In the following year, the whole world was working hard to develop underground city projects. Although the progress was slow, it never stopped.

The practitioners have never stopped practicing. According to statistics from the Bureau of Culture and Dao, the number of practitioners who have entered the fourth realm this year has reached several million.

 Many of them have begun to stabilize the fifth realm.

Practitioners who have reached the middle stage of the fourth realm can easily reach the peak of the fourth realm by taking the mysterious fruits found in the supernatural realm, and can even use this power to attack the fifth realm.

Feng Jiwen disclosed this information to the heads of state, which also doubled the confidence of various countries. This means that the earth has one more chance of winning when disaster strikes.

On this day, Zhang Keqi was still on Earth as the commander-in-chief, directing the team to mine and explore the lunar ruins.

Since the formation of a signal interaction platform between the earth and the moon, zero-delay and barrier-free communication between the earth and the moon has been completely achieved.

In this way, Zhang Keqi only needs to sit in the general command room to be able to grasp the situation of the lunar ruins at any time and provide the most powerful help to the representatives.

It is precisely because of this that teams from various countries were able to complete the research and exploration of the fourth ruins in a short period of time and begin to attack the fifth ruins.

　　During this period, the earth also gained a lot, including energy crystals capable of supporting an artificial sun and various unprecedented alien technological debris.

This has allowed the most elite scientists in the building to join forces with scientific teams from various countries to carry out non-stop research day and night.

Through the discovery of liquid guard scientists, the core technology for making this liquid guard is a kind of nano-form interaction.

 Such technology does not currently exist on the earth, but such a discovery can help the earth to carry out research and development of nano-form interaction technology.

Before that, Zhang Keqi personally led the scientific research team to conquer the core program inside Liquid Guard and injected it into the computing model of Tiannao satellite.

In this way, the earth will have the ability to control fluid protection, which can be regarded as adding a technological defense force to the earth.

“Turn right on the fork in front, and after dodging three laser rays, there is a door leading to the main control room…”

 Zhang Keqi calmly directed all the teams through a satellite-simulated road map.

Members of the national teams also followed Zhang Keqi’s command in tacit understanding and continued to go deep into the ruins.

 Different ruins have completely different levels of danger. If the representative does not have a trustworthy technological support behind him, it may be difficult for anyone to penetrate deep into the hinterland of the ruins unharmed, let alone bring back any useful materials from inside.

Zhang Keqi also knows the heavy responsibility he bears. On his shoulders, he carries the lives of many members of the representative team.

Hence, he ordered all scientific researchers not to disturb him at will during this process.

 Unless an extremely urgent situation occurs, he must wait until he has completed his command actions before allowing other people to interrupt him.

What Zhang Keqi didn't expect was that there was a rush of footsteps in the corridor, and then the door to the main control room was violently pushed open.

 The loud noise coming from behind made Zhang Keqi feel a little confused. He looked back in surprise, only to realize that the person walking into Wuzhong was the most capable person in his scientific team, Liu Yuyang.

Liu Yuyang is in his 40s this year. Among senior scientists, he is considered very young for his age.

In Zhang Keqi's impression, Liu Yuyang has always been a very calm person, but a rare anxiety appeared on his face during the vocabulary class.

This made Zhang Keqi realize that something big might have happened even before Liu Yuyang opened his mouth.

 He quickly pressed the silence button, then looked at Liu Yuyang and asked:

“Professor Liu, what happened?”

Liu Yuyang subconsciously wiped the sweat from his forehead, then walked quickly to Zhang Keqi's side, lowered his voice and said:

“The alien fleet entered the solar system 10 minutes ago.”

Hearing this, Zhang Keqi's heart suddenly trembled. He had expected that this day would come, but at the moment when he actually learned the news, Zhang Keqi still felt a little flustered.

But Zhang Keqi soon noticed that Liu Yuyang seemed to be hesitant to speak.

“Professor Zhang, after the alien fleet entered the solar system 10 minutes ago, it did not continue towards the earth as we imagined, but instead stayed at the edge of the solar system.

However, the Tiannao satellite detected that an extremely powerful energy began to accumulate around the alien fleet, but it was unable to know what the alien fleet wanted to do. "

At this moment, Zhang Keqi finally understood why Liu Yuyang was so solemn.

Any unknown nature that appears on the enemy is enough to cause unimaginable disasters to the earth.

So after a brief thought, Zhang Keqi quickly issued an order, ordering all the teams to temporarily stop exploring and researching the ruins, while he quickly followed Liu Yuyang towards another monitoring center.

Since the scientific team has been constantly updating the technology of the Tiannao satellite over the years, the monitoring range of the Tiannao satellite can now completely cover the solar system. This allows the enemy to be immediately detected by the Tiannao satellite the moment it enters the edge of the solar system.

Of course, this is also because the alien fleet obviously has no intention of hiding itself. Otherwise, the technological disparity would completely allow the alien fleet to enter the earth without being noticed.

Looking at the simulation images returned from the Tiandao satellite, Zhang Keqi also felt a little confused. The alien fleet had actually entered the solar system. Why did it stop at the edge of the solar system instead of continuing its operations?

 What exactly are they planning to do? And what is the power that is constantly accumulating?

 Zhang Keqi quickly began to direct the technical staff present to analyze the ongoing internal forces.

But as far as the people in contact can make after half an hour, this force is the dark matter energy that has always existed in the universe.

The alien fleet has obviously mastered the technology to control dark matter energy, but what will this dark matter energy bring? No one knows, and the purpose of the alien fleet is unknown.

 After thinking for a moment, Zhang Keqi quickly reported the matter to Feng Jiwen.

 Feng Jiwen also immediately convened a joint meeting of heads of state.

