A year-long countdown in red appears on the big screen in the center of the dungeon.

When the countdown reaches zero, it will also be the end of the earth.

This is the last time for human beings to prepare, so all sides are working day and night.

Today's lunar ruins have been opened up to the 9th ruin, which is also the largest area and the largest number of hidden treasures among the ruins found by mankind so far.

Expeditions of more than 30 people have descended into the ruins, and each time they find an additional ruin, they may add a strong touch to the earth's defenses.

Nowadays, all practitioners are immersed in spiritual practice, so the state can also focus all its energy on technological innovation.

It's hard to make a big break in terms of weapon configuration in a short period of time, so exploring the ruins, getting as many resources as possible from them, and finding more clues about the aliens will also lay a great foundation for victory in this battle.

In the pitch-black ruins, an expedition team of 30 people spread out in a fan shape, and they all went deep together.

There are still many alien characters in the ruins here, and after these words were recorded, they were sent to the Lunar Scientific Research Center for the first time, and Zhang Keqi's student Li Weidong personally led the deciphering work.

It took two months to complete the investigation of the No. 9 ruins.

In addition to some of the energy substances that also exist in other ruins, it is worth noting that the expedition team has discovered a palm-sized, green glowing piece of unidentified matter on the 9th.

The substance was immediately sent to the Lunar Research Center, where scientists began to investigate.

However, in the course of the investigation, scientists also gradually realized the special features of the substance.

The first is that the substance emits a large amount of radiation every minute and every second, but scientists have not found a corresponding radiation for the radiation.

Therefore, it can be basically determined that the radiation radiation belongs to the existence outside of the earth's civilization, and at least for the time being, the earth's civilization has not yet discovered the existence of this substance.

In order to be able to more clearly determine what the reason for the existence of the substance in the remains is, scientists have made several repeated attempts.

By an unexpected coincidence, scientists have come to a startling conclusion.

At present, there are also many wrecks of alien warships sent from Earth for research in the Lunar Research Center.

Although the wreckage of these alien warships has been shattered, the outer layer still has an extremely strong energy barrier.

Scientists have tried countless ways to remove this barrier, but none have succeeded.

According to the data, it is speculated that the barrier is the main culprit for the difficulty of terrestrial weapons to cause damage to alien warships.

After all, extraterrestrial civilizations are untouchable on Earth, so scientists simply cannot understand why there are barriers on these wreckage.

There is no energy source to be found, and no energy core can be found, and the appearance of this barrier is inexplicable and even more strange.

However, when a scientist inadvertently put a piece of the researched wreckage back into the isolation vault for sealing, he accidentally walked past the unknown substance that emitted a faint green light, and unexpectedly found that the energy barrier on the wreckage had disappeared.

This discovery immediately led scientists to make a bold guess, and after many attempts, they finally determined that an unknown substance emitting green light could actually neutralize the energy barrier on the wreckage of an alien warship.

This news came out so timely, and scientists were worried that even if the Earth was tightly deployed, if it could not break through the barrier, it would be difficult to cause substantial damage to the alien warships.

But now the appearance of this substance proves that the barrier around the alien warship is not impossible to break, they just need to find the reason, and all the problems can be solved.

Li Weidong immediately passed the news to the earth, and Zhang Keqi and others were also very excited because of this news.

Elite scientific teams from more than 12 countries have entered the laboratory to sample material sent back from the moon and begin close analysis.

It is no exaggeration to say that this new discovery is enough to change the form of the battle, so all the scientists have fallen into an obsessive frenzy.

If the barrier of the alien warship can be solved, it means that the weapons of the earth can cause damage to the alien warship, at least this will greatly shorten the combat gap between the two sides.

Finally, the scientists spent several months on the experimental project.

Less than three months after the countdown on the big screen in the dungeon, a breakthrough has been made in the study of unidentified substances.

Scientists have named this unidentified substance Matter 0, which is also the most breakthrough substance that scientists have encountered in exploring the universe so far.

Most of the radiation emitted by this substance is gamma rays.

Gamma rays, which can effectively affect the energy barrier on alien warships.

This has led scientists to come up with a bold hypothesis that all the weapons equipped on the front line will be retracted and adjusted to have a gamma radiation effect.

Is it possible to damage the energy barrier of the alien warship like an unknown matter?

The idea was already presented at the conference and immediately attracted the attention of scientists from all walks of life.

There are more than 8 scientific research bases in the dungeon, and they have begun to try to achieve this goal.

However, in the end, it turned out that gamma rays were indeed capable of damaging the energy barrier of alien warships, and that the damage was corrosive.

In this way, if the weapon can be equipped with a device that can emit gamma rays, it will mean that the energy barrier of the alien warship will be useless to the earth.

Even though the alien battleship itself has extremely strong protection capabilities, at least every shell fired can accurately hit the alien battleship, not be resisted by the energy barrier.

With the latest conclusions, the scientists in the dungeon immediately reached a cooperation with the Lunar Research Base, and the two sides will work together to develop a weapon that can specifically deal with the energy barrier of alien warships.

With a new goal, people from all walks of life are busy again, and a new expedition team is once again going deep into the ruins, hoping to find more unidentified substances to add corresponding scientific research data to the experiment.

A month later, the Lunar Research Center finally developed a cannonball with gamma rays attached.

All Xuanwu fighters were urgently recalled and equipped with corresponding weapons and equipment.

By this moment, the Earth has officially completed all preparations for the preparation phase.

