As soon as he entered the room, Wang Ke's eyes were immediately attracted by the several weapons placed on the 'manipulation' platform, which were completely comparable to the mortars he had seen in later generations.

Wang Ke hurriedly stepped forward, his hand trembling and reaching for the mortar. Seeing Wang Ke like this, Li Ke asked in surprise on the side, "Brother Wang, what's wrong with you?" How does it look like this? ”

Wang Ke couldn't hide the 'agitation' in his heart, turned his head to Li Ke and asked, "When did you make it?" Where are the shells? ”

Li Ke hurriedly pointed to the wooden box in the corner of the wall, Wang Ke walked over and opened the box, took out two from it, and looked at it, which was no different from the pattern he had drawn before.

On the '' platform, Wang Ke looked at it carefully again, and said to Li Ke: "Call a craftsman to come in and let him tell him what's wrong." ”

Li Ke shouted a few times, and saw two workers in their forties walking in. At first glance, one of them was not from the Central Plains, but looked like he had come from the Western Regions.

Wang Ke is a little strange, this is the most secret place in the Tang Dynasty, how can there be people from the Western Regions here?

Wang Ke looked at Li Ke with a suspicious and 'confused' eye, Li Ke understood what Wang Ke meant, and explained in a low voice: "This person has been growing up in my Tang Dynasty, and has been smelting with his father since he was a child. ”

Wang Ke glanced at the person, and also asked Li Ke in a low voice, "Have you investigated?" Reliable or unreliable! ”

Li Ke nodded and said, "It's been investigated." My family died a few years ago, and I have a son who is a soldier in my Tang Army, and he is the only one in the family. Let him live in it now, and he can't just go out. ”

Wang Ke was a little relieved at this time, and said to the two workers: "What is the problem (computer reading .1 6 k . c n), you can talk about it first." ”

The man from the Western Regions was stunned for a moment, turned his head to look at the person who came in with him, and the man hurriedly whispered a few words in the ear of the person from the Western Regions.

This talent from the Western Regions said to Wang Ke: "My lord, that's the case, if the barrel we make now is made of steel alone, it won't take long for it to explode." Later, we added a layer of copper-based alloy to it, so that although the barrel felt like two layers, the wall of the pipe was much thinner and much lighter. ”

Wang Ke pulled over a cannon, looked at it carefully, and as he said, it was made of steel from the outside, but the inner chamber could clearly be seen to be made of copper and other metals.

Wang Ke knew that the barrel they made in this way reduced the brittleness of steel due to the special "property" of copper, and it could withstand long-term repeated "shooting" in use, and in this way, it could also make large artillery.

Wang Ke glanced at the two craftsmen with appreciation, and asked, "This is very good, so what else do you not understand?" ”

The two craftsmen looked at each other, and it was the Western Regions man who spoke: "The problem now is not the cannon, but the problem of the cannonballs. ”

Wang Ke picked up the cannonball again and looked at it, but didn't find any problems, and asked puzzledly, "What's the problem?" Doesn't it look like nothing? ”

Li Ke spoke at this time: "Brother Wang, this is not clear, or go to the experimental field and shoot a few shells, and you will know everything." ”

Wang Ke thought for a while, this is indeed a good idea, and now standing here and talking for a long time is not as intuitive as firing a few shells on the experimental field.

So he and Li Ke took these two workers to the experimental field, and the two workers quickly installed the gun carriage with their hands and feet, and adjusted the height up and down.

Now Wang Ke was a little surprised, he understood that there was no thread yet, how did they do this up and down adjustment?

Wang Ke stepped forward with curiosity to take a look, not to mention, although there were no threads, but these workers could think of making several feet of the gun carriage retractable, making grooves on the two sides, and after adjusting the height, using pins (computer reading .1 6 k. c n) so that the gun mount could be easily put away while marching.

At this time, Wang Ke also began to be impressed by the imagination of these workers, and couldn't help but extend his thumbs to the two workers to express his admiration.

The worker put the shell into the barrel, lit the fuse, and saw the shell fly out of the barrel. But when it fell to the ground, there was no explosion of the shell.

Wang Ke ran over and picked up the shell from the ground, and judging from the parts of the shell body that were sticking to the soil, he knew that the shell was not a bullet on the ground, so the pressure-fired fuse was not touched at all, so it became a dud.

Li Ke took the cannonball from Wang Ke's hand and said slowly: "Brother Wang, I am in a hurry to find you, I just want you to come and see this, and now that it is like this, I don't dare to report it to me, let alone ask my father to come and see the test shooting." ”

Wang Ke stood there, his mind had long been caught in the question of this cannonball, where was it? What needs to be done? What Li Ke said was deaf to him, and there was no reaction at all.

After thinking about it for a long time, Wang Ke didn't figure out a clue, and took the cannonball from Li Ke's hand again, and looked at it over and over again in his hand.

Finally, Wang Ke found out that something was wrong. At first glance, there is nothing wrong with this shell, but if you look closely, there are many problems.

First of all, the pressure fuse was not done right, the fuse was supposed to protrude, and the shell I saw just now was not equipped with a fuse, so I didn't care. Now that they have put the fuse on, it is almost as flat as the warhead.

One of the most important reasons is that the tail of this shell, after being 'shot' out of the chamber, should have rotated and flew forward, but now they made the tail fin and the body of the projectile together, forming a whole, so that the tail of the shell failed to play a balancing role during the flight, and often made the shell hit the ground at the moment, and it was not guaranteed that the pressure fuse hit the ground first.

Wang Ke hurriedly called the two workers to his side and explained to them in detail the problems he had discovered.

After listening to Wang Ke's words, the worker asked blankly: "How can this tail be made to rotate?" ”

Wang Ke was stunned for a moment, this appearance improvement is not difficult, but to make it spin, you must have a bearing, when I was thinking about making this kind of weapon, I didn't think about it so carefully, and now there is a problem, I think about this problem, it's really a little late.

But they have already reached this level, and it is impossible not to continue to do it, so I had to pull two workers, squatting on the ground and talking again.

It was easy to explain the entire structure clearly, and Wang Ke saw a trace of embarrassment on the faces of the two workers.

Wang Ke understood that they were considering that the steel balls in the bearings were not easy to do, but Wang Ke had no choice, he only knew this principle, and he couldn't actually 'operate' himself, so he had to pat the two of them on the shoulder and said: "There are two Lao, this problem can't be solved, and this weapon can't be perfected well." If you want this weapon to succeed, you have to solve this problem. ”

After a long silence, the two workers finally nodded and said, "Let's try again, and do everything we can to make it!" ”

Wang Ke hurriedly gave his eyes a 'color' and asked him to say something.

Li Ke understood what Wang Ke meant, this was to make himself a promise to the two workers what he would do after they figured out a way to solve the matter.

Li Ke hurriedly stepped forward and said, "You just have to do it." If you do it well, Your Highness will take credit for you, if you don't do it well, what responsibility will it take you! ”

The two hurriedly saluted Li Ke and said, "Your Highness, please rest assured, the villain will definitely do his best!" ”

Li Ke said words of encouragement again, saying that the two of them were enthusiastic, and immediately packed up their things and wanted to go back and start working.
