Thirteen Earth years have passed in the blink of an eye. The fleet sent out to find the "Reaper" signal ship in www.biquge.info short period of time still hasn't found its target.

On the contrary, the new earth has completely changed.

Zhuang Bifan let the drugs used to promote the growth of trees into towering trees, which covered a large area of land. What was once a forest has become a temperate grassland, and what was once a desert area has become a savannah or even a lake and forest.

In general, the planet is not far from the Earth, and in some respects it is even better, except for its topography and size. At least, there is no air pollution already.

Zhuang Bifan could finally rest assured that he would take Sima Yun and land on the ground on this planet.

Although he felt that Zhuang Bifan was a little impatient, Sima Yun knew that this place would become his home in the future. When their aircraft landed in a subtropical climate zone that had evolved from a desert, Sima Yun found that there was no longer sand under his feet, but a thick layer of brown soil. The fertile soil above is the result of the vegetation on which it has been spawned and then decayed. The soil layer below is directly transformed from the desert.

Before landing, their aircraft flew around the land. After they fell to the ground, Zhuang Bifan took her by the hand, stood by the lake that had been eroded by the river, pointed to a vein that was looming in the distance and protruded from the plain, and said, "That mountain is by the lake, and there will be a dam a few kilometers upstream." What would you think of our home on it?"

Sima Yun let her hold her hand, looked at the big lake in front of her, looked at the green mountain, and said, "Didn't you let Hei Yan design the palace?

Zhuang Bifan smiled and said, "The first few mountains are the highest peaks of the mountain range. I'm going to flatten it below the average elevation of the mountains. That place is enough. ”

"It's like an earthquake zone. Although it is said that a large number of seismic power stations were built. But it is also possible to prevent just in case. Sima Yun really wanted to have a stable home, and she felt that it was inappropriate to build her home in an earthquake zone.

Zhuang Bifan said with a smile: "Before this place was renovated, there was an earthquake of magnitude 6 or higher almost five days later. At least one magnitude 7 earthquake occurs every month. After the construction of the seismic power station, there were hundreds of times more earthquakes here, but none of them exceeded the level three. ”

"But you're building a dam upstream. Once built, there will be an increase of thirty megatons of pressure. "The sudden increase in pressure in such a geological fault layer can be imagined as a result of the impact on the earth's crust. "The impact on geology is huge. ”

"You can rest assured, although it is true that there will be an earthquake hazard. But those seismic power stations were not built for nothing. No matter how much pressure is slowly released by the seismic power station, it will not accumulate pressure until the end before exploding. ”

He paused for a moment, smiled and said, "Speaking of which, the scenery of the waterfall upstream is actually very beautiful. But that waterfall has a lot of water, a big drop, and the noise is too high. ”

This is supposed to be a mixed area of plains and hills, and it is believed that there was an extrusion fault, and part of it formed a stepped plateau. It's like the North China Plain and the Loess Plateau. However, the altitude difference here is a bit large, the average altitude of the plateau is six or seven thousand meters, while the plain is less than five hundred meters. The plateau is also covered with snow-capped mountains, and to the south is a vast rainforest forest. A large river originates from this rainforest, absorbs countless tributaries in the middle, and finally drops from the plateau to the plain to form a super waterfall with a drop of 3,000 meters.

The rock formations have been eroded by the waterfall, forming a canyon with a depth of 3,000 to 6,000 meters. The width of the canyon ranges from more than ten kilometers to more than 300 kilometers, and it winds for more than 4,000 kilometers. The rivers in the canyon have a drop of more than three thousand meters in four thousand kilometers, and there are many rapids.

And because the climate of this great river has been transformed, the wind belt has changed, and now the water is more abundant. In order not to waste any resources, Zhuang Bifan planned to build a power station at the mouth of this canyon. It's just that the dam of this power station is a bit exaggerated.

The inner arch dam is designed to be 68 kilometers long, more than 3,300 meters high, nearly 6 kilometers wide foundation, and more than 3 kilometers at the widest point at the bottom of the dam, and 600 generating units with a power of more than 5 million kilowatts will be installed inside.

Electricity is a primitive energy source, but it is also an energy source, plus seismic generators, volcanic generators and wind turbines that are almost all over the planet. There are also hundreds of fusion generator sets that will provide energy for synchrotron rings outside of space.

In addition, the dam will provide irrigation water for tens of millions of square kilometers of agricultural areas. In fact, the need for irrigation water was the main reason he built the dam. Downstream of the dam there are large plains and hilly areas, and this relatively low altitude area only has convective rain in summer and autumn, and at least half of the year there is little rain and drought, and there is no irrigation water source for agriculture here.

In order to develop this galaxy cluster, there will definitely be more and more androids. And artificial humans also need to eat, so agriculture is essential. This is also the main reason why Zhuang Bifan allows people to develop planets. The new earth is a planet that is naturally suitable for the development of agriculture, and he certainly cannot waste it.

