Homo sapiens.

(The data in the previous chapter was wrong and has been re-corrected)
2.1 light-years to 5.3 light-years is just a rough figure.

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

The Space Division moved quickly.

Until three months later, that is, in August of the 4th year of Xinghe.

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

At the Earth Headquarters, Hill is still in charge of coordinating the work. She also has a serious expression at this time, staring at the images and various data synchronously transmitted by the Cicada-class 004 spacecraft.

As for the Cicada-class spacecraft 004, those responsible for the boarding work were Wu Tegong, Zheng Lin, Diat, Lin Mingyu and others who discovered the alien spacecraft before.

As the captain, Wu Tegong must stay on the spaceship to command. He solemnly ordered Zheng Lin:

"A Lin, don't be careless."

"I will pay attention." Zheng Lin nodded, then turned his head: "Diart, let's go!"

The two of them controlled the synchronous robot and entered a small exploration boat, which was included with the cicada-class spacecraft, mainly for the convenience of exploring the planets along the way. There are three models in total.

At this time, the exploration boat the two of them were driving was a model specially designed to explore asteroids.

After the cicada-class spacecraft adjusted its direction, the exploration ship spewed plasma and approached the alien spacecraft a little bit.

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

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

After half an hour.

The exploration craft finally anchored on a relatively flat hull of the alien spacecraft.

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

"Dyat, how's the situation?"

Diat is manipulating various detection equipment to conduct a more detailed detection of the spacecraft.

Various feedback data poured in like a tsunami, and the supercomputer built into the exploration boat quickly analyzed the data.

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

"Diyat, the data model has been completed, you stay on the exploration ship, and I will enter the alien spaceship."

"clear."

Zheng Lin floated over to the transportation compartment in the middle of the exploration boat, where a set of combat exoskeleton armor had been prepared in advance, which was specially designed for outer space combat.

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

In an instant, a large number of tiny nanomachine tentacles emerged from his synchronous robot, and these tentacles were connected to various devices inside the driver's seat, and then the shell closed.

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

The exoskeleton armor stood up.

"Dyatt, open the hatch."

"receive."

Zi... The door of the traffic cabin opened, and Zheng Lin controlled the synchronous robot, which floated outside in the exoskeleton armor.

Since the alien spacecraft is in a state of high-speed inertial flight at this time, and its gravity is very small, it must be very careful, otherwise it will easily float out.

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

Therefore, this exoskeleton dedicated to landing on asteroids is not humanoid, but similar to a spider robot.

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

The shell material of this alien spacecraft is a silicon-lead-iron alloy material with average strength. It is estimated that it is designed for radiation protection. In addition, it has become very fragile after being exposed to outer space for a long time.

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

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

They had conducted a comprehensive study on the structure of the spacecraft before, and chose this landing location because of the nearby hole, which allowed them to directly enter the interior of the alien spacecraft without breaking the hull, which reduced the amount of engineering.

Soon Zheng Lin came to the hole.

This is a hole hit by an asteroid. The hole has a radius of 17.6 meters and a depth of 15.4 meters. A large amount of water ice and dry ice have condensed on the surface.

The mechanical legs were cautiously probing, trying to avoid landslides and unstable positions.

It took more than ten minutes before he entered the bottom of the cave.

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

This is a passage with a height of 3.53 meters and a width of 4.21 meters. The searchlight of the exoskeleton shines deep into the passage.

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

He looked at the internal structure diagram of the alien spacecraft and started to walk towards the first target.

After turning seven turns and eight turns for more than an hour, I finally arrived at the location of the first target.

This is a special cabin.

But looking at the hatch with a height of only 1.52 meters in front of him, Zheng Lin could only use a mechanical leg knife to try to cut open the bulkhead and expand the size of the hatch, otherwise he would not be able to get in.

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. He activated the chainsaw mode, and a burst of sparks burst out of the bulkhead.

Two 10 minutes later.

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

The cabin is not spacious, and it looks a bit narrow for Zheng Lin who is manipulating the exoskeleton armor. There are rows of cabinets in one of the walls.

There is also a thermal reaction inside, which is a nuclear battery center, but only a small part of the plutonium 239 is left.

He first checked 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 also neutralized by the surrounding low temperature.

He tried to take out one of the nuclear batteries, and after a lot of effort, he successfully took out one of the nuclear batteries.

He re-examined the plutonium-239 content of the nuclear battery using the magnetic field detector that comes with the exoskeleton armor.

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

Zheng Lin took out three 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 nuclear batteries in several nuclear battery centers before he could determine the specific manufacturing time of this spaceship.

The search for alien spacecraft continues.

But on the other side of the earth, based on the information discovered during this exploration, relevant research topics have been launched.
