Someone next to him took the principal out. Wu Yanzhi still looked at the remaining two people coldly: "Director Liang must bear the corresponding management responsibility, because you are the chief."

first Ge went to the post of director, and investigated Yiyang County; After the results of the investigation in Yiyang County come out, it will be reported to the heavenly officials for processing.

Supervisor Deng is cautious in doing things, and you will act as the principal for the time being. In addition, you immediately recommend one of the competent officials under you to act as a supervisor temporarily; I will recommend you both to the imperial court for a principal position.

I'll transfer another supervisor from Yiyang Metallurgical Supervisor, and you'll have all of you. From now on, we must act in strict accordance with the laws of the imperial court! ”

"I thank Wu Shaoqing for his trust, and I will definitely live up to my mission!" Supervisor Deng saw that he was fine, and he was promoted, so he was naturally overjoyed.

Looking at the person in charge of Na Liang again, his face was pale, trembling, and he didn't say a word.

Wu Yanzhi asked his subordinates to grasp all the evidence, and this thing may be used in the future. However, now that there are so many things about Wu Yan, where can I have time to deal with Ji Yanne?

As for Na Liang, even if there is no corruption and perversion of the law, according to the regulations, he will definitely be punished.

……

Early the next morning, Wu Yanzhi said goodbye to the acting director Deng Jianzuo and others, and the group rode to the lead mountain field.

Because of his university major, he is very familiar with the country's major mineral resources. And before he came here, he had carefully read the information of Leping Xingli Field, Yinshan, and Yiyang Lead Mountain Field in Shangfangjian.

The copper resources of the lead mountain field are far better than that of Xinglichang, where copper mining has been going on since the Jin Dynasty. Of course, there is no bile water copper smelting technology!

The bile water (copper sulfate, CuSO4) is actually a copper-containing solution leached by acidic water from the copper ore.

The lead mountain farm produced more than 200,000 catties of copper last year, and it is also an important lead producing area in the country, with an output of more than 180,000 catties last year.

Of course, because this is a lead-zinc mine, and they don't produce zinc. As soon as I came, I had to start smelting a large amount of zinc, and it was estimated that there would be no problem with at least four or five hundred thousand catties a year.

There is a metallurgical supervisor in this Yiyang County, who is responsible for the management of copper, lead, and silver in the vicinity.

From Yinshan to Yiyang, there are two roads, one is to take Yugan, from Yushuirao, bypass Huaiyu Mountain, that takes seven days to arrive.

The second road is to take the path in the mountains and forests, directly over the Huaiyu Mountain, which is more than 1,000 meters high, which is very dangerous, because tigers, leopards, and bears are often infested in the mountains.

Wu Yanzhi and them have a total of six people, Yinchang sent four guides and guards, plus Yufei and Yao Kuan are brave people, but they are not afraid of any tigers and leopards.

I lit a fire in the evening, spent the night in the mountains, and arrived in Yiyang County at noon on the second day. The county seat is located on the edge of the Yushui River, which is still dozens of miles away from the lead mountain field.

They still live in the Yiyang County Post House, and when they heard that the Qin mission was coming, several county officials in the county naturally came here to greet them, and soon, several officials from the Yiyang Yejian also arrived.

Everyone chatted, but Wu Yanzhi roughly asked, how long will it take to turn around the copper field tomorrow. Metallurgical supervisor Liu Jian replied: "Qi Wu Shaoqing, the copper field here has a large range, and it will take at least three days to see it!" ”

Wu Yanzhi: "Then two days, depending on the weather, it won't rain." After lunch, we set off, and in the evening we will find a big family near the lead mountain field to rest! ”

"This ...... Okay, the arrangement between the humble post and the Li County Order is that I heard that Ambassador Wu was sleeping in the mountains last night, I am afraid that he is too tired! "Then Eunuch Liu never thought that a four-grade Shaoqing would be willing to sleep in the mountains and forests.

……

At night, at the foot of the lead mountain, a landlord surnamed Cheng stayed overnight, but the landlord was so happy that the yard in the house was cleaned three times, and he still felt that it was not clean enough.

Where has he ever seen such a big official?

Wu Yanzhi ate at his house and gave the money for the meal as usual, of course, they didn't accept it. In the end, Wu Yanzhi wrote a pair of words to his family as a commemoration. But he made the master so happy that he didn't sleep for a few days.

On the second day, early in the morning, the mountain was raised.

Liu Jian gave a detailed introduction to the situation: "Qi Wu Shaoqing! Inspector Cui personally came here to investigate the number of bile water springs, and after a second verification, two new springs were found. Below, let's take a closer look:

There are 156 large springs in Lead Mountain, and 77 drinking water pipes have been installed at present, totaling 230 troughs. Each pond is a pool, with the height of the terrain, each pool or two or three ditches, or to more than ten ditches.

After detailed observation of the inferior grades, this bile water ore is divided into three grades: high-grade, bile water immersion, mineral red; medium, bile alum-soaked, mineral-purple; Inferior, alum immersed, mineral yellow. ”

"Very good, your preliminary work is more solid, and I am more satisfied. You used to mine and smelt more than 20 catties of copper, and after this bile water is started, I estimate that there is no problem with 1 million catties a year.

Remember, in the past few years, we must increase production at full capacity, and we will work for ten or eight years first. Even that copper ore can be excavated in large quantities. As I said, whoever manages the smelting supervisor whose output increases high, I will give him a higher and lower examination, and there is no problem in getting promoted! ”

Upon hearing this, the few metallurgical officials who followed were very excited. Liu Jian said: "Please rest assured, the ambassador, I will add 500,000 catties this year." Even if you live on this mountain every day, you have to complete the task! ”

"Good!" Wu Yanzhi was very satisfied with his statement!

He had already boasted about Haikou in front of Wu Zetian, and of course he had to strive to exceed the task. There are no problems with the exploitation of bile water here for decades.

Besides, copper mines, iron mines, tin mines, and lead-zinc mines in Yunnan and Sichuan are everywhere. As soon as the production of bile water this year rises, the emperor believes him, and he will send more than a dozen inspectors to the whole country next year to carry out large-scale mining.

Now it's only 2 million catties of copper a year, which is too little, 50 million catties a year is about the same!

Is it more than 50 million catties? It's not much, it's actually only 25,000 tons. In my previous life, the year I came, the national copper output was 1.75 million tons.

If 50 million catties can't be completed, plus zinc smelting brass, it will be easy.

……

"How many catties of lead can be produced this year? Is there 300,000 catties? Wu Yanzhi asked.

"Almost, now in the first eight months, 200,000 catties have been produced!"

"That's good! You don't have to look here, go, go back, I'll teach you how to smelt zinc! ”

"Good!" A few people were excited! Because Inspector Cui had already told them about Wu Yanzhi's intention to teach zinc smelting!

This is the secret recipe for smelting "鍮".

On the same day, he rushed back to Yiyang County. After dinner, Wu Yanzhi showed them the pattern of the "zinc smelting tank" drawn before, and explained the operation essentials in detail.

These people are all masters of smelting copper and iron, but they just know the secrets. Wu Yanyi said that they naturally quickly became familiar with the technical points.

After staying here for another two days, Wu Yanzhi made a few samples of zinc-smelting cans made of clay.

He explained the technical points in detail with this mold sample, and left the place the next day, and he was going back to test gunpowder.
