In order to be able to make more advanced things, Zhang Xiaobao and Wang Juan came to draw some drawings early the next morning, and asked people to order ceramics, waiting for the next person to take the order and leave, Zhang Xiaobao and Wang Juan had to study how to increase the temperature.

One is to supply air, the blast furnace will not be built by two people, according to the literal meaning, let people build a large furnace, especially a small building with a height of more than two floors, open on it, so that it can hold some raw materials, and the circle below and around it is empty, specifically for the purpose of putting fuel.

If there is no coal, then only charcoal can be used, and at the same time, in order to raise the temperature, some cooking oil is sprinkled into it, this is the only way that the two people can think of, with this method may fail to refine, may succeed, but the biggest is likely to explode, so this furnace was built in the most remote corner of the Zhuangzi.

"Xiaobao, did you say it would be successful then? What if the pressure resistance fails and an explosion occurs? "No matter how Wang Juan looks at this blast furnace, he feels unstable, and other people's blast furnaces are made of high-temperature resistant things, and their copycat version is really not safe.

Zhang Xiaobao didn't think that he could succeed once, this is not a fraud, just do it, if it doesn't work, it won't work, there is nothing negotiable, but he still has to do it.

"I don't know, I guess the failure may be the greatest, nothing, any progress is the end of experience in failure, I mean, invite all those people who fire ceramics, let them work a little hard, and the blacksmith, it's nothing more than temperature and some added things."

"Well, let people pay attention to safety, there is hope for people to live, and when things are gone, it is nothing more than the retransformation of matter, and for us it is a matter of money." Wang Juan felt that this was the case, even if he knew that he would fail, he had to do it.

The speed of making things is not slow, a few days later, some equipment was sent over, some iron, and ceramics, for this Zhang Xiaobao took out hundreds of silk, that is, dozens of taels of silver, not much.

Experiments began after the arrival of these things, accompanied by explosions, and the equipment purchased broke one after another, and for two days there was no good news other than knowing that there were no casualties.

Zhang Xiaobao and Wang Juan would take time to come over every day to take a look, for fear of hurting people, even if the equipment exploded, it was just money, but people were very expensive to the two of them.

As the sound sounded again and again, everyone was numb, Zhang Xiaobao and Wang Juan were looking forward to one being successful, and the others were doing it mechanically, which was not in line with the nature of scientific research, but Zhang Xiaobao and the two had no choice, everyone was here to work, and you couldn't ask for it as a scientist.

When another explosion sounded, the blast furnace also exploded, Zhang Xiaobao and Wang Juan asked everyone not to go over first, and waited for half an hour before they came to the front to watch.

"Little boy, everything is broken, there is only this one left, there is nothing to do, can this be used?" A person from Zhuangzi picked out something from the ruins, carried it to Zhang Xiaobao and Wang Juan and said.

Zhang Xiaobao and Wang Juan took a look and found that the furnace suitable for iron was well sealed and did not explode, so they called a blacksmith and asked, "Why can this still be preserved intact?" ”

The blacksmith is more experienced, checked it, and replied: "The wall of this one is a little thick, which apprentice should have done it, it was not done well at all, and when the apprentice was making seals, his craftsmanship was also a little worse, and he actually sealed them with lead, instead of sealing them directly with the method of striking iron like some blacksmiths with good skills." ”

"Oh, I see, it's sealed with lead, and the walls are thickened, well, good thing, fire welding is not done now, we can only continue to build blast furnace experiments, but this thing is very useful, find that apprentice, let's see."

Steward Zhang heard the whisper of the little boy at this time, and said to the blacksmith, he didn't know what the little boy wanted such a waste apprentice to do.

What he said made the blacksmith frightened, and begged: "Steward Zhang, an apprentice, this kid is usually doing things well, and he is filial, you have a lot of adults, let this child go." ”

The blacksmith thought that Steward Zhang was going to find trouble with the child, even if the apprentice was not from the Zhang family's Zhuangzi, it was still very easy for such a big Zhuangzi to clean up an ordinary person.

Steward Zhang didn't know what to say for a while, and then looked at the little boy standing next to him, Zhang Xiaobao felt that there were still some inconsistencies between Steward Zhang and him, and he couldn't understand his intentions, shook his head slightly, and waved his hand again.

When Steward Zhang saw these two actions of the little boy, he immediately thought about it, what does it mean, according to the normal way, this is the meaning of refusal, of course, the refusal is the blacksmith's plea, but when it is in the past, the little boy and the little lady will not do this to others.

