Soon after the appearance of pocket watches, Bailiyan devoted himself to the production of smaller watches, but due to the immaturity of the craftsmanship and technology at that time, the accuracy of the watch was too poor, so he had to give up.

In recent years, technological progress has been rapid, and the emergence of Wild Land has improved the concept to a certain extent and provided other technical paths suitable for the current industrial base.

At the same time, the assembly process has matured, the accumulated experience in the production and use of pocket watches, after continuous improvement and iteration, coupled with the optimization design of the wild, has launched many versions and models of pocket watches, and the accuracy and volume are becoming smaller and smaller, and it is only a matter of time before the watch is launched.

Women's watches are much smaller than men's watches, so the assembly and precision requirements are high, but thanks to the eagle eye of the Nilkoco apprentices and their dexterous hands, the assembly of the watch has made a qualitative leap.

Nilcocco people have more than six times the eyesight of humans, their hands are smaller, and they are hardworking and intelligent, making them ideal for making delicate and small products, and they assemble watches four to five times more efficiently than humans, and the accuracy is generally an order of magnitude higher.

At present, the accuracy of pocket watches and watches assembled by human watchmakers is ten to fifteen seconds on the best day, and nearly two minutes on the worst twelve hours.

Skilled Nilkocco watchmakers, assembling ordinary mechanical watch accuracy, generally can reach less than 20 seconds, the longer the watchmaker's working life, the higher the accuracy of the assembly, the highest accuracy of a mechanical watch, only three and a half seconds away from twelve hours, is exactly the product assembled by Nilkoc people.

Although the women's watch given to Ji Rouer is an ordinary mechanical movement, its accuracy is only half a minute a day, and the price is quite expensive.

Thanks to the new "symmetrical double flywheel movement" developed by the Nierkoko trained students and watchmakers, the university hall and the Ligong faction jointly tackled key problems, and theoretically the accuracy of the symmetrical double flywheel movement is an order of magnitude higher than that of the tourbillon movement under the same part accuracy and assembly level.

Of course, this kind of precision watch, regardless of the accuracy of the machined parts, only the assembly accuracy required is very high, almost the limit of human manual assembly, and it requires special customization by Nilkocco watchmakers, and its price is naturally not expensive.

Watches are currently limited to the military, the elite and national gifts, even if they want to buy a watch, they must get a ticket through a relationship, so that they can go to a department store to order an ordinary mechanical movement watch, and they have to queue up.

However, pocket watches are already available for availability, with much more accuracy and more models than they were years ago, and they are more than enough for timekeeping and window dressing.

As for symmetrical double flywheel movement watches, and tourbillon movement watches, most of them are used for precision timekeeping equipment, and the production is very small, and it is too wasteful to use them purely for personal timekeeping.

The train keeps going to the station of Chenling, through the vast wilderness, through the boundless wheat fields, the scenery along the way is refreshing and imaginative, many people are taking the train for the first time, and the feeling is like a dreamlike realistic interpretation.

In the afternoon of the next day, the train arrived at the west railway station outside the city of Chenling, and the Xian army cleared the south station in advance as a fast passage to facilitate the passage of the Zhiguo mission and the forbidden army.

In the past 30 years, the city wall has not been expanded, but it has been heightened and thickened, and it is also covered with granite bricks, which is very majestic from a distance.

Although the brick is granite stone, it is also explosives to explode, the crusher is broken, and then cut it piece by piece with the stone water mill, which is very convenient, if it is used pure manpower, it is bound to be a huge project that costs the people and money.

Because the city wall has not expanded, and the space inside the city is limited, now the outside of the city is like the inside of the city, the buildings are lined with people, and the scale is much larger than the inside of the city.

The reason why Bailiyan did not expand the city wall was not only due to the development trend of the city, but also to learn the lessons of the city that year when Duhui City was breached.

The longer the city wall, the more troops need to be garrisoned, although the siege requires five times or even ten times the strength of the defenders, but once it enters the siege war, not to say absolutely, but in most cases the main army or elite army has been annihilated in the field, and defending the city is often helpless, especially the capital, which has been attacked by others under the capital, and it is not far from the country.

The breach of Duhui City was largely due to the fact that the city was too majestic, the siege was too long, and the coalition army was attacked by the blood disease, and the troops were insufficient, so that the Jinxuedi people, who had an absolute advantage in strength, could concentrate their forces to attack only one or two walls, which was enough to defeat the coalition army.

Therefore, it is unrealistic to hold on to a majestic city with a small number of troops, so the size of the city can be moderate, and there is no need to be too extravagant.

Taking a step back, in another 20 to 30 years, under the conditions of modern warfare of the trinity of sea, land and air, the defense and significance of ordinary rammed earth masonry city walls are not very large, but they are still needed at present, especially in the face of the siege of the beastmen, it is much better to have a city wall protection, and it has its necessary practical significance to do appropriate reinforcement and functional expansion.

The mission left the station and took a four-wheeled carriage into the city, Baili Yan also set up a secluded compound to the east of the Zhiguo Pavilion Station, and placed the daughters of Ji Rouer and her family, and the Gongliang family lived in the big house next door, and arranged for Gongliang to enter the palace on the second day, and submitted the credentials on the matter of the Zhiguo Alliance.

Now that the telephone has been called, the practical significance of written documents such as the national letter has been greatly weakened, and as long as the king of Xian wants, he can call Tang Yuanxiang directly and send a telegram anytime and anywhere, and the national letter is at best a text that records the content of negotiations and agreements, and the function of transmitting information is no longer meaningful.

A few days after Gongliangxiu arrived in Chenling, Bai Liyan invited him to the Xianjun shooting range west of Yongxing City to visit the target shooting of the 657 two types of artillery, which gave some atmosphere to the next Huimeng.

