From deciding to do it to making things, Song Beiyun worked for almost a week without sleep or food.

During the period, except for accompanying Miaoyan for New Year's Eve, the rest of the time was almost soaked in the most famous blacksmith in Jinling City.

There is no conscience cannon, it does not need accuracy and structural strength, and the lack of structural strength means that there is no need for seamless steel pipes.

Song Beiyun got this thing out on the first day, and the next step was to test its projectile ability and the specific effects under the action of different explosives.

First of all, it is certain that the black powder will definitely not be able to damage this container, but the power is not to mention that the remaining residue is also too scary, and it needs to be cleaned up after a few uses. After that, there is thundermercury and nitrocellulose, these two things have similar effects, but the power is really a bit picky, the longest range is only less than fifty meters, it is simply an artifact that kills a thousand enemies and loses one thousand and eight, if you face a cavalry, these fifty meters are enough for people to outflank the horseman's face.

Then there is the double-base explosives, which has a good effect, but the chemical properties of the double-base explosives are really unstable, and it is absolutely no problem for Song Beiyun to operate them, but if they are operated by those big-headed soldiers, the enemy will not see it, and the base camp will be gone first.

So in such a situation, he didn't want to try the same unstable nitroglycerin, picric acid, etc.

In the end, in desperation, Song Beiyun could only use his few TNT in distress, the effect was great, the only drawback was that if the charge was not well controlled, the iron bucket would be directly exploded, and there would be no grass within a radius of ten meters.

For the sake of this charge, Song Beiyun almost used all the remaining TNT, and there is also a strange legend in Jinling City these days, that is, there is thunder in the deep mountains, and it is thought that the mountain god is fighting with evil ghosts.

After determining the amount of TNT, Song Beiyun went to customize twenty more of these barrels, and then used all his strength to start manufacturing TNT, but how much production capacity can a person have, he can only meet the materials required for the next day's test even if he works overtime.

After that, he successively tested the unconscionable cannon throwing iron slag, broken iron, broken porcelain, stone, and bamboo wood, and then the broken porcelain and bamboo wood were completely rejected, the sputtering range of the broken porcelain was too large, and it was easy to hurt his own soldiers, and the bamboo and wood were purely funny.

Of course, the effect is naturally the best projectile explosive package, TNT can throw the explosive package to a maximum distance of about 200 meters, pad a wooden board to increase the pressure of the chamber can even reach a distance of 350 meters at one time, and so after the explosive package explodes, its lethality may be average, but the sound and light effect is very amazing, he has left Jinling City five kilometers, but the city gate guard can still clearly hear the sound of explosion.

This means that the horse is absolutely unable to adapt to such a fright, and if the model is improved in the future, the periphery of the explosive bag can be wrapped in iron, and the gap can be filled with broken porcelain and pottery shards, which can not only save explosives but also cause personnel to kill people.

And projectiles such as iron sheets and iron slag can actually be used as close defense weapons, and when the opponent's foot soldiers arrive, this kind of heavenly maiden scattered flowers that do not need to be accurate are enough to destroy a large number of living forces of the opponent in a short period of time.

In order to test its killing effect, Song Beiyun even stole a set of infantry armor from the armory of the city defense army, within forty distances of the explosion range, the metal shrapnel can directly penetrate the infantry armor to kill the internal structure, and within twenty meters it will even form a penetrating injury, and even if it is fifty meters away, it still has a terrifying killing effect on light armor.

In addition to physical attacks, Song Beiyun also experimented with white phosphopine oil incendiary bombs, white phosphorus poison gas bombs, sulfide poison gas bombs, and black powder kegs. And decisively threw away all the gas bombs, because the thing was blown by the wind, killing 600 enemies and losing 13,000 themselves.

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 when ejected, so the overall effect is not as good as TNT.

However, it is not without merit, that is, the overall cost of black powder is unbelievably cheap, and the storage of relevant materials in the current warehouse of the Great Song Dynasty is enough to make a large amount of black powder.

So whether the black powder is useful or not, it must be useful, for example, each soldier is issued a hand cannon, which can play an absolutely unimaginable role in close combat, and people are still whining and rushing up with a big knife twenty meters away, and this snap will kill one, and the effect is outstanding.

Of course, all these design plans are built on the replacement of the seamless steel structure before the emergence of the seamless steel structure, Song Beiyun doesn't know when he will be able to toss the seamless steel pipe this thing, but without these things, it can't be without achievements, right? At least a three-year covenant can be passed with this thing.

