In the eyes of many people, he is a representative of China's backwardness, and he can't even produce steel, let alone qualified cannon steel, the reason why the War of Resistance Against Japanese Aggression has been fought for 8 years, Japan is stronger than China is all-round, and China is too weak is also a fundamental reason.

Including bullets, shells, artillery, guns, almost no self-produced things, most of which rely on imports, how to defeat Japan, the Kuomintang is so hard, not to mention even worse Kuomintang guerrillas.

It was also a helpless move to take out the tree cannon to make up for the lack of firepower.

In the era of thermal weapons, it was somewhat backward, but at that time, for the Second World War, even if it was in the War of Resistance against Japan, it could not confront the artillery made of steel head-on, but compared with ordinary artillery, especially in the mountain and forest warfare, it was only a little less durable, using qualified wood, if the iron hoop of fine iron was added to the outside, used to improve strength and toughness, his performance would not be worse than the primary artillery of the 189th century.

This unique is arranged, on the basis of the tree cannon, made a certain improvement, the Song Dynasty, is the most developed period of China's economy and science and technology, many inventions that have a profound impact on later generations, are in this era, and carry forward, from the technical level, this era is not weak.

Foot armor, divine arm crossbows, and even some gunpowder weapons, this is the advanced place of the Northern Song Dynasty, and even at a certain level, except for a small number of things, most of the things are not bad compared to the Ming Dynasty.

The all-in-one machine gave Zhao Xin the opportunity to turn stones into gold, whether it was the bow body material of the moon bow, or the bowstring material, these are just precious treasures given by heaven through meteorites, and Zhao Xin can light up with the help of this body, even if it is a little expensive, but the performance of the alloy is very high.

It is a difficult task to make an iron cannon composed of pure this material, the cost is too high, it is ten, twenty, or even hundreds of times more expensive than ordinary steel, and when the iron cannon with them as the core, it will cost even more than a fortress.

No matter how rich Zhao Xin is now, it is impossible to have money to this extent, but using iron hoops to enhance the overall toughness and strength is the practice of new cannons in later generations.

The biggest weakness of the tree cannon is that its own strength is limited, under the impetus of gunpowder, it is very likely that it will be exploded, but a layer of iron hoop will convert part of the force to the iron hoop, and use the strength of the iron hoop to offset the fragility of the trunk itself, coupled with reasonable calculations and the toughness of the trunk itself, the power of this tree cannon is still okay.

According to conservative estimates, the artillery loaded with a single bullet is probably not less than the red-coated cannon of the sixteenth and seventeenth centuries and the Ming Dynasty in terms of its own power, but in terms of service life, it is far inferior to the cannon body made of copper or iron.

Metal materials, that is, metal materials, his wear-resistant, pressure-resistant and high-temperature resistance are much higher than those of trees, but if you simply shoot a few shots, the power of the tree cannon is not low at all.

Zhao Xin chose the tree cannon, for his power, as for durability, the production of the entire tree cannon, purely a technical work, around the decades, hundreds of years of trees do not know how many, after cutting, it is a carpentry work, cut into two halves to dig holes, and then after the carving is successful, it is hoopped with an iron hoop, and at most a layer of fire-resistant and high-temperature resistant materials is applied on the inner layer.

Even the lifespan, there is endurance training to figure out, in the case of maximum loading, the ultimate life of the tree cannon is 30 rounds, the first 10 rounds will not have an impact, the refractory material will withstand the high temperature of gunpowder burning, to the back, with the burning and continuous impact, the material of the tree body will gradually collapse, and finally to 30 rounds of explosion.

This safe environment is enough for the tree cannon, at least the first 10 rounds are acceptable, and it is a big deal to make more and use them as disposable supplies.

The biggest deficiency of the fortress is that in the face of the lack of artillery after the era of European science and technology, in the face of the huge siege artillery, the hard body of the fortress itself, will be a huge threat, people do not play siege warfare with you, directly destroy the city wall, when the city wall has a gap, and even the fortress itself has collapsed, how can you do it.

The fortress is with the help of the tall city wall and the design to the extreme personnel advantage, once the tall city wall can not play the role of a barrier, everything else is not to talk about, the scarcity of personnel is the advantage of the fortress, but once there is no city defense, this becomes an absolute disadvantage, after the artillery can easily collapse the fortress, this from the end of the Middle Ages, appeared in Europe of the strong fortress, quickly declined, leaving the stage of war, the war was easier to build, but also more suitable for the era of thermal weapons trenches and trench system replaced.

This is tantamount to cheating, the strong fortress itself, and the epoch-making weapon of the tree cannon, the other party has no hot weapons to attack the city wall, which represents a hedgehog-like fortress, and there are more terrible offensive weapons, the effect is not as simple as one plus one equals two, it is a big jade, far greater than two.

