(Today's two chapters are some technical information, if you are not interested, don't read it, and thank you for the book "The Biography of the Founding of China", many of the technical information in this chapter are quoted from the book.)

In addition, thank you for your tips and opinions, I will choose at my discretion for your suggestions, thank you for inspiring me elsewhere, to be honest, I really haven't paid attention to this information before, and it will be reflected in the plot in the future. ）

Seeing that it was about to reach the end of the first month, the will that should have been issued to Xincheng a long time ago has been dragged by the ministers of the dynasty and the central family, even if it is as strong as Jia, the latter has to retreat in the face of the united family, and the will to the prince has been delayed for another month.

Fortunately, Sima Shu had already expected this, and just after the New Year, he was not idle and busy planning the Huangzhuang.

At present, water conservancy, roads, bridges and other projects in Huangzhuang have been regularized, and at the same time, another good news came that made Sima Shu almost jump up with joy. It turned out that the expedition team he secretly sent finally got the news that in the mountains near the new city, a coal mine and an iron mine were found.

This news made Sima Shu look forward to the ironworks and machinery factories for a long time, and finally put them on the road, and now he has found a "place to use" with his professional counterpart!

Xincheng County, although it is not a resource-rich area, but there are also a lot of mineral resources in the local area, especially coal resources are very rich, and other mines such as gold, iron, copper, coal, limestone mines, although not as much as coal, but also enough for Sima Shu to use in the early days.

After nearly a month of rushing work, the factory located outside the new city and by the Yishui has begun to take shape. Iron-making furnaces, forging rooms, equipment rooms, carpentry rooms, etc., were built and put into operation one by one.

Coupled with the craftsmen he recruited and his own technical support, the Xincheng Workshop began to produce iron and began to manufacture weapons and agricultural tools in batches.

As a college student in the 21st century, Sima Shu definitely doesn't look down on these clay furnace breaking tools, because in his eyes, steel is not made little by little, but smelted from one furnace to another. But he knew that he couldn't get any open-hearth and converter furnaces, so he could only make some improvements to the current iron-making furnace.

To make steel, you have to coke first, which is the foundation. As for how to refin, Sima Shu thought about it for a long time, but he only remembered seeing a report from a certain newspaper that disclosed the closure of a number of small coking plants. There is a paragraph about coking in the middle, which seems to be a reporter's trick, briefly describing the principle of coking coal refining.

Coking coal is isolated from air in a closed coke oven, heated at high temperatures, releasing moisture and adsorption gas, and then decomposing to produce coal gas and tar, leaving coke with carbon as the main body. He also briefly describes the "evil" method of coking in earthen ovens to criticize its bad impact on the environment.

But what is coke? Sima Shu didn't know. He had to make a clay furnace first, under the condition that the air is not isolated in the kiln, with the help of the ignition hole on the side wall of the kiln, the coking coal stacked in the kiln is ignited, and the coal is heated layer by layer by relying on the combustion heat of the coking coal itself;

The exhaust gas produced by the combustion of the coal and the large amount of unburned coal cracking products are then allowed to continue to burn through the fuse channel on the side wall of the kiln chamber and transfer part of the heat into the kiln.

Extend the coke maturity for 8~11 days, inject water from the artificial ignition hole, quench the coke from the cold furnace, and finish the work. However, Sima Shu was depressed, and found that this "coke" was like firepower, not like high-calorie coke, so he had to change to coal and refine it again.

In this way, the first step was finally completed by refining the coke with strong firepower.

In his spare time for cokemaking, Sima Shu directed the craftsmen to improve the iron-making furnace. If we can't do open-hearth and converter, let's build a small blast furnace.

The foundation of the blast furnace is built on the basis of the shaft furnace, but it is much taller and more complex. The stove was more than six feet high, surrounded by a wooden frame. The circumference is rounded, the upper small and the lower large are all sealed. There is a small opening on the top to feed the inlet, and there is also a conveyor belt made according to the water wheel to directly throw iron ore, coke and limestone into it.

There is an air inlet under the furnace, and the air fed in by this air inlet is not poured directly into it, but through a channel. In the middle of the tunnel there is a preheating chamber, which is heated by a coke compartment around it, so that the air fed into the furnace is also hot. The entrance to the air supply channel is a large windmill, and the powerful power is the same as the feeding conveyor belt, which is a water wheel driven by the river next to it.

