Wang Lin was stunned when he heard this, and then said: "Lord Li, since the telescope in your hand is made of glass, presumably Lord Li must know how to make this glass, I wonder if it is convenient to make it now?" Speaking of this, Wang Lin smiled and said: "I also know that Lord Li has a lot of opportunities, and such trivial things naturally can't spare time at present, but our current government army has also begun to take shape, and it is also equipped with artillery made by us, but at present, there is only artillery, if there is no long-range reconnaissance tool, the power of artillery will be greatly reduced."

Li Xiang heard this, thinking that this is also reasonable, even if there are dozens of artillery now, if you want to fight against the Mongolian iron cavalry, it is bound to be defeated, it seems that not only the artillery, telescopes, etc. need to speed up the production, but all other aspects must be prepared as soon as possible.

Li Xiang also thought about it at first, and even thought that if the production of artillery continued, with hundreds of pieces of equipment in the government army, he would have the certainty of resisting the invasion of Sichuan by the Mongol iron cavalry. Now that only a few dozen artillery pieces have been built, all the iron in the entire Shaoxi Mansion has been used up, and of course, the imperial court is also mobilizing iron materials, but it is better to be able to solve the source of iron by yourself.

Moreover, the service life of this batch of artillery is not too long, and it seems that if the problem of raw material production and processing technology is not solved, it can only be thought about to manufacture artillery in batches.

Li Xiang knew that in history, the combat power of the Southern Song Dynasty army was not weak, and when it came to the time of joint attack with Mongolia, it was much stronger than before, and the army construction had made great improvements, and it was precisely because of this that the Southern Song Dynasty was able to fight against Mongolia for decades later, only because of the new weapons that were widely used when Mongolia went west, and there were many long-range attack weapons from West Asia.

But now that he has come to this world, he can't let history repeat itself, of course, now the Great Song Dynasty is not only making artillery in Shaoxi Mansion, but the most important place is the Ordnance Supervisor in Lin'an, Li Xiang knows that he is making artillery in Shaoxi Mansion in order to prepare for the development of his own power and territory in the future.

Thinking of this, Li Xiang hurriedly said: "Lord Wang doesn't have to be too anxious, in fact, it is not difficult to build a telescope, and there are many forms of telescopes, not only glass and crystal can be made, but it involves a wide range of knowledge, and to make it, it also needs a group of skilled craftsmen, and more importantly, these theories need to be studied in the laboratory before they can be used in practice in the factory, but now only this small house is used as a laboratory, to create many advanced weapons, but it is absolutely impossible." ”

In fact, the production of telescopes is not too difficult, the natural crystal with high transparency can make a good telescope, the crystal is ground into a disc shape first, and then two crystals are added to the fine sand to grind, and finally polished with asphalt, and then parabolized, you can complete the convex mirror and the concave mirror at the same time.

In fact, modern astronomy enthusiasts use this method to make large-aperture Newtonian reflecting telescopes, because the principle of reflection is adopted, so the ordinary cabin glass can meet the requirements, but the technical requirements are very high in grinding, and after grinding, parabola, grating correction, polishing, and aluminum plating, after a number of complex processes can complete the grinding of a reflective primary mirror.

But according to the current situation, the telescope does not need too many requirements, nor does it need to consider the problem of chromatic aberration, as for the lens tube, it is completely possible to roll up multiple layers of paper. In fact, the self-made small-aperture astronomical telescopes in the 80s made their lens barrels in this way, but most of the lenses were purchased off-the-shelf. Because of this, Li Xiang is still full of confidence in building telescopes.

Wang Lin listened to Li Xiang's complaints, and there was no good way for a while, so he thought for a while and said: "Since Lord Li has a way to make a telescope, other things will be arranged by Wang. Wang Lin is now completely involved in Li Kang's father and son, and he is not stupid, so he can naturally see that this father and son will definitely become a big thing.

Li Kang smiled: "Xiang'er, Lord Wang is a person who can be trusted. Now these dozens of artillery pieces are not badly trained in the artillery battalion. ”

Li Xiang nodded and said: "Yes, now we not only have to make artillery, cannonballs, but also glass, mine salt, and most importantly, prepare to open iron ore to make iron, many things need manpower!" Lord Wang is very good in this regard, and can find more capable people for us. Now our artillery is not powerful enough, and we need to continue to improve. For example, solid bullets, less powerful, it can kill and injure people and horses, and can destroy field fortifications such as fortresses, because its trajectory is low, the damage caused is straight, so dense infantry columns and infantry phalanxes can often be used to attack, while thin infantry columns and cavalry are not suitable for the use of such shells. ”

According to historical records, solid artillery shells in the early Qing Dynasty could easily penetrate a column of 20 rows of infantry, and ricochets on hard ground still had great lethality. However, the disadvantages of solid shells are also obvious, and the low trajectory makes it difficult to effectively hit enemy units located on the anti-slope of the hillside.

Li Xiang said again: "As for the scattered bullets, you can deal with dense close-range cavalry, and if you want to deal with long-distance cavalry, you can reduce the number of scattered bullets and increase the projectile." In addition, against the enemy at a long distance, you can also use the kind of artillery shells that can explode, in fact, this kind of shells are also called grenades, this kind of shells can actually be fired with another kind of artillery, the trajectory should be curved, so that it can make up for the lack of solid shells, in addition to being used to deal with the troops behind the hillside, the grenade has a considerable lethal effect on the enemy troops of various formations on the open ground, and the ideal impact point is the front of the target team, or it is best to burst above the enemy queue. Li Xiang spoke so eloquently that several people were already stunned.

Li Xiang said, and drew the ballistic trajectories of solid bullets, scattered bombs, and grenades one by one, Wang Lin and the others had already admired Li Xiang so much, but now they were greatly shocked, thinking how much else does this Lord Li know?

Wang Lin saw that Li Xiang didn't seem to have the intention of making howitzers immediately, so although he was anxious, he didn't want to ask, but Li Kang thought that if both kinds of guns could be equipped with hundreds of guns, then this army could be said to be invincible.

Li Xiang looked at everyone's expressions, already knew what everyone was thinking, and said with a smile: "You don't have to be anxious, after a few ****, I will explain the production method of howitzers to Lord Wang, and there is another weapon that can also be considered to be manufactured, in fact, it is a musket, and you can try to study it here in the capital first." ”

Time passed quickly, stayed in the capital for a morning, arranged the work, and Li Kang and his son returned to the mansion. (To be continued.) )
