Cao Huachun's voice, so exaggerated that he could squeeze out sunflower oil, came out when he stepped into the courtyard of Wenhua Palace.
The several figures of different heights in front of the camel immediately turned around.
The fifth prince Zhu Youjian was the first to run forward and salute.
The half-year-old boy was just growing up. After not seeing him for half a year, Zhu Youjian had grown a lot in height and his shoulders were wider. However, he was only eleven years old after all, and he regarded Zheng Haizhu as the benefactor of his mother's revenge.
Therefore, when he jumped over in three steps and two steps at a time, his whole body exuded the childish air of a puppy having fun.
Lu Xiangsheng walked over and said to Zheng Haizhu with a smile: "The students all know that the teacher is back today and is ready to hand in his homework."
Zheng Haizhu smiled and responded with interest, but his eyes quickly passed over Lu Xiangsheng and fell on the face of the emperor's eldest son Zhu Youxiao behind him.
"Master Zheng..." Zhu Youxiao performed the student's courtesy as he did to Sun Chengzong and Xu Guangqi.
But the place to stop is not as close to Zheng Haizhu as his younger brothers Zhu Youjian and Lu Xiangsheng.
It seems that even just one or two more feet of distance is a good way to relieve the cramps.
This distance allows the two masters and apprentices, who have a grudge against each other because of Ke Yinyue's expulsion, to complete a less embarrassing reunion and greet each other while maintaining a sense of distance.
In a brief moment, Zheng Haizhu had already seen the small hammer in Zhu Youxiao's right hand, as well as a large pile of wooden frames and iron nails at the camel's feet not far away.
Obviously, that was what Lu Xiangsheng said was "the lesson to be handed over" - at the beginning, Zheng Haizhu ordered Wei Zhongxian to take the camel back to Beijing, and asked the two Zhu brothers to think about a camel gun mount that could be mounted on the camel's hump.
Zheng Haizhu suddenly felt an emotion that he couldn't tell whether it was joy or tenderness, filling his heart.
The seventeen-year-old young man in front of him, the imperial prince's heavenly aura, was isolated outside the palace wall just like the cheers of the courtiers and the gossip of the common people.
At this moment, in the eyes of the senior teacher, Zhu Youxiao's simple and beautiful temperament is exactly the same as that of those diligent civilian students in Songjiang. It is a kind of curiosity that focuses on studying things to gain knowledge, and an active ability to create.
.
Good boy, my good disciple...
Zheng Haizhu didn't even have the time to clearly touch her spontaneous feelings, as if she were licking a calf, and the warm light in her eyes flowed out naturally.
Zhu Youxiao was stunned for a moment, and soon the tension in his mind seemed to loosen.
The corners of his mouth and forearms were raised: "Master Zheng, look at the shelf that my fifth brother and I made."
Cao Huachun also hurriedly joined in the flattery and said: "That's right, when I just left the Qianqing Palace, Long Live Master praised my brothers. It's more interesting to think about this new French firearm than to think about the Crystal Palace in the pond or the self-ringing clock in front of the balcony."
Zheng Haizhu said warmly: "As long as it is done authentically, it is a good craftsmanship. The two princes are so smart, they can master whatever they learn and do what they want."
While talking, several people came to the camels again. Lu Xiangsheng explained: "The two camels that Madam sent back, the gun mounts between the twin peaks, the prince and his ministers, made this double-eaves roof style, with the front high and the back low.
, the two wooden beams on the left and right should be stable. The trouble is the dromedary camel..."
Zhu Youxiao and Zhu Youjian stood on both sides of the dromedary camel, holding the prototype gun mount with four hands.
Zhu Youxiao took Lu Xiangsheng's words and demonstrated it to Zheng Haizhu while wondering: "Master Zheng, according to what you said, the camel is not only used as a pack horse, but the gunner and gunner also need to sit on the back of the camel.
, hold firearms and line up to meet the enemy. Bactrian camels are fine, but for single-humped camels, if the gun mount is behind the hump, the rider will have no place to sit. If there is room for the rider on the hump, how can the frame be stable?
Where’s the stand?”
Zheng Haizhu has actually been thinking about this issue that troubles the Zhu brothers.
