Leah smiled and said: "Senior, this is the outer defensive fortress of the capital star. It is about [-] light hours away from the capital star. Next, we must fly at sub-light speed for [-] hours to reach the capital star!"

Yang Lin nodded. The distance of fifteen light hours is even farther than that of Pluto from the sun. Alpha Lyrae can still display such strong visible light radiation. From this, one can imagine why this star (33 times the volume of the sun) is in It would be so bright in space.

After crossing the defense circle of the capital star of the Tianqin civilization, some man-made celestial bodies can be seen from time to time during the next voyage.

There are many large military battle fortresses, industrial planets, and habitable planets.

The minimum diameter of these human planets is more than 2000 kilometers, and the largest diameter reaches more than 1 kilometers. There are even some resource stars transferred from other galaxies.

Compared with these big men, the New Earth, where humans live, is simply a small inhabitable spaceship.

From this, one can imagine how profound the fifth-level civilization is.

According to Leah, within a radius of one light-year with Alpha Lyrae as the core, there are a total of more than 1 celestial bodies with a diameter of more than 90.00 kilometers, [-]% of which are artificial celestial bodies, and the remaining [-]% are resource stars. .

Most of these resource planets are Jupiter-like planets and ice giants collected from the Lyrae α radius within hundreds of light-years by the Lyrae civilization. More than 90.00% of these planets are composed of hydrogen and helium. Hydrogen and helium resources are extracted from the planet, and various heavy elements are synthesized through nuclear fusion reactions at the same time.Then use these heavy elements as raw materials to synthesize materials to ensure the supply of materials in the capital star field.

In the star field of the capital of the Tianqin civilization, there are also more than 50 trillion people living in it, accounting for one-twentieth of the total population of the Tianqin civilization.

Among them, the parent star Phoenix has a population of less than one billion, and the rest are distributed among large and small artificial celestial bodies.

Although Chen Xin was calm on the surface, his evaluation of Tianqin civilization was a level higher in his heart.

Thirty hours of flying time passed quickly.

When Leah called Chen Xin out of the lounge again, the Princess was already less than 2000 million kilometers away from Phoenix.

But when Chen Xin came to the command center, what he saw through the porthole was not Phoenix, but a brown dwarf with a diameter much larger than Jupiter.

A so-called brown dwarf is a gaseous object that resembles a star but is not massive enough to ignite fusion reactions in its core.Its mass is between that of a star and a planet.It is the object between the smallest star and the largest planet.

This brown dwarf is called the Hero star by Leah. Its diameter is about five times that of Jupiter, almost half that of the sun, but its mass is only 5.00% of the sun. Its surface is dark red and it is about ten distances away from Alpha Lyrae astronomical unit.

Hero is the god of war in the myths and legends of the Tianqin tribe, so one can imagine its status in the hearts of the Tianqin tribe.

Due to the huge volume and mass of α Lyrae, the stellar wind suffered by Hero is larger than that of Jupiter in the solar system. At its north and south poles, two circles of gorgeous aurora composed of dark blue halos can be seen.

In addition to the solar wind, the formation of the aurora on the Hero star also has its special mechanism.

Among the satellites of the Hero star, the volcanic activity on Hero's moon is very strong, often ejecting

When such charged particles break into the strong magnetic field of the Hero Star, they will be accelerated to very high speeds in the polar regions of the Hero Star. These high-speed high-energy particles collide with the Hero Star's atmosphere and form in the Hero Star's atmosphere Spectacular aurora sights.

The Phoenix Star should be called Hero Satellite in the strict sense. It belongs to a natural satellite of He Luo Star, and it is also the largest one.

But Chen Xin still didn't see it.

At this time, the Princess is slowly berthing into the Hero Airport.

The Tianqin civilization built a super airport around Hero on the synchronous orbit of Hero.

The essence of this airport is a super-large ring. The cross-section of the ring is similar to a rectangle, with a cross-sectional area of ​​more than 500 square kilometers, a radius of more than 100 million kilometers, and a circumference of more than [-] million kilometers.

In this ring alone, more than 50 million people work and live in it. This is also the largest airport in the Tianqin civilization, and it can park [-] satellite-class warships.

Of course, the role of this ring is not limited to the airport, it is also the largest particle collider of the Lyra civilization.

It can accelerate protons to almost infinitely close to the speed of light, and the energy generated by the instant impact can collapse the space-time within a radius of one meter, making it a meaningless domain.

This is also the most powerful experimental equipment produced by the fifth-level civilization, and further up is the circumstellar accelerator that only the sixth-level civilization has.

After the "Princess" spacecraft officially approached, Chen Xin, accompanied by Leah, boarded a rail train that entered the interior of the airport, and then transferred to the docking port of a small meteor star spacecraft.

After entering the spaceship, the spaceship separated from Hero Port without a sound, and then slowly flew to the ultimate destination of the trip—Phoenix Star.

This time when Chen Xin visited Tianqin Civilization, neither Chen Xin nor Leah wanted to reveal any rumors, so his arrival seemed extremely low-key.

After flying for about an hour, the true face of Phoenix Star finally appeared in front of Chen Xin.

The Phoenix Star is a little smaller than the earth, with a diameter of only about 60 kilometers. In front of the Heluo Star with a diameter of [-] kilometers, the Phoenix Star is completely small.

But it is also because of the existence of Heluo star that such a powerful fifth-level civilization was born on Phoenix star.

In fact, for many Lyrae people, they can live without Alpha Lyrae, but they absolutely cannot live without Hero.

Because according to the distance from Phoenix to Alpha Lyra, the heat radiation received by Phoenix is ​​simply not enough for it to maintain a sufficient surface temperature, and it is impossible for liquid water to exist.

Liquid water is precisely one of the three natural conditions for the survival of carbon-based civilization.

But with the Hero Star, it is different. Although the Hero Star is not a real star, its surface temperature has reached 400 K. The heat radiation received by the Phoenix Star, which is 300 million kilometers away from it, , just enough to keep the surface of Phoenix at a suitable temperature of around [-]K.

Coupled with the dense atmosphere on the Phoenix star, the gas types in the Phoenix star atmosphere are similar to those of the earth, and are also composed of nitrogen, oxygen, carbon dioxide, and inert gases.

Its surface atmospheric pressure is 1.2 times that of the earth's surface, and the acceleration of gravity is only 0.7 times that of the earth, which is why the Lyraens look much slimmer. (to be continued~^~)
