From the appearance alone, these aircraft from prehistoric civilizations are well preserved, and there is no trace of rust on the smooth and smooth shell. If their internal structure is also intact and incomplete, it should not be a problem to fly again.

Xie Xuan's words confirmed her speculation: "Most aircraft can fly, and some have strong attack capabilities. Including the largest one, it theoretically even has the ability to travel back and forth to Mars. Unfortunately, we do not have the ability to replenish corresponding energy for them, so... these things can only be placed here as collections."

Zhao Xinglan was stunned for a moment and asked, "What kind of energy do they need? With the industrial and technological level of human civilization, can't they be produced now?"

"In addition, I think that since there is so much high-tech heritage, if we can organize human and material resources to conduct research, it should greatly promote the improvement of the country's scientific and technological level, right?"

In some previous science fiction movies or online novels, there was always a story about a country or a certain force or organization who happened to get a spaceship crashed by an alien because of an opportunity, and brought it back to study it, which led to the rapid development of its own technological level and dominating the Blue Star in one fell swoop.

Of course, Zhao Xinglan would not believe in cultural works with such exaggerated expression techniques, but the technical level of these aircraft is far beyond human civilization. As long as the country is willing to invest enough resources to study and crack, it should be gained something extraordinary.

"You guessed that we really don't have the energy they need now, or it's too expensive to bear."

Xie Xuan explained calmly: "As for research, the country has invested funds for research. Unfortunately, due to the large gap in technology levels and the serious lack of relevant data, the harvest has been quite limited so far..."

Due to the complexity of the modern industrial science and technology system, it is not easy to crack and imitate any high-tech product. In the early years, relevant departments in China studied imitating Russian aircraft engines and purchased multiple samples for dissection and mapping. Each component was repeatedly studied, but the performance of the final imitation was always unsatisfactory.

The reason is that China's material processing and precision manufacturing technology are not up to standard. The combination ratio of various metal components in each part of the engine, what kind of tempering and processing procedures are required to meet the corresponding technical indicators, and how to achieve the best cost-effectiveness. These are valuable experiences that can be found with a lot of money and time. It is a secret that is difficult to buy even if you have money.

In the early years, China's aviation engine level has been lagging behind Western developed countries, and it has not improved until recently. This is why.

Of course, the countries have long wanted to study and imitate these high-tech creatures of prehistoric civilizations, but the technological gap between them is too big. Not to mention imitation, they can’t even talk about it if they want to learn from some technical experience.

Each aircraft is a unique orphan. If it is dismantled rashly and cannot be restored, it will be destroyed. It is impossible for a second of the same aircraft to be used for experts to compare and study.

So without a complete grasp, scientists will never touch these treasures casually.

After preliminary analysis, a considerable number of the raw materials used for the components that make up the aircraft are extremely rare or simply metal elements on the earth; and the processing and manufacturing requirements for parts are extremely demanding, and many key components must be completed in space microgravity environments, that is, in space stations in low-Earth orbit, such conditions may be possible.

Unfortunately, even the United States today does not have the ability to move a factory into space, so the legacy of these prehistoric civilizations is like flowers in the mirror and moon in the water for the current great human powers, and they can only be watched and envious.

Therefore, the prehistoric civilization creations collected by major countries can only be sealed in the warehouse for a long time and are ready to be left for future generations to deal with.

"... According to the experts' estimates and analysis, it may take another one or two generations, that is, the 100th anniversary of the founding of China, so the domestic scientific and technological level can reach a high enough level to be competent for the research tasks of these aircraft!"

Zhao Xinglan nodded silently. With the development speed of China, the comprehensive national strength had long surpassed the European and American powers by the 100th anniversary of the founding of the People's Republic of China and had already reached the peak of the Blue Star! At that time, he naturally had the ability to study the legacy of these prehistoric civilizations.

Xie Xuan took her to a black triangular wing-shaped aircraft. The object was about the size of a b-52 bomber. In front of it was a half-man-high metal nameplate with a brief description of the origin of the aircraft.

"...The creation of the Mohesala civilization has been around for 93,000 years. In the 1970s, a military engineer army dug it out from the underground more than 100 meters deep when it was built in a mountainous area in the north. It was very intact when it was unearthed." Xie Xuan explained.

