In the history of mankind, any invention is the crystallization of the wisdom of countless people, even if the inventor is just a flash of inspiration, but for this little inspiration, I don't know how many people's efforts have been spent, after a long evolution, years of experience accumulation.

The invention of the blower, in the history of the earth, is a leap in the way of metallurgy, and there are many twists and turns, and the improvement of the blower almost spans thousands of years.

However, now Qiu Yan knows the principle and function, and what is missing is only the specific design, which can relatively save a lot of effort, and it will cost a lot of manpower and material resources to change others, but the many incense thoughts of the gods and goddesses are equivalent to millions of people thinking together, and they are naturally fast.

Before Hu Qi and Dai Guo came back, several different blower designs had already taken shape in Qiu Yan's mind.

Then, after a long while, Hu Qi and Dai Guofang returned.

Hu Qi was holding a few furs in his hands, and Dai Guo was carrying a few short logs, the broken parts were not neat, and the handprints could be faintly seen, which were obviously brought over after being interrupted by his bank.

After glancing at the timber and estimating the quantity, Qiu Yan nodded and said, "The amount of this timber is not enough to make a water row, but it depends on the situation, and Liu Xin's shop may not be near the water." Then he led the two back to town.

The riot in the town had subsided, and the old woman was not young, she had been crying for a while, almost tired, and was helped back, but Liu Xin was still in place, looking left and right, with an anxious expression.

Next to Liu Xin, there are several big men standing, tall and strong, at first glance they are not as good as Hu Qi and Dai Guo, but among ordinary people, they can be regarded as strong.

Seeing Qiu Yan and the three of them coming, Liu Xin showed joy on his face and greeted him, followed by several other big men, one of whom was still whispering.

Although he deliberately lowered his voice. But in the ears of Qiu Yan and Hu Qi, it is still very clear, and it is clear that they are captured-

"Liu Xin, you have to think clearly, this person may be a liar. ”

"If our secret is revealed, it is likely to ruin the job!"

"The man went to your shop, be careful, the offerings must not be seen by them. ”

And as Liu Xin walked, he was also complaining in a low voice: "Uncle Li, Uncle Feng, when the previous person was collecting debts. I came to the door to ask for help, but you didn't help, when the Huozheng tablet broke, I asked you for help, and I still pushed three blocks and four, little nephew, I was forced to a dead end, even if this person is a liar, I have to give it a try!"

......

The conversation between these people was full of distrust of Qiu Yan. aroused Hu Qi and Dai Guo's dissatisfaction, and they wanted to come forward to theorize, but they were stopped by Qiu Yan.

Immediately after, Qiu Yan walked towards Liu Xin. After the two said a few words, Liu Xin led Qiu Yan towards the town, and Hu Qi and Dai Guo hurriedly followed.

As for the big men, they are also tightly embellished. looked at Qiu Yan and the three of them with a vigilant face, which made Hu Qi and Dai Guo unhappy, although they took refuge in the border to hide. But he still has the arrogance of a master, if Qiu Yan hadn't stopped it, he would have had an attack a long time ago.

A group of people walked along the small river in the town, then left the river and went deep into an alley.

Qiu Yan observed all the way, and when he saw that he was away from the river, he frowned slightly, knowing that he was going to change Jihua.

Soon, several people came to a shop, which was connected to a courtyard, and the name of "Liu's Blacksmith Shop" was written on the door, which was clear at a glance.

In front of the door, the old woman was talking with an old man in front of the door, and when she saw Liu Xin bringing a few people over, she immediately stepped forward to stop her, but then Liu Xin walked over and said a few words, and the old woman hesitated.

At this time, the old man next to him walked up and arched his hand to Qiu Yan and said, "This gentleman, the little old man is polite here." ”

"The old man is fine. Qiu Yan returned the salute and waited for the other party to speak.

"Mr. is polite, the little old man Yu Qing, for Xingtai Township, I heard that Mr. has the heart to help the mother and son of the Liu family, so I came to testify, and if I am offended, please also ask Mr. Haihan. ”

Qiu Yan said with a smile: "Where, Qiu took the liberty to come to the door, it is inevitable that he will be abrupt, the township is acting properly, and it is natural to come over." As he spoke, he looked at the old man in front of him.

The man looked to be not young, with a white beard and hair, but with a ruddy complexion and a satin dress, he was clearly a gentleman.

The local administration of Darui is divided into provinces, prefectures, and counties, and in addition to the army, all of which are appointed by the imperial court to officials and military positions, but under this, according to the law of organizing households and people, they are divided into townships, villages, communities, and villages to maintain social operation.

However, this division is not based on administrative institutions, and the imperial court does not send officials, and the township and Li Zheng are all elected by the righteous families of the households, and generally speaking, they are held by the first-class and second-class households, that is, the rural landlords.

Most of the villages and towns in Darui are composed of clans, which are relatively stable and closed, so the government is actively supporting, but after all, there is a lack of direct control, and there will inevitably be drawbacks, such as the villages and towns are of different sizes, some are too bloated, and there are many of them.

