Country and Beauty

The rocket that was flying through the air exploded with a loud rumble. Smoke filled the air and the fragments of the rocket exploded at a speed that was hard to see with the naked eye. Based on Xie Fei's understanding of firearms, this rocket launcher's killing radius was around 10 metres. If it wasn't for the lack of time, it could be said that the rocket launcher's experiment would have been a success.

Xie Fei had yet to speak, but the group of ass-kissers beside him did not understand what he meant and instead flattered him loudly, "Alright, that's great, it's simply more powerful than the Fu Lang Artillery!"

Xie Fei was secretly annoyed in his heart, "Big brother, don't pretend to be knowledgeable if you don't understand it. This is a primitive Flowering Bullet, is it the same as a Solid Bullet? "

"We, the Emperor, are wise. With such a sharp weapon in our hands, we, the Great Qin King, will be like tigers that have added wings!"

"Professor Dai is really intelligent. I didn't expect that a sharp weapon would appear the moment I took over the Institute. This means that Lord Dai is knowledgeable and that His Majesty is knowledgeable!"

Facing the praise of his colleagues, Dai Shengquan had no trace of joy on his face. Although these useless colleagues couldn't understand that the rocket launcher had failed, he knew that Xie Fei was definitely an expert in the field of firearms research. He didn't dare to make a move in front of Xie Fei and fearfully said, "Your Majesty, this subject will be sentenced to death!"

Xie Fei worriedly rushed towards Dai Sheng: "Failure is the mother of success, a accidental failure doesn't mean anything. The important thing is to find out the reason for the failure. This can be improved so that research can go further and further. His achievements are getting higher and higher! "

At this time, the technicians who had gone to check on the explosion reported back, "Your Majesty, your subject has investigated thoroughly. Your subject has calculated that the explosion would occur because the fuse was burning too fast. Your subject has calculated that if the fuse had grown one third longer, it would have been able to explode on the ground!"

"Then why don't you go get it? Don't you have three rockets?" Dai Sheng asked anxiously. "Hurry up and test it out!"

The technician nodded his head, and then asked the craftsman to place the growing rocket on the bed crossbow. Then, he pulled the string, and as he ignited the rocket fuse, he moved the crossbow's mechanism, causing a "Peng" sound, and the rocket flew into the air. This time, there was no accident, the rocket flew over eight hundred steps, accurately hitting the target that was half a man tall.

The visiting ministers were also cheering. Dai Shengquan excitedly picked up the technician who had designed the rocket launcher and patted his shoulder with his big hands. "Good boy! You're the real one! I'm the real one! I'm the real one!"

The technician wasn't as happy as Dai Shengquan. He said directly to his boss with a cold expression, "Is this enough?"

Dai Shengquan nodded.

The technician shook his head and said, "Actually, this experiment still failed. Didn't you see it? In fact, the rocket exploded two breaths after hitting the target. More accurately, the experiment also failed! "

Dai Sheng laughed. "Isn't that simple? Can't you just cut the fuse a little shorter?"

"If the enemy is 800 steps away, then the rocket will explode in the air! "What's the use?" The technician said solemnly.

Dai Shengquan secretly sized up Xie Fei and found that he was excitedly looking at the scene of the explosion. He whispered, "Do you have any way to solve this problem?"

"Yes, there is. Like His Majesty mentioned, triggering a fuse, or triggering gunpowder with a flintlock device like a musket, is fine. But I still don't know how exactly to do it!" The technician frowned again and said, "If I can make the trigger fuse required by His Majesty, not only can I make rockets, I can also make more powerful cannons!"

Dai Shengquan said, "For now, we can only try our best to lengthen the fuse as long as possible. Even if the target cannot explode, it's better than exploding in the air!"

"Pah!"

"Who dares to hit me?" Dai Shengquan jumped up as if he had been stepped on. He was one of the ministers in charge of the 23 departments in Great Qin, a substitute cabinet. He could be considered a powerful minister in the Great Qin, yet he had hit his head in front of so many people. Let Dai Shengquan be very angry!

However, when Dai Shengquan turned around, his anger and unhappiness had all disappeared. He smiled as he knelt on the ground and said, "Thank you for your beatings, Your Majesty!"

said resentfully, "It's fine to use this Rocket shell to attack a city and hit a fixed target, but if it's used on an active enemy, then it's only effective if it hits the enemy, otherwise, it would be a waste when he lands on the ground. Even though our Rocket is powerful, we can't control the time it takes to explode. Once or twice the enemy has suffered a setback, they will learn to be smart, and when they see our Rocket fall to the ground, they will quickly dodge it regardless of whether it is a shell or not. When it explodes, the effect will be extremely limited. And do you know how much money it costs to make rockets? If you use fifteen silver taels per rocket as a rock to smash the enemy, even if our country's treasury is filled up, it won't be enough for you to lose.

Facing the many technicians from the Polytechnic Academy, Xie Fei could not really blame Dai Shengquan. And then he prepared to leave. "Your Majesty, we can continue to study the rocket launchers. This line of thought should be correct, this kind of weapon is suitable for our Qin State's army to use on a large scale!"

