Chapter 371

If they want to reclaim five million mu of arable land north of Hengshan City, they need to move in at least 200000 young and strong workers, plus the old, weak women and children who drag their families with them. At that time, they need to move in almost five or six million people to meet their requirements.

In addition, senior craftsmen can all be transferred from Liquan in horse farms, Daimu farms, quarries, iron mines, copper mines, various iron smelting farms, as well as foundry and manufacturing workshops for many war equipment and loading vehicles, but it also requires nearly 200000 young and strong labor to meet the requirements put forward by Chen Hai.

Moreover, the requirements of these young and strong workers are higher than those for reclamation and cultivation. They need to be trained to reach the level of primary craftsmen. Where do these young and strong workers come from?

Hengshan is no better than Lianshui Prefecture after the war. Most areas of Tianshui county are under the stable rule of Liao, Wu and Wednesday. The three ethnic groups will never allow the affiliated people to flow into Hengshan Prefecture on a large scale.

In addition, ordinary people have moved back in peace. As long as there is no major famine and war, who is willing to leave their homes? What's more, they moved to the north of Hengshan defense line directly threatened by demons and barbarians to reclaim land?

The smelting of refined iron and copper is not an exaggeration to achieve this goal in five years. After all, there are no fewer ordinary copper and iron ore veins in the mountains at the north foot of Qintong Shanxi. As long as enough manpower can be organized to mine copper and iron ore to smelt at the foot of the mountain.

If Chen Haizhen wants to build a strong defense line in yuchengling, the consumption of basic copper and iron is astronomical, and the consumption of millions of kilograms and tens of millions of kilograms every year is normal.

The production requirements of various types of Tianji chariots are not exaggerated. At that time, we can consider moving the chariot workshop of Tianji academy palace in Liquan to Hengshan; The main patriarchal clans in Yanzhou previously chose to purchase the manufacturing drawings of Tianji chariots directly from Tianji academy palace. At this time, they can manufacture all kinds of Tianji chariots. The chariot workshop of Tianji academy Palace should also serve Longxiang camp.

However, the goal of an annual output of 2000 loading vehicles, 10000 individual crossbows and one million special crossbows and arrows is too exaggerated.

At this time, Tianji academy palace can get 2 million jin of quenched gold and iron from Liquan every year, and can secretly obtain another 300000 Jin of high-quality quenched gold and iron from Lucheng. This is a considerable figure, but these are used up in the manufacturing of existing Tianji chariots, Tianji war crossbows and other war equipment, so it can't squeeze out more quenched gold and iron to realize Chen Hai's grand plan.

Even though Lucheng can increase the output of quenched gold and iron, when you come from Lucheng, you have to pass through Hexi. In fact, Hexi has always intentionally or unintentionally controlled the total amount of quenched gold and iron obtained by Tianji school palace from Lucheng.

Hexi will not break face with Tianji school Palace at this time, so it will not directly prevent the caravan of Tianji school palace from passing through Hexi. However, it would be a big mistake to think that the caravan of Tianji school palace can recklessly transport a large number of quenched gold and iron from Lucheng into qintongshan through Hexi.

Although neither of the two families spoke about this, Su Yuan estimated that the annual transportation of 500000 kilograms of high-quality quenched gold and iron from Lucheng by Tianji school Palace should be the limit that Dong's family should bear.

Unless the Hengshan defense line can find new quenched gold placers.

Although Suyuan and others did not fully understand the formation principle of quenched gold placer, it did not look like quenched gold placer to the north of Hengshan city.

In addition, the core components of individual combat crossbow and loading vehicle, even the simple arrow array box or wind array power box, belong to the category of mysterious inferior magic weapons.

Other parts are easy to cast, but the simple version of arrow array box or wind array motor car box needs to refine more than 12000 sets every year, which is also a terrible task.

Huang Shuang, Su Yuan, sun Gan and Zhang Xiong were stunned when they got Chen Hai's catalogue. They didn't know what to say.

