Heavenly Dao Formula

When seeing the princess's people, Xia Fan felt that these people were not ordinary at first sight.

They were able to stand in a row while waiting, instead of scattered in a few piles. Although they are tall and short, they are basically strong, with obvious muscle outlines in their arms - in the era of underdeveloped agriculture, muscles were a luxury.

From the perspective of physical standards, these people undoubtedly exceeded Xia Fan's expectations.

"They were soldiers?"

"You have a good eye." Ning Wanjun smiled, "Didn't you ask me to call people over last time? They just want to. Although these people are best at rushing to kill people, when there is no war, they will also Wielding a hoe. Centralized management and secrets must be kept. After much deliberation, using them is the most reassuring for me."

Sure enough, the third princess' hole card was the army she had been in, Xia Fan thought, she could not control the Qiguo frontier army on the surface, but secretly she could use it to cultivate her own power.

"How many people can you muster?"

Probably because this question is too sensitive, Ning Wanjun squinted and stared at him for a while, and when Xia Fan thought that the other party would not reveal it, she breathed out slightly, "Three or four thousand should be fine. But I can't take them Take it all to produce salt, long hours of labor will reduce your combat capability, and giving you 100 people is the upper limit."

"I think so too." Xia Fan not only didn't mind, but agreed with it very much.

Salt is the core of Jinxia's development, but force is the basis for ensuring development.

The other party's ability to answer this question has already proved her trust and determination.

With this support, Xia Fan also felt a lot more relaxed.

"Then without further ado, let's start now."

...

Regarding the idea of ​​the salt farm, Xia Fan had already prepared a draft in his heart.

He not only inspected the coast several times, but also asked local fishermen about the sea conditions, tidal patterns, and the weather in recent years. He concluded that the shallows outside Jinxia City are a good place for drying salt. Every year from May to late October, the sunshine and rainfall are very steady.

This is also due to the flat terrain in this area, the sea breeze can blow directly into the inland, and the temperature changes can be traced. A little further south, the situation is quite different. For example, Gaoshan County is blocked by a mountain range, and the hot and cold air changes frequently, which not only brings rainfall more easily, but also rains more suddenly.

Wang's salt field is also on the beach, but because it relies on firewood and other fuels, its location is closer to the river wharf. And this wide beachhead is about 30 to 40 kilometers long, so he can choose a sparsely populated area.

"Choose the test site here."

After leading the team to walk for about half an hour, Xia Fan stopped in front of a natural sandy slope.

"I don't know how to do it, you have the final say on this matter." Ning Wanjun signaled his subordinates to gather around, "If you have any request, tell them, and they will carry it out."

Although he had never seen this person before, the princess' words were like a military order, and everyone's eyes turned to Xia Fan.

Xia Fan pondered for a while, and said loudly, "Everyone, we are going to open a saltworks here."

"I heard that you all worked as farmers when you were in the army, and what you have to do here is no different from plowing and reclaiming wasteland. First, we have to create several flat lands on the hillside. Each flat land does not need to be too large. But there must be bricks and stones around it, which can be used to hold water. Secondly, there should be a drop between the flat ground, and it should not exceed half an arm, which looks the same as the terraced fields in the south..."

He slowed down his speech and tried to explain the task in the simplest terms, so that everyone could understand what he was going to do next.

The principle of drying salt is not complicated, but there are still many details worth studying. If it is not well grasped, the efficiency will be greatly reduced, and it will even be difficult to produce salt. Because of this, sea salt will be mainly boiled for a long time.

Although Xia Fan has never been to a salt field, he has seen many related pictures - due to the improvement of productivity, many small salt fields have gradually changed from production bases to local landscapes, where the white salt field and the blue sea water meet on the horizon , can always make people feel that human beings have transformed nature.

What he has to do now is to reverse its production process based on known principles and impressions in memory.

The most important point of the salt farm is to separate the different concentrations of saline seawater, so as to increase the production speed of each round and reduce the demand for manpower.

When the sea is at high tide, the saltworks have to open the gates to receive water, introduce natural raw materials into the storage canal, and use water trucks, manpower, etc. to pour the seawater into the topmost pool. Wait until the water evaporates to a certain extent, then let the seawater flow into the pool below, and then repeat the process.

As the steps decrease, the brine concentration in the pool will become higher and higher until coarse salt is precipitated. The upper pool can be injected with new sea water immediately after the water is released until a cycle is formed.

It is now the first ten days of September, and he hopes to complete the verification test by October and start production before the end of autumn. Even in winter, Jinxia City will not become icy and snowy, and the reduced efficiency can be fully compensated by expanding the scale.

In addition, there is no essential conflict between the sun-dried salt method and the boiled salt method, and high-concentration salt water will only be more convenient when boiling. He even plans to erect a salt cooking plant near the salt pond to achieve round-the-clock production.

Of course, Xia Fan didn't pay attention to the Wang family's production experience at all. It would be embarrassing to talk about such backward craftsmanship as burning wood and boiling water. In addition to using solar energy, there is also a more intuitive energy source that can be used-that is alchemy.

This is also the inspiration brought to him by the previous electromagnetic gun research.

As long as a short circuit is formed, the current can heat the conductor to a very high temperature in a very short time. If copper strips are laid under the salt boiling pool, and then shocks are applied to it, wouldn't it be an ancient electric water heater?

At that time, let alone boiling salt, it will be easy to boil a pool of water dry.

The only problem is that he needs to recruit a few hardworking alchemists.

Xia Fan does not intend to act as this "heating source" by himself.

I don't know if those candidates who received his invitation letter will come to Jinxia City... He couldn't help thinking.

...

"Bang!"

With a crack, the car body shook suddenly, and stopped moving forward abruptly.

"Unlucky!" The coachman cursed, and then opened the curtains with an apologetic face, "My lord, I'm sorry, I just didn't notice a pothole on the road, which broke the axle. Or... I will refund the money Here you go, would you like another carriage?"

Sitting in the carriage was Mo Yun who came from Gyeonggi.

Accompanying him were two servants of his own family.

She originally wanted to return to Jinxia with the princess' guards, but there was still a secret letter on the other party's body that needed to be delivered as soon as possible, so the two had to start the journey separately. She is not good at riding a horse, and the distance is far away, so she chose to hire a car, but she did not expect to encounter such an accident halfway.

Mo Yun frowned, and stepped out of the rickety carriage - just as the coachman said, one wheel of the carriage was skewed, and it was obvious that it could no longer run.

This is the official road leading to Shenzhou. People will pass by from time to time, and there is no safety problem. It's just that the passing vehicles often carry people and goods. It is not necessary to meet a carriage that can take them down. so easy.

"How far is this place from Jinxia?" She asked in a low voice.

"I guess it's about two days' journey."

It's really not a good sign for her to have such a problem halfway through the itinerary... Mo Yun thought.
