Lu Yuan descended from the roof of the cave to the ground and continued to search the vicinity.

All of this is just his speculation, and more physical evidence is needed to prove whether the speculation is true.

There were only five people on the Nazi expedition, and even if they found a flying saucer, they would not be able to carry it away.

If there is a flying saucer here, it must still be in the cave.

Lu Yuan's goal now is to find out this flying saucer.

Lu Yuan slowly searched in the cave, and soon he found a gate in the deepest part of the cave.

The gate is made of an alloy material.

Aside from the fact that it has been covered by the surrounding vegetation due to the passage of time, the gate itself has not changed much.

When Lu Yuan cleaned up the surrounding plants, the gate that appeared in front of him still looked as clean as new, and it was full of a sense of technology.

Lu Yuan tried to open the door, but he didn't fail.

The gate was stronger than he had imagined.

Lu Yuan sensed through his divine sense that this gate was controlled by a password.

To open this gate, you need to first crack its code.

In the job of cracking the code, Lu Yuan is completely "seven tricks through six tricks, not one clue!"

However, Lu Yuan still has a way to cheat, and his divine sense and mana can help him cheat.

Even with the help of his divine sense, it took Lu Yuan a full half an hour to open the door.

When he opened the door, what appeared in front of Lu Yuan was a science fiction world.

The things here are too high-tech, and Lu Yuan was completely shocked.

However, he was disappointed that the energy in the base had been depleted due to its age.

With the exception of a very few facilities, the rest of the equipment stopped working due to lack of energy.

Lu Yuan was like Grandma Liu who entered the Grand View Garden, and she was dazzled for a while.

He couldn't wait to move everything here back home.

Lu Yuan believed that if the human race mastered the technology of this base, it would soon become a new interstellar civilization.

Lu Yuan was about to dismantle the various equipment he saw when he suddenly noticed that something was wrong.

If I dismantle these things and transport them back to Yingzhou, I am afraid that not only will not bring benefits to Yingzhou, but will bring huge disasters to Yingzhou.

"As the so-called children hold money in the downtown area, if they really do this, they are simply looking for death!"

"If you dismantle these things and donate them to Zhuxia, it will be a troublesome thing to agree. ”

"It's impossible to hide such an important matter from the spies of other countries!"

After weighing it repeatedly, Lu Yuan gave up his original plan, and he planned to notify Zhu Xia directly after the exploration was completed, which would be the safest.

Even if the outside world discovers this base one day, the only real threat to this place is physical poison.

If the poison man launched an attack on Zhu Xia, Lu Yuan would naturally cooperate with Zhu Xia to make the poison man suffer a big loss.

Lu Yuan is not a virgin, he always remembers the assassination of himself by a poisonous person.

If the poisoner really troubles Zhuxia, he can also take the opportunity to take revenge on the poisoner.

However, Lu Yuan understood that although Ah San liked to brag, he was not stupid! It was impossible to easily provoke a war against Zhu Xia.

As long as a large-scale war broke out, the place was still very safe.

Although the big powers other than poison are stronger, Lu Yuan is not worried about their threat.

First, the strength of Zhuxia is not weak, and secondly, this place is located on the roof of the world.

It is very difficult to start a war operation here.

What's more, this place is so hidden, and secret research is carried out here, if there is no information sold by their own people.

Even if it takes a decade or two for foreign powers to figure out what exactly is going on here.

After a decade or two, even if it is discovered, there is no big problem.

Lu Yuan believed that with the ability of Zhuxia scientists, he would definitely be able to research a lot of high-tech things in one or two decades.

At that time, Zhuxia's scientific and technological strength can completely crush other countries.

With the support of high-tech weapons, coupled with Zhu Xia's huge manpower and material resources.

Lu Yuan believed that there would be no country that would be able to compete with Zhu Xia at that time.

However, before handing over this base to Zhu Xia, Lu Yuan still had to explore it carefully.

After handing over this base, I'm afraid I won't be qualified to enter.

Lu Yuan slowly visited the base, and after making plans, he was now calm.

Anyway, this base is here, and the things inside can't escape.

It took three days for Lu Yuan to visit the entire base.

This base is not only bigger than Lu Yuan imagined, but also has a lot of good things in it.

There are not only as many as twelve flying saucers in this base, but also a much larger starship.

Not only that, but there are thousands of unmanned weapons and equipment in the base.

Although the weapons were temporarily unusable due to lack of energy, they were not damaged by themselves.

With these things as the object of study, Lu Yuan believed that Zhu Xia's military science and technology would definitely make a leap forward in the future.

In addition to these, Lu Yuan also found a huge ammunition depot and aircraft runway underground.

The entrance to the runway has now been blocked by glaciers, and Lu Yuan originally wanted to directly clean up the glaciers covered outside.

However, after thinking about it for a while, he gave up this plan, after all, this base will eventually be handed over to Zhuxia.

Clearing the glacier now is difficult to explain, and it is easier to expose the base in advance.

Lu Yuan stayed in the base for another half a day, and he didn't move anything except for taking a pair of maps.

......

On this day, Lu Yuan made a phone call to Professor Sun.

When he received Lu Yuan's call, Professor Sun was still researching the Xia Dynasty script.

In order to facilitate the study of the Xia Dynasty's writings and artifacts, Professor Sun has now returned to Xishu.

After Lu Yuan learned that Professor Sun was in Xishu, he gave up his original plan for the sake of secrecy.

He simply packed up his things and quickly left the base.

Two days later, Lu Yuan met Professor Sun in Jinguancheng.

Professor Sun was shocked when he learned of Lu Yuan's origin.

It took a while to react.

Then he used his personal relationship to contact a big guy as quickly as possible.

The big guy who learned the news rushed to Jinguancheng to meet Lu Yuan as soon as possible.

Lu Yuan sent all kinds of materials from the base during the meeting.

In the end, Lu Yuan left Jinguan City with a thank you.

At the same time, the most elite team of Zhuxia was also sent to the location of the base as soon as possible.

In order to conceal the real action, Zhuxia also conducted an exercise on the plateau.

By the time everyone turned their attention to the exercise, a scientist had already arrived at the base.

When these people entered the base, they were all stunned by the scene in front of them, and some even collapsed to the ground with tears in their eyes......