"This is an individual combat crossbow. There is still room for further improvement, but this time the improvement is not in the arrow array box, but in the crossbow bore structure and crossbow arrows. Although the casting of crossbow arrows has become more complex, the weight of a single crossbow arrow can be controlled below 50 Liang," Chen Hai said.

"The decline is so high?" Su Yuan and Zhang Xiong were quite surprised.

"Yes, even nine levels of quenched gold and iron are enough for the tail..." Chen Hai said. From the storage ring, he showed Su Yuan and Zhang Xiong the new crossbow chamber structure and the secret drawing of the new crossbow and arrow.

Over the past two or three years, Chen Hai has been thinking about developing portable individual combat crossbow, which can completely replace the traditional crossbow.

At present, thanks to the efforts of many craftsmen, the total weight of the individual combat crossbow developed by Tianji school palace has been reduced to 60 kg, and the effective range is controlled at 500 steps. However, to ensure the shooting power and ensure that any general and soldier can carry enough crossbows and arrows to continue to fight on the battlefield, Tianji school palace is a special short arrow with a length of three inches made of Grade 8 quenched gold iron. Even so, Each short crossbow still weighs more than two kilograms.

This makes it unrealistic to equip individual crossbows on a large scale in the army.

Although the short crossbow can be recycled, after being shot from the crossbow chamber, the sharpest and thinnest arrow clusters and edges will be seriously deformed. The range and shooting accuracy can no longer be controlled, and it needs to be recast after being returned to the furnace.

In this process, not to mention the additional labor consumption, the quenched gold iron itself will also consume an additional 23%.

Hexi's capture of Hechuan county is a fundamental change in the balance of power between the two sides over the years.

Chen Hai has always intended to control a large number of heavenly weapons and quenched iron flowing into Hechuan County, and the actual supply of quenched iron in Hexi is far more powerful than that in other border counties, which gives Hexi the opportunity to capture the wenhubu defense line at once and does not give the crane Xiang army the opportunity to form a tug of war.

Therefore, the strength of the two sides is very different, so the millions of quenched gold arrows stored in Hexi a few years ago are still enough in this war.

In order to suppress the ambition of Hexi, and also to tell Zhao Zhong and Wen Boyuan that Tianji academy will never be attached to Hexi and will never collude with Dong to seize Tianshui County, Chen Hai led Longxiang camp to move to Hengshan. At the same time, it is to release the supply restrictions of Tianji crossbow and Tianji chariot on the Musashi army.

If Chen Hai doesn't do this, Miao, Yue and other ethnic groups, Yanran palace and Jingjun Zong valve will do the same. After all, no one wants to see the possibility of seizing qintongshan in Hexi; In fact, after Hexi controlled the whole territory of Hechuan County, someone had secretly supplied Tianji crossbows to the Tibetan army.

When both sides are equipped with a certain Tianji crossbow and are evenly matched, the form of war naturally changes again; Both sides reserve millions of quenched gold arrows, which may only be enough for the consumption of a conventional war.

From then on, the two sides with equal strength are likely to evolve into a war that no one can afford.

The cost of quenching gold and iron is still too high.

Of course, Hexi can obtain nearly two million kilograms of eight grade quenched gold and iron from Lucheng every year. The advantage is still very obvious, but at this time, it also needs to pause and get ready again, so that one day it can break through the Meishan defense line at one stroke, and it is easy not to give the Tibetan army the opportunity to entangle into a seesaw battle.

In the final analysis, it is also the quenched gold crossbow that can not withstand long-term consumption.

At this time, by changing the structure of the crossbow chamber, Chen Hai directly reduced the demand for quenched gold and iron of the crossbow to one fourth to one fifth of the previous one. This change is naturally amazing.

"How did the semi closed crossbow slot become a fully closed crossbow chamber; how did the special crossbow become so short and so strange?" everyone didn't care that the semi closed crossbow slot of the individual combat crossbow became a fully closed crossbow chamber, but Su Yuan and others were shocked to see the strange crossbow drawn on the secret map, This structure is much different from the crossbow and arrow studied by Tianji Academy at this time.

