Because the black gunpowder was completely developed, Chen Xu no longer had any interest in making clay pot grenades.

This kind of earth grenade is not very useful in the primitive battles of the Qin Dynasty, and the clay pot is fragile and not far away. Grenades are mainly used to attack the enemy's defending positions. However, for primitive tribes like the Huns, which rode on horses like the wind, it was better to use bows and arrows to get it. It is more likely to throw grenades on the battlefield to scare their war horses. Even if they were not scared, it would be bad to blow flowers and plants!

What's more, the Qin Dynasty now has new equipment, and can chase and kill on the battlefield. The advantage of the Hun horse speed is quickly lowered the gap.

Therefore, what Chen Xu wanted most was to make real muskets and cannons, but now the gunpowder is seriously insufficient, so the cannons are gone, and the number of gunpowder with dozens of hundred and eight kilograms is gone, so he naturally took his attention to the earth gun first.

After spending most of the day, Chen Xu hid in the huge laboratory of the Academy of Sciences, based on the style of earth guns he had seen when he was a child, and then based on some online pictures in memory and plots in TV movies, he drew a rifle-style earth gun.

In order to increase the shooting distance, the barrel of the gun naturally needs to be designed very long, so that enough kinetic energy can be generated in the unsealed gun chamber to push the projectile to fly far enough. Therefore, the barrel designed by Chen Xu is 1.2 meters long, plus components such as the butt stock, the length of the entire musket exceeds 1.5 meters.

The earth guns in later generations were all duck-billed hammers, and fire-induced fire was also a special fire bubble, commonly known as bottom fire.

Many friends born in the 2000s have never seen fire bubbles, but in the 1980s and 1990s, they were children's toys, which were stacked together with two layers of paper, like plastic bubble packaging bags, and were densely packed with small bubbles on them, containing a quantitative flammable gunpowder. Tear off a fire bubble and place it in the fire-induced position of the earth gun. Then, the moment the trigger was pulled down, the hammer hit the fire bubble heavily, and the gunpowder in the fire bubble would burn, and Mars splashed into the gun chamber through the fire hole to ignite the gunpowder, and the projectile would be fired.

The gunpowder of the fire bubble requires flammable and explosive properties to be very sharp. It is similar to the match head. It can be ignited with a slight friction. Its stability is much worse than gunpowder. It is estimated that it can be successful by mixing saltpeter and sulfur with an increased dose. Because even if two iron blocks hit quickly, Mars can be produced. As long as the instantaneous temperature is high enough, it can be ignited. Therefore, these are not what Chen Xu must consider immediately. What we need to consider now is to verify the power of the unearthed gun first.

Moreover, even if the fire bubbles cannot be made, it can basically be replaced by flint excitation. The world began to prevail in the late Ming Dynasty. The West first invented it. China began to appear in the Ming Dynasty. Therefore, the Ming Dynasty also had a powerful firepower that was not inferior to Western civilization. However, the Qing army suffered enough firearms and artillery in the battle with the Ming army. After entering the pass, the Qing army decided to use the bow and horse technology they were best at. Even gunpowder could not be produced by the people. Therefore, over the past two hundred years, Western firearms developed rapidly, and various strong ships, powerful cannons and even machine guns began to appear. The only major powers in the world, our Qing Dynasty was still riding horses and shooting archery. The Battle of Bali Bridge was a terrifying joke in the history of world wars. The Qing army attacked the 8,000 British and French coalition forces and killed five opponents at the cost of more than half of the casualties... Five people... Five people...

Therefore, judging from the victory and defeat data of the battlefield, hot weapons driven by gunpowder are the endorsements of cold weapons. Since the Qing Dynasty, flintlock muskets and artillery have become the main force of the battlefield. The era of cold weapons has never returned. The Battle of Baliqiao has completely awakened the Qing rulers who were closed to the country and decided to start developing firearms. However, the Qing Empire has become corrupted to the bones, with only an imperial standpoint, without the soul of the empire. Under the attack of the Eight-Nation Alliance, the skins are full of holes, and soon there is no underwear.

Compared with the later muskets, the flintlock method is much simpler. It is a piece of flint fixed on a duck-billed hammer. After it is activated, the flint hits the gunpowder nest, and ordinary gunpowder can also be ignited.

But at the moment, these are not the key points. The key points are the method of excitation. No spring or any automatic excitation device is a fart. Therefore, the most important thing now is to make a very high-strength spring first.

But you have to make a qualified spring...

Chen Xu's teeth began to hurt again.

So he completely abandoned the excitation device that he had worked hard to design for a long time and changed it to a coercine.

The mezzanine is too simple. It is a copper or iron pipe with a small hole at the end. First insert a piece of fire lead, and then fill the gunpowder and projectiles from the muzzle. The principle is similar to that of a clay pot grenade.

This is much simpler. Chen Xu looked at the modified drawings and actually added a wooden handle to a pipe.

He took a few drawings and went out, called the groom and the guard out of the city.

