This is a characteristic of Chinese officialdom, all the credit is the leader, and he is just a cow horsepower. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoIf you take the credit on yourself, it will not be far from the time when the leader will give you small shoes to wear.

Lu Chengqi was not surprised, and he did not delve into the meaning. This credit is real, will he still erase it? It is estimated that Su Song and Tang Xun also have this idea, and Lu Chengqi didn't bother to expose it, but said: "Su Qing, Tang Qing, this artillery you cast is a milestone. The firing range far longer than that of the trebuchet and the bed crossbow is the advantage of this artillery, and when used to defend the city, it can make the city impregnable. It's just not suitable for loading on new warships, and it's not suitable for field warfare. The two Qing families also know the iron cavalry of the Liao, with the rate of fire of this artillery, how many cannons can be fired before the enemy gallops into the military formation? ”

Su Song admitted this, it was true that they didn't think strictly enough. It's just that they have really done everything they can to do everything they can, but they still can't solve the problem of barrel leakage. In desperation, the only option was to choose a front-loading smoothbore gun.

Seeing that they all lowered their heads and looked thoughtful, Lu Chengqi smiled and said, "Being able to do this is beyond my expectations." Now it's idle to wait for Shen Qing, so it's better to use these three rear-loading guns to shoot a few shells, so that I can see why they are failures. ”

Tang Xun had entered the officialdom for a few years after all, and when he heard this, he hurriedly bowed down and said, "Obey the order!" ”

Then it was time for the two apprentices to perform, and surrounded by the two of them, Lu Chengqi entered the stone house again. This time, there was no need to use the past, Lu Chengqi asked each rear-loading cannon to test fire more than two cannons in a row, and this time the two apprentices had no excuse to hide in the stone house again.

"Boom !!"

"Bang !!"

"Woo !!"

……

Listening to the sound of the three cannons being completely different, Lu Chengqi could conclude which one was okay and which one was the failure of the failures. But it has to be said that this rear-loading gun did increase the rate of fire. Lu Chengqi estimated that after a shot, it would only take about three minutes to launch again. And there is no need to adjust the angle of the muzzle, and the reload speed goes up all at once. Probably also related to proficiency, according to Su Song, this rear-loading cannon has been drumming for more than three months, and these two apprentices are operating the artillery, and it is understandable that they are proficient.

Not long after the sound of the cannon stopped, Shen Kuo walked into the stone house with a proclamation whose ink had not yet completely dried, and said to Lu Chengqi: "Your Majesty, the minister has already drawn it." ”

Lu Chengqi asked the two apprentices to measure the range of these three cannons again, but Su Song had already given the answer: "Your Majesty, the range of these three cannons is 500 steps, 1,000 steps, and 1,200 steps respectively. ”

Lu Chengqi nodded, mentally prepared, such a range was still expected. The gun body leaks, and the black and gunpowder cannot fully burn and explode, and cannot provide sufficient kinetic energy, so the firing range will naturally be much closer. There can be more than 1,000 steps, which is beyond Lu Chengqi's expectations. This also gave Lu Chengqi confidence that the rear-loading gun would definitely go to the next level! Even if it can't reach the range of the Hongyi cannon, half of it is a success!

Lu Chengqi didn't believe it, as one of the smartest races recognized in the world, foreign devils can build a rear-loading cannon, but the Chinese can't make it! Even if it costs a lot of money, it is worth it to build a cannon that reloads quickly and can fire flowering shells.

Motioned for Shen Kuo to start the introduction, and Shen Kuo also understood, and spread out the propaganda in his hand on a dusty wooden table. Lu Chengqi leaned over to take a look and praised sincerely: "Shen Qing's painting skills are much better than mine!" ”

Shen Kuo hurriedly waved his hand and said, "The minister doesn't dare to ......"

Lu Chengqi said with a smile: "What don't you dare, there is a specialization in the art industry, my painting is really not very good, and it is not ashamed to admit it." Is it true that if you become an emperor, you must be better than you in everything? So what else do I want you to do? ”

The speaker was unintentional, the listener was intentional, and the three people present listened, and they all looked at each other, not knowing what to say. Lu Chengqi didn't say nonsense, Shen Kuo, as the author of "Mengxi Writings", there is no need to talk about his painting skills, although this book has not yet come out......

Lu Chengqi stared at the drawing, which drew a large cannon barrel and a small cannon barrel. Shen Kuo explained: "This is what the minister said, the bullet of the artillery. It's just that the bullet doesn't go out, but the shell in the bullet fires. When loading, you can have a few more bullets, and when one is fired, you can load the second. In this way, the reload speed is faster. In addition, this bullet is also a part of the cannon body, as long as it is measured properly, it is a sure fit! Seeing Shen Kuo's confident appearance, Lu Chengqi was also infected.

Suddenly, Lu Chengqi knew why this design looked familiar, and he shouted: "Isn't this a Franc machine gun?" ”

Shen Kuo was stunned for a moment and said, "What cannon?" ”

Lu Chengqi knew that he had missed his mouth, and hurriedly said: "I am saying that this cannon can be called a sub-mother cannon." ”

As soon as these words came out, the three of them agreed: "Your Majesty's name is really appropriate." A cannon like a child and mother cannon, called a child and mother cannon, is very suitable! ”

Lu Chengqi was once again shocked by the whimsy of the ancients, and the Furlong machine gun that he didn't expect was actually invented by Shen Kuo. Although the details of this Franc cannon have not yet been perfected, the idea of the sub-mother cannon is real. As for the details, it is okay to wait until the gun body is cast and then add it according to the actual situation.

What is a Furlong cannon? In the official history, in the middle of the Ming Dynasty, this kind of artillery was introduced from Portugal, when the Chinese called Portugal "Franc Machine", so this artillery was also named "Franc Cannon". The Furlong cannon is a reloader smoothbore cannon. It is composed of a mother cannon and a sub-cannon. The barrel of the mother gun is slender and the caliber is smaller. The rear part of the gun is thicker, and there are long holes and grooves to fill the guns. Like bullets, each mother gun has 5 to 9 subguns, which can be preloaded with ammunition for backup, and the mother cannon can be loaded and fired in turn during battle, thus increasing the firing speed.

It's just that because of the caliber, the firing range of this type of artillery is not far, only about one to four miles, and at four hundred paces, the accuracy is the best. But if it is cast into a thousand-pound cannon, it must not be inferior to the Hongyi cannon!

The more he looked at it, the more shocked he became, if it wasn't for the confirmation that Shen Kuo was not a reborn person, Lu Chengqi would have really met his companion. After understanding the principle of the sub-mother cannon, Lu Chengqi sighed: "Such a whimsical idea, only Shen Qing can think of it!" In my opinion, this sub-mother cannon is far better than the Hongyi cannon. In this way, I ordered Shen Qing, Su Qing, and Tang Qing to work together to cast the cannon, no matter what method you use, you must get this sub-mother cannon out of the drum as soon as possible. The range doesn't need to be too far, and it can be two or three miles, which is enough......" (To be continued.) )