And the native large animals of this planet are basically extinct due to the sudden change in climate, and many plants have also become extinct. He was able to allow the genetics brought from Earth to breed new creatures to settle on this planet. In addition, he plans to merge the genes of indigenous organisms with those of the earth to create some new organisms. After all, some of the animals on this planet are larger than Earth's flesh animals.

Sima Yun glanced at him, then at the hazy mountain range, and said, "It's too noisy over there at the waterfall. It's better to be there. She said, gesturing to the mountains.

"If that mountain is leveled, it can create more than 100 square kilometers of flat land. And the mountains can provide groundwater. Zhuang Bifan said with a smile.

Sima Yun didn't think about this: "There seem to be hills under that mountain range, and there are some mountains and rivers, and we can usually go to those places to play." And the climate in the mountains is better. ”

Zhuang Bifan thought about it for a while and felt that it was the same. He smiled and said, "Then I'll let Hei Yan design some gardens." ”

Sima Yun's eyes lit up and said, "You can copy some gardens of the Chinese Empire." ”

Zhuang Bifan sighed slightly in her heart, knowing that she still couldn't let go of the earth in her heart. He put his hand around her waist, leaned her into his arms, and said, "It's up to you!" He thought of building some buildings in another world republic, such as the southern gardens of Suzhou and Hangzhou, as well as the mansions and even palaces in the north. Although he couldn't remember the details, he still remembered the general layout. Let Hei Yan refer to the design, and he can also have seven or eight points of image.

Sima Yun smiled and said, "That's the best." In the future, this planet will only live by ourselves, and it will be a little lonely in the end. It shouldn't be boring to have a place like that to play. She looked at him and said. "When we have children in the future, taking them to those places to play can also let them feel the development of our human civilization. ”

Zhuang Bifan also thought about this problem, but he had never settled down before, so he didn't think about having children. Even now, he still hasn't really felt secure.

He was anxious to transform the new earth, but he wanted to reassure Sima Yun, and at the same time find a reason for himself to fight with that reaper force.

Now he faced an enemy that was probably far more powerful than any enemy he had faced before. The unknown source of power has never been found, though the enemy has never appeared. But Koster was right. The later the enemy appears, the stronger the enemy is likely to be.

The more he learned about the Reaper from Koster's mouth, the more he wavered in his heart.

He may have been able to deal with the Reaper once, twice, or even three times by mysteriousness. But when his strength is fully revealed, the Reapers, with all their might, will go all out to eliminate him. Because the Reapers, there is no possibility of threatening their existence. Know that the Reapers, not only are they militarily powerful, but they are also very powerful.

After Hei Yan learned about the Reaper, he basically determined that the unknown enemy who exterminated the Three-Eyed Civilization was most likely the Reaper, but he didn't know if it was the same as what they were about to face.

The military power of the Three-Eyed Civilization back then was not much worse than that of his current one. But the Three-Eyed Civilization was eventually destroyed.

Now he looks very strong, but according to Koester, if the Reaper comes out to deal with him, he really doesn't have much confidence to be able to bear it. Even if we are now accumulating strength at full speed, the war with the Reapers is imminent, and time is running out. Unless Black Flame can connect to Black Flame Space as soon as possible, and use the resources and productivity there to send warships over.

But whether he can connect to the Black Flame Space is still a matter of words. Besides, if you want to connect, the Yanhuang can't move in a large area. Because the more times you move, the larger the range, the greater the coordinate error. Of course, the more difficult the calculation becomes.

He even thought about giving up reconnecting with the Black Flame Space forever and escaping this galaxy cluster. But he listened to Koster's persuasion: "Our existence has been exposed. The range of eyes and ears of the Reaper is large. Even if we are willing to run away, we may never be able to settle down. ”

It was one of the reasons to keep him here, but it wasn't enough to keep him committed. He also needed to find a reason for himself: home.

So he took great pains to transform the new earth in the shortest possible time, in order to find a home for himself.

But at this time, Sima Yun suddenly raised the child's question, which also made him a little stunned.

Child, he is not unwanted. He didn't want his children to face that kind of threat. Moreover, Sima Yun's theoretical lifespan also has hundreds of thousands of earth years, and there are still many opportunities to have children.

He groaned for a moment and said, "We are still young. Wait until we really settle down to have children. "Only if they defeat the Reaper will he consider having a child with Sima Yun.

Sima Yun blinked and said with a smile, "Okay." She could feel that Zhuang Bifan had been a little uneasy recently. It's just that Zhuang Bifan refuses to say. She didn't ask any more questions. However, she could feel that Zhuang Bifan was desperate to give her a stable nest. The two have been together for a total of "hundreds of years", and Zhuang Bifan has lived for "more than 2,000 years", and he has not changed his mind before, and she believes that he will not in the future.

Since that was the case, she had nothing to worry about.
