readx;? In order to reclaim 5 million mu of cultivated land north of Hengshan City, they would have to move in at least 200,000 young and strong laborers, plus the old and weak women and children who were dragging their families, and at that time they would need to move in about 500,000 or 600,000 people to meet the requirements.

In addition, the horse farm, the substitute wood yard, the quarry, the iron mine, the copper mine, the iron smelter, and many war weapons, the casting yard of loading vehicles, and the manufacturing workshop, senior craftsmen can all be transferred from Liquan, but they also need nearly 200,000 young and strong laborers to meet the requirements put forward by Chen Hai.

Moreover, these young and strong laborers are more demanding than the labor force of reclamation and cultivation, and they need to be able to reach the level of junior craftsmen through training, where do these young and strong laborers come from?

Hengshan is not as able to absorb displaced people from all directions after the war, and most of the territory of Tianshui County is under the stable rule of the Liao, Wu, and Zhou clans, and the three clans will never allow the subjects under their rule to flow into Hengshan Mansion on a large scale.

In addition, the ordinary people have relocated to their land, and as long as there is no major famine or war, who wants to leave their homes? Let alone move to the north of the Hengshan defense line, which is directly threatened by the demons, to reclaim the land?

The smelting of refined iron and refined copper is not an exaggeration to achieve this goal in five years, after all, in the northwest foothills of Qintong Mountain, there will be no shortage of ordinary copper and iron ore veins, as long as enough manpower can be organized, copper and iron ore can be mined to smelt under the mountain.

And if Chen Haizhen wants to build a strong defense line in Yuchengling, the consumption of basic copper and iron is naturally astronomical, and the consumption of millions or tens of millions of catties every year is the norm.

The production requirements of all types of Tianji chariots are not exaggerated, and when the time comes, you can consider moving the chariot workshop of the Tianji Academy Palace in Liquan to Hengshan;

However, the goal of 2,000 loading trucks per year, 10,000 individual crossbows, and 1 million crossbow arrows for individual crossbows is too exaggerated.

At this time, the Tianji Academy Palace can get two million catties of quenched gold iron from Liquan every year, and can secretly obtain an additional 300,000 catties of high-quality quenched iron from Lucheng, which is a considerable number, but these are used to make the existing Tianji chariot and Tianji crossbow and other combat weapons are exhausted, and there is no more quenched iron to realize Chen Hai's grand plan.

Even if Lucheng can increase the production of quenched iron, but from Lucheng, it has to pass through Hexi, and Hexi has actually always controlled the total amount of quenched iron obtained by the Tianji Academy Palace from Lucheng, intentionally or unintentionally.

Hexi will not tear his face with the Tianji Academy Palace at this time, so he will not directly block the caravan of the Tianji Academy Palace from borrowing from Hexi, but if you think that the caravan of the Tianji Academy Palace can unscrupulously transport a large amount of quenched iron from Lucheng into Qintong Mountain through Hexi, it is a big mistake.

Although the two families did not talk about this aspect, Su Yuan estimated that the Tianji Academy Palace would transport 500,000 catties of high-quality quenched iron from Lucheng every year, which should be the limit that the Dong family could bear.

Unless the Yokoyama Line can reproduce a new quenched gold placer.

Although Su Yuan and the others did not thoroughly understand the formation principle of quenched gold placer ore, but to the north of Hengshan City, it did not look like there was a quenched gold placer mine.

In addition, the core components of individual crossbows and loading vehicles, even if they are simple versions of the arrow array box or wind array power box, all belong to the category of Xuan-level low-grade magic weapons.

The other parts are easy to cast, but the simple version of the arrow array box or the wind array case has to refine a total of more than 12,000 sets every year, which is also a terrifying task.

Huang Shuang, Su Yuan, Sun Gan, and Zhang Xiong were all dumbfounded when they got Chen Hai's catalog, and they didn't know what to say.

********************

"There is still room for further improvement in this individual crossbow, but this time the improvement is not in the arrow box, but in the crossbow structure and crossbow arrows. Although the casting of crossbow arrows has become a bit more complicated, the weight of a single crossbow arrow can be controlled to less than five taels. Chen Hai said.

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

"Yes, even the tail part is enough to use ninth-level quenched iron......," Chen Hai said, showing the new crossbow structure and the secret map of the new crossbow arrow from the storage ring to Su Yuan and Zhang Xiong.

In the past two or three years, Chen Hai has been thinking that the portable individual crossbow can completely replace the traditional bow and crossbow.

At present, with the efforts of many craftsmen, the Tianji Palace has developed a single crossbow with a total weight of 60 catties, and the effective range is controlled at 500 steps, but to ensure the shooting power, it is necessary to ensure that any general can carry enough crossbow arrows to continue to fight on the battlefield.

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

Although the short crossbow arrow can be recovered, after being shot from the crossbow chamber, the sharpest and thinnest arrow clusters and edged parts will be seriously deformed, and the range and shooting accuracy can no longer be controlled, and they need to be recast after returning to the furnace.

In this process, not to mention the additional labor, the quenched iron itself will also have an additional consumption of two or three percent.

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

Because Chen Hai had always intended to control a large amount of heavenly machine weapons and quenched iron into Hechuan County, and the actual supply of quenched iron materials in Hexi was far from that of other border counties, this gave Hexi the opportunity to capture the Wenhubu defense line at once, and did not give Hexiang's army a chance to form a tug-of-war.

Because of this, there was a huge disparity in strength between the two sides, so the millions of quenching arrows that Hexi had reserved in the previous years were enough in this war.