  But regarding this strange situation, heads of state are also confused about it.

Humanity’s understanding of dark matter is very minimal, let alone using it to deduce what the alien fleet wants to do.

As a last resort, Zhang Keqi could only order all technical personnel to monitor the dynamics of the alien fleet 24 hours a day.

And he and the most elite team of scientists from various countries began to fundamentally understand dark matter, hoping to gain early insight into the purpose of the alien fleet.

But obviously, the alien fleet did not intend to give the earth such preparation time. On the night when it was discovered that the alien fleet was accumulating energy at the edge of the solar system, a new situation emerged again.

 Zhang Keqi is connecting with elite scientific teams across the country in the conference room to discuss the existence of dark matter and its possible impacts.

But then the entire building was invaded by a piercing siren. The moment he heard the siren, Zhang Keqi rushed to the command room in a hurry, only to find that all the technicians had a bit of panic on their faces.

“Professor Zhang, after the alien fleet accumulated dark matter energy to a certain base, it launched this energy.

 This energy is now approaching the Earth at an extremely high speed and is expected to arrive at the Earth in two days. "

Zhang Keqi gritted his teeth secretly. He didn't expect that all this would happen so quickly, and he didn't even have any time to prepare.

The lights in the command center were brightly lit that night. Zhang Keqi's scientific research team, together with elite teams from all over the world, quickly began to try to track and analyze this energy.

 During this night, scientists from various countries put forward hundreds of guesses, and eliminated them one by one during joint discussions. Finally, they finally determined the only guess that might be consistent with the current situation.

“Once a large amount of dark matter energy is injected into the earth, it will quickly change the earth’s original energy field.

 When the energy field is damaged, it is likely to trigger a series of extreme reactions on the earth, such as abnormal weather, increased power of tidal changes, and a series of unpredictable situations. "

After this speculation was put forward, it was gradually recognized by scientists from various countries. Some scientific teams even started simulations directly on computers. The final result was that the probability that dark matter will cause extreme weather on the earth is as high as 98%.

 After getting such a result, Zhang Keqi sat on his chair absentmindedly. Now he finally roughly guessed what kind of plan the alien fleet was making.

They intend to use the natural forces existing on the earth to completely collapse the resistance on the earth without spending a single soldier.

 This approach is not cruel, but from a military perspective, it is the most advantageous method.

In this case, doesn’t it mean that before the arrival of the alien fleet, the first thing humans have to face is the extreme environment that appears on the earth.

Within an hour after this speculation emerged, heads of state learned the news from Feng Jiwen.

Everyone was a little confused at this moment, and they all looked at Feng Jiwen, hoping to get an effective solution from him.

Feng Jiwen lived up to expectations. Under such an urgent situation, he quickly made a difficult decision. Even though the underground city has not been fully completed, the basic survival needs have been guaranteed.

 Before dark matter energy is injected into the earth in two days and triggers a large-scale disaster on the earth, all humans must move into underground cities during this period, otherwise this will be a devastating disaster for mankind.

　In this ordinary night, piercing sirens sounded in various countries.

 Local military and police stations in various countries have been dispatched one after another and informed the public through various means what is happening now.

All underground city entrance doors were opened one after another. With the intervention of national power, people from all over the world quickly rushed to the nearest underground city entrance, preparing to take the lead in entering the underground city to take refuge.

 Such emergencies completely broke the earliest arrangements of various countries. All the people were confused at the moment. Some were suddenly told that they had to be transferred to the underground city urgently while some were still sleeping. No personal property was allowed to be taken.

 For the country, the lives of the people are a big deal, so they must race against time to complete the transportation to everyone on the earth within two days.

Just thinking about how huge this project is, all the main routes leading to the underground city were suddenly overcrowded.

Helicopters are constantly transporting civilians in the sky, and armed forces can be seen everywhere on the roads protecting civilians.

At this moment, all countries are caught in an urgent situation. In contrast, Daxia has a completely different look.

The directors of the Taoist Hearing and Taoism Bureau from all over the country went to the local area one after another to inform all the practitioners about the severe weather that the earth will encounter in two days.

But all the practitioners expressed their unwillingness to leave the ashram, and they did not want to give up their practice plans because of this.

This may be the most fundamental purpose of the alien fleet. When people are overwhelmed by natural disasters, it is naturally impossible to formulate a perfect defense plan. As a result, after the alien fleet actually arrives, mankind will be completely passive. .

 The directors of the Wen Dao Bureau saw their determination from the attitude of the practitioners.

 But no one knows what kind of bad weather the earth will encounter. No one knows what kind of disaster the dark matter will cause after it reaches the earth.

 In this case, preserving all the existing practitioners is naturally the top priority.

Hence, it was heard that the bureau chiefs from various places were advising all the practitioners to enter the underground city to take refuge together, but the practitioners firmly stated that Daozu would not ignore this.

 And they will firmly follow the steps of Daozu, no matter what decision Daozu makes, they will follow them to the death.

　　Hearing the news, Feng Jiwen frowned.

Why didn't he want to hear what Su Yun meant under this situation? But Su Yun was in seclusion at the moment. Who knew when he would come out?

 For this matter, Zhao Guofeng was even driven out of the transcendent realm.

Since the current transcendent realm is not large enough to accommodate all practitioners, it cannot be used as a refuge for all practitioners for the time being.

He specially took a helicopter to Tianding Mountain and stayed outside Su Yun's retreat, hoping that Su Yun could leave the retreat as soon as possible.

 But he actually knew in his heart that Su Yun did not know what was happening in the outside world, and he was afraid that he would not be able to provide any help in the disaster that the earth was about to encounter.

 All the practitioners are also looking forward to Su Yun being able to guide everyone in a direction at this critical moment... (End of this chapter)
