Homo sapiens.

There are many living examples of this in the database of omnic civilization.

Unless the six-claw civilization is directly connected and can use vacuum zero-point energy, antimatter, and dark matter, it will definitely be difficult to reach 2% of the speed of light.

For a first-level civilization, the difficulty of going on an expedition to another planetary system lies in the speed of the spacecraft, the self-circulation technology of the spacecraft, and supplies along the way.

Li Qingye has no way to change the speed of the spaceship and the self-circulation technology of the spaceship, but he can change the supplies along the way.

This is equivalent to fortifying the wall and clearing the field in ancient wars.

As long as the Homo sapiens company is one step ahead and controls the dark star between the six-clawed giant star and the solar system, the six-clawed people's expedition fleet will lose supplies after approaching the solar system.

However, the space fleet of Homo sapiens can obtain supplies through these dark stars. Under the trade-offs, Homo sapiens can gain a first-mover advantage.

Chapter 662

Galaxy 12, February 3nd.

Solar system, Kuiper belt.

There are three large asteroids in the outer space of the Kuiper belt in the direction of the six-clawed giant star.

The three asteroids are named "Hummingbird Star", "Sparrow Star" and "Swift Star".

After more than three months of transformation, with the nano-robots going all out and the cooperation of a space fleet composed of 300 space battleships, although this place has not reached the level of iron walls, at least for the invading six-claw civilization. In other words, this line of defense is already as solid as a rock.

Of course, over the past three months, the Department of Cosmic Defense has not only transformed asteroids or dwarf planets in this direction, but transformed the entire outer layer of the solar system.

After all, sooner or later, other directions will be transformed, and we just started working together.

Anyway, there are nano-robots now, and it only takes a few months to transform an asteroid or dwarf planet.

Although the Cosmic Defense Department attaches great importance to the defense line in the outer layer of the solar system, they have also begun to implement the plan to fortify the wall and clear the field that Li Qingye explained before.

The star ring electromagnetic acceleration pipeline of Swift star.

Six fireships were launched in a row, and their flight direction was the six-claw superstar.

Six more Tinder spacecraft will be launched next month.

In fact, many fireships have also been launched in other directions.

Since it is necessary to seize the opportunity, the interstellar space in other directions must not be let go. In case civilizations of other planetary systems send space fleets to the solar system, Homo sapiens can at least discover them in advance.

Although the weapons of other first-level civilizations are not sure, there is no doubt that the first-level civilization must have the ability to wipe out the surface of the planet.

The management of Sapiens Company certainly does not want the war to start within the solar system.

Even if you want to fight, you have to attract the flames of war to interstellar space or other planetary systems.

For example, this time the invasion of the six claws.

Du Wei, Maung Gu and others are secretly forming an interstellar expedition fleet according to Li Qingye's instructions.

Homo sapiens not only wants to defeat the Six Claws, but also plans to sneak attack on the opponent's home planet, and completely kill the opponent in the bud.

After inspecting the progress of the construction of weapons and equipment in the Swift star fortress, Du Wei left in a hurry and went to another asteroid fortress.

And the plan to clear the walls and clear the wilderness, itself contains the dark star plan and the interstellar fortress plan, and these projects need to be taken care of by him.

Fortunately, the preparatory work for the Star Expedition Fleet was taken over by the Earth Defense Department, otherwise he would have been even busier.

While Du Wei was busy investigating the asteroid fortress, Hill's communication request popped up in front of him.

He connects directly to the holographic communication.

Hill's figure appeared immediately.

"Minister Du Wei, there is good news."

"Oh? Could it be that the six-clawed man did something?" Du Wei seemed to have thought of something.

Hill smiled and nodded: "Yes, after half a month of continuous monitoring, the six-clawed expeditionary fleet has entered a state of inertial flight, and its flight speed has stayed at 1834 kilometers per second..."

Hearing this data, a smile appeared on Du Wei's face immediately: "1834 kilometers per second? This speed is only 0.6% of the speed of light. It seems that the technology of the Six Claws has not made much progress."

"After all, it's only been a few years since the other side ended the civil war, and the level of technology will definitely not improve by leaps and bounds, unless they also obtain technical information from other first-level civilizations."

