It stands tall and ferocious, coupled with the height of the sidecar, the two together make it difficult for a flying horse to overcome.

Other technical details of sidecars are that the handlebars of each car are one hand higher than the car body. This design allows the handlebars of the rear car to rest on the front car like a chain when forming a car formation.

Same as each other.

At the end of each sidecar, there is an iron rope loop to facilitate the connection to the car array.

Compared with ordinary vehicles, sidecars have four more movable legs at the four corners, just like bicycle stands. This is for practical considerations. In actual combat, the battlefield may be rugged, which makes some vehicles move on one side.

The high side and the low slope are very serious. There are still people on the car array, and the car is tilted as if it is a steep slope. How can it be operated? This is the role of adding wooden legs to the side car.

The wooden legs can not only balance the car body, but also fix it. A car with two wheels is easy to be bumped, but with four legs on the ground, it is as stable as an old dog.

In the car formation, the connection between the cars is the weakest. It is best to use iron chains. Iron is too expensive, so you can only use hemp rope. Hemp rope is easy to cut. In the car formation that surrounds the car, you only need to disconnect one link.

It will become easy to loosen immediately. This further highlights the role of the wooden legs. The wooden legs are stretched to the ground. Even if the side car is separated from the front and rear, a single side car can be carried as stiffly as a small fortress.

In order to further strengthen the sturdiness of the sidecar, rivet stakes were also used. There were small holes on the front and rear panels of the sidecar. During battle, a long gun was used as a rivet stake through the hole and nailed to the ground.

, the car is firmly fixed and cannot be knocked away.

A side van is just an ordinary vehicle with a panel added to one side and some slight modifications. Its cost is slightly higher than that of an ordinary vehicle, but not much higher. The carrying capacity of a side van is not much different from that of an ordinary vehicle. Therefore,

The way to equip sidecars is to bring as many sidecars as there are ordinary grain trucks. In other words, there are as many sidecars as there are grain trucks.

The Semen Cart is a city defense or offensive machine. The reason why it is said to be a city defense or offensive instrument is because this instrument can be used to defend the city as well as to attack.

For example, when attacking a bridge or attacking the enemy's formation, you push the sword cart upwards. If you have some terrain advantage and charge from a high position, the sword cart will directly break through the enemy's formation.

There was a sword cart placed in the city gate. Li Mengxi introduced the sword cart's unparalleled defensive capabilities to everyone. He said that the sword cart was made of hard wood and could not be hurt by swords, spears or stabs.

Zhang Fei looked around the knife cart with a suspicious look on his face. Hearing Li Mengxi's boast, Zhang Fei wanted to test whether the knife cart was so strong.

Zhang Fei chased everyone away, came to the sword cart, raised his foot and kicked the sword cart hard.

There was a kacha sound, and Zhang Fei kicked the knife cart to pieces.

Li Mengxi marveled at Zhang Fei's strength. He walked up and looked at the knife cart that had been kicked out of a hole, with a look of disbelief on his face.

Zhang Fei proved with his strength that the knife cart is not indestructible.

The blade on the knife cart was not installed, otherwise Zhang Fei would not be able to exert force so easily.

But Li Mengxi also realized that the sword cart's defense was lacking.

Li Mengxi then made improvements to the knife cart. He asked the craftsmen to cast a thick iron plate. The iron plate was two inches thick and was estimated to be 60 millimeters thick.

With such a thickness, bullets probably wouldn't be able to penetrate it.

After installing the iron plate, he also installed the blade. Li Mengxi invited Zhang Fei to try to kick him again. Zhang Fei was not stupid, but only a fool could kick the iron plate. Even one kick would make him useless.

In order to verify the defensive power of the knife cart with steel plates, Zhang Fei took a heavy ax and slashed at the knife cart. After a chop, the iron plate was not damaged but was shattered.

Iron plates cast from pig iron are easy to cast but are too brittle.

It seems that cast iron plates are not defensive enough, so forged steel plates are needed.

No need to test anymore, the tool cart is equipped with a two-inch thick forged steel plate, which is an iron wall that is absolutely indestructible.

When the sword cart is used to defend the city, its method of use is to block the city gate hole and hold the enemy in the hole in a non-contact manner.