Qiu Yan had heard from Wen Anguo that the imperial court was brewing a "armor protection law", saying that it was to use administrative means to divide the number of households, divide the clans that were too large, increase the stability of the grassroots level, and reduce the cost of maintaining law and order.

Of course, these things are far away from him, so they just turn quickly in his mind and disappear.

After a short greeting, he followed Liu Xin into the shop.

"Sir, I don't know what you plan to do?" Liu Xin asked anxiously, he actually didn't know the bottom in his heart, just holding the idea of a dead horse being a live horse doctor, just now he had already noticed what Hu Qi and Dai Guo were holding, and seeing that the two did not follow in, he couldn't help but be a little anxious.

Qiu Yan waved his hand and said: "Don't worry, the sage said, 'go first, and then follow it', you can't mess up when you encounter things, you must observe first, know the specific changes, and then prescribe the right medicine." With that, he paced around the shop.

When Yu Qing heard this, his expression moved slightly, and he raised his hand to stop several men who were about to follow.

These people are also blacksmiths in the town, and they have a good relationship with Liu Xin's father, and this time Qiu Yan came forward, they were inevitably worried and afraid of leaking something.

Qiu Yan deliberately replied with the words of the sages, what he wanted was this effect, even among the people, the words of the sages were also very useful, they were the criterion of morality and behavior, and they could capture some thoughts and let him explore them.

The shop is divided into two parts, the outer room displays iron objects, and the back is an inner room, where the iron is struck, and there are two furnaces in the room, a crucible furnace in the center, and a blast furnace standing by the wall.

Looking around, Qiu Yan's gaze fell on a shrine in the corner.

The shrine was empty, and there was nothing missing from the shrine in front of it where the offerings were placed.

This observation took a lot of time, and even though the words of the sages could appease people's hearts, after all, they could not eliminate prejudice and hostility, so I listened to the discussion of a few big men from the outhouse.

"I've been watching this for a long time, is it okay?"

"If you can't do it, retreat as soon as possible. ”

"Yes, interlacing is like separating mountains, don't think that if you read a few books, you will be able to do everything. ”

......

These people did not deliberately lower their voices, obviously speaking to Qiu Yan.

Even Liu Xin was already shaken at this time, and he had the heart to remind him, but he didn't know how to speak.

"Okay, I guess I have an idea. At this time, Qiu Yan suddenly spoke, and without waiting for Liu Xin's reaction, he let Hu Qi and Dai Guo walk in, and then gave an order.

The two nodded frequently, and then followed the order, put the wood in their hands on the ground, and polished it with their palms.

"I thought that these two people were just the scholar's entourage and house slaves, but I didn't expect them to have such skills. ”

"Fortunately, I didn't say anything too out of line just now, otherwise it would be worse to anger these two. ”

Just when a few people were secretly rejoicing, Hu Qi and Dai Guo had polished a few things under Qiu Yan's guidance, and Qiu Yan borrowed needles and threads from Liu Xin's house to sew fur, and those hands flew up and down, extremely fast.

The three of them are all masters of life cultivation who have entered the refining of their souls, and their control of strength and limbs is meticulous, and some carpentry and needlework are naturally hand-to-hand, looking at the degree of proficiency, it seems to be a long time.

It didn't take long for several things to be made, and then several people were busy in the room.

Seeing this, others didn't dare to say much because of the force, but the expression on their faces was a little disapproving, obviously not optimistic.

In a few moments, a simple blower was erected.

Four booms are hung on the roof beam, used to pull and hold and fix the skin bag; there is a cross wood on the skin bag, the middle is fixed on the bag, the two ends are stretched, fixed on the left and right walls, there is a damper, a pull rod behind the bag, and there is a hole in front of the bag.

This kind of appearance makes the viewer scratch their heads and do not know its effect, even the hand-made Hu Qi and Dai Guo are confused.

But Qiu Yan did not explain, but asked Liu Xin for a copper pipe.

Holding the pipe, Qiu Yan twisted a few times, and then came to the crucible furnace in the center of the room.

The stove was not ignited, Qiu Yan bent down, let go of the perception, and instantly felt the structure of the stove clearly, then raised his hand, sent the copper pipe in his hand forward, and inserted it into the bottom of the stove seat in many exclamations!

"What is this doing, sir?"

At this moment, even Liu Xin couldn't help but come over and exclaim, implying reproach.

Qiu Yan waved his hand, did not answer, raised his hand and wiped it a few times at the socket, his fingers were hot, pinched the stove, and sealed the gap between the copper pipe and the soil. Then he pulled the brass pipe, and with a surge in his hand, he bent the brass pipe and attached the other end to the hole in the front of the skin.

The blower bag is thus connected to the crucible furnace.

After doing this, Qiu Yan glanced at Liu Xin and said loudly: "Open the furnace and make iron!"

At the same time, he calmed his mind and was on guard, his perception slowly let go, his eyes narrowed, and his heart was even more full of thoughts-

"Whether the mysteries of Heaven and Shinto can be gradually revealed depends on this temptation......" (To be continued......