Xie Fei said: "Wrong, this kind of weapon is suitable for us, but our money is limited, even if it means building a nation as a nation, benefiting the nation and its citizens, we will still spare no effort in building up three schools. To cultivate more all-round talents for the Qin State, we have to develop our economy, to strengthen our country and its rich people, our money is still too little. "Right now, ordinary people can only eat meat a few times a year. This Emperor has really neglected his duty!"

The surrounding officials were once again filled with a wave of sighs. For an ordinary commoner of an emperor to not starve to death and burn incense on such a large scale, how could they expect them to eat meat? But no one dared to directly say that to Xie Fei.

"Then, Your Majesty, what kind of weapon do you think is the most suitable for our Qin State's army?" Dai Shengquan asked seriously.

"It's light, economic and powerful." Xie Fei blurted out an answer: "Light, it means light and fast, it can be used to attack and also be used in the field. The enemies of the northern side of my Accompanying nation are mainly the nomadic peoples s, their greatest strength is that they possess cavalry, while the enemies of the southern side are the evil mountains of the forest. In this way, we can use our weapons to the maximum extent possible to restrain the enemy's cavalry, allowing us to move quickly in the evil water of the poor. Furthermore, if the enemy can't enter the forest or the valley, and cannot move quickly, then the enemy cannot be killed! "

"Economic, I hope that this kind of weapon can be made at a low cost, but also at a convenient and quick rate. At the same time, the consumption of gunpowder is also at a minimum, so the cost of using this weapon on explosives is better." Our Great Qin has a million regular troops, so even if a million troops, we still won't be able to fully handle the current war, but we need even more troops. Even if we each have a gun and cannon, the number will be in the millions, and with these types of rockets, even if we only have 100,000 of them, it would cost us one million and a half hundred thousand Qin coins. This is enough for two million families to spend for one year. Xie Fei continued, "In the future, we will have to pay attention to the expenses of the research institute, otherwise, we will not allow any equipment that is not economical or practical to be equipped!"

"In addition, you don't need me to say it clearly. You should understand why I haven't had anyone to ask you to create a cannon in the past three years." No matter if it was the Buddhist cannon or the Red Barbarian Cannon, this type of cannon used up a lot of steel. Moreover, it would be scrapped if it did not fire as many cannons as it wanted. In the future, the Polytechnic Academy will focus on the more powerful gunpowder. The more powerful the cannon, the more accurate the shot. "

Xie Fei concluded, "The purpose of these firearms, is to throw gunpowder at the enemy's head and explode. The more powerful the firearm, the more gunpowder the enemy will throw at their heads and explode. "The best firearms, should be able to use the least cost, the least amount of propellant consumption, and the fastest speed to throw most of the explosives at the enemy's head and explode."

"This is a horse running and not wanting the horse to graze! Is there such a good thing in the world? " Dai Shengquan muttered in his heart.

The technician who invented the rocket boldly said, "Your Majesty, although I still have a lot of problems with the rocket, its speed is relatively fast. Although its accuracy was not high, as long as it could solve the problem of triggering explosions, it could be mass-produced. This could also save the cost, using rockets from the front, replacing ambiguity with precision, and replacing materialization with quantification. "It's just that it's not powerful enough."

Xie Fei said: "This is because the power of the gunpowder we are using is not strong enough, the gunpowder we are currently using is mainly black gunpowder, if we were to use nitrocellulose gunpowder, the power would be even stronger!"

The technician said, "Today's rockets are all improvised by me. There is still room for improvement in the tail, balance wing and nozzle. Given a little time, I can refine the rocket to make it more accurate and more convenient to manufacture and carry. And I'm going to use the barrel instead of the crossbow to push the rocket. "

"What?" Xie Fei was dumbstruck, "Your cannons replace the crossbow?"

"That's right!" The technician said, "The cannon's principle is to use the explosive power of gunpowder to throw the warhead. I think the rocket can also do it, but this type of rocket is lighter than the warhead and easier to shoot. As long as you change the cannon slightly, it will be easy to cast it. Mold made out of mud requires extremely high drying, otherwise, once there is water left inside, it would produce steam the moment it came into contact with the iron, causing the barrel to have bubbles in it and making it very easy to blast the barrel. Therefore, the mold needs to be dried for a month, and once wet, it needs to be heated for two to three months before it can be used. What's more troublesome is that a set of molds can only be used once, and once used, it will become useless. The speed and efficiency of the cannon can be imagined. "

Xie Fei also knew that the current technology used to forge cannons was far behind, but he had no choice. Although he knew that the future generations of advanced technology and techniques were advanced, he still did not know the specific requirements, and with his current abilities, it was impossible for him to forge cannons as precise as the future generations of cannons.

The technician continued, "The cannon barrel can be made out of pig iron!"

The moment the words left his mouth, everyone was shocked.

"Are you crazy? Isn't it easy to connect pig iron and molten steel together? "How do we separate?"

"Whoever comes up with this idea is either a fool or a lunatic!"

