Gu Chuan remembered that on Earth, navigators who sailed far away were usually excellent astronomical discoverers.

The Great Magellanic Nebula, for example, was first recorded during the Arab voyages, and was later accurately described by the globetrotter Magellan, who determined that the two seemingly sticking together were actually two nebulae, not one.

The connection between navigation and astronomy is straightforward. First of all, there are very few landmarks that can be used for positioning on the endless water, and navigators can only use astrological observation. Secondly, the starry sky that can be seen at sea is not the same as the ground at other latitudes and longitudes. The last reason is that life on a ship on the surface is very boring, and there are very few things that can be done.

For our travelers, they have a needle that always points in one direction, and they will never get lost.

They don't know what it means to be bored.

But it's soon to know.

The shipyard's underground intake is directly connected to the edge of the Netherworld, where the cogwheel man has dug a diversion channel over the past few years. The Netherworld liquid had long since filled it, and the boundless water rose magnificently over it, turning into a hazy cloud of smoke and changing into many strange shapes.

The dispersion of matter and matter, continuously stacked above the Netherworld, hanging magnificently over the heavens and the earth, like a tower, is the largest tower-like cloud among the three types of clouds that Gu Chuan observed.

The base of the Cogwheel Man is beneath such a tower-like cloud. Occasionally, the light in the tower-like cloud will shake the entire atmosphere, causing it to glow brightly. The swirling whirlpools, the sweeping winds make everything unclear in front of you form waves of amorphous matter, as if you are not in the water or the clouds, but in the land of ghosts and ghosts.

"But there's no need to worry too much, at least it's a breeze to get out of the port."

In the face of wind and rain, Zai Yi is absolutely confident.

Death or Life carries not only the wishes of two strangers, but also the long-cherished wishes and beliefs of the Gear People for generations.

The rush at the inlet could not hinder the progress of the Death or Life at all, and only turned into waves and clouds of awe, and countless broken droplets of water in the midst of sudden and continuous collisions. The moment the water droplets lose their connection with each other, they quickly evaporate, forming a mighty cloud and mist, which is poured into the sky, and even the death or life cry struggling in the water seems to rise on the spot and crash into the heavens and the earth.

The waterwheel and sails at the bottom of the ship made a burning crackling sound, struggling to float in the liquid, pushing the water towards the place where there was more gas.

People are in the boat, a wind and rain.

The young man stood unusually composed, standing in front of the outside world reflected by the glass wall, standing still. He saw large expanses of clouds condense into actual droplets of water, sticking to the exterior of the ship, causing the light reflection of the peculiar glass metal to fail continuously. And then the world suddenly went gray.

The world is rough, while nature is unfathomable.

The Dead or Alive bounced upwards in the water, causing the hull to stagger, stumble and bump, up and down and from side to side, between the waves. The sleeping box where the kiwi egg was located slammed into the glass-like wall, intercepted by a substance that was essentially metal. It cautiously poked out its little eyes and teased:

"You've finished reciting the poem, but why haven't we gone out yet?"

The immovable young man showed his white teeth and said with a smile:

"Now it's the aftermath of poetry!"

Before he could finish speaking, all the water droplets that had condensed on the exterior of the hull turned into mist with the wind. And the hull of the ship completely broke through the tide of the gaseous and solid matter, and climbed above the dark underworld, and walked into the fog.

And the clouds suddenly disappeared. The surroundings were gray and vast, and it was impossible to see clearly. Everything is in this mass of colored opaque matter, drifting and crawling in the interface between the two worlds.

There is nothing in the near distance, and there is nothing in the distance.

The travelers watched from the boat, and after the stability of the ship, they finally breathed a sigh of relief.

The waterwheel and sail were smoothly transported above the netherworld, and the Gear Man did not make any mistakes in his technique.

"We're out of the base?"

Gu Chuan asked.

Answer:

"That's right, that's right."

There are many faint spots on the windows, which are condensations of liquid particles on the outer side, which adhere to the hull. The field of view is foggy, and the giant telescope has become an important observation method site.

"We're in the No. 6 tower cloud right now." Chu Yun waved the glass book in front of him and spoke out at the right time, "The book says to avoid climbing to the second layer of Cloud Six. ”

The Cogwheel Man has been observing the Netherworld for a long time. Naturally, they are also more interested in clouds than young people who are just beginning to classify clouds.

