Ji Ping looked at the third salt furrow, thoughtfully, the white floc precipitated so quickly, and the nitrate plate thickened, I am afraid that it is not only natural settling, but should be accompanied by the chemical reaction between the white floc and the nitrate plate at the bottom of the pool.

Then Cui Jun pointed to the fourth salt furrow and said: "Finally, the ** will be introduced into the fourth furrow, the water is one foot deep, as long as the wind blows and the sun, salt flowers can be produced in five or six days, this is 'falling salt', the water is dry, and there is no bitter taste." ”

Ji Ping twisted out a few coarse salt grains in the last salt furrow, put them in his mouth and tasted them, sure enough, although the salt grains were still a little bitter, the taste was a hundred times stronger than the mined salt.

He couldn't help but admire the wisdom of the people and salt workers here, although they did not understand the chemical principle of the precipitation of impurities in the water of the salt pond, but they were able to summarize in their labor, and use the temperature difference of the four seasons to skillfully separate the miscanthus salt, white flocculent and other substances in it, which is really rare.

Cui Jun sighed: "However, although the salt produced by this method is good, it needs to go through cold and summer for a year, and the storage of brine is limited, and it takes a long time, which is not enough to supply the Quartet, so there is a large amount of salt, which is a bitter salt that is directly introduced into the pool to dry." ”

Ji Ping nodded, this method is very good, but with the help of the temperature difference of the four seasons, it is indeed a problem to take a long time, and he has no good way to deal with this shortcoming, his major in his previous life was not chemistry, and he did not understand the various chemical reactions in the process of salt making.

He looked around, looking at the patches of salt furrows of different sizes, and couldn't help but smile.

Although it is not possible to improve the salt production process, if these scattered salt furrows are integrated and connected together, the layout is reasonably divided. At the same time, it will be further widened, as long as the brine storage capacity of the first salt furrow can be expanded before winter. Then unify the process and implement the flow operation. That would also greatly increase the annual salt production.

Just thinking about it, a burst of singing suddenly came not far away: "The scent of the south wind can relieve the sorrow of our people, and when the south wind blows, it can relieve the wealth of our people......"

Ji Ping looked at the old salt worker on the side and said with a smile: "I don't think that among the salt workers, there are still people who can sing the songs made by Yu Shun in ancient times, it is really the hometown of culture." ”

The old salt worker laughed and said, "The general doesn't know, the salt worker here." can sing the 'song of the south wind', the south wind rises, the salt is born, and the south wind is really a godsend. ”

Ji Ping smiled and said, "Why did the elder say this? Although the south wind is good, is it not the east wind and the west wind that will help? ”

In his opinion, as long as it is wind, it can speed up steaming, and it should not be divided into southeast, northwest, and wind.

Unexpectedly, the old salt worker nodded and said, "That's right, the south wind is the best." The east wind is good, if you encounter a northeast wind or a southwest wind when drying salt, the brine will be 'porridge'. Like rice cereal, the salt produced is more bitter and unpalatable than the bitter salt that is harvested, so it is in the eyes of salt workers such as us. This south wind is indeed a gift from the heavens, and it must not be disrespected. ”

I heard the old saltman say this. Lu Zhi, Cui Jun and Yuan Ji on the side were all amazed, and they also agreed with the old salt worker's statement of 'God-given treasure'.

Ji Ping shook his head. The so-called south wind is warm, the north wind is cold, the east wind is wet, and the west wind is dry. ”

He naturally knows that temperature plays a very important role in many chemical reactions, and the difference between the southeast and northwest winds is mostly the difference between cold and warm currents.

After listening to Ji Ping's analysis, the old salt worker's body trembled, and he muttered: "The general's words are reasonable, think about it carefully, when the northeast wind and southwest wind come, the weather is mostly cold, I'm afraid that's exactly the case!" …… The brine is out of manganese in winter and blurred in summer, is it also because of the difference between cold and warm? ”

This old salt worker has been engaged in the salt industry for generations, with exquisite skills and rich experience, and after listening to Ji Ping's words, he suddenly realized and figured out a lot of truths.