And the countdown time is already stretched thin, and the day of the big war is about to break out.

When there were three days left in the countdown, Feng Jiwen's voice spread throughout the entire dungeon and the moon base.

"Comrades, the alien warship has now reached the core detection area of the Sky Brain satellite, so even if they want to hide their figures, we can still capture the approximate location through signal reflection.

In three days, the alien warship will appear above Earth, which means that the battle we have been preparing for years is finally about to begin. ”

The moment they heard these words, everyone's expressions became solemn, even though they had made all the preparations they could, but when the battle came, they would inevitably feel a little panicked.

The outcome of this battle will determine the fate of humanity.

It was humanity that survived this catastrophe and became a rising star in the universe.

Or will it fall in the flames of war, and there will be no human beings in the universe again.

It was an adventure and a gamble with a hard time seeing the outcome, and all the people were in a solemn mood at this time, and the whole dungeon was enveloped in an oppressive atmosphere.

But Feng Jiwen's voice has always been neither humble nor arrogant, as the leader of today's human beings on the earth, the pressure on Feng Jiwen is unimaginable to ordinary people.

But at the same time, he also knows that if even he can't calmly face the upcoming battle, then maybe the people's hearts have been broken before this battle has even begun.

"Comrades, the earth has suddenly moved into the fast lane since it began, and the development of events has far exceeded our expectations.

Alien civilizations are eyeing us earth humans as ants, vainly trying to occupy the earth and use our lives to satisfy their experiments.

This is actually not uncommon in our long history.

Every country has been reborn from the flames of war after war, so I think our attitude towards the aggressor is the same.

Fight to the death and stick to every inch of land that belongs to us.

Alien civilizations, if they want to step on Earth, must step over our corpses. ”

Feng Jiwen's voice was sonorous and powerful, and it also revealed a strong battle intent.

This spirit is also influencing everyone, whether it is the people in the dungeon or the moon far away.

"Stand up, for the future of humanity, for our common destiny.

Even though the enemy is stronger than us, the determination to defend our homeland will be an unsurpassed force.

All the fighters, fully armed, armed and armed.

The major lines of defense set up in space will serve as the first line of human resistance against the invaders.

And the soldiers of various countries, you are our last line of defense.

Protecting all people is a belief that we need to carry out consistently.

The glory of mankind will last forever, and the flame of mankind will not be extinguished! ”

At this time, all the soldiers of the various countries had gathered in the main cities, and they were all armed and ready for battle.

Almost all of these soldiers are genetic, but at the moment they are also shouldering their responsibilities.

Behind them are hundreds of millions of people, and if it really comes to the last moment, they will resolutely go to the ground and build a high wall for all the people with their lives.

The preparation phase of the Earth is over, and the next thing is to wait for the battle to strike.

Three days were only in the blink of an eye, and the tense atmosphere gradually spread to every corner of the dungeon.

On the ground is a post-apocalyptic scene frozen for thousands of miles, but in the dungeon is a battle-spirited and battle-ready warrior.

Flags representing various countries have been raised in major cities.

But among them, the national flag of Great Xia is the highest and the most eye-catching.

After Feng Jiwen completed the pre-war mobilization, he immediately entered the joint conference room, and at this moment, the heads of state had already waited again.

In the ensuing battle, major operational orders will be communicated from the joint command room.

More than 24 satellites will comprehensively show the Earth the battle situation in space, so that the people in the dungeon can be ready to deal with it at any time.

At this critical juncture, all the cultivators still showed no signs of leaving.

But Feng Jiwen was not in a hurry, because he knew that even if the cultivators were out of the customs now, it would not be time for them to make a move.

The reason why the space defense line was set up was to consider that cultivators could not go into space alone like Dao Ancestor Su Yun and cause great damage to the battleship.

Therefore, the purpose of these space defense lines is to reduce the overall power of alien civilizations as much as possible.

As long as the cultivators can lend a helping hand in time after the aliens descend on Earth, the battle plan can be considered a complete success.

It can also be seen from this starting point that Feng Jiwen and others know very well that the alien front is not enough to resist the large-scale invasion of alien civilizations.

This battle is destined to be cruel, I don't know how many people will die here, but for the fate of mankind, in order to continue the human race, all the soldiers on the first line are resolute and die and come back to life.

Finally, what should come is always coming.

The mighty alien warships are constantly approaching the earth, and at this time, the commander-in-chief of the outer and outer planetary civilizations in the largest main ship can already see the figure of the blue and white planet.

Standing on the deck, there are alien warriors who have abandoned their bodies and turned themselves into mechanical organisms.

Dressed in armor and armed with the most elite weapons, they awaited the moment of aggression with great ambition.

Huge alien warships stretch as far as the eye can see, and a large number of cosmic beasts roar towards Earth.

"Didi......"

At 12:00 a.m. Earth time on the night of the third day, the Nantianmen platform took the lead in pressing the warning button.

Piercing sirens rang out in all corners of the earth, waking everyone in the dungeon from their slumber.

The people spontaneously came to the big screen, although they could not contribute to this battle, but how could anyone be absent from this battle related to the fate of mankind as a whole?

In the main city, the soldiers of various countries have already gathered, and they are all standing at the entrance of the main city to the ground.

Once the alien civilization breaks through all the defenses and enters the earth, they will go to the ground without hesitation, as the last resistance force of mankind, and fight to the death against the alien civilization.

They chanted in unison Feng Jiwen's last words.

"The glory of mankind will last forever, and the flame of mankind will never stop ......"
