Gunpowder has been around for a long time, as early as the Spring and Autumn Period, people have been in the hands of Fangshi, gunpowder has been made.

However, in the beginning, gunpowder was used as a medicine to treat a variety of diseases such as stomach pain, sores, scabies, and nameless swelling and pain.

The term gunpowder first appeared in the time of Song Renzong, Zeng Gongshun compiled the "General Essentials of the Martial Arts", the term gunpowder appeared for the first time, and the formulas of three types of military gunpowder were publicly recorded.

Unfortunately, this did not go unnoticed by the vast majority of people.

The conventional method is Song Renzong's method called the Fuhuo sulfur method to burn gunpowder.

The method is to burn two taels of sulfur, two taels of saltpeter, and three soaphorns together, and wait until the soaphorns are burned, and then put in three pieces of charcoal, stir-fry, and officially out of the pot.

In fact, the invention of gunpowder began in the Spring and Autumn Period, and in the Jin Dynasty, gunpowder had already been used on a considerable scale, and by the Tang Dynasty, gunpowder had been mastered by almost most alchemists.

And in the folk formed an industrial chain, Bianjing's fireworks are extremely bright.

However, these three gunpowder formulas were not officially taken seriously by the Song Dynasty until after the invention of iron artillery in the Jin Kingdom.

It turns out that gunpowder can still play like this.

Taoist alchemy led to the invention of gunpowder, of course, Taoists alchemy, alchemists for immortality. Therefore, the military use of this gunpowder has not been taken seriously.

Taoism has a wide influence on folk sacrifices, spells, and social mores.

Zhao Huan once saw a sentence that people often hate monks, nuns, Muslims, Jews, and Taoists. Those who understand this principle understand most of China.

Therefore, gunpowder has always been advancing with China. It didn't stop.

What was the gunpowder used for in the Great Song Dynasty?

Acrobatic performances used in the circus of the armies, as well as pyrotechnic acrobatics in puppet shows - medicine puppets. This is the main use of gunpowder.

Acrobatic shows such as "Holding Gongs", "Hard Ghosts", and "Pantomime Dramas" all use the newly emerging gunpowder products such as "blasting battles" and "spitting fire" to create a mysterious atmosphere.

At the same time, the Song people also used gunpowder to perform illusions, such as spewing out fireworks and clouds to escape people and change objects, etc., in order to obtain the effect of magic and confusion.

The Great Transformation was born in the Song Dynasty, but unfortunately militarily, gunpowder has always been overwhelmed.

On the basis of the fire and sulfur method, the outdated gunpowder has been further transformed, and the formula has been further improved.

No technology can be achieved overnight, and even Newton needs to stand on the shoulders of giants.

And because of this, Zhao Huan can't take out the production method of TNT and use it directly.

After all, if you hold a high math book and don't go to class, don't you still have to take the make-up exam?

Of course, as far as advanced mathematics is concerned, if you attend classes and listen carefully, you don't necessarily have to take a make-up exam.

Just like high mathematics, the manufacture of gunpowder has a great deal to do with one's qualifications.

Therefore, Zhao Huan must find someone and find the gunpowder foundation of the Great Song Dynasty in order to further improve the power of gunpowder.

Only by building a house on the foundation can the house be built higher.

"You fumbled for this gunpowder yourself?" Zhao Huan asked, twisting gunpowder in his hand.

Obviously, this kind of gunpowder cannot be used as a firing charge for muskets, but it is obviously not enough to make gunpowder for explosives packs.

"The official family, the original Guangbei siege work, 7,000 sunrise crossbow gunpowder arrows, 10,000 bow gunpowder arrows, 3,000 tribulus cannons, and 20,000 leather artillery, and then the emperor issued an order to supervise the construction of long soldiers, so the gunpowder was stopped." Li Gang whispered, reminding the official of the output of gunpowder.

Zhao Huan didn't complain too much about Song Huizong Zhao Ji's decision, because if it was Zhao Huan, he would also stop this unreliable gunpowder work.

The tribulus terrestris cannon is not a cannon, it is the same as the explosive bag that Zhao Huan prepared to make, it is a gunpowder bag containing barbed iron sheets. [Note 1]

But all this is based on the quality of gunpowder, for example, the gunpowder in front of you, there is more than half of the dumb fire, this on the battlefield, isn't it a joke?

Counting on the same retarded minds as the Jin people and the bandits? Frightened by the sound of gunpowder and the light of fire?

