It's going to be a busy day, Li Xi got up early, followed Guan Xuan to have breakfast, pinched the little girl's cheek and went out, Guan Xuan's face was a little sullen, and he could only leave it behind for the time being.

It's normal for Guan Xuan to be unhappy, if she wants to change someone else, even if she loses her temper arrogantly without being pampered, she will try her best to get to the bottom of it, and the little girl is very well-behaved, she didn't ask a word, but Li Xi didn't explain it clearly, and she always couldn't let go of it.

Since last night, Li Xi has not wanted her to warm up the bed anymore, and even the natural intimacy of the usual ones has decreased a lot, for example, every time Li Xi gets up, he has to use Guan Xuan as a device to practice lifting barbells, push-ups and sit-ups, and from today onwards, there will be no more.

There are still a few days, Guan Xuan is about to reach the age of twelve and thirteen, and the little girl has kept up with nutrition in the past six months, and her body is gradually growing. Li Xian didn't feel anything at first, but as soon as he came into contact with Yan Sanniang, the man's surname, who had been suppressed by heavy thoughts, began to move. He is not a saint, so it is naturally difficult for him to achieve emptiness. I no longer have to close the warm bed, what I am afraid of is what evil thoughts I have...... No, it's because I'm afraid of being pushed by evil thoughts to do something evil.

It's not good to explain carefully to Guan Xuan, saying that when she grows up, whether men and women can give or receive kisses, the little girl will definitely ask righteously, is it your mother-in-law, why do you give or receive kisses? said that she hadn't grown up yet, so why care about intimacy, this demon couldn't be expressed, Li Xian had to be perfunctory.

Chinese New Year's Eve is approaching, and the top management of Qingtian Company has to hold an annual meeting before the holiday, of course, it is not the annual meeting of the company that Li Yan ate and drank and had fun in his previous life, but to unify thinking and determine the focus of next year's work.

This is an enlarged meeting, not only will the director participate, but also the core figures above the deacon level will attend, but when Li Shi arrived at Tingtao Tower, he found that Guan Tian and the others had not yet arrived.

The R&D base of the Ministry of Zuo is leaning against a small lake, which was originally just a waterhole at the end of the small river under the waterfall, and was later surrounded by a dam built by Li Shi to form a lake, and the mouth of the dam is a drainage vehicle, which is connected to the shore and becomes a hydraulic machine, with a forging hammer and a drilling machine. In the past four months, Li Xi has not forgotten to climb the science and technology tree, but most of his efforts have been used in the basic field, especially to improve the gear transmission system. At present, the hydraulic mechanical transmission uses cast iron gears, plus screw transmission, and the belt has not found enough durable materials to play the role of the main transmission.

"According to your method, pull it with a waterbed, and this rifling can be pulled out, but it can come out...... It's a real hassle to use. ”

Tian Dayou still looks like a decadent beard with a scum, and his eyes are even more bloody with the excitement of staying up all night and working hard.

"I studied with Lao Guan and Lao Mi, and I think it is caused by a series of problems, and it is difficult to stabilize the left and right, so as you said, what can be achieved...... Industrial products. ”

Yuda Daiyu took him to the valley outside the base, which was a shooting range, and there were wooden stakes standing a hundred paces away, one of which was hung with concentric circle target paper.

Tian Dayou waved his hand, and a team of guards carried things to the shooting position, Luo Tangyuan in the guards rubbed his palm, with an excited face, the top-secret weapon was tested by him, a recognized marksman.

With a thick stock, flintlock machine, barrel and four riflings, this gun is completely the image of the nineteenth century. The front-loading rifled gun was another breakthrough made by Li Shi after the stable flintlock machine.

Rifled guns, mini bullets, and the big killers of people who have traveled through ancient times, of course Li Shi wants to come up with them, even if they can't be installed for the time being, they have to be used as strategic technical reserves, and they have been working this. The diagonal folding of the parallel lines can produce a spiral line, and then there is a hydraulic drilling machine to adjust the operation mode, and it should be a matter of course to drill the rifling line with water power. And Mini bullet ...... It's just a mouthful.

