Take the mall to Datang

Xin Liangchou trembled a little while holding the torch. According to Yuan Shan's description of the cannon, the cannon would make a loud noise and smell of gunpowder smoke after it was ignited. It was the first time that he, a scholar, took the initiative to do these things. What he did now was completely Contrary to the theory that a gentleman should not stand under a dangerous wall, Yuan Shan has already said that there is danger in testing guns, but Xin Liangchou insisted. In the end, he could only use a long stick to ignite the torch, at least it would be safer after a longer distance.

"Boom." A loud noise shocked everyone, especially those craftsmen. They never thought that the things they made in the past ten days would be so powerful.

On the other hand, Jiancheng and the master were much calmer. I don't know if people who have studied are courageous, but these few people are still quite courageous.

In an instant, a mess appeared in the woods more than 100 meters in front of the artillery, Xin Liangcho shouted excitedly: "We succeeded, we succeeded."

Yuan Shan looked at the lethality of the shotgun, and had to say that the conical diffuse coverage is still very deterrent.

"Xin Jiancheng is just the first test shooting, the test must be rigorous, let's continue." Yuan Shan said calmly.

"Yuan Zhengjian is right, I am too excited, let's start the second test now." Xin Liangchou said.

At this time, Yuan Shan saw that Xin Jiancheng's interest was simply fanatical, and then the second test began, checking the gunpowder and filling the gun body, adding projectiles, and then igniting.

"Bang!" There was a muffled sound, and the shells scattered tens of meters away from the gun body. The scattered projectiles were still smoking, and there were cracks in the barrel mouth.

"Yuanzhengjian, the cannon body is damaged and can no longer be used." The craftsman immediately ran over to check and said.

Xin Liangchou rushed up immediately, and said, "How could this happen? This is the second test and it failed."

"Song recorded things, recorded the test process and the appearance of the gun body, and asked someone to come over and analyze what went wrong." Yuan Shan said calmly.

Everyone gathered around and saw that the cracks in the muzzle were torn. Yuan Shan found that this was not because the quality of the iron was not good. If there was no flowering, it might be because the thickness of the gun barrel was not thick.

Perhaps more iron hoops should be added to the gun barrel, especially the muzzle should be made into three folds. The temperature dissipation is also a problem. The craftsmen also checked the inside of the gun barrel. After the gunpowder is ignited, it still needs to be cleaned. Otherwise, the barrel will affect the performance of the barrel.

A lot of data prove that this first large gun still needs to be improved. Under the current situation of backward technology, Yuanshan can only combine the data and ask the craftsmen to thicken the barrel. See, that's the only way to deal with it.

In addition, to be on the safe side, Yuanshan also added a new type of artillery, that is, the mortar. The short-body "mortar" predecessor of the mortar is easier to produce. Although the range is not far, it is a siege No matter what, the mortar can be fired successfully no matter what, this is a perfect preparation.

Soon the second cannon was completed. This new cannon also took half a month. The barrel was shortened a bit, but the thickness did increase a lot.

When building the cannon, Yuan Shan was not idle. He was also studying the ratio of gunpowder and was gradually adjusting it. He is a science student who understands these things theoretically. This time, the power of gunpowder has been slightly adjusted. .

A group of people came to the place for the first test again. This time the cannon looked a little thicker in appearance, but it did shrink in size, which was also for the convenience of production.

"Prepare to light the fire." Yuan Shan said directly.

This time it was still Xin Jiancheng who took the initiative to invite Ying. It was the first test firing. As soon as the sound sounded, the projectiles flew out of the barrel. This time, they were filled with solid bullets, which cost much less and were easy to make. Xin Liangchou was very calm this time, and immediately said: : "The first test, complete, apply for the second test."

Yuan Shan waved his hand to signal the test to continue, the craftsmen came to reload and then the second test firing started, Yuan Shan was actually very nervous, the chamber exploded in the second shot of the first test, it's no wonder he wasn't nervous.

"Boom." The gunpowder smoke filled the air, and everyone could clearly see the damage caused this time. It was not a mess, but a big tree happened to hit it directly, and the big tree was blown down immediately.

"The second test firing is complete." Xin Liangchou called.

"Check the condition of the gun barrel and conduct the third test firing." Yuan Shan said.

"Load the gunpowder and load the shotgun." Xin Liangchou said.

"Boom." The scattered projectiles blasted the woods in front of them into a mess.

"The third test was successful." Xin Liangchou said.

"Check the condition of the gun barrel and record the data." Yuan Shan said.

