I did not expect the old saltman to look at the clouds in the sky, but he laughed slowly: "The general does not have to worry, just let people take the rain gear to cover the rain, this rain will not last long, will not destroy the salt, but it will fall in time."

“Do seniors know the weather?”Zhang Liao froze.

The old salt workers are somewhat self-satisfied: "The salt-burner does not know the sky, and he is philistine."

Looking at the old salt workers a look more powerful than the name, Zhang Liao can not help but speechless, Guo Jia laughed, even the hustle and bustle.

At this time, Wang Yi returned to God, looked at the old salt workers, and said with joy: "Is it God's blessing, but it can become rain salt?"

The old salt worker said, “That’s it.”

Zhang Liao was not surprised: “What is rain salt?”

Wang Yi said, "The general does not know anything, after four salts and salts, but it is not the best salt."

“Oh?”He said, “What’s the point?”

He had just tasted the salt in the fourth bast, although it was winter and summer, but it was still slightly bitter, and the quality of the salt in the future life was still much worse.

Wang Yi pointed to the rain clouds in the sky and said, "When the salt is sunded, if the salt is in the event of heavy rain, the salt is dissolved, and the saline work is destroyed once, if it is light rain, the more vivid the color is, the better the salt, this is called rain salt, it is very rare."

At this time, the old salt workers also said: "The grass people have to ask the general this thing, as the county said, to produce good salt, but also rely on the rain in the old world, this rain if it is big, down for a long time, not only the salt is difficult to dry, once the flood is launched on all sides, the salt will be destroyed, the particles are difficult to collect."But if the rain falls not too small, it falls into the fourth salt, and when the rain stops, the brine is dried, and the salt produced is the best salt, the grain, which is whiter than the snowflake, and there is no bitterness, I wait for the salt workers to call this salt, "rain salt."

At this time, the sky has fallen raindrops, the guard borrowed the rhododendron from the nearby salt workers, Zhang Liao let them first give the old salt workers and the old salt workers and hoop, Guo Jia, Wang Yi and others covered, he felt the rain falling in the sky, his mouth said rain salt.

At this time, the old salt worker sighed: "But this suitable rain is really rare, most of them are not too big to flood, or too small to help, so this good salt depends on the gift of God."

He looked forward to looking at Zhang Liao: "This old world of rain, why can produce good salt, I am afraid that only the general such a strange person can see it clearly."

On the side of the hustle and Guo Jia and others heard the words, are contemplative, but although they are proficient in politics and scripture, more wisdom, but they are not so proficient in these natural reasons, and are affected by the induction of God's thoughts, it is difficult to understand these mysteries.

I can't think of it for a while, so they can't help but look at Zhang Liao.

Now the perception of Zhang Liao is getting better and better, this Lord can not only fight, but also love the people, longer than the government, have benevolence, and have the amount of heart, dare to dare to dare to dare to decentralization, and have insight into things, so that they can't see the dust.

If this rainwater salt is destroyed by Zhang Liao, the salt in the east of the river will inevitably have a qualitative leap on the geological level, so that the reputation of the salt in the east of the river is in the world, and it is more beneficial to the people, Ze and future generations, after all, the bitter salt is harmful to the body.

Looking at things to see the essence, this is Zhang Liao's view, he is thinking about the nature of rain and salt.

Rainwater salt, is through the rain, the salt particles of the sun are bitterly removed, which must be some of the impurities are separated again.But why does this rain fall into brine again, and once again, the other components of the brine can be separated, so that the crystallized salt will be removed from the last bit of bitterness?

The key to this is the rain, so what is the essence of rain?

Zhang Liao walked, while extending his hand, allowing the cold rain to fall on the hand, and soon the hand was full of water.

Rain... rain... not water?

Others may think that the rain falls, which is a mysterious thing, and it cannot solve the mystery, but Zhang Liao knows that rain is only water.

And when the people were watching, he put the rain in his hand to his mouth and tasted it.

The rain smelled cool, and diluted the bitterness of the salt grains that had just been tasted in the mouth.

He moved his heart, lowered his body, stretched out his other hand, and took some brine from the salt and tasted it.

The water is a little warm and salty.

One light, one salty.One cold, one warm.

Thinking of some of the influencing factors in chemical reactions, Zhang Liao thought about it.

The difference between this rainwater and brine in the pool is that one is fresh water, one is salt water, one is low temperature, and one is high.

This may involve the solubility and temperature, his knowledge of chemistry has long forgotten to go to the clawed country, but although he does not understand the principle of chemical reaction, but he knows that there is something to replace rain.

The same conditions, fresh water, low temperature, river water, brooks, springs can do!

He looked up through the rain curtain, looking at the north side of the salt pond, he came to see that there is a Gan Spring, the taste of Gantong, but was introduced to the salt pond by the salt workers, not in the salt, and in the south of the Zhongzhang Mountain, the western part of the county, there are also several Ganquan Qingxi, these can undoubtedly replace the rain.

