This torsional stone throwing machine consists of a sturdy and heavy rectangular frame on the ground, an upright catapult rod, and two sturdy pillars topped by beams. Pen? Interesting? Pavilion wWw. ｂiquge。 The lower end of the info ejection rod is inserted into a tightly twisted horizontal rope that is tied to the ends of the rectangular frame, just below the support frame. Usually the rope makes the ejection rod tightly against the beam on the support frame. The top of the ejection rod is usually made in the shape of a spoon, and sometimes a leather pouch is attached to the top of the ejection rod.

When ejecting, the ejection lever is pulled to a near-horizontal position with a winch, and then a rock or other type of projectile is placed in a "spoon" or leather bullet bag. When the winch rope is loosened with the trigger device, the ejection lever returns to a vertical position with great force and collides with the beam, generating an inertial force that catapults the projectile body to the target in an arc track. This kind of stone throwing machine is a powerful siege weapon, it can eject more than 100 catties of stones at a distance of 7 or 800 steps, and of course, it can also shoot smaller stones like hailstones.

Large ballistas were powerful, but they were also bulky and slow to fire, so they were only equipped with three per army. Zhao Yu originally wanted to use it as a killer weapon at the most critical time, but now that the enemy army has come out of the coverage of rockets, he rushed to the front of the formation to assemble and force a breakthrough with a shield, and this large ballista came in handy at this time.

'Bang, bang, ......bang' The stones that fell from the sky smashed on the shields held high by the enemy soldiers, and the shields based on hardwood and cowhide blocked the arrows, but they could not stop the stones falling from the sky, and the shields were smashed and smashed on the bodies of those enemy soldiers, and they were either killed or injured under the huge inertia. The three large ballistas fired hundreds of stones quickly, instantly disrupting the formation of the Yuan army that had just assembled.

"The goal remains the same, keep shooting!" Zhao Yu saw that the Yuan soldiers were severely damaged, but they had not yet lost the ability to attack, so he ordered again.

When the Yuan army, under the orders of the officers, braved the rain of arrows and small ballistas, and prepared to attack again, another wave of stone bullets fell from the sky, throwing them into chaos again. It was no longer possible for them to assemble again for the third time, and the soldiers had been frightened by the repeated blows, and the officers' orders were no longer carried out, and they began to flee in spite of the harshness of military law.

......The horn sounded again, but this time it was no longer an order to attack, but a signal to retreat, and the enemy soldiers in front of the formation heard it and ran back quickly, and they were afraid that they could not return to the formation.

"Your Majesty, Commander Zhuang requests to send troops to pursue!" Guan Tongshou reported at this time.

"Forget it, poor Kou Mo chase! What does the cardinal think? At this moment, it was sunset, Zhao Yu looked at the enemy formation, and said in a deep voice.

"The minister also thinks that it is not appropriate to attack!" Zhang Shijie said, "The ministers are not chaotic when they watch the enemy's formation, and they advance and retreat in an orderly manner." In addition, our army is an infantry army, if it is attacked, the enemy and cavalry will be easily outflanked and surrounded from the flank, and the two armies will be in a melee, and our ballistae will no longer be effective, so it will inevitably suffer losses. ”

"The cardinal is worthy of being a veteran of the battlefield, I can see so many ways, I still need to learn more from the cardinal!" Zhao Yu arched his hand and said with a smile.

"How dare you!" Zhang Shijie said that he didn't dare, but his face was full of smiles.

"The cardinal is too humble, please give me advice at that time!" Zhao Hao smiled secretly in his heart, this is all said to be a thousand clothes and no sycophants, it seems that it still makes sense, and he has to pour another pot of ecstasy soup on him.

"Your Majesty has worked hard all day, please drive back to the palace to rest, and leave the rest of the trivial matters to the minister!" Of course, Zhang Shijie was full of joy and asked for his life.

"Then there's Commander Lao!" If you say that you are not tired, it is false, and it is not your own strength to deal with these military affairs, so you will go down the river......

The next day, Zhao Hao woke up early, but still felt sleepy, and he breathed a sigh of relief when he heard that there was no movement outside, he had been worried that the Mongols would launch a night attack last night, and it seemed that it did not happen, but he couldn't sleep again. Asked people to come in to wash and change clothes, but a cup of tea has not been drunk before yesterday's battle report has been delivered, yesterday's war Yuan army suffered a lot of damage, four thousand people were basically disabled, and hundreds of large and small army generals were damaged. The Song army suffered more than 400 casualties, most of the soldiers were wounded by stray arrows, and the losses were slight, but the ballistas were damaged due to continuous firing, so they continued to be replaced and maintained.

