The most valuable thing about this ship was undoubtedly the various instruments that had been disassembled and assembled repeatedly, and the Zerg scientists who were forced to go into business and were constantly explaining the functions of the parts.

But now, the star map is out!

Especially when there are similar coordinates of the Milky Way on the star map, everything changes.

Having traveled so far and crossed so many stars, isn't it just when I was forced to jump away on Mars, and then I wanted to return to the familiar blue star.

Searching, going around.

It wasn't until Lu Yu looked at the holographic projection of the galaxy in front of him that he couldn't believe that the hope of returning to the blue star had appeared in front of him so inadvertently.

The Milky Way is a kind of spiral galaxy where the solar system is located, a kind of spiral galaxy, which is elliptical and has a huge disk structure, and the latest research shows that the Milky Way has four clear and fairly symmetrical spiral arms, which are 4,500 light-years apart, and the number of stars is between 100 billion and 400 billion.

Don't look at the number of stars, if the Silver Star can return to the Milky Way, it will be easy to lock the solar system.

Viewed from the blue star, the center of the Milky Way is the brightest area of the Milky Way, with its direction in the constellation Sagittarius. From Sagittarius, a hazy white band of light seems to pass to the constellation Auriga on the back. The band of light then continues the rest of its path back to the vicinity of Sagittarius, dividing the celestial sphere into two roughly equal hemispheres.

In such a way of comparing the two, Lu Yu could easily find the position of the blue star as long as he jumped a few more times in the galaxy, and it was no wonder that Lu Yu immediately became excited.

"Compared with the observed Milky Way star map at Base Zero, the similarity rate is more than 80 percent."

"But because it is 20 million light-years away from the Zerg observation point, the specific situation of the galaxy has evolved into a completely different shape, but after calculation, the probability that the galaxy is the Milky Way is more than 50%."

After Seven's brief debriefing, on the holographic projection was a freshly transcribed star map.

A barred spiral galaxy with diameters ranging from 100,000 to 180,000 light years. There are about 100 billion to 400 billion stars and possibly 100 billion planets.

It is dense with gas and dust, oblate in the form of a spheroid, with a large disk structure, consisting of a bright and dense core, two main spiral arms, and two unformed spiral arms, which are about 4,500 light-years apart.

"It's like the structure of the Milky Way!"

"Are you stupid? The basic structure of the bar galaxy is basically the same as this! ”

"But this is already the galaxy most similar to the Milky Way since Lu Yu set foot in the universe."

A large number of astronomers have discussed that if Lu Yu can return to the solar system before the arrival of the unknown fleet, then the safety of Blue Star can basically be guaranteed.

And at the same time, Lu Yu also left a large number of assets in the big universe.

The giant spaceship in front of you is not mentioned for the time being, as long as the space bubble obtained from the folded space can be given to human civilization, it can allow the entire civilization to step directly into the interstellar age without relying on the Silver Star.

Moreover, it is also a lizard civilization, as well as the relics of the Alliance of Conscious Lifeforms, all of which contain great value.

Once Lu Yu returns, these things will no longer be beyond the reach of human beings.

Scientists can go to the field and then transport them back into the solar system to become human things.

The current Silver Star is no longer the space jumping machine that only teleports randomly, this thing is incalculable for a civilization!

And Lu Yu has been drifting for so long, if he can return to the Blue Star to rest and rest, then he may also be able to complete the vision in his heart and start the next stage of evolution.

Leaving in a human body, returning in a human body, and then there is glorious evolution.

This is a thought that has been hidden in my heart for a long time, and even Seven does not know.

Since this is a rare opportunity, how can we continue to wait?

The Silver Star's energy system was damaged, and it only stored energy five times during its nearly one-year stay.

But it is completely enough for the detection of the true and false Milky Way this time, and these zergs have to find a way to arrange it.

It's also an energy issue, and the Silver Star's interspace communication system is no longer available. Initial Update @ (This chapter is not finished!) )

Chapter 30: The Colorful Nebula

It can be turned on for a long time, otherwise it will affect the charge of the space jump.

Therefore, how to squeeze the surplus value of this zerg has become a problem.

It's just that it's not a big problem, and the solution is sent by the Zerg!

