Speaking of steelmaking and ironmaking, Yang Yaozong felt a little ashamed, but fortunately, with the help of those masters who were familiar with steelmaking, Yang Yaozong's blast furnace steelmaking method, although things did not go very smoothly, but it was also perfectly solved, and also made Yang Yaozong realize what it means to be interlaced like a mountain. Pen, fun, pavilion www. biquge。 info

Originally, most people in this period used the stove-type iron-making method, that is, digging a large rectangular soil pit on the ground, laying bricks underneath, leaving the wind eye, and erecting the crucible made of crucible soil in the pit, loading coal around it, loading the ore into the crucible, and then igniting the fire to make iron. After the iron ore is melted, the ore powder is added, and the steel is constantly stirred, so that the steel obtained is not only conducive to processing and forging, but also quite good.

The first time Yang Yaozong saw this steelmaking method, he felt that the production efficiency was too low, he only simply remembered blast furnace steelmaking, so he studied blast furnace ironmaking with some old ironmaking masters.

Because of the limitations of many factors such as fire transmission and convenient addition of raw materials, the blast furnace is not very high, only one or two meters. At first, it is easy to use a good blast furnace to make iron, you only need to fill the raw materials in advance, and then ignite and wait for the molten iron to flow out of the lower mouth, and the amount of iron ore filled is also more than that of the stove type, so that the iron smelted will be more than the stove type. Most of the iron that can be smelted is white iron. This iron is hard, not easy to forge, and brittle, and is not at all useful for making weapons, let alone artillery.

Although Yang Yaozong knew that white iron could also be forged through annealing, not to mention the troublesome process, so that the efficiency of iron production alone was not as good as that of underground stove ironmaking. Fortunately, after repeated research and experiments, Yang Yaozong and those old iron-making masters directly added an appropriate amount of toner when making iron, and finally the hard work paid off, and finally smelted steel suitable for forging.

As for the white iron produced before, Yang Yaozong couldn't bear to waste it, so he ordered the arsenal to process all these white iron into kitchen utensils and farm tools, and distribute them to the people of Zhangye for free. For a time, the people of Zhangye were replaced with brand-new agricultural and kitchen tools.

At this time, when Zhangye was in ruins, Yang Yaozong's small favor made the people of Zhangye very grateful, and its weight increased a lot in the hearts of the people. This is also in line with the old saying that it is better to give charcoal in the snow than icing on the cake.

When Ah Yi asked Yang Yaozong if he could produce artillery, Yang Yaozong remembered something, although he knew that it might be inconvenient to ask, but he still asked: "Ah Yi, remember that when you were at Yanmen Pass, you launched two cannons, did King Qin provide them to you or did you make them yourself?" ”

Speaking of this, Ayi pouted and said: "Those two cannons were indeed provided to us by King Qin, and we pulled them back piecemeal and then assembled them, but they are also easy to use." However, the craftsmanship and drawings used to make the cannon provided by King Qin have been changed in many places, and you Great Zhou people are cunning. ”

Yang Yaozong was also quite surprised when he heard Ayi's words, he didn't expect that King Qin was not completely anxious for quick success and quick profit, and he was not out of proportion on some key issues, but he was worthy of being the prince of the Great Zhou.

Ha Xin's obsessive retreat also gave Yang Yaozong time to breathe and develop. He didn't know how to make artillery, so he could only rely on those masters who had experience in munitions manufacturing to study it, and he only occasionally put forward some of his own opinions.

Regarding the manufacture of cannonballs, many veteran craftsmen who fiddle with gunpowder know, this does not need to worry about Yang Yaozong, Yang Yaozong just told them to pay attention to safety, and build the place where the cannonballs are studied and stored in a very remote place in Zhangye, and send heavy troops to guard it strictly.

Yang Yaozong went there every day for a while, not because he was curious, but mainly because he was thinking about using earthenware or earthenware as containers to create some land mines. Prepare to set up a minefield on the left and right of Zhangye official road to prevent the Hu people such as the Barge Horse Department from watching Zhangye.

Because of the management of Liu Liu in public security, and the sound of the economy, although Yang Yaozong is also busy, his mind is to concentrate on doing research in the military industry, what is the current technology to create that is simply whimsical, but the achievements in developing and manufacturing some land thunder and earth fire guns for a time are also significant.

"Nine Cakes!"

"Eat!"

"Bar! Sister, you can't eat your nine cakes! Dismantle that set of vices as soon as possible, if you want to hang up, let's think of another way! Yin Ruxin took the wooden plaque engraved with nine small round cakes very calmly and elegantly, and put it together with the three wooden plaques of nine cakes that had fallen on his own card, and said with a smile.

Ayi glanced at Yin Ruxin, but just snorted softly, showing a nonchalant look.

It was Mahjong that several women played together, and it was Yang Yaozong who made the pattern and then found a carpenter to do it, and then he taught several women how to play mahjong. Speaking of playing mahjong or Ayi and Yin Ruxin have more talent in this area, at the beginning Yang Yaozong also thought that he was happy to show off his skills in playing mahjong, a few rounds of play, Ayi and Yin Ruxin not only mastered the skills of playing mahjong, that is, to remember the cards and guess what other people will play what cards are guessed eight or nine are not far from ten.

In addition to mahjong, Yang Yaozong also made military flags, checkers and a deck of playing cards made of bamboo chips for several women. Compared with these playthings, several women still prefer mahjong more. often get together to play mahjong, and Yang Yaozong has to sigh, "national quintessence" is "national quintessence"! Its appeal is not comparable to that of ordinary playthings.

With these playthings, the mood of several women is obviously much better, and the relationship between them has also increased a lot. This is also the purpose of Yang Yaozong's making these playthings.

"My lord, you're back, Mrs. Qi Niang, come and play with a few ladies, it's time for the maid to arrange and prepare dinner." Thew stood up and said.

Yang Yaozong sat beside Mu Qinghan with a smile, and at this time it was Mu Qinghan's turn to touch the card, so he went up and touched a card, carefully rubbed the wooden card with his thumb, and sensed that it was a useless card, so he played it casually. smiled: "Qi Niang, you can go play for a while." Always accompany me every day, this card playing skill is a lot behind, don't let them bully you in the future. ”

looked at Yin Ruyun, who was sitting next to Yin Ruxin, and said, "Yun'er! You're getting lazy and lazy, but you always like to watch them play mahjong. If you have nothing to do, you have to go out and walk around more, after all, it will be produced in less than half a month. ”

Yin Ruyun has never been a person who likes to join in the fun, Xu is a pregnant relationship, but the temperament has changed a little, people are not only affinity, but also prefer to watch Yin Ruxin and them play mahjong. Although she also plays mahjong rules, she still prefers to watch from the sidelines rather than play it herself.

Yin Ruyun nodded slightly.

Mu Qinghan felt a little embarrassed because Yang Yaozong sat beside her so casually and helped her play mahjong, and in order to alleviate her shame, she said softly: "Sister Ruxin's fetal position is very correct, you can rest assured." And Wen Po has also been invited, and has arranged to live in the inner room. ”

Yang Yaozong looked at Mu Qinghan very gently, and then touched a card and smiled: "Hu! Qinghan! Collect money! (To be continued.) )
