Hearing Zhuang Bifan propose to go out and have a look, Sima Yun was also very moved. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 But she hesitated and said, "However, there are a lot of things going on with the fleet, and you just agreed with them to develop other systems. ”

Zhuang Bifan put his head against her shoulder, directly turned off the holographic display screen and said, "We won't go far, just walk around the star cluster." And the small things of the fleet let Hei Yan deal with, and if it can't be solved, it will be sent to me. As for developing galaxies, it doesn't work out in a few decades. ”

Sima Yun frowned and said, "But aren't the motherships all charging?" Many motherships' energy has already been exhausted, and if they are performing space displacement or jumping, it will have a great impact on the mothership's charging.

Zhuang Bifan smiled and said, "It's okay, let's take a few motherships and set off, it won't have much impact." "He does plan to take the mothership with him, the situation of this galaxy cluster is not yet clear, and he does not want to take too many risks.

Sima Yun knew that he didn't want to make himself bored, so he said, "Then let's go out for a walk." ”

Although she had been in the Black Flame space for a long time, she rarely left the Black Flame. Therefore, although the Black Flame Space is also a large cosmic space, she has never really appreciated the charm of the universe. Now Zhuang Bifan wants to accompany her to explore the universe, and she is also happy in her heart.

It is understandable that Zhuang Bifan now claims to be the king of a country, but he, the most important courtier of the king of a country, has never fulfilled his duties as a courtier.

In this one, he proposed to travel far away, and Hei Yan, as the chief of the fleet, not only did not have any admonition to his travel plan, but also fully cooperated. It arranged for other warships to infuse energy into several motherships that had been repaired, so that they could be filled with energy so that Zhuang Bifan could travel as soon as possible.

So Zhuang Bifan took six motherships and headed for the depths of the star cluster.

It is not a problem at all for a mothership with full energy to replace space "in a short distance". Half a day after Zhuang Bifan and their departure, near a binary star system less than five hundred light-years away from the red supergiant where the fleet was temporarily stationed, several huge energy clusters suddenly appeared, and after a burst of energy clusters, six huge motherships suddenly appeared.

From the moment they appeared, these six motherships were sailing towards the binary system at a speed of more than 600 kilometers per second.

The Hanwu was the flagship of this "small" fleet, and Zhuang Bifan and Sima Yun were on this battleship. In addition to the Han Wu, there is one God of War, and there are two other Hero and Warrior classes.

"That blue giant star spins so fast. "Sima Yun knew for the first time that stars also have halos. "Also, this blue aura is so beautiful. ”

Zhuang Bifan said with a smile: "In fact, the earth can also observe a similar star. It's like it's called water. Like this star, they rotate too fast, have a higher flattening rate than most stars, and at the same time throw out stellar material to form a halo. It is said that if the star had been splenning a little faster, the entire star's atmosphere would have been thrown away. I'm afraid this one is also not a lot of production. ”

The large screen on the Hanwu shows a 3D image of a blue-white star. Viewed from the side, the star resembles a blue-white rugby. It has a dazzling blue halo on the outside.

On the surface of the star, there are constant eruptions of jets similar to those of the Sun. The halo is actually due to the high-speed rotation of the star, which is driven by the Hengxing wind to the range of several astronomical units. And within this ring, it turns out that there is also a hot Jupiter. But Jupiter, which has a surface temperature of up to 1,000 degrees Celsius, seems to be absorbing the gas that has been thrown away by the star. Perhaps it is produced because of the accumulation of these gases.

This hot Jupiter is about 1.8 AU away from the main sequence star, and there is also a brown dwarf star in this system with the main sequence star as the apex and at an angle of more than 100 degrees to the hot Jupiter. The brown dwarf star is about five times the mass of Jupiter, less than twice the diameter of Jupiter, and its surface temperature is only 2,500 degrees. This brown dwarf companion star is only six AU away from the main-sequence star.

A three-star system consisting of two stars and one planet is a typical multi-star system in the universe. Originally, this kind of multi-star system was not surprising, and Zhuang Bifan came here mainly because this main sequence star was relatively beautiful. And women are fond of beautiful things.

Sima Yun also thinks this star is beautiful: "It looks like a blue jade." But it glows blue because it's hot. ”

Zhuang Bifan glanced at the star's data and said, "Its surface temperature is not too high. However, such a constant surface temperature difference is also large. The maximum temperature near the equator is about 23,000 degrees, while the poles are only 12,000 degrees. ”

In fact, the color of a star is not just a matter of temperature. Sometimes it is almost necessary to look at the components. Depending on the composition, there is also a difference in color.

