In the end, Zhou Sen's focus fell on the West Asian exploration spacecraft.

According to historical records, the first interstellar immigrants of the West Asian Empire arrived on this planet similar to the Earth on a West Asian exploration spacecraft, and then multiplied and developed a modern civilization on this planet.

Spaceship!

With the spaceship, you will be able to leave the planet.

As long as the West Asia exploration spacecraft can be lifted into space, Zhou Sen is sure to find a route back to the five star fields, because the West Asia exploration spacecraft is from the Milky Way, and the Milky Way itself is one of the five star fields, and it is easy to find the interstellar coordinates of the five star fields.

Zhou Sen guessed that the star should be in the Milky Way.

Although the five star fields include the Milky Way, this does not mean that the human beings in the five star fields have explored every corner of the five star fields.

According to some popular science data, the Milky Way is the star system where the solar system is located, and the ancient earth is in the solar system, including 1500~400 billion stars and a large number of star clusters, nebulae, as well as various types of interstellar gas and interstellar dust, black holes, and its total visible mass is 210 billion times the mass of the sun.

Most of the stars in the Milky Way are concentrated in an oblate sphere of space, which is shaped like a discus. The protruding part of the oblate sphere in the middle is called the "nuclear sphere" and has a radius of about 7,000 light-years. The middle part of the nuclear ball is called the "silver core", and the surrounding area is called the "silver plate". Outside the galactic disk there is a larger, spherical region where there are fewer stars and less dense, known as the "galactic halo", with a diameter of 70,000 light-years.

In the past, the Milky Way was thought to be a spiral galaxy like the Andromeda Galaxy, but the latest research suggests that the Milky Way should be a barred spiral galaxy.

90% of the Milky Way is made up of stars. There are many types of stars, and according to their physical properties, chemical composition, spatial distribution, and motion characteristics, stars can be divided into five star families. The youngest extreme star family, I. Stars, are mainly distributed in the spiral arms of the galactic disk; The oldest Extreme Constellation II. stars are mainly found in the galactic halo. Stars often clump together. In addition to a large number of binary stars, more than a thousand star clusters have been discovered in the Milky Way. There are also gas and dust in the Milky Way, which account for about 10% of the total mass of the Milky Way......

……

Among the five star fields named by mankind, the Milky Way is the first galaxy explored by mankind, but mankind has explored the Milky Way less than one-tenth or two.

In fact, not only the Milky Way, but all human exploration of known galaxies is very limited, because, when human beings have not broken through the space jump technology, it is equivalent to swimming in the pond all the time, after all, for those who move tens of thousands of light years, human technology cannot uncover the mystery of the universe at all.

It wasn't until the human spaceship was able to make space jumps that humans could swim in the ocean and truly enter the interstellar age, when the distances of tens of thousands of light years could be reached in an instant.

However, the breakthrough of space jump technology still makes it impossible for human beings to explore the universe in a carpet way, because the distance of a space jump is hundreds of thousands of light years away, and tens of thousands of light years away, and there are many unknown regions in the distance of this jump.

Zhou Sen speculated that the West Asian Star did not actually leave the Milky Way, because the ancient Earth's spacecraft did not have the ability to leave the Milky Way.

The most likely thing is that the West Asian exploration spacecraft should also be near the solar system.

Because the West Asian exploration spacecraft comes from the ancient earth, then there must be a cosmic star map of the solar system on that spacecraft, and as long as there is a cosmic star map of the solar system, then as long as you find a route to the five star fields according to the cosmic coordinates of the solar system......

……

Soon, Zhou Sen sorted out that now, he needed to find the antique spaceship.

West Asia Museum!

There is no need to look for that antique spaceship, he is in the West Asia Museum, and that spaceship is still the biggest city landmark in the big city of West Asia so far, not one of them!

It seems that it is not difficult to find the West Asian exploration spaceship, the difficult thing is to get into that spaceship and then let that spacecraft lift off into space.

Launch!

The corners of Zhou Sen's mouth flashed with a wry smile, it is not easy to let an antique spaceship weighing tens of thousands of tons lift off into space, in fact, it is impossible to lift off by the spacecraft itself, because the large exploration spacecraft built by the ancient earth back then were all produced in the ancient earth, and then assembled in the space station, because the ancient earth technology level at that time was still very low, there was no anti-gravity system, and it was impossible to build an engine that could lift a spaceship of tens of thousands of tons.

