After Lu Yuan relieved the ecstasy of Silem, he hypnotized Silem again.

He then left the cave and headed in the direction of the Eye of the Sahara.

The Eye of the Sahara, which was previously considered by scholars to be a huge prehistoric city.

Some scholars even speculate that the Eye of the Sahara is even the mysterious continent of Atlantis, based on its appearance.

However, for some incomprehensible reason, scholars have never been able to find the true location of the Eye of the Sahara, which has stalled research.

Lu Yuan certainly wouldn't think that the Eye of the Sahara would be Atlantis.

Earlier maps have told Lu Yuan that the continent of Atlantis is in the Atlantic Ocean, and that it sank 12,000 years ago.

However, although the Eye of the Sahara is not Atlantis, it certainly has a very important connection to Atlantis.

Lu Yuan is now also full of curiosity about the ancient city under the eyes of the Sahara.

On his way to the Eye of the Sahara, he even speculated if the destruction of the ancient city was the work of the aliens in the base.

When Lu Yuan arrived at the periphery of the Eye of the Sahara, Silem also woke up leisurely.

Although he no longer remembered how he was in a coma and was interrogated by Lu Yuan, he still found out that something was wrong.

Silem had been wrestling with whether or not to report the incident.

However, he also knew in his heart that as long as he reported this matter, his future would be ruined.

After a difficult struggle in his heart, he finally chose to hide the incident.

After making his decision, he slowly walked out of the cave and returned to the oasis.

When Lu Yuan arrived at the Eye of the Sahara, there were already many outsiders around.

Judging from the outfit, there were people from several surrounding countries, and Lu Yuan even saw a few yellow people, and it seemed that the news of the ancient city had been completely spread.

However, this is also normal, although people were unable to enter the Eye of the Sahara because of the Oasis base.

But it's still possible for satellites to observe it from space.

The Jews did not deliberately conceal the excavation of the ancient city, and it was obviously impossible to evade the detection of satellites.

After some observation, Lu Yuan found that although there were many people near the Eye of the Sahara, there had been no formal excavation of the ancient city.

Now these people are mainly interested in protecting the ancient city.

Their main purpose was to prevent others from entering the confines of the ancient city and waiting for the arrival of the international expedition.

This made Lu Yuan very happy, and he decided to take advantage of the time before the international scientific expedition team arrived, to explore the ancient city first.

Just do what he said, Lu Yuan didn't rest, and entered the ancient city directly from the underground.

The ancient city was a little smaller than Lu Yuan had previously thought, and it was also much more dilapidated than expected.

Lu Yuan found a lot of glass-like items in the ancient city.

Obviously, the ancient city once experienced extremely high temperatures.

These glass-like items can only be produced at high temperatures.

Lu Yuan's first thought was a nuclear explosion. In Lu Yuan's view, the consequences of a nuclear explosion are most consistent with the current situation.

However, Lu Yuan could not confirm whether it was a nuclear explosion. Because if it were a nuclear explosion, this ancient city would have been completely wiped out.

But now, although the ancient city is dilapidated, it still exists.

Again, this is not quite the same as the consequences of a nuclear explosion.

Lu Yuan was puzzled, quietly searching in the ruins of the ancient city.

After some searching on the periphery, he found nothing.

At this time, he plans to enter the core area, and maybe he can gain something in the core area.

After entering the core area, Lu Yuan found that the buildings here were obviously more magnificent than those on the periphery.

Although the original appearance of the ancient city can no longer be seen, just the foundation that has been preserved can tell how huge these buildings were originally.

After two days of exploration, Lu Yuan was pleasantly surprised to find that this ancient city was actually a three-story concentric circle structure.

Such an urban structure is very, very special.

In all accounts, only Atlantean cities were built in this way.

"Is this really the city of Atlanteans!"

Lu Yuan resisted the excitement in his heart and continued to search.

Unfortunately, the ancient city was so badly destroyed that he came out and found a few half-melted orichalcum coins, but there was nothing else to gain.

Lu Yuan believes that there must still be a lot of good things left in this ancient city.

However, in order to prevent being discovered, he did not dare to act arbitrarily, which led to many places where he could not go.

Lu Yuan stopped temporarily at this time, and he also found that his aimless collection was too inefficient.

He recalled the city profiles of the Atlanteans he had seen before.

According to records, the Atlanteans would build a pyramid in the center of the city.

Some of the most important things in the city are kept inside the pyramids.

After thinking of this, Lu Yuan decided to give up searching for other places and go directly to the pyramids.

After all, the international scientific expedition team will be coming soon, and Lu Yuan must leave before these people arrive.

Otherwise, under the high-tech detection equipment, although he is lurking underground, he will be discovered.

Lu Yuan quickly found the location of the pyramid.

Like the rest of the ancient city, the pyramid has been completely destroyed, leaving only a small part buried in the ground.

Looking at the pyramid wreckage in front of him, Lu Yuan felt that his heart had become cold.

In such a situation, it is not easy to find something useful for yourself.

Lu Yuan sighed, but still started to look for it underground.

In this process, Lu Yuan still found some things, but unfortunately, they were all melted by the high temperature just like the mountain copper coins found before.

With a disappointed mood, Lu Yuan continued to look for a match.

At this time, what supported him to continue looking for it was only the unwillingness in his heart.

"Huh!"

Just as Lu Yuan was about to give up, his divine sense suddenly found a square metal object.

The object is buried 100 meters underground.

Lu Yuan quickly sneaked towards the target, and soon he was in front of the object.

What appeared in front of him was a rectangular metal plate.

The metal plate is relatively thin and does not weigh much.

What excites Lu Yuan the most is that this metal plate does not show any signs of melting at high temperatures.

Lu Yuan quickly cleaned up the metal plate, and at this time, a very beautifully drawn map appeared on the metal plate.

Lu Yuan smiled and put away the metal plate. Then he gave up the search and left the Eye of the Sahara.

Less than an hour after Lu Yuan left the Eye of the Sahara, a large number of scientific researchers entered the Eye of the Sahara under the protection of armed men.

The next day, international organizations announced to the world the discovery of the prehistoric Sahara.
