"Firearms!"

The number of weapons placed in the courtyard is already surprising, these things are prohibited by the imperial court, and once they are found out, it will inevitably be troublesome. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Zhu Yuanzhang once received the grace of martial arts people, and he also knew the personality of the people in the rivers and lakes, and they liked to be heroes one by one, and they were uneven, so it was good, some things the power of the imperial court could not be taken into account, and they could only rely on these people to complete, so they set up a special martial arts division to manage the various major sects, and the number of sects and the number of weapons had special records, and from time to time someone would check it, and they had been safe and sound all these years.

Lin Feng is naturally no stranger to firearms, the firearms of this era are many times different from his own era, although they are all gunpowder, the process is too different.

At the beginning of the Ming Dynasty, Zhu Yuanzhang continued to take various effective measures to develop weapon manufacturing, and standardize and unify the primary firearms created in the Yuan Dynasty, and develop them into a Hongwu series of firearms including large, medium and small according to the needs of actual combat.

According to the size, structural characteristics and combat use of the Hongwu series of firearms, they can be divided into three categories: one is equipped with handguns for individual use, the second is the medium-sized bowl-mouth guns equipped for warships and pass guards, and the third is the large guns specially used for city defense fortresses.

At this time, in Lin Feng's hand was the most delicate handcuff, the smaller the scale, the higher the requirements for craftsmanship, the slender body, the breech was cylindrical, and the projectile was placed inside. The medicine room is spherical and bulging, and there is a fire door on the wall of the chamber for placing the lead for ignition. The tail chisel is hollow and can be equipped with a wooden handle, which is easy for the launcher to handle.

Gunpowder is one of the four great inventions of ancient China, which is still a source of pride for the descendants of Yan and Huang, and it is recorded in the dictionary that gunpowder - invented by the Chinese, is a mixture of sulfur, potassium nitrate and charcoal, and was first used by the Chinese as an arson agent for fireworks, firecrackers and rockets.

It may not be taken seriously in the eyes of modern people, but when science is still in obscurity, gunpowder is a mysterious thing. There is a story in the "Taiping Guangji": a young man named Du Zichun, in order to seek the art of alchemy, went to a secluded and distant place to meet an old alchemist. It was getting late, and the old man told him to rest in the place of alchemy, and told him not to talk nonsense.

At night, Du Zichun woke up and found that the alchemy was on fire, the flames were rushing upward, he remembered the old man's warning, and remained motionless, watching the flames burn to the roof and burn the house. From this, one can imagine the name "gunpowder", which means "the powder that is on fire". This is the first property of gunpowder that people recognize - combustion.

And because the main ingredients in gunpowder, nitrate and sulfur, were used as medicines in the Western Han Dynasty to treat diseases, and the ancient alchemists in order to refine the "elixir of life", all year round seclusion in the mountains, carefully selected a variety of pharmaceutical raw materials, repeated refining, many experiments, in their hard work, although did not get the elixir of immortality, but found and invented many little-known things.

Gunpowder is a great result of the hands of alchemists. At that time, the doctrine of "fairy way" was prevalent, so gunpowder got its name from the medicine.

Although the power of firearms is amazing, the disadvantage is that gunpowder refining is relatively dangerous, a little careless, there will be an explosion, every time a firebomb is issued, it takes a certain amount of time to load the ammunition to launch, the accuracy of the firearm can not be guaranteed, and it invisibly affects the use of firearms. Therefore, this kind of firearm is only available in the border areas or among the defenders of the capital.

"Brother Lin, what the hell is this?"

"Firebolt, use the power generated by the explosion of gunpowder to hit the ammunition hidden inside, don't underestimate it, it will shine in the future."

Tang Niu stretched out his hand to take it, turned it over and looked at it carefully, but still didn't figure out the doorway inside, "Brother Tang is saying that there is still such a thing in the Heaven and Earth Alliance?" ”

"Can't be wrong, when I saved the Wu gang leader, there were disciples who were guarding the door with this kind of thing, and they almost suffered a big loss, if it wasn't for Erniang's timely action, I'm afraid I would have to make a big mistake this time."

Lin Feng nodded, the white stones and charcoal found from the side yard, the black and white are particularly eye-catching, of course, the most critical thing is indispensable, sulfur, Long Tian is very smart, the side yard is extremely remote, and it is a place where criminals are kept, and few people approach it on weekdays, so it is convenient for the Heaven and Earth Alliance to build weapons and firearms.

As early as the Neolithic period, people learned about charcoal when they fired pottery and used it as fuel. During the Shang and Zhou dynasties, charcoal was widely used in metallurgy. Charcoal has less ash than firewood, has high strength, and is a better fuel than firewood. Sulfur is naturally present and has been mined for a long time. People are often exposed to sulfur in their daily life and production, such as the smell of sulfur released from hot springs, and the pungent smell of sulfur dioxide escaping from metal smelting. The ancients mastered the earliest nitrate, may be the corner of the wall and the root of the house under the soil nitrate, the chemical properties of nitrate is very lively, can react with many substances, its color is not much different from some other salts, it is easy to make mistakes in use, in practice people have mastered some methods to identify saltpeter.

