'boom!'

"Your Majesty, it exploded again!" After a loud bang, a group of people jumped out of a trench and ran to the explosion point. Chen Dun shouted at the little emperor.

"Stop yelling, I heard it. You are afraid of eating dirt. Now you will be deaf in your ears!" Zhao Bing, "Push," spit out the sand in his mouth and shouted in Chen Dun's ears.

"Your Majesty, stop trying, it's too dangerous!" Chen Dun rubbed his ears and kicked several big explosive barrels that were tilted to the side.

"What's going on?" Zhao Bing squatted down and checked the iron bucket dragged by the guards just now. He has been thinking about how to be slutty all day long, making his head swell and annoyed. But he is a 'patient' and cannot go out to relax casually. Thinking about how he really regards being an emperor as his main business now, and has not entered the studio since the war started.

Working in the old business is definitely a good way to reduce pressure, and immersing himself in it will disappear in a moment. In the Battle of Guarding the Tomb, Zhao Bing discovered that although the Baizi Gun and the Thunder Cannon are powerful, their firing rate is low, and in order to maintain firepower, they can only make up for it by quantity. In the offensive, both weapons are limited to the slow loading speed and it is difficult to keep up with the speed of the offensive troops. At that time, he thought whether he could produce another weapon to solve this problem, especially in the plains against cavalry.

The first thing that Zhao Bing thought of was the "conscienceless cannon" made by our army in his previous life. This thing is a simple structure, with only a gasoline barrel as an explosive pack launcher. After filling it with the launching medicine, the explosive pack tied into a disc-shaped one was put in it, and then igniting the launching medicine, and then the ten kilograms of explosive pack can be shot to a distance of about 200 meters.

The caliber is absolutely amazing - the thicker the barrel is, the larger the caliber. The strong explosive impact of the huge explosive pack has strong lethality to unprotected cluster soldiers. Some simple fortifications will also be destroyed. As long as it falls within a radius of five meters, all living things or fortifications will be difficult to escape. However, there should be no enough blow to armored targets, but there are no tanks in this era, and armor cannot stop its huge lethality.

Zhao Bing is not a conscience-free cannon because it is simple to manufacture, has great lethality, and has varied functions. Everyone thinks it was invented by our army, but in fact it had appeared as early as World War I. This weapon was originally designed to project incendiary bombs, and occasionally it was used to throw cluster grenades as a supplement to ground artillery fire.

In the Battle of Aras, Livens' projectile was used on a large scale in chemical warfare for the first time. The British army threw 2,400 poison gas bombs into the German position 300 meters away in one volley. These projectiles filled with poison gas exploded and released nearly 20 tons of phosgene, causing heavy casualties from the German army. After that, Livens' projectile rarely fired incendiary bombs, becoming a special poison gas bomb bomb projectile.

Later, our army innovated in order to solve the shortage of artillery and poor attack capabilities, and made conscientious cannons based on their principles. Since then, we have continuously improved our technology to exert the maximum power of flying thunder. In order to deal with the Kuomintang army's tanks, armored vehicles, field fortifications and dense formations, they used the projectile barrel to modify the earth-made flamethrower, used the projectile barrel to eject dozens of kilograms of stones, and flew cluster grenades, etc., with more and more patterns and greater power...

"Your Majesty, is the iron barrel material not suitable?" Chen Dun also squatted down and knocked on the iron barrel path with his hands.

"No!" Zhao Bing shook his head and said.

He knew that the one who made the unconscience-free cannons in his previous life was to use discarded gasoline barrels. Even the Liwens projectile cannon was only transformed and welded from thin iron barrels. Wuhu was one of the earliest iron smelting and manufacturing bases in my country, and not only had rich iron ore resources, but also had superior transportation locations. As early as the Spring and Autumn Period and the Warring States Period, iron smelting and casting began here. The legend of Gan Jiang Moye making swords in Chizhushan has been circulated among the people, and the Wuhu area used the steel filling method to smelter steel in the Song Dynasty.

Simply put, this method uses the chemical composition of the steel carbon content between pig iron and cracked iron, eutectic pig iron and cracked iron, and pours the melted pig iron into cast on the cracked iron to make the cracked iron carbon into steel, and the cast iron removes excess carbon and impurities into steel. At this moment, a mature process used in Qiongzhou has been introduced. Zhao Bing feels that even if it is not as good as the quality in his previous life, it should not be easily exploded.

