Looking at this inscription, Lu Yuan's doubts not only did not decrease, but became more and more!

In order to clarify the doubts in his heart, Lu Yuan embarked on a journey again, this time to the Cook Islands.

The Cook Islands are a group of 15 islands located in the South Pacific Ocean between French Polynesia and Fiji.

Its name originates from Captain James Cook, who explored the South Pacific Ocean and discovered many islands.

Despite its small size, the Cook Islands are surrounded by two million square kilometres of economic water.

Therefore, fishery resources account for a very high proportion of the economy of the archipelago.

The overall economy of the Cook Islands is dominated by tourism, plantations, fisheries and offshore finance. Black pearl farming is also quite famous.

The reason why Lu Yuan chose this place is not because there is anything special about the Cook Islands.

The real reason he chose this place was simply that the sea depth was relatively shallow.

And according to the record on that map, the Cook Islands are also on the edge of the continent.

More importantly, according to the records, there has been no volcanic activity on the seabed around it for many years.

Perhaps some relics left over from the Mu Empire can be found in this area.

Of course, it would be better if you could find an underwater city.

However, Lu Yuan did not have much hope for this, because the Cook Islands area is also a very remote place in the Mu mainland.

At least all of the Seven Holy Cities are far away from here, and the area where the Seven Holy Cities are located is now 3,500 meters below the sea level.

Lu Yuan estimated that he was not able to practice qi above the sixth level, and he was not able to explore these areas at all.

Lu Yuan did not take modern transportation this time, but chose to escape directly from Guam to the Cook Islands.

On the way, he actually encountered the nuclear submarine of the Mi Army.

This is a Virginia-class nuclear submarine of the Mi Army, and it is also the number one nuclear submarine in the world today.

It is the first nuclear submarine of the U.S. Navy to be designed for both ocean and littoral functions, and is an extension of the NSSN program, and it is also a cheap alternative to the Seawolf-class submarines of the Cold War era.

In the bow of the boat there are 12 vertical launch tubes, which can launch the latest UGM-109E tactical Tomahawk missiles.

Equipped with four shoulder-fired 533.4 mm fish, it can fire MK48-ADCAB modl6/7 series wire-guided torpedoes, as well as MK60/67 self-propelled mines, with a total armament of 38 units.

On March 17, 2018, the 15th Virginia-class attack nuclear submarine, the USS Colorado, held a commissioning ceremony at the New London Naval Submarine Base in Connecticut.

Its water displacement has been unclear, while the announced submersible displacement is 7,800 tons, with a working depth of 240 meters and a maximum depth of 488 meters.

The total length is 114.91 meters, the total width is 10.36 meters, the maximum speed of sneaking is 34 knots, the self-sustaining power is about 70 days, and the crew is 134 people.

It can be said that it is a very powerful war machine, and it also poses a certain danger to Zhuxia.

When Lu Yuan saw this submarine, he naturally wouldn't miss it with him like this.

He hurriedly took out his specially customized underwater shooting equipment and tracked and filmed the submarine.

When he photographed the details of various parts of the submarine. Then he put away his camera equipment and continued on his way to the Cook Islands.

And the Mi Jun submarine, which was tracked and filmed for two full hours, still knows nothing about it.

About three hours after separating from the submarine, Lu Yuan discovered a strange place underwater.

It was an undersea rift, and the rift was neither big nor small.

According to Lu Yuan's judgment of water pressure, the water depth this time is about 1800-2000 meters.

On both sides of the rift valley, Lu Yuan found some traces of suspected human activity.

He excitedly swam to the edge of the rift to check it out. After some investigation, he judged that this was an ancient path.

The road is completely paved with stone slabs and has remained in the same condition it was in when it first sank to the bottom of the sea after countless years.

In order to find out where this road leads, Lu Yuan immediately followed this road to the east.

After walking for about 30 kilometers, Lu Yuan came to an undersea plain.

After a little further journey, we finally came to the end of the road.

At the end of the road is a pothole that is not known how deep.

It looks similar to the sea monster mine in the southeast of Yingzhou Island. It's just smaller.

"There's not going to be a sea monster hiding here!"

Lu Yuan looked at the pit with a wary expression.

"Probably not, there aren't many auras here!"

To ensure safety, he didn't enter the pit right away, but observed his surroundings and creatures first.

After careful observation and comparison, Lu Yuan found that there were more marine creatures here than in other places, and they were also larger than other places.

This discovery once again made Lu Yuan vigilant, and he tried to absorb the aura escaping from the pit.