"I'm looking for it, the last time I left, I wrote a note about the gunpowder he had improved, where did it come from? Over here! Zhao Huan searched for a long time in his wide sleeve and took out a notebook.

In fact, he was just changing the manufacturing process and process of black powder.

The remaining question of how to kill the enemy more effectively is a problem that Liu Yi, Su Xian, and Chen Gui should consider.

Of course, looking at the information of the tribulus cannon, Zhao Huan also believed that the Song people would not let themselves down, they just lacked high-quality gunpowder.

"Kind of Shaobao even took this into account? Sure enough, it's a kind of undergrowth! Li Gang said with a frown.

Zhao Huan had a smile on his face, of course this was not written by the Seed Master, but he redeemed it from the system's achievement points mall.

Of course, it's not as simple as memorizing the formula like one nitrate, two sulfur and three charcoal, and you can say it, how to do it?

How to deal with it, and to what extent? All need strict regulations!

"Preliminary Study of Brown Gunpowder" is a notebook taken out by Zhao Huan, he handed it to the old rules, the method is not long, and it is almost the same as the operation of the old rules, but the specific process is standardized.

In fact, this was originally called "Hexagonal Seven Hole Maroon Gunpowder Forming Technique I".

Chen Gui took it and glanced at it, the surprise in his eyes became heavier and heavier, and said, "Official, wait a while, the minister will come when he goes." ”

Compared with the outdated rough work, coarse materials, and coarse tools, the methods given by Zhao Huan have more technologies such as nitrate, sulfur, grinding, pressing, granulation, and drying.

Zhao Huan didn't wait for a moment, but followed the old rules into the gunpowder work.

Liuchai is pre-treated.

After sizing and degrading, it was fumigated for a whole day, and after taking out, the willow firewood was steamed for a whole day, the willow skin was peeled, and it was baked in an iron barrel for six hours. After the sealing mud is naturally cooled, it is now the raw material of willow firewood in the hands of Chen Gui.

Chen Gui took out the stone mill, put the prepared willow firewood into the stone mill, and crushed it into powder.

Begin to process saltpeter and sulfur, dry and mix, start mixing, saltpeter 75 taels, sulfur 10 taels, charcoal 15 taels accurately weighed, and grind again.

It is the formula of mononitrate, disulfur and charcoal.

"Official, do you want to add water here?" Chen Gui suddenly stopped, glanced at "First Exploration" and asked.

Washed gunpowder? Can it still be like this? Chen Gui looked at this step and had some doubts.

Zhao Huan nodded and gave Chen Gui an affirmative answer, it was written in the notebook, if you want to figure out what's going on, you have to rely on Chen Gui to understand it yourself.

The stereotype began to mix the medicine with water and wash the mixture, and the black-brown medicine in his hand turned into granules.

After that, the old rule did not stop, but took out the sieve, adjusted the size of the holes in the sieve, and removed the powder.

"Graphite powder! Fetch me fifty taels of graphite powder! The old rule shouted loudly, and soon someone brought the graphite, and the graphite powder was to be polished.

When the medicine was pressed, the medicine finally became a medicine cake about one inch thick, one inch and three points wide, and one or two cents and two cents in weight.

At this time, the old rules did not stop, but took out the scale, began to weigh, all the medicine cakes that did not meet the requirements, all discarded, the weight is wrong, proving that the material is wrong.

In the end, Chen Gui got fifty pieces of medicine cakes, he carefully took the medicine cakes, put them in the baking pharmacy, and said with blazing eyes: "Official, this time it will definitely work!" ”

"Chen Shaoqing, the constantly changing ratio of saltpeter, sulfur, and charcoal can get other types of gunpowder, and you will make new discoveries if you try more." Zhao Huan said with a smile.

This is just a preliminary exploration, the gunpowder made is just making the bomb powder of the tribulus terrestris cannon, and there will be iron pieces inserted into each medicine cake, and when it is detonated, the iron pieces are shot everywhere, and the scene is not too good-looking.

Zhao Huan looked at the musket in the corner of the wall and said: "Chong Shaobao once said, eighty taels of nitrate, four taels of sulfur, and sixteen taels of charcoal, you can get gunpowder, and the color of chestnuts is bitter, Chen Shaoqing can try it." ”

This is the formula of the triggering medicine, Zhao Huan did not wait for the stereotype to try, and said the formula of the triggering medicine. The rest is in the first exploration of this notebook, waiting for the stereotypes to slowly grope for it.
