Before setting off again, it took about two years for Yun Xinghe and them to transform the Feitian from beginning to end.

Mainly by using the "weight reduction" characteristics of the floating stone element, a large number of miniature "floating balls" are installed inside the Feitian, a floating ball can eliminate the mass of 10 cubic meters of space, and 10,000 are evenly installed inside the Feitian to achieve a weight reduction of 85%.

Only the power compartment and the crew living compartment are not covered by the "weight elimination field" because they cannot be without mass.

However, when the speed of the Flying Sky reaches its maximum speed and the entire crew enters a long dormant state, the distribution of the "floating ball" inside the spacecraft will change, and the area occupied by the weight reduction field will become larger, and the spacecraft will achieve a 97% weight reduction.

In addition, in the case of ultra-high flight speed, the force gold on the surface of the spacecraft was originally difficult to resist the impact of large-density materials, but the "weight reduction field" of the floating ball overlapped with the electromagnetic field of the force gold, and even if the Feitian was sailing at a speed close to the speed of light, it was not afraid of being damaged by some low-density materials at all.

Because the collision of something without mass will be like a photon bouncing off a glass mirror, there is no momentum balance, and the high-speed particles will only be directly bounced by the high-intensity field at the moment when they are about to approach the surface of the Feitian.

Therefore, when the Feitian is sailing at a faster speed, as long as it does not encounter a large meteorite, there is no need to worry about particle collision.

Even if you break into the inside of the storm's huge nebula, you are not afraid of being blown around.

Even if you are close to some massive black holes, you will not worry about being sucked in and unable to get out.

Gravity is the source of all interstellar disasters, and without gravity, everything is good.

After the transformation of the Feitian was completed and a large number of supplies were replenished, on the 22nd, it set sail again!

This time, the target is 55 light-years away, in a dark corner with no light, an unknown galaxy with a star obscured.

Yun Xinghe calls it a "hidden civilization".

The other crew members felt very strange, how could the captain be so sure that there must be a hidden civilization in that dark and mysterious corner?

What if it was a black hole, or an extinct star?

You must know that to cover up all the light and heat radiated by an entire star, this is a technology that even the Blue Star Federation has not fully mastered, or rather, it is not impossible, but such a huge amount of energy, the Federation does not know how to use it.

"The Milky Way is a spinning body, on six huge cantilever arms, the distribution of stars is quite uniform, generally every four or five light years, there must be a star system, and the stars in this place disappear too abruptly, like a pit suddenly appears on the flat ground." ”

"In addition, according to the gravitational fluctuation data and the offset of the starlight, there must be something here, if it is not a black hole, it must be a hidden civilization!"

Berekov also nodded: "I have calculated, this place, there should indeed be a star, eh, or black hole." ”

"It's okay if it's a black hole, the scientists of the Federation, there is not a lot of research on black holes, we can go over and help do some scientific experiments. ”

"But if it's a hidden civilization......"

"A civilization that can obscure the stars so that it does not show a glimmer of light, the level of technology is not higher than that of the Federation, but it will never be much worse, and if we get close to them, they will treat us as enemies......"

Lan Xiulong said with some worry on his face: "We have to be ready to run away at any time." ”

"We're just interstellar explorers, not federal diplomats, and if there really is a high-level civilization there, a flying ship, and a few of us, I'm afraid we won't be able to deal with it. ”

Sugaru said, making a suggestion: "It's better to change your target and go to those galaxies where no one is around." ”

"No!"

Yun Xinghe shook his head: "To a certain extent, we are both interstellar pioneers and civilization diplomats, if we don't try to deal with various civilizations and try to eliminate their doubts, our subsequent exploration activities will definitely be disrupted, and even leave huge hidden dangers...... We must ensure that the place we walk is a safe place, and if it is not safe, we have to make the road smooth and safe, which is another part of our mission in addition to finding a habitable planet. ”

"As interstellar pioneers, sooner or later we will encounter alien civilizations, and it is impossible to bury our heads and ignore them, we must learn to deal with them. ”

The crowd nodded.

Yun Xinghe smiled slightly, this great truth was actually what he learned from the course "Cosmic Diplomacy" in the Academy of Astronautics, and he just read it from the book.

