When the Taoists got the materials, they worked hard, grind, mixed them, and stirred them until they were quite good.

Zhang Jun walked back and forth with a hot water bowl and looked over one by one.

He didn't say much, but asked them to follow their own methods, and wanted to see what they could do. What if there was a surprise.

The Taoist branches learned differently, and the ingredients used are also different. In addition to nitroxide, the carbon added is also different. Some are soap beans, some are aristolochic, and one is the most complicated one. They add realgar and honey.

This is a bit expensive. It seems that their school is relatively wealthy.

In fact, it is understandable that scientific research is just a process of accidental accidents, and coincidences outweigh design.

The same is true for the invention of gunpowder.

The reason why this kind of thing is called "medicine" is that it has been studied to cure diseases. In "Compendium of Materia Medica", it is mentioned that gunpowder can cure sores and ringworms, kill insects, ward off dampness, and eliminate plagues.

In fact, there was gunpowder since the Warring States Period. By the Tang Dynasty, it was quite mature, with skillful technology and relatively mature formulas. However, this thing was too dangerous. If you accidentally burned the house, you would not be popular among the mainstream.

Military, the history of using fire to cause trouble was earlier than gunpowder. Some grease and other things were tied to a stone cast or arrow to achieve the purpose of ignition. Among them, there is black turbulent oil, that is, oil.

At the end of the Tang Dynasty, gunpowder making techniques that were disliked by the majority of alchemists were discovered and learned by soldiers and started to be used in wars. They were mainly used to ignite fire, throw gunpowder over and burn materials or city gates, and the use method was relatively primitive.

The real technology was born in 1970. This year, a Ministry of War Lingshi named Feng Jisheng, invented the principle of rockets using gunpowder to generate powerful airflows, and pushed out the cluster of arrows to injure the enemy.

Does it look like the monkey in the sky? In fact, the monkey in the sky is an imitation of the Song Dynasty rockets, and the production methods and styles are basically similar.

By 1,000, the war utilization of gunpowder continued to escalate. Tang Fu not only upgraded and transformed the rockets, but also made more effective weapons such as fireballs and fire caltrops.

By the end of the Northern Song Dynasty, thunder cannons (cannons) and thunder (fire-induced grenades) had appeared.

In 1044, Zeng Gongliang edited the "Wu Jing Zongyao", which contains three mature gunpowder formulas, which are used for combustion, explosion and smoke.

During the reign of Emperor Shenzong of Song Dynasty, two firearms were set up to build, with nearly 10,000 workers. On the same day, 7,000 crossbow gunpowder arrows, 10,000 bow gunpowder arrows, 3,000 truncannons, and 20,000 leather guns.'

In 1161 of the Southern Song Dynasty, the thunder cannon was installed on the navy ships and used in the event.

In 1132, Chen Gui invented a musket, made of bamboo poles, filled with gunpowder, and sprayed to injure people.

In 1259, a sudden musket appeared in Shouchun area, spraying iron-sharp stones with gunpowder to injure the enemy.

In 1332, the rifle gun had developed into metal manufacturing, divided into artillery and fire system. Artillery defended the city, fire system attacked, and special shells (bullets).

In the Ming Dynasty, firearms developed in a further step, and they were already a regular military establishment. There were "fire crossbow meteor arrows" that could fire ten at a time and "hundred tigers running arrows" that could fire one hundred times at a time. The soldiers asked them to flock.

According to historical records, Emperor Yongle Zhu Di used this kind of swarm in the Battle of Baigouhe, won a great victory, and finally took up the throne.

There is also a record of the "Fire Dragon Out of Water". The rockets used on this warship are launched with gunpowder and can fly two kilometers four feet from the water surface, achieving the goal of winning a long-distance attack.

This is a secondary rocket. Single large arrows are used for flight. When the thrust gunpowder is burned out, the built-in small rocket is ignited for dispersed attacks.

There is also a kind of Divine Fire Flying Crow, which can basically be imagined as today's large-scale bundled launch vehicle. Except for the same small dot, it is a very reliable long-range multi-arrow tube attack weapon.

During the Western Expedition, Genghis Khan used a large number of gunpowder weapons.

In 1260, the Yuan Dynasty army failed to attack Syria and seized a large number of gunpowder weapons such as rockets, poisonous fire pots, artillery, and thunder. The Arabs mastered the manufacturing and use of gunpowder weapons.

Later, the Arabs began to use this Oriental artifact in a large number of battles with Spain, and then the Spanish learned to make and use them...and then the whole of Europe learned.

Firearms have been loved and pursued by Europeans because of their powerful lethality and long-range attack power, and have begun to develop rapidly.

Because of its powerful lethality and long-range attack power, the firearm was disgusted by the literati and the Qing dynasties in the late Ming Dynasty, and even prohibited its development.

...

‘Saltpeter comes out of the Long Road’, this is something that Zhang Jun is more satisfied with. The biggest problem of getting gunpowder by himself was arranged in advance by God.

He has also read many time travel novels, all of which go to the pit to collect and make nitrogen. Just ask, how many days can the people across the country use to shit together? How many can they create? It is simply unfair.

Several Taoist priests were busy working hard to finish their own works, each looking sweaty.

The main thing is that I am nervous. This is not very controlled. It is just a matter of saying that it cannot be put out. It is a trivial matter to light the house. If the Mansion Master is burned... Haha. The psychological pressure is quite great.

Fortunately, it was okay, it was cold and the Taoist priests passed the skills, so no accidents happened.

In fact, Zhang Jun was prepared for a long time and asked his personal soldiers to prepare the sand and soil. When it burned, it would be destroyed, which was to make a little smoke.

This is not the stupidity of the ancients, it is the difference between the times.

"Master, we have already made it."

Zhang Jun nodded, and slowly observed it one by one, looked at the color, smelled the smell, and picked it up with his hands a few times, and then he realized his mind.

"Come on, go outside for an interview." Zhang Jun asked someone to take the hemp paper, wrap the works of the Taoists in turn, and then take them to the yard outside to light them. The main thing is to see how different the results are from their estimates.

The chirping sound kept ringing, and soon, thick smoke rose in the government office. The personal soldiers in charge of ignition all turned a little dark and they were so choking that they coughed.

Most of these primary gunpowders burn quickly and then emit thick smoke. This is how Taoists usually coax the people, and it is not easy to choke them like this.

However, surprises are always sandwiched in the ordinary. One of them is a Taoist priest who uses Aristolochia. His works are not only burned, but also exploded. Although the effect is average, they are indeed exploded. With a bang.

Hemp paper is not modern paper. It is very thick and rough. You can imagine it as kraft paper. In fact, it is even tougher than kraft paper. Nowadays, paper containing hemp is no longer included, and only money is needed. It is illegal to make that.

The Taoist priest was also shocked. He had never wrapped it like this when he used it, and he himself didn't know that he could still fry it. The main reason was that he couldn't afford it, and hemp paper was very expensive.

Zhang Jun nodded with satisfaction.

He just realized that the proportion of things this guy made was very close to modern gunpowder, one to three. This thing cannot be written in detail because of 404, it just means that.

"Okay." Zhang Jun slapped his chin: "I am very satisfied. From now on, you will be the worship of our mansion. I will set you a visit."

"Xie Fuzun."
