"The world changes."

"It's really a world of change. Unexpectedly, we humans have such amazing power now." Tang Zhengming kept sighing, and Chen Kangwen looked helpless, making everyone laugh.

As time passed, the collapse of the blue-black celestial bodies finally reached a limit, and the ejected magma also cooled extremely quickly. The biological tissues that constituted the celestial bodies in the blue-black celestial bodies changed rapidly at the same time, from active state to rapid hardening, the surface gradually changed color, the color began to become shiny, and gradually began to change to grayish white.

Gradually, a planet with a bumpy surface that seemed to hit countless asteroids appeared in front of everyone again.

Man-made moon, finished.

It was not just Cheng Xiang and others who followed this scene.

Just when this artificial celestial body was formed, it attracted countless attention. Not only the Chinese, but also other countries on the earth watched this magical scene happen on the earth.

Three years ago, the moon was gone.

Three years later, the Chinese recreated a moon.

When the new moon completely calmed down, the various parameters of the new moon were no different from the previous moon.

This scene shocked the countries on Earth. They looked at the moon with astronomical telescopes, but those who had no conditions could only look at the satellites of their respective observatories.

Seeing the moon that was shattered in the past, now hanging in the air again, the absurd feeling was shaking from the equine tail bone.

"The Chinese country is too powerful."

"Don't shit, if this continues, the entire solar system will almost become a Chinese country."

"Thinking back then, our country had the sweetest air in the world. We were the first to land on the moon and on Mars in the world."

"But now, China is more powerful than us. If it weren't for the limited population, it would probably be the entire solar system of China."

"Pity our space plan has been around for decades and is still on recyclable rockets. The spacecraft launched last time is no better than that. In this comparison, China is a young man, and our spacecraft is no different from the 90-year-old grandma. Oh, when will we really sail freely in the solar system?"

"Don't think about it. It is said that top scientists have already gone to China. I heard that many of them were kidnapped directly by people above. The top scientists are gone, and they are still in space. Let's dream..."

...

The moon is re-constructed, and this ceremony is over.

Cheng Xiang and Zhao Xue looked at each other and said goodbye to everyone. After taking a separate spacecraft, they began their honeymoon trip that they had landed two years ago.

Although Cheng Xiang's personal spacecraft is only used by family, it is not small at all, with a diameter of 500 meters. It was not so big on the earth before. Therefore, there are all facilities inside.

After the spacecraft left the mothership, it immediately accepted the unified command and dispatch of the Earth and Moon Tower. The spacecraft began to circumnavigate and look at the earth from space. This feeling was very unique. In the past, only astronauts could come to space. Now, it is already very ordinary for Chinese people.

Although private spacecraft has not been opened to individuals, many space tourism projects have been opened, and tourism companies can rent spacecraft and conduct tourism activities.

Since the project was opened, almost every holiday or holiday, a large number of Chinese citizens have conducted space travel.

"Look, the new Great Wall."

"So spectacular." Zhao Xue exclaimed.

Cheng Xiang smiled.

The New Great Wall is a city wall built by biotechnology that stretches around the entire border of China.

The city wall is nine thousand meters high and one kilometer wide. Such a towering and majestic city wall, not to mention the emergency weapons inside, can be said to be a place where there is no way to cross the sky and no way to enter the ground, and it eliminates all the thoughts of trying to smuggle people.

At the same time, in China, the once steel bricks and tiles have long disappeared, and emerging cities built on biotechnology have already spread all over China.

"Look at Brother Cheng, Sky City! Sure enough, it looks more beautiful in space."

"It should be the Star City Elf World." Zhao Xue kept chattering, and Cheng Xiang also felt the long-lost relaxation.

...

The spacecraft quickly circled the earth for a while. After the orbiting, the spacecraft did not return to the mothership, but instead sailed towards the sun quickly.

"Brother Cheng, aren't we going back?" Zhao Xue was a little confused.

"Girl, I haven't had time to spend the past few years with you. This time we'll have a good time to go and see the changes at the moment." Cheng Xiang said as he tightened his arms. Zhao Xue felt that she was about to melt. Her big eyes narrowed like a lazy cat, and she was just next to Cheng Xiang.

Only when the spacecraft breaks out of the earth's orbit can it truly feel the prosperity of space today.

Nowadays, every 200,000 kilometers, there is a space port on the orbit. This space port is similar to the previous gas stations on land, but the space port has more functions.

In addition to being responsible for piloting spacecraft, planning routes, providing berthing ports, replenishing fuel and material supplies, the network is also paved by these airports.

Along the way, there are not too many spaceships coming and going.

At this time, the number of spacecraft of volume like Cheng Xiang is not large in the solar system, but more are those heavyweight large spacecraft.

Especially Mercury, Venus, Earth and Mars orbits, there are large cargo spacecraft busy back and forth everywhere. In terms of volume, they start at least 30 kilometers, with the largest diameter reaching a level of 100 kilometers.

Although larger spacecraft can be manufactured, its cost-effectiveness is not high. The larger the volume, the greater the impact of gravity, and the more other factors are affected. It has to be said that both mechanical technology and biotechnology, materials and energy are important cornerstones that limit the development of civilization.

In a blink of an eye, more than a dozen hours passed and the spacecraft had arrived near the orbit of Mercury.

Standing in the starry sky near Mercury, looking at the sun again, the sun is already eight times larger than on Earth.

If it weren't for the panoramic system filtering, it would be impossible to look directly at the sun at this time. The red color and burning fireballs were the real power of nature.

Under this hot light, Mercury has a huge temperature difference between day and night, with a total of hundreds of degrees Celsius, which is a very bad living environment for humans. But now, it is an excellent production base.

In the past, Mercury and Venus had a harsh environment. Even when the space race was at its peak, I didn’t think about considering these two planets. But now, Mercury Venus has become an important production base in China in just two years.

Previously, there was nothing outside the Venus orbit, but now, there was a huge artificial celestial body above the Venus orbit. The spherical artificial celestial body directly connected to the surface of Venus through a biological elevator, responsible for the transportation of materials in space and the ground. From a distance, countless spacecraft took off and landed at the port.

"Wake up, girl, we're at Mercury."

"Ah, it's time for Mercury."

Yesterday, the two of them were moving under the holographic scene in space for the first time. There was a unique flavor in the starry sky. Even with Zhao Xue's physique that has been strengthened several times, she now feels very tired.

If you miss Venus, Mercury can't be missed no matter what.

Wearing a tulle and looking at Mercury that was so close to her, Zhao Xue stared at everything in front of her.

"What a big port, is that Mercury's ladder and port?" Zhao Xue exclaimed.

Cheng Xiang smiled when he heard this, "This must be big. On the earth, in order to protect the ecology, we have almost stopped mining. This place is close to the sun and sufficient material energy, and is our largest production base now."