In the face of so much slander, the technician continued, without discouragement, "Pig iron, of course, cannot be used directly as a mold. First, it is cast into a hollow mold, with two iron internal molds that can be drained out of the water, and then two layers of slurry are applied to the interior of the outer mould. The first layer is made of fine rice husk ash and fine sand; the second is made of very fine kiln coal. Then, the two cladding, with iron hoops tight, hot, joint after segment, finally casting metal molten casting gun.

"The biggest advantage of this method is that its dimensions are the same, the mold can be used repeatedly without needing to be dried out for a long time, and the efficiency of the method will naturally be greatly improved. Moreover, it will not produce a bubble cell, which can extend the life of the cannon, reduce the rate of waste products, and is most conducive to large-scale casting."

This kind of cold water cooling iron method used an inner mold to inject cold water into the inner shell of the cannon, allowing it to quickly cool down. Under the pressure of thermal expansion and contraction, the iron density of the barrel concentrated onto the outer shell, the inner shell would naturally be harder than the outer layer, and when the shell was fired, the huge pressure would also be distributed to the hardest inner shell, which could increase the cannon's lifespan to the maximum. At the same time, it could also further reduce the rate of waste products and the cost of casting the cannon. Basically speaking, this was undoubtedly a revolutionary development in the artillery industry.

If this method was used, it was possible to create cannons, muskets, and mortars.

Only then did Xie Fei ask a question that sounded like an idiot: "What's your name?"

The technician said, "This one. His surname was Yan Hu (According to the relevant information, the Dragon Slaying Halberd in Ran Min's hands was forged by the blacksmith surnamed Yan).

Xie Fei said: Oh, my beloved one, I shall leave this matter to you, you better not disappoint us! Thus, the Institute of Science and Technology has earmarked a portion of its funds for artillery development and rocket research! " Forget it, the funding for the Polytechnic Academy won't move. We will allocate another sum of money from the Finance Department for the research. We will give you 100,000 Qin coins, not 500,000 yuan. My beloved one, do not disappoint us.

Yan Hu did not disappoint Xie Fei, but Beigong Chun was a little uncertain. Although they said that they were going to make use of Bai Xiang Mountain, where Beigong Chun had raised the morale of the National Guard, when he arrived at DingXiang, he felt even more uneasy.

It was not that Beigong Chun had never fought a vicious battle before, it was just that he had not fought a risky battle with fewer victories, just that now was not like in the past. In the past, even if Qin Army won a few battles, the enemies that she faced were crude weapons and poor training of soldiers. They were the Xianbei member and the Capricorn who had obtained a large amount of equipment from the Xiangping and Wang Ping. Amongst the Five Hu, the Xianbei member and the Capricorn had the strongest fighting strength, but the soldiers in Beigong Chun's hands were all new recruits who had not been baptized in the battlefield. Furthermore, they did not have the advantage in weapons!

However, it was a good thing that the Xiangping and Wang Ping City did not have any cannons in their storage. Otherwise, they would have no chance of winning. Furthermore, Beigong Chun still had a bit of time to hone his skills. As he trained as he marched, he was already familiar with the way to train his troops. Under this dual stimulation, even the weakest soldier could be trained to be a hot-blooded man. This set of methods was Xie Fei's military training treasure. It had proved to be effective, and there was nothing to worry about.

After exiting DingXiang, the Qin State would have no other cities to supply northwards. Beigong Chun was a little worried, they were going to use the tactics of the future generations Mongols to go on an expedition, other than carrying everyone else who could eat dried meat and milk powder for two months, it would just be weapons and ammunition. Although the weight of the powdered milk and dried meat was much lighter than two months of food, but these weights, in addition to the full body equipment, were not what a normal person could bear. Helpless, Beigong Chun could only temporarily stay in DingXiang and carry out his final military training.

After Beigong Chun gave the training order, the chief of staff, Zhang Weizheng, hesitated for a moment and said carefully: "If the Great General tied a 5 jin sandbag to his leg, marching 70 to 80 Li per day, and training during camp, this is too strong, I'm afraid the other brothers will not be able to hold on."

"Then, let me ask you something. Would it be a problem if you tied this sandbag and trained in it?" Beigong Chun said with a stern expression.

Zhang Weizheng laughed out loud, and shook his head with confidence: "This is nothing, I once fought with His Majesty in the Western Regions, a small five kilograms sandbag. Not just me, I am confident that any officer of our National Guard s have this ability. "

"Hehe, he's not a human anymore. Everyone has their own shoulders and a head, no one is weaker than anyone else. If they can do it, everyone can do it, so this general ordered, from today onwards, everyone in National Guard, from top to bottom, will be tied up with five kilograms of sandbags, and they will be forced to eat and sleep everyday. Beigong Chun said with a stern expression.

"Understood!" Zhang Weizheng was just about to go down and tell Beigong Chun: "In addition, tie up all the war horses with sand bags, even the crossbow horses have to be tied up. I need to train everyone's stamina within half a month, and also tell the soldiers, who doesn't have the stamina to go. "Get the hell back home right now. Laozi would rather go onto the battlefield by myself than send a bunch of punches to their deaths!"