The molten iron is released from a slightly higher taphole, and the remaining impurities and limestone in the iron ore are burned into slag and pulled out of the slag mouth. After smelting raw iron, the next step is to come in and forge hundreds of refining into steel.

Sima Shu, who studied machinery, knew that the carbon content was more than 2% pig iron, below o.4% was wrought iron, and between o.4-2% was steel, but how to grasp this percentage in this environment?

After thinking about it, Sima Shu suddenly remembered that when he read an extracurricular book in middle school, he mentioned several steel-making methods in "Tiangong Kaiwu", so he immediately started to try it.

He first set up a short wrought iron blast furnace next to the pig iron blast furnace, and as soon as the pig iron came out, it was directly fed into the wrought iron blast furnace through a heating and holding channel. The "gas" from the top of the pig iron blast furnace is fed from the bottom of the wrought iron furnace and the heated air, and then ignited and heated, and the molten pig iron sent in is smelted again and directly smelted mature iron.

Sima Shu knew that if a suitable catalyst was added, the carbon content in the iron could be controlled and the steel could be directly smelted. But Sima Shu didn't have this ability yet, because it involved chemistry, which was much more complicated than the mechanical and simple smelting disciplines that Sima Shu was familiar with.

Let's be a down-to-earth person. According to the introduction in "Heavenly Creation", Sima Shu beat the wrought iron into thin slices, such as a finger wide and one and a half inches long, clamped the pig iron with iron sheets, placed on it, and then covered the top layer with broken grass, coated the lower layer with mud, and then used a small coke oven to add a water wheel to blow the air. When the temperature reaches a certain point, the pig iron melts first, infiltrates into the wrought iron, and the two are fused together, and then taken out, hammered, re-refined, hammered again, and repeated several times until the steel is beaten.

In order to think about this knowledge that he had unintentionally read before, Sima Shu racked his brains, and even the "depths" of his memories of peeking at "The Heart of Shaox" in middle school were scavenged.

He and the craftsmen did experiments again and again, but fortunately, there were no accidents and no serious casualties. However, Sima Shu left a rule that any experimentation and innovation in the workshop would be left behind, and the craftsmen would leave detailed records and drawings, no longer exploring based on experience.

However, in other aspects, Sima Shu is somewhat handy. In the ironworks, he built a tall and spacious one, and then put wheels on the roof to make it easy for the craftsmen to move heavy objects, which made them more efficient. In addition to using water power to make blowers and conveyor belts, Sima Shu also used water power to make forging hammers, simple grinding wheels, lathes and other tools, which made the craftsmen admire.

With the foundation of materials laid, Sima Shu was finally able to guide the craftsmen to build all kinds of weapons. After all, your materials are not good, no matter how beautiful the lines are, the weapon is also a tofu scum project. For a promising young man who often goes to the weapons forum to spit, the eighteen weapons are very familiar, and even the very famous Mingguang Jia knows a thing or two.

In order to unify and accurately measure, Sima Shu developed a set of weights and measures and completely refined them. According to the set he was familiar with, Sima Shu turned four feet into one meter (similar to the current one meter, and one foot at that time = o.245 meters), and then the bottom of the meter was decimeter, centimeter, and millimeter according to the decimal system.

To create a one-cubic-meter container, it can be divided into 1ooo cubic decimeters, and one cubic decimeter is also a liter, which can be divided into 1ooo cubic millimeters, and one cubic centimeter is one milliliter. Filling a cubic decimeter with "pure water" weighs one kilogram or one kilogram. It can be divided into 100 grams, 10 grams and grams. The force of a kilogram of weight suspended vertically in the air is a jun. These are all metric systems, and the number used in the factory is the metric system.

Sima Shu also stipulated that one mile is 500 meters and one zhang is 2.5 meters, one foot is o.25 meters, one inch is o.25 decimeters, one is divided into o.25 centimeters, two catties are one kilogram, one tael is 50 grams, one stone is 1ooooo milliliters, one bucket is 5ooo milliliters, one liter is 5oooo milliliters, and one is 5o milliliters, and one is 5o milliliters.

Finally, two sets of rulers, containers, and weights were made from gold, silver, and copper alloys as metric and municipal standards.