The No. 6 tower cloud is the super-large cloud body that separates the base of the Gear Man from the direction of the Netherworld.

According to the observations of the Cogwheel Man, the height of the No. 6 tower cloud is 5,600 meters, and it is divided into four main layers and three gradient layers sandwiched between the main layers. The height of each main floor is about 1,000 meters.

Due to the fluid-resistant nature of the waterwheel and sail, it is possible to climb abnormally on the surface of the netherworld where it is not clear to distinguish between the liquid and gaseous states.

"It's up to more than a kilometer." Zai Yan added calmly, "Because the waves of the Netherworld that can be observed are at most kilometers high. In other words, a kilometer on the Great Wasteland Alignment is the material nature level of the Netherworld that will liquefy and vaporize at any time. ”

"Then it would be nice to follow what we wanted at the beginning."

The waterwheel and sail are not unmaneuverable, but they rely on control of the growth of the waterwheel and sail at the bottom of the hull. If you want to sink, you need to suppress the growth of the waterwheel sail in advance. If you want to lift the boat, you need to increase the growth of the waterwheel and sail.

The Gear Man's approach has long been clearly written. Travelers just need to be prepared and do everything the book says.

Both Hatsuyun and Zaiyun nodded.

Mr. Dandan, who felt that this matter had nothing to do with him, lay in the sleeping box and refused to come out.

The light and shadow inside the ship are bizarre.

The glass walls reflect the fog outside the ship, while the ceiling and floor inside the windows glow. Mr. DanDan is ready to continue to sleep beautifully. Its sleeping box is its whimsical idea to make the tall box with self-propelled wheels and manipulators used by the gear man to carry the equipment its home.

Then, it was covered in warm, gentle mats in the box.

It's the equivalent of walking around with a movable bed all the time.

"Mr. Chaos, who is already very comfortable, is this the treatment of a polite and pursuing person!"

It thought to itself and rolled over.

Who knew that the shadow of the young man suddenly came and covered its head.

"You're going to be a part of that, too!"

"What's the matter? I don't know. ”

Mr. Dandan, lying calmly on its warm bed, didn't want to do anything.

Gu Chuan laughed:

"But you're on this ship, and you can't go anywhere, can you? If you don't do a good job, I'll probably lock you up and save you from wasting our few resources. ”

The strange creature of the wilderness poked out half of its head, and its incredibly small eyes.

"It's just a small room with nothing......"

Gu Chuan didn't need to finish speaking, Mr. Dandan already knew the meaning of this young man's self-evident threat, and he was forcing himself to cooperate.

"It's immoral for you to do this, and I don't have anything special to lose! Except for ......"

Gu Chuan patted its bed, his fingers clapping its warm little quilt. Of course, the quilt is not changed by it - it doesn't even have a hand! Rather, the young people took the uniform and washed it with their garments. In the future, there is a high probability that the sleeping box will also rely on young people to sort out and wash it for it.

However, this is not necessarily the norm, maybe in the future they will develop some new roles of some equipment of the gear man, maybe there will be no need for human labor.

This egg, which is eager to be eaten immediately and is not afraid of death, is entangled in pain.

"You've figured it out." "After that, it's up to you to perform."

After Gu Chuan finished speaking, he patted the round head of the strange egg, and then turned around and left the sleeping box. The ship was still too big, and it was too difficult to rely on a few people to maintain it, and they had very little leisure time after all.

I was probably attracted by the movement here. The assistant gear machine spun its four propellers and flew all the way to the top of the sleeping box, looking at the strange creatures that puzzled it inside.

Mr. Dandan fell on his bed, opened his little eyes to the heavenly thing, and said:

"What do you think I'm doing?"

The gear machine vibrated its propeller, made a strange noise, and tilted in the air.

"What's so funny about you robot dog not being idle all your life and being a slave to the maker? I have not served them now, and even if I did, I would not have worked diligently for my master like you, but ...... Well, I'm giving alms, well, a servant who washes my quilt. ”

Mr. Dandan, with his little eyes open, leaned on his sleeping box, and said righteously.