"Order, order the Chinese army to take over the defense of the east gate, and the rear army to enter the city to rest!" Zhao Yu thought that since it was a training unit, then they all took turns to practice, and it was not easy to find a good sparring partner like Instigation, so he made an order.

"Your Majesty, although the rear army has fought hard, it has not yet lost its vitality, and it can still fight again!" Zhuang Gongwang, the assistant director of the Military Aircraft Department on duty, did not immediately start writing, but asked.

"The credit can't all be made by the rear army, everyone must also be evenly distributed!" Zhao Hao said with a smile, he knew that Zhuang Gongwang hoped that his brother could have more experience and mature as soon as possible, but in fact, he had no intention of competing for merit.

"Your Majesty is laughing again, the minister is not selfish!" Zhuang Gongwang couldn't see that His Majesty was joking with him, but he couldn't do this as a courtier, and he was still right.

"Hehe, why bother. If we hit Quanzhou, it is equivalent to stabbing a hornet's nest, how can Kublai Khan let us go, he will definitely send troops to chase and fight, and there will be battles in the future. And most of the generals of our infantry army have not gone through a big battle, and they have to go into battle to hone themselves and accumulate experience for future operations. Zhao Hao said with a smile, "Therefore, I have no intention of despising my brother in this arrangement, and besides, the rear army has been stationed in Dongcheng since it landed on the shore, and it should also be properly rested and entered the city to have a look, otherwise it will not come back in vain!" ”

"Your Majesty's actions have deep meanings, and the ministers are stupid and fail to comprehend!" Zhuang Gongzhe listened to Shi Lidao.

"This matter will be presided over by the cardinal commander, remember to strictly prevent the Yuan army from sneaking up on the counterattack and break through our defense line in the change of defense!" Zhao Hao admonished again.

"The minister has written it down, and he will draft the decree immediately!" Zhuang Gongwang immediately picked up the pen and wrote it like flying, and Zhao Yu read it and approved it, and immediately sent it to Zhang Shijie.

After finishing the urgent business, Xiao Huangmen had already delivered breakfast, a bowl of porridge, two eggs, and two cooking cakes. Zhao Yu looked at the official document sent yesterday while eating, and when he saw the consumption and replenishment after entering the city, he couldn't eat. Needless to say, Quanzhou is rich, and the abundance of materials is beyond his imagination, if he wants to raise some copper and iron in Qiongzhou and find some rare things, he must not only mobilize the strength of the whole island, but even need the office to smuggle at a high price.

And every time he fights, Zhao Yu is very tight, and the money is spent like water, not to mention, it is to deal with the aftermath after the war, and the replenishment and consumption give him a headache, and some things can't be bought with money. The two yamen of the Duzuoyuan and the Imperial Prison are even more meticulous, and they all know that the materials in their hands are used less and less, but they don't know when they will be replenished, but they also have to ensure that the military supplies are used, and they can't leave some back, in case they need to use it when the time comes, but they can't get something.

In Quanzhou, it is a different scene, it is one thing to beat the local tyrants to have money, and it is quite convenient to replenish materials. At the beginning, Zhao Yu went to Qiongzhou to serve with only 20,000 or 30,000 soldiers, but he was worried that he would not even have enough to eat, so he had to 'rush to buy' a large amount of grain in Guangzhou, lest there be a food shortage. There were 50,000 or 60,000 soldiers in Quanzhou, twice as many as their number, but their arrival not only did not cause a shortage of grain, but even grain prices did not fluctuate. Before the siege of the city and the closure of the city for seven days, all materials could not enter and exit, and there were 200,000 people living in Quanzhou City who were still not in danger of lack of food, which showed the abundance of reserves.

Of course, the tens of thousands of troops are not as simple as just eating, the consumption of firewood, rice, oil, salt and other materials is amazing, but the army can do as it is needed, and there is no need to worry about running out today and not being able to buy it tomorrow. And in Qiongzhou, the most rare copper and iron, cowhide, sulfur, medicinal materials, and livestock are all at your fingertips, anyway, as long as you have money, you won't have to worry about not being able to buy what you want. Although there was a report from the Secretariat in advance, the abundance of market supply is beyond the imagination of Zhao Hao, a modern person.

"Alas, I don't even want to leave!" After reading it, Zhao Hao was not only very emotional, because he knew very well that fighting a war is a matter of burning money, war is a contest of comprehensive national strength based on economic strength, and economic mobilization is a bridge for transforming economic strength into national defense strength, and Qiongzhou is still too poor.

As the saying goes: when the cannon goes off, there are ten thousand taels of gold. With the development of society, the dependence of war on the economy has deepened, and the damage to the economy has gradually increased. In primitive society, a few sticks and a few stones can go to war. In the slave society, bronze weapons have begun to be used, and the cost of war has risen with the tide, so it is necessary to consider whether there is still food left at home. In feudal society, there is a saying that soldiers and horses go first before grain and grass are moved, and it is difficult for a family and a region to support large-scale wars. Not to mention modern society, if you don't have money, you can't even fight!

