When he felt out of breath, not only the emperor had already been waiting here, but even the palm print eunuchs of the War Bureau and the eunuchs of the Admiral Armory had arrived, but someone had already told the emperor what had just happened. Wanli couldn't see any expression on his face, but said lightly: "All the things you want have been brought, and the craftsmen are inside!" Let's get that thing out first, don't worry about other things! ”

What does the emperor's words seem to imply? But he didn't have time to think about it, the eunuch of the Palm Seal of the War Bureau looked at him with disdain, he really couldn't believe that a thousand households who had never read a book could create such a sophisticated thing? However, the ambassador of the Ordnance Bureau of the Ministry of Industry looked at Lao Zhu hopefully, this thing they have not studied, a group of craftsmen have been working day and night, but they have never made a whole reason, even if there is no sufficient funding allocated above, but they have been persistent, and now there is finally someone to guide them!

Zhu Yidao stopped speaking, bowed to Wanli, turned around and walked into the workshop of the Ordnance Bureau. This workshop is really big enough, and I don't know how many craftsmen are busy, some are trying to make firearms, and some are pouring molten iron in molds...... Originally, it was possible to separate, but for the sake of convenience, at the strong request of the craftsmen, a large house was built, so that whatever materials needed could be quickly obtained. Next to the workshop is a warehouse full of all kinds of needed and discarded materials, which are taken to the boiler for incineration. However, from time to time, you can see the eunuchs of the East Factory of the Inner Court guarding, which is also to prevent safety accidents, in fact, the East Factory does not have to supervise the Arms Bureau of the Ministry of Industry, but because the War Bureau often has a lot of contact with it, and firearms cannot be manufactured and possessed by the people, so the Master of Ceremonies supervised the Weapons Bureau during the Yongle period. Of course, it is still subordinate to the Ministry of Industry Supervision and Manufacturing Department.

To Lao Zhu's surprise, all the craftsmen relied on their own skilled craftsmanship, but there were no equipment similar to standardized operations, could it be that those sophisticated firearms came from these people? The ambassador of the Ordnance Bureau on the side said proudly that all the firearms of the Ming Dynasty were made by their Ordnance Bureau, because of the huge number, they had to recruit craftsmen with the ability and conditions across the country, and the workshop was also expanded again and again, and the current workshop was built during the Jiajing period, and there are three in the back!

The eunuch of the Palm Seal of the War Bureau snorted coldly, and said, Your Weapons Bureau dares to say big things, is it possible that our Inner Court War Bureau is all eating dry food? It's all for the emperor, it's better to be careful when you speak! The ambassador of the Ordnance Bureau's face suddenly turned red: "Your War Bureau can be made, but your quality!" The Franco cannon that was built exploded after a few hundred rounds was blown, and there are still many craftsmen dead in the workshop! The cavalry Franc machine sent to General Li Chengliang cannot be used at all! How else would he have returned? Let's let the emperor come up and judge! ”

Seeing that the two were about to quarrel, Lao Zhu hurriedly persuaded that the War Bureau was also doing things for the emperor and the court, who could guarantee that there would be absolutely no problem with the artillery he made? As long as everyone does their duty, of course the emperor and his old man will understand! The eunuch of the Palm Seal of the War Bureau has only now seen his face improve a little, he has long heard that this Zhu Qianhu is not ordinary, and the relationship with his godfather Wei Gonggong who is in the ceremonial supervisor is very mysterious, and it is indeed worthy of his name, so the speech is different!

Chen Zenian, the ambassador of the Ordnance Bureau, spit on the ground hatefully, thinking angrily in his heart, your inner court has never been concerned about silver, who can compare with you? The annual allocation of expenses, the Eighth Bureau of the Inner Court is always full, not to mention the Supervision Division, the poor Ministry of Industry can't even send it, how to talk about manufacturing research costs? The craftsmen haven't received their money for months!

He took Lao Zhu to the side of several old craftsmen, and pointed to one of them: "His name is Bi Fei, and he is the pillar of our place!" It was him back then, with a few young men who pondered how to fly day and night, but they always failed to succeed. Zhu Yidao was very embarrassed to say this, where did he know what kind of tricks? It's just a coincidence, besides, I don't know how many I did at that time, and there were only a few that could fly, and they were basically destroyed when they landed!

"Lord Chen, you are really killing the juniors when you say that! Although the younger generation is a little higher, when it comes to manufacturing these delicate things, there are still a few masters with rich experience! In front of them, don't mention the little cleverness of the juniors! Looking at these pioneers of scientific and technological progress in Chinese civilization, Lao Zhu was really ashamed in his heart, if it were not for them, how could firearms have developed so advanced? Without the countless artillery pieces they built, what would the Ming Dynasty do to resist foreign enemies? For these old craftsmen, in his heart, all of them are priceless!

