After drinking tea for a while, Du Zhongxiao asked, "What new machine are you busy with?"

Guo Zi said: "A few days ago, I asked the Iron Supervisor to find a way to build a machine for mass-producing musket bullets. Let's discuss that muskets are too expensive. Lead can be used for minting coins. Although it is much cheaper than copper, it is ultimately a valuable thing. So when I think of using iron instead of lead, why not make iron bullets directly? These days, I have designed a set of machines that can cut the steel bars by quantity, then press the pier into a circle, and then grind them for a few steps to become steel balls. Although the ones I have made are a little rougher, they are more refined than lead balls."

Du Zhongxiao opened his eyes and listened to Guo Zi's speech, he asked in disbelief: "Can you make iron bullets in batches?"

Guo Zi nodded: "Yes, not only can I make iron bullets, but also the price is extremely cheap. Now that the military fires fired fire bullets, there is no need to pick up the bullets fired. They cannot be remade, and it is not worth much. By the way, according to the new method of making, shells can also be made in the future, but they are not cold piers, but they are still cast into blanks, but they can be ground, which is much more accurate."

Du Zhongxiao nodded repeatedly, but unexpectedly Guo Zi did this. In the past, the military used lead bullets to use muskets in the army, which was too expensive, and he was as rich as a camp and field affairs, and he didn't dare to use them. He did not fire a few shots after several months of training for soldiers. He changed it to iron bullets, which could be manufactured on a large scale with machines, and the cost was not known how much it was reduced. The military could use them for training, and it was not even meaningful to pick up waste bullets.

In fact, Du Zhongxiao can also design a machine for mass-making bullets, which is nothing more than quantitative cutting and die forging, and then grinding, which can achieve mechanical manufacturing. However, it is too energy-consuming and Du Zhongxiao is plagued by affairs and has no longer the focus on it.

The cost of using guns and cannons has decreased, and everything is different from before. During large-scale combat, the number of bullets brought by musketeers increases, and they can fire more shots when attacking and defending. Not to mention that when you have something to do, it is much more convenient than in the era of cold weapons.

Speaking of muskets, Du Zhongxiao said: "How are you doing this now when you were asked to make muskets with rifled in the barrel last year? I have also seen rifled guns, but the accuracy of shooting is still not satisfactory. If you are far away, you will not have a clear head."

Guo Zi said: "We have put a lot of thought into this matter. The rifle in the barrel has been changed countless times. Now it is basically determined. However, when it comes to shooting accuracy, it is not only related to the barrel, but also to the bullet. One is the shape of the bullet, and the other is when loading and launching the gun, the barrel and the bullet must be closed. We have thought of many methods and tried them one by one. In addition to adding rifle in the barrel, the bullet also needs to change the shape. Like an arrow, there is a pointed head in the front and a thick back, just like an arrow used for a crossbow. The current method is to use a steel head in the front and a lead support at the back, which is tightly embedded together. When launching the gun, the lead support and the rifle are in harmony, so that there is no air leakage, and it goes out like an arrow, so that the correct head will not be tilted."

Du Zhongxiao was stunned for a while before saying, "If the bullet hits a person's body, won't the lead holder be deformed? After the deformation, it will be more difficult to remove it from the human body. It will cause greater harm to people than the previous lead pills."

Guo Zi thought about it and shook his head: "We haven't tried this, but the recommendation makes sense. A few days ago, jackals and wild boars were harming people. They used this gun to hit it, but the lead holder would be deformed."

Do you still need to ask this? The steel head in the front is hard, and the lead holder behind is soft. After hitting, it will inevitably deform and the wound will increase. Moreover, the wound is irregular in shape, and the person who is shot will suffer much more damage.

The rifled rifle is a sniper rifle, which is not a great technology. As long as Du Zhongxiao knows the concept of rifle, he will ask his subordinates to make it. With the current technology, after rifling, the coordination between the bullet and the barrel is higher and the loading is inconvenient. For musketeers, the most important thing is the firing speed, which can fire a few guns before contacting the enemy. One or two more guns can gain a huge advantage. Therefore, only snipers who fire precisely, but musketeers still use smoothbore rifles.

Guo Zi is smart and has a natural enthusiasm for invention and creation. He also has specialties in this regard. Unlike Du Zhongxiao, Guo Zi is focused on weapons and is determined to make several strategic weapons to break the cavalry advantages of the northern nomadic peoples. In addition to rifled rifles and bullets, as well as large-scale iron bullets, he has also spent a lot of effort on cannons in the past few months, explaining them to Du Zhongxiao one by one.

The key to knowing the range and power is that the bullet and the barrel must be closed. The less gunpowder gas leaks, the better, so I put in effort. The newly made shells also have wooden brackets behind them, and are closed with wooden brackets and barrels. The principle is the same as the bullets with lead brackets, but the cannon has shallow damage. Unlike muskets, the shells require rolling after they hit the ground, so they are still round.

Speaking of this, Guo Zi said: "The officials thought that it is not bad to add a lead holder or copper holder behind the shell, but the price is higher. Ordinary solid bullets are fine, like flowering bullets, because they will explode after going out, the better the more accurate they are. At this time, if the barrel has rifle, use lead holder and rifle to match it, calculate the time of blooming, and directly hit the enemy's head. It can be like a bullet without a round shape, but instead of a round shape."

