Heavenly Dao Formula

Why are these salt pools heated without fire?

This question is entrenched in the minds of all visitors.

The same is true for Chi - she really wants to know the answer, but her self-esteem prevents her from speaking. There is no doubt that this should be the core secret of Jinxia City, and her inquiry is bound to attract perfunctory and rejection. As the owner of Penglai Island, she cannot let everyone lose face.

But unexpectedly, Xia Fan took the initiative to talk to her and said, "Are you curious, why can you boil water and boil salt without seeing any firewood here?"

Chi nodded subconsciously.

The moment her head shook, she regretted it.

How could the other party tell her Yancheng's trump card?

This move is tantamount to admitting her ignorance in this regard, and it will be difficult to take the initiative in front of this person.

"Because of the shock technique." Xia Fan did not show the slightest irony, but explained seriously, "Electricity is a secondary energy source with a wide range of uses, which can be easily converted into heat energy. I don't know if you have ever thought about why When the lightning strikes, there will be a huge sound?"

Level two... what? Chi blinked, then subconsciously added, "...I haven't thought about it."

"That's because the lightning heats the air, causing the latter to expand rapidly and make a crackling sound. It can heat the air, so it can naturally 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 up under the eyes of everyone.

Then several tiny blue lights jumped out from his palm and penetrated into the copper wire.

After a while, the copper wire showed a scorching bright red, as if it was already extremely hot.

Kong Xuanzi and the others let out a burst of exclamation.

The effect of driving the shock technique without using medicine is still so obvious, has the Privy Council's alchemy progressed to this point?

Chi didn't care about this, her eyes lit up and she said, "You mean, there are copper wires embedded in the bottom of these pools, and the streamer technique is used to heat the copper wires, and then make the water boil?"

"It's roughly correct, but the copper wire can't be in direct contact with the salt water, and the heat transfer can't rely on the pool itself. There are still many details worth studying." Xia Fan praised, "But you can quickly think of this point, It has reacted faster than many people."

Chi just smiled, and quickly covered the corners of his mouth, "If you tell me this, you won't be afraid of being sneaked out by me? For Yancheng, this should be a great secret, right?"

"There is no secret, these contents are all within the teaching scope of the school."

"School...does it mean private school?"

Xia Fan replied thoughtfully, "You can understand it this way, but Jinxia Academy's enrollment targets are all school-age children in the city. Anyone who is willing can apply to participate."

Chi was stunned.

The principle of the method of boiling salt can be learned by the whole city?

"Isn't that easy to leak out!" She couldn't understand for a while, what good would Jinxia City do by doing so? There are quite a few cities on the mainland by the sea. If they master this technology, the strength of the Privy Council will definitely be further improved.

A strange feeling rose in Xia Fan's heart.

It was as if the lady in front of her was not just a visitor from Penglai, but one of the investors of Jinxia City, who was monitoring and reviewing his policies. "Don't worry, the transformation of theory into actual production is not something that can be solved in one or two sentences, but this kind of knowledge can arouse students' interest in exploring the truth. I don't think it is a loss-making business. Aren't you also a beneficiary of it? one of them?"

"Uh..." Chi was speechless for a moment.

"Let's go, it's time to visit the farmland," 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 land from being alkalized. If the east city wall and the salt field are regarded as two parallel lines, the farmland is the "green belt" in the middle.

Due to the unexpectedly good soil-fixing and fertilizing effects of the phylloxera provided by the elves, the experimental field project has now entered the formal production stage. The newly reclaimed land extends south along the coastline, and the planned area almost reaches the mountains in the east of Gaoshan County under.

According to common sense in the past, these lands with extremely high sand content have no value for cultivation at all, and no one would choose to locate farmland by the sea, but the people of Penglai were surprised to find that under these snow-covered lands, there are actually many Clusters of green seedlings.

In other words, the Jinxia farmer not only planted winter wheat in the sand, but the wheat was also growing vigorously.

But what really stunned them was not the scene in the farmland.

Compared with the fields that have been cultivated, those new areas that are being cultivated make everyone in Penglai seem to have come to a completely different era——

I saw more than a dozen giant beasts moving slowly in the gravel, with shiny metal rakes dragging behind them, the width alone was as much as six feet! The land that had not been turned for thousands of years was as soft as batter in front of the metal coulters, and a large amount of sand that had been pushed out formed a series of towering "low walls" beside the giant beast's feet.

Anyone who sees a special plow rake can intuitively feel its weight and stiffness—the exaggerated body size, as well as the size of a coulter, are by no means designed for cattle or manpower. Even if five or six adults lift it up, they may not be able to lift it out of the sand.

Only those giant bipeds can pull them.

Every time it took a step, its wide feet would sink into the mud and sand. Even so, its body was still as stable as a rock, and it didn't look weak at all.

"Is that... a creation of mechanism?" Kong Xuanzi murmured. Penglai Island has also recorded the ingenuity of mechanism technique, but the real objects are mainly hidden weapons and bows, and the biggest ones are dummy puppets. Compared with the giant beast in front of them, those things are as thin and fragile as embroidery needles.

Chi noticed the controller on the mechanism beast.

Some of them are clearly not human.

Flaxen or chestnut hair, long pointed ears, and mostly light gray pupils... She realized that they were not only demons, but also overseas demons.

No wonder the residents of the city accepted her so highly. It turned out that the cooperation between demons and humans had already progressed to a very deep level in Jinxia City.

"Master Xia, good afternoon." A plump blue-haired woman noticed the appearance of a group of people and walked towards this side with graceful steps—she was the elder Shuzhou, the high priest of Xenia. "Are you here to review the training results of the new batch of fighters?"

"Good afternoon, Ms. Senia." Xia Fan replied with a smile, "I just showed people around for a while. Having said that, it is quite good to exercise the balance of the manipulator in this way."

"That's true." The high priest covered his mouth with a smile. "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 Mechanism Beast to replace the cattle. If you want to talk about modern agriculture, it is nothing more than chemical fertilizers, water conservancy construction and mechanized farming. Needless to say, the first two, phylloxera and soft bamboo are 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.

And the last important task of mechanization naturally fell on the mechanism beast.
