God knows how big the underground base in area 52 is. The elevator finally stopped after five minutes.

After the elevator door is opened this time, the world in front of Chen Feng is another flavor.

In the center of the spacious arc-shaped metal dome hall is the two axle ship.

Under the bright light, the streamlined twin axis ship is shining.

The ship is said to be a wreck, but its shape is undamaged and as new as before.

The ship looks like a sailboat supported by two floating plates on the left and right.

It has barrel shaped engines on both sides, which look like two torpedoes.

The engine is three and thirteen meters long. It is a closed structure. There is no turbine in it.

Chen Feng knows the structure and principle of the engine very well.

The first half of the straight cylinder is a force field generator.

The principle of force field is somewhat similar to that of curvature like engine, but its performance is general, and its isolation ability from cosmic dust is poor. The maximum speed is only one third of the speed of light, and the acceleration time is so long that it is heinous.

The second half of the straight cylinder is a jet engine, and the main injection medium is the residual reaction material after battery combustion and energy supply.

Yes, although it's an antique, it also has a dual engine structure.

If you count the third anti gravity engine, it's a three engine.

The passenger compartment is in the middle. It is an olive structure with a length of 25 meters.

From time to time, several researchers in coats patrol around the ship with instruments, and then put the instruments on to test the materials.

Chen Feng simply looked at the ship and didn't care much.

He focused most of his attention on the structure of the underground base itself.

There are dozens of doors inside the hall.

Obviously, there is far more than one hall in the underground base.

He carefully observed the dome structure, and subconsciously calculated the construction of the base, lighting, ventilation system, living material supply and so on.

Although Chen Feng had piloted a two axle ship in the 31st century, the underground base had disappeared at that time. It was a pity that he could not get a glimpse of the real appearance of the 52 area base that countless people wanted in the 21st century.

Well, he actually has a desire to peep.

"Mr. Chen, as you can see, this is the 52 area with the most mysterious and cutting-edge research projects in the world. We have more than 1000 elite personnel from all walks of life to serve the research project of cracking this alien ship. I bet no one on the planet knows aliens better than us," Mendelssohn said proudly.

Obviously, before Chen Feng came, he carefully prepared the welcome speech.

But as soon as he finished speaking, he was a little stuck. Because he reacted, Chen Feng's description of quantum materials in madman conjecture set version 3.0 really accurately described the material essence of the shape ship.

Mendelssohn believes that Chen Feng has never seen the ship and never knew that there were such terrible materials that can self repair across space in the world. The core of the problem was found only from a theoretical point of view.

This is the real master's skill.

I'm making a joke.

Chen Feng paid attention to the scale of 1000 people he said and kept silent. This almost means that the construction cost of zone 52 is at least 10 billion US dollars, and the annual operation and maintenance cost is hundreds of millions of US dollars.

This does not take into account the investment of cutting-edge analysis equipment, which is immeasurable.

If the base is built on the ground, the construction cost can be saved by at least 70%, and the operation and maintenance cost can be saved by 50%.

He expressed his sadness at this.

People who are thieves will always think of others as thieves. They would rather burn money in vain than keep secrets to this extent for fear of being discovered by other countries in the world.

Why bother.

"Mr. Chen, this is part of my analysis report. I didn't find any offensive weapons in this ship. Look at this half-life report. This is the age analysis of the impact terrain below when we found the ship's hiding place."

Chen Feng looked down at the report in his hand. There was nothing new. He was clean.

Mendelssohn is still analyzing excitedly, "as early as 10 million years ago, this ship was already on the earth. And it didn't carry any weapons, which is my argument. I think the civilization behind this ship is full of goodwill to mankind. It should be an observation station and may also lead our civilization forward."

Chen Feng was noncommittal, then pretended not to know and asked, "what about the people in there?"

"No one, no bones. We speculated about the alien body based on the structure of the chair. It is unmanned, but it is placed on earth, which is similar to the function of the probe we put on Mars."

Chen Feng said, "OK."

Mendelssohn's argument that the universe is friendly is supported here.

Chen Feng agrees with some of his views. Fans are really friendly.

However, good people don't live long and harm generations.

Of course, fans may be destroyed by worse villains before they have time to do bad things.

Chen Feng knows more.

Indeed, the two axis ship settled on the earth tens of millions of years ago and went deep into the earth to reach 75 kilometers.

The crew of the ship had already left, but its internal smart brain was not closed. Instead, it quietly monitored the world through neutrino scanning, and then the smart brain would transmit the collected information back to the Mimi mother star or somewhere else through the quantum network.

Chen Feng is not sure whether the MI ship plays an important role in the process of human birth and evolution.

However, future researchers generally believe that the fan ship only firmly plays the role of a pure observer, commonly known as doing nothing.

The energy supply of ships mainly depends on the open solar wing.

Millions of years ago, the fan civilization was forced to be involved in the fierce war with the compound eye civilization, and finally lost.

Since then, the two axis ship has lost contact with the main control computer of the fan family and has become a ownerless thing.

Perhaps since then, the earth has entered the vision of compound eye civilization.