But between reality and dreams, there is always too big a gap, Tian Dayou talked about these troubles before, Li Xian thought that this period of time could be improved, but he didn't want to make little progress, and now he had to follow Tian Dayu to see for himself, wanting to know where the problem was.

Boom...... The gunshot rang out, and a cloud of sawdust exploded from the wooden stake in the distance, and the guard who was watching the target raised the sign, Six Rings, which means that Luo Tangyuan aimed at the middle of the chest of a person a hundred steps away, and the bullet hit the forehead or thigh, which is a distance of one hundred and thirty or forty meters.

Receiving an approving look from Li Xian, Luo Tangyuan smiled, and then began to wipe the gun. When Li Xi saw this scene, his brows suddenly furrowed. Luo Tangyuan inserted the whole strip with a coarse brush on the front end into the chamber of the gun, turned it vigorously for a while, and then shook the gun upside down for a while, shaking out a lot of fine lead filings, and then the gun stopped moving.

"The next shot? At least wait...... In a few minutes. ”

Tian Dayou answered Li Shi's question like this.

"You have to wait for the lead filings in the chamber to cool down, and then pass it again, if you don't clean it thoroughly, it's easy to blow up the chamber. There have been problems before, thanks to your reminder, you have to check the barrel after every test gun, and that time it was just a crack in the barrel. ”

When Tian Dayou said this, Li Xi understood that this was a common problem of hanging lead and Minnie bullets. The solution is also very simple, that is, instead of pure lead, add tin to make lead bullet harder.

But then the problem came, the buckshot was hard, and the cavity underneath was difficult to open. This problem can also be solved, for example, in the early Minnie bullets, which were filled with a wooden plug in the bottom cavity and used a faster firing propellant.

But...... Then there is the problem, the bullet is hard, and if it can't be fired a few times, the rifling will wear out, and the quality of the barrel will be tested with rapid-ignition charge. To solve this problem, it is necessary to improve the material of the barrel, and improve the material of the barrel, or even directly use steel...... We'll have to work harder to drill the rifling.

The barrel was hard enough, and then it was a lead again...... Is it possible to have copper poured? This is an interlocking system engineering, and retrospectively is the basic steel thing.

"This rifled gun, the requirements for the barrel are not generally harsh."

Tian Daiyu also complained to the point.

"Although it is now possible to make barrels with hydraulic hammer drilling machines, the quality of wrought iron is unstable. The quality of each furnace of wrought iron depends on experience. How many times wrought iron can be beaten on the forging hammer to form a barrel depends on Lao Mi and his apprentice to keep an eye on it. Not only us, but also the wrought iron bought from Foshan is like this, each batch is different, and the rifling line has to be controlled by people. ”

"There is a difference in the softness and hardness of the barrel, drilling with a waterbed, each barrel has to adjust the drilling method, and the final barrel can only be used for rifling, only the actual test gun knows. How accurate the barrel can be drilled out and how long the rate of fire is, you have to determine by a gunner like Xiao Luo, which is completely different from a shotgun. ”

Tian Dayou nagged for a long time, and then sighed with emotion.

"It's a dream to be able to get the machine done with a clatter."

Li Xian pondered for a long time, and felt that a crossing myth had been quietly shattered, and it seemed that this so-called crossing weapon was just a novelist's words. Europeans can play Mini bullets, it is because of the mature steel industry, there are conditions in basic materials and production processes, that is, controllable and measurable mass production, relying on handicraft workshops to line rifled guns Mini bullets, there is really no hope.

"Although this gun is accurate, it is too troublesome, in fact, it is not as good as our shotgun. The finely ground waterbed that Tian Sidong Guan Sidong and the others have figured out can sharpen the barrel of the shotgun to a smooth one, and I can probably shoot it at a distance of 100 steps. ”

Seeing that Li Shi and Tian Dayu were both frowning and pondering, Luo Tangyuan interjected.