Because it is a non-contact method, there is no hand-to-hand contact between each other with swords and chariots, and there is no hand-to-hand contact. The advantage for the defenders is that the city defender can slow down the rate of casualties. Moreover, because there is no hand-to-hand contact, there is no need for elite soldiers to push

The knife cart has the same effect as the ordinary civilians pushing the knife cart. This saves a lot of elite manpower so that the elite soldiers can devote themselves to more intense fighting on the city head. This is equivalent to increasing the number of elites in disguise.

When using a knife cart, the key is wrestling. Therefore, after a knife cart has basic defensive capabilities, whether the knife cart is easy to use depends on whether its wrestling ability is strong or not.

Li Mengxi strengthened three areas of wrestling for the knife cart. The first one is the wheel. The smaller the wheel, the slower it rolls, so our army has more reaction time. The second one is the axle. Li Mengxi replaced the ordinary axle with

Ratchet, the ratchet wheel can rotate forward, but it will get stuck when it rotates reversely. When used on a tool car, if I push the wheel outward, it can roll, which is rolling friction. If the enemy pushes in, the wheel will get stuck, which is sliding friction. That is, our side

It is easy to push the enemy troops out, but it is difficult for the enemy troops to squeeze in with a knife cart.

The third improvement in wrestling is the handle. The size of the knife cart is limited. The people who can push the cart behind are only the few people close to the knife cart. In order to let as many people as possible work together, add a handle behind the knife cart.

There are some long handles of uneven lengths.

With the addition of these long handles, the number of people who can exert force suddenly changes from a few to a dozen. On the other side, there are only a few people who squeeze in front of the knife cart to exert force, but there are more than a dozen people on our side, with more against less, wrestling

In Zhongnai, we will definitely win.

Julu City has a four-way gate. Four sword carts have been built and are always parked at the city gate. Once a war breaks out, the four sword carts can block the enemies coming from the city gate.

Among all kinds of armaments, the most complex is the sniper crossbow.

The difficulty in sniping a crossbow is not the crossbow itself, but the crossbow frame.

The principle of the sniper crossbow is very simple. It is like this. If a crossbowman stands and shoots, the accuracy will definitely be low. If he squats and shoots, the accuracy will be higher. If he puts the crossbow on the battlement, it will be supported by the battlement.

The crossbow didn't wobble at all and was as steady as a dog, so it would definitely shoot steadily.

One of the principles of the sniper crossbow is this: it does not wobble, it is extremely stable, and it is so stable that it is beyond the reach of human power.

Second, if you want to shoot accurately with a crossbow, you have to rely on experience. So, is there a shooting method that can pierce a tree with a hundred steps without experience? The answer is yes.

If you have no experience in handling a crossbow, your hit rate will inevitably be worrying. At this time, if there is a way to gradually fine-tune the angle and direction of the crossbow, then even if you don't have any experience in shooting crossbows, as long as you can adjust it little by little, you will eventually be able to shoot a crossbow.

It can achieve the ultimate accuracy of crossbow shooting.

Li Mengxi's idea for making a sniper crossbow is to install the crossbow on a super stable frame, and the frame must be able to be fine-tuned bit by bit.

It is not difficult to fix the crossbow, but it is extremely difficult to fine-tune it and stabilize it after fine-tuning it.

The craftsmen have always failed in the sniper crossbow project. The craftsmen thought of various ways to make the crossbow frame, but none of them were suitable. Until not long ago, the gear appeared, and a new direction suddenly became available.

When shooting, there is one horizontal direction and one vertical direction. Therefore, as long as there are two gears, one can adjust up and down little by little, and the other can adjust left and right little by little, the sniper crossbow is complete.

According to the known gear knowledge, a group of gears have different sizes, and the rotation angles are also different when rotating at the same time. From this point, the gear sensitivity is adjustable, and you can have as much precision as you want.

During the sniper crossbow test, a target was shot between the battlements on the city wall, and then at a distance of a hundred paces, a sniper crossbow singled out thirty crossbowmen.

At the beginning, the crossbowmen had high accuracy, and the arrows they fired basically did not miss far, while the sniper crossbow could miss thirty or twenty steps at the beginning.

But as the sniper crossbow frame was fine-tuned little by little, the accuracy increased steadily.

In the end, after the crossbow's shooting height and shooting direction were stabilized, every arrow fired went towards the target, and its accuracy completely exceeded that of ordinary soldiers.

