When the sacrifice was over, the nineteenth princess left with the people, leaving only blacksmith Li and two female guards to help Zhu Xiaobao! Didn't people say it, the ancestral stunt, of course, must be kept secret! At this point, the nineteenth princess still respects Zhu Xiaobao very much! Of course, even if she is on the scene, she may not be able to understand it!

In fact, the soil method coking and blast furnace ironmaking used by Zhu Xiaobao are the simplest, and from the current point of view, it is completely inefficient and polluting equipment, which should be completely eliminated! But here it's a high-tech thing! At least it's the most advanced now!

This small blast furnace is easier than that cellar furnace, because it is not large, but the sparrows are small and have all kinds of organs! This blast furnace is also divided into throat, body, waist, belly, and cylinder. At the bottom, there are tapholes and slag outlets, and a little higher is the air duct between the hot air nozzle and the middle section of the hot air pipe, which is also heated with coal!

The top is the feed port, and this key part is controlled by Zhu Xiaobao himself, and Blacksmith Li is only responsible for pulling the bellows below. And the two female guards who helped Zhu Xiaobao feed were Wu Lijia and Ying Xiuxiu! The two of them are now the two female guards that Zhu Xiaobao is most familiar with, and their relationship is also the most harmonious!

That Ying Xiuxiu was taken advantage of by Zhu Xiaobao! But every time he blushed with a shy face, he let Zhu Xiaobao succeed! So Zhu Xiaobao likes to do things with Ying Xiuxiu very much! Of course, although Zhu Xiaobao always takes advantage of herself, Ying Xiuxiu also likes to do things with Zhu Xiaobao very much, because Zhu Xiaobao is so talented, and she feels a surprise from time to time!

But the three people present today all looked solemn, and their bodies were already soaked with sweat, don't look at the long away and use the extended shovel to feed, but the temperature is also high and scary! He was still wearing thick coarse cloth clothes! I'm afraid of being splashed. Steelworkers are miserable!

The key question is what kind of situation is in the blast furnace and what kind of temperature it has reached! Zhu Xiaobao didn't know at all, he could only rely on Blacksmith Li's experience in this regard, although he had never burned to such a high temperature, but his perception of temperature still far exceeded Zhu Xiaobao!

When Blacksmith Li thought it was about the same, he poured the iron ore, coke and limestone in batches. According to the equation, iron and carbon dioxide should be produced after heating at high temperatures. But this is only theoretical knowledge, and the actual effect still depends on the results!

In the middle, Zhu Xiaobao is also a little nervous, and the only confidence is that his theoretical knowledge will never be wrong! After two hours of waiting, the first furnace of molten iron slowly flowed out of the outlet, and below was a long mold that had been made long ago, so that the shape of the molten iron after cooling was different strips of different lengths!

Blacksmith Li was stunned when he watched from the sidelines, it was the first time he had seen it if it could melt into molten iron! For the magical little fat man in front of him, Blacksmith Li felt admiration from the bottom of his heart!

Now that the molten iron has flowed out, then his plan should be considered a success! Zhu Xiaobao finally breathed a sigh of relief! Then it's simple, according to the experience just now, more than 1,000 catties of iron ore have been poured into the blast furnace one after another! The efficiency of his simple blast furnace is not high, and the iron ore he bought is not the best, so the pure iron obtained from a thousand catties of iron ore is only 500 catties! And there are a lot of impurities, and the color is not pure iron's silvery-white, with a great degree of gray!

But this has already made Zhu Xiaobao very satisfied, which is much stronger than the iron tire that Xia Zhen'er said he bought from Yueling Mountain! Even Blacksmith Li knows that as long as this kind of iron tire is slowly forged to keep absorbing carbon content, it will definitely be a good knife in the end! It's just that it takes a long time! Blacksmith Li swallowed, as a professional blacksmith, he was also happy to see the hunt, if he was given a piece of this, he could also create a weapon of extremely high quality!

Two-thirds of the iron ore has been refined, and the eight wrought iron bars three inches wide and more than one meter long are really not much! But these are enough, no matter more, the nineteenth princess can't afford to pay that much!

Wait until the next day to open the furnace again, Zhu Xiaobao has some experience, and is more confident, this time using charcoal and coke, in order to increase the carbon content, smelting pig iron, the melting point of pig iron is much lower than that of pure iron, when the carbon content reaches 4.3%, the melting point is only 1146 degrees. So the time of the day was not much, and four pieces of pig iron were placed in front of me......

Zhu Xiaobao, Wu Lijia and Ying Xiuxiu were all lying on the ground, and they couldn't care about their image, they were sweating all over their bodies, and they kept fanning the wind with fans, and in the past two days, they sweated several catties!

waited until the fire died down, and then asked Ying Xiuxiu to invite the nineteenth princess and others. The nineteenth princess immediately rushed to the scene with Chief Martial Arts and those guards, and saw the twelve iron bars on the ground, Chief Martial Steward's heart was really shocked, this thing really let this little fat man get out, although he also believed in Zhu Xiaobao, but when the real pure iron and pig iron two completely different products were placed in front of him, it was another kind of amazement!