But at that time, humans were only upright apes who had just learned to collect mountain fires. The earth was in a complete vacuum of civilization, and even had no value in captivity.

However, although the two axis ship lost its controller, its brain still faithfully executed the observation command.

In 1947, the two axis ship should leave the earth and return to the maze base according to the original plan.

It quietly drilled to the ground and floated into the atmosphere. At the same time, it sent signals to the parent star or base through high-frequency quantum network, waiting for positioning and traction.

Something happened.

It did not wait for the signal from its parent star or base, and encountered extreme lightning weather at night.

Because of the tens of millions of years of underground latent, the ship's energy is insufficient. After being hit by lightning for many times, it is hit by lightning for many times, which automatically excites the shield, resulting in insufficient energy supply.

It began to prepare to return to the earth's ground according to the predetermined self-protection procedure. At the same time, it spread the solar light wing to recharge with low light at night, and will take off again in the daytime the next day to escape from the atmosphere.

But the black swan effect continued to take effect, and in the process of falling, it was concentrated by anti-aircraft missiles.

If the shield has sufficient energy, the destructive power of the anti-aircraft missile is not even worthy of tickling it.

However, at this time, it just lost its shield due to lack of energy.

The missile destroyed its solar wing and directly caused it to fall in Roseville, which was then "captured" by federal forces.

This is all the analysis of the world-famous "Roseville incident" seen by Chen Feng a thousand years later, coupled with his own new speculation about the fans, and the final analysis conclusion.

Master Chen believes that this is basically in line with the facts.

While chatting, they went to the bottom of the two axis ship.

Chen Feng looked at the open door of the crew compartment of the ship and said, "it's pretty good. No wonder you know there's no weapon system in it. By the way, how did the door open?"

Mendelssohn said awkwardly, "it exploded in a nuclear test. At that time, the door was seriously damaged, but it was repaired by itself. However, opening and closing belong to its normal state, so we have been open all the time. If it is accidentally closed, I'm afraid we have to explode again."

Chen Feng turned his eyes wildly and wanted to give Mendelssohn a thumbs up.

You're tough enough to blow up.

Well, he finally knew the secret that could not be found in the historical materials a thousand years later.

Nuclear test open the door.

Yes, it's very beautiful.

I think it must be a shame, so I didn't save any paper documents. It was only spread by word of mouth.

"All right. If the AI in the fan ship is completely shut down and destroys its data because of energy depletion, you must make great contributions to this bombing."

Mendelssohn's old face is redder.

Ellen was especially good at capturing the information in Chen Feng's words and quickly asked, "fan clan?"

Chen Feng coughed softly, "the alien race we don't know is like a puzzle, so I just named each other Mi Zu, how about it?"

Ellen and Mendelssohn nodded at the same time. "Great."

The assistant even quickly took out a pen and paper to write down the name "fan clan".

Several people entered the cabin.

The wall structure is silver white metal, which feels silky and cool.

Mendelssohn said, "this metal is incredible. It's like life."

Chen Feng smiled and was noncommittal.

If the artificial intelligence inside is still "alive", in a sense, the ship is really a life.

The cabin space is very narrow and compact, and there is no living area. It is all a workshop filled with all kinds of integrated equipment.

The door of the workshop is very narrow, only half a meter high and only more than 20 cm wide. Obviously, it is not for people to enter. It is like a common access door on industrial equipment.

Chen Feng knows why.

In fact, there is a storage bin full of various types of robots under the crew compartment of the fan ship.

If there is a problem with the equipment in the function room and manual rest is required, the fans should control these robots to drill in through brain wave direct connection and implement semi artificial and semi intelligent repair.

However, in the embarrassing 21st century, scholars can't open the door of the storage bin, so they don't know at all.

They can't test directly inside the ship. That's too much.

When they walked inside, they went down, drilled through a small door hole, and finally entered the cockpit.

The cockpit of a fan ship is very different from that of a human ship. There is no visual field at all.

The analysis of later technicians may be that the vision imaging mechanism of the Mimi body is different from that of humans.

Humans always maintain a high dependence on naked eye observation, while fans are more superstitious about cameras or data references provided by monitoring instruments.

Six or seven people crowded into the cockpit.

However, the cabin space is different from the human aircraft in the 21st century. There is no complex operation dashboard at all, only a few strange metal balls.

In front of the ball array is a small chair.

The chair is a hard pure metal structure, and people feel uncomfortable when sitting on it.

According to the shape of the chair, the technicians also speculated and simulated the body shape of the MIMU.

Mendelssohn put his hand over a ball, on which hundreds of tiny arcs like silk appeared.

"Mr. Chen, you can try. It's a little numb in the palm. We speculate that there may be information in it, but we can't recognize it."

Chen Feng's pupils contracted and finally became interested.

He knows the arc very well. It is a means of neural connection. There is a lot of information in it.

But by the time humans could read this information in the 28th century, the ball was really just a ball and had no response.

This phenomenon means that the brain in this ship has not completely stopped!

He quickly opened Mendelssohn's hand. "Don't touch, don't waste energy! Let me come."
