Heaven's Formula

The three of them stood there blankly, with only one thought left in their minds, what happened just now?

The explosion just now sounded earth-shattering, but not many things were destroyed at the scene, even the weird shelf around Xia Fan seemed intact.

Except for that courtyard wall.

Ning Wanjun took a deep breath and strode towards the entrance of the cave.

"Your Highness, please be careful!" Qiuyue chased after her, blocking herself behind the princess, her eyes fixed on the still smoking copper frame.

Ning Wanjun walked to the wall, bent down to observe for a while, and confirmed his opinion - something penetrated the wall at a very high speed and disappeared outside the villa.The size of the hole is regular, and there are obvious cracks around it, which doesn't seem to be caused by a magic spell. She reached out to explore and found that there was still residual heat inside.

Although this wall is made of red bricks, it is not as hard as a stone wall, but its thickness is about ten fingers. The shock technique!

Although the thunder is strong, it is difficult to destroy the entity, which is also the commonality of the shock technique.

Has Xia Fan's research reached this point?

"Your Highness, are you alright?"

"The subordinate just heard a strange noise coming from the courtyard, and came here to escort him!"

Guards had already approached the gate of the other courtyard, obviously the huge roar just now had aroused their vigilance.

"There's nothing going on here, you stay outside the courtyard and don't let idlers approach!" Ning Wanjun said decisively.

"As ordered!"

Then she looked at Xia Fan impatiently, "Can you explain this technique to me?"

"It's just an ordinary streamer technique." The latter spread his hands.

"Shock technique streamer? Isn't that triggering lightning in the palm?"

"Indeed, but when the current is large enough, it can trigger some magical phenomena, such as the generation of strong electromagnetic force-of course, this does not mean that it does not exist when it is small, but it is difficult to attract people's attention."

Ning Wanjun was silent for a while, "...can you speak more simply and understandably?"

Xia Fan was also stuck - after all, he was speaking in the simplest terms. "You can understand that electricity and force can be transformed into each other under certain conditions. The streamer technique seems to just trigger lightning, but through this guide rail, it can be turned into a huge thrust."

This is also the principle of the rail gun.

In fact, Xia Fan himself did not expect the first test to be so smooth - after all, the equipment is really simple and the purity of the copper rods is also worrying. Even the magnets laid under the track are used to guide the electric field and provide additional magnetic force He spent half a day picking all the stones from the blacksmith shop.At the beginning, it was expected that as long as the projectile was pushed against the wall, it would be considered a successful attempt, but it turned out that the copper cone acting as the shell not only hit the wall, but also shot directly through it.

This is really incredible.

When Xia Fan cast the streamer technique, he already realized that the technique had undergone subtle changes.

For example, the condensed qi at this time is no longer lively and rough, but thick and stable, like a rolling torrent.

"The most important thing in alchemy is thinking about it."

"Even if it is a spell of the same attribute as myself, different people will have great differences in casting it - it depends on proficiency, understanding ability and personal perception."

The shock technique streamer may have engraved a unique "mark" on his hands.

Ning Wanjun had another thought in his mind.

If this thing can be put on the battlefield, it will definitely be a great weapon in the army!

Compared with iron cannons, a few copper frames are much lighter.And this thing does not need flammable materials such as saltpeter and carbon powder from the beginning to the end, and it will not kill itself in turn.

But none of the above is critical.

The key is that it is too fast, so fast that people are caught off guard!

She asked herself that she could avoid bows and crossbows when she was at full strength, but she definitely couldn't dodge this thing—even capturing its firing line with the naked eye was a difficult thing to do.

When the two armies confront each other, the general will often stand at the front of the team in order to observe the situation and take the lead in the charge.What would happen if the shock technique was used suddenly at this time?

She could see the next scene almost without thinking: the general died before the battle, the enemy retreated timidly, and her own side took advantage of the situation to cover up the kill, how can it be invincible?

"Can I use this technique?" Ning Wanjun's tone became hot.

"Your Highness, your heart is separated..." Qiuyue reminded in a low voice, it was the first time she saw the princess so excited.

Even when she led the army for the first time and won a big victory, she had never been so excited.

It's like a child seeing his favorite toy.

"There is no separation between Li and Zhen. Those who belong to Zhen often turn to practice Li. I don't think this is a problem."

"But you don't even know how many Lijutsu."

"..." The princess was dumb for a moment, her expression was solemn, as if she was engaged in a huge inner struggle, and she patted Xia Fan's shoulder after a long time, "I will start learning the shock technique from today, if there is something I don't understand, I hope you A lot of pointers."

Li Ze put his hand on the other shoulder, and the twinkle in his eyes showed his thoughts fully.

She also wants to learn.

The problem is... the fox demon belongs to Kan, right?Xia Fan slandered in his heart, you are not only in the second position, but also in the opposite position.

But he found that he couldn't refuse the fox demon wagging its tail.

"Okay, I'll teach you some time in the future." Xia Fan said helplessly, "However, this technique is immature, and there are still many problems to be improved."

"Immature?" Ning Wanjun asked in surprise, this is called immaturity, so what will it look like when it is mature?We must know that when the Ministry of Industry meets the requirements of the army, it will make do with less and not give more. "You can't expect it to be as convenient as ordinary alchemy, right?"

"Compared to a certain junior high school student, it's really far behind." Xia Fan sighed—the railgun's routine problems, this test prototype almost didn't miss any.For example, the cannonball and the rail cannot fit tightly, causing the arc to strike, and the high temperature generated by the arc will ablate the rail; another example is that the energy required for its launch is so great that he feels that the energy in his body is exhausted just once. Seven or eight.

Of course, the most terrible thing is that the discharge end must be grounded. If he only relies on his body to complete the current circulation and uses his arms as guide rails, then when the improved streamer technique pours into his body, he will instantly become a coke.

This means that as long as Xia Fan wants to use this trick as a trump card in the future, he has to carry a heavy metal frame on his back and ensure that it is well grounded, otherwise it will be tantamount to suicide.

In this way, no matter how strong this technique is, it will not be forceful at all. This is the most distressing thing for him.

People... are still restricted by this body.

The more he studies alchemy, the more Xia Fan feels this way.

It's a pity that no one can understand this regret except himself.

"By the way, why did your Highness come to find me?"

Xia Fan didn't feel that the other party was idle and happened to wander over to him.

Ning Wanjun nodded, "I just want to tell you that I have already recruited all the people you need to make salt."

Chapter 1 and Three "Salt Fields"

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 served 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 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 [-] to [-] 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 a lot of 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 fields meet the blue sea water 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 much 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.

Chapter 1 Unforeseen Changes

Having said that, there will still be a wait.

It would take at least five days to replace the two days in the carriage with walking, not to mention that she still has luggage.There was no other big city around here, and she didn't want to spend the night by the side of the road tonight.

This wait is an hour.

The attendants also stopped several carriages, but either the carriages were too small to accommodate the three of them, or the other party was unwilling to take strangers on the road.

Mo Yun's bad premonition grew stronger.

At this moment, a convoy came into her field of vision, with a mahogany four-wheeled carriage at the head. Those who could afford this kind of carriage were either wealthy businessmen or noble families.Although the guard stepped forward to inquire as usual, Mo Yun knew that the possibility of the other party agreeing was very slim.Rich people don't care about the fare at all. Traveling in this car must be for comfort, and they are willing to discount their own feelings for the three people on the roadside.

However, the convoy slowly stopped.
