Noah has been very busy during this time, in addition to the repair of planetary engines, the expansion of the fleet and the research and development of new strategic weapons have also become the top priorities. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

The only asteroid belt of the Centaur Three Star was heavily mined by Noah, which became the last resource supply line for civilization.

Fortunately, Noah had a large amount of resources when he left the solar system, so even if the asteroid belt was extremely barren, it could barely meet Noah's current resource consumption.

The first interstellar probe has been made, and Noah named it the White Dove.

In ancient times, humans used to communicate with carrier pigeons, and the white dove could symbolically represent peace and freedom.

The interstellar probe will not be launched on a rocket, but it will be equipped with the latest impulse engine, not so much a probe as a near-light drone, after countless adjustments and improvements by Noah, it will be able to travel interstellar at speeds above 0.5 times the speed of light.

The shape of the white pigeon resembles a feather, 3 meters long and 0.6 meters wide, but the overall thickness is only 1 mm, the shell is a white gold smooth shell covered with a nuclear film as a whole, due to the dense nuclear arrangement on the surface, the surface of the white pigeon has almost no coefficient of friction, the ultimate smoothness, better than the reflectivity of the mirror, coupled with the feather-like fluid plane design, the white pigeon can even fly near the speed of light in the atmosphere.

From the outside, it is more like a work of art than a probe, like the feathers of an angel spreading its wings in a painting, the most cutting-edge material technology, the latest impulse engine, and the most compact new generation of quantum computers......

Judging from the scientific and technological content alone, the technology possessed by this white dove is even better than that of the flagship spaceship of Noah's fleet, the gamma-class spaceship.

The only disadvantage of the white dove is that it is too small to carry weapons and plasma shields, but Noah is not worried, with the materials and design of the white dove, as long as he does not plunge headlong into the star, it is not a big problem to hit the planet head-on.

The white dove flew out of the Ark (ark) and flew smoothly and quickly towards the sea of stars in the distance, and in the blink of an eye, it had disappeared from sight.

The white dove is like Noah's eyes, constantly extending to the other side of the galaxy, if the picture transmitted back by the white dove is shown to someone, it will definitely be thought that the white pigeon's camera function is malfunctioning, because under the condition of near the speed of light, the red and blue shift caused by the Doppler effect has made the light wave frequency beyond the limit range that the human retina can perceive, and all that can be seen is darkness.

But Noah could see it, and Noah knew that the white dove was currently sailing at 0.7 times the speed of light.

The impulse engine can theoretically increase the speed of the accelerating object infinitely to close to the speed of light, but Noah has not done an impulse engine acceleration test beyond this speed, although the construction of the white dove itself is an excellent acceleration test material, but Noah does not want to take this risk for the time being.

The impulse engine accelerates the accumulation of test data, and it is enough to use a low-cost shuttle, and there is no need to use something so expensive as a guinea pig.

The White Dove sailed very fast, and in the blink of an eye, it had already left the confines of the Centaur galaxy and flew straight towards the Gliese 581 galaxy, but even at 0.7 times the speed of light, it would take nearly 35 years to reach the Gliese 581 galaxy 24 light-years away......

But it doesn't matter, this period of time is just the right time for Noah to carry out the repair of planetary engines and the research and development of new strategic weapons.

In terms of kinetic energy weapons, Gauss weapons have been regarded as the ultimate in existing technology, and the fine needle-like high-temperature metal vapor at sub-light speed has reached the extreme of electromagnetic weapons in terms of penetration and destructive power.

Noah's next main attack on new weapons is mainly divided into three aspects.

Nuclear weapons, energy weapons, gravitational weapons.

At present, it seems that the most technological breakthrough can occur in a short period of time is undoubtedly nuclear weapons.

The principle of nuclear weapons is just the application of nuclear fusion or fission, compared with the nuclear fusion engine that can stably output energy, the nuclear weapon that radiates energy at one time is less technical, human civilization used the principle of nuclear fission to create an atomic bomb, and the principle of primary nuclear fusion made a hydrogen bomb, and Noah, who mastered the fusion of heavy elements, will go further in this.

Helium flash is Noah's favorite fusion reaction during the evolution of stars.

Helium-based fusion is the easiest fusion to achieve and easiest to control in addition to hydrogen isotope fusion, and helium flash itself has the power to be close to a supernova explosion, and it can even be directly said that helium flash itself is a supernova explosion of medium stars whose mass does not meet the requirements of supernova explosion.

Nuclear weapons themselves can be designed in yield, just like a hydrogen bomb, as long as there is technology, you can infinitely design the upper limit of the yield of the hydrogen bomb, such a weapon has no power limit, you can even make a super hydrogen bomb that can destroy the galaxy, as long as it can be designed.

In the case of helium flash weapons, it is just a further reaction on the fusion reaction of isotopes based on hydrogen in the hydrogen bomb, and when the hydrogen element is fused into helium, the superweapon that simulates the helium flash of the star is completed on the basis of helium fusion.

