It's reasonable for me to have a two-way foil for a second-level civilization, right?

This is simply a fatal problem for today's human fleet.

In addition to the above technologies, artificial gravity technology has also been successfully realized in the laboratory.

After hearing the news, Lu Yongchang hesitated for a while, and reluctantly gave up the idea of ​​applying it to all starships.

the reason is simple.

The transformation scale is too large and consumes too much material.

In a sense, the cost of rebuilding a starship in all aspects even exceeds the cost of rebuilding a starship.

Therefore, in the entire fleet, only some areas on the flagship [Earth] have been equipped with artificial gravity facilities.

……

"The time has come."

"Resources are seriously insufficient, and many scientific research work in the laboratory has been suspended."

Lu Yongchang stood in the [Earth] command center, feeling the comfort brought by artificial gravity, and said in a deep voice: "The fleet transformation is basically completed."

"Humanity needs to find new star systems!"

After speaking, he turned his head and glanced around, seeing that there was no objection, he asked He Bilin who was sitting in the first row of seats.

"Academician He, has the screening of habitable star systems been completed?"

He Bilin nodded, and subconsciously reached out to touch the electromagnetic adsorption device on the side of the seat, but found nothing.

He stood up in embarrassment, walked quickly to Lu Yongchang, and said loudly: "At present, we already have mature planetary transformation technology, so I have relaxed the screening conditions for habitable planets."

As he spoke, he swiped a few times on the holographic projection beside him.

A string of lists and a star map were presented in front of everyone.

"Considering that the fleet's antimatter reserves are seriously insufficient, the fleet's first voyage target is the HIP13.7 star system located 3376 light-years away."

"According to our observations, the HIP3376 star system is a binary star system built by two red dwarfs."

"Currently, no evidence of planetary existence has been observed."

"After the successful deployment of the [Dyson Cloud] device, the fleet will collect sufficient energy for navigation within 50 years."

The proposal to find a star system without planets to supplement energy actually came from Lu Yongchang.

Although human civilization has been successfully promoted to a fifth-level civilization, and has even mastered a small part of the technology of a fifth-level civilization, the combat power of human civilization, in a sense, is not even as good as that of the fourth-level civilization.

energy!

The energy consumption of interstellar wars is a terrifying value!

Whether it is a curvature engine or a gravitational shield, all equipment that involves a gravitational field generator is a big energy consumer.

Therefore, it is impossible for the remaining energy reserves of the human fleet to support a vigorous interstellar war!

In star systems without planets, the probability of civilization is also greatly reduced.

After all, in the young universe, energetic stars can be seen everywhere, and the scarce ones are actually habitable and long-term developing planets.

In addition, although the human fleet has undergone small-scale transformation, these starships equipped with curvature engines are still satellite-class starships.

In order to have a fifth-level civilization planetary starship, human civilization still needs a period of development and hard work.

"What's next?" Lu Yongchang raised his eyebrows, as if realizing something, "I remember that some time ago, a lot of Dyson clouds were newly built at the starship factory. If we unfold them all..."

"I am afraid that a lot of antimatter can be produced in 50 years."

"Where is the final destination of the voyage?"

"Kepler 452, professor." He Bilin said calmly, "The distance to the star system HIP3376 is 1539.2 light-years."

After the voice fell, there was a commotion in the command center.

1539.2 light years.

This is an extremely exaggerated distance.

At least, for previous human civilizations, this was a long and desperate journey.

He Bilin added softly: "It only takes 154 years to sail at ten times the speed of light."

"Considering that materials need to be replenished two to three times midway, it is conservatively estimated that the entire voyage will be about 300 years."

300 years!

Only need 300 years!

Looking at the numbers in front of him, Lu Yongchang's pupils trembled slightly. For the first time, he deeply experienced the transformation of human civilization.

"Kepler 452b?" After a moment of silence, Lu Yongchang asked rhetorically.

"Are you sure it exists?"

In the age of the earth, Kepler 452b was a planet full of magical meaning.

This is the first potential super-earth rocky planet discovered in human history. At the same time, various calculation results show that this planet, like the earth, is in the habitable zone of the star system!

This has brought endless imagination to human beings thousands of years ago.

However, in the era of the earth, due to the limitations of observation technology, humans have not been able to prove its existence, and only count it as an exoplanet candidate.

After the occurrence of solar helium flashes, although the observation technology of human civilization is constantly increasing, the long distance of more than 1000 light-years has directly crushed the desire of the Academy of Sciences to carry out observations. If you have this spare time, it is better to consider how to avoid The crisis is reliable!

Chapter 660 Target: Kepler 452

"It has been confirmed."

He Bilin said firmly: "According to the latest observation results, the Kepler 452 star system has a total of six planets."

"The general structure is similar to that of the solar system."

"At the same time, Kepler 452b is confirmed as a rocky planet, its mass is about five times that of the Earth, and its surface is about 2g."

"A revolution period is approximately 385 Earth days."

"It is also located in the habitable zone of the star system."

