Zhu Youxiao was suddenly stunned, he has always talked about interests between countries, but in fact, isn't it the same between people? If you enhance the national strength of the Ming Dynasty and let the ministers also get benefits, then of course the ministers will support their own ideas.

He jumped up, kissed Zhang Yan and Duan Ying on the cheeks and said: "The ancients said that if there is a good wife in the family, all disasters will not happen, and I will not be bullied." Two good wives solved a big problem for me. ”

The two girls bowed their heads shyly, this emperor is good at everything, but he is a little out of shape, in front of people, the sky is white, it's true.

Zhu Youxiao said: "Wait for the two of you to go and see Wang Wan, don't wait for me at night, I won't eat in the palace." ”

He called Wei Zhongxian and went directly to the Weapons Bureau. Sun Yuanhua and the three welcomed him in. Zhu Youxiao asked: "How about the output of plate armor?" ”

Sun Yuanhua said: "Back to Your Majesty, now you can make fifty pieces a day, and a total of more than two thousand pieces have been made." ”

Zhu Youxiao nodded: "Bi Qing, how is the progress of the new firecracker?" ”

Bi Maokang replied: "Back to Your Majesty, the rifled firearm has been initially formed, and according to Your Majesty, both the range and accuracy have improved, and it is easier to reload." Your Majesty's wisdom is as vast as a sea of smoke, every time you think about it, you have to thank God for your mercy, and I can't wait to worship Your Majesty as a teacher, and I want to see the way of heaven and ask for ......."

Zhu Youxiao interrupted him embarrassedly: "Bi Qing, I just got it by chance, and I don't deserve to be praised by you so much." Now as long as he sees Zhu Youxiao, Bi Maokang chatters, and he actually wants to worship Zhu Youxiao as a teacher and learn the art of the instrument, so that Zhu Youxiao, who has stolen the achievements of future generations, is very embarrassed.

He hurriedly asked again, "Bi Qing, how many of these rifled firearms have been made?" ”

Bi Maokang was very unhappy that his apprenticeship plan had failed again, but he had no choice but to reply: "Now there are only about 500 finished products, and although the rifling production has the help of machinery, the speed is still very slow. ”

Zhu Youxiao soothed: "It's already good." Bi Qing, I have a few more ideas, and I can just ask the three of you. ”

The three of them didn't even dare to say, Bi Maokang said: "Your Majesty's learning, such as the art of immortals, how can you use the word "ask for advice" in front of Weichen and others, isn't it shameful to wait?" The minister felt that it would be ...... if the minister was to learn from His Majesty."

Zhu Youxiao hurriedly interrupted: "Bi Qing, I won't mention this again, but we can refer to it together, my first thought is, can you load ammunition from behind?" ”

Mao Yuanyi stepped forward and said, "Your Majesty, there are examples of rear charges in the Franc cannon, but the effect is not very good. ”

Zhu Youxiao said: "Artillery and guns are the same, but there are some differences, because to increase the airtightness, oh, it means that the gas does not leak out, and the guns should be easier than the artillery, especially after we pull the rifling." ”

Bi Maokang had also seen the rear-mounted Franc cannon, so he temporarily let go of the apprenticeship, thought about it carefully, and said: "Indeed, our new type of firecracker can make the air leakage very small, and the air leakage of the gun is more troublesome. ”

Sun Yuanhua also said: "The rear installation is easier than the front installation, and the front installation must be dressed standing, and the rear installation can also be installed lying down." ”

Zhu Youxiao said: "The three Aiqing said very reasonably, if the firearm is used in the afterload, the speed will be much faster and more convenient, on the battlefield, if the speed is increased by one second, it may be a life." ”

The three of them all nodded, the front-loading guns they made now, reloading and firing, skilled test guns can only shoot four times a minute, and soldiers on the battlefield are definitely below this speed, three times is considered good. If it is rear-equipped, as long as the soldier can fire four times a minute, it will be a full five seconds more.

Zhu Youxiao continued: "The same is true for guns, and the guns can also try to improve the leakage of the Franc cannon. The second thing is actually mentioned earlier, that is, when the gun is fired, the gun body will be subjected to a backward force, if we let the gun barrel shrink back and then return to the original after firing the gun, will this force be reduced, and the gun will be more stable. ”

Mao Yuanyi, who participated in the installation and reconstruction of the large-caliber guns on the Fu ship, said: "At that time, the ministers used springs to reduce recoil, and His Majesty said that if it was used on the barrel, it seemed that it could also have the same effect, and the aiming of the guns would not be affected. ”

Zhu Youxiao nodded, he didn't know how the artillery eliminated the recoil, but he once saw the barrel shrink back after the shell was fired out in the movie. What I can provide can only be an assumption, and as for how to do it, it depends on the people in the Arms Bureau to think about it.

He added, "The third thing is a new thing, Factory, bring it up." ”

Wei Zhongxian hurriedly took the small glass tube in his hand carefully. Zhu Youxiao took it, and Wei Zhongxian took the teapot and an empty teacup next to him.

Zhu Youxiao's hand was a sealed glass tube, he first filled the glass tube and the teacup with tea, then pressed the nozzle with his hand, turned it upside down and put it in the teacup, and released his fingers.

Everyone watched as the tea in the glass tube flowed out, and an empty tube appeared, but after a while, the tea no longer flowed out. The crowd didn't know why, and looked at the emperor, waiting for him to explain what it meant.

Zhu Youxiao said proudly: "Why doesn't this water come down completely? With that, he pulled the pipe away from the surface of the teacup, and all the water flowed out.

The three of them looked at the pipe, but still did not understand, so they looked at the emperor again. Zhu Youxiao waited for them to answer, and also looked at them, so the four of them started a game of staring at each other.

This was more embarrassing, and Zhu Youxiao had to ask again: "Three Aiqing, why doesn't this water flow down completely?" ”

Mao Yuanyi was young, so he spoke: "Your Majesty, because there is water in the cup." But then he figured out that it wasn't like that.

Sure enough, Zhu Youxiao pouted again, and Wei Zhongxian took out a glass tube with openings at both ends, inserted it directly into the teacup, and looked at him with a smile.

The three of them all fell into deep thought, and after a while, Bi Maokang said: "Your Majesty, this example seems to be somewhat similar to the bellows, close the air intake, and pump a few boxes hard, and the force used will become greater and greater. ”

Zhu Youxiao was overjoyed and said: "Bi Qing's words are reasonable, the two are actually the same principle, I believe that there is a kind of thing everywhere in our lives, I call it air." ”

In fact, the word air has appeared in ancient China, and there is such a sentence in Su Shi's "Treatise on Dragon and Tiger Lead and Mercury": "When the party is pranayama, it is rinsed and cooked, and it must be full of mouth and then swallowed." If it is not full, and it is left in the mouth, waiting for the next time, it is still sent to the dantian with air, and it is often raised with intention. ”

All kinds of requests, thank you for your support!
