The latest website: "Guard 1, lower the altitude, slow down the speed, follow me, don't rashly advance!"

"Second Guards, change the formation, unfold in a vertical column, and so on for the latter, widen the distance, and don't stick too tightly!"

"There is a strong undercurrent gushing out of the cave on the right, everyone should pay attention to adjusting the power and try to avoid hitting the wall!"

…

From the short-distance communication system and earphones, Meng Lei's stern commands were constantly heard.

In the dark and narrow deep-sea rock tunnel, five submarines lined up in a row, moving slowly under the command of Meng Lei.

From the third day after departure, Meng Lei discovered that,

I was too optimistic about the difficulty of the voyage of this wasteland trip.

In addition to the alien sea monsters lurking in the dark, the complex sea environment is also one of the biggest obstacles to the difficulty of the fleet!

Unlike the passage that led to the molten rock outpost last time,

The closest channel to the hydrothermal wasteland sea area suddenly became rough and complicated after about 500 kilometers away from Xier City.

The exposed rock formations around it were smooth and smooth, inexplicably turned into sharp rock thorns hanging upside down.

In the densely packed huge holes on the surrounding rock walls, undercurrents are constantly gushing out.

It is like a sudden passing wind. If you are not careful, it will sway the submarine to the left and right, and it is difficult to maintain stability and balance.

Not to mention the rookie captains like Zhang Chao and Lin Ming, even Meng Lei, who has thousands of kilometers of driving experience, inevitably suffered a few secret losses.

On the third day of going to sea, the Sea Locust, which had just finished maintenance and repair, was already scarred on the surface of the shell, and there were a lot of scratches caused by collisions.

Fortunately, the specially reinforced shell structure,

It is not enough that under this level of collision, serious damage will occur, and the overall structure is still intact.

It's just that the pitted surface looks a little embarrassed.

However, Meng Lei still did not dare to take it lightly and strictly controlled the overall speed of the fleet.

And always rush to the front of the queue to clear the way, to warn everyone in advance to avoid being harassed by potential hidden dangers.

As a result, the sailing speed will undoubtedly drop a lot.

Under normal circumstances, it can reach a speed of thirteen or four kilometers per hour. In this sea area, it cannot even reach a speed of five kilometers per hour.

A whole day has passed, and the fleet has only gone out less than 60 kilometers.

The captains responsible for driving the submarine were also mentally exhausted and in very poor condition.

This feeling is even more tiring than driving at high speed for more than ten hours on land. First of all, it is due to the visual fatigue caused by insufficient light.

Secondly, in order to avoid hitting the wall, we must always be on the lookout for the sudden underwater undercurrent,

The spirit is always in a state of high tension, even the iron man will inevitably feel tired.

In the Sea Locust, Meng Lei sat on the leather seat in the command room, his eyes were solemn, and he kept flashing back and forth between the sonar display screen and the projection in front of him.

The automatic navigation system and the automatic driving system of the submarine cannot play any role in such a complex and changeable marine environment.

To sail safely, you must take manual driving.

He has been driving for eleven hours straight since he woke up in the morning.

Apart from taking a proper rest during lunch time, he was stuffed in the cockpit the whole time, and he seldom even went to the toilet.

The coffee on the table was refilled cup after cup,

The water in the body turned into cold sweat and was excreted out of the body in the thrills again and again.

The scene in front of you, except for the endless darkness, where you can't see the end at all,

Only the occasional churning and rising bubbles slowly floated with white flocculent fragments of organic matter.

The whole world looks extremely dry and desolate, as if driving in the wilderness of the universe, without the slightest vitality.

It was also the first time that Meng Lei encountered such a complex marine environment and felt unprecedented pressure.

The reason why he didn't rest for so long was because he wanted to cross this area as soon as possible.

But this road seems to have no end, no matter how hard he tries, there is no hope at all.

"How long does it take to go on like this? If the environment is like this before arriving in the hydrothermal wasteland, let alone half a month, you won't be able to reach the Barona Colony in a month!"