In order to suppress Hexi's ambitions, and also to tell Zhao Zhong and Wen Boyuan that the Tianji Academy Palace would never surrender to Hexi, and would never collude with the Dong family to seize Tianshui County.

If Chen Hai didn't do this, the Miao, Yue and other clans, as well as the Yanran Palace and the Jingjun Zonglord, would also do the same, after all, no one wanted to see the possibility of Hexi taking Qintong Mountain; in fact, after Hexi controlled the entire territory of Hechuan County, someone had already secretly supplied the Tianji Repeater Crossbow to the Musashi army.

With both sides equipped with a certain number of heavenly crossbows and evenly matched, the form of the war naturally changed dramatically again, and both sides had millions of quenching arrows in reserve, which might only be enough to consume a conventional war.

From then on, the two sides are likely to turn into a war that no one can afford to consume.

The cost of quenched iron is still too high.

Of course, Hexi can obtain an additional nearly two million catties of eighth-level quenched gold iron from Lucheng every year, and the advantage is still very obvious, but at this time, it is also necessary to pause and rebuild momentum, so that one day it can break through the Meishan defense line in one fell swoop, and it is easy not to give the Musashi army a chance to entangle into a tug-of-war.

In the final analysis, it is also the quenched crossbow arrows that cannot withstand long-term consumption.

At this time, Chen Hai directly reduced the demand for quenched iron for crossbow arrows to four to one-fifth of the previous one by changing the crossbow structure, which was naturally jaw-dropping.

"How did the semi-closed crossbow slot become a fully enclosed crossbow, and how did the special crossbow arrows become so short and so weird?" The semi-enclosed crossbow slot of the individual battle crossbow became a fully enclosed crossbow, and everyone didn't care about it, but seeing the strange crossbow arrows drawn on the secret map, Su Yuan and the others were startled, this structure was too different from the crossbow arrows that the Tianji Academy Palace was diligently studying at this time.

"Or it's more reasonable to call a crossbow" Chen Hai said with a smile: "I work in Lianshui, but I haven't been idle, try to make a single crossbow, you can test it......" He took out a five-foot-long individual crossbow from the storage ring and handed it to Su Yuan for them to test fire.

Whether it is a heavenly machine crossbow or a single golden halberd crossbow, the core is still in the arrow rune array, which can produce extremely fierce restraint energy in a very small space, and shoot sharp metal arrows. During this period of time, the Tianji Academy Palace improved the forbidden structure of the arrow rune array, making the restraint energy generated by the arrow rune array shorter, stronger, and more stable in directionality, but the thinking still stayed on the traditional bow and crossbow structure, and only thought about ensuring the balance and penetration of the crossbow arrows after shooting, and the arrow shaft was cast long and narrow.

However, Chen Hai has always understood Yanzhou's arrow array box as an electromagnetic gun or electromagnetic cannon on the earth, and the balance and drilling penetration of crossbow arrows after shooting can be guaranteed by rifling, removing the long arrow shaft and the tail wing with a complex structure, the crossbow arrow will actually become a crossbow bullet, and the consumption of quenched iron can be greatly reduced.

In fact, Chen Hai had already thought of this problem, and he also knew on earth that the bullet produced high rotation through rifling and maintained accuracy, but the problem was that he also didn't know how the spiral rifling inside the crossbow was carved out quickly and accurately.

Chen Hai has only recently thought through this issue.

And if you think about this problem thoroughly, you can only become a reality if you can equip the Longxiang battalion with individual crossbows in batches.

To the north of Hengshan, many rivers will change once in a few years, and there is no condition for the formation of quenched gold placer mines, but if Chen Hai wants to achieve the goal he has set, what he hopes is not to monopolize the quenched gold placer mines, but to continuously introduce more and more advanced puppet weapons, so that the families can drive cattle, horses, pigs, sheep, gold, iron, strange stones and other materials to trade with them.

Su Yuan personally picked up the individual crossbow that Chen Hai had tried to make, shot at the target outside the city, and hit a waterfowl that flew up from the water four hundred paces away. This waterfowl is naturally not a spirit bird, it is like a goose, it is very clumsy to fly, and it is torn to pieces by the crossbow shot in mid-air.

Zhang Xiong, Huang Shuang and others could accurately estimate how powerful this crossbow projectile would be after it was fired, and they were all happy.

"This kind of individual crossbow, we can give priority to the supply of Tianshui Army, and other conditions can be discussed. Chen Hai said.

At this time, everyone suddenly realized that the Wu, Zhou, and Liao clans would not easily let the Tianji Academy Palace go to their territory to recruit young and strong laborers, but what if they traded with them with a batch of individual crossbows every once in a while? They could not directly smelt a large amount of quenched iron in Hengshan, but what if the Miao, Yue, and Dong clans also needed to equip this kind of individual crossbow?

"Once it spreads out too early, what if other families copy it in large quantities?" Su Yuan asked.

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

Individual crossbows are to be equipped in batches, even if they are not sold to other families, even if they are stolen or robbed from the Longxiang battalion, they can get individual crossbows, and then it is not difficult to crack the internal structure that is not complicated, and senior craftsmen can manually engrave rifling directly in the closed crossbow chamber.

As long as there are senior craftsmen with the cultivation of the Spiritual Realm, the perception of the six senses and the stability of the hands and eyes are enough for them to carve very accurate rifling, and the key issue is the output.

Tianshui County has elites who have the foundation of cultivating in the spiritual realm, and there may be one or two thousand people in total, which is the cornerstone of Tianshui County's military and political organs.

As long as Chen Hai temporarily ensures that the Lache method is not leaked, even if other families get the picture scroll of the individual battle crossbow and can copy it immediately, the output and cost are far from being comparable to the Tianji Academy.