The advanced artificial intelligence suppressed by Seven quickly turned into her shape. @精华\/Shuge Error-free Debut~~

The giant ship will still be under the management of this artificial intelligence, and the Zerg inside will transcribe their technology tree into the universal language of the universe over and over again, and then receive it by Seven through regular interspace communication, and then send it to Base Zero.

The arrangement is clear and clear.

And if there is any abnormal movement, it will only be a waste of space jump for the Silver Star, and some Zerg will have to pay for their lives.

The result was a spectacle in which a steel spaceship the size of Saturn had turned into a super-Earth moon, while it was also swallowing out a large amount of mechanical debris and erasing the traces of the battles that had taken place here.

When the Zerg Second and Third Fleets arrive, they will understand what a special surprise is.

From an intruder to a guardian, it can be regarded as a bad taste left by Lu Yu.

At the same time, Lu Yu did not forget to leave an order to conquer other continents for his holster Nemo, and how to implement it has left a space bubble in his core to carry plans and computing power.

Once verified, maybe back soon.

Thinking of this, Lu Yu did not hesitate, and jumped directly away from the folding space where he had stayed for a long time.

………..

Directional space jumps are full of unknowns.

Because the position of galaxies in the universe is not motionless, the galaxy that appears to be the Milky Way has been in the universe for 20 million years when it was observed at the Zerg observation point.

The galaxy is very different from what it looks like.

Even if Seven's computing power reached a level that would surprise even the ninth-level civilization, the result of this directional space jump was still unknown.

They may have jumped into the void of the universe in one go, or they may have jumped into a black hole.

When the starry sky beyond the Silver Star came into view, Lu Yu understood that they had arrived at their destination smoothly this time.

This is a large nebula with a length and width of more than ten light years, and this nebula belongs to the luminous nebula. There are three types of nebulae, which are luminous nebulae, reflective nebulae, and dark nebulae. Luminous nebulae, as the name suggests, emit visible light on their own. A reflection nebula is a reflection of light from other stars, while a dark nebula is the absence of stars nearby and no stars inside, so in the visible band, it is invisible, but it can be found by looking for a black field in a bright background.

The Luminous Nebula is one of the most magnificent sights in the universe, dotted with every color you can imagine.

At the same time, they are an extremely efficient and huge starfactory. Countless interstellar dust gathers into stars, and the ultraviolet rays emitted by young stars ionize the interstellar dust, so in the visible light band, they appear reddish slightly.

So the starry sky here is not dark, but colorful. Here, you can see a magical phenomenon, bright young stars set in the magnificent color of the sky, like bright gems, very beautiful.

But in the midst of beauty, there is danger. Because of the large concentration of young stars, the radiation levels here are dozens of times higher than in the rest of the universe. Moreover, the larger the star, the shorter its age, and the shortest-lived giant star has a lifespan of less than 10 million years.

When a star dies, it has a different fate depending on its mass, and a star similar to the mass of the Sun will turn into a white dwarf after death. After a supernova explodes, the remaining core mass becomes a black hole or neutron star.

The material they throw out will spread in the form of nebulae over tens of billions of light-years, and over time, this material will become new stars.

Therefore, behind this unusually beautiful colorful canopy, there are not only dotted stars, but also more than one neutron star, white dwarf star and other stars may be hidden, and even, the most dangerous star in the universe - black hole.

But these are nothing to Lu Yu, he used to come and go freely in the central black hole, and the armor of the Silver Star is not in such a cosmic environment. (This chapter is not finished!) )

Chapter 30: The Colorful Nebula

There are celestial bodies that can threaten it!

"This nebula is so beautiful!"

"Is there such a nebula in the Milky Way? This can also be regarded as one of the eye-catching marks, right? ”

While Lu Yu sighed, he hurriedly looked at No. 7.

Because of the obscuration of the nebula, the stars beyond the nebula appear unusually faint and even imperceptible. To this end, the 7th uses a variety of observation methods, such as visible light band, X-ray band, infrared, ultraviolet band and other observation methods.

However, compared with the neutrino detectors, gravitational wave detectors and other instruments carried in the previous Rubik's Cube, the power of these detection instruments created by Lu Yu's mastery of technology has really decreased a lot.