Du Wei pondered for a moment, but he was still a little worried: "Minister Hill, please continue to monitor the other party. Before we have a formal fight, we can't take it lightly."

"Don't worry, I understand Minister Du Wei's worries." As the head of the intelligence department, Hill certainly wouldn't make such an arbitrary conclusion.

In case the Six Claws also detect an abnormality in the solar system, deliberately hide their strength, and wait until they get close to the solar system before going all out, that is not impossible.

One cannot be too careful when dealing with any alien civilization.

But now that the speed of the six-claw expedition fleet has been preliminarily determined, Homo sapiens must make corresponding adjustments.

According to the speed of the six-claw expeditionary fleet at this stage, if Homo sapiens also sends a fleet, the two sides will sail in the opposite direction.

The expedition fleet of the six-clawed people will travel about 0.8 light-years, and will encounter the Homo sapiens expedition fleet that travels about 2.4 light-years.

In other words, the battlefield is not around the solar system, but around the six-claw superstar.

For this reason, the Space Reconnaissance Department, the Space Defense Department, and the Earth Defense Department held a strategic meeting to discuss how to fight.

As for whether the six-clawed people may have come to the solar system for friendly exchanges, Homo sapiens directly ruled out this possibility.

It is very difficult for cosmic civilizations at the same level to get along friendly.

After all, trust is a big problem, not to mention some ambitious civilizations.

In the eyes of Homo Sapiens, the six-claw civilization is definitely not the kind of civilization that is willing to get along with each other. The other party's home planet lacks resources. This is doomed that the six-claw people will not easily give up the possibility of colonizing other planetary systems.

In addition, the Six Claws are very cruel and ruthless to their own people, how can they get along well with human civilization.

Therefore, Homo sapiens has regarded the fleet sent by the Six Claws as an imaginary enemy from the very beginning.

Inside the virtual space of the strategy meeting.

Maung Gu narrowed his eyes, and there was a trace of murderous intent in his words: "The information from the Space Reconnaissance Department is very important. According to the speed of our battleship, we can preemptively strike."

"It is indeed possible to strike first, but my suggestion is to send three expeditionary fleets, one of which will face the six-clawed expeditionary fleet head-on, and the remaining two will directly attack the six-clawed superstar and completely destroy this civilization." The staff officer of the Space Defense Department Chang Kim Ji-woong suggested.

"Three fleets? Go straight to Huanglong?" Du Wei hesitated.

Jin Zhixiong saw Du Wei's worries, and he explained with confidence: "I know that the minister is worried that the fleet that is facing it head-on will startle the enemy and make the six-claw people's civilized land strengthen their vigilance, so we need to make a time difference."

"Tell me about your plan."

Jin Zhixiong pointed to the star map in front of him: "Look, everyone, according to the calculation of the speed of the spaceships on both sides, our speed is three times that of the other side, so even if our expeditionary fleet reaches the six-claw superstar, the other side's space fleet has only sailed 3 It's only light years..."

"In this way, we only need to face the enemy fleet head-on, lay an ambush in advance at a position 1.06 light-years away from the six-claw giant star, and control the dark star in this area. At that time, we can attack the six-claw man's expedition at the same time." Fleet, homeland attack."

According to this plan, everyone re-simulated tens of thousands of times on the supercomputer, and found that there was no major problem, so they decided to adopt Jin Zhixiong's plan.

Chapter 663 Fortress ([-])

Galaxy for 15 years.

In the interstellar space 0.083 light-years away from the solar system.

It is dark here, and there is no other light source except for the distant starlight.

open.

deep.

silence.

It is the eternal theme of this starry sky.

At this moment, an irregular asteroid with a radius of about 288 kilometers slowly drifted past.

The escape velocity of the star is only 13.5 kilometers per second, and the direction of movement is not the solar system, but away from the solar system.

In fact, the trajectories of the stars in the starry sky are unpredictable.

Suddenly, a Pylon spacecraft flying over from the Cooper Belt of the solar system slowly approached the asteroid until the speed of the two sides remained the same and entered the companion flight mode.

The Civilization Spark storage compartment of the Tinder spacecraft opened, and then a carrier rocket carrying the Civilization Tinder was ignited and launched, flying towards the asteroid 12 kilometers away.

