"Get up and move bricks!!" Yuwen Wen shouted, and then woke up, and looked around to find that he was lying in the shade of a tree, while Yuwen Fifteen was beside him, holding a big pu fan, looking at him in a daze.

Yu Wenwen then remembered that he was taking a nap, these days \ he urged people to build windmills on the spot, and he became a contractor foreman into the play too deeply, so he never forgot to let people get up and move bricks, sat up, and he looked at the windmill not far away.

Windmill, is a new project on Yuwenwen, the style is a reference to the world-famous Dutch windmill, he is not brain-dead but after careful consideration of the measures, Xiyang County is located on the Yangtze River, belongs to the hilly area, it is said that it is not a tuyere, but the wind is not small.

He carefully investigated, according to the people's recollections, the boundary of Xiyang County, especially the wind by the river and the lake, does blow often, but to say that it is big, it is impossible to say how big, since there is a wind is easy to do, so it is inevitable to use the wind.

Bazhou hills, ponds, few land, sparsely populated, many places have to extinguish snails before you can rest assured to invest in manpower reclamation, but it takes time, now to promote productivity can only rely on the power of nature, water conservancy facilities are not completed, before the waterwheel is not good, large-scale promotion, and animal power is not enough, so he decided to try to use wind power.

The people have lived here for generations, and it is impossible to say what the wind density is in the four seasons of the year, or which month is stronger, but the general impression is that the wind is stronger in winter and spring, and less wind in summer and autumn.

Considering that in the future, this place doesn't seem to have heard of anything tall like wind power generation, so the wind resources are also average, but the strong gusts of wind can indeed be felt by the riverside, so Yuwenwen decided to build one after thinking about it for a few nights to try the effect.

However, the first one to jump out against is Yang Ji, this one said that from ancient times to the present (now for Yang Ji is the Ming Chongzhen period), windmills are basically vertical shaft type, the structure is simple, the cost is quite low, now a horizontal shaft type is really unheard of.

Yu Wenwen didn't talk nonsense, "This is the windmill used by Hongyi, are you not convinced?" "Choking Yang Ji can't be argued, the Hongyi cannon was a sharp weapon in the late Ming Dynasty. In Yang Ji's opinion, Hongyi's windmill is about, maybe, probably, and should be reliable, so he honestly designed it according to Yuwenwen's idea.

No one's money is blown by the wind, so Yu Wenwen must act cautiously. As he always did, he first built a small-scale wooden windmill model in his workshop by the Ba River. After streamlining the structure, a full-size timber windmill was built.

After several days of running and learning from the lessons learned, a masonry windmill was built outside the city of Ba River, which, like the original Dutch windmill, had a canopy mounted on rollers that could rotate 360 degrees to adapt to the wind.

Outside Xiyang City, there is a wheel kiln brick factory built more than a year ago, and there is no shortage of wood, so the construction of the windmill is very smooth, today is the official operation of the day, the windmill tower is nearly ten meters high, the diameter of the wind wing is as long as fifteen meters, together with the workshop next to it, the cost is 1,000 yuan, and it is a medium-level house in Anlu City.

The reason why it is so expensive is because everything is done for the first time. In order to ensure safety, the redundancy is very high, and there are two sets of machinery driven by windmills in the workshop: stone grinding and pestle hammering of rice.

Stone mill can grind rice and wheat, rice is to husk the rice, this is a very practical thing, after this autumn harvest, the rice harvested here in Bahe City can be processed by a windmill workshop, after a year of operation, if it is cost-effective, then build a few more to liberate manpower.

The wooden windmill is still in the workshop by the Santai River, and Yu Wenwen has transformed its end into a pumping machine to test the pumping and drainage capacity, and if he can, he plans to use the power of the windmill to combine the progress of water conservancy repair and snail extinguishing to reclaim the middle and lower reaches of the Santai River into fertile land.

However, God doesn't give face today, Yuwen Wen came to the windmill workshop on the edge of Bahe City in a hurry to prepare for the 'ribbon cutting', but there was no wind, and he waited for a morning without even a little wind.

Then he fell asleep. However, after I woke up, there was still no wind, and when I looked up at the trees, I saw that the leaves were motionless and there was a wind blowing.

"Lord Lang. It's nothing, the windmill tower can also be changed to a watchtower, anyway, the money won't be spent in vain. Yuwen Wu'an said with a smile, and he hurriedly comforted him when he saw Lord Lang Yuwen Wen looking listless.