Not far from this triangular wing-shaped aircraft is a silver-gray flying saucer with a diameter of more than ten meters. It has a delicate appearance and some gear-like patterns on the surface with unknown meanings.

"...The creation of the Chiquan Mountain civilization has been around 15,000 years ago, and it is left over from an alien intelligent species. It was dug out from that ruin by our ultimate defense experts more than a month ago, and there are many good things unearthed together." Xie Xuan said.

Zhao Xinglan thought about it and found that the dark golden strange meteorite he snatched from the Fusang people last time he went to the northwest with her to perform a mission, which seemed to be an item of this civilization, and it looked very difficult.

"Since they are foreign intelligent species, how did they cross the Star Sea World to the Earth? Such a small spacecraft should not have the ability to travel interstellarly, right?" Zhao Xinglan asked.

"Of course, based on some information unearthed in the remains, it can be determined that this is just a transit vehicle similar to a space shuttle. The real large starry sky carrier should have been parked in the geosynchronous orbit at the time." Xie Xuan explained.

No one knows where this smart civilization comes from. It is just because the large ruins are located in a place called Chiquan Mountain in Xinjiang, so they are called "Chiquan Mountain Civilization" by experts.

As archaeological excavations continue, there are more and more important discoveries. Therefore, the secret department has taken over it in full and has designated the large mountain area as a military restricted area, and organized more capable forces to go for inspection and research.

After the flying saucer was unearthed, experts unexpectedly discovered that it could fly. In addition, a lot of information about this civilization was dug out, so they decided to invest more energy in research. Perhaps more exciting results would appear in no time.

Xie Xuan introduced her to the origins of the next sixteen aircraft, including those found in the wild, those fished out of water, those dug out of ruins, and those who were brought back from abroad using unknown means.

"...The aircraft here is just part of the entire collection of the ultimate defense line. There are several aircraft with not particularly advanced technical level. They have been sent to the laboratories of relevant departments for research and have made some progress. Perhaps they can be applied to our own space aircraft in the future." Jie Xuan said at the end.

Zhao Xinglan asked: "So how are the research progress of several other major countries, especially the United States, in this field? It should not be much higher than us, right?"

"Yes, it's almost the same." Jie Xuan smiled.

There were rumors in the outside world that the United States' B-2 stealth strategic bomber used some technologies from the 51-area alien spacecraft, and I don't know whether it is true or false.

Ji Liuyun, who had been silent all the time, suddenly said: "It's a pity that our country was founded a little late. Before the middle of the last century, due to the poor national strength and the corrupt and incompetent government, there were too many good things that foreigners plundered from our country. It was a bit annoying to think about it."

Zhao Xinglan blinked his beautiful eyes and asked thoughtfully: "In order to find the origin of the Aryan race and the secret of the Axis of the World, Nazi Germany sent an expedition team to Tibet. It is said that he also took away a magic car that the gods had taken from a temple. Could it be this kind of aircraft?"

"Not? Most of the valuable ancient books and relics in that temple were plundered by those bastards. After the founding of the People's Republic of China, our people went to investigate and could not find many valuable things!" Jie Xuan said angrily.

Hitler always believed that the Aryan race was descended from the great gods. Therefore, during the heyday of Nazi Germany, the head of state sent many inspection teams around the world to collect various ancient books, history books, myths and biography, trying to find the secrets left by the gods on earth and provide assistance to his ambition to dominate the world.

Later, Nazi Germany was defeated, and all the precious items and information collected by the expedition teams from many sources disappeared. There are rumors that they were all destroyed secretly, or they may have been stolen and divided by the army of Misu. Anyway, no one has seen them again, which has become a historical unsolved case.

Li Ruomei looked at the aircraft and said, "Since that's the case, the deterrent power of the mothership obtained by the Lomonga tribe is not as great as we imagined? Even if its attack power does look terrifying."

"Of course, it's true that the Lomonga people only got such a mothership, and it's still a long time to say that there is no fault at all. But are the Lomonga people now capable of regular maintenance and maintenance of it?"

Xie Xuan smiled and analyzed: "It would be fine if it didn't move. Once it went to heaven, major countries may not have no special means to deal with it."
