The three of them thought so, to be honest, if it weren't for the help of the students of Royal Roads University and the apprentices of craftsmen in the Ordnance Prison, it would have taken five or six years for this sub-mother cannon to be built by the three of them alone. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoThe formation of an artillery requires not only skilled blacksmiths, but also designers and computing talents......

Shen Kuo cautiously asked, "Your Majesty, do you still want to continue firing?" ”

Lu Chengqi shook his head, he already knew the loading speed of the sub-cannon, and then he wanted to see the range of the sub-cannon. "Send someone to measure the range!" Lu Chengqi said lightly.

Shen Kuo heard this, raised the small flag in his hand, and shook it regularly, and those apprentices immediately stopped moving, extinguished the fire, and took a few steps back to the side to stand. Then the apprentice who adjusted the artillery turned around and waved his hand, and Shen Kuo saw it before saying, "Your Majesty, there is no danger ahead, you can go and check." ”

Lu Chengqi nodded and slowly walked out of the stone house. They walked to the mother and son cannon, and Lu Chengqi once again tested the temperature of the cannon body, and found that it was only slightly hot, and there was no overheating. This is all due to the thick barrel of the cannon and the excellent steel smelted by the Ordnance Superintendent. Of course, no matter how good the steel is, it can't compare to the future generations, and this is just relative.

Lu Chengqi nodded and said, "I am very satisfied with this sub-mother cannon!" ”

Being able to get the approval of the little emperor, Shen Kuo, Su Song and Tang Xun all showed excited expressions on their faces. Yes, for this artillery, it took them two years to set up a secret team to find a usable artillery. It's like his own child, who was praised by a great Confucian for having a future, and the pride in his heart has exploded.

Lu Chengqi said: "How many of these sub-mother cannons have you built?" ”

Hearing this, the three of them looked at each other. After being silent for a while, Su Songcai said: "Your Majesty, it is this sub-mother cannon, which has taken more than half a year. We really don't have the energy to rebuild another one. However, Your Majesty can rest assured that if you go all out to rush the work, you will definitely be able to equip all the new warships this year. ”

Lu Chengqi calculated that there were about 200 new warships, and if each ship was equipped with four, that is, there were 800 guns. If there were more equipment, wouldn't it be a thousand? Don't say that now, even if the future generations want to build thousands of artillery, it will take two or three years. In this year's time, the Ordnance Superintendent will complete its task, which is simply impossible.

Lu Chengqi said lightly: "Su Qing, this science is a science, and we have to pay attention to seeking truth from facts. There are more than 200 new warships, how can they all be equipped in one year? I don't want you to rush to work, within a year, to ensure the quality of artillery, take out 200 sub-mother cannons, Dashun is already invincible in the world. ”

Su Song's face was hot, and he felt very embarrassed that he knew that the Haikou he boasted about was ruthlessly pierced by the little emperor. Shen Kuo hurriedly said: "Your Majesty, the casting of the sub-mother cannon is cumbersome, and if it is based on the current scale of the Ordnance Prison, it is difficult to have two hundred. Su Jianzheng meant, can you recruit more apprentices? ”

Lu Chengqi was stunned for a moment, and laughed and said: "If the ordnance supervisor wants to develop, can't I get stuck with you?" You don't have to think too much about anything else, just do what you have to do. On the side of the household department, I have already made a decree, as long as it is the fee that the ordnance superintendent wants to apply, it will be approved at the same time. Isn't it easy to recruit some apprentices? The students of Royal Roads University, if they want to stay in the armory, they should be recruited. These are the children of a good family, and they can be trusted. If you recruit other places, you still need to be strictly reviewed, don't let the spies find out the details of Dashun. ”

"Yes!" The three of them said in unison.

Lu Chengqi walked to the side of the cannonball, picked up a heavy solid bullet, and said in his heart: "This iron lump, at least seven or eight catties, right?" Such a big iron bump is lucky to hit a person's body, and the tendons are broken and fractured...... Hey, what is it? ”

He picked up a "fluttering" iron bump, only to see that under the reflection of the sun, the iron bump was covered with potholes, as if it was about to crack at any moment.

"Could this be a flowering bomb?" Lu Chengqi thought so in his heart, shook his hand casually, and found that the inside was really hollow, as if there were iron pieces hitting each other inside, making a pleasant sound of "jingle bell".

Tang Xun said: "What Your Majesty has is a flowering bomb." ”

Lu Chengqi said with interest: "How did you achieve unity? ”

Shen Kuo explained: "Back to Your Majesty, this flowering bomb is not a complete one. If Your Majesty takes a closer look, you will find that one end of it is made of molten iron poured into it. The method we came up with was to make a hemisphere that could be stuffed into iron sheets, and after cooling and forming, we would stuff in iron sheets, tribulus terrestris, and iron nails...... Then it is infused with molten iron. We had previously tried to fill the shells with gunpowder, but there was an accident. Therefore, we have to settle for the next best thing......"

Lu Chengqi was a little surprised: "Then why do you want to use molten iron to infuse?" Wouldn't it be the same to put the lead wire on and use a wooden stopper? ”

When the three of them heard this, their eyes lit up: "Yes, why didn't you think of it before?" ”

In fact, in their thinking, cannonballs should be made of iron, which leads to misunderstandings. In fact, it is far easier to manufacture flowering bullets than solid bullets. After all, smelting an iron lump of seven or eight catties or more than ten catties is not as simple as a flowering bullet made according to a model. If what Lu Chengqi said is really effective, then it will be much simpler to produce flowering bombs.

However, Tang Xun still had doubts: "Your Majesty, such a cannonball is too dangerous." If the lead is too short, won't it explode in the barrel? ”

Lu Chengqi nodded and said, "This is indeed a problem...... This requires the gunners to be well trained, and this is not what you have to do, but what the border army of the forbidden army has to do. ”

As he spoke, the apprentice, who had measured the range, rode back on his horse. After turning over and dismounting, he bowed down and said: "Report, the range of two shots has been measured, the first shot range is seven miles and sixty zhang away, and the second shot range is eight miles ......."

Lu Chengqi nodded, he knew that it was all because of the recoil, which made the gun carriage move back a little bit, and also made the muzzle of the gun slightly raised, which made the range deviate. Even so, Lu Chengqi was also greatly pleased with the power of the mother and son cannon, the range was not inferior to the Hongyi cannon, and the reloading speed was greatly improved. If you are proficient, I am afraid that you can control it to one shot in 20 seconds. With hundreds of artillery pieces and a salvo fired in twenty seconds, how spectacular should that scene be?

That scene was too beautiful for Lu Chengqi to imagine. What he wanted to know most now was how far the cannon could shoot with flowering shells. If there is a range of three miles away, who else in this world would dare to beat the edge of Dashun?

"Now that the range has been measured, let's try the range of the flowering projectile, I can't wait to see what happens!" Lu Chengqi said lightly in an unquestionable tone. (To be continued.) )