Yang Ji walked out of the workshop and came to him and said that it seems that there is no wind today, it is better to come again tomorrow, this 'architectural expert' in order to turn Yuwenwen's windmill into a real thing is also painstakingly designed and instructed the craftsmen to build it on the spot, and now it is a little disappointing to see that the windmill can't turn up without wind.

"You pull your face and do nothing, and you don't need to pay for it!" Yu Wenwen began to complain, but Yang Ji smiled when he heard the words.

Previously, he was responsible for guiding the rice transplanting method, and he was so busy that he finally survived, and the rice planting method that he vigorously promoted was carried out smoothly in the paddy fields outside Bahe City and the official fields outside Xiyang City.

"Envoy, is Hongyi really using this kind of windmill?" Yang Ji asked, only he and Yuwenwen knew what Hongyi was these years, so they were not afraid of others hearing the clues.

The so-called Hongyi, the Ming Dynasty's name for the Hongmao Holland, this is of course the tone of the Heavenly Dynasty and the Kingdom of Heaven and the Kingdom of Contempt for the Barbarians of the Quartet, but the Hongyi cannon in the other party's hand is not a joke, a cannon erodes for dozens of miles, it is the obscenity of the literati, but this is really a sharp weapon, Hongyi is good at equipment, so Yuwen Wen said that the windmill is used by Hongyi, and Yang Ji has nothing to say.

"Really, it's more real than pearls, but it has to be windy" Yu Wenwen didn't have the heart to say, the disadvantage of the windmill is, of course, to rely on the wind, if there is no wind, no matter how sharp it is, it is useless.

The traditional vertical shaft windmill in the Central Plains, of course, he knows, there are many advantages, but to make it bigger, it is a little troublesome, whether it is a vertical shaft or a horizontal shaft windmill, their efficiency is not high, so we must find a way to increase the wing \ sail to increase the length and increase the wind area, the larger the size, then the efficiency of the vertical shaft windmill is lower than that of the horizontal shaft windmill, and the shortcomings are becoming more and more obvious.

Looking at the immobile cross wind wings on the tower, he smiled bitterly in his heart: Negative energy, this is it, the day before yesterday, I went to the barracks for a day and watched the two thousand recruits being trained and screamed, and I felt how beautiful the world was

Just as the wind suddenly rose, Yuwen Wen was stunned at first, and then looked at the cross wind wing again, but did not move. I thought that this was the end of the day, but then a strong wind blew, and the cross wings began to rotate slowly.

"Let's go. Check it out! With that, he walked to the workshop under the windmill. When I got inside, I saw that the two sets of equipment had begun to run slowly, and as the wind outside increased, their speed gradually increased.

First of all, the stone mill, on which the rice for demonstration is placed has begun to be crushed by the stone mill that keeps circling, and the pestle hammer on the other side of the rice is also like a woodpecker.

Everything is running normally, Chen Wudi and the others who came in a hurry were quite surprised to see this scene, they didn't expect that the ability of this windmill was good, but the concept still couldn't be changed for a while.

Wouldn't it be better to push stone mills with water wheels everywhere, of course, some rivers have low water levels in winter, but if there are livestock, it is also good.

It's not that they question Yu Wenwen's decision, they just think that relying on the wind that comes and goes without a trace and comes and goes, and there is always no bottom for the stone mill or the rice, and it took a thousand times to build such a thing, and only Yu Wenwen can afford it.

Yu Wenwen didn't care about everyone's doubts. Of course, the use of water power is a priority, but if it is to be promoted, it will have to wait for the water conservancy facilities on the boundary of Xiyang County to be repaired, as long as it can save manpower and animal power, he will try it.

The windmill workshop is a new thing, he assigned a full-time staff to the workshop to be responsible for testing, commissioning, maintenance, the operation cost, effective operation time and other related matters to record, through a year of trial operation to use the actual data to evaluate whether it is cost-effective to build a windmill in Bazhou.

It's a cost of money, but as long as it's a problem that can be solved with money, it's not a problem......

Outside the city of Ba River, by the Ba River (water), an iron-making furnace stands on a high place, and many people on the sand field by the river are carrying a load of sand towards a building, and Yuwen Wen Wen and the generals are watching by the iron-making furnace.

River sand iron selection, helpless choice, but not without a target, because Ba Shui also has river sand iron selection in later generations. For Bazhou, which does not have a decent iron ore, this is timely rain.

Shovels, hoes, and pickaxes are needed to build water conservancy, and iron farming tools and curved ploughs are needed to plough fields. Iron sickles are also required for harvesting rice, and swords, guns, arrows, and armor are indispensable for fighting, which require a lot of iron, but it is not solved by money.