He picked up the coffee cup on the table and took a deep sip.

The rich bitterness hit the taste buds wildly, and the strong sensory stimulation slightly dispelled some mental exhaustion.

Meng Lei sighed silently in his heart, really helpless.

As for the map of the hydrothermal wasteland sea area, he has no shortage of maps, even more than one.

In addition to the paper map that Ning Wen bought from the store, when he was about to set off, Roger also sent him a new electronic map, which recorded the sea environment of the hydrothermal wasteland in detail.

However, there was no clear map for the nearly 1,000-kilometer waterway before reaching the hydrothermal wasteland, which could point him in the right direction.

This distance can only rely on the navigation and positioning of the submarine, and according to the signals provided by the sonar beacon stations along the way as a guide, we can travel in the dark underground ocean.

Therefore, how bumpy the road ahead will be, no one knows how long this road is, except for those who have sailed in this sea area.

In addition, the signal provided by the sonar beacon station is not completely stable.

Once the beacon station fails and the signal is lost, it is very likely that inexperienced people will be completely lost in this underground cavity crack structure.

This is also one of the potential dangers that may be encountered during deep-sea navigation.

At ten ten in the evening, the fleet passed through a huge seafloor rift.

As if there was a god-like existence, the sharp blade in his hand cut off a rock formation, and opened a gap in the earth's crust.

After passing through the crack, the scene in front of him finally became clear.

The searchlights on the outside of the submarine no longer had any feedback, and everything was hazy.

That feeling made Meng Lei seem to have returned to the boundless void where his birth point was when he first crossed.

The only difference is that the sonar detection system at that time was unable to detect high-altitude conditions due to its limited range.

The end of the sound wave transmission is completely empty nothingness, which is more empty and dead than the universe.

But now, although the sight is similar to the original scene.

However, the sonar display can clearly feedback that the height of about 600 to 700 meters above the fleet is completely shrouded by a dome of strange rocks.

"The Star Wants To Retire"

This also shows that although the fleet has walked out of the narrow tunnel structure, it is still in a cavity deep in the earth's crust.

However, it was possible to get out of the narrow channel with turbulent undercurrents and raised rocks.

All in all, it is a rather gratifying news.

At the very least, the depressing feeling no longer hangs in my heart, and it makes my breathing a lot easier.

However, it didn't take long for everyone to be happy.

When the fleet followed the guidance of the sonar beacon, it showed an upward trend and floated for some distance.

The surrounding channel became narrow and congested again, and they entered another rock tunnel.

"I'm going, it's not over. How long does it take to get out of the ground?"

Meng Lei sighed helplessly, and his head became big.

In the end, he couldn't hold back the repression in his heart, so he called Hans over and asked:

"Hans, with a cave structure like this, how far do we have to go? Wouldn't it be like this all the way before reaching the hydrothermal wasteland?"

Hans shook his head and sighed helplessly:

"Captain, I'm not too sure about this road, because few people will go directly to the hydrothermal waste waters from Syr City. The outpost replenishes supplies and slowly explores the past."

After a pause, Hans added in a deep voice:

"The channel you choose should belong to the freight channel. Only supply ships at long-distance freight stations will choose to take this route in order to save time for detours and also because of energy consumption considerations.

So, the specific situation here, I am not particularly clear. "

Hearing this, Meng Lei was at a loss for words.

This is the loss of eating inexperienced.

Originally, he only wanted to be able to reach the sea area of ​​the hydrothermal wasteland as soon as possible, so he chose a relatively short route when he set off.

But I didn't realize it, and actually ran into the freight channel? !

This is similar to the difference between a highway and a national highway. Although the highway sometimes detours for a distance, it is farther than the national highway and provincial highway below.

However, the highway is easy to go!

Even though the national road is relatively close, it is bumpy.

If you have the kung fu to slow down, you might as well run for a while and go straight to high speed.

The key is that the highway is comfortable and the mood is good.

