The existence of the crossbow also has its important significance, the value of the crossbow lies in its range, penetration and accuracy, the same is the crossbow of individual long-range weapons, its effective range is nearly half farther than the bow, it can penetrate two layers of iron armor, because the crossbow as long as the string is fixed can concentrate on aiming, unlike the bow to pull the bow and aim at the same time, the initial velocity of the crossbow is much higher than the bow, the accuracy is also higher than the bow, the effective shooting distance of the individual crossbow can reach three hundred meters, and the effective shooting distance of the bow is only two hundred meters.

Moreover, the main combat object of the Tang Dynasty is the nomads, and most of the enemies encountered are cavalry, and although there are a lot of cavalry in the Tang Dynasty, the main force of the war is still the infantry.

Although in recent years, the production of crossbows has made great progress under the expertise of the craftsmen of the Tang Dynasty Wuyan, and a number of high-tech processes have been adopted, but the rate of fire is still lower than that of the bow, but it has increased nearly twice the time compared to before, and about three arrows can be put into a crossbow, and after the use of the new three-stage shooting skills, the lethality and coverage of the crossbow have gradually become the main long-range strike means at present, and new weights and measures have been adopted to standardize the flow of operations. The production of crossbow machines has greatly increased the production capacity, but the materials of the crossbow arms still limit the scale of crossbow production.

I used to wander around the military-themed website back then, so I knew that mild steel could be used to make most of the structures of crossbows, so I had an in-depth discussion with the old craftsmen of the Martial Arts Research Institute, and finally tried my best to get these old men to agree to trial produce a batch of finished products. Of course, it's all made according to standardized work.

---------------------------------------------------- Datang Ministry of Industry will be the supervisor of the wrought iron smelted before the far far soft steel, moreover, these two are mostly used as weapons accessories, with the steel filling method to make weapons, but now the steel production has increased significantly, the supply of soft steel is in excess of demand, as the director of the Martial Arts Research Institute, for the steelmaking business of Datang I paid my own capital to reward, at this time, I am really sorry for myself not to use the waste and use my house as an experiment to get some profits, so my skyscraper can have reinforced concrete.

Without this thing, would I dare to build a skyscraper? Even if it is built, I don't dare to station, unless I am not afraid of death, you know, in ancient high-rise buildings, in order to reduce the load-bearing, mostly wood and stone, and my building, the overall use of masonry structure, at least in the fire surname can be higher than other Tang buildings, however, the weight is its injury, fortunately, with reinforced concrete, high-rise buildings are not in the dream. Because I was worried that the building materials would not be up to standard, I also deliberately cast twelve reinforced concrete columns on the structure of each building, except for the two in the middle of the building, and the rest were supported on the exterior wall. I'm not a master of design, according to my opinion, the more good things, the safer, but it is precisely because of this that I am afraid that the strongest building in Datang is my Datang Twin Towers.

After three days, I finally got the sample, and after assembling the various structures under the guidance of the old craftsman, a perfect steel crossbow was finally presented to me.

Beautiful, really very beautiful, the streamlined crossbow arm is made of hardwood to reduce weight, and the crossbow is made of soft steel multi-layer lamination, which strengthens the elastic power of the crossbow, in the sun, the crossbow looks so bright, the curved streamline looks so pleasing to the eye, and the crossbow machine is also made of steel, and the overall weight is about eight to ten catties.

After using the pulley-type push-pull structure on the top to wind, he aimed at the arrow target 200 meters away, and pulled the trigger, only to feel that the crossbow shook slightly, and the arrow target 200 meters away snapped, and the grass clippings exploded, and the red heart seemed to have been blown open with a big hole. The crossbow arrow seemed to penetrate the straw arrow target nearly half a foot thick, and immediately someone ran over to check it, and only after more than ten steps did he see the crossbow arrow inserted diagonally into the earth.

Do I still need to try? I only tried firing three arrows, and together with the ecstatic Zhong Hua, I broke down a pair of steel crossbows, asked the old craftsman on the side, and then put the components of the two steel crossbows into the wooden box together, and then carried more than 20 crossbow arrows in the wooden box and rushed towards Chang'an.

