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

2.1 light-years to 5.3 light-years are only approximate numbers.

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 sprang into action.

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

Three newly built Cicada-class spacecraft have been transported to the lunar orbit, and then used hydrogen bombs to propel them quickly towards Cicada-class 004.

Now that the support spacecraft has been launched, Cicada-class No. 004 is also preparing to land on the alien spacecraft.

Over at Earth Headquarters, Hill was still responsible for coordinating the work. She also looked serious at this time, staring closely at the pictures and various data transmitted simultaneously by the Cicada-class 004 spacecraft.

As for the Cicada-class spacecraft No. 004, the people responsible for the boarding work were Wu Te Gong, Zheng Lin, Diat, Lin Mingyu and others who had previously discovered the alien spacecraft.

As the captain, Wutgong must stay on the spacecraft to take command. He cautiously ordered Zheng Lin:

"Alin, don't be careless."

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

The two of them controlled the synchronized robot and entered a small exploration craft. This is the Cicada-class spacecraft that comes with it. It is mainly used to facilitate the exploration of planets along the way. There are three models in total.

The exploration boat driven by the two at this time was a model specially designed to explore asteroids.

After the Cicada-class spacecraft adjusted its direction, the exploration craft spewed plasma and moved closer to the alien spacecraft.

At the same time, the only death ray 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 an unexpected situation occurs on the exploration ship and there is no way to deal with it, Wu Te Gong can only take immediate action.

Half an hour later.

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

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

"Diat, how is the situation?"

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

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

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

"Diat, the data model has been completed. You stay behind the exploration boat while I enter the alien spacecraft."

"clear."

Zheng Lin floated over to the transportation cabin in the middle of the exploration boat. A set of combat-type exoskeleton armor had been prepared inside, which was specially designed for outer space combat.

The exoskeleton armor quickly opened its 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 synchronized robot. These tentacles were connected to various devices inside the driver's seat, and then the shell closed.

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

The exoskeleton armor stood up.

"Diat, open the hatch."

"receive."

Zhi... The traffic cabin door opened, and Zheng Lin controlled the synchronized robot and floated outside wearing 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 the surrounding area within billions of kilometers at this time is empty void. If it floats out, the synchronized robot and exoskeleton armor will be directly scrapped.

Therefore, this kind of 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 and can be inserted into the shell of the alien spacecraft in an instant to fix the body on the surface of the spacecraft.

The outer shell material of this alien spacecraft is a silicon-lead-iron alloy material with average strength. It is probably designed to protect against radiation. 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 of the ship.

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

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

Soon Zheng Lin came to the hole.

This is a hole created by an asteroid impact. 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 tried carefully, trying to avoid cave-ins and unstable positions.

It took him more than ten minutes to reach 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 into the depth of the passage.

Since he didn't come here by himself, Zheng Lin didn't have any fear at all, but he still acted relatively cautiously. After all, there were only 15 synchronous robots on Cicada-class No. 004. If one broke down, there would be one missing, and there would be no replacement at all.

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

After twisting and turning for more than an hour, we finally arrived at the location of our first target.

This is a special cabin.

However, 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 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 materials are, they will still age over time.

The mechanical leg knife was easily inserted into the bulkhead. He started the chainsaw mode, and a burst of sparks suddenly came out of the bulkhead.

Twenty minutes later.

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

The cabin is not spacious, and seems a bit narrow to Zheng Lin who controls the exoskeleton armor. There are rows of cabinets on one side of the wall.

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

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 had also been neutralized by the surrounding low temperature.

He tried to take out one of the nuclear batteries, and after a lot of effort, he succeeded in taking out one of the nuclear batteries.

He used the magnetic field detector built into 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. Soon, based on the decay conditions and the contents of other elements, they were able to basically determine that this plutonium nuclear battery was manufactured between 45,300 and 45,400 years ago.

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

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

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

The search for alien spacecraft continues.

But the Earth side has already started relevant research topics based on the information discovered during this exploration.
