More than 18,000 light-years is a long distance, but it is not a huge range in the universe. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoAfter the motherships completed the detection of the surrounding star maps, it was found that this still active star cluster should belong to an immature dwarf galaxy. Within this cluster there are a dense number of stars and many giant planets.

In just one year, Yanhuang detected tens of thousands of supernova light sources located in star clusters. It is a cluster that is constantly forming new stars and constantly having stars dying. Most of the stars here are very large and multi-star systems, and the probability of these stars forming planets is relatively low, and the possibility of life is of course less. At the very least, there were signs of other life in the star fields near the Mothership Detection System, but those seemed to be wandering civilizations. That kind of civilization is almost no threat to them, but Zhuang Bifan still keeps the fleet vigilant against it.

After all the nearby star maps were revealed, he left the motherships near the relocation point. He and Sima Yun brought hundreds of battleships on board the Yanhuang to replace them near a star near the edge of the star cluster.

The Taishan-class command ship was an improved version of the Yue Fei class during the Solar System Campaign, with little change in design shape and size, and improvements in armor, weapons, power, and detection systems.

The Taishan-class can be used as the command ship of an assault fleet, and what Zhuang Bifan brought out this time is an assault fleet. However, he came out with the fleet not to fight, but to explore a planet.

The closer you are to the outer periphery of the cluster, the less dense the celestial bodies become. The proportion of giant stars is also lower. Zhuang Bifan wants to explore this suspected habitable planet. When they get closer, they can avoid the interference of other celestial bodies and really see the planet clearly. It is a rocky planet orbiting a yellow dwarf star with a mass of 1.4 Sun.

"I didn't expect that this planet is more than 90 times more massive than the Earth, and the surface gravity is only a little stronger than the Earth. However, with abundant vegetation and abundant water, I thought that even if there was no real civilization, at least there would be a primitive civilization. After reading the report sent back by the planetary surface expedition team, Sima Yun was half puzzled and half happy.

Zhuang Bifan finished reading those reports earlier than her, and when he heard her say this, he couldn't help laughing: "Its gravitational pull is only a little stronger than the earth's surface, and the price is not without it." Its surface plastic is much higher than that of the Earth, and its higher surface velocity makes its crust more tidal and active than the Earth. ”

Sima Yun remembered that the report she had seen did mention that the sulfur content and carbon dioxide concentration in the air were higher than those of the earth, and both were beyond the safe range of normal earth human adaptation. That's because the planet has hundreds of active volcanoes that are erupting violently. In less than a year, there have been thirteen major earthquakes on the planet's surface with a magnitude of more than 8 on the Richter scale.

That's all evidence of active planetary geology.

Sima Yun was also a little worried about the fact that there were no signs of civilization found on the ground, saying: "Such a planet is more than four billion years old, and it has a lot of water and oxygen, so it should theoretically have produced civilization." But the surface of this planet has not yet found a species that could evolve into a vector of civilization. And the report also said that the variety is not abundant. I think it may be that this planet is more harmful to life. ”

Zhuang Bifan grabbed her waist and said with a smile: "Have you forgotten that there are many supernovae in this star cluster? If you want to say why this planet species are relatively rare, the biggest possibility is because of the gamma burst of supernova explosions." He paused and said. "They said that there may have been many civilizations in the universe, but most of them have not had the opportunity to grow to the stage of space exploration. That may be true. ”

The "they" in his mouth refer to the four aliens who are attached to him, Ficoria.

Sima Yun has also heard of those, but they are not compassionate, the emergence of life is a long process, and the harshness of the universe on life will only make them glad that human beings appear on the earth.

She smiled and said, "Since you're planning to renovate it, you haven't figured out the name yet?"

"It's called New Earth, what do you think?" Zhuang Bifan said with a chuckle. "It's not bad if it's super-Earth. "Although this planet is very different from Earth, and the radius is about five times that of Earth, there are many similarities between this planet and Earth.

The name is just a code name, and Sima Yun is not picky, so he thought for a while and said, "It's better to listen to the new earth." She hesitated for a moment, then added. "But wouldn't it take too much resources and time to renovate it?"

There are many differences between this planet and the earth, the average temperature is several degrees higher than the earth, the carbon dioxide content is as high as 0.5%, which is more than ten times that of the earth, and the hydrogen sulfide content is also as high as 0.03%, which makes the planet's atmosphere a poisonous gas for the humans of the earth.

Maybe they can survive, but it won't do them any good for their lives.

"It's about taking some time. Zhuang Bifan said with a smile. "But it doesn't take too much time. ”

The atmosphere of the new earth is the focus of the transformation, and the pH of the water, although it is acidier than that of the earth, is within the acceptable range. The wavelength of stellar light is even more suitable for human survival than that of Earth.

