Looking at the complete gravitational ball in front of me that is sophisticated and full of technology.

The corner of Meng Lei's mouth couldn't help but evoke a smile.

After being busy for a long time, I also experienced a dangerous underwater fight.

In the end, this wasteland artifact was finally fiddled with.

A great sense of accomplishment came over me.

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

In fact, the reason why the gravitational ball can be repaired so quickly is thanks to that strange fish in the end.

If it weren't for that strange fish, five units of chunks of fish were harvested.

Just relying on Meng Lei's own continuous launching, he exploited resources again and again by himself.

The devil knows when the materials needed for the repair will be cobbled together.

Efforts and gains are directly proportional, and Meng Lei now deeply realizes this.

In addition, Meng Lei realized through this incident.

Goldfinger's evaluation of the trading market at the beginning did not exaggerate.

If used properly, the trading system can indeed help players to go 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 enough conditions to attract the market, in order to obtain the corresponding benefits.

Otherwise, the result will be the same, and it will not bring any changes to itself!

"Since the gravitational ball has been repaired, then the next step is to test the effect..."

Holding a football-sized gravitational ball in his hand, a look of anticipation appeared on Meng Lei's face.

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

It can be seen through the glass porthole directly ahead.

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

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

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

Meng Lei didn't know where those grottoes and caves were leading, so he didn't dare to break in.

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

But obviously the sea area where he is now is not suitable for fishing, it is too barren.

"It's better to walk forward first. You can't always drill holes along the way for the next thousand kilometers."

After pondering for a while, Meng Lei no longer struggled.

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

While watching the dull and tasteless scenery outside the porthole, let the automatic navigation system of the submarine drive the Guixu all the way to the deeper part of the tunnel.

Fortunately, Meng Lei was not boring along the way.

Although the biological community in this underwater tunnel is relatively barren, the mineral resources are relatively rich.

On the sonar detection system, several abnormal points will appear from time to time.

Whenever an abnormal point of great mining value is discovered, Meng Lei will go into the water without hesitation and take it into his pocket.

However, after having the previous experience.

Meng Lei did not dare to go too deep into those unknown caves.

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

God knows what strange things will come out next time.

You must know that the xenophobia 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 am afraid that he will not even have a chance to fight back, and he will be killed on the spot!

Therefore, in the next voyage Meng Lei chose, most of the abnormal points were near the entrance of the cave.

Even if they are in danger, they can escape as soon as possible and return to the submarine.

Along the way, fortunately, there is no crisis.

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

In fact, this deep and endless underwater tunnel is not as peaceful as it looks on the surface.

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

There are various types of alien krakens dormant.

Meng Lei has already seen four kinds of monsters with different names.

Among them are deep sea worms, mud algae creepers, sharp sharks, needle worms.

Although I don't know what these guys look like, I can tell from their names that they are definitely some terrifying and difficult guys!

If there is no reminder from Goldfinger, they have ventured into their territory.

The consequences are simply unimaginable!

With the continuous deepening, more and more sea monsters were marked on the abnormal points, 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 to fiddle with the ship-borne battery.

At all times, having a gun in your hand is the only way to feel at ease.

Plus, put aside the omnipresent threat.

The harvest of this trip is quite a lot.

For a distance of nearly ten kilometers, he mined a total of twenty units of iron ore and eighteen units of copper ore.

Tin ore and aluminum ore, also have ten units each.

However, it is a pity that in this more than an hour, I have not encountered such materials as storage boxes again.

And there are very few plant resources with collection value.

The plant fiber that can be decomposed is only five units.

Not even a single edible fiber!

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

The crafting table's synthesis list is clearly marked. UU reading www.uukanshu.com requires five servings of edible fiber to make an energy bar.

Also, 100ml of fresh water is required.

It is so difficult to obtain edible fiber, and 100ml of fresh water has to be added.

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

However, this question is of little significance to Meng Lei.

Now he wants to eat and eat and drink and drink.

The most basic survival guarantee has been met, and it is purely unfounded to think about those issues.

Now he is most concerned about the issue of ship-borne weapons.

As of now, the resource reserves he has on hand are quite rich.

There is still a huge gap in the distance to build shipborne weapons.

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

He hasn't even seen a single one since he crossed over to the present.

Without carbon, steel can't be made.

Can't make steel bars, upgrade submarine structure, build ship-borne 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. With my own strength, the year of the monkey and the horse month can collect the materials for the electromagnetic gun!"

"You have to find a place as soon as possible and throw a few nets on the market!"

Just as Meng Lei was thinking.

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

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

Hundreds of meters in front, there is a huge space that cannot be detected, just like the other world, it is extremely vast!

Meng Lei was refreshed.

"Finally out?!"
