Such an epoch-making weapon, just like this, is still in a small border village, which makes Han Qi a little unbelievable, even if this person is Sun Ji.

But no matter how hard he couldn't believe it, this weapon was placed in front of him, and he had seen the longbow, not the feeling of a composite bow, the bow body was a kind of wood, he didn't know what elm was, but what kind of wood could Miaojiazhuang get.

Both direct and circumstantial evidence prove that this bow is not much expensive.

Han Qi even directly thought of the possibility of the forbidden army of the Northern Song Dynasty, and even all the armies of the Northern Song Dynasty, changing this bow.

All the materials of this bow have a huge base, and some ordinary wood can be made, of course, this needs to be studied to see which kind of wood is suitable, and there are many types of hardwood.

But even if it is purely limited to elms, this number is very large, at least, 1 million is absolutely there, and there are at least 1 million elms in the whole north, and if other hardwoods can be obtained, it will be even more.

Even if it is not enough, it doesn't matter, according to the requirements of the longbow, five or seven years is enough, and a weapon is integrated into the Northern Song Dynasty Forbidden Army, it takes time, and five or seven years is just right to integrate.

Therefore, even if you start large-scale cultivation, that is, wait 10 years of work, and the raw materials will be ready.

The bow body is the biggest problem, because of the need for wood, the most critical bowstring of the short bow in the past, but it is easier to solve, the silkworm cocoon is the most thing in the Northern Song Dynasty, the annual output of silk, tens of millions of horses, silkworm cocoons are even more than countable, the bowstring for silkworm cocoons is not high, waste can be, which has a larger sea of raw materials.

Coupled with the fact that so many carpenters in the entire Northern Song Dynasty used other simplest bows and arrows, one-tenth or even one-twentieth of the price, but made similar bows, such a thing was a temptation that was difficult to refuse for the Northern Song Dynasty.

Even if the price of the longbow is about the same as that of an ordinary short bow, Han Qi is willing to change his clothes, the short bow is not only expensive in itself, but also the maintenance cost is quite high.

Even if there is no war, after a few years, it will have to be replaced, so the annual maintenance cost is an astronomical amount, and Han Qi knows that this number is 2 million.

That's right, at present, the Northern Song Dynasty has all kinds of short bows, about 1.5 million, which need to be replaced every year, accounting for about one-tenth, 150,000, according to the average number of 7 guan, this alone is 1 million, and other repairs, replacements, and even maintenance occupy another 1 million guan.

This is already saving and saving data, what if it is replaced by long-term workers? Even if this possession is doubled, 3 million longbows, which is already the number of archers who have expanded several times, and the new ones are completely used, the total cost is only 600,000 guan, and with one-fifth of the maintenance cost, the entire army can be saved by 1.9 million guan, which is a terrifying and suffocating number.

The only weakness of the longbow is on the arrow, the consumption is slightly larger, the rate of fire of the longbow is very fast, but the longarrow is also very low compared to the bow, the current price of the longarrow is about 10 Wen, even according to the 10 arrows used by a bow every year, it is only about 0.1 guan, and the annual consumption is 300,000 guan.

Don't think that the average bow is low at 10 arrows per year, that's already very high, the average arrow, mainly iron, as long as you don't shoot at the harder substance, the arrow will not be broken, at most the arrow body and tail are damaged.

Even in training and fighting, arrows are broken, arrows are broken, and they can be recycled, and the unique property of iron is that even if it is damaged and destroyed, as long as the weight is not reduced much, after re-casting, it can still be manufactured, and it may pay a little time and labor cost, but the cost of regaining iron is much lower.

Recycling and reuse, which saves a lot of costs, the annual consumption of arrows is quite limited, unless it is a border operation, pure consumption, taken by the enemy, or wasted in the enemy-occupied area, that is a net loss, but how much can such a battle be.

From the beginning of the alliance of the Yuanyuan, the Northern Song Dynasty rarely fought across the border, in the northwest, in most cases, it was passively beaten, the geographical location of the northwest, after the battle of the founding of the Western Xia, had enough geographical advantages, unless the Northern Song Dynasty was a large-scale mobilization, there was no way to attack the territory of the Western Xia.

This is also the reason why the longbow consumes a lot of bows and arrows, and Han Qi doesn't care about it, a strong desire rises in Han Qi's heart, change, must change.

Han Qi knew very well that for ordnance, even a one-tenth reduction was enough to move the entire military, because the number was huge to 100,000, or even 1 million, one-tenth was quite terrifying, and for the short bow, the average cost was 7 guan, and if it was reduced by one percent, it would be 700 wen, and with a total of 1.5 million, this could be one million guan.