However, his heartfelt words made Chen Zenian, who was nearly sixty years old, very comfortable, this young man was not like those people in the inner court, shouting at these old guys, but respectful, looking at his appearance does not look like a fake, rare! How many young people are willing to learn this kind of craft these days? Seeing that he is not very old, he is already a fifth-grade military attaché, but he has such respect for himself as a ninth-grade ambassador of the Ordnance Bureau, Chen Zenian only feels that all these years of hard work have not been in vain!

Immediately afterwards, Zhu Yidao explained in detail the production principle and production method of the original delta wing, and several old men were a little contemptuous at first, but later, their eyes became bigger and bigger, and their expressions became more and more excited! The focus of this so-called simple version of the delta wing is that the material must be very light, and the fixation between the brackets must be very firm, and the layer of fabric covered on the bracket must also be very strong and breathable, and the texture is not easy to rot! There is also the angle of the bracket, which is very important. Most of the old men, including the principle, had never heard of it, but they understood it very well, and many things they didn't understand before suddenly became clear!

After all, they have too much experience in manufacturing, and they asked the key point in a few words. Zhu Yidao had to express it in the most simple words, but he also learned a lot of knowledge from it, and several people discussed it more and more enthusiastically. But in some specific places, Lao Zhu had a certain disagreement with the old guys, and the argument was not too intense, Bi Fei even sprayed saliva on his face, he didn't care about wiping it, and continued to debate with a few people. "Only practice is the only criterion for testing the truth!" Lao Zhu was also anxious, and stood up after yelling, he planned to use the facts to tell the old guys that what he said was correct.

But several people did not stand up with him, but looked at him. Chen Zenian, who was listening and nodding on the side, was also shocked by this classic sentence! Could it be that this kid still knows how to learn the mind? Not to mention him, even Wanli, who was visiting the workshop nearby, was stunned, and it seemed a little weird when he heard it suddenly, but the more he thought about it, the more flavorful it became! Isn't this similar to Wang Yangming's painstaking "unity of knowledge and action"? It's not that he doesn't know the study of mind, but he just thinks that this unity of knowledge and action is too unrealistic, how many people can do it? If you can do it, you're a saint. But Zhu Yidao rightly shouted it in the vernacular, and it had a strong demagogy.

The old men hadn't heard of Wang Yangming, they just thought it made too much sense! No longer hesitated at the moment, grabbed Lao Zhu and walked outside the workshop. In the north of the workshop, there are some open spaces, and there are many strange things piled up on the edge of the open space, Bi Fei said, these are the tools and materials used in the test that year, because the cost has been greatly reduced, and the experiment has gradually stopped, and has been placed here in the sun and rain. Zhu Yidao picked one up casually, and saw that the appearance looked like a scale, Bi Fei saw it and quickly asked him to handle it gently, saying that because of the wrong angle, countless experiments failed, but then only such an angle could fly smoothly, so they made a mold according to this angle, and then compared this mold for further experiments. It's just a pity that that's the end of it, and there is no further step! As he spoke, he sighed with emotion.

Lao Zhu thought about it, took out a piece of ** Baba paper from under the boxes stacked next to him, flattened it and folded it into a paper airplane, sighed at his head, and threw it out casually: "How did you experiment?" Is it like this? ”

The paper airplane deftly flew through the air and finally landed smoothly a few feet away. Zhu Yidao shook his head, thinking that when he was young, the stacked paper airplanes didn't fly too far, but now I haven't played for many years, and the technology has dropped so low, and it only flies a few feet away!

But Bi Fei looked at this paper airplane in horror, never expecting that Zhu Qianhu would have such a means! A piece of paper can fly into the sky with just a fold! The expressions of the other old men were similar to his, this is really a god! Back then, a few of them tinkered with it, but they didn't come out for a reason, who knew that this Zhu Qianhu was just a small test, and he actually made this piece of paper fly!

"This ...... This...... What is the reason...... "Bi Fei can't even finish his words, isn't the Feitian in his dream like this?

"It's very simple, the weight of paper is extremely light, when the air flow passes under the wing, because the wing area is large enough and the speed is fast enough, it generates lift, but then there is no power, and the speed has to fall." Lao Zhu didn't know what to say, so he could only talk nonsense, in fact, it was indeed such a reason, but he didn't know how to express it in the most popular words.
