The industrial base of this era is really a bit hopeless, it can be said that there is nothing to want, and now, even the most commonly used drill bits cannot be found, what to do?

Yang Cong couldn't help but fall into deep thought, since the drill bit is not good, he can only make a fuss about the barrel material.

In addition to iron, what are the common metal materials, don't think about this problem, gold, silver, copper and iron, in addition to iron, the most common metal materials are naturally gold, silver and copper.

Is it okay to make a gun out of gold?

There is no need to think about this question, it must be possible, and in later generations, there are often rich people who show off their golden guns, which proves that there is definitely no problem with using gold as guns.

The problem is that gold is too valuable for even him to afford.

Silver is the same, it's okay to use it to make guns, but he can't afford it.

It seems that now the only way to replace it is with copper, although the copper at this time is not cheap, but the cost is barely within his affordability, of course, if there is a copper mine in Xuanfu Town, it would be better, in that case, there is no need to spend any money, as long as you invite someone to mine and smelt.

Thinking of this, he asked tentatively: "Sir, what do you think of why we should replace it with copper and use copper as the barrel?" ”

When Wang Xuan heard this, he couldn't help but be stunned, using copper as the barrel?

He really hasn't thought about this question, the main thing is that copper is money at this time, and copper coins are not made of copper.

However, there is nothing wrong with using copper for the barrel, because copper is much softer than iron, and it is not so cumbersome to process.

He pondered for a while, and then said carefully: "This is not much of a problem, but this copper itself is valuable, and the imperial court is also strictly controlled, I am afraid we will not be able to get so much copper to make the barrel of the gun." ”

This is not too big a problem, although copper is not as valuable as the national community, Yang Cong believes that Jiajing is not so stingy, as long as copper can be used instead of iron to make the barrel, he asked a little impatiently: "Is there a copper mine in Xuanfu Town?" ”

Wang Xuan thought for a while, and then said cautiously: "There is a copper mine near the Red Castle under the jurisdiction of the Longmen Guard, but it has been sealed by the imperial court, and the Red Castle is specially used to guard the copper mine. ”

Of course, Yang Cong understood what Wang Xuan meant, with the greed of the eunuchs, he couldn't do anything, and it was very likely that the people who contracted the copper mines over there would not only have to bear the taxes of the imperial court, but also give a part of the copper dug up to those greedy mine supervisors, so that naturally the pants for compensation would not be worn.

How to solve this problem, if he applies to Jiajing, Jiajing will definitely agree, but this mine supervisor must be indispensable, if he sends another Chen Hong's cronies, it will be miserable, and the means of coercion and temptation cannot be used all the time.

Meng Chong's one already made him scared, and if there was another one, he really didn't dare to coerce and lure, if it reached Jiajing's ears, he didn't know what Jiajing would think.

It seems that we still have to think of a way to let Jiajing not send Chen Hong's cronies over to prevent this troublesome thing from happening.

Yang Cong thought about it, then got up and said, "Okay, let's discuss here today, I'll find a way to get some copper over and make a sample." ”

With that, he turned and walked out.

There is also a reason why he is in such a hurry, because during this time, he is either blocking the Tartar cavalry in the dining room fort, or supervising the work in the Xuanhua Factory, and rarely goes home, Zhang Zhen and Lu Ling'er are a little unhappy.

Although these two wives didn't say anything, he saw that the clue was coming, anyway, he couldn't make a new copper musket at this time, so he simply chose to go back to the house to accompany his wife, and at the same time think about how to let Jiajing send a trouble-saving eunuch over.

There was no entertainment these days, and the way he accompanied his wife was to call both of them to the study, and then write and draw with them to enhance their relationship.

Zhang Zhen and Lu Linger heard that Yang Cong was going to accompany them to write and paint again, so they were naturally happy, and Lu Linger also deliberately showed off the results of practicing calligraphy in front of him.

It turned out that Yang Cong was not there these days, and Lu Linger was very bored, so she concentrated on practicing calligraphy, not to mention, she was still very good at concentrating, and she had made great progress in writing out her handwriting.

When Yang Cong saw her words, he couldn't help but move in his heart.

If you let her write a letter and secretly arrange Chen Hong and Meng Chong, then Jiajing will send a eunuch to think about it.

Thinking of this, he pretended to be surprised, and praised: "Oh, Ling'er's writing is really good, and there are some of the demeanors of everyone, I'm afraid that it will take more time than a husband." “

When Zhang Zhen heard this, she couldn't help but be full of doubts, how could Ling'er's words surpass you, you are a dignified champion.

When Lu Ling'er heard this, she jumped up from the chair happily and said happily: "Really, really, is my handwriting really so good?" ”

Yang Cong nodded without hesitation and said: "Of course it's true, if you write a letter and try it back, your parents, your brother, and the emperor will probably be full of praise." ”

As soon as he said this, Lu Ling'er became even more energetic, she hadn't written a letter to her family yet, writing a letter was such a fun thing, of course she wanted to try it.

However, when she took out the letter paper, picked up the pen, and was about to splash ink, she was embarrassed to find that there was no ink in her stomach at all, how should this letter be written?

Seeing this, Yang Cong immediately reminded: "Do you want your parents, do you want your brother, do you want the emperor?" ”

Lu Linger nodded again and again: "Of course I want to." ”

Yang Cong smiled and said: "Isn't this enough, you can also write about your life here, I believe your parents, your brother, and the emperor all want to know how you are doing here." ”

Lu Ling'er nodded again and again: "Well, yes, that's all I have to say." ”

However, she nodded and didn't write, because she still didn't know how to write.

Of course, this is not difficult for Yang Cong, he immediately began to teach Lu Linger how to express his thoughts, how to describe his life here, Zhang Zhen on the side also helped to come up with ideas, teaching her to describe some of her little daughter's thoughts, the three of them got together, you said, I said, and soon, Lu Linger wrote several pages with enthusiasm.

In the end, Yang Cong seemed to have inadvertently begun to complain about Meng Chong.

This dog eunuch is indeed too much, always stumbling there to prevent himself from opening mines, just because he accidentally offended Chen Hong at the beginning.

When Lu Ling'er heard this, she was naturally so angry that she immediately gritted her silver teeth and said that she wanted to sue this guy in front of the emperor.

So, under the guidance of Yang Cong, she choreographed Meng Chong and Chen Hong again.

As soon as this letter was written, Yang Cong immediately ordered someone to send it to the capital immediately after 800 miles.
