The underground city plan has finally begun to fully launch, and engineering teams from various countries have rushed to construction sites in various places.
Prepare to build an extremely large-scale human survival underground city from all directions.
This project is easy to talk about, but after it is actually started, it will involve many problems.
First of all, according to the engineering drawings, the underground city will be set up five thousand meters underground, and it will be built into a large city with a population of more than one million.
Such large cities will be spread across every continent, so the difficulty can be imagined.
The most elite engineering teams from various countries rushed to Daxia and held a discussion meeting overnight.
Through this meeting, they will solve several crucial issues, which are related to whether the underground city can be successfully constructed.
Topography, engineering geological characteristics of rock and soil, hydrogeology, adverse geological processes, and the three-dimensional structure of the strata are all matters that need to be discussed and determined at this meeting.
So the meeting has been held and lasted for more than ten hours, but all the engineers showed no signs of fatigue on their faces, because they knew that what they were doing at this moment was a major plan related to the future destiny of mankind.
“If we were to build an underground city at a depth of five thousand meters underground, the balance of the core in the Earth’s core would be disturbed.
The impact passes through the Gutenberg discontinuity and affects the earth's veins, which is likely to cause geothermal volcanic eruptions on various continents, which is a fatal danger to human underground cities. "
“Yes, at the same time we are facing the problem that global seismic and magmatic activities are unavoidable.
After all the underground cities are established, it is likely that turbulent volcanoes will form and may erupt at any time.
Therefore, the materials used to build underground cities need to be taken extremely seriously. After comprehensive exploration by our scientific research team, perhaps only the many materials found in the remains of civilizations on the outer battlefields can achieve this effect. "
Engineers in the engineering team expressed their opinions one after another, and it was in this collision of opinions that a proper solution was finally formed.
In fact, humans have been exploring underground cities for a long time. People have discovered about thirty-six underground cities in the Turkish region.
Although these cities are just small cities, they are enough to show people that underground cities did exist a long time ago.
However, there is no precise definition of who built it, when it was built, and what its purpose was, and people often have different opinions on this.
Some people say that according to records, in the early days of Christianity, believers of this new religion came here in search of a place of refuge and established underground cities as a refuge.
Some people say that when war broke out in the second century AD, people who were devastated by the war established underground cities in the hope of avoiding the ravages of war.
However, none of these hypotheses have been confirmed, but for now, a lesson that can be given to everyone is that the foundation of this area is formed of tuff.
Because there are volcanoes nearby, as long as there is an obsidian foundation, it is very easy to be hollowed out.
So according to the original hypothesis of scientists, perhaps these early underground cities were hollowed out in less than a generation.
Most of these underground cities are three-dimensional buildings with more than thirteen floors. On the lowest floor, people even found artifacts from the Shaanmit era.
Based on this, engineers can also draw a hypothesis.
Unless it is built in a special place, it will take at least three years to dig out an ordinary foundation enough to open an underground city.
This is undoubtedly an adventure for the earth, which is already compact in time.
Everyone has to risk their lives and wealth to bet on the outcome of the underground city.
After a long period of discussion, engineering teams from various countries finally integrated a complete plan.
The underground city is no longer built based on each country, but with the twelve fairy palaces as the core.
In this way, using all the efforts of the whole country, only twelve underground cities need to be built. This is the most time-saving plan for the current earth.
As the vast engineering team drove into the area of the twelve palaces, it also meant that the vast underground city project was officially launched.
Rock engineering is not a one-time excavation that can be successful, but requires multiple excavations to complete. Due to the nonlinearity of rock materials, their stress states after being stressed are also completely different. The soil in each place is different. For the construction team, , the difficulty level will naturally vary.
Hence, for all the engineering pairs, their ordeal has just begun.
As for Daxia, the entrance to the underground city was chosen directly under Tianding Mountain.
The underground city here will also be the largest underground city in the world. Basically, every country in Asia will eventually take refuge in this underground city.
The underground city to be built at this time is not the kind of pseudo underground city used for tourism.
Therefore, scientists also have to consider energy issues. After all, the sun is our energy source. Light and heat can also allow plants to perform photosynthesis and animals to keep warm. Ultraviolet rays can also sterilize. Heat can provide water circulation. These They are all essential and important factors for human survival.
So the problem facing scientists is how to bring enough energy to survive in these underground cities. The plan is named Artificial Sun.
The efforts of all parties resulted in the rapid implementation of the underground city plan, which also caused the loud noises of construction to continue to be heard in the originally silent Twelve Immortals Palace.
Seven years is just a blink of an eye for the earth, but humans have to seize this limited time to create more future possibilities for themselves.
As a Dao Ancestor, Su Yun naturally learned of the news that the alien fleet was about to attack again.
After learning the news, Su Yun stood solemnly on the top of the mountain, overlooking the many practitioners in the Zenith Dojo below.
Looks like it’s time…
Su Yun secretly made a decision in his heart. A huge plan that had long taken root in his heart was now time to start implementing it.
During the last retreat, Su Yun was constantly improving this plan, which was to open up a world of practice.
This world of cultivation is like an independent secret realm existing on the earth. Generally speaking, according to Su Yun's vision, the extraordinary aura of this world will be very strong, and anyone can practice it.
This plan has been in Su Yun's mind for a long time, and he has been improving it through new insights and realms.
According to Su Yun's vision, once the world of spiritual practice is opened up, the future of mankind will no longer be vague.
When Zhao Guofeng learned that Su Yun had something big to do, he quickly notified Feng Jiwen, and Feng Jiwen did not hesitate to come to Tianding Mountain to meet Su Yun in person.
