If you want to do your job, you must first sharpen your tools.

The foundation of war lies in logistics, and the confidence of the army is also in logistics.

Adjacent to the river, outside a row of rammed earth walls made of loess, pieces of sulfur stones of different sizes are evenly spread out on the stone mill, and under the attraction of the waterwheel, the stone mill slowly rotates, pressing the sulfur into a fine powder.

All the craftsmen wore masks and hats to avoid burning their noses and ears with the unpleasant smell of sulfur.

In the gunpowder factory, countless craftsmen and helpers are busy.

In the production hall with the "primer" hanging on it, craftsmen are making "slow-burning gunpowder". The production of this brown gunpowder is much more complicated than the production of gunpowder, but it is necessary for the earth-shaking thunder.

The first batch of earth-shattering thunders developed shined in Jianling and killed all directions. Dong Ping is still praising it now. If there is no earth-shattering thunder, I don't know how many soldiers will have to be sacrificed to conquer the cottage.

The important weapon of the country, the source of confidence of the soldiers, and the foundation of breaking the enemy!

Thinking of the tragic situation of the day when the flesh and blood were flying and the flesh was blurred, everyone was terrified. Fortunately, this earth-shattering thunder is his own, and the lethality and use are obviously much better than bows and arrows.

The earth-shattering thunder made in the workshop uses gunpowder to blow up shrapnel to kill and injure the opponent, and the other is filled with iron balls and used to kill and injure the opponent.

But either way, it's so lethal that it's chilling.

"Daguan, you are really amazing, and the villain is really admired!"

Dong Ping came in and saw Wang Song in the workshop, so he hurriedly stepped forward with a smile on his face.

"Great officials, with these earth-shattering thunders, we are still afraid of a ball! The brothers are 100 each, and they directly killed Taiyuan Mansion and destroyed Yan Zonghan's house!"

"What Dong Ping said is true! After Yan Zonghan's dog's day, I want to see if his horse army is powerful, or my earth-shattering thunder is better!"

Zhang Heng was also quite excited, and directly burst into foul language.

"You two are speaking lightly!"

Deng Shixiong's black face suddenly became stiff, he is now in charge of logistics, and he naturally knows how much inventory and raw materials there are.

"All the sulfur powder and saltpeter in the storehouse combined, you can't make thousands of grenades! The soldiers still have to train, and there are two or three thousand left, which is already very good!"

Wang Song nodded and said: "Brothers, if you don't know the price of firewood and rice, you lack everything, it's useless to stare at it and be anxious, you can only come step by step."

Dong Ping and Zhang Heng glanced at each other and shook their heads, obviously regretful.

Speaking of which, although this "slow gunpowder" is difficult to make, it is simpler because of the small amount of materials.

The craftsmen found a 3-inch diameter willow firewood from the mountain. After steaming all day, the peel is peeled and dried, and then placed in a tin bucket. Each barrel is filled with 100 catties of willow firewood, and then baked for about half a day, and then the barrel mouth is sealed with mud, and after cooling, the willow firewood that becomes sauce color is taken out and ground into powder, which is the charcoal powder that constitutes chronic gunpowder.

This is followed by the treatment of nitrate and sulfur. 75 kilograms of nitrate are shared, and 4 kilograms of sulfur are mixed into powder after being dried into a semi-dry state.

After that, it's time to mix it. The craftsmen added 15 catties of charcoal powder to every 79 catties of nitrate and sulfur powder and stirred it into a medicinal material, and then sent it to the grinding pharmacy to be crushed on the stone mill. During the rolling process, the craftsmen added water evenly and continuously, just as they made granulated gunpowder.

After rolling, the craftsmen will crush the medicine cake into granules, press into a rice grain size medicine cake, each medicine cake must be 1 inch thick, 1 inch wide 3 minutes, weight 1 tael, 2 money 2 points, unqualified will be eliminated, shall not enter the baking program.

After the cake enters the baking pharmacy, it is dried in the shade at 15 degrees Celsius for 2-3 weeks before it can be packed, which is the delayed explosive of the grenade credit.

Although Wang Song can't make the same grenade as later generations, because of time, it is impossible for him to make a firepipe device in a simple way, and there is no way to make mercury thunderate.

But controlling the burning time and exploding after throwing it, such a simple explosive, the time of ten months, he is still sure.

Like the explosives bag he used last time in Killing Bear Ridge, it was used for the simplest explosives. When it is used, the gunpowder is tightly bandaged and blasted, and the power is already extraordinary.

Imagining countless earth-shattering thunders exploding on the battlefield, and countless golden iron horses being wiped out in the explosion, it makes people's blood boil when they think about it.

However, after thinking about it, I will eventually have to face the cruel reality, the lack of materials, the lack of silver, the shortage of craftsmen, and the backwardness of equipment, which may not be solved in a few years, or even decades.

During the Taiping Heavenly Kingdom, Yang Xiuqing used gunpowder blasting to break through Nanjing. At that time, the thickness of Nanjing's city wall was more than 15 meters, and the height was more than 10 meters, which can be said to be easy to defend and difficult to attack. At that time, there were only 5,000 Manchu soldiers in Nanjing, but it was these 5,000 people who fought against the hundreds of thousands of Taiping troops outside the city, relying on the extremely strong city walls.