What to do?

Making an anti-gravity system?

Zhou Sen's head suddenly became bigger.

For Zhou Sen, the anti-gravity system is not a high-tech, this technology is very mature in the five star fields, but this is not the five star fields, and it is not possible for him to produce this thing alone, because it is a huge project.

The anti-gravity system is composed of countless anti-gravity modules, however, this does not mean that the anti-gravity system is small, in fact, the anti-gravity system is very large, and the single module structure that can hold up the starship is more than thirty tons, and according to the description in the history books, the West Asian exploration spacecraft needs at least twelve anti-gravity module structures to be able to lift it off.

Twelve thirty-ton anti-gravity modules, which add up to a total of three hundred and sixty tons.

Three hundred and sixty tons!

If it is three hundred catties, Zhou Sen can also use the method of refining to produce some spare parts, even if it is three tons, he can also find a way to overcome the difficulties, but thirty tons of anti-gravity module components is not something that a refiner can do at all.

Thinking of this, Zhou Sen suddenly understood the reason why some refiners were reluctant to refine some large-scale magic weapons, because the productivity of individuals had limited the refiner and could not replace technology.

If there is no other way to leave the planet, then the only way is to find a factory to produce twelve anti-gravity module components.

Who to look for?

Zhou Sen was once again in a state of anxiety.

If this is a normal planet, with the current level of technology, it is completely possible to produce an anti-gravity system, but the problem is that this is a planet where technology is suppressed, where scientific workers and teachers are being persecuted, and religious sects dominate this society.

In addition, the production of twelve anti-gravity module structures is not a small project, but a vast project, involving a wide range of fields, energy, chemical industry, smelting, electronics, etc., is not to find a small workshop to complete, requires a lot of high-tech factories to cooperate......

……

Zhou Sen believed that if he built twelve anti-gravity module structures in the current atmosphere, it would definitely attract the attention of the intelligence system of the religious sect of the West Asian Empire.

In addition, even if all goes well, it would be impossible to transport the twelve anti-gravity system module structures to the museum and install them on the West Asia Exploration Spacecraft.

What to do?

"Woo woo......" Just when Zhou Sen was racking his brains to find a way, suddenly, there was a furry thing rubbing under his feet, and when he looked down, it was the Howling Sky Dog that was rubbing his legs.

Wrong!

How did the whistling dog turn white?

"Are you a whistling dog?" Zhou Sen suddenly bounced up as if he had been shocked, and Tang Dao also held it in his hand, looking at the white dog with a vigilant expression.

"Woo woo...... "White Dog nodded repeatedly.

"Then you come in!" Zhou Sen touched the golden god.

The white dog turned into a puff of green smoke with a depressed face and disappeared into the golden god.

"Damn, it's really a whistling dog. Come out and come out, I'll get you meat to eat! ”

Zhou Sen summoned the Howling Dog in surprise, brought the pot of meat that had been cooked, and then took a closer look while the Roaring Dog was eating the meat, and he found that the Roaring Dog was black all over except for its four legs, but now, except for its four legs, the rest of the place has turned white.

The ancients did not deceive me!

It's no wonder that the myths and legends of the ancient earth describe the Howling Dog as white, and it turns out that the fur of this guy can change color.

I wonder if there is any pattern to this discoloration?

Could it be that it's black during the day and white at night?

Zhou Sen watched the roaring dog gobble up for a while, and then, got up and walked to the window, the heavy rain outside had stopped, and a few stars were revealed in the originally dark sky......

……

Zhou Sen returned to the couch, once again racking his brains about how to get out of this damn planet.

Zhou Sen didn't have any feelings for this planet, he just wanted to get out of here as soon as possible.

Will that ancient interstellar merchant ship come to pick him up?

Zhou Sen immediately shook his head, he didn't think that those robots would come to pick him up, in fact, that interstellar merchant ship didn't seem to be controlled by those robots.

In addition, Zhou Sen would rather be trapped on this planet than board that weird interstellar merchant ship again, after all, if he gets on that ship, it is very likely that he will be made into a specimen.

West Asia Exploration Spaceship!

Zhou Sen found that no matter what he thought, in the end, it still landed on the West Asian exploration spacecraft.

In its current form, if you really want to use the West Asian exploration spacecraft to return to the five star fields, the only way is to subvert the West Asian Empire......

