The sun is shining brightly, and the wind is beautiful. Wu Yanzhi held a grand funeral for the fallen cavalry. He personally presided over the funeral and invited the Qingyun Taoist chief of the nearby Taoist temple to do the ritual and surpass the dead.

"In my own name, write a letter to each of their families, and if there is a family member who needs to be taken care of, let them bring it up, and we will ask the county and the village to help. The cavalrymen who died in battle were uniformly awarded according to the six transfers, that is, the captains of the cavalry. ”

Wu Yanzhi thought, although there will always be casualties in the war, but these soldiers are very hardworking, and they have to make their families live a little better. If you can, try to help as much as you can. After having a high-ranking position, the family has great benefits in terms of taxes and sons' entry into the ranks.

"General Wu treats the soldiers so kindly, they must be very grateful. General Xiang Wu, a general who eats, lives and sleeps with soldiers every day, his subordinates have never heard of it. Yang Siqiao praised beside him.

"Well, this is a trivial matter, and it is very difficult for the brothers. Also, Brother Yang has made a great contribution this time, and I estimate that he will be promoted soon. ”

"It's all up to General Wu to promote! Without General Wu, there would be no subordinates Today, the subordinates will never forget the great virtue of General Wu! However, General Wu, will the Holy Lord agree to the proposal to set up the Three Surrendered Cities? Yang Siqiao asked.

"I think it should be, the saint is the first empress of the ages, and he set up the four towns of Anxi, which is the work of thousands of generations. The establishment of the Three Surrender Cities and the establishment of the Anbei Metropolitan Protectorate have such great benefits, she should agree. Wu Yanzhi is very confident.

Wu Zetian is not an ordinary person, and he took the opportunity of his great victory over the Turks to consolidate the Hequ region. The meandering area is consolidated, and Guanzhong is self-sufficient.

After the funeral, Wu Yanzhi went to visit dozens of wounded soldiers. Most of these soldiers' injuries were not too serious, and Wu Yanzhi hurriedly distilled some alcohol to disinfect them.

Under normal circumstances, they are not life-threatening and do not injure vital organs.

In the afternoon, he led dozens of cavalry to another salt lake, where natural soda ash is said to be located. Someone found soda ash under a salt layer four or five meters thick, and it was once collected.

He went to the pit where he was gathering, and saw that there were two peasant women digging there.

When he went down to the pit, he grabbed a few pieces and looked at them carefully, and tasted them with his mouth, and it was indeed soda ash. However, there are some impurities, mainly some salts.

It is necessary to use the saturated solution method and re-refine it to obtain relatively pure soda ash - sodium carbonate, which we commonly call baking soda.

The so-called cooling heat saturation crystallization method is also known as cooling crystallization method. It is a method of separating or purifying solid substances according to the different solubility of substances at different temperatures, generally with high solubility at high temperature and low solubility at low temperature.

This method is mainly used for substances whose solubility decreases significantly with the decrease of temperature, first evaporated and concentrated, and then cooled. At this time, only the solubility of the substance changes greatly with temperature, and its solubility becomes smaller and smaller, and at this time it crystallizes and precipitates.

For example, sodium carbonate, which precipitates before sodium chloride, is of course very pure. Not only sodium carbonate, but also potassium nitrate, which is used to make gunpowder, is also purified by this method, and the effect is very good.

Because whether it is sodium carbonate or potassium nitrate, the solubility of the two varies greatly depending on the temperature, while the salt content such as sodium chloride has little effect.

"Qi Xuan, you can arrange it, and use this salt lake to mine natural soda ash. Arrange for my two guards to be in charge, and the migrant workers will be recruited nearby.

All the soda ash mined was transported to Taiyuan, and a glaze factory was established in Taiyuan to strive for a few months to produce 100,000 pieces of glaze. ”

100,000 in a few months? Qi Xuan and several staff members and guards next to him heard it, this is too exaggerated, right?

However, they knew that Wu Yanzhi's plan was not yet unrealizable. If they can earn 100,000 yuan in a few months, their rewards will definitely be indispensable.

So everyone was naturally very excited, and several guards took the initiative to ask for soda ash mining.

"Don't worry, Qi Sima will arrange this matter in detail. Everyone follows me, and they do the same thing everywhere, and I won't treat anyone who follows me badly anyway. Wu Yan saw that they were very excited, so he smiled and persuaded them.

"General Wu, how much soda ash should we mine?" Qi Xuan asked.

"We can continue mining and recruit local people to do things in the future. This production of high-end glass products, but it can be done for decades and hundreds of years, maybe a thousand years later, what are you afraid of? Wu Yanzhi said with a smile.

Everyone nodded yes. At this time, it was a high-end glazed product, and it was rare in the palace, even the richest man in the Great Zhou Dynasty, Zou Camel, there were not many in the house.

Of course, it is better to transport it back after purifying it here, which can greatly reduce the amount of transportation. So Wu Yanzhi and the others returned to the city and found County Lieutenant Li. Let him help find a place to prepare for the establishment of a workshop for refining soda ash.

Next, Wu Yanzhi began to teach them how to refine soda ash: "You have to make a few large iron pots first, and then melt the natural soda ash brought back from the salt lake in water.

Then put it in a large iron pot to burn, burn to a certain extent, and then cool down, then the first to form a crystal is soda ash, that is, what we want. ”

As soon as everyone heard it, there was no technology to speak of this thing, it was just a matter of mastering a heating time.

The guards were eager to try again, and they all wanted to fight for this opportunity. This is also understandable, they were originally farmers, but they liked to do these kinds of work.

This is Qi Xuan said with a smile: "General Wu, I think it's good to leave Zhang Wei alone, and then find two helpers here, with the help of County Lieutenant Li to watch this place, it should be foolproof." ”

When County Lieutenant Li heard this, he was very willing to help Wu Yanzhi: "General Wu, Qi Sima, this kind of trivial matter is handed over to his subordinates." The lowly must find someone to help transport it to the crossing of the big river. ”

Of course, he was very happy to be able to do things for Wu Yanzhi. After climbing into a relationship with him, are you still worried about future promotions?

Wu Yanzhi said: "Okay, then it's troublesome County Lieutenant Li." ”

"It's a trivial matter."

"How far is the blacksmith from this place? It's been a long time since I've seen my old job. Yao Kuan smiled.

His injuries were very light, just some flesh and skin, and some herbs to wrap up, and it was fine.

"It's just a street next to it, a few dozen steps away, and it's just a small county town." County Lieutenant Li said.

The group talked and laughed and went to the blacksmith shop, the blacksmith king blacksmith, and when he saw so many people coming, he was very surprised, and he didn't know what was going on.

"Master Wang, don't panic, this is General Wu, they just want you to fight a few big iron pots. You have to fight a little harder, hold on a little tighter, General Wu will use them soon. Li County Lieutenant said.

When he heard that he was going to make a large iron pot, the blacksmith had never seen it, so he asked for some details.

Wu Yanzhi told him in detail about the appearance of the iron pot he wanted. When he heard it, this thing was too simple. Please Baidu "Throw Book Network" Thank you for your support!