Looking at the cracked iron barrels around him, Zhao Bing was also a little scared. After he thought about it a few days ago, he asked Wuhu Metropolitan Hospital to build a three-foot-long iron barrel with a diameter of one foot for himself, and equipped it with a wooden bracket. He came to this deserted beach to test the cannon. After erecting the iron barrel, he first placed a four-pound launching medicine bag at the bottom and put it on the shelf, and then placed a twenty-pound gunpowder bag tied into a round cake on the shelf. After installing the fuse, the launching medicine was ignited.

Zhao Bing originally wanted everyone to see his "new invention", but with a loud bang, the cannon almost destroyed and died. When the launching medicine was ignited, the cannon body turned over under the push of the detonating gas, and the flames instantly ignited the explosive pack again. The iron barrel was blown up several feet high, and the cannon stand was broken into pieces and reduced to firewood. If he hadn't always been cautious, he dug up the bunker in advance, and they were blown away together.

The lottery was not out, but it was covered in dust. Zhao Bing was not discouraged and then conducted an experiment. At first, he thought the dosage was not suitable and the stent was not strong. The next day, he adjusted the dosage and made a secondary iron cannon stand, but the result remained unchanged. In a fit of anger, he asked the Duzuo Hospital to do 7 or 8 iron barrels, constantly adjusting the dosage for experiments. Of course, the fuze was getting longer and longer, but the barrel cracked was only different. In the end, he didn't dare to fill the medicine bag, worried that he would fly around and lose his bones to the blown bones.

"Your Majesty, let the craftsmen make a few thick iron barrels and try again tomorrow!" Chen Dun was a little scared. The power of the explosion of dozens of kilograms of gunpowder should not be underestimated. It's nothing to blow up a few barrels. If you hurt Your Majesty himself, it would be a hundred deaths. Mo Shu kept persuading.

"I'm afraid it's not okay if I'm thicker!" Zhao Bing touched his chin and shook his head.

"Your Majesty, then go back and think about it, and then try again..." Chen Dun persuaded again without giving up.

"Damn it, I was deceived by them again!" Zhao Bing seemed to have not heard Chen Dun's nagging, and after thinking about it for a while, he suddenly cursed.

"Who dares to deceive Your Majesty is the crime of deceiving the king. I will arrest him immediately!" Chen Dun said after hearing this.

"Catch it, you don't know them, so dig a hole!" Zhao Bing said angrily. He just thought that the strength of the gasoline barrel was very low, and the launching medicine was much more powerful than the black gunpowder he used now, but there was no rupture. It was obviously not a problem with the strength of the gun body, but the wrong launch method, which led to failure.

Zhao Bing also accidentally remembered that he had seen an old photo, where the unconscience-free cannon was buried in the ground. This made him realize that the strength of the projectile barrel is very low, and it is not the projectile barrel that bears the chamber pressure during launch, but the soil outside the chamber. You must bury the projectile barrel in the soil, and the soil outside the chamber and behind the chamber must be compacted. In this way, the huge chamber pressure can be transmitted to the soil layer through the projectile barrel. Only when the soil layer bears the chamber pressure, the ejector will work, otherwise there will be a chamber explosion accident.

Then with the victory of the war, the weapons and equipment were constantly updated, and weapons with complex operations and high dangers such as the cannon were eliminated, and the use of this weapon was gradually forgotten. The directors and directors of the film and television dramas took it for granted and placed the ejector on the ground. The scene of this interpretation was not only a lack of common sense, but also misled the young people like Zhao Bing, thinking that it was really used in this way.

"Your Majesty, the pit has been dug!" The effort was not great, and a three-foot-square-meter earth pit had been dug, Chen Dun reported.

"Okay!" Zhao Bing looked at it and nodded. Then he jumped out of the pit and put the last iron bucket in at a forty-five degrees angle. Then fill the void with soil and compact it. Finally, leave a place to install the fuse, add another layer of soil and tamp it until it is three inches away from the mouth of the barrel. After fixing the iron bucket, someone weighed a pound of gunpowder and wrapped it into a medicine bag and placed it on a wooden base. After connecting the leads, he loaded the sealed partition and a ten-pound soil bag in turn.

