Homo sapiens.

He now feels that the Pangu Realm is not enough, because the genetic mutation here is still in a semi-natural and semi-artificial intervention mode, and there is no way to efficiently obtain a large number of new genes.

But on the earth, there is no larger area that can be used to build such a highly sealed biological laboratory.

That is to say, the Second Pangu Realm must be built in outer space, preferably in a region far away from the earth.

After thinking about it, he thought that the large natural satellites of Jupiter were more suitable as the construction site for the second Pangu.

It is best to use a giant structure to wrap the entire planet, so that not only the climate inside can be easily adjusted, but also the interference of cosmic rays and solar energy on the environment inside the planet can be effectively blocked.

At the same time, an entire planet is used as the experimental site, the area is large enough, and the resources are relatively sufficient, which can supply a large-scale biological group to survive.

Li Qingye finally made up his mind and asked the Science Business Department to start discussions on the Second Pangu Realm project, discussing how to build this experimental site.

the other side.

In the face of the sudden alien spacecraft, the Space Business Department is also making various preparations and launching various long-distance detection plans to make the best preparations for landing the alien spacecraft.

Chapter 6 is close at hand

Inside the Ceylon Island Headquarters Building of the Space Division.

Dr. Mikoyan is discussing with a group of executives how to deal with the alien spacecraft.

Meng Haiyang, the person in charge of the Interstellar Exploration Office, spread his hands helplessly: "Minister, if we want to launch another Cicada-class spacecraft, there will be too little time!"

Chen Jianxiong, who came to observe the meeting, did not agree with Meng Haiyang's idea: "No, I suggest launching a few more cicada-class spaceships there. On the one hand, it can be just in case; You can continue to travel to deep space and explore more distant areas."

Hearing what Chen Jianxiong said, Mi Gaoyang thought for a while, then nodded: "No problem, isn't it just a few cicada-class spaceships, we can still squeeze out part of the production capacity."

In fact, the cost of the Cicada-class spacecraft is not high. The part that really increases the cost of the Cicada-class spacecraft is the propelling hydrogen bomb carried by the spacecraft.

After all, the cost of thousands of miniature hydrogen bombs is not cheap. If it were not for Homo sapiens company’s heavy water enrichment of seaweed, which can lower production costs, the consumption of thousands of miniature hydrogen bombs on this cicada-class spaceship is really not something ordinary forces can afford of.

Even America, which was in its heyday in the past, couldn't afford a spaceship like the Cicada-class spaceship. After all, refining heavy water and making hydrogen bombs is a very uneconomical investment for a capital force.

It is only in the way of Homo sapiens that we can invest regardless of cost.

Mikoyan and the others discussed for a while and decided to launch three more Cicada-class spacecraft.

The head of the Space Equipment Office also said there was no problem.

After all, the production line of the Cicada-class spacecraft is still in production. There is currently one in stock and one is under construction. The factory can produce one Cicada-class spacecraft every three months on average.

But now that the situation is urgent, they plan to increase production, change the previous one shift per day to four shifts per day, and directly increase the manpower by three times. It is estimated that the construction of two cicada-class spacecraft can be completed in less than two months.

After discussing the production of the Cicada-class spacecraft, another organization under the Space Business Department, the Cosmic Observation Office, also stood up to speak at this time.

The person in charge is a rare white-haired old man. Obviously, this person was already very old before he joined Homo Sapiens. Even if he used various life-extending technologies, he could only increase his lifespan by part of it. There was no way to completely rejuvenate his appearance.

The old man didn't care too much about this, especially for the old-school scientists who study cosmic astronomy. They have more theoretical research in this field and rarely involve open and secret struggles between various forces, so their ideas are more "naive".

This old man was from Lucia's side before, and he was dug out by Mikoyan.

In Homo sapiens' space business department, the proportion of employees from Lucia is very high, reaching about 17.3%.

Therefore, the space business department is somewhat Maoxiong's style.

The old man stood up: "Dear colleagues, our Cosmic Observation Office has some opinions on the situation of this alien spacecraft."

Everyone did not make a sound, quietly waiting for the next step.