The appearance of Zhao Xin, a traverser, was originally a bug, and the card system popularized rare things, and used perfect gunpowder that had been purified and re-equipped, and the perfect combination of the three formed the huge power of the artillery.

When the 20-kilogram projectile of the artillery, driven by the explosion and combustion of 30-kilogram gunpowder, wreaks havoc on the crowd at the speed of sound, or even beyond the initial velocity of the speed of sound, the result can be imagined.

A cannonball, directly in the middle of the crowd, ploughed a blood-colored passage, and everywhere it passed, whether it was foot armor or something else, the strength of flesh and the protection of steel, under the impact of thermal weapons, like paper paste, corpses scattered across the field.

The rout soldiers were a little unstable all the way to Miaojiazhuang, but fortunately, Wei Gui's timely bullet pressure, his prestige showed its effect here, and these rout soldiers calmed down and slowly retracted.

The previous shotgun only fired 80 rounds, and there were still 40 rounds left, and in the back, the earth-shattering tree cannon only fired one shot, although the entire army was scattered, the natural disadvantage of the fortress was not able to pursue, and even after that, even the longbowmen did not take advantage of the chaos to attack, which also made the rebels suffer little loss.

But about an hour later, where the loss was reported to Wei Gui and Wang Xiansong, they still couldn't help but jump their eyelids, because the loss was too great.

There were almost 900 people who died directly at the head of the city, or were wounded, and did not come back, who were directly hit by scattered bullets, or fell from the wall, among them, only thirty or forty people suffered losses during the previous climbing and attack and defense, and the vast majority of them were caused by the tree artillery behind.

Because the battlefield was scattered, and even pushed each other, there were as many as 50 people lost in the stampede, but it was not shown in this report, Wei Gui knew about these, and he didn't have much to do, he was more concerned about what this weapon was.

The branches that look ordinary are thought to be just indiscriminate, and in the face of the things that are surrounded on all sides, there is no way to take them out, but they show such a terrible attack power, this is a step armor, even if it is a tragic siege in the northwest, there are no such big casualties when using the foot armor, but it fell on his head.

I have to say that the family provided by the Wang family is really outstanding, in this wave of attack and defense, the loss of personnel is the least, only more than 100, the most important thing is that they also took advantage of the chaos to get this weapon back.

More than 20 somewhat deformed steel balls, as well as the largest, directly in the final stage, wreaked havoc on almost 20 people Giant iron bullets, these were all placed in front of Wei Gui.

To understand it simply, for the back, the earth-shattering weapon, Wei Gui no longer pays attention to it.

That's right, that weapon is terrifying, especially for this dense crowd, whether it is a big shield, or a covered car, or even a shield made of stainless steel, it can't block the attack of such a weapon, after penetrating a dozen people, it still has enough lethality, and it will smash four or five, either dead or disabled, and it is not something that human power can stop.

But it also has his fatal weakness, he can only hit the distance, not the close, when attacking, the movement is too big, not only bright fire, but also loud sound, as long as a little attention, it is not easy to be attacked.

The most important thing is that it can only work in a dense crowd, as long as the camps are separated and not so dense, the lethality of a single shot is not very high.

The key is the former, according to the eyewitness description, the iron egg should have flown out of the trunk, but unlike the single bullet, this one is more scattered, there are at least ten or twenty of them in one shot, and the penetration effect is also very terrifying, at least five or six people can penetrate.

This is the most terrible, but also the most harvested, more than 900 people, almost all of them died under such scattered bullets, which is also the biggest threat to them.

However, eyewitnesses also provided an opinion that the object did not seem to have a fast rate of fire, as they did not look at the reloading process, and should have fired a different one.

The speaker was unintentional, the listener was intentional, Wei Gui's eyes lit up, and he understood in an instant, this thing was similar to a bed crossbow, even more troublesome than a bed crossbow, gunpowder weapons were also available in the Northern Song Dynasty army, and the reason why they were not popularized was that it was too troublesome and not very lethal.

Obviously, Miao Jiazhuang invented a new type of weapon, which has a certain lethal effect, and the damage to the step armor is not small, but it cannot hide the inherent weakness, that is, the slow rate of fire.

At this point, Wei Gui regretted a little, he had already lost so much, and the fortress should have been at the most critical juncture at that time, otherwise he would not have taken out the secret weapon, if he worked harder at that time, maybe he would have taken it down, instead of being in a dilemma like now.

After retreating, the other party must have completed the loading, that is to say, if they attack again, they need to risk paying a thousand or even more casualties before they can approach the fortress and even climb up, this is a huge problem, who will go on the premise of knowing that they will die?
