Chapter 622 Rifled gun (third update)
After Bi Maokang finished his introduction, Emperor Chongzhen walked up to the drill stand, pointed to the drill stand and said, "Bi Qing, I think you might as well consider improving this drill stand. Try changing the pull to hydraulic pull."

What he mentioned was actually a hydraulic machine tool.This is simpler. After the steam engine is built, it will be more convenient to use steam power instead of water power.

Naturally, Bi Maokang had seen the water power used in the farmland, so it was easy for him to associate it with Emperor Chongzhen's suggestion.He is a technical official, so he naturally understands the use of water power.However, he hesitated a little and said: "Your Majesty's words are very true, but there is no river here in the Weapons Bureau..."

Emperor Chongzhen was speechless when he heard it, and it seemed that the technical people had a single-mindedness, so he interrupted him and said, "It's not for you to apply water power on a large scale, but for you to experiment to see if this method can be successful and can effectively reduce the water power. The waste of manpower can speed up the manufacture of self-generating firecrackers. You can completely let the craftsmen make a hydraulic drive to try."

When Bi Maokang heard this, he was slightly taken aback, then patted his forehead, showed a very embarrassed smile, then bowed his hands, and replied sincerely: "Your Majesty is right, my minister is really confused!"

Emperor Chongzhen didn't take it seriously either. He smiled and asked someone to take a flintlock gun. He looked left, right, up and down, and even looked at the barrel.He straightened his bird's beak and pressed the trigger again, trying the feeling of firing a gun.

When Bi Maokang saw it, he introduced the performance of this self-generating gun and introduced various parameters.After hearing this, Emperor Chongzhen smiled and said to Bi Maokang: "From now on, let's call it a flintlock gun. It's a good job. But it would be better if the range is longer!"

When Bi Maokang heard this, he quickly replied: "Your Majesty, if the range of this self-produced flintlock gun is to be increased, the barrel must be lengthened and thickened, and the gunpowder used for firing must be increased. It is more difficult. And even if it is built, the weight of the flintlock gun and the force generated when it is fired may not be controlled by a single soldier."

At this time in the late Ming Dynasty, the length, weight, etc. of the firecrackers have actually been improved through the ages, and a set of mature regulations have already been established.Bi Maokang thought that Emperor Chongzhen didn't know this, so he explained it in detail.

But what he didn't expect was that Emperor Chongzhen shook his head and said with a smile: "That's not what I mean, what I mean is, look, arrange someone to pull out the rifling on the inner wall of the gun barrel, the rotary type .So softer lead bullets will fly in rotation when fired after they are plugged. Compared with smoothbore, they will have stronger kinetic energy and more stability. In this way, not only can they be shot more accurately, but they can also be shot more accurately. Far."

When Bi Maokang heard this, he was stunned for a while. After thinking about it carefully, with his knowledge, it was still difficult to understand, so he couldn't help but feel a little nervous.I claim to be No.1 in firearms, and I am proficient in firearms, but the emperor pointed out a few places when he came, and I could still hear and know how to do it before, but I just didn't expect it; but now, the emperor didn't understand what he said. This... this is really ashamed!
Thinking of this, he asked a little curiously: "Your Majesty, can this really shoot more accurately and shoot farther?"

"Hehe, Bi Qing doesn't need to ask me." Emperor Chongzhen smiled and handed him the flintlock gun in his hand, and then said, "Bi Qing made it himself and compared it, then everything will be clear!"

When Bi Maokang heard this, he also laughed. This is indeed the most convincing method, but he looked at the flintlock gun in his hand and thought for a while, then frowned and said: "Your Majesty, you have to carve the gun on the inner wall of the barrel. It may not be easy to rotate the rifling. If such a process is added, the labor time will be longer and the cost will be much higher."

When Emperor Chongzhen heard this, he didn't take it seriously and said: "It's okay, let's try it first, and then evaluate how much the cost will increase after making it? Then compare it with ordinary flintlock guns to see how much the performance has improved? Decide whether this rifled flintlock is to be built, and whether it is to be equipped with the army."

When Bi Maokang heard it, he understood that the emperor did not directly issue an order, but just conduct an experiment first, and then make a decision after the results, so that the pressure on himself will be much less.

Thinking of this, he breathed a sigh of relief in his heart, and immediately replied respectfully: "My minister obeys the order!"

Emperor Chongzhen walked to the warehouse where the flintlock guns were stored, and was very happy to see more than 300 flintlock guns on display there.However, the new army has already started, at least the first battle will not use the flintlock.When we come back after the end of the battle next year, we should be able to have an extra group of flintlock troops.

Thinking about this, he said to Bi Maokang who was by his side: "I will teach Mr. Mao to select soldiers from the Beijing camp, and then buy flintlock guns for training. When Qing's production increases, the cost will come down." , that is the time for a large-scale deployment of the army."

Bi Maokang was overjoyed when he heard that, the Armament Bureau has now embarked on the road of innovation, and must be responsible for its own profits and losses.The flintlock gun that was built is the flagship product of Bingzhan Bureau, and if it can be recognized, the road ahead will be much smoother.

He thought so, and immediately responded loudly: "Don't worry, Your Majesty, I will definitely improve the manufacturing process as soon as possible, increase the production of flintlock guns, reduce the cost of flintlock guns, and at the same time strictly control the quality of flintlock guns. "

Emperor Chongzhen was very satisfied, and immediately went to the Military Bureau after leaving the Military Bureau.Since the last time he described the prospect of self-propelled warships to Zheng Zhilong, he has ordered the Military War Bureau to build steam engines.Just now I mentioned the steam engine again in the Military Weapons Bureau, so I stopped by to see how the situation is going.

To his slight disappointment, the construction of the steam engine did not go smoothly.Emperor Chongzhen asked for the drawings and checked the whole process.Then he pointed out several design errors on the drawings, and then emphasized the significance of this steam engine, and ordered skilled craftsmen to build one first to have a look.

With Daming's technology at this time, regardless of the cost, it is not difficult to manually build a steam engine. At most, the sealing is not enough, the power is lower, and the cost is higher.

When he returned to the palace, the servant came to report that the assistant minister Zhou Yanru had returned and was waiting to see him.

When Emperor Chongzhen heard this, he glanced at the memorial that had already been placed on the imperial case, and then gave orders lightly to let Zhou Yanru have an audience.

Not long after, Zhou Yanru went to Wenhua Hall to have an audience.Emperor Chongzhen could tell that he looked better than at the beginning of the year, and he seemed to be a little fatter. It was obvious that he had a comfortable and happy life after going out.

Zhou Yanru below is indeed in good spirits.And he hoped that the emperor would reward him later.

　The monthly ticket is 50 more, and the recommendation ticket is 400 more, that is, two additional changes, and if you pay this change, there are still 6 owed changes.