Meng Lei wanted to cry but had no tears, this is really inexplicable to find guilt for himself, to put it bluntly, or the preliminary planning work is not enough!

At this time, seeing Meng Lei's face a little ugly, Hans knew what he was thinking, so he added:

"Captain, don't take your breath away,

Although the environment of the cargo channel is complex, it is relatively difficult to travel, but other channels are not necessarily much easier than here.

I haven't been to the hydrothermal wasteland a lot, but the waterways I've traveled before are not too few, and the environment is similar.

Because the more you go deeper, the more complex the channel will increase, which is a very common phenomenon. "

Having said that, Hans paused for a while and said again:

"In addition, the hydrothermal waste area is a volcanic belt, with frequent geological movements,

The nearby cave environment is correspondingly more complex and changeable than other places, which is normal.

But since the alliance has chosen to designate this channel as a cargo channel,

In order to ensure the safety of the materials, it will not be too difficult to go ahead, and it should be able to pass for two more days. "

Hearing this, Meng Lei could only nod helplessly.

At this point, it is impossible to choose another way to return to the voyage, so I can only go on like this.

I only hope that as Hans said, it is best to pass through this complex sea as soon as possible.

No matter how bad it is, it can only be boiled slowly.

However, even though Meng Lei's mentality adjusted quickly, he slowly calmed down and continued to move forward with the fleet.

But the gods did not fulfill their wishes,

This voyage seems destined to experience many twists and turns, and it will not be so smooth.

Eleven o'clock at night.

Meng Lei had just brewed a cup of coffee, and was ready to hold on for a while longer.

But at this time, the navigation system was suddenly interrupted.

The connection signal with the next beacon site was lost inexplicably, and it could not be reconnected by any means.

Just like the last time around the outpost of Molten Rock, the beacon station appears to be malfunctioning.

This sudden change shocked Meng Lei.

Immediately stopped the fleet and stationed in place.

Hans and Karl came in a hurry, and even the two newly recruited A-level mechanical engineers rushed over from other ships in diving suits to check the signal receiver repeatedly.

It was finally determined that the problem was not on the Sea Locust, and the beacon station ahead must have failed.

"Captain, it's very late now. I suggest you take a short rest here for a night, and wait until you wake up tomorrow morning to see what's going on."

One of the two A-level mechanical engineers, a middle-aged man named Byron, made a suggestion.

"Normally, Alliance troubleshooting is four hours after the failure of the beacon station.

Because there are outposts near most beacon stations.

Generally, the fault will be maintained by the nearby outpost first. If the outpost cannot handle it, the alliance will issue a bounty task and send professional bounty hunters to deal with it.

But we are now in the cargo channel, and there are no outposts and gathering places nearby.

Once the signal is lost, the alliance will issue a bounty within an hour.

With any luck, the beacon station ahead should be repaired when we wake up tomorrow.

If we are unlucky, then we can take a rest first, wait until the state recovers tomorrow, and then check it out in person.

After all, no one knows what happened to that beacon station.

We'd better keep exploring at full capacity at all times, and don't approach it rashly. "

Hearing this, Meng Lei nodded in agreement, and immediately accepted Byron's suggestion.

At twelve o'clock in the evening, the fleet stopped in the dark and icy deep-sea rock formations, and stopped moving forward.

The five submarines turned off the external light sources and kept the sonar silent. Only the passive sonar continued to work~lightnovelpub.net~ The night duty personnel were arranged, and everyone returned to the crew room to sleep soundly.

Everyone slept badly that night.

Including Meng Lei.

In his sleep, there seemed to be something mixed in the rapids outside the ship, which had been gently rubbing the hull of the ship, making a terrifying scratching sound.

Also, there seems to be something moving at the top of the cabin.

From time to time, there will be a ding ding Dongdong sound, as if someone is playing a prank, gently hitting the hull shell with a hammer.

In the depths of the underground rock formations more than 3,000 meters deep in the deep sea, in the darkness of deathly silence.

Such a voice is undoubtedly full of reverie, and the scalp feels numb.

It's been a really tough night...