With these foundations, Sima Shu drew the graphics one by one according to the appearance of those sharp weapons in his memory, so that the craftsmen could build them according to the drawings, and Sima Shu also set a rule: after the new weapons were made, they must invite veterans with rich combat experience and "countless kills" to try it, let them talk about the quality of the weapon, and then modify the final shape in combination with everyone's opinions. Originally, this weapon was for them.

The Pu knife based on the "Song Dynasty hand knife" (different from the Pu knife of later generations). The blade is arc and seventy-five centimeters long, with a thick-backed single-edged tip, sharp front and back oblique, and a short-handled gauntlet, this one-handed knife can be chopped and stabbed, and is specially equipped for infantry such as knife hands.

Based on the Qi family knife, the Yanling knife (different from the Yanling knife of later generations) is also called a waist knife. The curvature of the blade increases, the width of the blade decreases, the length of the knife is eighty centimeters, and the tip of the knife is not sharp but has a small arc and is extremely sharp. This type of knife was intended for crossbowmen and shieldmen, and was the most common configuration of infantry.

The long knife that was not very practical was discarded, and the horizontal knife of the Tang Dynasty was redesigned. The blade is one meter long, and the knife is similar to the Yanling knife, the only change is that not only the blade is long, but the handle is also 30 centimeters long. It is completely possible to carry the knife with both hands to be more ferocious, and the horizontal knife is equipped with personnel above the non-commissioned officer level of the team.

At present, Sima Shu lacks cavalry, so Mo Dao still wants it, but according to the requirements of Mo Dao hands, it has been slightly improved, plus the material technology has kept up, and it is more sharp and ferocious, and it is equipped for the future Mo Dao team.

The Divine Arm Crossbow is to be made. Sima Shu made great improvements to the existing crossbow, not only changing the bow arm to a simple compound type of topwood and horns (which is different from the standard compound bow making), but also thickening and becoming more powerful. Then add a device in front of the crossbow, as long as the soldier points the crossbow downward, he can step on a cover in front of the crossbow with his foot, and then he can wind it with both hands.

Sima Shu was not satisfied, he used the crossbow eccentric wheel device he saw on the Internet before, anyway, there are simple lathes, complex components can't be made, and it is not difficult to get a wooden eccentric pulley.

Such a powerful crossbow can shoot 450 meters, which is much more powerful than ordinary muskets. At that time, a test shot of 50 meters and two layers of heavy armor immediately frightened Zu Ti, Sima Ya, Xu Chao and others who came to ask for "new weapons".

There was also the longbow, which Sima Shu borrowed from the craftsmanship of the English longbow that he knew. Start by making a special bracket made of hardwood, with one end digging a groove vertically to hold the bow back, and the other end trying to be fixed vertically to the ground. The sides are carved from top to bottom at an equal distance of 8-1o chord grooves every four centimeters, of which the first chord groove is twenty centimeters away from the bracket head.

Then choose a good piece of topwood to make a bow, tie the two ends with a rope in the relaxed state of the bow back, put the center of the bow back on the groove of the bracket, and slowly pull the string evenly and forcefully to hang it in the first string groove, and the bow back is slightly bent. At this time, it is necessary to carefully check whether the curve of the arch is smooth and even, mark the areas that are too stiff, relax the arch back, and trim and fine-tune until you are satisfied.

Then pull the rope apart, gradually increase the opening, hang the groove downward, and keep trimming the bow back until a satisfactory and uniform arc is formed. The opening of each three or four chord grooves can tighten the rope a little.

This process should not be rushed, especially before each increase in the opening, let the bow back "rest", a column of incense, so that the internal force can be released, so as not to damage the wood. Don't tighten too much each time, it's best to tighten two centimeters at a time. When a suitable standard full bow opening is reached, the bow is tamed.

Then, combined with the production process of the Chinese composite bow, the deer tendon or cow tendon is used to make tough filaments, which are tightly and orderly wound around the bow body, and then the leather glue boiled from cowhide, pig skin and other animal skins is coated with it, and finally lacquered and air-dried. The bowstring is made of deer tendons, which are soaked in fish gelatin (fish tissue, especially the inner skin of the palate and fish fat), then dried and wound around the bow horns, straightened, and reinforced with fish gelatin.

