"You've just been given an injection to stop bleeding, and that injection can also put you in a state of low consumption for the next few hours, although the side effect is that you are not very conscious." Mike. Campbell watched the female special forces crouching in front of him pull the needle out of the wound in his severed arm, and these warm words came to his ears.

"Is it okay for you to stay here like this?"

The silver-haired female "ninja" who had cut off his arm had just regained her form and left, but the black-haired female special forces who acted as bait in front of her did not leave, but spent her time helping herself to treat her wounds, and now she began to tie up her companion Kenneth in a big way. Obviously in the midst of a tense battlefield at all times, and it was this kind of hostage rescue battle that was racing against time, but this female warrior was so leisurely, and a strange sense of incongruity made Mike can't help but ask.

"She's enough to deal with the guards alone, and I'm going to secure the retreat route."

It turned out to be a task, yes, it must be a different task assignment, why would you ask such a stupid question, Mike. Campbell laughed at himself in his heart, why did he suddenly be so naïve, is it because the other party is a woman, probably, since the death of his wife and daughter, he has been very helpless against the women who appeared on the battlefield, and now he will be assigned to guard these women...

"What's your code name for the Valkyrie?" In order to keep himself to a minimum, Mike threw out another random question.

"The-Clock."

"What about the silver-haired one?" As soon as he finished asking, Mike felt a little like pumping himself, obviously everyone had said before that it was not owned by Valkyrie's special forces.

Just when the two people who switched offense and defense had a conversation that didn't match, the silver-haired slasher had already touched the side of the big study where Guo Zhouyi and the others were being held.

Although there are very few descendants who can be brought in because of the security relationship, there are still a considerable number of sentry posts arranged near the positions where the core people are held, and the nuclear submarines lurking in the water are also transported personnel and heavy equipment through frogman conveyors SDV and floating hovercraft, so Wang Liumei is still quite confident in ensuring the success of this plan. But even if she is full of self-confidence and the maturity of her mental perversion, Wang Liumei, who can only be called a girl, still feels a sense of irritability in her heart.

This irritability reached its peak when she saw through the windowless study, the only passage where she could see the outside world, --- the glass on the door, and saw that the special forces sitting in the doorway seemed to have not stood up for two or three minutes.

"Brother, go and see if the good soldiers you recruited can stand up and stand guard well?"

Hearing his sister's voice full of sarcasm and resentment, the red dragon smiled bitterly and walked towards the door, he owed this sister too much, so even if his sister didn't let the two soldiers in the house check on and let herself go, he had nothing to complain about; Thinking like this, the red dragon walked up to the guard who was sitting on the chair at the door and was about to give a lesson, when he suddenly found a red line on the guard's neck that was only obvious at this distance, and a wordless fear instantly filled the red dragon's body, and he hurriedly prepared to run back to the study, but he stumbled on the chair and made a clanging sound.

The people in the study, including Wang Liumei, all looked at the source of the sound.

"Liumei...

Only had time to call out his sister's name one last time, and before the last two words could be uttered, the red dragon suffered the same fate as the guards at the door--- heated high-frequency oscillating blade cut through the skin and through the gap in the cervical vertebrae, separating its head from the body that carried out the order. He took a few more steps forward, and it wasn't until the red dragon and the guard at the doorway fell to the floor that the organs of thought were completely separated from the body of the execution, and blood erupted on the floor like a river.

"Brother!!

Wang Liumei screamed and was about to charge at her brother, but one of the two special forces guarding the room had already pulled her behind her, and at the same time raised his gun to shoot at the blood-stained enemy near the door. A sharp wind of knives swept through the room, and the rescuer who burst into the room hurled his high-frequency blade at the other special forces who had almost grabbed Kamitov with one hand as they flew across the walls in a gesture beyond common sense.

The kidnapper, who tried to grab Gamilov, quickly crouched downward, allowing the thrown blade to make only a cut in his shoulder, and he kicked the leg of the chair where Gamitov was sitting, causing the old man to fall towards him. In this way, the general of Titans would fall in front of him, in front of his own gun, and he would not dare to do anything more--- but almost in the next moment, the hijacker's thoughts were interrupted with severe pain. The neurotoxin that only oozes from the concussion blade after it stops working takes less than two seconds to stage the hijacker's spinal nerve transmission, causing him to twitch on the floor.

