The crossbow, according to legend, was invented by Zhuge Liang, and as early as the Three Kingdoms period, it had been equipped with the army, but because the problem of arrows could not be solved, there was no large-scale equipment. Pen % fun % Pavilion www.biquge.info

Among the equipment of the forbidden army, Zhao Xin scanned a repeater and modified it on his foundation.

In the information age of the 21st century, you can find most of the information on the Internet, ask GOGLE about foreign affairs, ask Baidu about internal affairs, so to speak, the two major search engines can solve most of the problems, not to mention when the eyeball economy arrives, people want to be better than others, what do they rely on.

Some Internet celebrities rely on their appearance, using exquisite makeup and head-scratching posture to attract some fans on the Internet, but there are still a group of people who rely more on their personal strength.

For example, more and more outdoor live broadcasts, skill live broadcasts, and even live broadcasts of scientific experiments, the Internet has shortened the sense of space and distance, creating this kind of economy and vanity, and of course, more and more people are showing their stunts.

There are experts on the Internet, they almost use their ingenuity, as well as their enthusiasm for cold weapons, all of them, according to legend, Zhuge crossbow can shoot 10 arrows at a time, and it has been lost in the 21st century.

However, in later generations, it can be used in a similar way to the crossbow box to ensure the rate of fire of the crossbow, this genius idea, will use springs and some other materials, which can be transformed on the basis of the repeater, as for the problem of the arrows that plague the repeater, as long as there is a card system, copying is not a problem.

Zhao Xin seems to have found the card system at this stage, the greatest significance for him, no matter how difficult it is to process, it consumes a huge amount of manpower, for him, it is just the embodiment process of the card system, a arrow that may take several days, or even half a month, can be finely crafted, in the card system, it restricts it, only the time for the card to appear.

For example, grain, any kind of food, it takes at least 2 months to be able to produce through planting, but in the card system, it is based on the unit, and the others are similar, as long as there is money and a card system, you can manifest a large number of them.

Then, as long as it takes a lot of time to make a crossbow arrow that meets the requirements, the biggest problem of the repeater does not exist, and the repeater has not been used on a large scale in the army, not that he is not powerful, but that the arrow is difficult to make.

The arrows of the traditional Northern Song Dynasty repeater are really expensive, 20 arrows are almost worth the price of a repeater, I believe that after adjustment and modification, it will be more expensive, but in terms of time, it is very short, similar to ordinary arrows, which can become a conventional weapon.

Automatic weapons can reduce manpower, in front of the squad platoon, the formation of the previous battalion, even regimental firepower, even the crossbow can not compare with automatic firearms, but it is also the era of cold weapons, the fastest weapon, a skilled crossbowman, between 10 breaths, can shoot 10 arrows, and the arrow box can be replaced, as long as prepared in advance, the crossbow does not have high requirements for strength, in principle, a person can last for half an hour, or even an hour of shooting.

What is this concept, an hour and 3600 seconds, an average of 7200 arrows an hour, 2 hours, that is, 14400, this is a person, even if the accuracy is only one-tenth, one-fifth, this arrow, heap also piles people to death.

The number, at some point, when it reaches a certain level, will make people stunned, the improvement of the longbow is only a little, an average of four or five seconds of an arrow, which is already a terrible speed, now, two in a second, maybe the lethality is closer, but for the defense of the pillbox, it is simply incomprehensible.

When the time comes, even if 20 people are stationed in a bunker, these people don't even need to train, they hide in the shooting holes of the bunker to shoot, they don't need to be too powerful, as long as there is an accuracy, 20 repeating crossbows, under the premise of the guarantee of crossbow arrows, will become a nightmare.

This repeater, there is no way to take it out for the time being, but Zhao Xin will slowly modify it, after all, the crossbow is also a crossbow, even the more dangerous kind of crossbow, even Wang Song's personal crossbow is not a crossbow, even in the Northern Song Dynasty, it is also tightly controlled, large-scale installation, there will definitely be problems.

Even if Zhao Xin didn't propose a repeater, the unique design of the bunker made Sun Ji and Xue Yu stunned.

In fact, in the era of cold weapons, for the understanding of tactics, two or three fortified cities, not far from each other, can be each other's horns and support each other, but no one is as mad as Zhao Xin.

A pillbox, 40 meters high, all are straight up and down, can not climb, can only pass through the ladder, but in each layer of the bunker, more than 5 meters, there are a variety of shooting ports, can not let people pass, but can shoot arrows, can be attacked with long weapons, this is an iron hedgehog general.