"Or it's more reasonable to call the crossbow bullet," Chen Hai said with a smile. "I work in Lianshui, but I don't have time to trial produce a single soldier crossbow. You can test fire..." he took out a five foot long single soldier crossbow from the storage ring and handed it to Su Yuan for test firing.

Whether it's a Tianji crossbow or a single golden halberd crossbow, the core is still in the arrow Rune array. It can produce extremely fierce binding gas force in a very narrow space and shoot sharp metal arrows. During this period of time, Tianji school palace improved the forbidden structure of the arrow Rune array, making the binding gas generated by the arrow Rune array shorter, stronger and more stable in direction. However, its thinking still stays on the traditional bow and crossbow structure, and only wants to ensure the balance and penetration force of the crossbow after shooting, and the arrow rod is cast narrow and long.

However, Chen Hai has always understood the arrow array box in Yanzhou as an electromagnetic gun or electromagnetic gun on earth. The balance and penetration force of the crossbow after shooting can be guaranteed by rifling. Removing the long arrow rod and complex tail wing, the crossbow will actually become a crossbow bullet, and the consumption of quenched gold and iron can be greatly reduced.

In fact, Chen Hai has long thought of this problem. He also knows that bullets rotate at high speed through rifling and maintain accuracy on earth, but the problem is that he doesn't know how the spiral rifling inside the crossbow chamber is carved quickly and accurately.

Chen Hai has only recently thought through this problem.

Only by thinking through this problem can individual crossbows be equipped with Longxiang camp in batches.

To the north of Hengshan, many rivers will change once in a few years. There is no condition for quenching gold placer. However, in order to achieve his goal, Chen Hai hopes not to monopolize quenching gold placer, but to continuously launch more and more advanced mechanism puppet weapons, so that everyone can drive cattle, horses, pigs and sheep, carry gold, iron, strange stones and other materials to trade with them.

Su Yuan personally picked up the man-made crossbow produced by Chen Hai, shot at the target outside the city and hit a waterfowl flying from the water four hundred steps away. Naturally, this waterfowl is not a spirit bird. It is shaped like a goose. It is very clumsy to fly. It is torn to pieces by the crossbow shot in mid air.

Zhang Xiong, Huang Shuang and others could accurately estimate the penetration power of the crossbow after it was ejected, and they all looked happy.

"We can give priority to the supply of this single soldier crossbow to the Tianshui army, and other conditions can be discussed," Chen Hai said.

It dawned on everyone at this time that the Wu, Zhou and Liao nationalities would not easily send the Tianji school palace to their territory to recruit young and strong workers, but what if they took a batch of individual crossbows to trade with them every once in a while? They can't directly smelt a large amount of gold and iron in Hengshan, but what if the Miao, Yue and Dong families also need to be equipped with this single soldier crossbow?

"Once it is spread out too early, what about a large number of copies from other families?" Su Yuan asked.

"It doesn't matter," Chen Hai said with a smile.

The individual combat crossbow needs to be equipped in batches. Even if it is not sold to other families, even if they steal or rob it from Longxiang camp, it is not difficult to get the individual combat crossbow, and then crack the internal uncomplicated structure. The senior craftsman can manually carve rifling directly in the closed crossbow chamber.

As long as there is a senior craftsman with the foundation of spiritual cultivation, the six senses and the stability of hands and eyes are enough to make them carve very accurate rifling. The key problem is the output.

Tianshui county has elites with the foundation of spiritual cultivation, which may add up to one or two thousand people. They are the cornerstone of Tianshui county's military and political organs. If they don't master certain skills, how many people can Tianshui County draw out to mechanically re carve rifling?

As long as Chen Hai temporarily guarantees that the pulling and cutting method will not be disclosed, even if other families get the picture scroll of the individual combat crossbow and can copy it immediately, the output and cost are far from comparable to the Tianji Academy.