The Taiping army besieged Nanjing, and concentrated all its artillery to carry out continuous artillery bombardment of the city wall, but with little effect, the city wall remained imposing. With nothing to do, Yang Xiuqing sent people to dig tunnels, until they reached the foundation of the Nanjing city wall, and used a coffin filled with gunpowder to seal and blast it, and blew down the impregnable Nanjing city wall, and finally occupied the city of Nanjing.

"Big guy, stop and listen to me!"

All the craftsmen and helpers stopped what they were doing and looked at Wang Song together.

"Everyone must remember that although this gunpowder burns slowly, it can also explode and hurt people. Therefore, everyone must be extra careful, everything is in accordance with the rules, and you must not be in a hurry, otherwise you will have to worry about your life!"

Everyone replied together: "Thank you for the teachings of the great officials!"

Liu San also said: "Don't worry, the big official, the villain must be cautious and there will be no accidents!"

Wang Song nodded and said, "Brother Liu, don't be sloppy, you must be careful!"

"Great official, you have to be careful with these things!"

Leaving the gunpowder workshop, Dong Ping let out a sigh of relief and said, "Once this thing explodes, it will be extraordinary!" The light ones are scarred and bloody, and the heavy ones are blurred and miserable. It's scary to think about!"

"This is the power of civilization!"

Wang Song said coldly: "Fanzi boasts that he is invincible!" If the two armies face each other, see if his cavalry is strong, or if my firearms are strong!"

"Firearms?"

Zhang Heng was stunned for a moment, and asked, "Daguan, apart from grenades, do we have anything else?"

"Not now, doesn't mean there won't be in the future!"

Wang Song's eyes were firm, and he said in a deep voice: "The grenade can maintain the balance of power at most, if you want to defeat the Jin people, in addition to training a strong army, you must also have better weapons as support." You'll find out later!"

Zhang Heng, Dong Ping, and Deng Shixiong all nodded. Although there were doubts in their hearts, Wang Song didn't say it, and they didn't have to ask again.

Wang Song smiled and said, "Brother Deng, let's go to the treasury and have a look." Brothers are going to fight, this armor is indispensable!"

Dong Ping had a deep understanding, nodded and said, "What the big official said is true!" In the battle of Jianling, fortunately, most of the soldiers wore armor, otherwise, there would have been not one or two hundred dead and wounded, but at least six or seven hundred!"

In the baggage storeroom, helmets are neatly arranged on the shelves, and it looks magnificent.

The soldier's helmet is still the model of the steel helmet at that time, which is also cast by iron fan, and the weight of two and a half catties is not heavy, and it is more than enough to protect the attack of the head.

However, if it is possible to create a cannon in the future, it is clear that heavy armor is not suitable for the gunners' frequent reloading actions, and leather armor will suffice. If the opponent is allowed to advance to a range of several tens of meters in front of the position, then it is tantamount to a military defeat.

The ironmaking of the workshop, the insulation design of the furnace, and the piston bellows were all applied. Naturally, the craftsmen were eye-opening, and it was much easier to craft weapons.

In addition to the main production of grenades, spears, and spear heads, there are also knives, short knives, armor, and lunch boxes and kettles cast by iron fans.

The shapes of lunch boxes and kettles are things that people often encounter in life, and Wang Song also modified them based on his own experience.

The lunch box is an iron lunch box with a lid, and the upper and lower buttons are simple and clear. The kettle fits perfectly, and the spout is polished smoothly so that it won't scratch the skin. Lunch boxes and kettles are loaded on the outside, which is convenient and durable, and easy to organize and carry when marching.

The lunch box and kettle are both designed to be 1 liter, the shape is about 10*15*19 cm, and the weight is one and a half pounds each. Both of them take into account the amount of water and food that the soldiers drink, are small and practical, easy to carry, and can greatly reduce the burden of the soldiers in wartime.

Deng Shixiong picked up a kettle, shook his head and said, "The big officials are really willing to spend!" One kettle per person, one lunch box per person, I'm afraid that the forbidden army of the imperial court is not so generous!"

Dong Ping rubbed a kettle with affection, and coldly admired: "Great official, you can also think of such a strange thing!" But this thing is really convenient to use, but it is too valuable!"

"What's so valuable about this!"

Wang Song shook his head and said, "Compared to the lives of my brothers, these things are worthless!" Only when people live can they fight each other. When a man dies, nothing can be done!"

Zhang Heng said sincerely: "Great official, you are really benevolent and righteous!" Brothers, follow you, and your hearts are open!"

Everyone walked forward, and the strange things in the warehouse made everyone dizzy.

The straight-handled cross pickaxe and straight-handled sapper shovel, Wang Song borrowed the 6411 series that was handed down in later generations, and the size was set at 70 cm, which was the same as that of later generations.

The pickaxe and sapper shovel are so easy to make that even ordinary craftsmen can build drawings that can be made.

Both the pickaxe and the sapper shovel are necessary for the sapper, and no one should be missing. There are thousands of miners on the Taihang Mountains, and they can pull up hundreds of people at will to build an engineering unit for digging trenches, building roads and bridges, and blasting.

Other than that. The Sapper role can also be used for explosives. This is the real ancient times, and in the future battles, there are not a few people who will destroy the city and uproot the village, and the sappers can be popular.

Wang Song raised his head, his eyes were long, and he didn't know what the war in Taiyuan was like now.

If it weren't as he expected, at this moment, the armies of the Great Song Dynasty were fighting with the Jin people one after another, and then falling apart.

And the woman in black, where has she gone now?

Thinking of the melancholy in the woman's eyes, Wang Song's heart moved inexplicably, and he became uneasy.
