When Mao Yuanyi and Zu Dashou heard it, it was unimaginable, just because there was a scratch on the inner wall of the gun tube, there would be this effect, how could this feel very unreliable!

But the facts are in front of them, and the two of them can't refute it. Looking at their expressions, Bi Maokang said with a smile: "The truth is true, Your Majesty once said it, and I still don't understand it very well. ”

Speaking of this, he bowed to Emperor Chongzhen and said, "Please also ask Your Majesty to explain it again for your ministers!" ”

"Your Majesty, please give me some advice!" Mao Yuanyi bowed sincerely and immediately followed.

Zu Dashou was also very curious, and he could let the emperor give advice, which was also an honor, so he also agreed. Even Li Dingguo blinked his curious eyes and joined the ranks, not realizing that his identity seemed to be unqualified.

When Emperor Chongzhen heard this, he met their requirements and explained to them: "Actually, the rifling in this is spiral-shaped, and if the lead bullet is slightly larger than the gun tube, the lead bullet can be deformed and embedded in the rifling. Because of the good air tightness, the energy generated by the gunpowder discharge can be converted into more kinetic energy to propel the lead ejection chamber. And because of the spiral rifling, the lead is rotated forward after the ejection of the bore, which greatly improves the stability and ...... of the lead bullet in the air."

According to the experience gained by later generations, he explained a lot in a lively manner. After finishing speaking, he suddenly found that the Ming officials in front of him were all confused. Yes, it seems that there are too many technical terms, so that they can fully understand, but it is a bit difficult for them!

After Emperor Chongzhen finished speaking, Bi Maokang came back to his senses first, and couldn't help but praise: "Your Majesty's knowledge is profound, and it is really beyond the reach of the ministers!" ”

"The last general is simply stunned, Your Majesty's knowledge is really profound!" Zu Dashou said with admiration.

Before Mao Yuanyi could follow up, he took a picture of Emperor Chongzhen's sycophancy, and Li Dingguo, who was on the side, interjected and asked, "Your Majesty, what is kinetic energy?" Why does spiral rifling keep lead bullets stable in the air? And ......"

His questioning made several courtiers stunned, and when they turned their heads, their faces were a little unsightly. But the other party is just a child, can he see it in general?

Emperor Chongzhen listened, but he smiled, and appreciated Li Dingguo's attitude of getting to the bottom of the matter, and immediately replied: "These questions you asked involve basic disciplines such as physics, I have already written a part, and I will try one or two when I go back, if you are interested, I can let someone tell you about it!" ”

On the side of the inner study hall, some smart and clever chamberlains have been selected to start learning. When they learn it, they can become teachers of basic subjects and train more students. With this scientific knowledge, you can do it yourself without those Western missionaries!

After hearing this, several courtiers once again realized the weight of this half-grown child in the emperor's heart, and couldn't help but secretly pay attention to this child named Li Dingguo in the future.

As Emperor Chongzhen, as the Ming Emperor, naturally has a lot of things, such as going back to the imperial garden to watch Tian Guifei dance, playing chess with Yuan Guifei, and talking to the queen about his heart. It was impossible for him to discuss those details again.

Now that the flintlock test is complete, he is ready to return to the palace. As he walked out, he talked to his cronies and courtiers.

"From the test just now, it can be seen that the flintlock pistol must be equipped with the Ming army. At this point, the production of the Ordnance Bureau must be increased! ”

When Bi Maokang heard this, he agreed, and then hesitated slightly, but he still couldn't help but say nothing.

"As for this flintlock rifled gun, it is too slow to load, and Bi Qing will also think of a way. By understanding the principle and seeing how it can be improved, you can speed up this reload! ”

"Yes, Your Majesty!" After Bi Maokang agreed, he wanted to speak and stopped.

Mao Yuanyi, who was on the side, had endured it before, until this time he saw that the emperor seemed to have finished explaining, so he hurriedly played: "Your Majesty, can you directly equip the new army with this rifled gun?" Even if the reload speed is slow, as long as the amount is large, it can still exert its power on the battlefield. ”

When he came over just now, he had already thought about it, the three-stage shooting was too slow, so it would be better to make a five, six, seven, or eight stage. The front two rows are transferred to shooting, and the back rows are loaded with them!

Hearing this, Bi Maokang couldn't help it anymore, and had to say: "This rifled gun is very troublesome to build, and the cost of manpower and time is several times that of ordinary flintlock pistols. Not for at least not for the next few years! ”

Hearing this, Mao Yuanyi was suddenly dumbfounded. Zu Dashou on the side was not as hit as he was, after all, he knew that this good thing would definitely be given priority to the new army, and it would not be his turn to be in the capital camp.

Seeing Mao Yuanyi's appearance, he seemed to be hit a little hard. Think about it, it's a thing I'm looking forward to, and when you want it the most, you suddenly tell you, I'm sorry, for objective reasons, you can't meet this request, this feels like a hehe.

Emperor Chongzhen smiled and comforted Mao Yuanyi and said: "The Ordnance Bureau will find a way to improve the process, and in addition, by next year, it should also be able to equip the new army with a squad of rifled guns, which can be used for special operations. ”

When Mao Yuanyi heard this, he also felt that it made sense, so he was relieved, and replied: "It's the minister who is too anxious!" ”

As he spoke, he had already arrived at the gate of the camp. Emperor Chongzhen left and returned to the palace, only Bi Maokang was still on his side. It was only then that he said to the emperor: "According to Your Majesty's instructions, the ministers use flowing water to operate, and use water power to drill the chamber." Nowadays there is a problem, it seems that the power of water power is not enough! ”

The use of water power in the Ordnance Bureau is completely man-made, and this Emperor Chongzhen has seen it beforehand. If you want to increase the water power, you have to take advantage of the water flow difference, which is not very easy to do for the current Ordnance Bureau.

After hearing this, Emperor Chongzhen did not think much about this, but immediately thought of the steam engine. So, after he instructed Bi Maokang to find a way to solve it, he first transferred to the military battle bureau.

The steam engine still hasn't been built, and in the process of building it, there are many problems. The main thing is the conversion between several energies. Emperor Chongzhen thought for a while, and decided that he would come to the military bureau more to bake the fire for the winter this winter. His goal is to come up with a prototype of a steam engine next year. After all, this thing is the power source of the industrial revolution, and only by making this thing can the Ming Dynasty undergo earth-shaking changes.

Different from the chic days of Emperor Chongzhen's combination of work and rest, Emperor Taiji, the head of Jianyu, is almost gray these days. No, I didn't even care about eating lunch, so I summoned Fan Wencheng to discuss things!
