In the silent sea, Jiang Ming took the lead, and two aliens followed him at high speed.

The submarine was far from its hideout, and several stinging fish had been swimming around it as surveillance.

He hurried non-stop, and it was dark at night.

This is a conventionally powered military submarine, that is to say, it uses a diesel engine and a battery as the power, and the speed is very slow.

Under normal circumstances, it crawls slowly in the sea at a speed of three or five knots, and the knots are the unit of speed, one knot is equal to one nautical mile, and one nautical mile is 1.852 kilometers.

That is to say, this kind of submarine usually sails at a speed of less than 10 kilometers per hour underwater, and even if it enters a combat state, it can operate at a maximum speed of more than a dozen knots at full speed.

But at this speed, the battery is drained in about an hour, and it needs to be recharged before it can sail again.

Not to mention that this conventionally powered submarine is not as fast as a motorcycle, and under normal circumstances, the speed is not as good as that of an adult alien.

What is more important is its diving depth, which can only be dive to a depth of three or four hundred meters for conventionally powered submarines, and even if a nuclear submarine fights at a maximum depth of only about one thousand meters.

No matter how deep it is, it won't work, the huge water pressure will interfere with the weapon system, not to mention the guide to hit the north, anyway, it will definitely be inaccurate.

Therefore, conventionally powered submarines are also suitable for peeping, waiting for rabbits, and sneaking around to do some unseemly things.

Nuclear-powered submarines are highly destructive, but in Jiang Ming's view, there is still nothing to be afraid of, because this kind of thing has no room for use in the face of aliens.

To sum up, Jiang Ming is very confident in water dominance, and he doesn't take human combat effectiveness in water seriously at all.

They are okay fighting in the water, and fighting against the aliens and other zergs is undoubtedly self-defeating.

After a few more swims, a behemoth appeared in sight.

This conventionally powered submarine resembles a whale, is quiet, and highly concealed, but any hiding in front of the pervasive Zerg is a joke.

At a cursory glance, Jiang Ming found that the submarine was at least more than 70 meters long, larger than two python aliens, and there were English letters printed with white waterproof paint on the tail of the ship.

Translated: Almoz-class conventionally powered military submarines.

The Xenomorphs had locked onto the submarine, but the submarines didn't know they were approaching.

Now submarines are detected by sonar, and the signal is transmitted in the water, and it will return when it encounters obstacles.

The signal is transformed and amplified to become sound on the screen or in headphones.

The distance can be determined according to the round-trip time of the signal, the nature of the target can be determined according to the pitch of the voice, and each sound is different from steel, rocks, fish, etc.

Echolocation technology like bats, but more advanced than it.

If the target is moving, then the echo tone will change due to the 'Doppler effect'.

The pitch keeps getting higher to indicate that something is approaching the submarine, and the pitch is getting lower to indicate that the target is moving away.

Because of this, Ekina and the other alien did not approach here in a straight line, but swam in a meandering curve, creating the illusion of two fish swimming around on the submarine.

He is more than five meters long, and the other alien is less than three meters, this type of body type cannot be said to be common in the sea, but it is definitely not rare.

Therefore, the people on the submarine would never have imagined that it was the alien who was approaching, and the ability to do this was due to the accumulation of knowledge when he was studying in the past.

"Knowledge is a weapon!"

Jiang Ming sighed secretly.

If he didn't know the principle of sonar, he would definitely rush straight to it, and he would definitely be discovered.

When the time comes, a few torpedoes from the submarine will blast over, and even if it doesn't kill him, he will be disgraced and flee with a wolf.

But after knowing everything, he was able to use these things to make an ambush, and the python alien was ordered by him to stay a few nautical miles away, and then deliberately approached the submarine in a straight line, wandering for a while and then moving away.

Sure enough, the humans in the submarine were fooled, they had tracked the python alien before, but it hid in the sea more than 600 meters deep, and this submarine could only dive three or four hundred meters deep, and there was nothing to be done after firing a few torpedoes and missing.