At the very least, Sun Ji and Xue Yu can't think of how to capture it, push it, and have seen the strength of the cement pier, even if it is half a meter thick, it is already higher than the original city wall defense, it is a stone, you use a catapult to smash it with a stone dozens of meters away, or even a hundred meters away, how many stones do you need to be able to smash the same stone.

Not to mention, in the height, there is a place where you can shoot arrows, 40 meters high, condescending, as long as you are careful, you can attack indiscriminately, so that the defense line is almost impossible to break, and there are tunnels and support behind it, 12 arrow towers and the main house support each other, almost expanding the original defense several times.

The space between them is specially designed, and if you don't know a little, when you enter this space, you will be set on fire by three, or even four or five arrow towers, no matter how strong the soldiers, in the face of this natural difference, they can only hate on the spot.

There are 12 arrow towers, 6 of which are near the mansion, they are quite close to the mansion, and they are the most important internal defense of the mansion, enough to protect the entire mansion in it, and the others are scattered around to further increase the strength of the defense.

Even if it is the outermost pillbox, because of the superposition of attack power, it will be reduced by half, or even seventy percent of the attack area, this is for generals who have suffered losses or have experience, even if it is Sun Ji, under Zhao Xin's introduction, he has a considerable understanding of the entire defense system, but if he really puts him in the position of the attacker, he can't help but feel numb in his scalp.

The defensive strength of the whole design will be extended to a strong level, which is unimaginable, as long as there are enough defenders in it, not much, just these people in the militia are enough, there are enough logistics support materials such as food and grass, weapons, water, etc., even if he carries an army of 100,000, in a short time, he still can't do anything with him, this is no longer a traditional siege, iron-blooded generals fill the problem with human lives.

The unique design of the defense, at least, maybe 300 people can protect everything thoroughly, and even siege the city in a short period of time, can not play a role in consumption, the other side is at ease, as long as there is no problem with logistics materials, the possibility of direct attack is completely zero.

A simple design drawing, which did not look good at painting and seemed a little immature, was passed around in the hands of many generals, and finally returned to Zhao Xin's hands, and everyone's faces were all pale, and as soldiers, it was natural to position themselves as the attackers.

Such a mansion armed to the teeth, as if it is a hedgehog, it is difficult to start, but the hedgehog, for the hungry beast, as long as you endure the wound, it is not impossible to eat, but this, every thorn is hard, enough to kill, you can't consume it, you may ignore the sacrifice of the attack, the death of countless lives, in exchange, is only a small gain, if you are not careful, you will be touched by this defense to break the blood.

Sun Ji and Xue Yu, until they left Zhao Xin, when they returned to the room at night, they didn't reply, what kind of person would design such a madman, there are dark traps in every place, and the killing is played to the extreme defense.

But I have to deny that cement is the core of it, replaced with the previous glutinous rice milk or yellow mud paddle, not to mention whether it can be built so high, encourage the bunker outside, if the attacker is ruthless, with a little sacrifice, you can use giant logs and rushing cars, crash it, not only get the tunnel straight into the mansion, but also gain the advantage of psychology and morale.

However, once these blockhouses cannot be destroyed by existing siege methods, even the smallest pillboxes are like a point, which is fixed to a dead place, which is of great tactical and strategic benefit.

A design drawing, shocked Sun Ji and others, they have no reason to object, but in the implementation, Zhao Xin encountered a problem, the entire amount of work is too large, the courtyard wall of the mansion, will be expanded to 5 meters, the height will reach 20 meters, plus some internal design, the total height will exceed 35 meters.

Compared with the ordinary city wall, the workload will be several times more, although once this project is completed, this mansion may be the house with the highest defense strength in the entire Northern Song Dynasty, but the amount of this project will be several times.

The defense is piled up with all kinds of fortifications, and these fortifications are all very thick walls, for example, such a project, bulldozed and placed on top of ordinary mansions, can be dozens, or even hundreds of mansions of the same size.

Ordinary mansion, the wall is at most double bricks, here is simply five meters, the periphery of the whole house, 5 meters thick, 32 meters high courtyard wall, the total length is not long, only about 280 meters, but he is unbreakable, 5 meters thick wall, any other method of breaking through the city wall, here, can not play any role at a certain point,

However, the construction of the 5-meter-thick city wall, compared with the double brick wall, the workload is dozens of times, plus the higher height and a variety of unique designs, the final amount of work will be terrifying.

Before Zhao Xin, he had asked Miao Yuan to pay attention to the matter of craftsmen, and even Wang Song was sent out, it can be said unceremoniously that there are not enough craftsmen, if you want to complete this project in a short time, it is almost impossible, conservatively estimated, at least 250 craftsmen and 1500 laborers, under the premise of needing secrecy, this is also a difficult task.
