Jing's prediction, the Chinese Navy will still need conventionally powered submarines as the main force of its submarine force for a long time, and improving the combat effectiveness of conventional submarines is the issue that these submarine captains are most concerned about.

"I can finally bring back my brothers with me, but ...... This invites everyone to eat and drink for three days, this ...... Is it okay to ask them to eat beef noodles every day and drink free noodle soup? ”

Captain Sun Jing, who has both the courage of a man and the slippery head of a scoundrel, has begun to secretly calculate in his heart how to avoid the danger of his wife's total annihilation, at this time, a sudden terrible alarm sounded wildly in the command room, and several red signal lights representing the most dangerous in the submarine emitted a blood-red light that flickered and dimmed.

Something happened!

Cold sweat soaked Sun Jing's military uniform in an instant, and he quickly judged in his heart that the submarine was stable and there was no sign of external force, and now the submarine had floated to a place fifteen meters away from the sea surface, and it was even more unlikely that there would be fatal problems such as damage to the pressure hull, the diesel generator set was still working, and the sound was normal, and the signal light of the fire alarm was not on, indicating that there was no fire in the submarine......

One of the columnists' eyes widened and hissed: "Report, the air pressure in the No. 1, No. 2, and No. 3 cabins is out of balance, and according to the detector, the oxygen content in these five cabins has reached a dangerous level!" ”

Before the barbaron's voice fell, another bariston roared: "Report, the air pressure in cabins 4 and 5 is out of balance, I don't know why, the oxygen in the cabin is rapidly depleting!" ”

Sun Jing snatched the microphone of the communicator and roared wildly: "Report to me immediately, what happened!" Take your emergency rescue team, go to cabin five, and immediately get those experts in the laboratory back! ”

The warrior song shouted, "Yes! ”

But immediately, the warrior song shouted at the other end of the submarine: "Report, I don't know why, the hatch can't be opened!" ”

"If you can't open it, you have to open it for me!" Sun Jing's face was as hideous as a ghost at this moment, and he hissed and roared: "I don't care what method you use, even if you blow up the cabin of the submarine with a torpedo, you have to open the hatch for me!" Now they are running out of oxygen in their cabins, they will suffocate to death at any time, they are academicians of the Chinese Academy of Sciences, professors of the National Defense University, they are all treasures of our country, even if they sell our dozens of cheap lives, they can't afford to pay for it!! ”

"Report!"

One of the bartenders shouted wildly: "Cabin 1 has become negative air pressure!" ”

Sun Jing only felt that his legs were weak, and he involuntarily fell to the ground, once the cabin became negative pressure, negative pressure would be generated, even if Zhan Xia Ge and the emergency rescue team he led were the reincarnation of King Kong, I was afraid that I would not be able to open the No. 1 hatch.

"Report," the second person was silent for a long time before he whispered, "The oxygen concentration in cabins 1, 2, 3, and 4 is ...... Zero! ”

Sun Jing was really stunned, he knew that those national treasure-level experts were all dead! He sat there dumbfounded, muttering to himself, "What the hell is going on, why did the oxygen concentration in the cabin drop to zero after only two minutes?!" ”

The whole command room was silent, even the sound of the diesel generator was gone, Sun Jing's expression moved, he jumped up and slapped himself twice, he hissed: "I understand, I understand!" It was our submarine that the intake valve did not open! Otherwise, the oxygen in the five cabins of our submarine would not have been consumed to zero degrees in two minutes, and there would be no negative air pressure in our cabins! my sister, we've done so many experiments, we've gone through so many dangers, we've overcome one obstacle after another, how can we be about to go home, face our superiors right away, and proudly tell them that we've successfully completed the task, but we are ...... because of a small air intake valve It's all over?! ”

Tears and snot spurted out of Sun Jing's face together, he slapped himself hard while crying, and in the loud slap sound, a thick layer of blood was sprinkled on his face, and he hissed and cried: "Sun Jing, Sun Jing, aren't you fucking awesome?" Don't you think you're a good person? Why did you have diarrhea when it came to the critical moment? Isn't it because the diesel generator set is constantly consuming the oxygen in the cabin, but the oxygen from the outside is not being supplied? Shouldn't you immediately think that the intake valve is failing? The failure of this mission, the lives of so many brothers, are all ruined by your stupidity, your stupidity!! ”

"Captain, what are you doing?" Carrying an extra-large pair of pliers in his hand, his face was covered with sweat and oil, and Huang Zhipeng rushed in, he grabbed Sun Jing and roared: "Big brother, calm me down, we have an accident now, if you lose control again, we will be all finished!" ”

"Finished? Yes, it's over, we're done, we're all done! Sun Jing grabbed Zhan Xia Ge's hand holding the pliers, and hissed: "If you treat me as a big brother, you will raise the guy in your hand and smash my head down, I am sorry for you, I killed you all!" ”

Zhan Xia Ge glared and shouted, "What the hell is wrong? ”

"Now there are fifty-seven officers and men on our ship, plus those experts and their assistants, a total of seventy people, and now the ones who survive are these people in our command room and the brothers of your emergency support group!" Sun Jing wiped the blood and tears from his face fiercely, and shouted: "I can tell you that now cabins 1 to 5 have all become negative pressure, all our ways out have been blocked, and we can't escape!" If we can't wait for reinforcements, don't look at us as if we're only fifteen meters above the sea, but we're all going to die here! ”
