Deep Sea Survival: Start a Submarine

A faint blue halo dissipated before his eyes.

With the falling of the system prompt, the overall structure of the Guixu number has changed a little bit from before.

Meng Lei stood in the living cabin and looked around.

Although through the appearance of the interior, it is not obvious that there has been much change on the surface.

But he could vaguely feel that the structural layer erection between the outer shell and the inner wall seemed to be more sophisticated than before.

Meng Lei took a deep breath, a smile on his face.

Don't look at the distance of 300 meters, which is not a lot. It takes less than a minute to run on land.

But if it is replaced by a vertical drop, it is a hundred floors tall!

Such a large span is enough for Guixu to dive into some small abyss.

However, this level of improvement has still not reached the ideal value expected by Meng Lei.

Nowadays, there are still a lot of materials hoarded in the warehouse, and keeping them also takes up space.

Meng Lei's principle is to make the best use of everything.

The most important thing is to use everything you can use to strengthen yourself.

therefore.

Meng Lei continued to focus on the submarine structure, and carried out two consecutive upgrades.

It was not until the compressive limit of Guixu was raised to a depth of 3,200 meters that it gave up.

"The water depth of 3,200 meters increases the compressive upper limit of 700 meters compared to the initial structure."

"The ultimate pressure of this level should be enough for me to dive down a long distance."

All of a sudden, the ultimate compressive capacity of 700 meters has been increased, which is equivalent to the average depth of Blue Star's largest freshwater lake.

Meng Lei felt that at least until he arrived at Gathering No. 1, he should not have to make any modifications to the submarine structure.

You know, the transformation of the submarine structure is quite resource-intensive.

The structural transformation of the submarine that directly spanned three levels consumed a third of the reserves in his warehouse!

The resources of nearly 200 units are gone.

If this is left on other players, I am afraid that even if you work hard for three days, you may not be able to accumulate such a huge resource reserve.

Therefore, Meng Lei judged that the depth of the sea area where the No. 1 gathering place is located should be about 3,000 meters, and it will not be deeper.

if not.

Among these 100,000 people, one percent will eventually arrive on time, that is, burning high incense!

"Next, it's the turn of the sonar detection system..."

Click the upgrade button on the transformation table again.

The transformation of the sonar detection system does not require the use of synthetic materials such as steel bars.

Only the most basic resources such as iron, copper and carbon are needed.

Therefore, the moment Meng Lei touched the screen with his finger.

The corresponding resources were instantly extracted, and then, a light blue halo flashed again in the cockpit.

When Meng Lei opened the cockpit door, the upgrade of the sonar detection system was over.

In front of you is a sonar display that looks more sophisticated than before.

In addition, the three-dimensional virtual map projected on the side of the driver's seat has doubled the retraction ratio than before!

[System Tip: Congratulations on completing a sonar detection system transformation, the detection range has been enhanced to a certain extent, and the current sonar transmission limit is 1000 meters! 】

Take a look at the upgrade options for the sonar detection system.

Even if the sonar system is upgraded to the top level, there are only three levels.

At the moment, Meng Lei upgraded the sonar system to the full level without hesitation.

This time, it didn't cost too much material in total.

And the upgrade options on the transformation table finally showed a completely different change from the previous one for the first time.

[Primary sonar system (3/3), cannot be upgraded further, more powerful sonar detectors need corresponding blueprints to unlock! The current sonar transmission limit is 2000 meters! 】

Staring at the system prompt given by the transformation interface, Meng Lei stroked his chin thoughtfully.

This is not the first time he has heard of blueprints.

However, as of now, he has not seen any player who has salvaged the blueprint at this stage.

At the very least, no one mentioned it in the communication channel.

In the trading market and auction house, no one has posted the source of blueprints.

It can be seen that various equipment and transformation blueprints should not be accessible to players at this stage.

Or, someone got some kind of blueprint, but deliberately kept it hidden from the public.

Or you want to keep it for yourself.

Or wait until most people have passed the difficult period of land reclamation and have a little more money on their hands, and then sell them for a good price.

Meng Lei didn't care too much about this.

He has always been in a good mood.

A cherished item like a blueprint is something that cannot be found.

If you have the opportunity, you can take it into your pocket and strengthen yourself, and naturally you can't let it go easily.

If you really don't have that fate, you can't force it.

Anyway, at this stage, he is far ahead of everyone.

The point is, he still has golden fingers!

During the voyage, the chances of discovering hidden treasures are much greater than anyone else.

This concern, of course, does not exist.

After completing the upgrade of the sonar detection system, the last step is the submarine shell.

It was also upgraded twice in a row, and the submarine hull was reinforced.

The more than 600 units of resources just harvested have shrunk sharply by more than two-thirds!

I have to say that upgrading and transforming submarines is really a huge project!

In the end, it was not that Meng Lei was reluctant to continue to waste it, but that the reserves of titanium ore could no longer meet the needs of the third transformation.

As a last resort, Meng Lei could only give up temporarily.

After this transformation, UU Reading www. The overall evaluation of the uukanshu.com Guixu account has been upgraded from H to H+.

Although the evaluation level has not changed, the addition of a plus sign makes people feel taller.

It is estimated that after Meng Lei upgrades all the columns in the transformation list to full level, the evaluation level will reach G level.

But none of that matters anymore.

With the current capabilities of the Guixu, as long as Meng Lei does not kill himself, there should not be too much danger in the shallow waters.

With a long breath, Meng Lei crossed Erlang's legs and lay crooked on the simple air mattress in the living cabin.

Beautifully looking around, his eyes swept over the fresh water extractor and the electromagnetic cannon loader, and he looked at the results of his current efforts with satisfaction.

A great sense of achievement came spontaneously, and he was looking forward to the next deep dive.

At this time, I don't know if it was because I drank too much water just now.

Suddenly, the urge to urinate hit, and Meng Lei shuddered.

He turned over with a harrier and bounced off the air mattress, looking around in horror.

In the end, Meng Lei suddenly discovered an extremely frightening problem!

"Fuck, there doesn't seem to be a toilet in this submarine?!"

From the beginning of the game to the present, all his energy has been focused on how to survive, and he has never felt any desire to excrete!

Now that he finally relaxed, he finally realized the problem.

But after searching all over the cockpit and living cabin, he found desperately that this game did not prepare excretory facilities for players!

This **** is a little scary!

With his legs clamped in place and scratching his head, Meng Lei struggled for a long time, and finally turned his attention to the closed airlock door.

"or…"
