"That's right! It's a rear-loading gun. Yinzhen couldn't help but be very excited, dealing with this kind of person with strong comprehension ability, but it was a lot easier, he smiled: "You try it, if you can load the shell from behind, the speed of firing and the speed of cleaning the cannon can be several times faster, and if you can load from behind, this rifling does not need to be straight, and the accuracy can be improved a lot, in addition, you see if the shell can also imitate the sub-gun of the 'Franc machine'......"

As he spoke, Yinzhen squatted down, casually folded a branch and drew a picture of a pointed cannonball on the ground, "If it can be like this, the firing speed of this cannon will be faster." ”

Dai Zi stared at the sketch for a long time before he unfolded his furrowed brows and said in a deep voice: "Master, the slave has been immersed in firearms for a lifetime, and I have not heard of such an unbelievable idea in Chapter 112 of the master, it is really an eye-opener, and the firearm will definitely shine in the hands of the master." However, the combination of this rear-loading gun and fixed artillery must solve two problems, one is how to tie the rear door, and the other is how to ignite. These two problems have been solved, and the cannon fires faster than the gun. ”

"Tie the back door tightly, it's called the bolt of the gun, it belongs to the mechanical category, you find some craftsmen in this area, organize them to study it well, it should be able to solve it, this king heard that make a mat with cork in the rear muzzle can prevent air leakage, you might as well try it." Yinzhen carefully advised: "The problem of ignition can only be explored by you, and this king has no experience." ”

"When the minions go back, they will gather people to ponder these two issues." Dai Zi bowed and replied.

"Well, you should also pay attention to secrecy." Yinzhen instructed, and then said: "The front-loading artillery is on the ship, whether it is loading ammunition or cleaning the gun chamber, it is too troublesome, it can be changed to rear-loading, but it can save a lot of trouble, this matter is directly related to the power of the battleship, you will set up a research room for the improvement of this artillery, convene experts and experienced, competent personnel to study together, work together, brainstorming, you don't have to worry about the problem of money Chapter 112 ahead of the guide, this king strongly supports, this king only hopes that the navy's warships can be equipped with this new artillery." ”

After telling Dai Zi, Yinzhen turned around and said to Chang Shan, the head of the foundry who followed: "Since the foundry can be put into production, first build a batch of old guns, as the daily training of the navy, the gunners must conduct a lot of live-fire training, you can also explore, accumulate experience in casting guns, as for the specifications and finalization of the guns, etc., are decided by Dai." ”

Later, he instructed Hu Zhiguo, the director of the firearms factory: "At this stage, the firearms factory must ensure the output of three muskets per day, and in addition, it is necessary to focus on studying and exploring how to improve the production process and speed of barrels and rifling, and constantly sum up experience. ”

Coming out of the shooting range, Yinzhen went to the ironworks construction site by the river.

Gu Mingkai, the chief manager of the ironworks, greeted him from afar, and after greeting An Jian, he reported: "Lord Wang, it is expected that in half a month, the ironworks will be completed, and now several completed blast furnaces have begun trial production." ”

Hearing that it would be completed in half a month, Yinzhen was very happy, "Let's go, go and see the blast furnace that has been put into production." ”

Just approaching the blast furnace, he felt a wave of heat rushing to his face, and seeing that the blast furnace was busy, Yinzhen consciously stopped. As soon as he passed, a group of workers wanted to ask An to salute, don't disturb their serious business, but a few old craftsmen saw him coming, and hurriedly rushed over to ask for peace, Yinzhen smiled and asked them flat, and asked casually, only to know that all the blast furnace smelted is white iron, and if you want to get gray iron, you can also soften the pig iron, and then refine it to get the gray iron suitable for casting artillery.

Yinzhen didn't understand this thing, Wen Yan encouraged him a few words, and he was about to go back, but when he turned around, he met the car delivering charcoal, and couldn't help but ask casually, "Do you make iron or use charcoal?" ”

A craftsman hurriedly bowed down and replied: "Back to the prince, although the coal is hot, the iron that can be smelted is not of good quality, so I have been using charcoal." ”

Ironmaking, Yinzhen doesn't understand, he still knows the common sense of using coke to make steel, and immediately said: "Coal is not good, you can use coke, and the West is now using coke to make iron." ”

Gu Mingkai frowned and said: "Coke iron smelting, it seems to be recorded, it seems that coke was used to smelt iron in the Song Dynasty, I will go back and check." ”

The Song Dynasty had it? Yinzhen has a big head for a while, it's sad that he doesn't understand history, he knew that the Song Dynasty existed, and he could use the Westerners as a shield? He couldn't help laughing and said: "Well, check and check, find a few more places to try a few times, and see which place produces the most suitable coke for ironmaking, ironmaking is very important, everyone use their brains more and brainstorm it." ”

Hearing Yinzhen's words, Gu Mingkai said mercilessly in front of a few old craftsmen: "They all cherish themselves one by one, for fear that their crafts will be stolen by others, the current atmosphere of the ironworks is very bad, and every link is afraid that their crafts will be stolen by others. ”

Several old craftsmen were blushing when they were all said, but this was a fact, and they didn't dare to argue with it.

When Yinzhen heard this, wouldn't this be my hard work, after thinking about it, he smiled and said: "This is also human nature, they are afraid that they will teach the apprentice to starve to death of the master, right?" After glancing at a few old craftsmen, he said in a deep voice: "Gu Mingkai, three craftsmen are selected from each link of ironmaking to form a research group, specializing in the study and improvement of all aspects of ironmaking, in order to improve the process, quality and output of ironmaking. ”

As soon as the voice fell, a group of craftsmen immediately turned red-eyed, what three times the month, the heavy reward does not matter, to be able to have a son to make up for the prince's personal guard, it means that there is a background, let it out, casually are six or seven grade officials, this is enough to glorify the ancestors, proud for a lifetime.

Gu Mingkai just asked a key question, "Please also ask the prince to show me, how should the craftsmen of this research group be determined?" ”

"Let them compete freely, fight in the ring, and whoever knows more and has more experience will be chosen." Yinzhen said with a smile, I asked you to hide your secrets, now I want to see if you can still hide it?

Back in Liuchun Garden, Zhang Mengjiao personally waited for him to wash and change clothes, and when he sat down to drink tea, she handed the newspaper sent in the morning to Yinzhen, and said with a smile: "Lord Wang, you will be fined for three years." ”

Hearing that it was only a three-year fine, Yinzhen couldn't help but breathe a sigh of relief, and read the newspaper carefully, but his brows wrinkled unconsciously.

Zhang Mengjiao sighed faintly: "The prince is worried about the emperor's interference in the affairs of the navy? ”

Yinzhen nodded lightly and said in a deep voice; "The battleships haven't seen yet, and the emperor has begun to take precautions."

"Who made the prince's navy so conspicuous?" Zhang Mengjiao sighed lightly.

Yinzhen couldn't help but smile bitterly, the navy carried too much hope for him, discipline, style, tradition, sense of honor, these things must be grasped from the founding of the army, even if he was jealous of this, he did not hesitate, took a sip of tea, and then he smiled, "Tell me your opinion." ”！！！
