Chapter 351 New Agriculture

Why can these salt pools be heated without fire?

This question lingered in the minds of all visitors.

Chi was the same - she wanted to know the answer very much, but her pride prevented her from speaking. There is no doubt that this should be the core secret of Jinxia City, and her inquiry was bound to be perfunctory and rejected. As the owner of Penglai Island, she could not let everyone lose face.

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

Chi nodded subconsciously.

The moment her head moved, she regretted it.

How could the other party tell her the trump card of Yancheng?

This move was equivalent to admitting that she knew nothing about this, and it would be difficult to take the initiative in front of this person.

"Because of the shock technique." Xia Fan did not show any irony, but explained seriously, "Electricity is a widely used secondary energy source that can be easily converted into heat energy. I wonder if you have ever thought about why there is a huge sound when lightning strikes?"

Secondary...what? Chi blinked and unconsciously added, "...I haven't thought about it."

"That's because lightning heats the air, causing it to expand rapidly and make a popping 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, "Look."

As his voice fell, the thin copper wire slowly floated up in full view of everyone.

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

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

Kong Xuanzi and others exclaimed.

The effect of driving the shock technique without using medicine is so obvious. Has the art of the Privy Council 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 then the copper wires are heated by the streamer technique, and then the water boils?"

"That's roughly right, but the copper wires 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 exploring." Xia Fan praised, "But you can quickly think of this, which is faster than many people."

Chi just smiled, and then quickly covered the corner of her mouth, "You told me this, aren't you afraid that I will secretly spread it? For Yancheng, this should be a great secret, right?"

"It's not a secret. These contents are all within the scope of the school."

"School... refers to private schools?"

Xia Fan replied considerately, "You can understand it this way, but Jinxia School recruits children of the right age in the city. Anyone who is willing can apply to participate."

Chi was stunned.

The principle of this salt boiling method can actually be learned by everyone in the city?

"Won't it be easily leaked!" She couldn't understand for a moment, what good would this do to Jinxia City? There are many in the coastal city continent. If they master this technology, the strength of the Privy Council will surely be further enhanced.

Xia Fan had a strange feeling in his heart.

It was as if the girl Chi in front of him was not just a passer-by in Penglai, but one of the investors in Jinxia City, who was supervising and reviewing his policies. "Don't worry, it's not a matter of one or two words to transform theory into actual production, but this knowledge can arouse students' interest in exploring the truth. I don't think it's a losing business. Aren't you one of the beneficiaries?"

"Uh..." Chi was speechless.

"Let's go, it's time to visit the farmland next." Xia Fan said.

...

The farmland of Jinxia City is only half a mile away from the salt field. It was originally just a barrier to prevent the alkalization of the land. If the east city wall and the salt field are regarded as two parallel lines, the farmland is the "green belt" separated in the middle.

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

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 set up farmland by the sea, but the people of Penglai were surprised to find that under these snow-covered lands, there were actually clusters of green seedlings.

In other words, the farmers in Jinxia not only planted winter wheat in the sand, but also the wheat grew quite vigorously.

However, 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 reclaimed make the people of Penglai seem to have come to a completely different era-

More than a dozen giant beasts were seen moving slowly in the sand and gravel, dragging shiny metal plows behind them, and the width alone was as much as six feet! The land that had not been turned over for thousands of years was as soft as batter in front of the metal plow blades. A large amount of mud and sand that was pushed out formed a series of towering "low walls" next to the giant beast's feet.

Anyone who saw the special plow harrow could intuitively feel its weight and rigidity - the exaggerated size of the body and the size of the plow blade were definitely not designed for oxen or manpower. 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 giants could pull them.

Every time it took a step, its wide feet would sink into the mud and sand for an inch. Even so, its body was still as stable as a rock, and it did not look powerless at all.

"Is that... a mechanical creation?" Kong Xuanzi murmured. Penglai Island also recorded the ingenuity of mechanical arts, but the real objects were mainly hidden weapons and crossbows, and the largest ones were dummy puppets. Compared with the giant beast in front of him, those things were as slender and fragile as embroidery needles.

Chi Ze noticed the operators of the mechanical beasts.

Some of them were obviously not human.

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

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

"Lord Xia, good afternoon." A plump blue-haired woman noticed the appearance of a group of people and walked towards this side with an elegant step - she was Elder Shuzhou, High Priestess Senia. "Are you here to review the training results of the new batch of soldiers?"

"Good afternoon, Ms. Senya." Xia Fan replied with a smile, "I'm just taking people for a casual tour. By the way, it's pretty good to use this method to train the balance of the operator."

"That's right." The high priest smiled with his hands covering his mouth, "At least they can find a stable job after leaving the army. But I think that reclaiming wasteland is your first goal."

It was Xia Fan's idea to use the black tortoise mechanical beast to replace the oxen. If we talk about modern agriculture, it is nothing more than fertilizer, water conservancy construction and mechanized farming. Needless to say, the first two, root nodule grass 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 not much worse than nitrogen fertilizer or tap water irrigation system.

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