But now the biggest problem is the production capacity, the production capacity can not keep up and the secrecy is also a big problem, there are some things they can't make, just like black powder although everyone has it, but there is a fundamental difference between the black powder that can explode and the black powder that can only be used to make a big flower, even if the enemy does not use it to deal with people, just for adaptive training, the effect of the strange soldier will be greatly reduced.

Therefore, confidentiality and production capacity have now become Song Beiyun's top priorities.

"You haven't shaved your beard in days." Today, it was Miao Yan's turn to bring food to Song Beiyun in the mountains, and she sat next to Xiao Song after putting the things in the basket on the small wooden table: "I have tossed myself into a wild man." ”

"How can I have time, I've been alone up and down these days, and I'm so busy that I'm about to vomit blood." Xiao Song pointed to the thatched house behind him: "You don't look at my living conditions." ”

"Be careful, don't blow yourself up." Miao Yan stepped forward and patted the conscienceless cannon that smelled of gunpowder: "But I still have to give you a thumbs up, this thing is simply incomprehensible to the cavalry." ”

"Machine guns are the ultimate king, but guns are much more difficult than guns, and a rifling process alone can't be done now." Song Beiyun shook his head and said: "Not to mention any metal fixed ammunition, I think too highly of this ancient production level." ”

"Take your time, you've been pulling them apart for hundreds of years now." Miao Yan smiled: "At least what you sprayed out is an explosive, not a solid projectile." ”

Song Beiyun picked up the bowl and began to eat in a loud manner, and halfway through eating, he raised his head and glanced at Miao Yan: "Three thousand cannons, can you fight 200,000 cavalry?" ”

"Who knows, the battlefield is the place where weapons are tested, and it is impossible to say on paper. But I think so. Miao Yan smiled and pinched Song Beiyun's face: "Things that I haven't seen always make people fearful, maybe there are people who are not afraid of death, but there is definitely no horse who is not afraid of death." ”

Well, Miao Yan's point of view and Song Beiyun's point of view coincide in this regard, the biggest effect of the conscienceless cannon is the deterrent effect, three thousand cannons are fired in one round, even 500,000 people have to be frightened, not to mention that the cavalry tactics of this era are single and lack effective long-range weapons, it is difficult for the bow and crossbow to cause many casualties to the fixed position in the case of defense, but as soon as the cannon sounds, chaos and stampede will inevitably occur on the opposite side.

"Positional warfare is a very good option when you have long-range weapons, and you can play different effects on high ground, flat land, and even depressions." Miao Yan used a small stick on the ground and began to draw the appearance of the trench: "Long-range fire strikes the opponent's vanguard cavalry, and the roundabout trench strikes the opponent's main force, five or six thousand people fight two hundred thousand, and it is not a big problem when there is enough ammunition." ”

Song Beiyun nodded again and again, took a deep breath and leaned against the dead wood behind him: "Now I have to wait for the production capacity to rise, and then I have to find the right person to practice and see how the actual combat ability of the conscienceless cannon is." ”

"Well, I don't understand this, you can do it. Is it to create an adversary, or to conduct military exercises? ”

"The military exercise has a fart purpose, of course, to get an opponent out." Song Beiyun scratched his chin: "I have an idea, starting tomorrow, how about let's get a Song Beiyun skilled craftsman competition?" ”

"Oh? Starting an industrial draft? ”

"Of course, the status of craftsmen is very low, but I need more skilled workers and high-quality skilled workers. There will be brave men under the heavy reward, let's buy horse bones for a thousand dollars. ”

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

"Hey ......" Song Beiyun waved his hand: "If I go to win over the powerful from all sides, maybe some people will say, I will get a few craftsmen, and people will not bother to look at them. Now the merchants are beginning to raise their heads, but the craftsmen are becoming less and less statused. ”

"Because there is no war, do you?"

Song Beiyun was noncommittal, leaning over there to eat while thinking about how to operate the first draft of the Great Song Industrial Empire.

Let Xiao Song's heart miss the Song Beiyun series of rewards is about to start sailing, if it can be successful, in the next thousand years, science and technology will definitely be led by the East. This is so gratifying, even Song Beiyun can't wait.

"Don't be too excited, I'll pour cold water on you." Miao Yan hugged his knees and said with a smile: "The low literacy rate of the artisan class and the prevalence of empiricism mean that they are actually a relatively rigid and self-serving group, and this era itself does not reuse craftsmen, so it causes their morale to be sluggish, you must first find a way to solve this problem, how to make them burn." ”

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

"But you do it first, there are some things that you can't just sit here and pat your butt. You have crossed the stage of going from nothing to something, and then you can go from having to refining. ”

Comrade Xiao Song didn't speak for a long time, but secretly thought in his heart how to start this set of operations, and it is probably not only the working class that needs to change......