"As conjectured thousands of years ago, it is almost equivalent to a second Earth."

Lu Yongchang's heart beat violently a few times, and a sense of anticipation that he hadn't felt for a long time suddenly rose.

"but……"

He Bilin shrugged and said regretfully: "We found that there is a lot of carbon dioxide in its atmosphere, which will cause a considerable greenhouse effect."

"Zero's simulation results show that there are relatively few water resources above Kepler 452b, and the highest surface temperature may be above 120 degrees Celsius."

"The temperature difference between day and night is large, and the lowest temperature is about -50 degrees Celsius."

"In general, it is different from the imagination of thousands of years ago. It is very likely to be a barren planet."

Lu Yongchang laughed dumbfounded: "This is not a big problem."

"Planet terraforming technology can quickly turn it into Earth 2.0."

"However, I need to hear your reason." Lu Yongchang said with a serious face, "Why did you choose it?"

"I just glanced at your list."

"Within one hundred light years, there are ten planets on your shortlist."

"Why, did you choose such a distant planet?"

"You should be aware that long journeys often mean variables."

Seeing Lu Yongchang's serious expression, He Bilin pondered for a moment, organized his words and then explained.

"One of the most critical reasons is that it is closer to Sagittarius A*, the central black hole of the Milky Way."

"This means more abundant supplies."

"There are also many benefits to the future development of human civilization."

"But dense star systems will also give birth to more civilizations." Lu Yongchang sighed in a low voice, "This will bring more conflicts."

"In other words, more opportunities for cooperation." He Bilin interrupted Lu Yongchang's words, and corrected with a smile, "Although the fifth-level civilization is not considered a top existence in the Milky Way, it will not be easily rubbed by people. pinch."

"Absorb affiliated civilizations and build a civilization map. Only in this way can human civilization survive better."

In the command center, fell into silence.

Lu Yongchang frowned slightly, carefully thinking about the pros and cons.

The benefits of affiliated civilizations are many.

Some time ago, [Nus Civilization] was absorbed as an affiliated civilization, allowing him, and everyone in the Academy of Sciences and the Parliament to taste the sweetness.

Although [Nus Civilization] currently has less than 0.1% of its scale left, the potential of its race is immeasurable!

The collision between different civilizations will make the technological level of this civilization rise rapidly!

But the disadvantages are also obvious.

War, with a high probability, will always accompany human civilization.

In fact, according to Lu Yongchang's idea, human civilization should shrink in a corner, and with the help of the technology tree, develop silently to level eight... No, level nine, and then stand up and make your own voice!

At that time, he is [-]% sure to solve all crises easily!

What a sweeper, what a pastoral...

It's just an affiliated civilization within the jurisdiction of the People's Federation!

But judging from the current situation, this is obviously impractical.

The abundance of materials at the edge of the Milky Way cannot support the normal development of a higher civilization.

Thinking of this, he sighed again, letting go of the idea of ​​continuing to develop in his heart.

"Ready to sail!"

"Zero, start planning the route and unify the fleet!"

after the order is given.

Scattered in space, the various starship factories and various facilities began to gather gradually.

Outside the porthole, starships and drones, large or small, galloped by.

Under Zero's planning and control, there is an indescribable sense of order in the chaotic waterway.

Under Lu Yongchang's watchful eye, the originally disorganized fleet is rapidly becoming organized as time goes by.

"According to the plan, the fleet will conduct routine sailing for half a year driven by the antimatter engine."

He Bilin's voice came from behind, pulling Lu Yongchang's attention back from the porthole: "The original plan is that the waking personnel in the fleet will enter hibernation one after another within the next six months."

"Professor, you..."

"I don't hibernate." Lu Yongchang said cheerfully, "I haven't experienced the feeling of curvature sailing yet, why sleep in winter?!"

"It's not too late to hibernate after the fleet enters a state of curvature."

After finishing speaking, he glanced at He Bilin in surprise: "Those academicians, can they part with such a historic scene?"

He Bilin smiled wryly when he heard the words, and stretched out his hand to call up the holographic list: "Professor, what they said is exactly the same as yours."

"Except for the original test pilots, everyone is unwilling to enter hibernation, and has to wait until the moment when the curvature flight begins."

"Hahaha!" Lv Yongchang clapped his hands and burst out laughing, "As expected."

"okay!"

He patted He Bilin's shoulder lightly, and said reassuringly, "It's just an extra half a year of supplies. There are only a few people in the Academy of Sciences, so it won't have much impact on the plan."

Suddenly, Lu Yongchang seemed to realize something, turned his head and glanced at the list again, and said lightly, "Xiao He, where is your name?"

"You decided to go into hibernation now?!"

Lu Yongchang looked at He Bilin in front of him in disbelief.

What a joke!

This is curvature sailing!

He didn't believe anyone could resist the temptation to experience curvature sailing for themselves!

"Cough..." He Bilin scratched his head with a smile full of embarrassment, and coughed lightly.