Huangzhou Prefecture governs the iron industry in Huangcheng, but the output is not high, so the products of the blacksmith shop are in short supply, Yuwenwen can get a few batches of iron tools back by 'brushing his face', but it is a little ugly too many times, after all, so many surrounding states and counties also need iron, so he has to find a way to solve it himself.

Ba water originates from the Dabie Mountains in the north, its river sand is rich in iron content, and the iron content is not low, Yuwenwen decided to use the method of river sand iron selection to collect iron ore as a raw material for iron smelting.

Relying on the opportunity to sell glass mirrors and glass products, he asked Wang Yue to collect magnets from merchants from all walks of life, natural magnets are naturally there, but how the merchants get them is the other party's business, anyway, there are magnets, there are glass mirrors, if you can't get them, then don't talk about it.

Finally got enough magnets, he began to design the river sand magnetic separation equipment, first the principle verification machine, then to the 1:1 structural model, then the prototype type, after running, debugging, and modifying countless times, finally there was a usable animal power-driven river sand magnetic separation equipment.

It's just usable, even with the iron-making furnace that has been built for a long time and relied on the 'introduction of talents', the daily output of iron-making is now pitifully less than that of the iron-making furnace of a serious mine, but it can be regarded as a problem.

"Envoy, relying on this river sand to select iron to refine, over time, it is also a tower of sand." Yang Ji looked at the iron-making furnace and the busy figure on the battlefield and sighed, he admired Yu Wenwen's whimsy more and more.

"That's right, gather sand into a tower, gather armpits into fur."

Shi Wansui looked at the iron-making furnace from the sidelines and agreed, when he heard that the iron should be selected in the river sand, he couldn't believe it at all, because it was hard to imagine how much iron sand could be selected in these river sands, maybe there was, but how much iron could be smelted was a problem.

When the sand selection equipment was running for the first time, Shi Wansui and other soldiers who were free came to watch, and saw a basket of river sand with water falling down from the funnel-shaped entrance, flowing down the wooden trough, and I didn't know what kind of magic power it was, and there was really black sand separated from the river sand.

Tossing for a few days, saving a basket of sand that is said to be iron sand, everyone reached out and took some and put it in the palm of their hands to see, just looking at it, of course, they couldn't see the fame, and finally when these black sand were thrown into the iron-making furnace and turned into molten iron and flowed out, they suddenly realized: This is okay!

The yield is not high, but everyone's expectations are high, because sand is inexhaustible everywhere in the river, and it is convenient to take sand by the river, which accumulates over time, but it is a lot, and now it is indeed a lot.

"How many arrows are there now?" Yu Wenwen asked, and then he added, "How many arrows are made of river sand and iron?" ”

"A hundred thousand arrows." Fifth Brother Chen replied, the quality of the iron trained by these river sand is still unstable, and it is a little brittle to make knives, but it is suitable to be used to make arrowheads.

The arrow shaft is made of bamboo, the fish bladder is boiled glue, the arrow feather is to find the mountain people to buy pheasants and pluck the feathers, these things are not lacking except for the lack of iron, now there is iron naturally can be made, the average cost of an arrow is not low to nearly 70 Wen, and it costs 7,000 yuan to calculate 100,000 arrows.

This is just the current price, when the cost of river sand iron selection and iron smelting will come down, the cost of arrows will also be reduced, the fish are all obtained by their own fishing, when eating or making dried fish, there are a lot of fish bladders, bamboo is everywhere, as for the arrow feathers, it is really not good, chicken feathers and duck feathers are OK, the key is iron.

"100,000 arrows, it's so many," Yuwen Wen muttered to himself, 7,000 is a lot, but for him, it is worth it, to do business, you have to invest in it to have output, 100,000 arrows can be counted as enough for 2,500 archers with a pot of 20 arrows plus a spare pot for each archer.

Taking it out to grab land, food, and women is much more cost-effective than buying jewelry with 7,000 yuan!

The iron used to make arrows can be used to create sophisticated armor and weapons, and the amount of iron produced will increase as the proficiency of iron selection in the river sand increases, and the production of scythes, hoes and other agricultural tools can ensure the progress of the autumn harvest and the construction of water conservancy facilities.

"Soldiers, are you all ready?" He asked.

"Ready!" Everyone replied, after resting for so long, it should be time to do their duty, and Yuwen envoy Jun's military salary can't be white-collar Besides, everyone is still waiting for meritorious service awards.

Yuwen Wen nodded when he heard this, he looked at the teams outside the military camp in the distance who were running armed cross-country and smiled: "Ploughing war, not only ploughing, but also fighting." ”

The busy farming season has passed, and in a blink of an eye, it is the season of human warfare (to be continued. )