Hearing the old salt worker's approval of what Ji Ping said, everyone who followed couldn't help but look at Ji Ping in surprise, especially those family stewards, they didn't expect this murderous, violent, treacherous and cunning young man to have such a wise cognition.

Lu Zhi, who has always been loyal and upright, couldn't help but sigh: "The lord can look at the surface and know the original, I might as well do it." ”

Ji Ping smiled and was about to speak, when the old saltman suddenly said: "General, there is one more thing, the grass people take the liberty to ask the general to discern it!" ”

"Oh?" Ji Ping looked at the old saltworker who was full of anticipation, and said with a smile: "Let's hear it." ”

At this moment, the sky suddenly darkened, and a rumbling thunder could be heard in the distance.

"It's broken! It's raining! ”

"Pain! What a pain! ”

……

Behind Ji Ping, the stewards of the major families sighed and became a mess, and Cui Jun on the side also said with a solemn face: "Lord, this salt is the most afraid of heavy rain and floods, once there is a flood in the pond on all sides, this year's salt drying will be a failure." ”

Hearing Cui Jun say this, Ji Ping's complexion also became solemn.

This time, he relocated nearly 400,000 people from Luoyang to the land of the two rivers and Shangdang County, and even though he started to farm now, the lack of grain will be a big problem during the period from this autumn and winter to the maturity of wheat tomorrow summer, and if he does not do it well, countless people will starve to death and cause chaos among the people.

His original plan was to occupy the salt pond and exchange salt for grain to survive the six-month period of food shortage, but if the salt pond also failed, I am afraid his plan would be in vain.

At this time, the old salt worker beside him looked at the clouds in the sky, but laughed unhurriedly: "The general doesn't have to worry, as long as someone brings rain gear to cover the rain, this rain will not last long, and it will not destroy the salt furrow, but it will fall just in time." ”

"Elders know the weather of the sky?" Ji Ping's solemn expression was relieved.

The old salt worker said with a bit of self-satisfaction: "Salt planters don't know the heavens, and they are mediocre." ”

When everyone heard the old salt worker say this, they relaxed a lot, and some of them still showed joy on their faces, muttering to themselves: "Could it be that God has blessed it again...... Rainwater salt ......"

On the side, Geng Zhong was in a hurry to get rain gear for Ji Ping.

In just a moment, the raindrops of beans fell down, the rain gear had not been taken, and there was no way to hide between the salt furrows, Geng Zhong and the two guards on the side hurriedly took off their coats to put them on Ji Ping.

Ji Ping shook his head to stop. Pointing to the old salt workers, Lu Zhi and Yuan Ji beside him, he said, "Put them on first." I am young and strong, so I am not afraid of thunderstorms, and I have a few guards to support them. Beware of slippery roads. ”

Among the people around him, the old salt worker was the oldest, nearly sixty, Lu Zhi was nearly fifty, and Yuan Ji was over forty, all of whom were in the prime of life.

As for himself, he was stronger than an ox. At the beginning, he fought repeatedly in the heavy rain in Luoyang, and ran for nearly 100 miles, but there was nothing to do.

Geng Zhong was stunned for a moment, and immediately executed Ji Ping's order, but he also put a piece of clothing on Ji Ping, and Ji Ping stuffed the little world on his shoulders into his arms.

Soon, another guard found a few hats, and Ji Ping also ordered them to put on Lu Zhi and the three of them first.

This little thing made Lu Zhi and Yuan Ji's eyes moist. Even the old salt worker was quite moved, and his eyes looked at Ji Ping much closer.

Even the stewards of the families behind them saw this scene and were thoughtful.

They suddenly appeared that this young man could be loyal to Yuan Ji, the head of the Yuan family in Huainan, and Lu Zhi, who was famous all over the world. It is no accident, nor is it just based on force and family background, just this scene in front of you. Many of them have faint expectations.

