From deciding to doing it to making things out, Song Beiyun worked for about a week.

During this period, except for accompanying Miaoyan to celebrate the New Year, I spent almost all the rest of my time with the most famous blacksmith in Jinling City.

The conscience-free cannon does not require accuracy or structural strength. If the structural strength is not required, it means that seamless steel pipes are not needed. After the iron sheet is circled, then poured with iron, and wrapped with rivets and tung oil vines for a few rounds. The foundation strength is completely beyond the rusty gasoline barrel.

Song Beiyun made this thing on the first day, and then tested its ejection ability and its specific effect under the action of different explosives.

First of all, it is certain that black gunpowder must not damage this container, but the power is too urgent. The remaining residue is scary. It needs to be cleaned up after a few times. Then there are thunder mercury and nitrosol. These two things have similar effects, but their power is really a bit snatching the feet. The longest range is less than fifty meters, which is simply a magical weapon to kill one thousand enemies and damage one thousand eight. If you face cavalry, these fifty meters are enough for people to surround the face.

Then there is the double-based explosive. This effect is good, but the chemical properties of the double-based explosive are really unstable. There is absolutely no problem for Song Beiyun to operate, but if the enemy does not see it, the base camp will be gone first.

So in this case, he didn't want to try the same unstable nitroglycerin and picric acid streams.

In the end, Song Beiyun could only use his few TNTs with heartache, which was very effective. The only disadvantage was that if the charge was not controlled well, the iron barrel would explode directly, and no grass would grow in a radius of ten meters.

Just for the amount of charge, Song Beiyun almost used all the remaining tnts. There was also a strange legend in Jinling City these days, which was that thunder thunder broke out in the deep mountains. It was supposed to be that the mountain god was fighting with the evil ghosts.

After determining the charge of TNT, Song Beiyun customized twenty such barrels, and then tried his best to start making TNT. But how much production capacity can a person be? Even if he works overtime, he can only meet the materials needed for the experiment the next day.

Afterwards, he tested the conscience-free cannons to shoot iron slag, iron slicing, porcelain slicing, stone and bamboo wood. Then the porcelain slicing and bamboo wood were completely rejected. The sputtering range of the slicing pieces was too large, which could easily hurt his soldiers, while bamboo wood was pure and funny.

Of course, the effect is naturally the best way to shoot the explosive pack. TNT can throw the explosive pack to a distance of about 200 meters. After padding a wooden board to increase the chamber pressure, it can even reach a distance of 350 meters. After the explosive pack explodes, its lethality may be average, but the sound and light effect is very amazing. He has already left Jinling City for five kilometers, but the city gate guard can still clearly hear the explosion.

This means that horses are absolutely unable to adapt to such fright. If you want to improve the model, the outer periphery of the explosive bag can be wrapped in iron sheets, and the cracked porcelain and ceramic pieces can be filled in the gaps, which can not only save explosives but also cause killing effects.

Projectiles such as iron sheets and iron slags can actually be used as close-defense weapons. When the opponent's infantry approaches, this kind of scattered flower that does not require accurate heads is enough to eliminate the opponent's large amount of vitality in a short period of time.

In order to test its killing effect, Song Beiyun even stole a set of stairs and human armor from the city defense force armor. Within forty distances of the explosion range, metal shrapnel could directly penetrate the stairs and human armor to kill the internal structure, and even within twenty meters of the range, it would even cause penetration injuries. Even if it was fifty meters away, it still had a terrifying killing effect on light armor.

In addition to physical attacks, Song Beiyun also tested the White Phosphate Oil Inflammation Bomb, White Phosphate Poison Gas Bomb, Sulfide Poison Gas Bomb and Black Powder Barrel. He also decisively abandoned all the poison gas bombs, because the thing was blown by the wind and killed 600 enemies and damaged 13,000.

As for the black powder keg, the biggest disadvantage is that it is difficult to grasp its explosion time, and the fuse is prone to problems during ejection, so the overall effect is not as easy as TNT.

However, there is something good about it, that is, the overall cost of black gunpowder is so cheap that it is unbelievable. Even the storage of relevant materials in the Da Song warehouse is enough to produce a large amount of black gunpowder.

So whether black gunpowder is useful is definitely useful. For example, if you are given a hand cannon to each soldier, it can play an absolutely beyond imagination during close combat. People are still whining up with big swords and rushing upwards twenty meters away. With a bang, they kill one, and the effect is outstanding.

Of course, all of this design solutions are substitutes before the emergence of seamless steel structures. Song Beiyun didn't know when he would be able to make seamless steel pipes, but before these things, he could not make any achievements, right? At least three-year agreements can be used to pass on this thing.

