The three-month trip to the Earth World is impossible to achieve without a teleportation array, and the time on the road alone is more than enough.

Neptune is very far from the sun and the temperature here is very low. If ordinary people don’t have space suits, they can instantly freeze into ice.

Even practitioners with lower cultivation levels of the Transcendental Level will not last for a few minutes. Only the super-level powerful people can barely survive here, because they can fast, eat, suck, and air. As long as there is energy everywhere in the universe, they can maintain vitality.

But it still cannot last long. Spiritual loneliness alone can drive people crazy.

Fortunately, Neptune had built the Space City last year, where there are more than 10,000 practitioners and service personnel, maintenance personnel and entertainment projects, so they will not be lonely.

From time to time, you can enter Neptune to practice. Zhang Xiaohuan's trip is in the ice and snow world of Neptune. In fact, there is no snow, it just describes its coldness.

In the blink of an eye, another half month passed, and Zhang Xiaohuan left here with a hint of joy and headed for the last stop, the Great Wall of Stars.

"People, I haven't seen you for half a month. Do you miss me?" Zhang Xiaohuan's little face, which looked much white, suddenly appeared in the live broadcast room.

"Huh? Where did Xiaohuan do maintenance? It's a lot whiter, but why does her skin feel a little bad?" someone joked.

"Well, I've gotten a lot white. I guess in another half a year, the fair-skinned and beautiful goddess Huan will be back."

"Oh, are you all the attention wrong? Look behind Xiaohuan." Someone reminded.

"My grass is so spectacular, what is that?" Someone was shocked.

"Xiaohuan, what's behind you? It's too grand and incredible, right?"

Zhang Xiaohuan smiled slightly, and she knew that everyone would be like this. Even the other end, they were surprised to have their expressions, because she was shocked when she saw it, and could not be described in words.

"Please see, this is the Great Wall of Stars built by our country. The purpose of building the Kuiper Belt is to protect the solar system." Zhang Xiaohuan said.

I saw an endless black Great Wall spreading along the surface of the Kuiper Belt, and countless robots could be seen working, indicating that the Great Wall has not been completely completed.

"Do you know about this Great Wall?" Zhang Xiaohuan asked.

"I really asked this, I really don't know?"

"I, Bai Xiaosheng, said that the Great Wall has only been known and has no information, because it has never been published to the public. There are only a few photos circulating on the Internet. It is not as clear as your live broadcast as Xiaohuan."

"By the way, will Xiaohuan have any problems with the live broadcast now? We will not invite us to have tea when we see it, right?"

"What are you thinking? How can we, Guo Jia, be so enlightened? And since Xiaohuan can broadcast live, it means there is a signal here, and no one comes to expel it, which means it is no longer absolutely confidential. Everyone should not worry, just feel free to appreciate this spectacular."

"It is definitely the greatest miracle of the twenty-first century, and no architecture can compare to it, including Space City."

"By the way, what Great Wall is built here? There are many asteroids in the Kuiper belt, which are a good defensive barrier. Isn't it a waste to build the Great Wall?"

"Yes, I'm not sure. Moreover, the universe is four-dimensional. What's the use of this Great Wall? Is it possible to build a sphere to wrap the entire solar system inside? That's simply a fantasy and it's impossible to achieve."

Many people wonder why Guo Jia spent a huge amount of money to build the Great Wall of Stars.

"Xiaohuan, you are a top student at Xianyuan University. Do you know the reason?" Someone thought of Zhang Xiaohuan.

Zhang Xiaohuan was stunned for a moment and nodded: "Our teacher has indeed talked about some of this, so I won't talk about the details. I don't understand the specific principles very well. I will tell you about the role of this Great Wall."

"The Great Wall has four major functions and countless small benefits. I won't go into details. I will talk about these four major functions. You will know the power of the Great Wall, which is also the reason why we Guo Jia had to build it at all costs."

"First: The Great Wall of Star itself is a spirit gathering array. Once the Great Wall of Star is built, this super huge spirit gathering array can be formed. At that time, it can quickly absorb a large number of high-energy particles from outside the solar system and enter the solar system. At that time, the practice environment in the solar system will be better."

The dark matter particles and high-energy particles that are everywhere in the universe are still uncapable even with current technological means.

However, when practicing, you can mobilize them to your surroundings for practitioners to absorb.

On the same principle, the formation also has this function. Once the formation is completed, it will absorb all the surrounding high-energy particles like a black hole and lock them within the solar system. In this way, the concentration of high-energy particles in the solar system will be increased, and the cultivation environment will be invisibly improved.

Hao Renzhen has tried his best to make the earthlings. After all, he doesn't need it at all. He usually practices in the Time Tower.

"Second: It can isolate the breath. Once it is built, the breath of Xuanhuang Realm will be hidden. Although we have never come into contact with real aliens, the principal said that through the civilization fortress, we can be sure that there are countless civilizations in the universe, and there are many intelligent civilizations in the Milky Way alone. We don't know their strength, and we don't know their attitude towards other civilizations. The best way is to make ourselves stronger as much as possible and then face them."

Civilization Fortress prohibits civilized struggles with the universe, but the universe is different. If you drive a spaceship and people want to conquer you, the Civilization Fortress will not be able to control it.

Now that the Earth Civilization Fortress has appeared and has passed the novice period, theories of the civilizations that have civilization fortresses in the Milky Way have known that a new intelligent civilization has emerged in the corner of the Milky Way and has also controlled the civilization fortress.

It’s just that they don’t know the level of the Earth Civilization Fortress.

Hao Ren never underestimated others, would not think that those civilizations that had controlled the civilization fortress a long time ago on Earth would be weak, and would not think that they were very kind, so the necessary preparations still need to be made.