After the Battle of Vawei, Zhiguo is now the most populous country, before that it was the eldest grandson, it was the Guardian Country, the eldest grandson can no longer be regarded as a complete prince, the population loss is countless, after the defeat of the Patriotic Kingdom in 650 years, the loss of several counties and millions of people, plus internal problems, the population loss is very large.

After more than ten years of cultivation and recuperation, Zhiguo digested the old land of Sun Guo, and under the economic transfusion of Xianguo, the national strength rebounded rapidly, and the population increased significantly, so Zhiguo's attitude can largely affect the outcome of this alliance.

Bailiyan hopes that Zhiguo can send more troops, and the Jin side will obviously prevaricate and shirk for various reasons, and the Weiguo side is powerless, the economy is too poor, the system is backward, and the population is large, but there are a bunch of internal problems, I am afraid that the battle is not over, and the local rebellion will be made, although Bailiyan also hopes that the Weiguo can collapse, but it is not this time.

As for the other princes, after the Black Turban Rebellion subsided, the Xu State has not eased its strength, and in recent years, its vitality has just recovered, and it can send troops, but it is mainly cavalry, which is not very suitable for frontal combat.

There are few people in the Song Kingdom, and the total economic volume is too small, so it would be good to be able to see the coastline. Qi Guo, Yan Guo, Chen Guo, and Zhao Guo are all countries with small populations, and self-protection is a problem, and it is unrealistic to send troops on a large scale, so how many troops Zhiguo sends and how long it can last is very critical.

In addition, Bailiyan must consider the post-war political structure, and weaken the country through war, which is conducive to the unification of the territory in the future.

Xianguo is already a large industrialized country, basic education is basically perfect, and it will rise rapidly in the ten or twenty years after the war, and the casualties caused by the war will not become a burden under the wave of industrial development and economy.

However, the essence of the Zhiguo is still an agricultural prince, and if one million disabled young adults, one million widows, and one million broken families are added, it will inevitably become a huge financial burden within thirty years.

The deafening sound of artillery was like an earth-shattering thunderbolt, falling on the flat ground dozens of miles away and stirring up bursts of dust, Gongliangxiu was shocked, but he thought of it with Bai Liyan, and he was also thinking about the fate of the princes of various countries after the end of the war.

In the present situation, the armed forces of the Xian State are invincible, and if they want to forcibly unify them, the result is obvious. He was a little absent-minded, Bailiyan saw it in his eyes, so he asked him:

"Brother Gongliang, how powerful is the new artillery?"

"It's extremely powerful, ten gates and twenty gates are so lined up in a line, and I'm afraid that an army of 100,000 people forty miles away will wipe out the whole army."

"That's true, when the armpit landed on the eldest grandson, it was this kind of attention, using the method of field warfare in the Central Plains, he used hundreds of light and heavy artillery pieces of various types to carry out fire strikes on me, and the consequences can be imagined, not to mention 100,000 people, even millions of people will be wiped out.

It's a pity that they miscalculated, and now that they have survived the first four years, the war will be more and more favorable to us in the future. ”

"And how old are these artillery?"

Gongliangxiu asked, Bai Liyan thought carefully for a moment and said:

"With the current production capacity, the two types of artillery will be able to produce more than 200 pieces next year, and if we want more, we can only reduce the production of other artillery pieces and increase the output of this type of artillery. However, in two more years, more large-scale new manufacturing machinery will be put into production, and the number of new manufacturing machines will increase to 300 per year without any problems. ”

"That armpit has a heavy artillery geometry, can it be combated."

"As far as I know, their more than 100,000 men are equipped with about 150 to 200 howitzers with a range of 25 to 28 miles, and according to the information we have so far, their landing force exceeds 1.4 million people, and if they are all in this configuration, it will be at least 2,000 grenades and heavy guns."

"What a disparity!"

Gongliangxiu was taken aback, according to the current production speed, it will take ten years to catch up, where can Zhiguo afford to drag on for ten years.

At this time, Bai Liyan saw what Gongliang Xiu was thinking, and hurriedly said:

"Brother Gongliang can rest assured, this war will be clear in five years."

"But I can drag on for five years!"

Agricultural civilization, national strength is basically the food and basic industrial and commercial output value brought by manpower and land, large-scale all-out war under agricultural civilization, the duration will not be very long, no matter how strong the national strength of the agricultural empire, the high-intensity war will be fought for two years and three years to see the bottom, five years and six years on the verge of bankruptcy abound, even in modern industrial society, three or five years is basically a limit, no matter how long no one can hold on.

But to this day, the great powers including Xianguo, Zhiguo, Jin, and Weiguo have not had substantial war mobilization, but they have been stuck in the quagmire of Changsun for four years.

They are also flesh and blood lives born and raised by their parents, with their own social model and economic chain, Bai Liyan doesn't believe that they can't be beaten or dragged down. If they continue to fight a war that is 10 times more intense for another three years, they will not be able to bear the casualties of 200,000 or 300,000 casualties every year, or even 200,000 deaths.

The essence of war is industrial production, it is the material supply of society, it is the economic cycle, it is the reduction of the average material possession, and when the losses of war are far greater than the gains of war, it is time to stop.

Therefore, Bai Liyan did not intend to really win on the battlefield at all, but to consume them in time and drag them down.

Gongliang Xiu was deeply worried about Baili Yan's plan, he personally felt that he was a prince, but he could not control his own thoughts, the reason was that there was a useless force, there was no force to support it, and no one cared about it no matter how loud it was.

The artillery firing lasted only five minutes, and every shell that was senselessly knocked out, Bai Liyan felt pain in his flesh.
