"Faster-than-light flight?" Ning Shuangshuang asked in surprise, "Is there really a faster speed of light?" Can a fourth-level civilization do it? Isn't the speed of light the maximum speed in the universe? Is it true that what is written in science fiction? ”

"Oh, this faster-than-light is not that the real speed of the object reaches the superluminal speed, but that the theory of space folding acceleration is used to form a kind of warp space bubble, which wraps the spaceship or fleet from point A to point B in space, and it seems to achieve a faster-than-light effect."

Du Qiu briefly explained the basic principles of faster-than-light flight.

Ning Shuangshuang blinked his eyes wide, and asked again: "Now that you have figured out the principle, when will we be able to build such a battleship that flies faster than the speed of light?" ”

Du Qiu took Ning Shuangshuang's hand and said: "Although the principle is clear, there will be two problems in practical application, one is the force field control device that folds the space to form a curvature space bubble.

And then there's the energy, and the amount of energy needed to fold the space is amazing.

With our current science and technology, neither of these has yet made a final breakthrough. ”

Ning Shuang's eyes were at Du Qiu, why did this guy like to hold his hand so much.

"Du Qiu, if this alien civilization had the ability to travel faster than the speed of light, I think they would have come to the solar system a long time ago, instead of hovering 3 light years outside the solar system, but sent a probe spacecraft to simulate meteorites entering the solar system and conduct reconnaissance activities."

Du Qiu patted his forehead and said, "You're right, if they have a fourth-level civilization, they can definitely break into the solar system directly. ”

Speaking of this, he suddenly thought of something, and shook his head again: "No, our solar system is probably different, they may be worried about something, so they sent a meteorite spacecraft to investigate first." ”

"Different?" Ning Shuangshuang looked at Du Qiu with a puzzled expression.

"Yes." Du Qiu said, "We have found a signal filter left by the Pleiades civilization on Mars, and we speculate that when the Pleiades civilization left, it did some kind of signal shielding for our solar system.

Look at the cautious appearance of this alien civilization today, and maybe there are ways to prevent other alien civilizations from peeping into it that we don't know about.

Perhaps this is the reason why a fleet of a fourth-level civilization does not dare to act rashly, after all, the Pleiades civilization may be the existence of a fifth-level civilization. ”

Speaking of this, Du Qiu's face changed again, "It's not good, that alien civilization outside the solar system won't treat our solar system as a treasure of fifth-level civilization relics, right?" ”

Ning Shuangshuang listened to Du Qiu's inference, looked at Du Qiu's sad face, although he was also worried in his heart, he comforted: "Du Qiu, don't scare yourself, what if they are a third-level civilization fleet?"

I think that if you are not at ease, the Celestial Realm has basically completed the power transformation, and you can arrange for the Celestial Realm to leave the solar system now.

Regardless of whether they are a fourth-level civilization or not, how far we can run, how far we can run first, and if the people we stay behind win the battle, we can also let the Heavenly Realm fly back. ”

Du Qiu looked at Ning Shuangshuang and nodded slowly, "You're right, now I ask you to immediately lead the Heavenly Realm to carry out the evacuation plan!" ”

Before his retreat, he had already made an evacuation plan and prepared for it, and now he just needs to follow the plan.

Ning Shuangshuang retorted almost immediately, "No, it's better for you to leave with the Heavenly Realm, and I'll stay behind to command and block the attack." You are the soul of the company's science and technology, and you can quickly improve our scientific and technological level. ”

Du Qiu shook his head and said, "You are wrong, if you want to effectively block the enemy, you need to complete the three technologies I just broke through in the shortest possible time.

If I am not there, it will be difficult to ensure that these three technologies are fully completed, then naturally I will not be able to stop the enemy's attack, and the Heavenly Realm may not be able to escape. ”

Seeing that Ning Shuangshuang was still trying to persuade her, Du Qiu held her down, "Shuangshuang, now is not the time for you and me to argue with each other, listen to me and immediately implement the Heavenly Realm evacuation plan!"

I'll move my command to Mars and deal with the intruding enemy to buy you enough time to leave.

Remember, you have the responsibility of passing on the Blue Star civilization, and forgive me for entrusting you with such a heavy burden. ”

"Is it true that you are the only one who stays to complete these three technologies?"

"Yes, if it weren't for that, I would definitely evacuate with you!"