Therefore, as a ruler, while conducting wars to maintain political status and seek economic benefits, it is inevitable to pay a staggering economic cost. If we ignore the economic losses of the war or underestimate the economic risks of the war, we will make mistakes in strategic decision-making, and even exceed the tolerance of the national economy, and the national economy will experience serious turbulence or even a total collapse, and the consequences will be unpredictable. Carrying out research on the assessment of the economic damage caused by war, predicting and analyzing the damage that may be brought about by war, and estimating the maximum ability of the national economy to withstand war will become a task that strategic decision-makers have to face.

As far as Zhao knows, the United States has long established a war experience laboratory, and its primary task is to devote itself to the simulation research of transforming the national economic potential into war capabilities. Before the outbreak of the Iraq War, the RAND Corporation of the United States estimated that the cost of economic mobilization was as high as 3 trillion US dollars, and through computer simulation, it presented the real-life mobilization steps in the process of raising, storage, turnover and transportation of strategic resources, especially the cost of containers required to load and unload military supplies in the desert area, laying the foundation for the visual prediction of the actual combat mobilization cost of the US military. It can be said that a country's ability to mobilize economically will have a direct impact on the effectiveness of its operational or non-war military operations.

Economic mobilization simulation is to construct a model of the demand for combat support resources in wars of different scales, study the areas and resources that need to be mobilized, simulate the operation mode of the economic mobilization system at different levels, analyze the problems and deficiencies existing in the national economic mobilization system, and propose solutions and improvement measures. As wars and emergencies become more dependent on the economy, so does the role of economic mobilization. However, economic mobilization involves a large number of military and civilian units, and the coordination organization is complex, and the cost consumption is huge.

After the outbreak of the Kosovo War, the US-led NATO forces, while using military means to strike at the military targets of the Federal Republic of Yugoslavia, also bombed dozens of its cities, enterprises, and state-level facilities in turn, directly causing economic losses of more than $100 billion, making the economy of the Federal Republic of Yugoslavia beyond the scope of what it could bear, and achieving maximum benefits with the smallest losses. Coincidentally, a pre-war assessment of the funds needed to combat extremist groups concluded that air strikes were a relatively safe and economical option that would not put too much pressure on the budget and provide an important basis for deciding on air strikes against terrorist bases. Another year, before Russia went to war against Georgia, the budget committee of the Russian State Duma also calculated the required war expenses.

"I'm going to have to calculate it in the future!" Zhao Hao thought about it for a while, thinking that big families like bald eagles and polar bears had to be careful in a small battle, and they just gathered a grass platform team, so they didn't want to be big-bellied. Although he had thought of this layer before, it was only a rough calculation, and he felt that he would not lose money in a battle, and he still had to make money, and he did not study in depth how much it would cost to fight a modern war? Can the national economy afford it? It did not take into account the direct economic losses of the war, the indirect economic losses of the war, the losses of the labor costs of the war, and so on.

Under the reflection of 'dangchang, dangchang'......', Zhao Yu couldn't eat anymore, and gently tapped the plate with chopsticks to think about his thoughts.

"Stop, don't disturb the official family!" Seeing His Majesty constantly banging on the dishes, Xiao Huangmen, who was waiting on the side, wanted to come forward to ask, but was stopped by Wang De.

"The official family is ......" according to the country customs, after eating, it is disgusting that the food is not palatable, or not full, and only beggars will knock on the rice bowl along the street to ask for food, which is extremely rude, if it is not a joke for outsiders to see, Xiao Huangmen said softly with some puzzlement.

"I'm like asking for food, right?" Although the voice was small, Zhao Hao heard it and took over the words.

"Officials, they are not sensible, don't listen to them!" Don't say that the emperor wants to eat, or he can't say that he wants to eat, Wang De was startled and hurriedly explained with a smile, and then turned his face to a few waiting little yellow doors, "I don't have the eyesight to see, can't I see that the official family is thinking about things?" disturbed the officials, and talked nonsense, I can't see that I have picked your skin! ”

"The official family spares his life, and he knows how to spare his life!" When the little yellow men heard this, their faces turned pale with fright, and they knelt down and kowtowed repeatedly. If it was said that His Majesty would peel human skins in the past, they would definitely scoff at it, but since His Majesty personally broke Shi Si's bones, everyone believed it, and anyone who didn't believe it was in a hurry with him.

"Alright, alright, get up! You're right, I'm not just a beggar for food, or a beggar. Zhao Hao said with a wry smile...... (To be continued.) )