"Wu ...... How's it going, Boss? The nineteenth princess couldn't understand the quality of these things, so she could only ask anxiously. I've been busy for more than half a month, and now I should have a conclusion! Xia Zhen'er's heart is also very nervous!

"It's definitely stronger than the iron tires of Yueling Mountain, and it's not a little stronger! I really believe that this guy can help Yue'er build a good knife now! Chief Wu whispered to the nineteenth princess, but he couldn't help but be excited in his words!

"Hmmm! That's great! It seems that the fourteenth sister really gave us a chance! Xia Zhen'er also said with relief. Of course, no one else could hear the conversation between Chief Wu and the Nineteenth Princess, and Zhu Xiaobao was still lying there fanning! For a fat man like him, this kind of heat is really a bit uncomfortable!

"Xiuxiu! You stay here today to help Xiaobao get some water, wash clothes, and take the initiative to see if there is anything you want to help! Xia Zhen'er was ready to go back with Chief Wu at this time, and when she left, she deliberately left Ying Xiuxiu behind, and asked a female guard to stay and take care of a subordinate, this is definitely the first time since the opening of the Nineteenth Princess's Mansion! The nineteenth princess is still very observant! And Wu Lijia, who was on the side, immediately understood and followed the nineteenth princess and left quickly, she even gave up lunch today!

"Yes!" Ying Xiuxiu didn't think much about it, but she was quite happy to respond.

"Huh? That's not bad! Zhu Xiaobao also understood a little bit immediately, but he was very happy, everyone was gone, and it was not more convenient to get a little cheap! So he hurriedly shouted loudly: "Thank you, princess! Those three pieces of soap are my filial piety to the princess! ”

"Nasty little fat man!" When Xia Zhen'er heard this, she suddenly trembled slightly, and scolded secretly in her heart with great annoyance, this guy knew that the three little maids were going to grab the soap behind their backs, but now it has become him to honor himself! In this way, the favor he gave him became a transaction! Cunning little fat man!

The nineteenth princess and Chief Wu quickly returned to the study, and Xia Zhen'er couldn't hide her excitement and said, "Uncle Wu! Do you think it's possible for our plan to come true? ”

"Hmmm! He will have to wait until he has tempered the treasure knife before he can make a conclusion. But this person's material is already very outstanding! But also be careful, if this kind of person is targeted by other princes or princesses, it will be counterproductive! Not to mention that if it is used by others, it will be even more dangerous! Chief Wu still tried his best to keep calm and analyzed seriously.

"Yes! If this kind of person is discovered by other royal brothers! The consequences are unimaginable! The nineteenth princess also said a little apprehensively. Her current strength is definitely not enough to keep Zhu Xiaobao!

"That's right! And that Ji Zhichen can't be underestimated, this person is even more difficult to get, he is outside all day, it is not easy to control! Fortunately, although he is acting a little ridiculous and lustful now, it is easier to confuse others! Moreover, his relationship with Xiaobao is extraordinary. As long as we show enough sincerity, then our plan is likely to come true! Chief Wu immediately thought of Ji Zhichen, and then reminded Xia Zhen'er.

"I understand, I will also arrange a guard for Ji Zhihui so that he can feel our sincerity!" Xia Zhen'er nodded, and then said ruthlessly. To say this is to give away another female guard! But to whom!

The next day, the nineteenth princess did not urge Zhu Xiaobao to hurry up and start building weapons. Instead, it is to arrange for people to help Zhu Xiaobao build a house! And let Zhu Xiaobao choose his own place! As long as it's in the princess's mansion, he can choose!

Zhu Xiaobao pondered for a long time, and finally chose his residence near the river, with his back to the nursery! Not only is the scenery here good, but the river can be used to the fullest!

However, according to the design requirements of Zhu Xiaobao, the nineteenth princess was shocked, and this guy actually wanted to build a bedroom, a study, a large kitchen, and a bathroom and a large workshop. He wanted to do a lot of things now, so he had to have a huge studio. After all, this apartment is actually 200 square meters. That's the equivalent of the living area of ten female guards!

"Build as he says! Dead Xiaobao, I can't get something I'm satisfied with, see if I don't clean you up! Xia Zhen'er finally gritted her teeth and said.

Originally, Zhu Xiaobao also wanted Xia Zhener to help him customize a batch of ceramic pieces pasted in the bathroom, which were used as ceramic tiles! was rejected by Xia Zhen'er! The little treasures had no choice but to give up! I really won't enjoy it!

Fortunately, Zhu Xiaobao also knows each other better, and he began to build a treasure knife the next day! However, he is an absolute novice in this regard, so he can only recruit Blacksmith Li again, and build while learning.

The first thing to do is not to build weapons, but to use ordinary iron tires to build weapons first, in fact, to learn the craft of iron......