As for the camel cannon, the reason why she, a modern person who specializes in the history of the Ming and Qing Dynasties, wanted to build it in the late Ming Dynasty was just because she remembered that when the Qing army conquered the Junggar tribe in history, they encountered the Junggar camel cannon array and lost their troops and generals, which is famous.
Longkodo's uncle was also bombarded to see the King of Hell.
But when it comes to practical operations, Zheng Haizhu has no system to ask for a golden finger on how to solve the technical difficulties of the gun mount using this hot weapon attack method passed down from the Persians who were good at training camels.
It wasn't until she went to Chahanhot, the royal city of Lin Dan Khan, that Zheng Haizhu suddenly got inspiration.
"Bactrian camels are big and can be used for cannons, but they run slower and are much more expensive to buy from the barbarians. We use camel formation because camels are cheaper than war horses, and heavy muskets are not as heavy as turtle doves. Dromedary camels
It can resist, so we can’t give up on the dromedary camel.”
Zheng Haizhu said, waving to the two little firemen who came to the Wenhua Hall with Cao Huachun.
The little fireman hurriedly carried the load over. After putting down the pole, he opened the big wooden box and carefully took out several wooden utensils of different sizes.
"What is this? Umbrella ribs?" Zhu Youxiao asked curiously.
"Guess again, Your Highness, this is something the Mongols use to live and work in peace and quiet." Zheng Haizhu inspired him as he held up a piece of wood.
"Ah, I understand," Zhu Youjian replied quickly, "This is the roof of Qionglu."
Zheng Haizhu nodded and handed the wooden tool to Zhu Youxiao: "Yes, it is the Qionglu where the Mongolians live. Our border troops of the Ming Dynasty call them yurts. But the yurts built by the Mongolians who are marching or grazing are very simple.
And this time in the royal city of Chahar, the yurts I saw were not only gorgeous and luxurious, but the wooden beam structure of the dome was also ingenious. At that time, I thought that the hump, like this yurt, is not the same as the shape of a wowotou.
So? So, whether I entered Lin Dan Khan's tent or his Yalu in Fujin, I wrote down the structure of the wooden beams of the dome. On the way back south, I asked General Ma's soldiers who knew some carpentry to
I have made these models with great accuracy, I wonder if they may be of some inspiration to you."
The more Zhu Youxiao listened, the more sparkling light appeared in his eyes.
The future prince, who was as gifted in carpentry as his ancestor was, suddenly became enlightened while stroking the "yurt" that had shrunk a hundred times.
"Use tenons," Zhu You said to the crowd, "use tenons to connect the wooden rings, hoop these umbrella ribs, and then they can be covered on the hump. The top branch has a harpoon-like mechanism to hold the umbrella in Master Zheng's firearms factory.
Those big guns."
The Zhu brothers have been learning the knowledge of firearm attack from Lu Xiangsheng. Not only have they read the firearms books of their predecessors, they also know what the various firearms produced by the Songjiang Firearms Factory look like, so they are also familiar with the fulcrum of the heavy matchlock gun.
"Okay, let's give it a try," Zheng Haizhu said happily, turning his head to Lu Xiangsheng, "Han Changli said that I will not deceive him. Throughout the ages, his disciples have always been better than their teachers."
Lu Xiangsheng is a very thoughtful person, and he regards Zheng Haizhu as his eldest sister. Since she entered the Wenhua Hall today, Lu Xiangsheng has been listening attentively. At this moment, he immediately joined in: "So you see, Master Zheng is right.
, Only by studying physics can you develop a conscience. The wooden objects of the pavilions, doves, carriages and boats that the two princes had previously made were not made in vain. Which of them did not use tenons? "
Zhu Youxiao felt sweet and happy after hearing this, and for a moment he felt that Master Zheng and Master Lu were really the best teachers in the world.
"By the way," Zheng Haizhu said to Lu Xiangsheng as if he was remembering something again, "Tomorrow you come with me to Honglu Temple. Lin Dan Khan has a tent car as a national gift to the Emperor of Heaven, and it stops at Honglu Temple.
Lu Temple. There are some components of that tent car, which I think can be converted into a foldable gun mount. Go and have a look. If you understand, I will tell you the details to the two princes."