Du Zhongxiao said: "If you can do this, you must have a trustworthy fuse. Otherwise, it will be useless if it is fried too early and late."

Guo Zi said: "A new young man named Zhang Qian has entered our Iron Prison. He was from Raozhou. When he saw Tiju asking him to use iron to smelite copper from the gallbladder, he felt it was very novel and he specially sent it to the Iron Prison. This man was very smart and studied and passed on his family. The school was very outstanding and assigned to Shiqilang's subordinates. Zhang Qian was very interested in the refining of various drugs into new drugs, which was the chemistry of Tiju's name-"

Du Zhongxiao said: "To transform one thing into one thing, this is what the alchemist often does. The Taoist priest Tan Qiao from the Five Dynasties wrote the "Shu of Hua" which is exactly this. We regard this as a science, so it should naturally be called chemistry. What did Zhang Qian make?"

Guo Zi said: "This person was dedicated to gunpowder and made a new type of medicine to twist it out. It was a tube, which stored specially made gunpowder in the middle, which burned stably and could be timed like a fragrant carving. We tried many kinds of things to make pipes, and finally found that a kind of dry wood from the middle of the mountain was the most suitable. It was a thin tube, equipped with special gunpowder in the middle of the fire, and was loaded into a flowering bullet made of objects during the firing. As long as the artillery was calculated, the time could be calculated, and the medicine could be cut into the appropriate length. At this time, the cannon was accurately calculated and it could bloom when it landed, which was particularly powerful."

Du Zhongxiao nodded, not knowing what he should say for a moment. The requirement of bottom fire is very high, and Du Zhongxiao didn't even know the principle. Otherwise, if the bottom fire is created, these people can push into the post-gun era. The cannon must be said that once an explosion hurts people, it is completely two kinds of things.

After listening to Guo Zi's introduction, Du Zhongxiao said: "I didn't expect that in a few months, you made so many novel things. In this way, the war will be very different from what I thought before. Fortunately, the army was brought to the Iron Supervisor for drilling, otherwise wouldn't it be missed again? Since you have free time, you can go to the army to take a look and improve the military equipment based on the actual appearance."

Guo Zi nodded and agreed, and said, "Superior is an exercise for the entire army, can we try the Invincible Thunderbolt Vehicle? We have made many changes to this vehicle, reduced parts and added military weapons, which is extremely powerful. I report to the court, and the Privy Council attaches great importance to it. It is said that if this vehicle is very popular in the world, it will be against the northern cavalry, and there is no reason to be invincible!"

Du Zhongxiao smiled and shook his head: "Zhijian, I have never suspected that the car was useful, and I also knew that cavalry would inevitably be crushed into meat paste when it was opposite. But how to transport it? Such a large cart can only be transported elsewhere by railway, and run by itself. It can barely support it for 10 or 20 miles, but it will definitely not work even further. You have to add coal and water. How can you fight on the front line?"

Guo Zi hurriedly said, "There is nothing. We have tried it. The car is full and it is no problem to travel across five miles! With the small battlefield, those who take it within five miles will die, and they will be defeated. This benefit is worth using!"

Du Zhongxiao nodded repeatedly: "I know what you said is right, and I don't doubt it. But why not, let me explain it clearly to you. First, use a steam engine, and this car will definitely be small, unless it is flat, there are gullies, and ordinary bridges cannot pass through. In this way, the use of the battlefield will be limited, and it can only be used when facing the enemy head-on, which is better than the iron-armored cavalry. Another thing is that this kind of car is extremely expensive. If the army is in scale, it will consume too much money. Not only that, it also needs to be maintained at ordinary times, which is much more expensive than raising people and horses. The most important thing is to use this kind of car,

Whether it is a driving person or a fighting person on a car, you need professional talents. You have to learn and train them specifically, which is even more rare than excellent cavalry. If there are ten people on a car, they will probably be several times more repaired and maintained. These require reading and reading and reading skills. If it is expensive, money can be solved. Where can I find so many professional talents? As long as people are a little unfamiliar with them, it will be difficult to deal with them. Zhijian, this thing will definitely be on the battlefield in the future. It is right that you should put more effort into it. However, before the school was popularized, there were not so many talents and I dare not use them in the army."

The Invincible Thunderbolt Vehicle is a tank. Of course Du Zhongxiao knew it was very useful. However, the steam engine did not work for a long time and the ability to maneuver on the battlefield was not strong, which limited its use. In the era of cold weapons, using this method to defeat the enemy head-on was too cost-effective. If you cannot maneuver, you will lose the maximum function of the tank and cannot maneuver to pull the enemy's front line. After defeating, you will be unable to chase the enemy. This machine will become a threat. Not to mention such a car, its operators and complete sets of support require professional talents. What is most lacking in this era is talents.

Compared with neighboring countries, even if it is not considered factories like Iron and Supervision, the Song Dynasty was rich and belonged to a rich country. It was too much to use thunder chariots to spend money on the army. When the talent training system is formed later, the army is more professional, and it is not impossible to pile up money and throw people into money. At that time, on the northern grassland, there were overwhelming armored vehicles pushing over there, and no cavalry could stop it.