Facing Feng Jiwen’s doubts, Su Yun said word by word:
“Now that we have reached the final moment of mankind’s destiny, I also want to give mankind more hope of survival.
Since a long time ago, I have always had a plan in my heart, which is to open up an independent spiritual world and make the fate of the entire earth different. "
Feng Jiwen was naturally confused about this. He had no idea what Su Yun meant by the practice world.
In the world of spiritual practice, everyone can achieve twice the result with half the effort, and will no longer be restricted by bottlenecks. Everyone will have greater achievements than practicing on earth.
There are still many mysteries in this world of spiritual practice, but it is still too early to say anything about them at the moment.
I need an opportunity. Only by taking this opportunity can I have enough strength to open up the world of practice. For this, I need the cooperation of the Twelve Immortal Palaces and the cooperation of various countries. "
Although Feng Jiwen didn't fully understand what Su Yun was talking about, he quickly nodded and looked at Su Yun seriously and said:
“Don’t worry, Daozu, as long as you give the order, all countries on the earth will definitely cooperate vigorously!
I just don’t know when Daozu wants to create this miracle, and what should we do? "
Hearing this, Su Yun subconsciously looked back at the villa at the back of the mountain, and then said slowly:
“Wait a little longer, it won’t be too long…”
In Su Yun's heart, he was actually thinking about Xu Jiajia and the others.
In less than a month, the children will be born.
Everyone hopes to see Xu Jiajia and the children safe and sound, so that they can give it a go without any worries.
The idea of opening up a spiritual practice world is really too risky. Even Su Yun himself doesn’t know whether it will succeed or what risks he will face in the process.
But for the current earth, he had to try his best.
Human beings need hope. Underground cities are just passive refuges for human beings. The world of spiritual practice opened up is the infinite possibility for human beings to face many crises in the future.
Watching Su Yun's figure gradually disappearing at the end of the mountain road, Feng Jiwen stood on the top of the mountain with his hands behind his back, looking at the bright moon and stars above his head, he couldn't help but sigh:
“I hope mankind can survive this crisis, otherwise our demise will not evoke the slightest echo in this vast universe..."
Zhao Guofeng on the side also frowned and nodded in agreement:
"Do your best to fulfill your duties and obey the destiny of heaven, not to mention that we still have Taoist ancestors."
The two of them were talking and walking down the mountain. At this time, many dojos were as calm and leisurely as ever.
But this peace is more like the calm before the storm.
Seven years, the countdown begins today and has officially begun.
Twenty days later, Chen Jie and others were the first to be sent to the hospital, which was in line with the doctors' previous judgment.
Most of Xu Jiajia's childbirth dates were only a few days apart, so they were sent to the hospital together for recuperation.
The first person to be pushed into the delivery room was Chen Jie, who was also the first to be diagnosed with pregnancy. On the expected date of delivery, Chen Jie did show signs of giving birth as scheduled.
Su Yun, a father, was waiting in the corridor accompanied by Zhao Guofeng and others.
From beginning to end, Su Yun remained silent and stared at the closed door of the delivery room.
"Wow!"
As a loud cry was heard, the extraordinary aura above the hospital gathered here, presenting an extremely special celestial phenomenon.
In the east, the sky is surrounded by clouds of purple energy, showing an auspicious sign.
Among the purple auras, a golden and extraordinary aura was constantly surging towards the hospital.
Like meteors, streaking across the sky, seeming to bring new hope to people.
The purple air comes three thousand miles from the east, adding a touch of fairy air to the clear sky and white clouds.
There were thousands of purple clouds and thousands of auspicious colors, and all the foreigners in Daxia looked up in surprise.
The practitioners in various dojos worshiped towards the east with reverence.
That is the direction of auspiciousness. Purple air coming from the east is another sign of auspiciousness.
Under the current situation, everyone needs a hope to support them moving forward step by step.
Su Yun’s children have shown auspicious signs since their birth, which undoubtedly made more people believe that Su Yun’s descendants will bring new hope to mankind.
Many doctors stood curiously by the window and looked toward the east, with expressions of joy on their faces.
“Purple air coming from the east is a symbol of auspiciousness, and this child came to the world with auspiciousness!”
"The descendants of the Taoist ancestors are indeed extraordinary, and powerful people must be born differently!"
At the same time, more people discovered that the sky above the hospital was filled with colorful clouds, accompanied by golden sunlight, forming a fairyland-like picture.
All the flowers in the hospital suddenly bloomed, as if an invisible force had dispersed the mist, inexplicably giving rise to longing and hope for the future in everyone's hearts.
Soon, the doctor opened the door and walked out. Seeing this scene, Su Yun quickly stood up and walked forward.
“Taozu!”
The doctor said happily:
“The baby was born safely, it’s a boy!
This boy is very special. When he is reborn, there is an extraordinary aura surrounding him. This is an extraordinary son, and he will definitely have a good life. A man of great virtue will definitely have a long life! "
Hearing this, Su Yun felt relieved. The mother and son were safe, which was the best outcome for him.
Since the birth dates of the four of them were relatively close, Su Yun stayed in the hospital during this period.
When children are born, there are signs of purple energy coming from the east.
At the same time, with every move of the children, extraordinary auras gathered one after another. This phenomenon was very shocking.
Xu Jiajia and others also gave birth smoothly, and were later transferred to the same ward.
The sky showed a strange phenomenon that lasted for a long time. The purple clouds above the hospital stretched for thousands of miles, shocking everyone who saw it.
The dead flowers beside the window sills in the ward are blooming one after another. These visions are all caused by the birth of children.
Not long after the children were born, Zhao Guofeng, with Su Yun's consent, immediately contacted scientists to conduct a more detailed examination of the children... (End of this chapter)
