In this world, the sky is dark, and a few black crows are croaking in the sky.

The sun will never rise from the east. Here is the eternal night, with only a starry sky, emitting a dim light above your head.

In order to adapt to low-light environments, everyone's eyes look bigger than the real world, especially girls, like characters in the anime world, with big and beautiful eyes. The main reason is that the larger the pupil, the more sensitive the perception of light.

"The steam era, there is no daytime, a strange world..." Zhang Yuan vomited a breath of turbid air in his chest.

He has lived here quietly for 18 years. At the beginning, just like the previous world, he had a certain tendency to autism. However, this condition has completely improved with the awakening of self-awareness.

Looking up at the stars in the distance, he easily recognized the so-called "Polaris".

The starry sky here is completely different from the one on the earth. "Polaris" is just a similar noun in astronomical and is widely used in navigation.

There are still no superpowers in this world, magic, what he calls "golden fingers", which is a very good aristocratic origin, a strong body, and some mechanical design drawings about the steam era.

Well, in addition to having a good background, this kind of "golden finger" is really better than nothing. Zhang Yuan even felt that the various knowledge in his mind was much more effective than mechanical drawings.

He turned his head and looked at a crescent moon directly above. The shadow of the moon was actually because the earth itself blocked the sun's light.

"In other words, this planet is still a sphere, so the outline of the moon being blocked is an arc shape."

Due to the lack of sunshine, the number of people that this land can support is not large. Judging from the current known information, the population of several continents in the world is only 100 million.

Most people don’t live well.

There is a small globe on the table, which was made by Zhang Yuan based on local navigation images, half dark and half bright. Due to the harsh environment of the planet itself, the area that humans have explored is only one-tenth.

"There is no daytime in this place, only night, so there is only one possibility... This planet has been locked by the tidal tides of the central star, so the sunrise side is always daytime, and the other side is always night. We humans live at night."

Tidal locking is a very common phenomenon in astronomy. For example, the moon always faces the earth on the same side. The time when a tidal locked celestial body rotates around its own axis is equivalent to an orbital period.

So, this planet is actually illuminated, and at least half of the areas have illumination.

So, why don’t humans live in the light belt of the planet?

The reason is that the planet is too close to the central star, and the side that is exposed to light seems extremely hot. Humans cannot survive under the high temperature in the light belt, and can only live in this dark side with a relatively suitable temperature...

"What a tragic world!"

However, according to the logical perspective of physical rules, there must be no shortage of such tragic civilizations in the universe...even if it is currently just a virtual world.

Zhang Yuan was thinking about what his arrival could change this civilization...

For him, it was already a habitual thinking.

"Sir Earl, you should prepare for the dance party held by Duke Valta... The time has come." The elderly deacon interrupted Zhang Yuan's thoughts and made a unique aristocratic etiquette.

"Okay, thank you for your reminder." Zhang Yuan nodded, put on his dress and leather shoes under the servant's service, and then quickly boarded a steam locomotive.

In this world, due to his good reincarnation, he is already an "elephant". His cheap father died a year ago due to a shipwreck, and then the queen awarded the hereditary title to Zhang Yuan... This should be considered part of the "Golden Finger", which allows him to live a very wealthy life without hard work.

The engine was "rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-rake-

This is the city of Giant Rock, the most eastern city on the mainland. The temperature is about 24-26 degrees Celsius all year round, which is very suitable for human habitation - the only disadvantage is that there is no sunshine.

Warm currents from the western light zone bring endless streams of fish and algae, and are also the food source for the residents of the city to live on.

Starting from the Rock City, the more you go west, the closer you get to the light, and the hotter the weather.

Five hundred kilometers westward is the junction of light and darkness - the dusk zone of this planet. In the dusk zone, the temperature is as high as 40 degrees Celsius. Humans can barely survive in this area, but they are quite uncomfortable. However, many animals and plants can live very happily.

No matter how unsuitable the dusk zone is, with sunlight, it can naturally grow various plants, so it becomes a very important plant production base in the west of the mainland.

Some not very wealthy people and all kinds of slaves endured the high temperature and farmed in the dusk zone area to make a living. Zhang Yuan's family also had a small area of ​​territory in that area. Of course, he just knew this and had never seen it in person.

On the contrary, the more you start from the Rock City, the colder the weather will be.

The continents of this planet are sparse. The east is an endless ocean with annual temperatures around minus 20 degrees Celsius. The coldest place can reach minus 100 degrees Celsius, forming a thick layer of ice, which is the so-called forbidden zone for humans.

"call--"

Humans are too difficult.

Zhang Yuan exhaled gently, rubbed his hands, and shook his nose. He could smell the unique smell of coal burning from afar.

Coal, the most precious substance in the world without light, means energy, and light.

Without coal, there would be no industrial revolution. Without industrial revolution, human life would be even more miserable. At least now, 100 million people live in the continent and islands. It is said that in ancient times, the entire continent could only live in millions.

The steam locomotive was slowly moving on the road. The road surface was paved with residue burned by coal and mixed with asphalt, emitting a faint smell of sulfur.

People come and go on the streets, and gas lights on the roadside are blooming with dim light. Many people cannot light gas lights at home. The light source on the street is the only light source for them, and some children are doing homework on the roadside.

Every household has put some plants like bean sprouts in front of the door. This kind of negative-loving plant can grow with just a little light source of gas lamps. For ordinary people, vegetables are precious. Anyway, the light source is provided by the government, so why not do it?

"Rum from the Gar Islands! And the freshest 'Antima' ingredients, everything is available!"

"The pilosula grass that I just caught is fresh!"