……

"Woo woo ......" Just when Zhou Sen roared in a low voice, suddenly, the Howling Sky Dog, who was lying lazily on the ground after eating the meat under his feet, suddenly raised his head, and let out a slight low roar from his mouth.

Someone!

Zhou Sen tiptoed to the curtain and gently opened the curtain to observe.

Before, Zhou Sen had turned off the lights in the hall, that is, now the entire wooden house was pitch black, which was conducive to observing the situation outside.

Tang Xue.

Tang Changfeng.

When Zhou Sen saw his sister and brother slowly approaching in the dark, Zhou Sen couldn't close his mouth.

These two people are really haunted!

Zhou Sen didn't want to entangle with them and decided to evacuate to another place, but just as he got up, he saw a mechanical ornament hanging on the wall, which was made of countless gears, giving people an extremely sophisticated feeling.

Technocracy!

Tang Xue is a science and technology school!

Tang Xue ventured back here, indicating that the owner of this wooden house is also a science and technology school.

If you build an anti-gravity system, wouldn't you find the right master when you look for a science and technology faction? With the support of the tech faction, things would be much simpler, after all, they are a huge organization, and it should not be difficult for an organization to produce a dozen anti-gravity system modules.

Zhou Sen sat down slowly, letting the Howling Dog go out through the hole in the back to keep watch......

……

After a slight bang, the lights came on.

Immediately, Tang Xue and Tang Changfeng looked at Zhou Sen sitting on the sofa with a dull expression.

"See you again, please be seated." Zhou Sen got up and poured himself a glass of water, and said with a look on his face.

"Who let you in?" Tang Xue finally reacted, pulled out her gun and pointed it at Zhou Sen, and said angrily.

"Why can't I come in?" Zhou Sen shrugged.

"You ......"

"Do you want to overthrow the rule of the West Asian Empire?" Zhou Sen interrupted Tang Xue.

"Ah......" Tang Xue's face changed color, she didn't expect Zhou Sen to dare to say such a rebellious thing, which surprised her a little.

"I have a way." Zhou Sen said lightly.

"It's up to you!"

"Yes, by virtue of my being a scientist!" Zhou Sen said word by word.

"Scientists? Hahaha......" Tang Xue smiled and blushed.

"Isn't it funny?" Zhou Sen said lightly.

"Okay, since you said you are a scientist, then I'll test you a few questions!"

"Say it."

"Why is the sorbet bubbling up?"

"Ah...... This...... Just this question? Zhou Sen had a petrified expression on his face, he thought that Tang Xue would ask some esoteric scientific questions, but he never dreamed that he would actually ask these little things about life.

"Don't talk nonsense, answer me!" The gun in Tang Xue's hand did not move at all.

"The sorbet is bubbling because there is a lot of invisible water vapor in the outside air, and when it encounters a very cold sorbet, it will liquefy into drops and surround the sorbet, which looks as if the sorbet is bubbling." Zhou Sen could only answer honestly.

"Why do sunflowers always look towards the shining stars?" Tang Xue's bright eyes stared at Zhou Sen.

"The rhizome of the sunflower contains a wonderful plant auxin, which is very afraid of light, once exposed to sunlight, it will go to the backlit side, and at the same time it will stimulate the cells on the backlit side to multiply rapidly, so the backlit side grows faster than the light-facing side, so that the sunflower has a phototropic bending."

“…… Why do the stars twinkle and twinkle? Tang Xue didn't expect Zhou Sen's answer to be so fast, and after thinking about it, she asked a question.

"On a planet inhabited by humans, there is an atmosphere that is separated between us and the stars, and when the starlight passes through the atmosphere, it is affected by the density and thickness of the atmosphere. The atmosphere is not absolutely transparent, its transparency will vary according to the density, so if we look at the stars through the atmosphere from the ground, we will see that the stars seem to be flashing. In order to gain Tang Xue's trust, Zhou Sen could only answer these mentally retarded questions honestly.

"I ...... I'm going to have a problem. Do you know how to solve equations? Tang Xue looked at Zhou Sen in surprise, she was a little reluctant to give up, and decided to come up with an equation that the West Asian Star science community couldn't solve.

"A little bit!"

"Then I'm out." Zhou Sen's calm expression made Tang Xue very uncomfortable, she always felt that this guy was too conceited, and she decided to embarrass him.

"Come out."