In fact, without knowing the other party's moral standards and good and evil, dealing with a higher civilization is an unknown thing, and the cosmic dark scientist has put forward a point of view: when dealing with a strange civilization, the first thing to do is to hide yourself, less exposure of your own information, if you expose more, the closer you are to danger.

"This is actually a kind of persecution paranoia, a bit like the so-called chain of suspicion, that is, everything around you is seen as malicious, unfriendly, and uncommunicative, in fact, if all civilizations had followed these dark laws, the planet that was first promoted to a higher civilization would have ruled the entire galaxy long ago. ”

If the interior of civilization also follows these dark logics, more than 90% of civilizations will destroy themselves before destroying other civilizations, because these logics are also applicable to their peers, just like many world wars in history, resources are limited, and if you want to master them all, you must first eliminate those malicious kinds. ”

"If a civilization wants to go to the interstellar, it must first put aside conflicts and differences, resolve disputes through negotiation, give up devastating wars, and use resources rationally......"

"In the same way, why can't they trust other civilizations as much as they trust their fellows, and try to get along with them?"

"The universe is very big, if you can't put your own vision on the same scale, these people will die sooner or later from their own narrowness. ”

The words of the teacher of "Cosmic Diplomacy" have made Yun Xinghe remember it deeply.

In addition, the hidden civilization 55 light years away, the old man in his brain also introduced him, this civilization, science and technology have indeed developed to a very amazing extent.

The exploration spacecraft in another parallel space, after intruding into this galaxy by mistake, the spacecraft was quickly destroyed by a number of advanced devices sent by the civilization, and the explorers on the ship were all captured, and during the internment of the civilization, among these explorers, the wise captain, in the process of negotiating with the high-level of this civilization, used his theory to completely defeat the other party's "dark forest" theory, so that the other party was enlightened, and released them, not to mention, this civilization, but also with the Blue Star Federation, established formal diplomatic relations.

And this has also become a very classic case in the history of interstellar diplomacy of the Blue Star Federation, although the wise captain did not find a few habitable galaxies for mankind, but also became one of the top ten outstanding pioneers in the 2500-year interstellar exploration history of the Federation, which will forever be recorded in history.

With the current defense of the Flying Sky and the ability to escape at high speed, it is not afraid of the opponent's advanced devices.

This is the reason why Yun Xinghe insists on going to this hidden galaxy.

……

You're all set!

"Increase the power of the material reactor!"

"Main engine starts!"

"Start accelerating!"

The blue flame of the tail engine of the Feitian was extremely dazzling, and in fact, only one of the three main engines was started at full power.

Even if there is only one, under the huge thrust, the Feitian, which is as light as a feather, continues to accelerate with an acceleration close to 10G, and rarely interrupts, for hundreds of hours.

0.1C、0.2C、0.3C……

Ignoring the impact of matter, within the influence range of the star system, the speed of Feitian accelerated to 0.85C.

The main engine was then turned off and the interstellar roaming phase began.

Bridge control hall.

"Now the speed of the spacecraft is 0.85C, the time dilation is 1.898 times, and it will take us about 64 years to reach our destination, in fact, we only need to stay on the ship for 34 years to reach that occult galaxy. Lan Xiulong said.

"It's only been thirty years, we shouldn't have to go into the dormant chamber, right? Sugaru said, the last time he had been lying in a dormant warehouse for 160 years, the feeling of just getting out of the dormant state made him feel that it was better not to sleep.

"What can we do without hibernation, play cards, watch movies, or play games?" said Yun Qiaoqiao, holding her cheeks.

"I like to play games, shooting games. Gu Fan hugged his hand and said.

"It's a pity that the starry sky outside the spaceship can't be observed, otherwise you can observe some magical astronomical phenomena. "I like astronomy very much.

Feitian is in a sub-light speed flight state, at this speed, even if the spacecraft can receive some starlight, but because the speed is too fast, these starlights are strangely elongated, like running on a highway composed of light, if the speed of the spacecraft is faster, it is estimated that no stars around it can be seen, only countless rays of light can be seen flying or backwards, this spaceship, as if in a channel of light, is moving rapidly.

"Let's go to the dormancy warehouse and sleep for 30 years, 30 years is long enough, don't spend it in boring fun. ”

Yunxing River, dormancy is not good for the body, but if you don't sleep, you will be super bored, and there is no benefit.

"Oh~"

The crowd replied weakly, and reluctantly, walked towards the sleeping room.