He Zhonghua walked into the main hall and presented the wooden box containing the steel crossbow to Uncle Li, and said excitedly: "Your Majesty, Chen Fang Jun presents the newly made crossbow of the Martial Arts Research Institute to Your Majesty. ”

"A new crossbow?" Uncle Li didn't quite understand, after all, Datang's crossbows were diverse, the largest car crossbow, as small as the hand crossbow, all kinds of crossbows were very complete, and there was no need to bother to make new inventions and creations. Well, that's probably what Uncle Lee thought.

"I said virtuous son-in-law, Zhong Qing, what are you doing...... You have also said that our Datang's crossbow is the most advanced, why do you want to go to a new system? Uncle Li took the wooden box that Zhao Kun took from me, opened it, and couldn't help but sigh lightly.

Uncle Li took out the soft steel piece of the longest crossbow, and said with a strong hand: "This is soft steel!" ”

"It's mild steel, it's made of mild steel, and it's used to assemble a crossbow." I approached and gestured for the installation.

Uncle Li's eyes lit up, his sword eyebrows were lightly raised, he reached into the wooden box, fiddled with the utensils inside, and his expression began to look serious. "Oh? You mean, can you install? Can the parts of these two crossbows be disassembled at will? Any redistribution of their parts and then a combination? "Uncle Li is really a smart person, and he grasped the key at once.

I nodded: "The little son-in-law learned from the old craftsman for a while, this thing is very simple. "I reached into the wooden box, picked up the parts, and began to assemble it, for when I was a child, I used to disassemble and put back the alarm clock at home, dismantle my cousin's model ship and model airplane, and then mix the porridge into a paste and stick it back, and finally suffered a good beating and repeated teachings, it was very easy for me.

----------------------------------------------------Besides, the parts are just that, very simple, it doesn't take much effort, a pair of steel crossbows were put in front of Uncle Li after I put the crossbow strings, but Uncle Li's eyelids didn't jump: "Go on, and put this pair on again." ”

glanced at Uncle Li, his expression was very serious, just pretend, anyway, it was just a practice to show his skills in front of the emperor, it was still rare to have a chance.

When the two sets of steel crossbows were placed in front of Uncle Li, Uncle Li's expression finally changed, he picked up one of the pairs, tried the crossbow string, and then took aim, and I quickly presented the crossbow arrows as well. Uncle Li carried the crossbow, pinched the crossbow arrow and walked out of the hall, standing outside the door, someone on the side had already brought the arrow target over, placed a hundred meters away, one arrow, two arrows, three arrows, after Uncle Li shot the sixth crossbow arrow, he changed to another steel crossbow, and aimed and shot in the same posture until this arrow target was shot to sparse pieces, and there was no crossbow arrow supply in my hand.

Uncle Li didn't speak, and although his expression was very excited, I could see that he was also worried, and beckoned to me and Zhong Hua, and returned to the hall to sit down.

After sitting down, Uncle Li's first words were: "Good things, really good things!" How long did it take to make it? ”

"It took two months, because it was the first trial production, so the first month was to design and standardize the size and weight of various parts, and it took about a month to make the finished product, and if it was mass-produced, I am afraid that it would be completed in about 10 days. Today, the steel mill of our Martial Arts Research Institute produces nearly 50,000 catties of steel per month, and the materials are sufficient, and according to the production capacity of the Martial Arts Research Institute and the use of assembly line operations, it can produce about 1,000 sets of crossbows a month. "Zhong Hua's behavior is very normal, although now he is just an official from the fifth grade, but since he is my deputy as a resident official of the Martial Arts Research Institute, he has dealt with Uncle Li a lot, so that now he is not as frightened as he used to be.

"A thousand?" Uncle Li pursed his lips, and his sword eyebrows finally stretched: "Okay, okay, but I have made a great achievement, which is to use steel as a crossbow, so that it will not be deformed due to the weather, and there is no need for so many various materials, and more importantly, I just saw your son-in-law's work, and the parts between the two sets of crossbows can be replaced, so that my Datang can greatly save an expense." Uncle Li sighed, and it could be seen that this was Uncle Li's way of expressing happiness.

Uncle Lee was overjoyed and rewarded all the incumbents who participated in the crossbow reform.

In addition, Uncle Li beckoned me to stay. Squatting opposite Uncle Li, looking at this old man with a very twinkling eye, what did he want to do?

"Virtuous son-in-law, sit down first, the old man is trying to ask you about something, well, it's not a big deal, but someone came to the old man to sue you." Uncle Li grinned, and a cold light flashed on the snowy big teeth.