"Three test shots were successful, Yuan Jianzheng, shall we continue?" Zuo Qiu asked from the side.

"Pause the test firing, check the condition of the barrel, and record the damage after the projectile lands." Yuan Shan said.

"Yes." Zuoqiu said.

"Come here today, write a memorial to report the situation to His Majesty, and we will complete the task." Yuan Shan said.

In the East Palace, Li Shimin was holding the memorial just presented by the military inspector, looked at the message and shouted: "Okay, Yuan Shan really made the artillery."

The next day, it was still in the open space of the military weapons supervision and testing artillery. At this time, there were many people here, but Li Shimin was not present. The ones who came were Fang Xuanling and Du Ruhui, and the general Yuchi Jingde.

"Yuan Shan, is your thing really that powerful?" Yuchi Jingde asked suspiciously.

"Practice is the only criterion for verifying the truth. Now that everyone is ready, let's start today's experiment. However, I want to remind you that the gunfire is very loud. After ignition, it is recommended that everyone cover their ears." Yuan Shan said.

Yuchi Jingde was talking to Yuan Shan here, Fang Xuanling and Du Ruhui were touching the small cannon, and Xin Liangchou was explaining to them.

"Begin testing the cannon, please step back a little bit," Yuan Shan said.

Xin Liangchou, who likes to play with fire, still went up to Chen himself, holding a long ignition stick, and started to play with his cannon, the small cannon, triumphantly in front of many people.

"Boom." The gunpowder smoke filled the air, and a burst of white smoke rose from the whole cannon. Fang Xuanling and Du Ruhui had never seen this before, and thought something happened to the cannon.

Yuchi Jingde was fine, since he had seen the grenade, he still had some adaptability to these artillery.

This gun uses shotguns, which are not as powerful as solid bullets, but the effect of spreading out is still very scary. A hundred meters away from the artillery, it scattered all over. In order to show the power of the artillery, some bullets were placed on the target. grass man.

At this moment, all the straw people were carried over, and they were all covered with small projectiles.

Chapter 214 Gunpowder Supervisor

Several people were carefully checking the grass man's situation, Du Ruhui said in shock, "Yuan Shan, is this the power of artillery?"

Yuan Shan saw that it was only a small-scale damage, because the artillery that is only made now is no different from the large-scale firecrackers, except that the projectiles are scattered, and the spread of a large area is larger. The distance is not as good as that of a bow and arrow, but the deterrent effect is still there. very big.

Hearing Du Ruhui's question, Yuan Shan immediately explained: "Du Shangshu, this is just one of the least powerful types of artillery. The projectile is made of multiple projectiles, and its lethality is so-so. Covering infantry and dealing with cavalry will play a role." Certain effect."

"Yuan Shan, you said this cannon is the least powerful, so what is the most powerful?" Du Ruhui asked curiously.

"I'm not sure, it might easily destroy the city wall." Yuan Shan said.

"Well, we've seen this artillery now, and its range is a little less. It's hard to say how useful it will be to Tang's military. I want His Majesty to tell the truth." Du Ruhui said.

"Lao Dushang wrote it." Yuan Shan said.

"This thing is good, let me try it too." Yuchi Jingde took over the fire rod and reloaded the ammunition with the help of the craftsmen. Now he uses solid projectiles.

The "boom" solid projectile just hit a tree, directly causing a large gap in the tree body. The power was astonishing, but the distance did not exceed a hundred steps. Yuchi Jingde was very excited, and then clicked again. hair.

"Boom" made a short loud noise, and fired a projectile again.

It's just that this time I was unlucky, and didn't hit the tree, but fell to the ground in the distance, directly smashing a small hole.

This small artillery can have such an effect thanks to the improved gunpowder, which is more powerful but requires a high strength of the barrel. Yuan Shan saw that Yuchi Jingde was having a good time playing, so it will not work if this continues. The small cannon has not passed the limit test, if it suddenly exploded, it would be difficult for them to explain.

"General Yuchi, this artillery is just a sample, and the limit of continuous firing has not been tested yet, so let's stop first." Yuan Shan said.

"Haha, I fired it twice more on the spur of the moment, but the range of this artillery is still shorter than that of bows and arrows, and swinging this artillery on the battlefield will take up some soldiers, and the mobility and flexibility need to be further adapted." Yuchi Jingde said .

Yuchi Jingde was experienced in many battles, and he was aware of the problems in the use of this new weapon at the first time, and Yuan Shan also knew it. As for how to move the firearm, it still needs further research.