"Johnny !!" The special forces who protected Wang Liumei behind him let out a low sorrowful scream, and continued to shoot at the phantom galloping on the wall, but he suddenly felt a pain in his wrist, and looked down at it, there was a small needle stuck in the only bit of bare skin, and he tried hard to look back, but he only felt that his consciousness was constantly steaming, and finally fell to the ground.

"You..." Guo Zhouyi's eyes widened, and he opened his mouth wide to see that the silver-haired girl president who was tied to him had just fired a poisonous needle from his left eye and killed a hijacker.

"I'm not there when the dance starts." What answered him was the black-clothed female warrior who killed three people and fell to the ground.

Immediately, the black-clothed slayer removed his mask, revealing his face inside.

"You。。。。。。 She..... Guo Zhouyi looked at the two people with the faces of "Ouyang Ying" in surprise.

"Reintroduced," Gamitov was unroped. pointed to the woman who had been tied up beside Guo Zhouyi, "One of the elite special forces of the Federation, a member of Valkyrie, the best master of disguise, [The-Water] - Norma." Sheffield. ”

"There's no time for small talk, I bet the two of them had already set off a bunch of alarms when they fell," Ouyang Ying knocked Wang Liumei, who had collapsed to the ground, unconscious, and then put on the mask again, and said in a rapid metallic voice, "I have to go now." ”

"Well, hopefully the rest of the troops will go well."

When Gamiltov and the others escaped, in the blue ocean outside Hawaii, the nuclear submarine Oklahoma belonging to the Titans Rebels was moving into a silent submarine after launching the last SDV.

"I don't understand...

Opening his closed eyes, Oklahoma's sonar chief took the headphones off his ears. He looked at the sonar instrument panel through the heads of the two crew members on duty--- all the devices were functioning normally; Once this was confirmed, he placed the headset back on the monitor frame. The dim lighting of the sonar room shone a shrug and wry smile, and Yang Xiao, who was sitting on the duty seat, felt a sense of despair.

Even in the veterans-filled lineup of Titans non-commissioned officers, the 47-year-old sonar chief at the time was quite senior. Yang Xiao knew that when he was still a toddler, the sonar chief had already boarded the submarine. Sonar is like the ears of a ship, in terms of interpreting sonar, the sonar chief is undoubtedly Yang Xiao's senior, but Yang Xiao feels that the sonar chief lacks sensibility. Sonar chiefs have a habit of throwing their imagination aside and accepting the judgment of machines without thinking. However, he felt that no matter how advanced the technology was, the crew of the submarine would still need instinctive intuition and ingenuity.

"This is the sound that the passive sonar had detected thirty minutes ago -- it was not the wavelength of the waterjet engine, and the sound was a bit flickering."

A novice sonar who had just been assigned half a year ago, it was impossible to criticize the sonar chief in person, perhaps it was determined by the culture of his ancestors, while entering the template number of the audio recording on the analysis screen, Yang Xiao spoke cautiously.

However, there is a certain pattern to the sound received. A long time ago, some nuclear submarines emitted this sound. If only it could be compared to the Headquarters' database... ”

Explain that an irregular sinusoidal curve appears on the screen, and although the ship's database shows no data matching, there is no guarantee that this is not the sound of the submarine's propulsion system. Today's submarines are sailed with a low-noise fusion jet engine. However, the silent propulsion system has been the subject of research since the Cold War between the United States and the Soviet Union in the old century, and the sound shown by this curve is similar to that of the early silent propulsion system.

If he hadn't worked hard to find the old records from the old database of submarine school graves, Yang Xiao might have regarded it as a natural phenomenon. He continued to improve the precision of sound resolution, but what the sonar chief said to him was a sentence mixed with a sigh: "I said, Yang Xiao... ”

"It's good to be enthusiastic about research, it's good to be studious, and I admit that your ears are bright enough. However, this is not a club activity that students are doing--- will there be a nuclear submarine of the old era? It is true that some ships of the old century are still in service today, but their equipment has long since been improved. Do you think that the old antiques that have been excluded from the ship's database will still be used by anyone today? ”

Standing behind Yang Xiao, the sonar chief put his hand on his fat waist and reprimanded loudly:

"The Navy doesn't give you expensive equipment to satisfy your interests."

These heavy words smashed into his head and face, making Yang Xiao feel that the water pressure covering the hull of the ship was nothing more than that. He lowered his face, which was covered in the word dejected, and put his headphones back on after answering "yes". With his nose puffed out and his stomach tucked up, the sonar passed through the back of the seat of the crew on duty and left the sonar room, which was as narrow as a birdcage.