"Immediate!" After Zhao Bing and others retreated into the trench, they shook the red flag and made people ignite the fuse.

‘Boom!’ With an explosion, Zhao Bing saw a firework spewing out with smoke from gunpowder, and the earth buns and sealing plates flew out from the mouth of the barrel. Then he slowly flew higher and higher. After rising to the high point, he fell rapidly, and a stream of smoke rose on the ground. He estimated that it was about a hundred steps.

"Success!" After the landbag landed, Zhao Bing quickly ran to the ejector, and saw that the iron barrel was intact, and couldn't help but shout excitedly.

"This dog has to bury it alive before working hard!" After struggling for several days, Chen Dun couldn't help but laugh and scolded.

"Your Majesty, the landblock was shot for 10 steps!" The accompanying guard also ran back to report after finishing the measurement.

"Okay, let's just install live ammunition this time!" Zhao Bing said after seeing the pickup of the trash buns. Several people nodded vigorously, but they could be considered to have worked hard. Success or not fell secondly. This fear made people really unable to bear it.

After cleaning the barrel, two kilograms of launching medicine bags were added as Zhao Bing's request. He had just seen the hemp ropes tied to the earthblocks he picked up were burned by burning gunpowder, so he would switch to a leather strip, and the medicine bags were also increased to fifteen kilograms. After filling them in the previous order, he estimated the time when the medicine bags were flying just now, intercepted the fuses and installed them, and ignited them again.

Accompanied by the roar, the gunpowder pack flew out, and this time it flew higher and farther, and it was delayed for a moment before it exploded. Although they were a distance away, they could still feel a strong wind blowing on the face, and the stones and soil blocks then crackled down. When the smoke of gunpowder dissipated, they walked over and saw a pit three feet deep on the ground, and the artemisia and shrubs within three feet of radius were all swept away by shock waves.

"Your Majesty, if this falls into the crowd, the people around you will be shocked to death if they are not killed by the bomb!" Chen Dun has been on the battlefield and has seen the appearance of a rocket after it explodes. This is obviously even more powerful and can definitely be called a killing weapon.

"Oh, it seems to be successful, but you still have to keep testing to find out the rules. But this thing is okay for persistence and siege, but it won't work if it can be used for attack!" Zhao Bing sighed.

After all, this explosive ejection barrel has some similarities with ancient heavy mortars. It is used in a large elevation angle. Although it has a relatively close range, it is amazingly powerful. It is good to use it against enemy fortresses, foul corners and siege cities, and it is also good to carry out saturation bombing of the attacking enemy troops. However, there are also difficulties in moving and the disadvantages of long preparation time, making it difficult to keep up with the attack.

However, Zhao Bing soon thought of another little brother of the mortar, the mortar. If it were counted in a few decades, its original prototype would appear. At that time, the Spanish army besieged the city of Alihkilas, which was occupied by the Arabs. The Arabs laid a short corner tube on the battlements, and the mouth of the tube was raised high towards the outside of the city. A packet of black gunpowder was placed from the mouth of the tube, and an iron ball was placed, which ignited the medicine and then shot at the Spanish soldiers outside the city. This primitive cannon, known as "Modefa", can be said to be the prototype of modern mortars.

But the world's first real mortar was born hundreds of years later. During the Russo-Japanese War, the inventor was a Russian artillery captain. At that time, Tsar, Russia and Japan fought fiercely to compete for China's Lushunkou. The Russian army occupied the Lushunkou fortress. The Japanese army dug trenches and approached the Russian positions. Generally, artillery and machine guns were difficult to kill the Japanese army. So he tried to modify an old small-caliber naval mortar on a gun stand with wheels and fired a long-tail shell at a large elevation angle. As a result, it effectively killed the Japanese army in the trenches and repelled the Japanese attack.

Since its inception, the mortar has been an effective suppression weapon to support and accompany infantry combat. It is easy to operate, with a bent trajectory, and can approach the target to shoot, and there are almost no shooting dead spots. In addition, after the shell is loaded from the muzzle, it relies on its own mass to force the firing to make the shells fire. In addition, it has good killing effect on unprotected targets and is suitable for shooting targets behind the shelter and targets on the back slope. In addition, the mortar is a small light artillery, which is flexible and light when used, and is suitable for concealing activities with infantry.