The gear machine did not bother with it, but flew away in the direction of the load.

Gear people have a higher priority for it.

And Zai Yi is about to send a new task to this little thing - to monitor the temperature.

Now, put aside the strange egg creature and get back to us travelers.

The first day of the journey into the Netherworld was peaceful.

The main phenomenon is the irregular decrease in the outside temperature. But this incident has attracted enough attention from young people with excess energy.

The irregular decrease in the outside temperature is a strange phenomenon within the tower-like cloud. The Dead or the Living was cautious, and as it walked on the outer edge of the bottom layer of the tower-like cloud, countless water droplets suddenly condensed into something liquid or solid, crackling and smashing on the Dead or the Alive.

The continuous sound reminded Gu Chuan of the time when he was at home listening to the rain outside.

But if you look for a source, you can't find it.

Because all the water droplets and ice were formed in the mist, it was somewhere in this tower-like cloud that suddenly began to condense and condense, forming non-gas falls.

He used his telescope to look at the space many kilometers away, and he could only see the clouds and mist, and there was no trace of dispersion.

"Is the change in temperature consistent with the original observation of the Gear Man?"

He asked.

"Didn't you read the glass book?"

Zaiyi was unpacking the boxes, and he had the gears transport them to the specific rooms. Hearing Gu Chuan's question, the lion-headed gear man raised his head and said:

"Yes. The irregular change in temperature is mainly due to the properties of the netherworld. Within the clouds, the change in temperature is irregular. ”

However, due to the conduction of heat, between the clouds, the atmosphere with scarce netherworld matter is also affected by the temperature changes of the clouds, and sometimes sets off terrible winds.

The wind swirled between the clouds, changing the shape of the clouds like a huge whirlpool, so that it was difficult for the Dead or the Living to take a straight path.

And young people can't control this, and they can only watch them get farther and farther away from the original world.

And they soon discover that there is very little they can do on board.

In addition to those things that can be done by one person and can be done by changing to a gear machine, there are only maintenance, learning and exercise.

Their lives suddenly became monotonous.

"I don't know when we will be able to pass through the Netherworld, and if we do, where will we go?"

The storage room for glass books, in addition to the Arazuka set, is now filled with other glass books brought out of the base of the Gear Man, and according to human habits, it is an excellent study room. Gu Chuan set up a table and a chair as his study.

An entire wall is like a window that reflects the misty and clear scenery of the outside world.

As he was talking to himself, Hatsuyun just pushed the door and entered, clenching the moth pin on his chest. The girl said curiously:

"Will it reach what you said in that pamphlet?"

The young man choked up.

"Well......" he was thinking about how to answer, "I said it, I made it up." ”

Hatsuyun flashed his eyes.

The young man continued:

"That's what it means, but maybe all this I'm making up may be true in some places, maybe it's okay? After all, the world is big! There are no surprises. ”

The girl fell into deep thought, and felt that what the young man said made sense.

It was only a few days later that she realized what a cunning and meaningless answer this was during a conversation with Mr. Dandan.

It is worth mentioning that the process of leaving the No. 6 big cloud was uneventful.

When leaving, the airflow and shipping were very smooth. The Dead or Alive was raised to a high altitude of almost tens of meters by the liquid gaseous mixture of the No. 6 Great Cloud. This is a dangerous thing, because once the No. 6 cloud comes out, the thinning of the nether matter will cause the hull to plummet, resulting in damage.

But Mr. Dandan, who was on duty at the time and discovered this in time, woke up the others and used the equipment of the gear man to inhibit the growth of the waterwheel and the sail.

So, a few days closer to leaving, the Dead or Alive descended smoothly and reached a low enough place to sail smoothly out of Cloud No. 6.

If it is like the sea, it is already far from the coast.

But the clouds in the sky remained, and the moon could not be seen. The young man originally wanted to observe astronomy, but his idea fell through. He came to the stern of the ship with regret and observed where they came.

I only saw the boundless wilderness in the layers of dark clouds, like a straight line.

They moved away from the straight line. And the straight line, like Sunset City, disappeared behind the mountains, disappeared behind the eternal clouds.

As for their fate, they are also far away from the fate of the Gear People, and the fate of the world gradually penetrates into the realm that no one knows.
