Sure enough, the few old men who came back to their senses were not generally confused about the professional terms Zhu Yidao said. Lao Zhu knew that they couldn't understand what he said, so he simply didn't say it, and started making the utensils on the field. It doesn't matter if he doesn't understand what he says, as long as he understands what he does! Seeing this, the old men hurriedly stepped forward to help, and forgot about the eunuchs who were watching the Palm Seal of the War Bureau behind them.

In Chen Zenian's heart, he originally had great doubts about Lao Zhu, no matter how humble his attitude was, he was just a master with low eyes, after all, he was too young, this kind of delicate work would definitely not be able to do it, and even if he did it, it would be useless. He only hopes that this Qianhu can do him a favor in his thinking and wake up. But he not only uttered those very flavorful words, but also did amazing things! The flying paper airplane has always been spinning and turning in his heart, how did Zhu Qianhu do it? This sentence reached his throat countless times, but he swallowed it back, because he knew that talents like Zhu Qianhu with unique skills are often family secrets, and they are passed on to men but not women, and they are passed on to their elders but not to their concubines. Even if you ask, how can you tell yourself?

But he really couldn't suppress the extreme curiosity in his heart! In the fierce struggle, Chen Zenian finally opened his mouth: "Zhu ...... Zhu Qianhu, this ...... This thing ...... I don't know how...... What do you call it? He really wanted to know what Lao Zhu called this flying thing, even if he just knew what it was called, he would be satisfied!

"Oh! Paper airplanes! Zhu Yidao, who was busy, replied without replying.

"Fly...... Plane?! Chen Zenian's eyes widened again.

"Yes, because it can fly, and it can do all sorts of things like a machine...... That's why it's called an airplane! "Now Lao Zhu doesn't know how to explain it, he can't talk about machines, right?

Chen Zenian nodded his head like a chicken pecking rice. Airplanes, image, very image! The eunuch of the Palm Seal of the War Bureau and the eunuch of the Admiral Armory behind him even scratched their heads, and they didn't figure out what the reason was that paper airplanes could fly in the sky. But facts speak louder than words, this piece of paper really flew after Zhu Qianhu's mysterious processing! How exactly did he do it?

Wanli couldn't believe his eyes either. This is the second time he has seen something that can fly, but didn't Zhu Yidao say what kind of delta wing it is called, what is the difference between it and this plane? Could he be doing anything else that can fly? Wanli keenly thought of the usefulness of this thing, if there were thousands of planes flying to the enemy's castle tower with gunpowder...... I want to know the result with my feet! He couldn't help but shudder.

Zhu Yidao has explained everything that can be explained, and how far he can go depends on the craftsmanship of several old craftsmen. When it comes to experience, he is far from being able to compare with these pioneers. At this time, he couldn't intervene, and could only watch a few old craftsmen skillfully operate, cutting the bamboo strips as thin as possible.

He suddenly remembered something, turned around and walked to Wanli's side, and said respectfully: "Your Majesty, the subordinates who should do what they should do have already been done, and please ask the emperor to agree to the requirements of his subordinates!" ”

"No problem!" Wanli replied to him very happily and directly, "During this time, you will be directly responsible for a few of them!" I just want the final result! There is only one sentence, the delta wing will be made in 10,000 years! ”

Lao Zhu wanted to laugh but held back, how did this sound so familiar! However, it did express Wanli's determination, and he knew how useful this thing would be on the battlefield in the future! He settled down and continued: "During this period of time, the workshop of the Ordnance Bureau of the Ministry of Industry Supervision and Construction must be protected by the Jingshi Health Office!" No one is allowed to enter without your decree, and those who violate the order will be beheaded! Everyone must be monitored, including family letters, before they can enter or leave! In particular, all craftsmen must be registered and registered, and entry and exit must be strictly controlled, and whether the delta wing is successful or not, it must be kept strictly confidential, otherwise the consequences will be unimaginable! ”

Wanli suddenly realized! Yes, such an important thing, if the leak is in the hands of foreign enemies, then Da Ming will really shoot himself in the foot! That's not going to work! He immediately issued an order, and asked his attendants to record it: "Urgently transfer the Ordnance Bureau of the Supervision Department of the Ministry of Guarding and Engineering of the Beijing Division, and any personnel entering and leaving must be strictly inspected, and if they do not obey the management, they will be given full authority to the Beijing Division, and they will be killed!" Chin this! ”

With this layer of talismans, even if the prince of Naping wants to trouble him, he has to weigh the weight, between the delta wing and the prince of peace, Wanli's choice is naturally obvious. It is said that the next day, Prince Ping was severely reprimanded by Wanli and sent to Li Chengliang's border.

