(The data in the previous chapter was wrong and has been revised)

2.1 light years ~ 5.3 light years is just an approximate number.

If you want to determine the starting point of the alien spacecraft, you must board the alien ship and conduct a comprehensive investigation.

The Space Division moved quickly.

Until three months later, in August of the 4th year of Galaxy.

Three newly-built Cicada-class spacecraft have been transported to lunar orbit, and then propelled by hydrogen bombs to quickly speed towards Cicada-class 004.

Now that the support spacecraft has been launched, the Cicada-class 004 is also preparing to land on the alien spacecraft.

On the side of the Earth Headquarters, Hill was still in charge of the coordination work, and she also looked serious at this time, staring at the pictures and various data transmitted by the Cicada-class 004 spacecraft synchronously.

As for the Cicada-class 004 spacecraft, the ones who are responsible for the boarding work are Utgong, Zheng Lin, Diat, Lin Mingyu and others who discovered the alien spacecraft before.

As the captain, Utgong must stay on the spaceship to command, and he prudently instructed Zheng Lin:

"Ah Lin, don't be careless."

"I'll take notice." Zheng Lin nodded, then turned his head: "Diat, let's go!" ”

The two of them controlled the synchronous robot into a small exploration boat, which is the cicada-class spaceship, mainly to facilitate the exploration of planets along the way, there are three models.

At this time, the exploration boat piloted by the two of them is a model that specializes in exploring asteroids.

After the cicada-class spacecraft adjusted its direction, the exploration craft spewed plasma and approached the alien spacecraft little by little.

At the same time, the only deathlight cannon on the Cicada-class spacecraft quickly aimed at the alien spacecraft, and the hydrogen bomb inside the spacecraft was also ready to launch.

Once there is an emergency on the side of the exploration boat, and there is no way to deal with it, then Utgong can only directly kill him.

Half an hour later.

The exploration craft finally docked on a relatively flat hull of the alien ship.

Zheng Lin pressed the grip button, and in an instant, six mechanical claws ejected from the bottom of the exploration boat, which were directly inserted into the hull shell, firmly fixing the exploration boat to the surface of the alien spacecraft.

"Diat, how's it going?"

Diat is manipulating various detection equipment to make more detailed explorations of the spacecraft.

All kinds of feedback data poured in like a tsunami, and the supercomputer that came with the exploration craft quickly analyzed the data.

Soon, a more comprehensive and accurate model of a holographic spaceship appeared in front of the two of them.

"Diat, the data model is complete, you stay on the exploration boat, and I enter the alien spaceship."

"Understood."

Zheng Lin floated over to the traffic cabin in the middle of the exploration boat, and a set of combat-type exoskeleton armor had been prepared in advance, which was specially designed for outer space operations.

The exoskeleton armor quickly opened the shell, revealing the humanoid driver's seat inside, into which he floated and lay in.

In an instant, his synchronous robot sprouted a large number of miniature nanomachine tentacles, which were connected to various devices inside the driver's seat, and then the shell collapsed.

Zheng Lin does not need to belong to the control method such as buttons or keyboards, but directly uses the mind control through the synchronous communication system.

The exoskeleton armor stood up.

"Diat, open the hatch."

"Roger."

Multiply...... The hatch of the traffic cabin opened, and Zheng Lin controlled the synchronization robot, wearing exoskeleton armor and floating outside.

Since the alien spacecraft is flying at high speed and inertia, and its gravity is very small, it must be very careful, otherwise it will easily float out.

You must know that at this time, within billions of kilometers around, there is an empty void, and if it floats out, this synchronous robot and exoskeleton armor will be scrapped directly.

Therefore, this exoskeleton for landing on an asteroid is not humanoid, but similar to the form of a spider robot.

Its chassis is a multi-legged mechanical body, with eight mechanical legs made of high-strength alloy, which can be inserted into the outer shell of the alien spacecraft in an instant, and the body can be fixed to the surface of the spacecraft.

The outer shell of this alien spacecraft is made of silicon-lead-iron alloy material, which has average strength, and is estimated to be designed to protect against radiation, and has already become very fragile after being exposed to outer space for a long time.

The mechanical legs of the exoskeleton armor are easily inserted into the hull.

Zheng Lin manipulated the exoskeleton and crawled towards a hole not far away.

They have conducted a comprehensive study of the structure of this spacecraft before, and chose this landing location because of the hole nearby, which can directly enter the interior of the alien spacecraft, without breaking the hull and reducing the amount of work.

Soon Zheng Lin came to the side of the hole.

It is a hole that was hit by an asteroid, with a radius of 17.6 meters and a depth of 15.4 meters, and a large amount of water ice and dry ice condensed on the surface.

The mechanical legs cautiously probed to avoid collapses and unstable positions.

It took him more than ten minutes to get to the bottom of the cave.

The extremely sharp mechanical leg knife instantly cut through the blocked ice, and a passage appeared in front of Zheng Lin.

It is a passage with a height of 3.53 meters and a width of 4.21 meters, and the searchlight of the exoskeleton shines into the depths of the passage.

Since he didn't come by himself, Zheng Lin didn't have any fear at all, but his actions were still relatively cautious, after all, on the cicada-level 004, there were 15 synchronous robots, and if one was broken, there would be one less, and there would be no replenishment at all.

He looked at the internal structure of the alien ship and began to walk towards the first target.

After more than an hour of twists and turns, I finally came to the location of the first target.

This is a special cabin.

However, looking at the hatch in front of him, which was only 1.52 meters high, Zheng Lin could only use the mechanical leg knife to try to cut through the bulkhead and expand the size of the hatch, otherwise he would not be able to enter it.

Although the hatch is made of aluminum alloy and composite materials, no matter how powerful the material is, it will still age in the face of a long time.

The mechanical leg knife was easily inserted into the bulkhead, and he activated the chainsaw mode, and suddenly a spark burst out of the bulkhead.

Twenty minutes later.

A hole two meters high and two meters wide was cut off, and Zheng Lin entered the cabin.

The cabin was not spacious, and it was a bit cramped for Zheng Lin, who was controlling the exoskeleton armor, with rows of cabinets on one side of the wall.

There's also a thermal reaction in it, which is a nuclear battery center, but there's only a small fraction of plutonium-239 left in it.

He first tested the condition of the nuclear battery system.

It was found that the power generation system of the nuclear battery had been completely scrapped, and the heat energy generated by the nuclear battery was neutralized by the surrounding low temperature.

He tried to remove one of the nuclear batteries, and with great effort, he managed to get one out of it.

He used the magnetic field detector that came with the exoskeleton armor to recheck the plutonium-239 content of the nuclear battery.

The data was fed back to the supercomputer of the Cicada-class 004 spacecraft, and soon according to the decay situation in it, the content of other elements, they could basically determine that this plutonium nuclear battery was manufactured 45300~45400 years ago.

Zheng Lin took out three more nuclear batteries one after another, and found that the manufacturing time was about the same.

Of course, this is not 100% certain, because it cannot be ruled out that it was created by an alien civilization during the flight.

Therefore, he had to spot check the manufacturing time of the nuclear batteries in several nuclear battery centers before he could determine the specific manufacturing time of this spacecraft.

The exploration of alien spacecraft continues.

However, the earth has already launched a research project based on the information found during this exploration.
