When Lu Yuan arrived at the bottom of the sea, he found that the depth of the ocean here was about 1,800 meters.

This depth is naturally no pressure on Lu Yuan.

After playing with the fish at the bottom of the sea, he began to explore his surroundings.

The place where Lu Yuan arrived was a valley under the sea, where the terrain was relatively flat, which was quite different from the South Pacific region.

However, the overall environment is very normal, and no energy anomalies have been noted.

The various creatures are also ordinary. Lu Yuan searched for a long time, and he didn't even see the shadow of a large sea creature.

Lu Yuan didn't find anything unusual, and simply regarded this trip to the bottom of the sea as a tour.

Not to mention, the scenery under the sea is still different from that on land.

There are also mountains, plains, and canyons at the bottom of the sea, and there are also water currents.

In particular, the water flows can be regarded as rivers on land.

At a depth of 1,800 meters, although there are relatively few marine plants, there are still many other species and quantities of organisms.

In Lu Yuan's view, the colors here are even more vivid than on land, and the biodiversity is stronger.

After a while, Lu Yuan walked out of the valley and entered an undersea plain.

Walking and walking far away, I gradually realized that something was wrong, and it was too peaceful here.

In order to get a clear view of this submarine plain, Lu Yuan climbed a nearby submarine mountain range.

Looking down from the top of the mountain range, the scene in front of him made Lu Yuan feel very surprised.

The submarine plain at the foot of the mountain has clearly been artificially modified.

The piece in the middle of the plain looks like an airport runway, but the runways are very wide.

If this is really a runway, it's hard to imagine how huge this plane would be.

"This can't be a runway for a starship!"

Lu Yuan muttered secretly.

He wanted to gauge the size of the area, but it was too big for one person to do such a huge task.

So after only about 2 hours, he gave up.

After returning to the cruise ship, Lu Yuan simply notified the Joint Research Institute.

When the Joint Research Institute learned the news, it attached great importance to it. It was immediately reported to the respective countries.

The next day, the nearest ship came to the nearby seas.

"Mr. Brown, I didn't expect to see you again, aren't you a diplomat, why did you suddenly become a soldier?"

"Haha, I was originally a soldier, but I was a military attache at the time!"

"I see, Mr. Brown, it's so much more handsome in a military uniform than in a formal dress!"

"Mr. Lu said with a smile, I still prefer to wear a dress, I have always been a pacifist. ”

Lu Yuan secretly cursed in his heart, "Hypocrisy!"

"I didn't expect there to be pacifists in your navy......"

"Of course ......"

"Let's not talk about this for now, Mr. Lu has found something good this time. ”

"We rushed over as soon as we got the news. ”

"It's nothing, it's just that we found a small airfield at the bottom of the sea under our feet. ”

"Small airport! Mr. Lu said that he found an airfield on the bottom of the sea. ”

"Of course, the purpose of this notification to the Joint Research Institute is to measure and thoroughly investigate this small airport!"

"Mr. Lu Yuan, you can rest for a while......

"You're busy!"

After Lu Yuan returned to his yacht, he opened a bottle of red wine and tasted it alone.

Brown led the sailors to get busy.

"Oh, Shet, the water here is at least 1,800 meters deep, we can't measure it!"

"William, contact the headquarters and ask them to send a special survey ship. ”

"Lyle, notify the nearby warships, block the nearby seas, and no ships are allowed to approach except for the ships of the Joint Research Institute!"

"Your Excellency, do Costa Rican ships need to be expelled?"

"Of course, I heard it clearly, all the ships except the Joint Research Institute!"

After this order was issued, the Mi warships that arrived later quickly launched an operation.

All the ships in the surrounding waters were brutally driven away.

Lu Yuan has been very comfortable these days, and he fishes alone during the day.

In the evening, I went to the boat of the rice people to participate in the drinking party.

Four days later, two large research ships arrived in the area with a large number of technicians and some media reporters.

After some measurements by professionals, the underwater structure found by Lu Yuan is indeed similar to the airport runway.

But it's much bigger than an airport!

Its criss-crossed buildings are 150 kilometers long and 8 kilometers wide.

After examination by scientists, the structures were indeed man-made.

The material they used was a new material that had never been seen before, and it was not the same as the one used in the capital of the Kara Empire.

The strength and heat resistance of this building material are far greater than those of all known materials.

Scientists believe that if the technology for the production of this material can be mastered, the level of science and technology on the planet will also be greatly improved.

In light of this, the scientists applied for an additional project under the joint institute. This project is dedicated to the construction materials of these runways.

After the application was sent, it was quickly approved by various countries and the corresponding funds were sown.

The reporters who came with the research ship also made a series of reports on the building.

"Mr. Lu Yuan, a world-famous explorer, recently discovered a huge underwater structure in the sea area about 80 kilometers northeast of Cocos Island in the eastern Pacific Ocean!

The structure consists of several criss-crossing runways, which have been confirmed by the scientific community to be artificially constructed.

It is reported that the length of these runways reaches 150 kilometers and the width reaches 8 kilometers. Theoretically enough space for a starship to land and take off to a nearby galaxy!

This huge underwater structure is located at a depth of 1,800 meters, and the excavation of this site once again proves the existence of the prehistoric civilization and the high development of its civilization!"

As soon as this report came out, it once again attracted the attention of the scientific and historical circles, but ordinary people did not care much about it.

After this incident was over, Lu Yuan did not return to Yingzhou, but sailed back to San Jose alone.

After retiring the chartered boat, Lu Yuan left San Jose and headed for the pristine forest to the east.

After entering the forest, Lu Yuan did not go deeper, but returned to San Jose again without realizing it.

His real target this time is Cocos Island.

The last time Cocos Island administrators refused to let him land on the island, he was only interested in Cocos Island.

Lu Yuan now also wanted to see what the legendary pirate treasure was like when it arrived.

Lu Yuan waited until the dead of night before he quietly went to the sea and dived to Cocos Island......
