Homo sapiens

Galaxy 15 years.

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

It's dark here, and there are no other light sources around except the distant stars.

open.

Deep.

silence.

This is the everlasting theme of this starry sky.

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

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

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

Suddenly, a Spark spacecraft flying from the Cooper Belt of the solar system slowly approached the asteroid until the two parties' flying speeds were consistent and entered companion flight mode.

The civilization fire storage compartment of the fire spaceship was opened, and then a launch vehicle carrying the civilization fire was ignited and launched, flying towards the asteroid 12 kilometers away.

Less than 3 minutes.

The launch vehicle successfully landed on the surface of the asteroid carrying the spark of civilization.

Immediately, the transport capsule of the launch vehicle popped open, revealing the Civilized Fire inside. An improved version of the Civilized Fire was added with the Homo Sapiens Company's version of life metal, and the nuclear fusion power system of the Fire spacecraft was used 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 the asteroid welcomed its first visitor in billions of years.

The Zina auxiliary system of the Spark spacecraft quickly planned a development plan by scanning the composition of the asteroid.

A dozen synchronized robots are activated.

Immediately, one of the cabinets storing synchronized robots popped open automatically.

Sizzling... A white mist emerged from the cabinet. The frozen synchronous robot quickly completed the defrosting, and the human face on its head slowly squirmed for a few minutes. Finally, the robot opened its eyes:

"Arrived at your destination?"

Zhang Yu's synchronized 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!"

"receive!"

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 synchronized robots flew out from the Spark spacecraft and landed on the asteroid.

The asteroid is named "Stonefish".

After reading the details 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." Vice captain and construction engineer Barus also laughed.

The resource situation of Stone Fish Planet 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, with very little metal content.

"Report, Cage and the others have successfully landed in the Fish Eye Impact Crater on Stonefish."

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

"receive."

Although the accompanying flight of the Spark Spaceship is semi-inertial and only requires the occasional use of auxiliary thrusters to modify the flight direction, the working fluid of the Spark Spaceship is limited, and they must try not to waste it if they can.

In less than 23 hours, the landing platform in Yumu Impact Crater was modified.

After receiving the news, Zhang Yu immediately directed the Fire Spaceship to land on the Stone Fish Planet.

When the Spark spacecraft successfully lands on Stonefish, it means that the work of transforming Stonefish has begun.

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

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

17 days later.

After the Stonefish Planet No. 1 Nuclear Power Plant was put into use, the productivity of nanorobots and controllable microorganisms that received abundant electrical energy exploded exponentially.

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

Zhang Yu looked at the star map within a radius of 500 million kilometers of the Stonefish star. This is a very high-precision star map. All asteroids with a body exceeding 1 meter this time have been recorded.

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 500 million kilometers."

The large asteroids they refer to refer to asteroids with a radius of 100 to 1,000 kilometers; stars with a radius of 1,000 to 3,000 kilometers are called dwarf planets;

Stars with a radius of 10 to 100 kilometers are medium-sized asteroids; stars with a radius of 1 to 10 kilometers are small asteroids; stars with a radius of less than 1 kilometer are micro asteroids.

At this time, there are only 27 medium-sized asteroids, 428 small asteroids, and 58,397 micro-asteroids in the star field with a radius of 500 million kilometers.

The surrounding resources were so poor, which did not surprise Zhang Yu. After all, this was an empty interstellar space. He casually circled four medium-sized asteroids:

“Let’s focus on mining these 4 medium-sized asteroids first!”

These four medium-sized asteroids have relatively high metal content and have become priority mining targets for the Stone Fish Fortress.

"No problem, arrange it immediately." Kaneda Wangfumi, who is responsible for remote mining work, nodded.

Half an hour later, a 5,000-ton mining spacecraft flew towards the target at a speed of 100 kilometers per second.

Zhang Yu began to prepare for the manufacturing of weapons and equipment.

"Ebony Springs!"

"Captain, what's going on?" Wu Muquan, who was in charge of combat preparations, floated over.

Zhang Yu didn't waste any time: "Which of the weapons and equipment plans of the Ministry of Space Defense are you going to use?"

Wu Muquan, who had been well prepared, calmly replied: "Plan No. 53, this is the best arrangement currently based on the resources of our fortress."

"Okay! Get ready quickly! I always feel a little uneasy without weapons to control the situation."

"Captain also gets the underfire phobia?"

Zhang Yu shrugged: "There is no way. The closest border fortress to us is 72.3 billion kilometers away, and the surrounding area is deserted. We don't have any cover here. Who knows if enemies will suddenly appear."

This is also one of the troubles with the Dark Star Project and the Star Fortress Project.

In interstellar space, any first-level civilization with relatively high technology can more or less detect the existence of dark stars.

Once the opponent's spacecraft passes near the solar system, it will definitely give priority to exploiting the resources of the dark star as supplies.

As for why we don't directly enter the planetary system to collect materials, the reason is naturally for safety reasons.

Aliens are definitely not that stupid. They usually do not directly enter a planetary system without checking the internal information of the unfamiliar planetary system.
