Recently, Ian has calculated the speed of light.

It's not a difficult thing to do, as long as you have enough high-quality lenses and stable mechanical switches, you can get high-quality measuring tools from any source in Ian's current capacity

The result was actually quite amazing: the speed of light was normal.

Although the results are not 100% equivalent to the speed of light on the other side of the Earth, they are generally within an acceptable range of error.

The gravitational constant test with the Cavendish torsion scale also proves that the gravitational constant of Terra is exactly the same as that of the Earth's universe.

At this point, there is nothing surprising, after all, the Terra universe is currently a material world on most levels, and almost all phenomena are consistent with the Earth universe, if not the same universe, the two are at least an extremely similar similar universe

But the problem is that the mass of Terra is very large.

Terra is about 1.7 times the mass of Earth, the gravitational pull is indeed greater, and the density is normal, but Ian does not feel the difference.

Of course, this does not say anything .... Could it be that the Terra people are too physical to feel the difference?

It doesn't sound like a big deal, all constants are normal, it proves that he is not in a universe where everything is very different from the earth, and it also means that his knowledge from the earth can work, and Ian should be happy.

But in reality, this is confusing to Ian.

"A universe with essents and psionic energy, you tell me everything is the same?"

Ian is incomprehensible, essentia psionic energy is something that can directly change the physical constants in the area, with these two, psionics can manipulate gravity and strengthen electromagnetism, sublimators can use their own bodies to carry nuclear furnaces, essentia structures can modify biological bodies from organelles and even more subtle things, change the properties of most matter, and create all kinds of stable sublimated metals with different functions...

Their very existence means "abnormal" - measurable numerical results are all normal!

"No, it's my problem."

In the laboratory, Yi Si shook his head slightly, and he understood the question of his thinking: "Perhaps, the problem may not be why the universe with essents and psionic energy has the same constant as the earth. “

"It's because of essentia and psionic energy that this universe can be the same as the earth's universe."

This may be the real result.

In order to obtain data that can be truly compared with the Earth universe, I am afraid that it is necessary to create an aether vacuum.

Using pure essentia and rejecting natural psionic energy, a pure "space bubble is the core technology of the aether furnace inside, and the inside of the cavitation bubble is very close to the ether vacuum when the "energy storage" function is not turned on.

Testing there can at least measure the normal speed of light under the interference of passive psionic energy, and the gravitational force is too macroscopic to obtain interference-free data.

But on the other hand, if the speed of light obtained in the aetheric vacuum is different from the speed of light obtained in essentia psionic spacetime, then there is a high probability that constants such as gravity can be distorted by essentia psionic energy.

At this point, there is no need to continue. No matter how precise and strict the experimental conditions are, they will not help the development of today's productive forces, but simply satisfy Ian's own curiosity.

So, after finishing his initial calculations, Ian shifted his focus elsewhere.

For example, he had the new agricultural system in mind.

Xiahui Lake.

Ian inspects the newly built farm building.

The hydroponic three-dimensional farm building on the shore of the lake is now beginning to take shape, and the unfinished high-rise building is already 70 meters high, and its estimated height will exceed 100 meters, almost like an alchemy tower.

The leader of the foreman is named Gera, a soil sublimator, his true form is not strong, he is the same style as the Wave Singer, born from the bloodline of the steel-clawed giant mole, "road shaper", with a strong ability to manipulate soil and rock, and explore rocks, mountains and buildings.

The world of Terra has concrete and cement, and the architecture is also very developed, otherwise those high-rise spires and super-giant buildings that are often hundreds of meters high would not have been able to be built.

Even if it is all built by the sublimators themselves, then the daily maintenance can never be just

Sublimator, right?

Captain Gera was also a professional who participated in the construction of the alchemy tower in Nauman City, and after the construction of Nauman City, he got enough experience to become independent and lead the team to make a list, and his life was quite nourishing.

After all, in Terra, as long as the sublimator of the first energy level does not think about the next promotion, nor does he think about fighting for power and profit, but just wants to make money, he can always live a very nourishing and relaxed life.

Captain Gera respectfully took Ian to inspect what he thought was a "strange" building.

To be honest, after so many years of construction in Nanling, he has never heard such a strange request: a high-rise building that is completely light? Is there a well-developed water circulation and lighting system inside?

Obviously there is good arable land next to it, but it turns out that you have to farm in the building?

