conformed to Shen Kuo's wishes, and also took care of Su Song and Tang Xun's face, this is a win-win thing, and Lu Chengqi is still happy to do it. Shen Kuo heard this, and also said downhill along the donkey: "Your Majesty, look at the advantage of this rear-loading artillery, it's just that it is fast to load." These three cannons should be the artillery cast by Su Jianzheng and Tang Shilang with all their might, but they still can't solve the problem of air leakage. The minister was stupid and thought that such an idea was correct. It's just that Su Jianzheng and Tang Shilang are fascinated by the authorities, and they haven't thought of a stupid way yet. ”

Tang Xun and Su Song looked at each other, but did not stop Shen Kuo from talking. Lu Chengqi once said that it is not advisable to work behind closed doors on academic issues. If you want to make scientific and technological progress, it is impossible to rely on the strength of one person alone. At this time, it is time to brainstorm and find a solution together.

Lu Cheng inspired Shen Kuo to continue, and Shen Kuo was recognized by the little emperor, and he also said boldly: "The idea of installing a cannon door is a very good idea in the opinion of the minister. It's just that the problem of air leakage is too serious, so it was abandoned by the two of them. If the problem of air leakage is solved, won't it be another sharp artillery? ”

Lu Chengqi was interested, he always believed that the speed of fire of an artillery directly affected the direction of the battlefield. It is not difficult to bloom the bullet, Lu Chengqi has several plans in his mind, but the problem of rate of fire is not something he can solve, and he immediately said: "Shen Qing, continue to talk." ”

Shen Kuo nodded and said, "Your Majesty, the minister has a stupid method, which is also based on the ideas of Su Jianzheng and Tang Shilang......"

Seeing that Shen Kuo was like a singing woman who was still holding a pipa and half-covering her face, Lu Chengqi couldn't wait to reward him with a burst of chestnuts, and said in his heart: "You girl, just say what you think, is this hanging my appetite?" ”

Fortunately, Shen Kuo saw the unhappiness on his face, and hurriedly said, "...... Chancellor thinks. It would be nice if, like the Hongxiang rifle, this gun was equipped with a bullet. When firing a cannonball, simply load this bullet into the cannon door and ignite it to fire the cannon......"

Shen Kuo's words made everyone present confused and confused. Shen Kuo saw that none of them understood. He was so anxious that he pointed at a rear-loading gun and said: "Your Majesty, please see, just hollow out this place, and then make another bullet, which contains black, gunpowder and cannonballs, when you want to fire cannonballs, just load the bullets and ignite them......"

Lu Chengqi is a person who has more knowledge than them for nearly a thousand years, and after listening to Shen Kuo's description, he seems to understand Shen Kuo's thoughts. This approach sounds familiar. I don't know where I've seen it.

It's just that Su Song and Tang Xun don't have such a good understanding ability as Lu Chengqi, and they are still confused, and they don't know what Shen Kuo is talking about. Lu Chengqi saw the confused look in their eyes, and knew that they didn't understand, so he said, "Shen Qing, how are your painting skills?" Why don't you bring a pen, ink, paper, and inkstone and draw your thoughts, so that it will be clear at a glance? ”

Shen Kuo was worried about how to express his thoughts. Hearing Lu Chengqi say this, he was overjoyed. He immediately said, "Please wait a while, and the minister will go and draw the design." ”

Lu Chengqi nodded, and Shen Kuo did not delay, and walked straight out of the test firing range. As soon as Shen Kuo's front foot left, the two range-measuring apprentices on the back foot turned around. The apprentice on the horse turned over and dismounted, bowed deeply and said, "Your Majesty." We roughly measured that this cannon hit nine miles of land. If you increase the amount of gunpowder and use heavier shells, you should be able to hit the ...... for twelve miles."

Lu Chengqi was taken aback, he vaguely remembered the time when he traveled in Humen in the later life. I heard the tour guide say that the imitation Hongyi cannon on the Humen Fort has the same maximum range as this artillery, or even inferior. In this way, this gun, which was built without any money, already has first-class performance. If it can be equipped with a flowering bullet and increase the rate of fire, it will be a weapon of war! It is not for nothing that later generations will regard the cannon as the god of war. Hundreds of cannons are fired at the same time, hundreds of shells explode in a small area at the same time, where can a living person survive? Lu Chengqi remembered the famous words of a certain German military strategist: "To annihilate the enemy's combat effectiveness with infinite violence, the only way to achieve this goal is the combined impulse of organic power and firepower." ”

In the face of absolute firepower, any resistance looks very pale and powerless. It's not a question of cruelty or not, isn't it cruel to let the enemy rush up and kill you?

The advent of gunpowder weapons must be the curtain of the withdrawal of cold weapons. This is the course of history, and in the face of more effective killing weapons, cold weapons can no longer keep up with the development of the trend. And just at this time, Dashun's cold weapons have also developed to their peak, and the range of the bow and crossbow has approached the limit. The only way to continue to counter the mobility of the nomads with the advantage of weapons is to develop further.

The appearance of Lu Chengqi also filled the flaws of the original historical process. He single-handedly led the development of black and gunpowder weapons, and achieved tremendous results. If the artillery is completed again, then what will the Khitans, Jurchens, and the Mongols that have not yet been formed use to resist the Han Chinese?

After seeing Lu Chengqi's surprise, Su Song and Tang Xun's hearts that had been hit repeatedly regained a little self-confidence.

"I didn't expect the range of this artillery to be so amazing, Su Qing and Tang Qing, you have made a lot of contributions!" Lu Chengqi sighed sincerely, he finally understood now why the Hongyi cannon could be popular in the original history for three or four hundred years, the reason was in the range!

This type of cannon does have advantages in design, the barrel is long, the tube wall is very thick, and it is gradually thickened from the muzzle to the tail of the gun, which conforms to the principle of high to low bore pressure when gunpowder is burned. There are cylindrical lugs on both sides of the center of gravity of the gun body, and the gun can adjust the firing angle with this axis and change the firing range according to the amount of gunpowder; If the trajectory is calculated according to the parabola, the accuracy is very high.

According to the characteristics of Chinese history, when there was no obvious enemy, weapons stopped developing into the city. So much so that later in the Humen artillery battle, on the Humen Fortress, it was still this kind of cannon. Even if it is adjusted to the maximum range, it is not as good as the Armstrong gun of the British! When Lu Chengqi traveled to Humen before his rebirth, he couldn't help but be filled with righteous indignation when he heard this heavy history, and his heart was sullen.

But China's history is like this, biased towards building cities for defense. And this heavy cannon is very much in line with the requirements of defending the city, and is favored by the Chinese, so that for more than three hundred years, there has been no progress except for building more and more heavy. In the later Qing Dynasty, during the Daoguang period, the British used rear-loading rifled cannons, and the Humen fortress still used this kind of Hongyi cannon, in comparison, making every Chinese who cherished the motherland indignant!

Hearing Lu Chengqi's praise, Su Song and Tang Xun said in unison: "This is due to Your Majesty's foresight, and the ministers have no credit, but they just put Your Majesty's ideas into practice." (To be continued.) )