At the end of the test, the thirty soldiers missed more than 500 arrows in total. The number of arrows that hit the battlements was 12. The total number of sniper crossbow hits was 21, excluding those that were shot when adjusting the accuracy at the beginning.

After the accuracy of the arrows is adjusted, on average one out of a dozen arrows will hit the target.

A hundred steps, shooting from low to high, is more difficult than piercing a poplar in a hundred steps. Although the sniper crossbow cannot pierce a poplar in a hundred steps, an average of a dozen arrows can pierce a poplar in a hundred steps, which is far beyond the reach of ordinary soldiers.

Sniper crossbows can also be mass-produced. The brackets of sniper crossbows are cumbersome and difficult to operate. They are of little use in field battles. They are also of little use when defending a city, because from the angle of the defender, the enemy troops below the city are moving around in a mess.

, if you use a sniper crossbow to defend the city, you will waste a lot of effort and just aim at a position, but the enemy is no longer there.

The defender's output is more important than accuracy, and strain is more important than accuracy.

The only time the sniper crossbow can be effective is during a siege.

The accuracy of sniper crossbows has approached the shooting limit of crossbows. Sniper crossbows are used when attacking a city. After adjusting the angle, only three or two sniper crossbows need to be pointed at a city battlement to directly lock the battlements.

When the enemy is locked at a battlement, he has to either avoid it or carry it hard. If he carries it hard, the crossbow arrows will swish one after another as if they have eyes. No matter how many people there are, they will not be enough to kill him. No matter how good he is,

The armor was able to block a few more blows, even with a shield, but the space on the city was limited, and the troops on the city head were also limited. It would take one person to block the battlements with a shield, but there would be one less person on the other side.

Moreover, if the battlements are blocked, the defenders themselves will not be able to shoot arrows from the battlements, nor will they be able to throw stones and pour gold juice from here.

Locking up a battlement on the defender's side is equivalent to destroying a remote output point on the defender's side.

When there are enough sniper crossbows and all the enemy's battlements are locked, then most of the enemy's long-range troops will be eliminated, and most of the city defense will be eliminated.

As the saying goes, conquering the enemy without fighting, the sniper crossbow is a powerful suppressive weapon that can reduce a large number of casualties when attacking a city.

When Li Mengxi and a group of people were testing the sniper crossbow, Lu Zhi turned around. Li Mengxi had a weapon in hand and invited Lu Zhi to test his shooting skills. He was young and energetic and wanted to test whether Lu Zhi, a great scholar, was the legendary scholar.

Liu Bei was well aware of the power of the sniper crossbow and refused to allow him to compete. Lu Zhi agreed with a smile.

Lu Zhi chose a hard bow. The bow was as thick as an egg. Anyone who could shoot a hard bow would shoot arrows faster and more accurately. It can be seen from this that Lu Zhi must have good shooting skills.

After shooting at the eighty-step target, Li Mengxi set up a high platform and set up a sniper crossbow on the high platform. After adjusting the crossbow, he began to compete with Lu Zhi.

The result of this competition destined Lu Zhi to fail.

Lu Zhi may not be able to approach the accuracy limit of the bow, but the sniper crossbow's crossbow frame that can finely adjust the angle and direction completely approaches the accuracy limit of the powerful crossbow.

In addition, the bow Lu Zhi chose at random felt unfamiliar to the hand, and Li Mengxi stood at a high place and shot the arrow from above with a straighter path. This made Lu Zhi ultimately defeated.

At the eighty-step target, Li Mengxi shot fifty and missed an astonishing forty-five, while Lu Zhi shot fifty and only missed thirty.

He lost to Li Mengxi and was completely defeated. Lu Zhi repeatedly lamented that his future life was terrible.

Liu Bei came over and said with a smile, "Teacher, please don't be deceived by Xi'er, he is just using his weapon to deceive others."

Later, Liu Bei and Lu Zhi explained the subtleties of the sniper crossbow. After Lu Zhi listened, he tried it himself. From a distance of eighty steps, every arrow missed and all missed.

A few small gears and a small crossbow stand actually increased the accuracy of the crossbow by more than ten times. Lu Zhi was amazed.

Lu Zhi was surprised that he lost to Li Mengxi in his proud archery skills. When Lu Zhi learned that this was due to his engineering skills, Lu Zhi was even more surprised.