It turned out that although there was not much aura here, it was quite pure and there were almost no impurities.

With this discovery, he breathed a sigh of relief.

"Looks like no one has ever used this pothole's aura. ”

Although he didn't feel the danger for the time being, Lu Yuan still pulled out the Wave Chaser Sword.

After checking the edge of the pit again, Lu Yuan entered the pit.

The further down he went, the more intense the aura became.

"This is a good place to cultivate!"

He continued to dive, and when he entered the pit for about 200 meters, he found a small glowing stone.

Lu Yuan walked over and picked it up.

The small stone bears a strong resemblance to the strange corpse he found inside the Kraken's pit.

There is also a special energy in the stone.

However, this stone contains a little more energy than the one I picked up before.

Lu Yuan put away the stones and searched around, but unfortunately he didn't find any other stones.

Lu Yuan continued to dive, and soon reached the bottom of the pit.

At the bottom of the pothole was something that resembled a truck.

After Lu Yuan found it, he was stunned at first, "How can there be a truck here?"

But he soon noticed that something was wrong.

Because the suspected truck was too large, it was at least 30 meters long, about 6 meters wide, and about 5 meters high.

Trucks of this size have never been made on the planet at all.

Lu Yuan cautiously approached the car, and after finding that there was no danger, he carefully checked it.

The car was cast from an alloy that Lu Yuan had never had before.

After soaking in the seawater, I don't know how many years have passed, and it is still as clean as new.

Although there are some kettle rattans on the body, there are not many of them, and they are not the same as those seen in other places.

Lu Yuan just touched it lightly, and the kettle vine fell off the body.

Lu Yuan tested the strength of the body, which was very strong and lightweight.

"This is a high-tech alloy!" Lu Yuan made a judgment in an instant.

"Who built this car?"

A doubt arose in Lu Yuan's heart.

This is obviously not something that can be made by modern civilization, not to mention anything else, and the material of the body cannot be made today.

At least not on a large scale.

In order to clarify this doubt, Lu Yuan carefully inspected the car.

He first took out his tools and removed all the sea creatures that covered the car.

"Wow, that's beautiful!"

When the car revealed his true face, Lu Yuan was immediately attracted to it.

He didn't expect the car to look so stunning as it was.

The appearance of a modern car is actually really ugly compared to it.

It was like admiring a work of art, admiring the car for a quarter of an hour.

Lu Yuan continued to explore the car.

He found some special text on the side and head of the car.

This kind of writing looks very weird, but it has a unique beauty.

However, this is also a kind of writing that has never been seen before, at least Lu Yuan has never seen this kind of writing before, whether it is in life or in various materials.

"Is this the script of that civilization, obviously not from the Mu Empire, nor from the Witch, is it the Atlantean script or the script of outsiders, or the Lemurian script?"

However, Lu Yuan quickly overturned the third speculation.

Because when he checked the information of the Lemuria continent again, he found that the poison country actually left some legendary Lemurian texts.

But the inherited Lemurian script is completely different from the writing on the body.

"Does this text belong to Atlantis or to outsiders?"

With this question, Lu Yuan continued to check.

After inspecting the exterior of the body, Lu Yuan came to the position of the car's power system.

Opening the protective cover outside, Lu Yuan was completely sure that the car did not belong to modern civilization.

Because he found that the power source of this car was actually the kind of energy spar in his hand.

Modern civilization uses mainly biomass and electrical energy, which is completely different from the energy used by this car.

Looking at the power system of this car, Lu Yuan didn't understand how he worked at all.

In desperation, he had to close the lid again, and then he went to the most important cockpit.

The cockpit is locked, but fortunately, Lu Yuan's control of spiritual power is quite good now.

Lu Yuan used his spiritual power to open the door of the cab.

The first thing that catches your eye is two skeletons, the clothes on which they are gone.

The skeletons were examined, and both skeletons had cracks in their skulls from the impact.

Lu Yuan speculated that the two men were driving the vehicle because of a sudden violent collision that resulted in death.

This can be seen from the location of the vehicle and the injuries on the deceased's body.

When Lu Yuan was examining the bones, he also found two nameplates on the corpses of the measuring tools.

The nameplate is hung around the neck and also has some text on it.

The text appears to be in the same language as the text on the car body.

After searching in the cab for a long time, Lu Yuan found two boxes, one large and one small.

He opened the big box first, and it contained exactly that kind of energy crystal.

And there is another small box, but this small box is relatively well locked, and Lu Yuan wasted a lot of effort to open it......
