Looking at the intricate and complex gravitational sphere in front of him, full of a sense of science and technology.

The corners of Meng Lei's mouth couldn't help but hook up a smile.

After working for most of the day, he also experienced a dangerous underwater fight.

In the end, this wasteland artifact was finally hammered out.

A great sense of accomplishment arose.

At this moment, Meng Lei felt that the crisis and dedication he had encountered before were all worth it.

In fact, the reason why the gravitational ball was repaired so quickly is thanks to the strange fish.

If it weren't for the strange fish, five units of large pieces of fish were harvested.

Relying on Meng Lei's own continuous launching, he exploited resources again and again.

The devil knows when we'll be able to get the materials we need to fix it.

The pay is directly proportional to the gain, and Meng Lei has a deep understanding of this at present.

In addition, through this incident, Meng Lei also became aware.

Goldfinger's evaluation of the trading market at the beginning was indeed not exaggerated.

If used properly, the trading system can indeed help players get through the wasteland period smoothly.

But the premise is that your own strength is hard enough!

You have to be able to come up with conditions that are attractive enough to attract the market in order to reap the corresponding benefits.

Otherwise, the result will be equally unclear and will not bring any change to itself!

"Now that the gravitational ball has been repaired, it's time to test the effect......

Holding a gravitational ball the size of a football in his hand, Meng Lei had a look of expectation on his face.

He put the gravitational ball back into the warehouse, then turned around and went back to the cockpit of the submarine.

It can be seen through the glass porthole directly ahead.

The Guiru's current location is still in a dark and desolate rock tunnel.

The three-dimensional topographic map presented on the sonar display also shows the current surrounding environment, which is not a vast sea area.

And there are countless large and small grottoes and caves all around.

Meng Lei also didn't know where those grottoes and caves led, so he didn't dare to venture in.

In addition, he did not know how the navigation route automatically planned by the submarine was set.

But it is clear that the sea he is in now is not suitable for fishing, it is too barren.

"Let's go forward first, we can't go the next 1,000 kilometers, and we have to drill holes along the way."

After a little groaning, Meng Lei was no longer entangled.

I found a comfortable position and sat crooked in the driver's seat of the submarine.

While enjoying the dull scenery outside the porthole, he let the submarine automatic navigation system drive all the way to the deeper part of the tunnel with the Guixu.

Fortunately, Meng Lei is not boring along the way.

Although the biological community in this undersea tunnel is relatively poor, the mineral resources are relatively rich.

On the sonar detection system, several anomalies will emerge from time to time.

Whenever he found an anomaly with great mining value, Meng Lei would not hesitate to go into the water and take it into his pocket.

However, after having previous experiences.

Meng Lei didn't dare to go into those unknown caves, he went too deep.

The last time he inexplicably encountered a strange fish, he was lucky.

God knows what strange things will come out of the way next time.

You must know that the xenomorph anglerfish is just an ordinary fish in the deep sea, and it can already pose a great threat to him.

If he encounters a serious alien sea monster, I'm afraid he won't even have a chance to fight back, and he will be killed on the spot!

Therefore, most of the anomalies that Meng Lei chose for his next voyage were near the entrance of the cave.

Even if you encounter danger, you can get out as soon as possible and return to the submarine.

Along the way, fortunately, there was no crisis.

During this period, the golden finger, which can give hints to all abnormal points, played a great role!

In fact, this deep and endless undersea tunnel is not as calm as it seems on the surface.

There are indeed a lot of threats lurking in those marine cave structures that extend in all directions.

There are a variety of different types of alien sea monsters lurking.

Just the monsters that don't have the same name, Meng Lei has already seen four kinds.

Among them are deep-sea worms, mud algae crawlers, pointy sharks, needleworms.

I don't know what these guys look like, but as you can tell from the name, they're definitely scary and difficult guys!

Without Goldfinger's reminder, they ventured into their territory.

The consequences are unimaginable!

And as he continued to go deeper, there were more and more sea monsters marked on the anomaly, which also made Meng Lei feel an invisible pressure.

Now that you don't have to worry about eating and drinking, the main goal of the next step is first to make out the ship-borne batteries.

At all times, having a gun in hand is reassuring.

Also, the omnipresent threat aside.

The harvest of this trip is quite expensive.

Over a distance of nearly ten kilometers, he mined a total of 20 units of iron ore and 18 units of copper ore.

Tin ore and aluminum, also have ten units each.

However, it is a pity that in the past hour or so, there have been no more materials like storage boxes.

There are very few plant resources with collection value.

There are only five units of plant fiber that can be broken down.

There isn't even one edible fiber!

This inevitably made Meng Lei feel a little doubtful about whether the most basic survival material energy bar had manufacturing value.

The synthesis list of the manufacturing table clearly indicates that five parts of edible fiber are required to make an energy bar.

Also, 100ml of fresh water is required.

It is so difficult to obtain edible fiber alone, and you have to take another 100ml of fresh water.

In this way, it is better to catch fish and eat it.

However, this question does not mean much to Meng Lei.

Now he wants to eat and drink.

The most basic survival guarantee has been satisfied, and to consider those problems is purely groundless.

Now he is most concerned about the issue of shipborne weapons.

So far, the resources he has on hand are quite abundant.

However, there is still a huge gap between the creation of shipborne weapons.

The key is that carbon ore, one of the main materials for making steel bars.

From the time of crossing to the present, he has not even seen one.

Without carbon, you can't make steel bar.

You can't make steel bars, upgrade submarine structures, build shipboard weapons, everything is empty talk.

"It seems that if you want to obtain carbon ore in large quantities, you have to start from the trading market, the randomness of resource distribution is too strong, and with my own strength, I can get together the materials for the electromagnetic cannon in the Year of the Monkey!"

"We have to find a place as soon as possible and throw a few nets of fish to the market!"

Just as Meng Lei was thinking.

The three-dimensional virtual map of the sonar display suddenly changed.

This narrow undersea tunnel seems to have come to an end.

Hundreds of meters ahead, a huge space that could not be detected appeared, like another world, extremely vast!

Meng Lei's heart perked.

"Is it finally out?!"
