In the Wuhan Institute of Technology, in front of Zhong Hua's desk, I checked the report handed over by Zhong Hua, and nodded as I looked at it: "Well, okay, our steel production has increased again. How many kilograms of mild steel can be produced this month and how much hard steel can it produce?"

"There are about 35,000 kilograms of soft steel, and about 20,000 kilograms of hard steel. But now the officials are worried about not enough pig iron. Otherwise, let's apply to the Ministry of Works?" Zhong Hua came over to me and said.

I smashed my mouth and shook my head: "No, at least not now. Although the output has increased, it is not a good achievement for Wuhan Research Institute. By the way, has that soft steel crossbow tool been made?"

"We are stepping up. We can make ten soft steel crossbows in one or two days. The output is small at present, so we can't use running water to make this thing. So, we just let a few experienced craftsmen try the production." Zhong Hua answered my question. Xuan Ji smiled and said, "I asked Master Hong Fu, no one believed that he could use steel to make crossbow tools. If the adults hadn't explained it personally, I'm afraid that those craftsmen would still not want to do it now."

"This has nothing to do with me. The most important thing is that we must know how to innovate, know how to use the wisdom of our predecessors to transform, and add our own ideas..." After I said a lot, I squeezed at Zhong Hua: "Mr. Zhong, the construction site here is still short of some soft steel, and it costs about 5,000 kilograms, you see..."

Zhong Hua didn't understand what I mean: "Even if you come here, just take it, and you will make the decision. The output of mild steel is so large now. It is really eye-catching, but its purpose is not obvious. In order to use mild steel, adults are willing to take risks. I really admire them."

"Well, hehe... Thank you for your kindness. Tomorrow, I will ask someone to withdraw money from my account. Although I am a tester, I cannot afford to pay a penny. After all, we cannot let down the trust of His Majesty." I nodded seriously and almost made a happy heart.

There are many high-rise buildings in the Tang Dynasty. The Yellow Crane Tower, Yueyang Tower, and the tower of Guangzhou Fan Temple that Li Xiaode told me were also about 30 meters high. In addition, the Wentian Pavilion, which Yuan Tiangang and others had built on the back mountain of Qingyang Temple last year, is said to be at least 50 meters after completion. Naturally, I cannot be left behind. Besides, as the head of the Tang Dynasty Wushu Research Institute, I did this to make my due contribution to finding a way to sell products, so why not do it?

Besides, I adopt an architectural style that is essentially different from them. Although it is still a classical Chinese architecture, the design concept I adopt is postmodernism. Well, I invented a new term.

Speaking of this, I was happy. Nowadays, the coal production in Datang is rising steadily. The invention of coal stoves has not only driven the industry of mining and selling coal, but more importantly, the steel production of Datang has also increased rapidly because I, yes, because I know what coke is.

Nowadays, there is a hydraulically driven piston bellows, and there is also coke needed for steelmaking. What else is there? There is nothing missing. With the innovation of the heavy money rewards, most of the craftsmen have been jealous and green in the field to find ways to innovate steelmaking technology. Thanks to the efforts of the Wuyan Institute and the joint efforts of the top and bottom, including the powerful creative enthusiasm inspired by the heavy rewards, after many improvements by these masters, now, not to mention the ground, the Wuyan Institute alone has established a steelmaking factory for steelmaking, which has nearly 50,000 kilograms of soft and hard steel released monthly. You should know that the Tang Dynasty used to produce only 100,000 kilograms of steel every year.

As for the steelmaking technology, Datang land used is the steel-frying method recorded since the Western Han Dynasty. The raw material for steel-frying is pig iron. The key point is to heat the pig iron to liquid or semi-liquid, and use blowing or sprinkling concentrate powder to oxidize silicon, manganese, and carbon, and reduce the carbon content to the composition range of steel and cooked iron. Most of the products of stir-frying steel are low-carbon steel and cooked iron, but if controlled well, medium-carbon steel and high-carbon steel can also be obtained.

The original low-carbon steel was not very useful in the eyes of the ancients. Making soft swords? Damn! There are not so many martial arts masters in the world. Using the popular steel filling method of the Tang Dynasty to make weapons can also consume so much soft steel. Then process it? Yes, but it will also consume a lot of fuel. Moreover, I am also a half-bottle water expert who has been mixed up on major military-themed websites. I have heard of the production of soft steel crossbow arms. The crossbow tools and bow tools of the Tang Dynasty are the most complex single-soldier long-range weapons in the world that I have seen. It can be said that according to the current production procedures and techniques of the Tang Dynasty, the complicated procedures even exceed the production process of artillery. The production of the long-range weapons of the Tang Dynasty was based on the "Kaogong Ji" in the early Warring States Period as a model for materials selection and production.