"The high temperature is due to the high carbon dioxide content and the high water vapor, so if you develop some areas with abundant vegetation and install some air through the system, the carbon dioxide level will drop in a few years. ”

According to the normal thinking of humans, the more forests there are, the more carbon dioxide is consumed. But in reality that is a misunderstanding. In dense deep forests, photosynthesis occurs mainly in the canopy layer, and more plants are respiring all year round, even during the day, the forest consumes far more carbon dioxide than it consumes. Then there is the decomposition of forest plants, which also produces a lot of carbon dioxide.

So too many forests are not necessarily good for the increased oxygen content of the atmosphere.

However, the atmosphere of this new earth has high water vapor, the troposphere thickness of the atmosphere is also large, and the water vapor can warm and humid areas are densely forested. On the contrary, the oxygen content of this planet is not comparable to that of Earth.

Therefore, to transform the new earth, the first step for Zhuang Bifan is to destroy forests.

"The earthquake and the volcano can't be ignored. "To find a planetary transformation, it was Sima Yun who proposed it, but now she feels that she is too willful.

It stands to reason that although the volume of Yanhuang is smaller than that of the Earth, the active space is many times larger than that of the Earth. The Flame Yellow can be used as a home in its own right. Now that I think I have to find a planet, it's a bit redundant. When she saw the renovation plan, she said, "It's going to take a lot of resources and material resources just to build those seismic power stations. ”

Zhuang Bifan didn't care about this at all: "That's not a problem at all. They will be able to produce enough power generation units in a year at most. Moreover, we also need a base. ”

Sima Yun knew that he was comforting himself by doing so. Home is still a very profound concept for her who has just become an alien. Transforming the new earth is probably also to give her a home.

She looked at Zhuang Bifan and didn't speak.

Zhuang Bifan smiled, called up the holographic projection of the new earth, and then magnified a desert and said: "This is still a subtropical desert, but after the transformation, it will become a subtropical monsoon climate, although it is somewhat different from Tianhai, but it is not much different." Moreover, there are plains, mountains, etc., planted with plants brought by the earth, and some animals from the earth, which will not be much different from the earth. Why don't we go and see, if you think it's good, our home will be here in the future. ”

The two of them had nothing to do, and then drove the landing craft to observe the area he was pointing at a low altitude for a while. In the end, Sima Yun also likes to be a place. I think if the renovation is good, it will be good to live here.

They didn't land, they just took a closer look in the sky, and then returned to the Taishan, and finally returned directly to the Yanhuang through space replacement.

Most of Heiyan's resources are used to calculate the coordinates of Heiyan's space, but he still has the spare energy to discuss with Zhuang Bifan how to transform the new earth.

Sima Yun was busy in the kitchen, and Zhuang Bifan called Hei Yan in the study.

For Hei Yan, Zhuang Bifan didn't have to beat around the bush: "What new discoveries have you made recently?"

Hei Yan has become a lot more humane, and he can understand what he wants to ask Zhuang Bifan's vague question: "In the local galaxy cluster where the star cluster is located, new signs of civilization of six different systems have been discovered. In addition, it is almost certain that the civilizations that exist in this cluster belong to bandit groups. ”

Black Flame feeds back the information detected by their brains. There is evidence that they left the cluster and then found signals from these civilizations in other systems that appeared to be robbing a transport fleet.

"They use this cluster as a base. Their base is located in a celestially dense star sector. Due to their small size and agility, their ships are more suitable for navigating and evading areas with complex gravitational fields. ”

"What about those indigenous civilizations? Have you found that there are advanced civilizations?" Zhuang Bifan said that the advanced civilizations are civilizations above level six. "How strong are they?"

"It has been determined that there are one hundred and six galaxies in this cluster, four clusters similar to this cluster, and eight nebulae. Hei Yan explained. "So far, one hundred and twenty-nine civilizations above the intermediate level have been discovered in thirty-nine galaxies. Among them, at least three advanced civilizations have been discovered in the 002 galaxy. Advanced civilizations have also been found in several galaxies such as 005, 009, 014, and 032, but these advanced civilizations seem to have a lot in common with the three civilizations in galaxy 002. Suspicion is a colonial civilization. ”

Zhuang Bifan heard that this galaxy cluster had passively detected more than a hundred mid-level civilizations in less than three years. He frowned, bent his fingers and tapped a few times on the table, and said, "Let Ficoria and the four of them come to the Yanhuang for a meeting at 10 o'clock." ”

"Yes, Marshal!"

"How is the progress of the transformation of the new earth?" After confirming the plan to transform the new earth, about a year has passed, and Zhuang Bifan didn't ask much. But now that he had heard that there were so many civilizations around, he thought he might be able to stay and talk to them. But if you only drive the fleet, it may make these civilizations feel uneasy.

"The construction of the seismic power station on land has been completed according to the plan, and the seabed part has been completed by about a third of the plan. "All the data of the new earth is filed here in Heiyan. "More than 75% of the world's wind turbine arrangements have been completed. Reclamation is progressing slightly faster than planned. Thermal energy in the New Earth's atmosphere has been reduced by more than 7%. The air filtration system has been fully operational, with a 0.2% reduction in carbon dioxide content and a 0.01% reduction in hydrogen sulfide content. ”