No matter how you think about it, it feels strange, and even feels like it's too much, but the thing that Gera knows best after so many years of life is not to express an opinion on what she doesn't understand: is he smart or is this lord who can enjoy the elite alchemist credential at the age of sixteen smart?

Just learn it!

This time he took Ian to inspect his construction results, and it was also an opportunity for Captain Jayla to learn something special from Ian, so he was very enthusiastic.

And Ian can also see Jara's thoughts, he doesn't mind, and it can even be said that he hopes that Jera's thoughts will understand.

After all, he didn't study civil engineering, and the experienced Gera was the professional Ian was in need, and if he could understand the architectural concept of the farm building and the future breeding building, he would definitely be able to come up with a more sonic design than he did.

The farm building is right in front of you.

The towering gray building stands in the sunlight, and the lake on the side reflects the golden light, and it is cylindrical in shape, with only the most basic skeleton.

The full version of the farm building should be covered with glass to ensure adequate light, and the interior should be fully illuminated, with a strong lighting system that will allow the building to glow at night, like a glow stick.

The concept of vertical farms and ranches has long been popularized on Earth, and in Ian's time, not to mention the Earth, at least most of the food sources in space colonies and lunar bases were such hydroponic stereoscopic breeding plants.

The original intention of it was created is to save land, and completely control the light, humidity, temperature, air flow and nutrients and other conditions for the growth of crops, with the smallest space, the fastest speed, the least resources to cultivate the most crops for those fruits and vegetables that mature faster, hydroponic farms can mature more than 12 times a year, and if it is normal farming, at most it is two to three times, and a large amount of fertilizer is applied.

In Terra, such a building has the added benefit of making full use of nature's essentia and psionic energy

Field. The essentia accumulated in the land itself is only a part of the entire natural field, and the three-dimensional farm can be said to have increased the most fertile field that can grow sublimation psionic plants ten times more than ten times out of thin air.

Not only that, a three-dimensional breeding plant is also feasible, a 100-meter-high three-dimensional breeding plant can breed hundreds of thousands of meat animals, can efficiently manage and deal with the manure problem of meat animals, for mountain people who lack arable land and pasture, is the most suitable technology.

Very good.

Ian, who observed the skeleton up and down in the building and confirmed that there was no problem with the quality, nodded slightly and appreciated: "There is no problem with the reserved water circulation interface, ventilation system interface and quality, you have done a perfect job."

Thanks to Amber and Adbert's research, the culture medium specifically for the glow grass has been largely improved and is ready for use.

Although the most important thing in the three-dimensional hydroponic farm is actually a variety of automated conveyor belts to ensure that the crops can receive light evenly, and Ian has not yet researched artificial intelligence, but to be honest, with the current labor cost of Terra, he doesn't really need to let artificial intelligence get started in a short period of time, but pull the skilled growers of those plantations over and let them operate it manually.

For Xia Huiling, it is not to the point where it is necessary to replace human power with artificial intelligence..... You can't leave people without a job!

"Tell Scott to arrange for someone to bring the planters over."

Ian instructed the guards. Half an hour later, a team carried the planting racks from the alchemy workshop area to the lakeside.

Implant racks

It is a huge metal shelf resembling a bookcase, eight meters high and four meters wide, which can carry thirty-two rows of "hydroponic dishes", and one water dish can grow forty crops, in other words, one shelf can grow 1,280 crops.

A complete hydroponic three-dimensional farm building has a total of 12 floors, each floor has a different concentration of natural quality, and can place about 80 to 100 planting racks, in other words, a complete hydroponic three-dimensional farm can cultivate about 1.2 million crops at the same time.

It sounds like a lot, but in fact, even in a small frontier city like Xiahui City, more than 60,000 vegetables will be consumed every day, and the output of one building is only enough for Xiahui City to use for itself for twenty days.

But the problem is that if it were just ordinary vegetables, a hydroponic farm building could produce more than 12 harvests a year - which would cover two-thirds of the needs of Xiahui City.

And Ian spent a lot of money to build twelve hydroponic farm buildings at the same time, which can fully supply the vegetable needs of the entire Xia Hui Ling, and even reserve for export!

It's the time of the food disaster, and although Yisi has affordable food channels, it is good to be self-sufficient, even if only partial.