The first is the six materials that "take six materials for the bow" are: dried zhe, mulberry, orange, papaya, jing, bamboo, etc., horned cow horns, tendons, glue deer, horse, ox, rat, fish, rhinoceros, silk and lacquer. A clear selection standard is stipulated for each material. The production process of bows is really very particular. The bow is made in winter, soaked in spring, and treated in summer. In autumn, the three are combined with silk, glue and paint to make a bow body. After winter, the bow body is placed in the bow box to determine its shape. Then install the bow strings in the spring next year to check. Just like the treasure carving bow given to Xue Rengui, the old craftsman said, the time taken for the good bow alone is three years. The production period of ordinary bows is at least one year.

The Three Pure Ones are above, and it took only nine years for us to build an atomic bomb in China in later generations. Although the investment is incomparable to the future generations, in terms of the production period, this is just a conventional long-range weapon, which requires so much effort. You can imagine how much waste of human and financial resources this has caused.

There were six types of bows in the Zhou Dynasty. Their effects were different. In the late Warring States Period, the status of bows was affected by the appearance of crossbows, so the names were not as diverse as crossbows. Most of the time they were only called "bows". The bows in the Tang Dynasty were divided into four types: longbows, horn bows, slightly bows and lattice bows. Longbows were used for infantry battles, horn bows were used for cavalry battles, slight bows and lattice bows were bows for hunting and imperial guards.

However, what is even more frightening is the function of the crossbow. The material selection of crossbows is more stringent, and the selection surface is very narrow. For example, the crossbow body must be made of hard mountain mulberry wood, the crossbow tip is made of sandalwood, and the crossbow machine must be made of metal, and its strings are also mixed-shaped twisted ropes. Although a crossbow is made about one year, due to the narrow material selection surface and the advantages of the bow, these two long-range weapons can coexist at the same time.

At present, the use rate of bows and crossbows are about three to two. The main reason is that the structure of the bow is much simpler than that of crossbows. It is easy to make a large amount of materials on the spot. It is light in weight and has a range of not as fast as a crossbow, but it has a fast shooting speed. A well-trained archer can shoot as fast as six to ten times faster than a crossbow. In other words, a archer can shoot six to ten times faster than a crossbow during the period when the crossbows shoot the second crossbow, and can shoot at any time. The crossbow is weaker than a bow in this regard. However, the advantage of a crossbow is that the crossbows used is much shorter than the long arrows used in the bow. The individual crossbows used by soldiers of the Tang Dynasty are about thirty centimeters long, and the bow is nearly one meter long, because the flying speed of the crossbows is faster, and there is no need for a long arrow like a bow to fly stably. The consumption materials alone are nearly twice as different.

Another point is that crossbows are more conducive to aiming than bows, with high hit rate, long range and high lethality. They are very powerful long-range weapons in ancient times. Moreover, in the Tang Dynasty's army, most of them were temporarily recruited by farmers, and the use and training time of bows often fail to meet the requirements, because the shooting skills of bows are too complicated. A good shooter needs to go through thousands or even tens of thousands of shots before he can become a qualified shooter. But crossbows are different. As long as you can follow the instructions and use the crossbow to standardize the target, you will most likely hit it if you hit the board machine after you hit it.

Due to its limited mechanism of action, the hit rate is very poor. The bow relies almost entirely on the archer's own experience for aiming. Although the arrow has a tail feather as a stable rudder, the arrow has a large area of ​​wind and a slow initial speed. Generally, it takes three to four seconds to hit a target two hundred meters away from the slack string, while the synthetic bow and single bow are even worse. Therefore, all the combat bows used by the Tang army are compound bows.

In order to increase the initial velocity of the arrow as much as possible, the elasticity of the bow can be continuously increased. As a result, the person must use a lot of strength to open the bow. During this force, the arm will inevitably tremble greatly. Therefore, the accuracy of the bow and arrow becomes worse, and the diffused method has to be used to increase the chance of hitting. Secondly, the damage of the arrow is small, which is incomparable to the damage of the crossbow.