The longbow thus produced has a long moon shape, which is different from the usual mountain bow. The bow is one meter six high, and is paired with an eight-meter-long arrow.

Sima Shu tried it and felt that the strength was about the same as the British longbow that was more than 1.8 meters tall that he had played with before, but it was worse than the strength of the current standard refined Chinese compound bow. But it's easy to make! Ten skilled craftsmen can make thirty qualified longbows a day (a hobbyist can make a similar longbow a day).

The production of a qualified composite bow is very complicated, and under the current production process and existing material conditions, it can only be made for several months or even years, and can only be specially made for generals.

In terms of arrows, Sima Shu also used his brains, and the crossbow arrows of the divine arm were fifty centimeters of heavy wood, with an iron tail and an iron tail of the arrow; The longbow arrow is 80 centimeters, the goose feather or chicken feather tail arrow body is made of heavy and bullet taka wood, and at the moment of the loose string shot, it will be the same as the English longbow arrow, the arrow body will bounce up and bend slightly, and the bow arm will no longer touch, reducing friction.

The arrows of the arrows are all of the same standard format. The triangular spike is of equal length on each side, and the body is four centimeters long (all the way to the triangular spire), and the tip has a blood groove on each side. Cast in a mold with pig iron, the blade is carefully sharpened by a craftsman.

Other weapons were also "designed" by Sima Shu one by one, and in the end, he actually designed a cavalry saber based on the saber wielded by the Cossack cavalry in the movie memory.

Relying on these bright designs, Sima Shu was amazed by the craftsmen, and his heart that had been "crushed" in other places was restored.

With these sharp weapons, Sima Shu began to make changes to the equipment of his subordinate troops. He and several of his generals summed up the experience gained in the previous wars, and then summarized the characteristics of the current wars, and then Sima Shu determined the official establishment of the Donggong Guards according to his understanding of the Tang, Song, Ming and foreign ancient military establishments.

Take the team as the basic combat unit: a shidao, holding a small round shield with a simple sword, wearing infantry light armor (the armor is divided into front and back pieces of chest and vest, nailed iron armor, with a belt buckle on both shoulders, the two shoulders covered by the shawl to make animal skin pattern, the belt droops, there are two large knee skirts, and several rows of square leather armor are stacked on top of it. ）； The two shields were worn in infantry armor with tortoise shields, slender spears and goose swords, and they were in a team. The two archers were equipped with longbows and fifty arrows, and wore leather armor with a goose feather waist knife; The four Shi god arm crossbowmen with the god arm crossbow with thirty arrows, and with the goose feather waist knife and leather armor, a total of two teams. The rest of the standard-bearers, trumpeters and non-commissioned officers were all equipped with horizontal knives and chains, which were connected by iron chains and interlocked, forming a garment-shaped chain mail.

In this way, the organization went to the tun and then to the battalion, and each battalion formed a Mo knife team, and more than 100 people were selected, and brave warriors wore chain mail, equipped with horizontal knives, and a wild goose knife. At this point, the establishment of the East Palace Guard was finally perfected.

In just one month, Sima Shu first laid the foundation for the "industry" in Huangzhuang. The most important thing is that these craftsmen, under the influence and encouragement of Sima Shu, sparks of wisdom are popping up, and new and new ones are emerging in an endless stream. And under the generous remuneration, these craftsmen are almost crazy, especially after Sima Shu realized the division of labor assembly line in the armor room, bow and arrow room, and the equipment room, the craftsmen not only showed their skills more exquisite (of course, they only did the same for a long time, of course, they were exquisite), and they did more work and got more pay.

For a while, knives, guns, and armor were piled up, and strong crossbows and longbows were piled up in the warehouse. Soon, the newly recruited Donggong guards began to change their equipment according to the new formation.

However, due to the restrictions of raw material extraction, the production progress of the new city factory slowly slowed down, and began to move on to further technological innovation and creation. There are few people to open mines! Sima Shu was now a little impatient to take control of Xincheng.

On the other hand, Sima Shu finally made the most optimized and basic organization for his infantry army, which would later become famous all over the world. Later, although there were some changes, most of them were made on this basis.

After a busy month, Sima Shu laid a solid foundation for his future take-off.