"Go in and have a look."

Lin Feng was in front, Wu Ying and the others followed behind, and entered the side courtyard again, the things piled up inside had been emptied, and the originally crowded space became empty, judging from the space, there was no abnormality, with the experience of the desert line, the concept of space was strengthened, as long as you glanced at it, you can judge the size of the space inside by the thickness of the wall.

"Look for it and see if there's a mechanism."

"Okay."

The crowd quickly parted and walked along the walls, which were covered with green moss, and the raw materials used to make the gunpowder were flammable, so there was no sunlight all year round, and the air was filled with the smell of sulfur and human excrement.

Lin Feng's palm landed on it, making a dull sound, and he kept moving forward along the way, until he came to the position where Wu Tianxiong was held that day, in a small space, those bloody iron chains were thrown on the ground, and the ground was even more filthy.

"Gang Leader Wu, I was trapped here that day, did you hear some strange sounds?"

"Yes." Nothing was found, under Lin Feng's reminder, Wu Tianxiong suddenly remembered something, this unbearable memory originally didn't want to mention, "One night, suddenly the whole ground shook for a while, and then there was a thunderclap sound below, just like the sound of popping beans, because it lasted for a short time, so I didn't take it to heart." ”

"Underground!"

Lin Feng nodded, that's right, Long Tian is an ambitious person, using the Heaven and Earth Alliance to constantly annex other sects, and secretly building weapons is the best example, but unfortunately Long Tian is dead, and there is no way to figure out how big his ambition is, what is the ultimate goal of building weapons and firearms, if it is just to dominate the martial arts, these alone are still far from enough.

At this moment, everyone's attention is on their feet, which is also the place where people are most likely to ignore, boom, Wu Tianxiong accidentally kicked the iron chain, at this time the strength has recovered eighty, thinking of the humiliation suffered in those days, he grabbed it violently, and pulled it outward with both arms, quack, this kind of iron chain has been built by a special process, it is strange to say, as the iron chain is straightened, the wall on the side changes.

"One more time."

Wu Tianxiong's face was slightly red, Tang Niu came to the front with an arrow step, exerted force with his arms, and finally saw that as the iron chain was pulled out, a brick on the wall on the side was sunken inward.

Lin Feng nodded, a figure approached, the long sword in his hand pierced in, quack, quack, a strange sound sounded, followed by a shaking of the ground, this feeling should be almost the same as what Wu Tianxiong felt in the dark, who would have thought that Long Tian would put the organ in the place where Wu Tianxiong was imprisoned.

Wu Tianxiong suddenly realized, "Those people will blindfold me after being tortured, and I was too sleepy at that time, so even if someone enters from here, they will not be able to find out." ”

As the sound disappeared, a pitch-black hole appeared in the corner of the wall, enough for a person to bend over, and the Heaven and Earth Alliance was built on the mountain, and it was not difficult to build a secret passage in his own place.

"Go in and have a look."

Someone took the torch, Lin Feng walked in the front, as he entered, the space inside became larger and larger, there was a hole under the Heaven and Earth Alliance, there were grooves for placing torches on both sides, and there were torches that had not yet been exhausted, the distance between each position was almost the same, it should be carefully designed, Lin Feng held the torch one by one, and the space inside gradually lit up.

"Good guy, what treasure is Long Tian hiding here, he can make a fortune now." Tang Niu laughed, born as a thief, extremely sensitive to this environment, once robbed the dark room, it is generally a valuable thing to hide in this kind of place, otherwise it is not worth such a big effort, it is conceivable that such a secret passage alone already requires a lot of manpower, and it is necessary to carefully set up organs.

There is a big black thing in the middle of the stone cave, all the way up, and a hole is opened in the lower position, and an iron trough is placed under the opening, and there are several tables on the side, with these things, from ironmaking to building weapons can be completely realized, and those weapons hidden in the side yard should be completed here.

After checking it carefully, they couldn't find the location where gunpowder and firearms were made, so everyone had to go back the same way, Lin Feng secretly told him to take care of those stones and sulfur, if anyone asked, he said that it had been destroyed, otherwise it would bring trouble, Wu Tianxiong nodded again and again, and he trusted Lin Feng very much after experiencing this turmoil.

The wine and food were put on the table, everyone was drinking and chatting, Lin Feng got up, "Everyone, Lin Feng has been out for a long time, it's time to go back, this cup is for all heroes." ”

"Lord Lin, the door of the Hero League is always open for you."

"Yes, I'll be back and see us brothers when I'm free."

"Okay,."
