Ma Jun is indeed a great scientist, inventor, and manufacturing expert. In the following month, Ma Jun led a large number of craftsmen under his command to study and experiment. They continued to summarize and correct, and finally created a seamless steel pipe that Lu Ning was very satisfied with after seeing it.

Researching seamless steel pipes does not mean that they can develop artillery. There are still many problems that need to be solved, especially the grinding of the inner diameter of seamless steel pipes is very troublesome and difficult. Moreover, the current conditions can only be completed with manpower, and there is no machinery to build. Of course, our craftsmen are indeed very outstanding talents. They just use their hands to make the steel pipes bright and smooth, with their accuracy as much as that of later mechanical finishing production. This is really difficult for them. They are really great and unimaginable.

Lu Ning also explained the production process, production process, difficulty in production and various solutions to Ma Jun and others. In fact, it is just a rough explanation. Could it be that Lu Ning can still produce artillery? He can only talk about the principles and what he saw and heard in later generations on the Internet, TV, and movies.

Of course, Lu Ning could not have created a powerful artillery in later generations, that is, the artillery that was set off on movies and TV. It is estimated that it is not as powerful as fireworks and firecrackers in later generations. It is probably not as powerful as there, and it is even more impossible to use a firing needle or something. After all, there is no high-explosion explosives yet, and they are all made black gunpowder. However, after the purity of nitrate and sulfur, its power has been greatly improved, so it is impossible to produce high-explosion yellow explosives. Under the current circumstances, under Lu Ning's rule, it is impossible to produce sulfuric acid, nitric acid, glycerin and other things, so it is impossible to produce high-explosion explosives.

As for the shells used for artillery, it is not a big problem. Since there is gunpowder, it is still a piece of cake to make a land cannon. The firing line is simpler, just wrap the gunpowder with twine. The range of the cannon will not be too far, and it is estimated that it will be as high as two or three kilometers. I will never dream of the dozens of kilometers and hundreds of kilometers of future generations, and the lethality will not be too high, and it will mainly play a more threatening role.

Everything is ready, and the simple and rough artillery was created by Ma Jun and the others. How powerful is it and whether it will work? As for whether it will explode, Lu Ning is not sure, and Ma Jun and the others don’t know. Anyway, everyone believes in Lu Ning, and everyone believes in Lu Ning’s words. After all, no one of Ma Jun and the others can imagine the power and function of artillery. This is a work of the century and a hot weapon. It is completely different from cold weapons. If it succeeds, it means that Lu Ning lets the Han people enter the age of hot weapons ahead of time. Its significance is conceivable, and it also means that the rise of the Han people is about to come.

Guo Jia, Tian Chou, Sima Lang, Zhang Ji and others heard that Ma Jun and others had developed a new weapon with infinite power. They also knew that Lu Ning would go to test artillery with Ma Jun and other great craftsmen today. The civil and military officials under Lu Ning also came to help. It was a polite word to say help. In fact, they wanted to feast their eyes and also wanted to know how powerful the new weapon was. How could Lu Ning stay in the Academy of Sciences all day long and not care about war and internal affairs. They knew at home that if it weren't for a powerful weapon, Lu Ning would never be so concerned. Just like when he first started to study gunpowder, Lu Ning was devoted to it. He ate, lived and worked with Ma Jun and other great craftsmen, and it was not finished until it was developed and put into use.

Lu Ning took his senior civil and military officials and the great craftsmen under Ma Jun who participated in the development of artillery to test the artillery. The artillery was led by a wheeled carriage and escorted by five thousand "Night Eyes" soldiers to more than 20 kilometers north of Jinyang. It was the training base of Lu Ning's army, with a radius of more than ten kilometers and a wall around it, so outsiders could not enter. The defense inside was tight, and they said that they could not even fly in.

Along the way, Guo Jia, who was beside Lu Ning, was originally a person who was very concerned about new things. When he saw something, he always asked the whole question until he knew it. Especially since he followed Lu Ning, the time traveler, he saw too many new things and new things in Lu Ning. This made Guo Jia feel mysterious about Lu Ning. He only knew that Lu Ning knew too many things, many of them were impossible to understand and imagine, and many of them were even incredible. He knew that Lu Ning was just a very ordinary college student in his later generations, and he had less than a year of work, and he was just an ordinary person. Of course, the era when Lu Ning grew up was an era of knowledge and information explosion. After all, he had two thousand years of knowledge accumulation than Guo Jia and the others, which was not something Guo Jia and the others could understand. Even if you were a genius, you were not as capable as an ordinary person in later generations.