The anaconda alien size is too conspicuous, even the ocean is not much so big, and humans confirmed it as soon as they found it.

Now the anaconda alien blatantly roamed in the distance, and to these people it seemed to them that the beast was waiting for an opportunity to take revenge.

"A beast is a beast after all, a lowly species without intelligence, no matter how powerful it is, it can block a missile? It's really unworthy of lifting shoes for humans! ”

In the submarine command room, a handsome-looking American officer leaned back in his chair and leisurely sipped his coffee, and said in a contemptuous tone.

A green strip on the screen slowed down, getting farther and farther away from the submarine.

"Report, Monty Python is locked, parameters are fed into the loader, torpedoes can be fired."

Sitting in front of the screen, a soldier crackled on the keyboard with both hands, staring at the screen with his eyes, and said loudly without twisting his head.

As if he hadn't heard it, the officer took a sip of coffee and smacked his lips: "Such an authentic Blue Mountain coffee, after drinking it, you have to wait a month before you can go ashore, it's a pity." “

Shaking his head sadly, a touch of melancholy appeared on his handsome face, and he sighed.

Suddenly, he sat up straight and changed his tone, and said sharply: "What are you waiting for if you lock it?" up that one and smash it! ”

After speaking, he regained the ease and comfort he had before, leaned back in his chair and sneered softly.

"A nascent species? Oh, it's nothing compared to human beings, and it's a joke that the poor Celestial Empire has such a big event! ”

"Boom, boom!!"

As soon as he said to himself, a dull explosion suddenly sounded outside the submarine, and the entire submarine shook violently a few times, and the lights inside flickered and went out.

There were several exclamations and women screaming in the command room, and there was a commotion.

The young officer's spotlessly clean military uniform was stained with coffee.

"What's going on?"

"Report! The submarine was attacked, there were four rifts, and the sea water was pouring in! ”

A panicked voice sounded, and he said hurriedly.

"What ?!!!"

The handsome young officer slammed himself up from his chair, his voice raised an octave to a sharper and thinner voice.

His face was full of fear, and he was momentarily disproportionate.

"Why are submarines being attacked? Who attacked? With what? ……”

Countless questions flashed through my mind in an instant, but none of them were answered.

There was a commotion in the submarine, with piercing sirens sounding everywhere and people shuttling through the passages with anxious faces.

Yelling, roaring, and issuing orders one after another.

The source of the explosion was a bomb bug, which was naturally Ena's masterpiece.

However, the power of the bomb worm in the water was greatly reduced, the blast wave did not work, and the acid was diluted and washed away by the seawater in just an instant, and only four large holes in the submarine were blown up.

"Squeak!!"

Another piercing metal screech came from the top of the submarine, like scratching a blackboard with your fingernails, making your scalp tingle.

The human beings in the submarine forgot their movements for a while, and looked up blankly at the top.

Eina jumped on the submarine, bent down and pointed at the top like a knife and quickly ran from head to tail, slashing hard!

Although it did not penetrate the submarine hull, it also gave it a V-shaped metal dent.

"Crunch!"

He stood in the middle of the submarine with his palms folded and suddenly plunged into the dent in the shell, and then forcefully stretched it out to the sides.

The thick metal shell was torn by him, making a tooth-aching screeching sound.

The gap at the top was getting bigger and bigger, and the sea water poured into it fiercely, and Jiang Ming saw through the misty water curtain the faces of the humans inside full of despair, as well as frightened eyes.

And the humans inside also saw a huge xenomorph standing on it through the hole in the top, with an oval head diagonally facing them, and the corners of their mouths pulled back to reveal a hideous smile.

With lightning speed, he tore several large holes in the top of the submarine, watched as a large amount of seawater poured into it, and listened to the desperate wails and screams.

He stood at the top and looked down at the inside of the submarine, opened his mouth and whispered a sentence of English that he hadn't used for a long time to the American soldier inside, then jumped down and swam to the side.

"Good, Luck (Good good)"
