In front of the city walls, on the huge open ground, rows of heavy trebuchets, like giants, stood there.

Zhao Pu roughly counted it, there were about more than a thousand!

Trebuchets are called ballistas, which are divided into elastic trebuchets, torsion trebuchets, manpower trebuchets, gravity trebuchets, return cannons, counterweight trebuchets, counterweight trebuchets, and so on.

And the most famous is the return cannon, using the principle of leverage, one end is equipped with a heavy object, and the other end is equipped with a stone projectile to be fired, before firing, one end of the ammunition must be placed with a winch, pulley or directly pulled down by manpower, and the other end with a heavy object also rises at this time, after putting the stone bullet let go or cut the rope, let one end of the heavy object fall, the stone bullet is also thrown out of the trend, some stone throwing machine can eject nearly 1000 pounds (about 454 kilograms) of the projectile body, the power is huge.

The trebuchet was an excellent siege weapon, and modern tests have shown that a boom 50 feet long and a 10-ton counterweight can throw 200 to 300 pounds of stone over a distance of about 300 yards. By the mid-14th century, some stone throwers were capable of projectiles weighing nearly 1,000 pounds.

There is also an important psychological effect, which can throw boulders into fortresses to smash houses, and can also scare the people of the city by throwing filth, dead beasts, enemy dead heads, and prisoner corpses.

"That's amazing! actually used so many heavy ballistas, it was too much to give Lao Tzu face! ”

Zhao Pu's face was still the same, and he didn't seem to care, but his heart trembled.

The Jin army actually used so many heavy ballistas, this is to fight a Yuan Dynasty version of the Xiangyang War!

In the original time and space, the Jin army went south many times, attacked the city many times, and also used ballistas, but mainly light. Most of them are based on surprise attacks. Only in the Yuan Dynasty, in the face of the strict defense system of the Southern Song Dynasty and the iron-clad Xiangyang, the Yuan Dynasty created the "siege king" of the cold weapon era, and returned the cannon!

The entire Xiangyang, under the fierce blow of the return artillery, finally fell.

Huihui cannon, made by "Huihui people", originated from the mathematically developed Arab Empire, and was carried forward in the Yuan Dynasty. When the Mongol army attacked Xiangyang, its reputation was extremely prominent!

And in this era, there were no return guns, but there were also heavy ballistas that were infinitely close to return guns.

In fact, some heavy ballistas were made. There are no technical difficulties at all, it just doesn't work.

First of all. Relatively bulky. The cost is relatively high, there is no waterway, there is no shipping, and it cannot be transported on a large scale; Secondly, it is necessary to have a relatively wide ground before the trebuchet can be placed. If the ground is rugged and uneven, it cannot be furnished at all; Thirdly, it is necessary to have strong cavalry. Take control of the field at any time and prevent the enemy from destroying it.

In some areas of the north where the waterways are inconvenient and transportation is inconvenient, it is simply impossible to transport a large number of heavy ballistas.

And when the Jin army attacked the north or some cities in the south of the Yangtze River, only small ballistas were needed, and there was no need to use such big guys. In the northwest, some of the rugged ear fortresses had narrow fronts that could not be equipped with heavy ballistas.

In short, except for Xiangyang, this strange city, will enjoy heavy ballista bombardment; Other cities are simply not possible and will not be treated like this.

Zhao Pu can imagine that the huge stones of the grinding disc fell from the sky, smashed houses, smashed soldiers, and the damage to morale was huge!

Historically, the Southern Song Dynasty army, which had always been good at defense, finally fell under this fierce attack. At this time, these soldiers under his command may be able to hold out in a short period of time when it comes to defending the city as well as the Southern Song Dynasty army in that time and space.

"Ladies and gentlemen, is there a way to deal with it?" Zhao Pu asked, at this time he already had a way to crack it in his heart, but he just asked on purpose.

Defending the city, after all, is not his business alone, but the whole army, work together, and use their brains together!

"Your Majesty, the boulder is dangerous, it's better to evacuate quickly!" At this time, Wang Boyan immediately said, opening his mouth is to run away.

Zhao Pu's face turned blue, and he had the urge to raise his hand to give Wang Boyan a mouthful!

"Your Majesty, the boulder is dangerous, please evacuate quickly!"

"If a gentleman doesn't stand under the dangerous wall, it's better to evacuate quickly!"

"Your Majesty, the Jin Army's ballista is about to be launched!"