Not to mention, the reduction of the longbow is not one percent, but ninety percent, and this number may climb to the level of tens of millions.

The scholar is ashamed to talk about money, but when he really does the high-ranking officials of the court and worries about the entire court, money really has to be discussed, and it is difficult for a good woman to cook without rice.

Before the change, when the military didn't worry about money, it always thought about performance, but recently, since the beginning of the Northwest War, the military's life has been tight, and the entire Northwest is like a bottomless pit, and all the little things that have accumulated have been ruthlessly swallowed by it.

Not to mention the million-level level, even if it is 100,000 guan, it is enough to make him a deputy privy councillor pay attention, not to mention the million-level level, or even the ten-million-level level, the three envoys and the privy envoy will be alarmed.

Of course, this replacement, not a direct comprehensive replacement, that is too wasteful, a year to replace 10 percent, ten years to complete the replacement, to achieve a comprehensive reformation, new equipment and new formation is wrong, all use this, for the military, the annual cost savings, is also very amazing, the initial may only be a few hundred thousand, more than 1 million in the later stage.

It can almost be replaced, not to mention, his power is so great, his training is so economical, maybe, as long as he persists for a year or two, the number of archers in the Northern Song Dynasty forbidden army will be doubled, and this temptation is huge.

The longbow has passed the test, and such an excellent weapon is so easy to use, I am afraid it is the blessing of Miaojiazhuang.

But the surprise has not disappeared, and then, Sun Ji began to introduce the fortress again with the help of the longbow posture, which was two completely different concepts before and now.

Sun Ji focused on the fortress, in addition to the height, there are other aspects of the arrangement, these arrangements, so that Han Qi, who is accustomed to all kinds of excellent defense, is also a little moved, if the longbow team suppressed the rebels, is a good start, at most, caused hundreds of archers casualties, then the fortress is the finishing touch, his battle above, decided the victory.

In particular, Sun Ji said that under the premise of losing the first battle, the rebels chose the method of personnel impact, even if he did not have a good solution to this situation, he could only think of one, that is, indiscriminate attacks, killing those people, although the killing was a little higher, but it was better than being breached.

If it is said that it is an enemy, who has just been trained, and under the premise of being brave in the fortress, he can still fight, but in the face of unarmed civilians, or living around, and maybe even seeing objects every day, can he do it?

Han Qi also felt that this was a terrible test, but on the contrary, Miaojiazhuang solved it, and on the premise of not using indiscriminate attacks, Han Qi glanced at this point.

I don't know if it's intentional or unintentional, Sun Ji mentioned the tree cannon without an end, maybe in his feeling, the tree cannon is a bit chicken, yes, it takes a lot of preparation, and if it is used more times, it will blow up the chamber.

In the final battle, at least 3 tree cannons were blown up, but fortunately, the thickness of the tree cannons was larger, and they were also hooped with iron hoops, and the cannon body was only cracked, not exploded in four blows, but it was still quite scary.

Sun Ji didn't have a key introduction, and Han Qi didn't care, he just felt that this disposable weapon was a bit lethal, but compared to the longbow and the fortress itself, this tree cannon was not eye-catching, and the germ of a hot weapon was just missed.

Zhao Xin didn't care at all, the tree cannon was just a choice in desperation, his biggest weakness was really close to one-time, maybe less, at most thirty or forty times, and a battle might be used up.

And the rate of fire is slow, slow reloading is a hard wound, wood is wood, under the action of gunpowder, it will burn, after a launch, it must be cleaned and cooled, otherwise it will explode and burn if it is loaded into a medicine bag.

The future development is still the most suitable metal weapon, Zhao Xin is a traverser, and he also has a card system against the sky, as long as he is given a year or two of development time, qualified iron, and even steel can be made, and it is not a difficult thing to make a cannon with iron molds, and the era of firearms is bound to come.

A weapon that may change the strength of the fortress has been leaked out like this, but even so, the combination of the fortress and the longbow is also insolvable, and the role of the tree cannon is more about large-scale killing and cleaning during intensive sieges, but is it really useful.

This is the icing on the cake, and the strength of the fortress and longbow defense is high enough, and these two solve all problems.

Han Qi had actually been overwhelmed by the defense of the fortress, and what he was struggling with now was that the cost of the fortress, it seemed that this fortress with such a high defensive strength must not be simple, maybe it would be very expensive.

That's right, even if you are a privy deputy, he is trapped by money, money, this thing is really the most troublesome.