But if you can use it now, it's a big deal to go back and dismantle the equipment of the giant spaceship in the future!

Taking the nebula in front of you as a reference, judging from the captured data, the scale of this nameless colorful nebula will definitely not be less than 300 light-years.

There are also many nebulae that have been observed by humans in the Milky Way, such as the Orion Nebula, the Fox Dumbbell Nebula, the Trilobe Nebula, the Lagoon Nebula, the Flying Eagle Nebula, the Cat's Eye Nebula, etc., which are all nebulae familiar to astronomy enthusiasts.

If the colorful nebula in front of him can be locked as a certain nebula in the Milky Way, then Lu Yu will not be far from returning to Earth!

"The color of nebulae depends on the chemical composition and the amount of nebulae being dissociated, and since most of the interstellar gases are hydrogen that can be dissociated at relatively low energies, many emission nebulae are red. If there is a higher energy that can cause other elements to be free, then both green and blue clouds may appear. By studying the spectrum of nebulae, astronomers can deduce the chemical elements of nebulae. Most emission nebulae are 90% hydrogen, with the rest made up of helium, oxygen, nitrogen, and other elements. ”

"The nebula in front of you is colorful, which means ........."

"All the super quantum computers in Base Zero have been put into the comparison star map!"

"At all costs, find a control sample of the nebula in front of you!"

Base Zero is rarely running at full capacity, and now the energy at the disposal of a single base is higher than the energy of all the countries on the Blue Star combined!

If Base Zero wants to take over the global network, it only needs to connect the computing power of the base to the Internet, and it can instantly dominate the network that now involves all human life.

And now, this huge computing power is running at full strength, just to find a possible star path for Lu Yu to return to Blue Star.

No. 7 is also running at full strength, and it doesn't matter to her whether she returns to Blue Star or not, but that is Lu Yu's wish, then she will do her best.

In fact, there are a lot of nebula observation records in the human database, especially after the establishment of the forward base, in order to find the route of the unknown fleet in deep space, a large number of observation telescopes have been built.

If there are no bright stars in the vicinity of the gas dust nebula, the nebula will be dark, i.e., a dark nebula. The dark nebula does not emit light and has no light for it to reflect, but it will absorb and scatter light from behind it.

This type of nebula is inherently the most difficult to observe, and even so, tens of thousands of new dark nebulae have been discovered by relying on the forward base.

And those luminous nebulae and reflective nebulae, not to mention, have too many of them, and they have already asked Professor Mao to name them, and simply let the AI number them by themselves.

And now, they've been turned out one by one, scanned over and over again!

“.…..”

Seven was the most arithmetic, and she stopped first in silence.

When Lu Yu saw her appearance, he instantly understood, maybe the galaxy in front of him was not ....... Milky Way.

"Isn't it just a wasted jump? What's in it? ”

"We were jumping for five years in a row, and I knew it wasn't that easy to find the Milky Way."

"Before I met you, random space jumps had to disorient me, and the universe is so big......."

Lu Yu had already withdrawn from virtual reality and was waiting for the result in his living quarters, but now the expected feedback made him breathe a sigh of relief.

Touching No. 7's white hair, Lu Yu comforted her instead.

Despite coming with expectations, Lu Yu also understands the universe. (This chapter is not finished!) )

Chapter 30: The Colorful Nebula

It's so big, it's not that simple to get back into the galaxy.

It took several hours for the feedback from Base Zero to arrive, and Professor Han's look of regret spoke for itself.

But after all, it's just a waste of two space jumps, jump back to the folded space to toss that huge spaceship and the Zerg, right?

Lu Yu thought so, and No. 7, who had finished comforting but was still lying in his arms, suddenly projected a holographic projection in front of his eyes.

It is a neutron star that is constantly emitting periodic electromagnetic pulse signals, and it has a resounding name - pulsar!

The pulsar's position is beyond the Prismatic Nebula, but its powerful electromagnetic pulse signal is still transmitted here.

This is a normal astronomical phenomenon.

But after Seven's analysis of those periodic electromagnetic pulses, the abrupt content was revealed.

"Hello, civilization receiving information."

"Please guide us in making ice cubes, okay?"
