Lu Chengqi glanced at Su Song and Tang Xun, who were full of unwillingness, and said with a smile: "As for the front-loading artillery, I still have an idea. It's just that it's hard to achieve www.biquge.info with current technology. ”

Sure enough, this sentence attracted the attention of Su Song and Tang Xun, and they asked in unison: "Does Your Majesty still want to build this front-loading cannon?" ”

Lu Chengqi nodded and said, "If you can build a mortar, it's not impossible to build a front-loading gun." "Lu Chengqi, who has watched "Bright Sword", remembers the mortars of the Japanese army the most. This kind of medium-range curved small artillery, if properly manufactured, has a maximum firing range of more than eight miles, and can achieve precise strikes within a kilometer, and is the best support and an effective suppression weapon accompanying infantry combat. The mortar has a large firing angle, a curved trajectory, a small muzzle velocity, a short minimum firing range, and a good killing effect on unprotected targets, and is suitable for shooting at targets behind shelters and targets on the anticline. The most important point is that it is small in size, light in weight and simple in structure. It is easy to operate and has an extremely fast rate of fire. When firing, the recoil energy of the barrel is absorbed by the ground through the seat. When marching, the body tube and seat plate can be disassembled, so it is easy to carry.

It's a pity that such a sharp weapon, with current technology, can't be made at all. Mortars can be made, but the difficulty of shells is too high. Now there is not even mercury thunderate, what to use for fire, caps? Without fire, caps, and impactful shells and bullets, there is no need to think about it. There are no mercury-containing blasters, let alone mercury-free and rust-free blasters. Don't look at a small fire and hat, but it is the embodiment of the industrialization of the whole country.

In a word, chairs, tables, and teapots can be made now, but there is no system for the storage of chemicals. If we start to build a chemical system now, it will take at least thirty or forty years to make fixed metal bullets and shells according to the normal process. A small bullet must contain not only the firing charge, but also nitrocellulose. According to the industrial conditions of this era, there is really nothing that can be done.

When Lu Chengqi talked about the concept of mortar firing and the concept of **** and nitrocellulose, Su Song and Tang Xun stopped talking. They have also been exposed to low-level chemistry, which Lu Chengqi calls naturalism, but also includes physics.

Insiders look at the doorway, and laymen look at the liveliness. Su Song and Tang Xun both know how far away from mortars is with current technology. Even if you spend your entire life researching, it is unknown whether you can see the birth of mortars.

Seeing that they all fell into silence, Lu Chengqi was open-minded. It was beyond his expectation that he could create a Hongxiang-style rifle similar to a Mini gun. Coupled with the concept similar to the Furlong cannon proposed by Shen Kuo, Lu Chengqi was completely satisfied. In time, there was an army equipped with Hongxiang-style rifles and sub-mother cannons, coupled with cavalry on both wings, to protect the riflemen who lacked melee ability. If there really is such an army, what country in the world is the opponent of Dashun? There really comes a day when dominating the world is not a problem. It's just that Lu Chengqi knows very well that with the administrative efficiency of this era, being able to control a country as big as Dashun is almost close to the limit. Dominating the world or something, it's just YY in boredom, no matter how big the territory is, without effective management, it's just a repeat of the mistakes of the Yuan Dynasty.

Tang Xun was a little discouraged, he was the oldest in this, even if there was really a day when the mortar was made, he estimated that it would be difficult for him to see it. When he expressed this doubt, Lu Chengqi smiled and said, "Tang Qing doesn't need to be discouraged, don't you still have students?" That's why I set up Royal Roads University! Talent is the key to a country's progress, if even I don't pay attention to talent, then we Han people will not want to forge ahead. Learning is like sailing against the current, and if you don't advance, you will retreat. Technology is the same, even if it stops, it is also regressing. Because others will not give up progress because of your stopping, one will eliminate the other, and when the day comes, we Han people will become vassals of foreign races. Five chaotic flowers, still remember, beacon Yangzhou Road! Tang Qing doesn't need to be like this, your students are also your extension, what you can't accomplish, just leave it to them. Of course, the premise is that you unreservedly teach these students what you have learned in your life......"

At this point, the three of them finally understood Lu Chengqi's good intentions, and sighed again and again: "Your Majesty is far-sighted, and the ministers will obey!" ”

Lu Chengqi said with a smile: "Although the mortar can't be made, there is a kind of artillery shell that you can make." ”

Su Song asked, "Dare to ask Your Majesty, what kind of cannonball?" ”

Lu Chengqi didn't say it explicitly, but asked rhetorically: "Then I want to test Su Qing, what is the most harmful thing to this solid cannonball?" ”

This question was asked to all three of them. Intuition told them that Lu Chengqi's question didn't seem like a joke, and after thinking for a while, Su Songcai said cautiously: "The minister is stupid, and he thinks that solid cannonballs will kill the city wall the most. ”

Lu Chengqi nodded and said, "Yes, the solid cannonball does a lot of damage to the city wall. No matter how thick the city wall is, the bombardment of hundreds of cannons can always make a gap. If it is directly bombarded at the city gate, it is not a problem to blast out a gap. But the question is, how many cities can Liao have? However, such shells are good for use on new warships. One shot blasted the enemy ship out of a gap, and after a few shots, the enemy ship sank. In this way, broadside battles are avoided. ”

Shen Kuo saw that Lu Chengqi had analyzed the advantages and disadvantages of solid shells, but he didn't say the key points for a long time, and couldn't help asking: "Then what does Your Majesty think is the best?" ”

"Of course it's a flower!" Lu Chengqi said without hesitation.

"Blossom bombs?" The three of them said in unison, puzzled.

Lu Chengqi explained: "This flowering shell is a hollow cannonball, that is, more than half of the black powder in the shell, don't fill it, you can also fill it with iron sheets, iron nails or something. The shell should be thinner and fitted with a fuse so that the shell ignites and explodes when fired. In this way, the lethality of enemy soldiers will be much greater. ”

Tang Xun pondered for a while and said, "Your Majesty, can such a cannonball really be shot?" ”

Lu Chengqi said with a smile: "I just provide an idea, as for whether it can be done, you have to conduct an experiment!" ”

Su Song said confidently: "There is no big problem with making such a cannonball. However, how much gunpowder to put and how to install the lead still had to be experimented with many times. ”

Shen Kuo was not very familiar with iron smelting and did not express his opinion. Tang Xun listened to Su Song's words, nodded, and said, "If it's a hollow cannonball, just make an iron mold, it's not much trouble." However, how to put gunpowder, and the iron pieces and nails that His Majesty said, must be constantly experimented to come up with the best method. ”

Lu Chengqi nodded and said, "My idea is that there are two kinds of shells, which can be used according to the occasion. Solid shells are used when dealing with enemy ships and cities, and flowering shells are used when dealing with enemy cavalry in field battles. (To be continued.) )