At this time, Ji Ping looked at the old salt worker again. He asked, "But I don't know what the elder just asked?" ”

The old salt worker laughed and said: "The general doesn't know, but in fact, he has experienced the salt from the four salt furrows. It's not the best salt. ”

Ji Ping was stunned: "Could it be that the elders have any other good methods?" ”

He had tasted the salt from the fourth furrow just now, and although it had been through winter and summer, it was still slightly bitter, and the quality of the salt was still much worse than that of later generations.

The old saltman pointed to the sky and said, "If you want to produce good salt, you must rely on the rain that falls from this sky, if this rain falls heavily and for a long time, and there will be floods on all sides, the salt furrows will be washed away, and the grains will be difficult to harvest." But if the rain is not too big or small, it falls into the fourth salt furrow, and the brine is combined, and after the rain stops, the brine dries, and the salt produced is the best salt, the grains, whiter than snowflakes, without a little bitterness, we and other salt workers call this kind of salt 'rain salt'. ”

"Rainwater salt?" Ji Ping couldn't help but raise his head, after experiencing the rain, the bitterness of the salt grains disappeared, and it must be that some of the impurities were separated again.

Looking at the rain falling from the sky, Ji Ping thought about why the rain fell into the brine, why he could once again separate the other components in the brine, so that the crystallized salt could eliminate the last bit of bitterness.

At this time, the old salt worker sighed: "It's just that this suitable rain is really rare, and most of it is either a big flood, or too small to help, so this high-quality salt also depends on God's gift." ”

Then the old salt worker looked at Ji Ping expectantly: "Why can the rain in this old world produce high-quality salt, I'm afraid only a strange person like the general can see through it." ”

Cui Jun, Yuan Ji, Lu Zhi and others on the side also lowered their eyebrows and thought hard, but they were okay with scriptures, but they were not so proficient in these natural principles.

The stewards of all the families behind them looked at Ji Ping, and they all showed expectant looks.

If this mysterious teenager can crack the mystery of "rainwater salt", then Hedong salt will inevitably have a reborn leap in terms of texture and yield, and then they can use salt to guide them, and they can also obtain great benefits.

To see things, we have to look at the essence, and Ji Ping was thinking about the essence of rain at this time.

Lu Zhi, Yuan Ji and Cui Jun thought for a while and were at a loss, so they raised their heads and looked at Ji Ping.

Today's Ji Ping seems to be omnipotent in their hearts, because since the beginning of the Luoyang crusade against Dong Zhuo, every time they face difficulties, no matter what, Ji Ping can always think of doing things that they can't think of doing, so they are willing to follow Ji Ping, and they are almost obedient to Ji Ping.

As Ji Ping walked, he stretched out his right hand, letting the cold rain fall on his palm, and soon his palm was filled with a handful of water.

Rainwater...... Rainwater...... Isn't it just water?

Ji Ping frowned slightly, unconsciously put the handful of rain in his right hand to his mouth and tasted it.

The rain tasted cool and diluted the bitterness of the salt in your mouth.

His heart moved, he lowered his body, stretched out his left hand to scoop some brine from the salt furrow, and tasted it.

The brine is slightly warm, bitter and salty.

One light, one bitter salty.

One is cold, the other is warm.

Thinking of some of the influencing factors in the chemical reaction, Ji Ping was thoughtful.

Lu Zhi and others may think that the rain falling from the sky is a mysterious thing, and the mystery cannot be explored, but Ji Ping knows that the rain is just water, and the difference between this rain and the brine in the pool is only that one is fresh water, the other is salt water, one is low temperature, and the other is high temperature.

This may involve issues of solubility and temperature.

Ji Ping didn't understand the principle of the chemical reaction, but he knew that there was something that could replace rain.

Under the same conditions, one is fresh water, one is slightly low, and rivers, streams, and springs are all fine!

He looked up through the rain curtain and looked at Nakajo Mountain, not far northeast of Yanchi, and his eyes became brighter and brighter.

When he rushed to Yanchi from Anyi, he saw that there were many rivers flowing out of Zhongtiao Mountain, including Qinglong River, Baisha River, Diaoya River, Wangyu River, Shushui River, the second largest river in Hedong in the north, and Ganquan Qingxi in Xie County in the west, which can undoubtedly replace rainwater.