The old man continued: "Backing back from the flight direction of that alien spacecraft, we can roughly lock on the route that the other party traveled before, but in that route area, the nearest planetary system also reaches 18.4 light-years. Based on this Judging from the current speed of a spacecraft at 15 kilometers per second, it will take 36.8 years to fly, is this possible?"

is it possible?

Everyone was lost in thought.

Even if the alien spacecraft used to be 10 times faster than it is now, it would take 3.68 years to reach its current position.

The old man didn't hide it either, and continued:

"From the detection data of Cicada-class 004, I found that this spacecraft was very likely to use a nuclear fission power system, but the radioactivity in its core is almost gone. In its graphite buffer layer, the carbon-14 magnetic field feedback That equates to around 16% of the forecasting model..."

Everyone immediately realized that the half-life of carbon 14 is about 5700 years.

As a buffer layer of a nuclear fission reactor, carbon 14 will definitely appear in the graphite nest due to the absorption of thermal neutrons.

But now in the graphite nest inside the alien spaceship, the magnetic field feedback of carbon 14 is only equivalent to 16% of the prediction model, which can only show a conclusion: the carbon 14 in the graphite has passed about two and a half half-life.

This also points to the fact that the nuclear reactor of the alien spacecraft has stopped working for at least 1.3 years.

But the old man didn't finish his sentence, he continued to add:

"If it's just that carbon 14 is not found, it doesn't mean anything, but I found the existence of another element in another analysis report. Although the content is already negligible, the distance between the cicada-level 004 is relatively close. , or found a part of the weak magnetic field signal, this element is plutonium 239."

Many people who turned their heads quickly discovered the key point in an instant.

The half-life of plutonium-239 is 2.41 years.

There are still traces of plutonium 239 remaining, which means that the downtime of the nuclear reactor of the spacecraft must not exceed 2.41 years.

Plus the residue of carbon 14 found above.

It can be seen from this that the downtime of the nuclear reactor of the alien spacecraft should have been between 13000 and 24100 years ago.

The old man came to a conclusion: "In other words, there is a high probability that all the creatures in this spaceship have died."

Another executive shook his head: "Not necessarily, maybe the other party has body freezing technology, and the temperature inside the alien spacecraft is very low at this time, there is a high probability that alien creatures will be frozen in the spacecraft."

The old man did not refute this, because it was indeed very possible, and he said another thing:

"I have another discovery, that is, the alien spacecraft itself is very complete. According to the general laws of space travel, if you do not take the initiative to slow down in this kind of empty interstellar space, the spacecraft will basically not slow down too much."

Of this point, all the employees of the space business department present are naturally very clear.

"Since the speed of the spacecraft cannot be slowed down too much, let's calculate with the limit speed of 30 kilometers per second. If this spacecraft flies from a planetary system 18.4 light-years away, it will take 18.4 years. The nuclear fuel of the spacecraft can support so long?"

Hearing this, everyone was thoughtful.

Even if you save money and freeze your body all the way, based on the current detection data, the 8 nuclear reactors and 344 plutonium nuclear batteries found, the fuel of the spacecraft will not last for 3 years.

After all, only 239% of the plutonium 33 fuel in those nuclear batteries is left, and there is still a small amount of plutonium 239 left in the reactor residue.

This shows a problem. After the nuclear reactor stopped working, the nuclear battery continued to operate for a period of time.

It can be seen from this that the spacecraft flew from a certain planet to the solar system about 4.3 to 5.41 years ago.

After determining the time range and the speed range, it is natural to determine how many light-years away from the solar system the other party's starting planet is.

The alien spacecraft has been flying for 4.3 to 5.41 years, during which the speed is about 15 kilometers per second to 30 kilometers per second.

It can be concluded that the voyage of the alien spacecraft may be around 20 trillion kilometers to 51 trillion kilometers.

This distance is far, indeed quite far, but on a cosmic scale, it is almost close at hand.

After all, a light year is only 9.46 trillion kilometers.

From 20 trillion kilometers to 51 trillion kilometers, it becomes light years, which is 2.11 light years to 5.39 light years.

This scale is indeed close at hand.

Chapter 6 and Three

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.