…………

All I heard was evacuation, running away, and leaving, and none of them put forward an opinion on how to crack the heavy ballistae of the Jin Army.

Zhao Pu was angry, and his heart was also extremely sad, why Lao Tzu's subordinates were all this group of goods. At the critical moment, I didn't think about how to break the enemy, but I was thinking about how to evacuate and run away.

"Wang Shouyi, you have a way to crack it!" Zhao took a deep breath and kept saying to himself, don't be angry, don't be angry!

"This ............," Wang Shouyi said, "some of the soldiers are evacuated, and some of the soldiers are clinging to the city wall, so they can naturally be safe!" ”

It's a stupid solution, but it's also the most practical way!

"Wu'er, do you have a way to crack it?" Zhao Pu asked his woman again.

After thinking for a moment, Wang Wuyue said: "You can use trebuchets to attack, mainly chain bullets, to strike, and destroy the enemy's heavy ballistas!" ”

Zhao Pu nodded, this is a good idea. The Jin army can use trebuchets to attack, why can't the Song army use trebuchets to counterattack, at this moment, the number of trebuchets and the attack effect of Fancheng are not inferior to those of the Jin army. It's completely possible to ballista against ballista, against a bombardment. And chain bullets can cause fatal damage to the wooden frame of the trebuchet!

"What else?" Zhao Pu asked again.

"Your Majesty, evacuate quickly!" Wang Boyan didn't care about the etiquette of the monarch and the minister, stepped forward to pull Zhao Pu, and pulled him down to the city.

Zhao Pu smiled and said: "It's late, the Jin army has already launched, and the heavy ballistas are starting to wield!" Hurry up and hide by the wall! ”

As he spoke, his figure flashed, and he hid under the battlements, clinging to the city wall, and his eyes were blazing looking down.

As the ropes were cut, the ballistas were fired one by one, and the stone projectiles were fired one by one, the big ones were as big as the grinding plate, and the small ones were as small as the heads, and they were disturbed one after another, like meteorites, falling from the sky.

The other ministers were also panicked, leaning towards the city wall, trying to avoid it.

Zhao Pu looked at the stone bullets in the sky, both frightened and excited, and his eyes flashed with bloodthirsty light.

After the artillery bombardment, the crater formed is often the best place to avoid the artillery; And after the ballista is fired, clinging to the battlements, it is often the best place to avoid stone shells.

If you are unlucky, you hide under the battlements, clinging to it, and you are still smashed, or even killed. Who is to blame?

Who let luck go back like that!

One by one, the stone bullets fell, the city walls were trembling, and Zhao Pu's heart and liver were also fluttering.

The ballistas continued to wield power, wave after wave, like a tide, and only stopped after a long time!

"Ballista attack in the city!" At this time, Wang Shouyi stood up and gave an order, and the ballistas in the city were mighty, and chain bullets were shot out.

Chain bullets, in fact, are not complicated jobs. Most of them are two thicker ropes, connected to two stone projectiles, which are projectile under the action of a trebuchet. Chain bullets, mainly against the wooden frame of the trebuchet, as long as they are entangled by the chain bullets, under the huge inertia, under the impact, it is enough to destroy the tall wooden frame.

In one round of shooting, more than 200 chains of bullets were ejected!

It's just a record, it's really not good!

Because of the problem of perspective, the chain bullets thrown out, more than nine layers, all missed, and some either fell behind, or were too far forward, and did not hit the trebuchet, but hit some Jin Army soldiers.

But a few still hit it!

"Whoa!" With a soft sound, the wooden frame of a trebuchet fell apart, and suddenly smashed into five or six Jin sergeants under the wooden frame;

Listening to this sound, there were immediately bursts of cheers from the city wall!

It's just that good luck is limited!

Zhao Pu roughly counted it, and it was only five smashed!

That is to say, 200 chain bullets were ejected, and only 2.5 percent of the hits were made!

The record is so bad!

Zhao Pu had to admit that he operated the ballista and was responsible for firing! It is also a technical job, and without a well-taught level of visual inspection and rich experience, you can't play ballista at all. In the hands of novices, ballistas fire stone projectiles, whether they can hit people or not depends more on luck!

"Luck!"

Zhao Pu sneered, today is the first and last time for the Jin Army's heavy ballista!

Tomorrow, he is ready, and then the ballistas will suffer!

Hum! , Golden Vultures, waiting for grandpa! (To be continued......)