Although there is no spring at the moment, there is already carbon steel. Gongshusheng and Ma Rod can refine a furnace of high-carbon steel to pull out fine steel wire to make springs. After all, if it is really applied to the battlefield, rubbish like a comb, gun is not good. It is similar to a fire stick when it encounters heavy storms and snow.

I haven't been to the factory for almost half a month, and now the factory has become much more organized.

Since the last fire broke out, the emperor sent two hundred imperial guards to guard the factory. Not only inside the factory, but also on horseback patrols outside, there were imperial guards riding horses. No one was allowed to approach the factory wall. An arrow tower was built on the wall, and there was a watchtower inside the factory area, and the gate was renovated. The soldiers stationed in the garrison checked all the personnel, managers, supervisors, craftsmen, and helpers who were in and out of the factory. All the waist cards without the factory were arrested and interrogated.

However, Chen Xu was not in the inspection area. The carriage was still a mile away from the gate. Patrol soldiers came up. Then someone came to the factory to notify us. Soon, Ying Bu, the head of the factory's security department, rode a new type of saddle stirrup, wearing a black armored waist and a saber, with a leather forehead stud on his head. He looked heroic in military uniform. His look was completely different from the past, and he had a bit of energy.

"See the Marquis!" Ying Bu dismounted his horse and bowed respectfully.

"No gifts, what's the situation in the factory recently?" Chen Xu sat in the carriage and smiled and nodded.

"Go back to the Marquis, everything is fine!" Ying Bu said to the carriage after getting on the horse.

"Well, don't be careless and slack on weekdays. New pawn equipment is now a secret thing, so don't leave it!" Chen Xu reminded.

"Don't worry, Marquis, the drawings of weapons and equipment are now stored in a special secret room, and they are guarded by the imperial guards for twelve hours. All craftsmen and supervisors cannot leave the factory easily and will never leave the factory!" Ying Bu said quickly.

"That's good!"

While walking, Chen Xu asked in detail about the recent situation of the factory. After entering the factory gate, he saw two earth and stone walls nearly ten meters high built on the open space, and there were huge scaffoldings nearly twenty meters high on both sides. Hundreds of work slaves and helpers were sawing wood under the surveillance of military soldiers. There were dozens of work slaves on the scaffolding lifting wood and wooden boards with thick ropes under the command of craftsmen. The sound of trumpets and scolding sounds came one after another, and the noisy scene looked very hot.

"The Marquis is here!" Hu Kuan ran over to salute with a stack of drawings panting.

"How about it, are there any difficulties in building a water truck model?" Chen Xu got off the carriage and asked at half a huge wooden wheel that had a bit of the prototype of the water truck.

"The spindle and the movable ring have been installed successfully, but because it is one-to-one, the project volume is very large, and it will probably take half a month to complete it. As for the supporting transmission device, it will take at least one month to complete, and it may be spring to begin at that time." Hu Kuan said a little uneasy.

"Do it slowly. This is a process of accumulating experience. Anyway, even craftsmen who are proficient in water conservancy construction have not been found yet, let alone there is no hurry to use it!" Chen Xu patted Hu Kuan on his shoulder to comfort him.

"Mr. Marquis is not in a hurry, but I am very anxious. Kuan is very eager to see if the power of this water truck is as convenient and labor-saving as Marquis said!" Hu Kuan shook his head, and then continued with a little hesitation, "It is so time-consuming and labor-intensive to build in a flat and spacious place. At that time, it may be more difficult to build on the river bank. It is estimated that the water truck will be successfully installed for several months."

"It is certain that the water truck saves effort, but your lifting method is wrong, so everything will be so time-consuming and labor-intensive." Chen Xu said with a smile.

"It is like this when building houses and city walls. It depends entirely on manpower to lift them. How can we say that we can save effort easily?" Hu Kuan shook his head and smiled bitterly.

"No, your method is too crude, and it is easy to miss it. Once the wood falls down, it will cause casualties. If you use the tower and pulley set, it will be much safer and easier!" Chen Xu said with a smile.

"What are the hanging towers and pulley sets?" Hu Kuan asked excitedly when he heard two new terms, his eyes became shiny.

"Come on, I'll draw it for you. It's very simple and practical!" Chen Xu picked up a wooden stick and swept the sand on the ground out of a flat open space with his feet, and then casually drew a tower like a hanging tower.

"See, this is a hanging tower. The tower body can be built with thick wood, just like a scaffolding, with a long wood on top as the tower arm..."

"A fulcrum that can rotate left and right up and down is installed in the middle. There are ropes and iron hooks at both ends of the tower arm, which is actually similar to the principle of the scale, but the rope on the strut is replaced with a fulcrum..."

"The iron hook at the back end of the tower arm is used to hang heavy objects, just like a weight. The heavier the weight, the larger the heavy object raised at the other end of the tower arm. The helper can pull the rope on the ground and swing the tower arm. Naturally, he can hang the heavy objects to the position where they need to be placed. Just one person needs to stand on the top of the tower to shake the flag and command...