Guo Jia looked excited and looked at the cannons pulled by the carriage, and was even more worried. Although he had passed the dark guy long ago, he could not imagine how powerful this thing was when he saw that there was not much attractive place outside. "Lord, is this cannon really useful? It's more useful than our army's catapult cart, and the crossbow bed?"

Lu Ning laughed loudly after hearing this, and glanced at Guo Jia and his subordinates next to him, and then said in a very confident language: "Fengxiao, don't worry, this cannon is definitely a cross-century creation. Ma Jun and others have developed artillery, which is of milestone significance. The emergence of artillery will mean that the form of war will have qualitative changes, the way of combat will have siege changes, and it will be much easier to capture cities and villages, and the casualties of soldiers will be reduced a lot, which will even affect the outcome of the battle."

Tian Chou next to him was even more excited after hearing this. If it was as true as the lord's words, it would be much easier to unify the world. Why would the princes still fight us? "Lord, is this black artillery Zhao useful? Our army's catapult cart, crossbow bed, and crossbow are extremely fierce. If it is really stronger than these weapons, it would be too terrifying. If this is used on the battlefield, the opponent will probably not have a chance to win in a row!"

After hearing this, Lu Ning smiled slightly and said casually: "Fengxiao, Zitai, the emergence of cannons means the arrival of the age of hot weapons, and cold weapons will gradually withdraw from the stage of history. This is an inevitable trend and no one can stop it. It also means that war is more cruel, killing is more unlimited, and more people will die. The success of cannons will not take long, and the emergence of rifles and machine guns will be soon. At that time, if you continue to use cold weapons to fight, you will have no chance of winning at all. You can only be someone else's hand and the life of being slaughtered."

Guo Jia was stunned when he heard this, why didn’t he understand at all? He was like listening to a book of heaven, and only knew that the impact was huge. What was it? "Lord, what is a cold weapon? What is the era of hot weapons? Why are we like idiots and unable to understand nothing?"

Lu Ning shook his head when he heard this. If you understand hot weapons, it would be amazing. These are weapons and equipment that only appeared thousands of years later. It is normal for you to understand them. If you understand them, it will be troublesome. "Cold weapons are the weapons and equipment such as swords, guns, swords in our hands. They are wars that fight close by through the physical strength of soldiers; and the emergence of hot weapons will change the way of war. Soldiers can destroy the enemy through the hot weapons and equipment in their hands. There is no need to let soldiers fight close by, and they can eliminate the enemy at a long distance. The two armies do not have to fight close by, but they can solve the battle at a long distance."

Tian Chou was stunned after hearing this and immediately said, "Lord, the catapult cart, crossbow bed, and crossbow used by our army can also destroy the enemy at a long distance? Are crossbow, crossbow bed, and catapult cart also a kind of hot weapon?"

After hearing this, Guo Jia nodded in agreement. How could a crossbow bed, catapult cart, and crossbow change the way of combat? Although these weapons and equipment are indeed very fierce, it is still impossible to say that it will change the outcome of the battle. "Lord, crossbow, crossbow bed, and catapult cart are indeed powerful, but it cannot be said to be a milestone leap! I still can't understand this. Although using these weapons and equipment has laid a good foundation for victory, it cannot be said to be omnipotent. As for avoiding close-fitting struggles, it is inevitable. After all, the opponent will still rush to close to kill, and at that time the soldiers' combat capabilities will play a key role."

After hearing this, Lu Ning couldn't laugh or cry. Why did this and that? How come the crossbow, crossbow bed, and catapult cart have become hot weapons? What do you say? "Fengxiao, Zitai, the hot weapons I mentioned are not crossbow bed, catapult cart, etc. The cannon is just one of them. It is a new weapon that uses heat energy to weapons and equipment to make the power of weapons and equipment stronger and more lethal. I can't tell you clearly, or you will know it when you see the power of cannons. Now I can't imagine it."