Ning Shuangshuang looked at Du Qiu's resolute face, and didn't know what to say for a while, Du Qiu's meaning was obviously that only by completing the three technologies that had just broken through could they play a role in blocking the alien enemy.

"Okay, but I want you to promise me that when you complete the three scientific research and development, you must also carry out the evacuation, and I will wait for you to catch up!"

In Ning Shuangshuang's view, Du Qiu plays an irreplaceable role in the future development of human science and technology.

Du Qiu understood what Ning Shuangshuang meant, nodded and said: "Don't worry, I cherish my life, once I complete the blocking deployment, I will withdraw all the people who can evacuate, and the artificial intelligence will command to complete the blocking mission." ”

"Okay, then I'll start executing the evacuation plan now."

After Ning Shuangshuang finished speaking, he stared at Du Qiu and added, "Du Qiu, don't lie to me!" ”

Du Qiu smiled, hugged Ning Shuangshuang, and said, "Of course I won't lie to you, I still want to marry you!" ”

Ning Shuangshuang's head rested on Du Qiu's shoulder, and he didn't see a trace of pain flashing in Du Qiu's eyes.

"I'll always be waiting for you!"

Next, Ning Shuangshuang left to make final preparations for evacuation, while Du Qiu brought Hao Jian and others to tell the design of a new type of main warship as quickly as possible.

Time was pressing, and he could no longer let the battleship design team explore it on their own, Du Qiu needed to complete the design drawings as quickly as possible, and the artificial intelligence Stardust began to arrange production at full speed.

As for the most powerful weapons, as well as the development and production of new fusion energy power, they will be carried out simultaneously, not waiting for each other.

Some of the testing and verification links have been omitted, and at this time when the possible civilization is in danger, as long as the battleship can be produced, it will go directly to the battlefield.

After Du Qiu finished telling Hao Jian about them, he immediately selected a group of people and prepared to go to the Mars base.

And Hao Jian and they don't have to stay, because with the speed of 3,000 kilometers per second in the celestial realm, it takes about 16 days to fly out of the solar system.

With the current miraculous technology quantum communication technology, there are relay satellites in the solar system, which can ensure communication, and once it flies out of the solar system for more than 10 astronomical units, real-time communication cannot be guaranteed.

In fact, at the speed of the celestial realm, it will take almost 100 years to really leave the Oort cloud range of the solar system.

This is the sadness of low-level civilizations, for civilizations of level 3 and below, there is no ability to fly faster than the speed of light, and if they want to fly between star systems, they are all measured in hundreds of years.

Therefore, Du Qiu basically judged that the alien civilization fleet outside the solar system would most likely not be lower than the third-level peak level.

This is also because the White Spot is located at the midpoint between the solar system and the Barnard system, and it is very likely that this alien civilization fleet sailed from the Barnard system and rested there to recuperate.

If it weren't for that, Du Qiu would definitely believe that the other party was a fourth-level civilization or above, could fly faster than light, and was a real alien civilization from afar.

But even if it is a third-level peak civilization, it is not the current strength of magical technology that can be defeated, it is really too inadequately prepared, and even a decent space fleet has not yet been formed.

If Du Qiu is given a year, even half a year, relying on a strong robot production capacity, Du Qiu can form a space fleet of sufficient scale, play ship-sea tactics with the other party, and drag the enemy to defeat.

Now, it's only three months, and I can barely fight.

Du Qiu knew that this was a battle of life and death, and he had to stay to ensure that the construction and marshalling of about 100 capital ships would be completed within three months.

What's more, no one has more experience in interstellar wars than him in magical technology at this moment.

Du Qiu learned countless battle materials from the database of shipbuilders, and although the battles between higher civilization levels at that time were also very valuable for reference.

The spaceport of the Celestial Realm was busy, and the planetary buses were constantly flying up and down from the Blue Star, bringing many people evacuated from the Blue Star.

Du Qiu took the group of people left behind and prepared to leave on the transport ship, Ning Shuangshuang was busy arranging the evacuation of the Heavenly Realm, and did not come to see Du Qiu off, of course, he was afraid to come.

"Boss, I want to stay with you!" Da Liu got the news and hurriedly came.

"Don't make a mess, hurry up and cooperate with your sister-in-law, prepare for the evacuation of the Heavenly Realm, and set off as soon as possible, only after you enter the safe escape zone, I can evacuate with peace of mind to meet you."

"Ah, Boss, you ......"