Less than 3 minutes.

The launch vehicle carrying the Civilization Spark successfully landed on the surface of the asteroid.

Immediately, the transport capsule of the launch vehicle bounced open, revealing the spark of civilization inside, an improved version of the spark of civilization, added the life metal of Homo sapiens, and used the nuclear fusion power system of the spark spacecraft to transmit power over long distances.

Soon, a large number of living metal particles spread to the surface of the asteroid like a tide.

The dark surface of an asteroid welcomes its first visitor in billions of years.

The Zhina auxiliary system of the Pinder spacecraft quickly plans the development plan by scanning the composition of the asteroid.

A dozen or so synchrobots are activated.

Immediately, one of the cabinets storing the synchronous robot popped open automatically.

Zizi... A white mist came out of the cabinet, and the frozen synchronous robot quickly thawed, and the human face on its head slowly squirmed for a few minutes, and finally the robot opened its eyes:

"Are you at your destination?"

Zhang Yu's synchronous robot floated out of the cabinet.

At this time, other team members also came online one after another.

"team leader!"

Zhang Yu looked at the others: "According to the task arrangement, let's start working!"

"Say it!"

In the control room of the spacecraft, Zhang Yu carefully checked the specific situation of the asteroid.

At the same time, a small transport spacecraft carrying 6 synchronous robots flew out of the Tinder spacecraft and landed on the asteroid.

The asteroid is called "Stonefish".

After reading the specific situation of Stonefish, Zhang Yu showed a smile on his face: "Not bad! Stonefish actually contains 1.2% iron and 2.9% aluminum plus other resources, which is better than other asteroids in interstellar space." a lot of."

"Indeed, this saves us a lot of effort." The vice-captain and construction engineer Barus also laughed.

The resource situation of the stone fish star has indeed reduced a lot of their troubles.

After all, the core components of dark stars in interstellar space are mostly water ice, dry ice and silicate, and the content of metal elements is very small.

"Report, Cage and the others have successfully landed in the Fisheye impact crater of Stonefish."

Zhang Yu turned his head and ordered: "Let them start manipulating the nanorobots to build a landing platform."

"receive."

Although the accompanying flight of the Pinder spacecraft is semi-inertial, it only needs to use the auxiliary thrusters occasionally to modify the flight direction, but the working medium of the Pinder spacecraft is limited, and they must try not to waste it.

In less than 23 hours, the landing platform in the Yumu impact crater was modified.

Zhang Yu, who received the news, immediately directed the Pyro spacecraft to land on Stonefish.

When the Tinder spacecraft successfully landed on the Stonefish planet, it meant that the work of transforming the Stonefish planet had begun in an all-round way.

First of all, the first facility to be built is the water resource refining plant, followed by the nuclear fusion power system manufacturing plant.

The joint operation of civilized tinder and life metal can reproduce most of the current Homo sapiens technology, which naturally includes controllable nuclear fusion power generation technology.

After 17 days.

After the Stone Fish Star No. [-] nuclear power plant was put into use, the productivity of nano-robots and controllable microorganisms with abundant electric power exploded exponentially.

At this time, inside the command center of Stone Fish Star Fortress.

Zhang Yu looked at the star map of Stone Fish within a radius of 5 million kilometers. This is a very high-precision star map, and all asteroids with a star body larger than 1 meter this time are recorded in it.

I saw that the star map was densely covered with light spots, and these light spots were asteroids floating around.

Vice-captain Barus spread his hands helplessly: "Captain, there are no large asteroids within a radius of 5 million kilometers."

The large asteroids they refer to refer to asteroids with a star radius of 100-1000 kilometers; and stars with a radius of 1000-3000 kilometers are called dwarf planets;

半径10～100公里的星体为中型小行星；半径1～10公里的星体为小型小行星；半径低于1公里的星体，则是微型小行星。

At this time, there are only 5 medium-sized asteroids, 27 small asteroids, and 428 tiny asteroids in the star field with a radius of 58397 million kilometers of Stone Fish.

The surrounding resources are so poor, which is not beyond Zhang Yu's expectation. After all, this is an empty interstellar space. He randomly circled four of the medium-sized asteroids:

"Let's focus on mining these 4 medium-sized asteroids first!"
