More than a dozen hours later, Xinyuan arrived at the Black Hole Corridor.

The battleship jumped out of the nebula, and a huge corridor with a diameter of several astronomical units appeared in front of everyone.

There were a lot of people on the Xinyuan, but except for Ye Fei himself, most of them had only heard of this place, but they had never seen it with their own eyes, and they couldn't help but let out a burst of admiration.

Ye Fei didn't interfere with everyone to take a look at the Western Ocean, but simply ordered Yi Qi to fly the battleship to the other side of the nebula.

It took more than a dozen hours for the new source to fly out of the nebula.

Shortly after leaving the nebula, the battleship detached from the speed of light and took a few close-ups of the nebula before returning to its path - the Orion Nebula as seen from the other direction was completely different, completely different from what everyone was familiar with!

From leaving the nebula to flying to the target, there is still a distance of nearly 1,400 light years, although M67 is the target of this trip, but the goal of Xinyuan's trip is to find a colony star, so it is not a direct flight to M67, but like the deep space plan of the year, to check the galaxies passing through one by one.

However, because the lifespan of red dwarfs is too long, the possibility of storing zài heavy elements is extremely small, so the new source does not stop at every station, but tries to choose yellow dwarfs to dock.

This greatly reduces the workload of exploration, and there is no need to stop every star. It's just that there are a lot of yellow dwarfs, and the interval between berths is at most more than ten light-years, and when it is rare, it can only meet a yellow dwarf in three to four light-years.

In just a few days, Xinyuan visited more than a dozen yellow dwarf star systems, and found one second-class habitable star and six third-level ecological stars. Tong guò calculations can be found. On average, one eco-star can be found every fifteen to twenty light-years. It's a pity that these planets either have too little potential for transformation, or the proportion of heavy elements is too low, which does not meet the requirements of colonization.

June 24, 2223.

The Xinyuan had flown to a position about 240 light-years away from the base star, and the battleship was once again out of the speed of light, and a galaxy was quietly hovering not far ahead.

The bridge immediately became busy, and Xia Zhuoyan quickly obtained the preliminary information of the galaxy through the optical system: "Chief, this star has a mass of ninety percent of the sun and has seven planets...... The fourth planet has oceans! ”

"That's good news, is there an ecosystem?" Ye Fei asked.

"Our position is not good, we can't see clearly." Xia Zhuoyan replied. "But according to my calculations. The position of the fourth planet is out-central in the habitable zone. ”

"Yi Qi, lean over!" Ye Fei said lightly.

The battleship immediately entered the speed of light, and not long after, it appeared near the fourth planet.

The optics immediately aimed at the planet. This time, there is no need for Xia Zhuoyan to report. Anyone with eyes can see the planet's vast forests at a glance.

"Good place. At least a second-class livable star! Hong Liang said excitedly.

This is the second habitable star discovered by Xinyuan, and although it is not known what the proportion of heavy elements is, it can at least be used as an alternative to a colony star.

Ye Fei was about to say something. Ruan Peng suddenly shouted: "Look, this seems to be a city!" ”

As soon as these words came out, the entire bridge fell silent, Xia Zhuoyan didn't need Ye Fei's command, he immediately enlarged the place where Ruan Peng was pointing, and a high-altitude overhead view soon appeared on the screen.

"It's the city!" Ji Xiaotong couldn't help but say, "It's just a little strange...... The edges of the city are too neat, right? Can you zoom in a little more? ”

Everyone is a systematically trained officer, and they are very familiar with the high-altitude overhead view, and they can confirm that Ruan Peng is not wrong after just one glance.

"It's kind of weird." Ye Fei had never seen such a top-down view of the city, "Xiao Xia, zoom in a little more." ”

The image was quickly magnified tenfold, and the city on the ground was clearly displayed in front of everyone's eyes, but everyone couldn't help but be stunned.

Hong Liang's face was incredulous: "This is ...... Walls? Am I right? What kind of civilization is this? ”

The expressions of the others were not much better than his, and they all had a strange weirdness.

"Maybe it's the feudal era." Ye Fei said, "It's a little worse." ”

In addition to the mission of finding colonies, this deep space exploration also has an element of exploring interstellar civilizations.

If it is a powerful interstellar civilization, then the only thing Ye Fei has to do is to observe silently and then detour, if it has just entered the cosmic era, the military will immediately take over, comprehensively help this civilization improve its scientific and technological level, and let them enter the real cosmic era!

Humanity has been fighting alone for too long, and needs allies or vassals. Other countries that were originally from the same earth were a good choice, but everyone came from the earth, and the concept of freedom and equality was deeply rooted in the hearts of the people, even if the country was backward, it was difficult to really become a vassal of the republic.

To cultivate a backward civilization into an interstellar civilization, it is necessary to invest a lot of time, manpower and material resources, starting with basic education, and providing comprehensive assistance.

This civilization has just entered the feudal era, and it is naturally more difficult to cultivate.

"Poor?" Hong Liang glanced at Ye Fei in surprise and put forward his opinion, "Boss, you mean that this place is too backward, right?" I think it's better not to be too clever about vassals. ”

"Actually, I think so, too." Ye Fei looked at Hong Liang and smiled, "What about the aborigines?" Find out and see what it looks like. ”

"Yes!" Xia Zhuoyan zoomed in on the image again, and a gray-skinned, naked creature appeared on the screen.

Yi Qi grinned, revealing two neat rows of teeth: "This thing looks so ugly!" ”

Her words immediately struck a chord from home.

The creature's skin is not only unsightly in color, but also full of wrinkles, looking like a monkey that has just been fished out of a stove pit, which does not at all conform to the aesthetic point of view of humans.

"Hong Liang, do you think this creature has the value of cultivating?" Ye Fei asked.

Hong Liang obviously didn't understand what Ye Fei meant, and said bluntly: "The most important thing for vassals is loyalty, and the key depends on what habits they have. ”

Creatures, including intelligent creatures, have natural personalities, some creatures are cunning and insidious, some are honest and loyal, and what humans need is naturally not an immature white-eyed wolf.

Ye Fei touched his nose and said helplessly: "I know it's not a good habit to judge people by their appearance, but if this thing is really cultivated, it must fight with us, and it will definitely stay by our side all day long, what will you do if you look uncomfortable?" ”

Hong Liang couldn't help but be stunned, thought about it and said, "I didn't think about it......

Ye Fei glanced at the gray creature on the screen regretfully: "Forget it, if this thing is placed next to me, I will definitely not be able to stand ......" (to be continued......)