In other words, such a weapon, the hydrogen bomb can only be regarded as its fuse, and when it releases the power that the hydrogen bomb can have, it will carry out its real rage, because it is a complete fusion reaction, so it will not produce any radiation.

Until the search for a way to obtain energy other than mass energy transformation, nuclear weapons will always be the most explosive weapon.

For Noah, who can already achieve controlled fusion on helium and has also observed a small helium flash explosion at close range inside the spacecraft, there is no difficulty that helium flash weapons need to overcome in theory.

As long as a reasonable weapon model is designed, the manufacture of helium flash weapons will become a matter of course.

For a long time, Noah focused her attention on the development of civilization, but what she didn't know was that in the distant Sidenia civilization, Sidenia had already ushered in its first turning point before Noah received their radio waves.

Four years after the launch of space waves, Sidney, the National Central Academy of Sciences, the satellite signal and reception base, Ethel was in a state of excitement that made him dizzy, it was already late at night in Sidney, except for the guards on duty outside the Academy of Sciences, this base was already empty.

Ethel was just here to take away the documents he had forgotten here during the day, and after he took the documents from his studio, he planned to return the way he came, but when he passed through the radio wave receiving room, the faint sound coming from the room made Ethel feel a little strange, and the sound of signal reception coming from it seemed to have a mysterious allure.

"Didi......"

Ethel lay on the door of the radio wave receiving room, listening carefully to the sound inside, the radio wave receiving sound is not a rigid simple tick, but a prompt sound that conforms to a certain code frequency rule, a professional like him, can even listen to such a receiving prompt sound, to determine whether the received signal is specially modulated.

The papers were scattered to the ground, and Ethel's body on the door began to tremble, as if he was crazy to open the door, but he found that he did not have the key, and he kicked the door hard, making the steel door make a heavy sound, and he himself was shocked by the force of the recoil and sat on the ground.

Ethel sat on the ground and looked at the door that was still closed, the sound of ticking from inside still ringing in his ears, and he rushed out with a crawl, knowing that the guard on duty must have the key here.

He quickly rushed to the guard's duty room, the guard on duty here of course knew him, the vice president of the academy, and after knowing that he wanted to get the key to the radio wave receiving room, he took out the key from the drawer and got up to help him open the door, who knew that the vice president snatched the key from his hand and rushed towards the research institute, which made the guard feel very strange, and had to run towards the research institute with Ethel.

Ethel came to the door of the radio wave receiving room, his hands trembling with excitement couldn't get the key into the keyhole, and the guards behind him, who were panting and following him, were a little puzzled why the vice dean's strength was suddenly so good.

Ethel finally inserted the key into the keyhole, opened the door of the receiving room, and came to the main terminal, where six red stars flashed silently on the black identification screen.

The red six-star is an extreme of the information that this base can receive, and the possibility of the five-star information containing intelligent information is more than 95%, and the six-star represents that this information is exactly the same band as the band used by the base to receive and transmit signals, and the writing rules used are exactly the same as those of the base, and even the translation is not required, and it can be displayed directly on the recognizer.

In the dizzying excitement of Ethel, he pressed the read button on the recognizer with trembling fingers, and a line of words appeared on the screen.

[Dear neighbors, we live in the solar system 20.4 light-years away from you, and you can call us the Kara civilization. Our interstellar voyagers have received a message from your world and as a friendly neighbor, I would like to give you a piece of advice-]

【Protection-Hold-Peace-Quiet】

[Within a hundred light-years, in addition to us, there is also a higher civilization that can carry out interstellar travel, they cannot survive in the original galaxy for some reason, so they took their home star to embark on a journey to the galaxy, a stable and stable galaxy is what they urgently need at the moment, and the galaxy where your civilization is located may be the best choice in the next hundred light-year. 】

[So, please be quiet.] That civilization has the ability to accelerate development that none of our civilizations can match, even in a harsh environment, they have developed a fairly high level of civilization, even we are now trying to avoid conflicts with that civilization, although it may be offensive, your current level of civilization will be vulnerable in front of that civilization. 】

[So, please be quiet.] You are fortunate that our interstellar probe has just arrived near your galaxy, so we must have received your message before that civilization. Unfortunately for you, you are also using indiscriminate radio communications, so that civilization will certainly be able to receive signals from your civilization, but if you are lucky, they may not be able to determine the exact location of your civilization. 】

[So, please be quiet.] Since this message, do not answer any other information from the universe, let alone take the initiative to communicate with the outside world, our civilization is temporarily unable to leave the solar system due to some internal problems, and we do not want to be the enemy of that civilization again, so we are sorry, we may not be able to help you...... Good luck to you, dear neighbors. 】

[Your friendly neighbor - Sincerely, Kara Civilization. 】