Without the interference of Prince Ping, Zhu Yidao simply lived in the Ordnance Bureau, and set up the delta wing with a group of old guys every day. But what he didn't expect was that the old craftsmen actually created a small delta wing that could carry gunpowder to the sky. This kind of small delta wing can carry a gunpowder jar of less than 30 catties and fly to a height of at least tens of zhang, and there is incense on the lead of the gunpowder canister that is a few inches long. When the incense burns to the lead, the powder jar is detonated in time, so that the delta wing becomes a standard time bomb! After a period of testing, they found that it took half an hour for every inch of incense to burn to the position of the lead, that is, when it was necessary to blow up the city gate, an inch of incense was left on the lead, and it would explode after only half an hour after it was lit; This makes it possible to accurately timed the detonation of the powder canister.

The wisdom of the people is endless! Lao Zhu could only sigh like this, under the careful design of this group of old craftsmen, the small delta wing, which was originally of little use, became the most terrifying air killer, and after countless experiments, it could even control the gunpowder jar to explode on the city gate building! However, it is not completely without shortcomings, the biggest role of the small delta wing is to attack at night, using a short distance, a suitable angle, it can go to the sky to carry out a surprise attack on the enemy camp or city, which completely makes up for the shortcomings of the Franc machine cannon that cannot be used at night! But the advantage is the disadvantage, it cannot be used in the daytime, and once it is spotted, it can be shot down with a bow and arrow.

But even so, being able to compensate for the shortcomings of the Franco cannon at night is already a huge improvement! When the small delta wing has formed combat effectiveness, the Ming official army can truly be called capable of night fire! Of course, it is still not usable in rainy weather. At present, Lao Zhu's main direction of attack is to try to produce firearms with all-weather combat to fill the gaps and problems of the Ming Dynasty officers and troops in the complex climate environment.

But it's so hard to do that! But Lao Zhu found a weapon that shocked him extremely much, that is, the Five Thunder God Machine. This thing was invented and created by Qi Jiguang in the north, with three eyes, five eyes, seven eyes and other specifications, mainly used to defend the Mongolian cavalry at the head of the city. The main method of use is that one person brackets, turns the barrel, and the other person aims and shoots, and the range is 400 steps, that is, about 180 meters. The first time he saw it, he felt that it was the first revolver!

Talent! Qi Jiguang is definitely a natural talent! Zhu Yidao's admiration for the late general was as continuous as a surging river! He immediately suspended the all-weather study of firearms, which had made no progress, and instead made every effort to reduce the size of such firearms and unify them. But to do this, a high level of smelting is still required, Zhu Yidao thought about it, and planned to make a miniature version of the shells of the Franco cannon, and change all the guns to small calibers!

Easier said than done. Because this is gunpowder or black powder, it is composed of saltpeter, sulfur and charcoal, and its properties are very unstable. And the power of burning is not great, and the smoke is very large. No way, this is a typical incomplete combustion, Zhu Yidao can only meditate and think about it, he clearly remembers that there was a more advanced gunpowder that replaced the black powder later, what is its composition?

I can't think of it at all, at this time, Lao Zhu sighed helplessly, I hate less when the book is used! Why didn't you read more extracurricular books back then? It is useless to regret it, he can only make limited improvements to the five thunder god machines, on the basis of seven tubes, reduce the diameter of the tube hole, increase the number of tubes, reduce the volume, reduce the weight, in fact, just add one hole. But even this one hole took a lot of effort from the old nose. Zhu Yidao's version of the Five Thunder God Machine has eight tube holes, but because the weight is reduced, the volume is also reduced, so one person can complete the function of turning the tube ignition. Looking at this improved version, Lao Zhu couldn't feel any sense of accomplishment, although Bi Fei and the others praised him.

He suddenly remembered something about himself! On the basis of this version, local improvements were made again: the eight tube holes were combined to form a large iron camel, and then a rotating iron camel's central axis was added under the barrel; When firing, first put this thing on the ground, then ignite it with one hand and turn the runner with the other, and when the eight shells in the runner are finished, you can continue to fire with a big iron camel! Gunpowder and shells can be placed in the big iron camel in advance, which means that as long as the baggage team carries a large number of these runners, it can still continue to fire, temporarily solving the problem of continuous firepower.

On the shooting range opened up at the request of Lao Zhu, he first dug a trench that was not deep, and then put the new version of the Five Thor rack inside, with the barrel exposed to the ground; Then he himself jumped into the trench and shot. There are already three reels next to it, and after playing one, you can replace the other one in a very short time, which greatly increases the rate of fire! According to the current weight of the Ming sergeant, he can carry a barrel of five thunder god machines and four runners. As long as the wheels on the baggage cart are sufficient, a sergeant of the general banner can resist the attack of at least thousands of Mongolian cavalry in the right terrain!