At present, the most important thing is to verify your own guess first, and see that it cannot be seen.

Six days later, the sun shines on the earth, and the south wind blows.

By the side of the salt pond, Zhang Liao, Ying Yi, Guo Jia and hundreds of salt workers gathered here to watch a clear water flow along a canal.

This canal is just opened in recent days, the bottom of the canal is a new cement, the source is not far north of the salt pond Ganquan, flowing to a salt, this is to verify Zhang Liao's speculation on the "rain salt" mystery.

This salt belongs to the fourth salt, which is brine, and in the sunlight, the brine has begun to spread salt flowers, and is at the time of crystallized raw salt.

The canal is not directly flowing into the salt, but is connected by three small channels between the salt, which corresponds to the three inlet of the salt, and the opening of three small canals and three inlets is for the uniform intersection of fresh water and brine.

Because when it rains, rain and brine belong to the most uniform intersection, and now Zhang Liao can only imitate this form, in order to verify this mystery, he can be said to have some of them considered.

And there are clean stones and cloth groups in small channels, which is to filter impurities in the stream water and ensure the cleanliness of fresh water.

“Water!”

With the order of Zhang Liao, the three efficators on the southern side of the canal were opened at the same time, and the spring water in the canal flowed to the salt silt along three small canals.

The experienced old saltman took four or five salt workers, and measured the depth of the water in the salt with a wooden ruler, nervous and expectant to watch the spring slowly flow.

This is also Zhang Liao's command, he believes that brine and fresh water mixed out of salt, there must be a most suitable proportion, more or less can not achieve the effect, as the old salt workers said, the historical "rain and salt" also need to be just the right amount of rain to produce, rainstorms and light rain can not.

Zhang Liao can not measure the proportion of fresh water and brine, but he used a magic method, when it rained on the day, he first used a wooden ruler to measure the depth of brine before the rain, and measured the depth of the water after the rain, about the mixture of rain and brine, and fortunately that the precipitation on that day did indeed produce rainwater salt, Zhang Liao used this ratio to verify.

His measurement of proportions, so that people are desperate, and this method can be used in many aspects of agriculture, calculation, etc., and can be promoted.

With the spring water flowing into the salt, the salt flowers that were originally produced by the brine in the salt slowly disappeared, and the coarse salt that had been crystallized was dissolved again.

In the attention of countless people, time slowly passed, the water reached a scale of wood, several salt workers shouted "stop the water" at the same time, several salt workers rushed to plug the water.

The old salt worker went ashore, looked at the sun overhead, and said to Zhang Liao: "General, go back to rest, the sun is violent in the afternoon, it is not appropriate to stay, this afternoon, you can start to grow salt."

Zhang Liao shook his head and smiled, "I'm afraid you're not in the mood to rest, I'll wait here."

Hedong County is a low-lying basin, at this time, although it is early summer, the weather is extremely hot, but Zhang Liao and others really do not have the intention to go back to rest, those salt workers are the same.

In the expectation of the people, the time slowly reached the afternoon, the water level in the salt fell slowly, and the water began to produce salt flowers.

After nearly an hour, more and more salt grains are produced under the water.

Zhang Liao had not yet spoken, and the old salt workers on the side could not help jumping into the salt, fished out a handful of salt grains from the bottom of the water, and put them in their mouths to taste.

The old saltman’s tears suddenly flowed down.

“Isn’t it possible?”When people saw this situation, they were disappointed, but they saw the old salt workers kneeling in the water toward Zhang Liao, and hissed: "It is done!It has become!The rain is salt!The heavens have eyes, and the wise have waited for me.”

It has become!Hundreds of people cheered in unison around the salt pond.

The success of rainwater salt is very important to them!

You know, in the time of the Three Emperors and the Five Emperors, the people took salt from the salt pond in the east of the river, and together with boiling water and boiling salt, these two ancient and clumsy methods lasted for thousands of years, until the end of the Warring States, people explored the method of salt and salt.

And from the salt drying method, to the four salts, and after hundreds of years, to reach the current situation, but still clutter, uneven salt, relying on the sky, the limit is too large, the yield is not high.

But this development process has gone through thousands of years, and there are countless people's exploration, which can be described as long and difficult.

Today, under the attempt of Zhang Liao, even through artificial means, rainwater salt, excellent refined salt, how can people not like it?

Qilu land has seawater boiled salt, but the process is extremely complex, the cost is extremely high, the cool place has well salt, but the yield is low and the cost is high.Although the salt of the river is good, it is deficient and depends on the sky.

The successful trial production of rainwater salt, Hedong salt no longer need to rely on the sky, which marks that the salt of Hedong has truly become the world's first salt, regardless of production, texture, or cost!

At this time, even the ever-steady yupling was full of ecstasy, and as for Guo Jia, he shouted and drank a lot of people to throw Zhang Liao up and cheer.
