The main structure of the catapult is made of wood, followed by stonemasons, who are used to process stone.

Most of the trebuchet stones used by the army are stones of roughly the same weight, and the stones are round and square, and they are irregularly shaped.

So this time, Cao Liang proposed to let the stonemason chisel the stone into a stone ball of equal diameter, which is easier to grasp the weight than the stone, and the stone bullet with the same weight can improve the range accuracy and stability of the catapult.

After Cao Liang proposed this plan, he immediately won Ma Jun's recognition and appreciation, although the stone was chiseled into a stone ball, which was time-consuming and laborious, but the contrast effect was quite amazing.

Stone bullets can also be used in city defense and field battles, ordinary stones have edges and corners, and when they are smashed on the ground, they can kill at most a few people, and then the stone will be smashed into the ground.

The biggest feature of the stone bullet is that as long as it is on the hard ground, the huge stone bullet can be rolled for a long distance, and if the slope is relatively large, the round stone bullet can cause a large area of secondary damage.

It is conceivable that the huge stone bullet fell from the sky with a roar, and smashed the enemy soldiers into flesh in an instant, and after it landed, the stone bullets rolled without stopping, and everywhere they went, the enemy soldiers turned on their backs, and it was difficult to parry.

One stone projectile is enough to make the enemy's hands and feet numb, and if hundreds or thousands of stone bullets are fired at the same time, the picture is simply not too beautiful.

To build a catapult, carpenters and stonemasons are used the most, and only a few places will use blacksmiths, and Cao Liang asked the cow steward to find several blacksmiths at once, which is obviously a bit wasteful.

Even Ma Jun clearly told Duo and him that he didn't need so many blacksmiths.

Of course, Cao Liang doesn't feel wasted, a real blacksmith, he still lacks too much.

But the repeater is also a shady thing, and the repeater is different from the catapult, and few people can recognize that it is a catapult until the final assembly is completed.

And the crossbow, the recognition is very low, even ordinary people, will see that this is a crossbow, although the lethality is unknown, but in terms of technology, it is enough to surpass the ordinary crossbow.

Therefore, the blacksmith who makes iron, Cao Liang insists on using a blacksmith trusted by Hondazhuang, and the purpose of this is the same, that is, to prevent the leakage of news, once the news is leaked, the consequences are unimaginable.

If you want to form combat effectiveness, the number of crossbows is naturally indispensable, and at the very least, you must equip a few hundred-man teams to form a scale on the battlefield.

Cao Liang decided to build some of the repeaters first, after all, this thing is expensive, it is all made of stainless steel, and even the arrow clusters are made of iron, which consumes a lot of iron.

In this era, salt and iron were monopolized, salt was related to the lives of thousands of households, and iron was to prevent individuals from possessing weapons.

Although Cao Fu is strong, if he really wants to build a repeater regardless of the cost, he will definitely be stretched, don't you see that the face of the cow steward is almost green?

This made Cao Liang sigh, although the weapon is good, it is too good to burn money, and this is just the development of two weapons, if it is really a team of thousands of people, it is not as simple as burning money.

To be honest, Cao Liang still admires the Sima family, in terms of family status, the Sima family still can't be compared with the Yingchuan Xun family, the Chen family and the Qinghe Cui family, the consequence of the lack of solid background is that the property is insufficient, and if you want to feed the dead of 3,000 people, it is far from enough to rely on Sima Yi's fortune alone.

Cultivating the dead is a particularly money-burning project, the dead soldiers have to eat, drink and train, and the weapons and armor used must be excellent, and all of them have to cost money.

It seems that the Sima family has a way of making money, at least it is not easy to feed so many dead people, and it is more than ten years to raise it, and without a huge capital chain to guarantee it, it will collapse in minutes.

But where did the Sima family's wealth come from?

Cao Liang really didn't know this, so he could only inquire slowly.

If you can find a way to cut off the Sima family's financial route, I am afraid it will be the biggest blow to the Sima family.

It was getting late, and after Cao Liang settled Ma Jun, he rushed back to Luoyang City with Fang Bu and Afu Agui.

Although the sunset has arrived and the sky is about to twilight, it has not reduced the flow of people in the slightest.

In particular, Dongda City and Xida City are a paradise for tourists, and the crowds here are shoulder to shoulder, bustling, and a prosperous scene.

Cao Liang is from the Qingyang Gate in the east of Luoyang, when he came back, he also walked to the Qingyang Gate, at this time he was catching up with the big set, the crowd was surging, they could not gallop quickly, they could only follow the flow of people slowly.

was walking slowly, suddenly there was a commotion in front, there were many onlookers, Cao Liang was very curious, so he got off the horse and squeezed into the crowd, ready to take a look.

Fang Bu didn't say a word, and followed Cao Liang closely, protecting him left and right. Ah Fu and Ah Gui each led two horses, so they could only wait outside and could not go in.

Cao Liang squeezed in to take a look, but it was a big man with thick eyebrows and big eyes, and good facial features were selling a few swords there, and he shouted loudly: "In Xia Shibao, the Bohai people's clan, the exile in Beijing, cast iron and sell swords for a living, and now cast a sword, and want to sell it to those who know the sword, all the fathers and villagers, I don't know if you intend to buy swords?" ”

Stonebud?

Cao Liang groaned secretly, he actually had the same name as the founding hero of the Western Jin Dynasty, the general of the expedition to the east, and the great Sima Shibao? Oh, no, I remember that Shi Bao was born in a slight cold, and when he was young, he sold iron for a living, and later met Sima Yi, appreciated his talent, and then entered the official career.

Maxima is often there, Bole is not often, Shi Bud is a talent, this is no doubt, but before he met Sima Yi, he could only live on the streets of Luoyang to sell iron, no one appreciated, if there is no Sima Yi's support, maybe Shi Bud can only be destined to be a skilled blacksmith in this life, and the Western Jin Dynasty will have one less founding general.

It seems that Shi Bao has not yet met his fate Bole Sima Yi, this golden opportunity, how can Cao Liang miss it, he stepped forward quickly and came to Shi Bao's stall.

Although Shi Bao shouted loudly there, there were many onlookers, pointing and pointing, but none of them were willing to pay for a sword.

Shi Bud is also very helpless, if he can't open today, he can't pay the rent, and he will be swept out of the house by the landlord, so he can only sleep on the street.

However, Shi Bao's swords have just been beaten, the sword body is jet black, there is no hilt and decoration, and the quality is far from the swords in those shops, so naturally no one cares about it.