Of course, after the intense period of the food disaster, the "golden area" around Xiahui Lake will be used to grow Xiahui grass, not ordinary vegetables.

Ian will build these hydroponic farms in other well-lit areas, as well as in the mountain people's territory, to meet the needs of the mountain people, so that they will not be completely tied to the grain production areas of the Agate Stone Plains.

Jera laid hydroponic pipes according to Ian's instructions, and the hydroponic solution prepared using Lake Xiahui water as a substrate showed a strange pale golden color, and most of the glow grass in the laboratory grew well, and the chance of wilting and stagnant growth was much less than that of normal land cultivation.

As long as the temperature and light are well controlled, a harvest in 20 days is not a dream!

Even though there was still sunlight outside, Ian still asked people to turn on the sunlights. A gently rotating conveyor belt rotates the rows of petri dishes so that all the crops in the dish are evenly exposed to light.

"The first batch will be cultivated by the end of next month."

Amber, the bald alchemist, enthusiastically explained to Ian, "Actually, the first lettuce and tomatoes have been grown in the lab--- they taste really good, and they feel crisper and sweeter than what they used to eat." “

"Because it is grown indoors, there are no insects and no weeds, and the nutrients are fully utilized, and although there are algae growth in some of the culture medium, this problem is currently being solved!

"Good." Ian nodded with satisfaction: "If we can eat our local vegetables, the residents will definitely be more at ease, and the number of displaced refugees who can be accommodated will also be larger." ”

"Amber, you're doing a job that benefits the entire territory!"

"Don't dare to be." The alchemist lowered his head, and he said from the bottom of his heart, "If it weren't for your thinking, I might never have imagined that agriculture-related research could be carried out in the laboratory. ”

Except for a very small number of people, how could the high-ranking alchemist care about the development of the peasants?

After determining that Jera's team could quickly and efficiently lay the planting racks and hydroponic pipes, Ian also determined that there were no problems with the design of the farm building and ordered the construction team to continue.

He signed a document and handed it to Captain Geral: "It's the end of the month, I'll go to the town hall to get my winnings." The rest of the refinement and renovation, as well as the other eleven farm buildings, will be left to you.

"Yes!"

Captain Gera was overjoyed - he just did what Ian told him and learned something new, but he didn't expect to have a bonus?

Who wouldn't want to work for a boss who would be generous with bonuses?

And.....

The earth sublimator looked at his "work results" on the side.

By now, he had somewhat understood the lord's thinking.

For farmers, the most important thing for planting is to see the right time and place, bad weather, heavy rain and snow, strong winds and droughts, hail and dust, all of which will interfere with the growth of crops, and the same is true for the land, fertile land, the particle size and softness of the soil, and the surrounding water conservancy facilities, are the key to harvest.

Not to mention the processes of ploughing the land, transplanting seedlings, and planting seeds, if there is no first

Mechanized farming machines require a lot of manpower and time. In addition, weeds, pests and even simple birds and beasts are the enemies of farmers.

Jera's grandfather was also a farmer, and he lived in the countryside when his family was young, so he is well aware of the hardships of farmers.

However, if the hydroponic farm building of Xia Hui Ling is popular....

Then the time and place will be controlled by the people themselves!

Not to mention anything else, if the Flying Flame Land had another "biological warfare", then Nanling would not have been hit by everything like this at all!

At that time, if the inconsistencies of the Flying Flame Land wanted to spread the virus and fungus, they needed not to simply throw fungi bottles around, but to attack the bunkers one by one!

Of course, not all of them are advantages.

Even a layman like Jera can see many shortcomings in hydroponic buildings: it requires a considerable amount of energy to meet the needs of light, regulate temperature, and the complex process can only be mastered by a trained grower.

For those crops that are too cheap, the use of hydroponic buildings will increase the cost of cultivation and even the cost of education for farmers.

But how can this be said to be completely bad?

To completely strip agriculture from ordinary "hard work" and turn it into an industrial activity that requires skill and patience. This kind of technology will definitely not only be limited to Xia Hui Territory in the future, but the entire Nanling, the entire empire and even the entire Terra will be gradually changed!

Whether it's high-end sublimation plant cultivation or low-end vegetables, everything will usher in epoch-making changes!

"It's..."

He muttered to himself in his heart: "What a good opportunity for our engineering team to develop and grow!"

Noticing Jayla's reaction, Ian nodded.