The two little ancestors never did that kind of thing to kill everything, they were good to the people in the courtyard, so good that they could leave oil lamps for every person who kept vigil in every house, and they could provide at least four meals for everyone who worked a lot, and they were good for the villagers, and the things that were sent during the festival were all paid by the two young men.

It's not bad for outsiders, those officials in the yamen, they can care about everyone's heads, and yesterday they also sent five yuan of ginseng to a yagong's home, the father of the yagong is sick and needs this thing, five yuan, it was bought for 800 yuan, and people rode a fast horse on the Zhuangzi, and rushed all the way to the yagong to send it home.

If the little boy can do this, can't he tolerate an apprentice? This is absolutely impossible, so why is it shaking the head and gesturing again?

"Steward Zhang, you are doing well, that apprentice is the son of an old friend of mine, if you really want to find any fault, just find mine, I will take it for him." The blacksmith looked at Steward Zhang standing there silently, he was really anxious, so he almost knelt down and begged.

Steward Zhang hummed and dealt with the blacksmith, and looked at the little boy again, Zhang Xiaobao is angry now, you can't understand the intention of the master, what are you doing? I usually have no less contact, and I will go to my yard at least once a day to see it, and if it is replaced by a little red, cherry, and pomegranate, I would have known it a long time ago.

In desperation, I had to pick up the charcoal strips that flew here from the ground, and wrote the word 'recruit' on my clothes, and as soon as I finished writing, I blurred them with my hands.

This did not affect Steward Zhang's judgment, seeing the two words, he understood, and said to the blacksmith: "Ai blacksmith, don't worry, it's not to trouble your apprentice, you see, other people's things are broken, it's okay for your apprentice to do it, this is to find your apprentice, ask him well, not only will it not harm him, but it will also give him benefits." ”

"Really? It's not like you're going to trick him into coming in and then clean him up, right? The blacksmith was clearly still not at ease.

Steward Zhang's face sank, and his eyes glared, "Blacksmith Ai, what do you want?" When I Zhangjia Zhuangzi will go back on his word? ”

"Don't dare, don't dare, Zhangjia Zhuangzi has never done such a thing, well, go back in a while, let that bad guy come over." When the blacksmith saw Steward Zhang like this, he no longer doubted that so many people around him were listening, how could Zhang's Zhuangzi trick someone to come over.

In the afternoon, the apprentice came, and when he came, he was still worried and didn't know what he was going to face, so Steward Zhang personally took him in, first let people serve tea, and said a lot of praise.

"Steward Zhang, is there something you asked me for?" The apprentice finally couldn't help it anymore and asked what was in his heart.

"Well, in fact, it's not a big deal, the thing you made is good, the master has taken a fancy to it, let you make another one according to this diagram, the seal is still as you think, use lead, and at the same time make the thing thicker, you can take a look."

Steward Zhang took a piece of paper from the side, on which something was drawn, and sent it to the apprentice for him to see.

The apprentice can still understand this little thing, but after reading it, he didn't know what it was for, and raised his head to look at Steward Zhang suspiciously.

"What? Can't do it? Steward Zhang asked.

"Yes, this thing is simple, it can be made in two days, but I don't know what the use of this thing is?" The apprentice hurriedly agreed, and when he saw the picture, he found that it was really very simple, especially without considering how to make the four walls thinner.

"Well, that's good, it's your salary." Steward Zhang took out two large strings of copper coins from the side and put them on the table, making a loud noise.

The apprentice hurriedly stood up in fright, not daring to look at the money, it turned out to be two pieces of money, if it is a normal government exchange for silver, it can be exchanged for two taels of silver, but in terms of spending, it can be used for two and a half pieces of silver, how can you get so much money for such a thing?

"What's wrong? Think it's less? This little bit of silver will be given to you. Steward Zhang threw a piece of silver beans on the table that amounted to nearly five yuan.

The silver bean fell on the table, and kept spinning, making a slight rattling sound, and the apprentice's eyes couldn't help but look at the silver bean, he knew that this bit of silver was not as much as the two dollars, but he still liked the feeling of holding the silver in his hand.

"Enough, enough, not enough, it's too much, this, take some back, it won't take so much, that bit of silver is already too much." The apprentice waited for the silver bean's rotation to stop, and then said in a little panic.

Steward Zhang nodded with satisfaction, "It's enough, take it all, remember to do that thing well, and no matter who asks, you can't tell others how to make this thing, except for Zhangjia Zhuangzi, you are not allowed to do the same thing for other people in your life, you can't do it yourself, understand?" ”

"Understood, understood, Steward Zhang, don't worry, I'll forget it when I'm done, and I can't remember it anymore." The apprentice immediately understood that the money also included the seal.