However, the biggest problem now is production capacity. Failure to keep up with it and confidentiality is also a big problem. Some things cannot be made. Just like everyone has black gunpowder, there is a fundamental difference between black gunpowder that can explode and black gunpowder that can only be sniffed. Even if the enemy does not use it to deal with people, just for adaptive training, the effect of the surprise weapon will be greatly reduced.

Therefore, confidentiality and production capacity have now become Song Beiyun's urgent need.

"You haven't shaved your beard for a few days." Today it was Miaoyan's turn to come to the mountain to deliver food to Song Beiyun. She put the things in the basket on the small wooden table and sat next to Xiao Song: "I have made myself a savage."

"There is no time? I am the only one who is busy all over the past few days. I am almost vomiting blood." Xiao Song pointed to the thatched hut behind him: "You don't even look at my living conditions."

"Be careful, don't blow yourself up." Miaoyan walked up and patted the conscience-free cannon that smelled of gunpowder: "But I still want to give you a thumbs up. This thing is simply unsolvable to fight cavalry."

"Machine guns are the ultimate kingdom, but guns are much more difficult than cannons. Just a rifling process is impossible to do now." Song Beiyun shook his head and said, "Not to mention the metal fixed loading, I am too proud of the ancient production level."

"Take it slow, you've pulled them apart for hundreds of years now." Miaoyan smiled and said, "At least what you're spraying out is an explosive or not a solid projectile."

Song Beiyun picked up the bowl and started eating. Halfway through the meal, he looked up at Miaoyan: "Can this three thousand cannons be used to attack 200,000 cavalry?"

"Who knows this? The battlefield is the place to test weapons. It is hard to say on paper. But I think it's OK." Miaoyan smiled and pinched Song Beiyun's face: "Things you haven't seen before will always make people feel afraid. Maybe there are people who are not afraid of death, but there are definitely no horses who are not afraid of death."

Well, Miaoyan's view coincides with Song Beiyun's view in this regard. The greatest effect of a conscience-free cannon is its deterrence effect. Three thousand cannons are fired in one round, even 500,000 people will be scared. What's more, the cavalry of this era is single tactics and lacks effective long-range weapons. It is difficult for the crossbow to cause any major casualties to the fixed position when it is prepared. However, chaos and trampling will inevitably occur when the cannon is fired.

"With long-range weapons, positional warfare is a very good choice. Highlands, flat grounds and even depressions can produce different effects." Miaoyan started drawing trenches on the ground with a small stick: "Long-range firepower strikes the opponent's vanguard cavalry, paper trenches strike the opponent's main force, and 5,600,000 people fight 200,000. It's not a big problem when there is sufficient ammunition."

Song Beiyun nodded repeatedly, took a deep breath and leaned against the dead wood behind him: "Now, wait for the production capacity to rise, and then we have to find a suitable person to practice and see how the actual combat ability of the unconscience-free cannon is like."

"Well, I don't understand this, you can do it. Should I create an opponent or conduct military exercises?"

"There is no use for military exercises. Of course, it is to get an opponent out." Song Beiyun scratched his chin: "I have an idea. Starting tomorrow, how about we have a big evaluation of Song Beiyun's skilled craftsmanship?"

"Oh? Start the industrial draft?"

"Of course, the status of craftsmen is very low, but I need more skilled workers and high-quality technical workers. There must be brave men under the rewards. Let's buy horse bones with a rich fortune."

"Aren't you afraid that those scholars will say you are forming a clique for personal gain?"

"Hi..." Song Beiyun waved his hand: "If I go to win over the powerful people from all sides, maybe someone else would say that I would have a few craftsmen, but they wouldn't bother to take a look at them. The status of scholars, farmers, industry and craftsmen is so low that they are scary. Now merchants are starting to look up, but craftsmen are becoming less and less in status."

"Because you don't fight, is that?"

Song Beiyun did not comment and leaned on the other side to eat while thinking about how to operate the first draft of the Song Dynasty Industrial Empire.

The Song Beiyun series rewards that made Song Song beg for is about to set sail. If it can be successful, technology will definitely be led by the East in the next thousand years. How happy this is, even Song Beiyun can't wait.

"Don't be rushing and excited, I'll pour cold water on you." Miaoyan said with a smile, holding her knees, "The literacy rate of the craftsman class is low, and empiricism is prevalent, which means that they are actually a relatively stubborn group. In addition, this era does not value craftsmen, which leads to their morale being sluggish. You must first find a way to solve this problem and how to make them burn."

Song Beiyun nodded and said, "Well, it's a bit difficult."

"But you do it first, some things cannot be solved by sitting here and patting your butt. You can cross the stage from scratch from scratch before you can go from existence to essence."

Comrade Xiao Song didn't say anything for a long time, but he just thought in his heart how to start this operation, and it is probably not just the working class who really wants to change...