It seems that the right fit is the best...... Li Xian's somewhat frustrated heart lifted, it doesn't matter if he doesn't have a rifled gun for the time being, and continuing to make a fuss about the smoothbore gun is also a way out. The smoothbore gun is naturally difficult to compare with the rifled gun in terms of accuracy, but with a lot of effort, the accuracy of the 100-step distance can still be relied on, and what is more valuable is that the process is simple, the cost is low, it can be reliable, and the service life is long.

In the second half of the 20th century, smoothbore technology blossomed in artillery, while the British had accumulated too much in rifled technology, and in the 21st century, they were still obsessed with rifled guns. There was a famous saying in the previous life, calling to take the development path that suits you, and now in this era of insufficient conditions, you have to climb the technology tree that suits you.

"Make a few branches for later use, leave a few apprentices to continue pondering, Uncle Tian, don't worry about this matter anymore."

Li Xian made a decision, and he did not expect this gun to be equipped on a large scale, but only used it as a sniper rifle.

"By the way, Uncle Tian, didn't you stop staying up late, there is still a meeting today, have you forgotten?"

Then as soon as Li Shi said this, Tian Dayou patted his head, he really forgot.

Not only did he forget, but Guan Fengsheng and Mead Zheng also forgot that Mead, the big stove head in the past, was now also the head of the department, and the iron workshop was handed over to the assistant assistant on the next floor.

When they arrived at their artillery workshop, the two were arguing, and at present, Li Shi's general department was a gun family, and Mead was more experienced, and he was spanning several fields. This will be him arguing with Guan Fengsheng about whether it is better to use a drill hammer or a straight hammer.

In the past few months, the pig iron smelting technology has also made progress, and the quality of the cast iron has surpassed that of Foshan, so Li Xian wants to see if he can directly hammer the barrel on the solid cannon blank with water power like the British.

This is just an idea, Guan Fengsheng and Mead are giving two ways to achieve it, one is to use brute force to hammer it, and the other is to use a big drill to drill. The former is slow and simple, while the latter is theoretically more efficient, but requires a strong transmission system, which is expensive and may not work.

"Fourth brother...... We can't keep up with this money......"

Tian Dayou was inclined to Guan Fengsheng's straight hammer method, to be precise, he was inclined not to do it, and the reason why Guan Fengsheng insisted on this method was also for the purpose of saving money.

"Well, that's what we're here for."

The cannon was really not in a hurry, Li Shi beckoned everyone back to Zhuangzi, and he was about to explain the matter.

Guan Fengsheng, Tian Dayou, Lin Dashu, Wu Yaluo, He Gui, and five directors.

Wu Chong, Mi Dezheng, and Liu Xingchun are the three principals.

Wang Deng's family, that is, Wang's widow, Cai Beishan, that is, Cai Langzhong, they all entered the inner circle of Li Xi, and they all had the position of supervisor, and there was also Gu Xiyin, who was the son-in-law of Yiming Lao Dao and Liu Xingchun's brother-in-law. Originally, he was doing the work of the bookkeeper, but now he has become a direct subordinate of Tian Dayu, who is in charge of the general ledger of Qingtian Company, and also has the position of supervisor.

Jia Hao and Wu Ya, the two generals of Li Shi, attended the core meeting of the Qingtian company as the chief of the guard, equivalent to the deacon.

There are two other people hidden behind the scenes, that is, Duan Hongshi and Yiming Lao Dao, they are guest secretaries, they only listen and don't speak, and they don't talk to others.

"Now our company's harvest depends on crystal glass and horse lanterns, even if the trade route is smooth, and Guangzhou Anhetang can join forces, and the next year will not be more than ...... The prospect of 500,000 taels of silver. ”

Tian Dayou took Gu Xiyin's report, made a rough calculation, and gave a revenue estimate. This number makes some people gasp, and that's not enough!?
