Why can these salt pools be heated without fire
This question lingers in the minds of all visitors.
The same is true for Chi - she really wants to know the answer, but her pride prevents her from speaking. There is no doubt that this should be the core secret of Jinxia City, and her inquiry is destined to be perfunctory and rejected. As the owner of Penglai Island, she cannot let everyone lose face.
But what she didn't expect was that Xia Fan took the initiative to talk to her, "Are you curious why there is no firewood here and it can boil water and boil salt?"
Chi nodded subconsciously.
The moment her head bobbed, she regretted it.
How could the other party tell her Yancheng's trump card
This move is tantamount to admitting that she knows nothing about this, and it will be difficult for her to take the initiative in front of this person.
"Because of the shock technique." Xia Fan did not reveal any sarcasm, but explained seriously, "Current is a very versatile secondary energy source that can be easily converted into heat energy. I don't know if you have ever thought about why. When lightning strikes, will there be a huge noise?"
Level 2... what? Chi blinked and unconsciously added, "...I never thought about it."
"That's because lightning heats the air, causing the latter to expand rapidly and make a popping sound. It can heat the air, and naturally it can also be used to heat other things." Xia Fan took out a copper wire pendant and peeled off the thin copper wire on it Come down, "Look."
As his words fell, the thin copper wire slowly floated in front of everyone.
Then several small rays of blue light jumped out from his palm and penetrated into the copper wire.
After a while, the copper wire turned a scorching bright red color, as if it was extremely hot.
Kong Xuanzi and others let out a burst of exclamation.
The effect of using seismic techniques without the use of medicine is still so obvious. Has the Privy Council's alchemy advanced to this point
Chi didn't pay attention to this. Her eyes lit up and she said, "You mean, these pools are embedded with copper wires at the bottom, and then the streamer technique is used to heat the copper wires, and then make the water boil?"
"It's roughly true, but the copper wire cannot be in direct contact with the salt water, and the heat transfer cannot be done by the pool itself. There are still many details worth studying." Xia Fan praised, "But you can quickly think of this, Already reacted faster than many people.”
Chi just smiled and quickly covered the corner of his mouth, "Aren't you afraid that if you tell me this, I will secretly spread it out? For Yancheng, this should be a big secret, right?"
"Secrets are out of the question. These contents are within the scope of teaching in the school."
"School... does it mean private school?"
Xia Fan thoughtfully replied, "You can understand that, but Jinxia Academy recruits all school-age children in the city. Anyone who is willing can apply to participate."
Chi was stunned.
The principle of boiling salt can be learned by everyone in the city
"Wouldn't that be easily leaked?" She couldn't understand for a moment. What benefits would this do to Jinxia City? There are many cities on the mainland by the sea. If they master this technology, it will definitely further enhance the strength of the Privy Council.
A strange feeling arose in Xia Fan's heart.
It was as if the hot girl in front of him was not just a passer-by in Penglai, but one of the investors of Jinxia City, who was supervising and reviewing his policies. "Don't worry, the transformation of theory into practical production is not something that can be solved in one or two sentences, but this knowledge can arouse students' interest in exploring true knowledge. I don't think it is a loss-making business. Aren't you also a beneficiary? One of them?"
"Uh..." Chi was speechless for a moment.
"Let's go, it's time to visit the farmland next," Xia Fan said.
…
The farmland in Jinxia City is only half a mile away from the salt field. It was originally just a barrier to prevent the alkalinization of the land. If the east city wall and the salt field are regarded as two parallel lines, the farmland is a "green belt" separated in the center.
Due to the unexpectedly good soil-fixing and fertilizing effects of rhizobia provided by Elf, the experimental field project has now entered the formal production stage. The newly reclaimed land extends southward along the coastline, and the planned area almost reaches the mountains east of Gaoshan County. under.
According to common sense in the past, these lands with extremely high sand content have no value for farming at all. No one would choose to locate their farmland near the sea. However, the Penglai people were surprised to find that under these snow-covered lands, there were actually many There are clusters of green seedlings.
In other words, Jinxia farmers not only planted winter wheat in the sandy land, but the wheat also grew vigorously.
But what really stunned them was not the scene in the farmland.
Compared with the fields that have been cultivated, the new areas that are being cultivated make everyone in Penglai feel like they have entered a completely different era -
I saw more than a dozen giant beasts advancing slowly in the gravel ground, dragging shiny metal rakes behind them, which were as wide as six feet! The earth that had not been turned over for thousands of years was as soft as batter in front of the metal plow, and a large amount of pushed out sand formed towering "low walls" around the feet of the giant beast.
Anyone who sees a special plow can intuitively feel its weight and stiffness—the exaggerated overall dimensions and the size of a plow are definitely not designed for cattle or human labor. Even if five or six adults went up to lift it, they might not be able to lift it out of the sand.
Only those two-legged giant beasts can pull them.
Every time it takes a step, its wide feet will sink into the mud and sand. Even so, its body is still as stable as a rock, and it does not seem to be unable to do so at all.
"Is that... a machine creation?" Kong Xuanzi murmured. Penglai Island also recorded the ingenuity of the machine technique, but the real objects were basically hidden weapons and bows and crossbows, and the biggest ones were dummies and puppets. Compared with the giant beast in front of him, those things were as delicate and fragile as embroidery needles.
Chi Ze noticed the controller on the machine beast.
Some of them are clearly not human.
With flaxen or chestnut hair, long pointed ears, and mostly light gray eyes... She realized that they were not only demons, but also overseas demons.
No wonder the residents of the city are so accepting of her. It turns out that the cooperation between demons and humans has reached a very deep level in Jinxia City.
"Master Xia, good afternoon." A plump blue-haired woman noticed the group of people appeared and walked towards them with graceful steps - she was the elder Shuzhou and the high priest of Senia. "Are you here to review the training results of the new batch of soldiers?"
"Good afternoon, Ms. Senia." Xia Fan replied with a smile, "I'm just giving someone a casual tour. Having said that, it's quite good to exercise the operator's balance in this way."
"That's true." The high priest covered his mouth and smiled, "At least they can find a stable job after leaving the army. But I think that opening up wasteland is your first goal."
It was Xia Fan's idea to use Xuanwu machine beasts to replace farm cattle. To talk about modern agriculture, it is nothing more than chemical fertilizers, water conservancy construction and mechanized farming. Needless to say the first two, rhizobia and phoebe were the first tree spirit plants ordered from the elves. One can make the land fertile and full, and the other can automatically absorb rain and dew and allocate water supply. The effect is no worse than nitrogen fertilizer or tap water irrigation system. How much.
The last important task of mechanization naturally falls on the machine beast.