Sima Yun also looked at the data and said with a smile: "It's more than ten times larger than the sun." "The data shows that the main-sequence star should be nine times the mass of the Sun. "But if it turns like this, I'm afraid its lifespan won't be too long. ”

Although Sima Yun did not study astronomy, he also learned some knowledge about the universe. Stars keep losing mass. Those stellar winds are actually ejected matter. The faster the loss of matter, the shorter the star's lifespan.

"It should have at least a few hundred million years to live. Zhuang Bifan smiled and said. "Actually, I think it's its companion that is even worse. At such a distance, the brown dwarf star was probably a main-sequence star before, and it is estimated that the matter was swallowed by this star, and finally the distance was large enough to retain the core. "A small star can't shine as brightly as a giant star, but it will slowly cool down and become a black dwarf after tens of billions of years. Instead of a [popping] explosion, most of the material is thrown out.

Zhuang Bifan let the fleet speed up, and soon moved out of the static equilibrium point in this celestial system, and then took a closer look at this huge star. The 13,000-kilometer-long Hanwu can be regarded as a high-speed planet, sailing in the airspace less than 3 million kilometers away from the main-sequence star with an extremely obvious blue bow shock wave.

They stayed with the main sequence for two days before adjusting course and flying away.

Sima Yun stood beside Zhuang Bifan and looked at the stars that were gradually moving away from the big screen. I looked at the flight simulation of the mothership again, and couldn't help but smile and say, "We sail like this, it's easy for other aliens to find out." ”

The fleet's speed has reached 1,000 kilometers per second, and although it is in the same direction as the stellar wind, it is faster than the constant wind, and the mothership is still staring at a very obvious bow shock wave in front of it. This bow shock wave glows, and the energy in it is not small.

Zhuang Bifan smiled and said, "Now we are aliens!" As for being discovered, he was not worried at all. Although there were other forces within this star cluster, Black Flame had only detected some relatively low-level signs of civilization.

"And where are we going now?"

Zhuang Bifan led her to the fleet commander's seat, called up a star map, and said, "Let's take a look here." Here it should be a complex seven-star system. ”

Sima Yun saw that there were indeed seven stars on the star chart, and their orbits were marked, and he couldn't help but be surprised when he looked closely: "This system is too complicated." ”

"It's really complicated, there are so many galaxies in the Black Flame Space, and no multi-star system like this has ever been discovered. "This multi-star system is actually a composite multi-star system. The center is a triumph of giants orbiting in a straight line, and the core star is a supergiant star with two giants of different sizes orbiting it in a roughly straight line on both sides. And both companion stars have companion stars that revolve around them. The larger one has two companion stars, and the smaller one has only one. There is also a sun-sized star orbiting around the six-star system at an outer periphery of about 0.3 light-years, which can also be considered a companion star of the main star.

The outer companion is a well-developed star system with several planets orbiting it. Therefore, it is not entirely correct to say that this system is a seven-star system.

"There are so many planets, do you think there will be habitable planets as well?" Sima Yun looked more and more interested. "Maybe there's a base for interstellar bandits. ”

"There are indeed signs of civilization found there. As for whether it is a base for interstellar bandits, I don't know. ”

"Marshal, the replacement is ready. The commander of the Hanwu turned around at this time to report.

"Act as planned. "Although the fleet is still in the powerful gravitational field of that blue giant, the technology obtained from the Genep people, and based on the technology of the Three-Eyed Civilization, allows his fleet to no longer have as much impact on the space displacement of the mothership through the countervailing effect of the inner field. "Order the entire fleet to be put on alert. ”

"Yes. After the commander of the Hanwu was called, he turned around and ordered. "Check the displacement parameters one last time. If it is correct, immediately enter the space replacement procedure. The whole fleet was put on alert. ”

The space of this replacement is 5,0600 light-years away. The destination is close to the edge on the other side of the cluster, and there is a real possibility that other military forces may exist there.

In fact, Zhuang Bifan's caution is not superfluous. Just near the main star of the multi-star system where this fleet is going, there is a space warship of thousands of ships sailing in the same direction as the rotation of the star at a fixed speed, just enough to ensure that the fleet is always fixed in one position, and the fleet's course orbit is located on the equatorial plane. These modest ships looked like planetary debris orbiting the stars.

Judging from the appearance, these battleships are all warships of the same type, and the scale of the battleships is very "small", and the slender hull is only about four or five hundred meters. Such a size in Zhuang Bifan's fleet is only slightly larger than some auxiliary warships. But there is no doubt that in the environment of this cluster, a warship of this size is more suitable for combat.

Looking closer, these battleships are all gray on the outside, and I don't know if it's the color of the battleship coating or the armor itself. But there is an identical pattern on the right side of the battleship, which is clearly the fleet of a certain power.

In fact, this is the anti-plunder fleet of a nearby civilization. It's just not known why they're here for their stay.
