Going Deeper!

He looked at the complicated and technologically advanced gravity ball in front of him.

Meng Lei could not help but smile.

After being busy for half a day, and even experiencing a dangerous underwater battle, in the end, he finally created this divine exploration tool.

A huge sense of accomplishment arose spontaneously.

At this moment, Meng Lei felt that the danger and sacrifice he had encountered earlier were all worth it.

In fact, the reason why the gravity ball could be repaired so quickly was all thanks to that strange fish.

If not for the fact that he had obtained five units of large fish meat from that strange fish, just relying on Meng Lei diving repeatedly into the water to personally mine resources, one would not know when he would be able to gather all the necessary materials for the repair.

The rewards were proportional to the effort. At this moment, Meng Lei deeply realized this point.

In addition, Meng Lei also realized through this matter that the game cheat's evaluation of the trading market back then was indeed not exaggerated.

If used properly, the trading system could indeed help players successfully get through the exploration period.

However, the prerequisite was that he had to be strong enough!

You have to be able to offer enough conditions to attract the market to obtain the corresponding benefits.

Otherwise, the end result would be the same. It would not bring any change to him!

"Since the gravity ball has been repaired, the next step is to test the effect…"

Holding the football-sized gravity ball in his hand, Meng Lei looked expectant.

He first put the gravity ball back into the storage chest, then turned around and returned to the submarine's cockpit.

It could be seen through the glass porthole directly ahead that

Bottomless Valley was still in a dark and desolate rock tunnel.

The three-dimensional topographical map displayed on the sonar display also showed the current environment, which was not quite a vast sea.

There were countless grottos and caves of various sizes all around.

Meng Lei was not sure where those caves led to, so he did not dare to venture into them.

Moreover, he did not know how the submarine's auto-navigation route was set.

However, it was obvious that the sea area he was in was definitely not suitable for fishing. It was too barren.

"It's better to go forward first. I can't be drilling holes all the way in the next thousand kilometers."

After pondering for a moment, Meng Lei no longer hesitated.

He found a comfortable position and sat in the pilot seat.

While admiring the silent and dull scenery outside the porthole, he allowed the submarine's auto-navigation system to take Bottomless Valley deeper into the tunnel.

Fortunately, Meng Lei was not bored along the way.

Although the biological ecosystem in this underwater tunnel was relatively barren, the mineral resources were abundant.

From time to time, a few anomalies would appear on the sonar detection system.

Every time Meng Lei discovered an anomaly that was of great value for mining, he would enter the water without hesitation and take it for himself.

However, after his previous experience, Meng Lei did not dare to go too deep into those unknown caves.

The last time he encountered a strange fish for no reason, he was lucky.

Only God would know what strange things would appear next time.

The mutated carp was just an ordinary fish in the deep sea, but it was already a huge threat to him.

If he were to encounter a real alien planet sea monster, he would probably be killed on the spot without even having the chance to fight back!

Therefore, the anomalies that Meng Lei chose for the rest of the voyage were mostly near the entrance of a cave.

Even if he encountered danger, he could escape as soon as possible and return to the submarine.

Fortunately, there was no danger along the way.

During this period, the game cheat that could provide hints to all anomalies played a huge role!

In fact, this deep and endless underwater tunnel was not as calm as it seemed.

There were indeed a large number of threats lurking in the structure of the ocean caves that led to all directions.

There were all kinds of alien sea monsters lurking around.

Meng Lei had already seen four kinds of monsters of different names.

Among them were deep-sea worms, algae crawlers, sharp-tailed sharks, and needleworms.

Although he did not know what these guys looked like, he could tell from their names that they were definitely terrifying and difficult to deal with!

If not for the game cheat's alerts, he would have barged into their territory.

The consequences would have been unimaginable!

As he continued to go deeper, more and more sea monsters were marked on the anomalies, making Meng Lei feel an invisible pressure.

Now that he did not have to worry about food and drink, the next main goal was to produce a shipborne gun turret.

No matter what, having a gun in hand would make one feel at ease.

In addition, putting aside the omnipresent threat, the gains from this trip were quite considerable.

On the ten-kilometer journey, he had mined a total of twenty units of iron and eighteen units of copper.

He also had obtained ten units each of tin and aluminum.

However, it was a pity that he did not encounter anything like storage boxes in the past hour.

There were also very few plant resources of harvesting value.

There were only five units of plant fiber that could be decomposed.

There was not even a single edible fiber!

Meng Lei could not help but wonder if the most basic supply for survival, the energy bar, had any manufacturing value.

The production list of the manufacturing station clearly indicated that five portions of edible fibers were needed to make an energy bar.

Moreover, 100ml of fresh water was needed.

It was already so difficult to obtain edible fibers alone. He had to add another 100 ml of fresh water.

In that case, he might as well catch fish and eat them.

However, this problem was not significant to Meng Lei.

Now he had food and drink.

The most basic guarantee of survival had already been met. It was purely unnecessary to worry about those problems.

What he was most concerned about now was the issue of shipborne weapons.

So far, the resources he had were quite abundant.

However, there was still a huge gap from building a shipborne weapon.

The key was carbon ore, which was one of the main materials for making steel bars.

Ever since he transmigrated, he had not even seen one.

Without carbon, steel bars could not be made.

If he could not make steel bars, upgrading the submarine structure, and building shipboard weapons would all be empty talk.

"It seems that if I want to obtain carbon in large quantities, I have to start from the trading market. The random distribution of resources is too great. It will take me years to gather the materials for the electromagnetic cannon alone!"

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

Just as Meng Lei was pondering…

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

The long underwater tunnel seemed to have come to an end.

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

Meng Lei's mind shook.

"Finally, I'm out?!"