Inside the ship under the normal combat deployment, it was again engaged in a headless rebellion mission, but the atmosphere was as gentle as sailing training, probably because I was told that no enemy diving troops would infiltrate this sea area. Sensing that he had rapidly lost interest in the source of the unknown sound, Yang Xiao sighed. When his colleague, Galen, an analyst with the nickname "Numbers", heard this, he comforted him by saying:

"Don't take it to heart, the sonar chief is a sports school that made a name for himself in college with basketball, and of course he can't get along with someone like you."

Taking off his headphones, Galen raised the corners of his mouth: "However, I also don't think it will be an antique-class nuclear submarine." This place has been sealed off by friendly forces, and by the time the rest of the Federation's diving fleets reacted, we were long gone. ”

After chuckling like this, Galen put his headphones back on, putting an end to the small talk.

Will it be that simple, Yang Xiao whispered in his heart, and then re-examined the various devices on the monitoring table.

He examines the underwater exploration monitor, which can reproduce the conditions of the seabed in CG, and the audio screen, which uses the reflected waves of active sonar to project the shape of the target. Active sonar, which is placed at the bow and sides of the ship at the same interval, filters out unwanted sounds and concentrates the exploration sound in the headphones. The "superfluous sounds" refer to the mechanical sounds emitted by Oklahoma itself, as well as the sound of fusion engines mounted on both sides churning seawater.

In the next instant, the muffled sound of steel colliding shook Yang Xiao's eardrums.

The hand pressed on the headset tightened, and he looked at Galen beside him, who seemed to hear the same voice. Yang Hao, whose face was blue, operated the monitoring station, extracted and corrected the problematic sound, and then he turned his head to stare at the circular screen of the sonar radar. It didn't take long for orange highlights to appear on the screen, and a short, beeping warning sound reached his ears.

The comparison result was none. Although no propulsion sound was detectable, something was gradually approaching from behind the starboard side. The distance was less than a kilometer, and the sound of unknown metal continued to come, and Yang Xiao shouted: "This is the sonar room!" ”

"Directions one, three, two. The target velocity is set at thirty knots!"

The sound of metal dragging the wonderful syllables was still ringing, and when Yang Xiao and Galen were doing their separate identification operations, the captain and the sonar chief were in the sonar room together.

"What do you think this is?"

Facing the captain who bowed his head and questioned him, Yang Xiao replied nervously:

"I'm not sure. It's not the same as the opening and closing of the *launch tube, but it still sounds like metal. I think it's the sound of the joints...... It's probably like the sound of a machine's joints working! ”

At this moment, Galen screamed, "Goal, speed up!" ”

"Eight hundred. I'm coming straight toward here! ”

800 meters, which is already less than the safe distance of *, what does the other party want to do?!

The flashing marker on the radar rapidly approached the center of the circle, exceeding the speed of forty knots, which had already exceeded Oklahoma's maximum speed in the water

"Full speed, rudder to the end!"

At the same time, the sonar chief shouted: "Active sonar, sound waves!" The voice sounded, and Yang Xiao immediately pressed the active sonar button on the monitoring station.

With a bang, the horn screeched, shaking the Oklahoma hull. The reflected waves, which travel four times faster than in the air, were mechanically analyzed, and the outline of the target was projected on the audio screen, which could be felt, and everyone in the scene breathed.

Since the two sides were almost at the same depth, the shape must have been seen from the front. However, the silhouette of the target is very unusual, and it is completely detached from the concept of a ship due to its flat diamond shape, and more than that, the target changes shape all the time and approaches at high speed in the sea.

Obviously it didn't use the fusion water jet engine, so why could the other side move freely in the sea? At the moment when Yang Xiao's head became blank, the sonar chief who pushed him away got up and took the dashboard, and issued a "Distance, one hundred and sixty!" If you go on like this, you will hit it directly".

"Collision Alert!"

The captain's near-screaming voice rang in his ears. Then, the sound of steel tearing through the hull of the ship, and Yang Xiao was thrown out of his chair.

Galen was also ejected, and the captain slammed into the wall along with the sonar chief. Just as the alarm sounded and the lights flickered, Yang Xiao heard the sound of the ship's hull being crushed, and his consciousness disappeared.
