Heavenly Dao Formula

　　 When meeting the princess's people, Xia Fan felt that these people were unusual at first glance.

　　 They can actually stand in a row while waiting, instead of sparsely gathering in several piles. Although they are tall or short, they are basically strong, and the arms can see obvious muscle contours-in the era of underdeveloped agriculture, muscles are a luxury thing.

　　 Judging from physical standards, these people undoubtedly exceeded Xia Fan's expectations.

　　 "They were soldiers?"

"You have a good vision." Ning Wanjun smiled, "Didn't you ask me to summon people over last time? They are. Although these people are best at rushing to kill, but when there is no war, they will also Wielding a hoe. I have to focus on management and keep secrets. I think about it or use them to make me feel at ease."

　　 As expected, the three princesses' trump card was the army she had been in. Xia Fan thought to herself that she could not control the Qiguo border army on the face of it, but secretly she could use it to cultivate her own power.

　　 "How many people can you gather?"

Probably because this question is too sensitive, Ning Wanjun squinted at him for a long time. Just when Xia Fan thought the other party would not disclose, she exhaled slightly, "Three or four thousand should be fine. But I can't take them. All of them are used to produce salt. Long-term work will reduce the combat ability. If you give you 100 people, it will be the upper limit."

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

　　Salt is the core of Jinxia's development, but force is the foundation to ensure development.

　　 The other party can answer this question, it has proved her trust and determination.

　　With this support, Xia Fan also feels a lot relaxed.

　　 "Then it should not be too late, let's start now."

　　……

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

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

　　 This is also due to the flat terrain in this area, the sea wind can blow directly into the inland, and the temperature changes can be traced. If it goes a little further south, the situation is quite different. For example, Gaoshan County is blocked by a mountain range. The hot and cold air changes frequently, which not only makes it easier to bring rain, but also rains more suddenly.

　　The salt field of Wang’s family is also on the beach side, but due to its reliance on firewood and other fuels, its location is closer to the inland wharf side. And this broad beach is about 30 to 40 kilometers long, and he can pick out a sparsely populated area.

　　 "Choose the test site right here."

　　 led the team to walk for almost half an hour, and Xia Fan stopped in front of a natural sand slope.

　　 "I don't understand how to do it, you have the final say." Ning Wanjun motioned to his subordinates to gather around, "If you have any requirements, tell them and they will execute them."

　　Although she had never seen this person before, the princess' words were like military orders, and everyone looked at Xia Fan.

　　 Xia Fan brewed, and said loudly, "Everyone, we are going to open a salt field here."

"I heard that you all worked in farming when you were in the army, and what you have to do here is no different from ploughing and reclaiming wasteland. First of all, we have to set up a few flat areas on the hillside. Each flat area does not need to be too large. But the surrounding area must be sealed with masonry, which can be used to hold water. Secondly, there should be a drop between the flat ground and no more than half an arm. It looks like the terraced fields in the south..."

　　 He slowed down and tried to explain the task in the simplest terms, so that everyone could know 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 mastered, the efficiency will only be greatly reduced, and it may even be difficult to produce salt. Because of this, sea salt will be mainly boiled for a long time.

Although Xia Fan has not been to the salt field, he has seen a lot of related pictures. Because of the improvement of productivity, many small salt fields have gradually changed from production bases to local landscapes. The white salt fields and the blue sea are connected to the horizon. , Can always make people feel that human beings transform nature.

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

　　The most important point of the salt field is to separate different concentrations of salty seawater in order to increase the production speed of each round and reduce manpower requirements.

　　 When the sea is high tide, the salt field must open the gate to receive water, introduce natural raw materials into the water storage canal, and use waterwheels, manpower, etc. to pour the seawater into the topmost pool. Wait until the water evaporates to a certain level, and then let the sea water flow into the pool below, and then repeat the process.

　　As the steps decrease, the concentration of brine in the pond will become higher and higher until coarse salt is precipitated. The upper pool can be filled with new sea water immediately after the water is discharged, until a circulation is formed.

　　 It is early September, and he hopes to complete the verification test before 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 boiling salt method. High-concentration salt water will only be more convenient when boiling. He even plans to set up a salt cooking plant near the salt pond to achieve all-weather production.

　　 Of course, Xia Fan didn't take the Wang family's production experience into consideration at all. It would be embarrassing to talk about the backward technology of 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 for him from 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 period of time. If copper strips are laid under the salt boiling pond and then subjected to vibration, wouldn't it be an ancient electric water heater?

　　 Don't even talk about boiling the salt at the time. It is probably easy to boil a pool of water~www.ltnovel.com~ The only problem is that he needs to recruit a few alchemists who work hard.

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

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

　　……

　　 "Dang!"

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

"Unlucky!" The coachman cursed, and then opened the curtains apologetically, "Sir, I just didn't notice a dirt hole on the road and broke the axle. Or... I refunded the money. Here you are, do you change another carriage?"

　　 In the carriage, it was Moyun from Gyeonggi.

　　 accompanied by two of his own attendants.

　　 She wanted to return to Jinxia with the princess' guards, but there was still a secret letter on the other side that needed to be delivered as soon as possible, so the two only scored to start the journey. She is not good at horseback riding, and because of the long distance, she chose to hire a car. She unexpectedly encountered this kind of accident when she was halfway down the road.

　　 Mo Yun frowned, and walked out of the rickety carriage-just as the coachman said, one of the wheels of the carriage had been skewed, and it was obviously impossible to run.

This is the official road leading to Shenzhou. People will pass by from time to time. There is no safety problem. It’s just that passing vehicles often carry people and goods. If you want to meet a carriage that can take them off, there is no so easy.

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

　　 "I guess it's almost two days away."

　　 This kind of problem occurred halfway through the trip, which is really not a good sign for her... Mo Yun said in his heart.
