Arthurstone didn't look in a hurry, and said: "Those things are formed under a special magnetic field, but there must be a real thing behind them, and as long as we avoid that real thing, our submarine will not be physically damaged." However, it is difficult to predict what impact the interference of strong magnetic fields will have on the safety of submarine equipment and personnel. ”

"What's that thing you're talking about?" Ivan asked.

Arthurstone said, "It's a pyramid. ”

"Pyramids?" Boris's eyes widened, "What are you kidding?" We are now on the edge of the basin of the South Pacific, are the Maori descendants of the ancient Egyptians? ”

"Do you know where we are now?" Stone asked.

"Of course I do." Boris glanced at the charts and positioning system, "Now about 150 degrees west longitude, 30 degrees south latitude, the eastern edge of the South Pacific basin, and a little further north to the Tubuai Islands." ”

Stone nodded and said, "You can imagine if we were connected to the center of the earth in a straight line, where would the other side of the earth be?" ”

Boris had a globe in his head, imagining a straight line passing through the center of the earth from where they were, and muttered: "The corresponding latitude and longitude are 30 degrees east longitude and 30 degrees north latitude, and there should be"

He searched for his memories. For those who have been running on the sea all year round, they can remember the location of each island, but they have very little knowledge of the geography of the mainland.

"That's Egypt." Ivan said.

Boris seemed to think of something, and said, "Don't tell me that the pyramids of Egypt have fallen from the other side of the earth." ”

"It's not like it to fall, but they've made one on the other side of the earth." Stone said.

"Who did this?" Boris wondered, "I don't believe those pharaohs would have come to Polynesia in warships. ”

"It's hard to say, maybe they got the stone people on Easter Island." It was said.

"Come on, I still believe in Stonehenge, forget about Easter Island."

"But Easter Island isn't far from here, isn't there any miracle in the South Pacific that wasn't done by the same people?"

Everyone said word by word, only Ivan didn't speak, he looked at Stone, knowing that he probably wouldn't say more news, anyway, if something happened, none of the people in the boat could escape.

"Ivan, the magnetic interference is getting stronger and stronger, and they are getting closer and closer to us."

"Drive at full speed, go as far as possible in the direction where magnetic interference is weak, and rush over at full speed." Ivan ordered.

"Do you want to float to the surface first?"

The speed of this old submarine is much slower than that of modern submarines, and if it can float to the surface and sprint again, the speed will be increased by at least three knots.

"It's too late." Ivan said.

"Okay, full speed ahead."

Everyone stopped joking at this time, and looked like they were waiting for battle, and even Boris put away his usual playful expression and angry temper.

The submarine drove at a speed of thirteen knots towards the place where the magnetic interference was weakest.

If one could see the deep sea at this time, they would see that in the deep blue sea, there was a circle of transparent inverted pyramid-shaped objects with a light blue glow, suspended in the sea like icebergs.

An old black submarine, like a giant whale, silently crashed into those strange things.

The suspended inverted pyramids were also moving at a breakneck speed, merging, and seemed to devour the submarine.

"Ivan, the magnetic probe is completely disrupted, and we seem to be surrounded by a powerful and disordered magnetic field!"

"Fortunately, in such a magnetic field, our instruments and equipment did not fail!"

"Ivan, the sonar detection has responded, there is something ahead!"

"What's that?"

"It's an iceberg! No! Not an iceberg, a pyramid, an upside-down pyramid! Same as those seen on the sea! ”

"Turn the rudder! Avoid it! ”

"Yes, twenty-five on the left side, three on the front!"

"Ivan, we can't seem to avoid it, it's still right in front of us!"

"Could it be another?"

"No, sonar shows only one."

Ivan looked at Stone, who was lost in thought.

"It's about to bump in, Ivan!"

"Turn the rudder again!"

"Twenty on the left side! Oh my gosh, it's still there! ”

"Retreat, urgently retreat!" Ivan made a decision on the fly.

"Yes, urgently retreat."

"That guy seems to be following us!"

"Leave it alone, keep back!"

"Yes, keep back!"

"Yo ho!" The person in charge of sonar detection cheered, "It seems to have been shaken off." ”

The crew was happy and no longer as nervous as they had just been. But Ivan didn't relax at all, how could a behemoth suddenly disappear from the sonar detection?

Sure enough, the person in charge of the sonar soon shouted in a panic: "It's behind us!" ”

Ivan immediately ordered: "Turn the rudder, urgently advance to three, and go at full speed." ”

The crew followed the command. Although they are all veterans, the submarine keeps changing speed and direction, which makes everyone in the boat feel that the blood is surging, after all, there has not been such a situation for many years. Ivan looked at Stone and saw that there was no change in the expression on his face, as if he had just eaten breakfast at the table.

"Ivan, it's ahead!"

"With a torpedo, blow it up, Ivan!" Boris yelled, "It's too late to get closer!" ”

Ivan had no choice but to order: "Launch the torpedo!" ”

"Yes, launch a torpedo!" Boris became excited, and his face turned red.

The speed of the torpedo is much faster than that of the submarine, reaching a speed of 40 knots, that is, the speed of about twenty meters per second. According to the sonar detection, the distance between the change of direction and that thing just now is about two kilometers, and it can hit the target in less than two minutes.

But after only a minute or so, the sonar observer exclaimed, "It's out of the way!" ”

"What?"

This thing will also dodge torpedoes? That means it's manned or intelligently driven. Such a large thing, suspended at the bottom of the sea, capable of navigating in the sea at a depth of nine hundred feet at a speed of about twelve knots, which country made a strange submarine?

The crew was puzzled.

Ivan didn't want to think so much, because if he got closer, after a safe distance, firing a torpedo again would be tantamount to suicide.

"Boris!" Ivan yelled, "Shoot all the torpedoes for me, cover the front of the submarine at an angle of sixty degrees, up and down, left and right, and see where he is hiding?" ”

"Good Ivan! You're kind! Boris exclaimed excitedly.

The submarine kept adjusting the angle of the torpedoes, and all the remaining thirteen torpedoes were fired.

"Hell yes!" The crew in charge of the sonar shouted.

"What's wrong?"

"That guy is gone!"

"What?"

"Not only is that guy gone, but so are our torpedoes!"

"How is that possible?"

"Is the sonar broken?"

"It's possible. However, "

"But what?"

"Like, it seems that the torpedoes are back thirteen, yes, it's our torpedoes oh my, our torpedoes are coming at us! They're going to attack us! ”

"What did you say?" Boris yelled.

"Get out of the way!" Ivan also yelled, being hit by a torpedo is not a joke, you must know that a torpedo that explodes underwater is much more powerful than a missile exploding on the ground, and a torpedo can scrap a destroyer.

"We can't avoid it, Ivan! Thirteen torpedoes from thirteen directions blocked all our routes. ”

There was a deathly silence in the command module, save for the beeping siren of the sonar sonor, and thirteen green dots on the instrument screen, moving closer to the center.