Although Gera is an educated sublimator and not an ordinary person, his opinion can also represent the perception of the vast majority of people in Terra Gera and his engineering team are so optimistic about the hydroponic building, so what about those big merchant envoys who are about to come to the Xia Hui Territory, and even the guests from the imperial capital?

As long as they are optimistic, then wouldn't the investment come naturally?

With that in anticipation, Ian waited.

A few days later, Tymo, Viscount Decas, with representatives of the Chamber of Commerce from the City of Knowledge and the Seven Cities Alliance, came to the Xiahui Territory.

The Sattar Empire, the South Ridge, the hilly area of the Golden Plains, the gathering place of refugees in the west.

Bitter Cold Village.

The arrival of the new year does not bring any festive atmosphere to the place, only a more icy cold wind and gloom.

The natives of Nanling almost never go to the hilly land, where there is no suitable land for farming, and there are not many wild animals and herbs, and although there are some fish and shrimp in the rivers and streams, and there are shallow lakes as water sources, it is very difficult to feed people.

But the hard and the impossible are not the same. For many years, the hilly terrain has been a gathering place for those who cannot survive in the South Ridge: those who are in debt, those who commit crimes, those who have fled, those who have been persecuted and left, and those who want to hide for a while..... Poor people of all kinds of hardships have built several villages here.

But no one can live here for long. People in the village come and go, life and death, and every few years they will change or die, just like the weeds on the side of the road, no one cares.

Miles didn't quite understand why the locals had given their village the unlucky name "Bitter Cold," but now he did.

Because it's really cold.

The slippery cold of Nanling is certainly not as cold as the cold that can directly freeze people to death in the north, but people who are frozen to death by the cold cannot live to express their feelings - only the living will suffer, not to mention that there is a small river and shallow lake next to the bitter cold village, which is the source of food in summer and the source of eerie humidity in winter.

Miles has never experienced such a cold winter, although the apartment in the Azure City is old, but it has all the facilities it should have, the walls have not cut corners, the warmth is very good, even if life is a little embarrassing, but the mother will be careful to save enough for the winter when the carbon fire is cheap.

Since the events of Avak and the turmoil in the West, a large number of refugees from the West and the inhabitants of the Grand Dukes of Thorin have been moving to the north and south, and most of the wealthy have chosen to go to the Central, and those who know that they are going to the Central

Those who have no way to survive and can only be refugees choose to go to Nanling, because there is at least relatively "free" land here that can accommodate these desperate people who have fled their homes in a hurry.

Miles had originally planned to travel to the Midlands - on the day he left Avak, he was helped by an unknown nobleman and had a box of survival supplies to start with.

With such a box of supplies, selling some of the medicines and tools in it is enough to temporarily live in a small town in the central region, and then find a job to support Cynthia and herself.

If everything goes well, it will be so, but the world is impermanent.

In order to prevent conspiracy, the central region has now adopted a very strict entry and exit verification system, not to mention refugees like them, even caravans with backgrounds have to issue a lot of certificates if they want to go back and forth, and those officials and clerks guarding the checkpoint will not care if you are miserable.... They only care about whether they have a certificate or not, whether they will be blamed from above.

Avak led everyone from top to bottom to be wiped out, where did the people come from to issue certificates to the brother and sister?

Unable to go to the central area, they could only go south, and after more than a month of bumpy rides, they could be regarded as arriving at Nanling safely.

Then there was a food disaster and a civil war among the mountain people.

Although Southridge's intermittent vetting is not as strict as that in the central region, with the status of refugees in sensitive areas like Miles and Cynthia, it is still difficult to enter major cities to live and find a job, not to mention that Miles actually has no serious survival skills, he can use swordsmanship, and a little ...... Awakened psionic powers.

However, this psionic ability, Miles himself can't use it very well, and it can only work when Cynthia is by his side and is in danger.

Usually use it yourself, you can strengthen your body and resist a little cold, but other than that, it's not much use.

As a last resort, they had no choice but to come to this hilly homeless village called "Bitter Cold" and silently insist on waiting until the situation calmed down.

Now, the situation is indeed much calmer, and with the full retreat of the Spike spies, these refugees have also been relaxed and can enter and leave the town.

But there is really no work in the winter, and there is no way to stay in the city without making money.

They still have to wait...... Wait for spring to come.
