Seeing that Tang Ruowang was holding two of Sun Yuanhua's "lost" military writings for many years, Hongyi was very pleased - first, he could let the old foreigner pick up the gaps and help the Qing Dynasty; Second, I was surprised to learn that in the eyes of Westerners in this era, my Chinese firearms technology is still unique, and it is not so unbearable! [Interested readers here can refer to a copy of the Commercial Press's "History of the Western Spread of Chinese Culture to Europe", written by the French scholar Yasuda Park, who Hongyi has been reading recently and has benefited a lot!] But remember to buy the original version! ]

However, at this time, Tang Ruowang no longer bothered to ponder the thoughts of this young master, and had already held the two military books, especially the "Western Law Divine Machine", and looked at them at a glance and ten lines, nodding while reading, or thoughtfully, and then suddenly realized.

"Old Marfa, can this book be used?" Hongyi asked with a smile.

"It's not just 'usable', sir! It's just incisive! John Tang couldn't hide his excitement at this time, and said in one breath:

"Master, look at this - the book emphasizes that the manufacture of firearms needs to be 'inferred by example', that is, those who make and use firearms must have a precise quantitative concept, and regard it as the law, and cannot be wrong by the slightest. The so-called 'casting of big guns, the system of length, size, thickness and scale, is really cautious, and does not dare to be clever in vain, creative and vain, so as to make mistakes. It must be based on a certain true transmission, compare the degrees, and deduce its law.' If 'the idea is false, and the thing is wrong'. In other words, if the length, size, and thickness of each gun do not fit in harmony, the advantage of firearms will be lost. The so-called 'comparative degree' and 'proportional calculation' are actually not fixed. Because for different materials, the length, size, and thickness of the firecracker should also be different, so these measurements and proportions are actually the accumulation of many years of experience and the summary of countless practices! That's a great point to say! ”

"Well, that's reasonable......" Hongyi didn't plan to comment too much, he just wanted to leave time for real experts. Sure enough, John Tang continued:

Sun Chuyang also believes that the power of the gun and whether it can hit the distance depends on whether the manufacture of the gun barrel is reasonable and whether the preparation of gunpowder is appropriate, and whether the iron bullet is manufactured correctly is also very important. Therefore, he demanded that the size of the bullet must be in accordance with the caliber of the gun. If the bullet is big, it will be difficult to export. Gun tubes are easy to fry; If the bullet tube is wide, the drug power is easy to leak, and the firing range is short and weak, which not only wastes labor. It will also delay the war. Only the size of the bullet matches the caliber of the gun. in order to hit far and powerfully. How right! ”

This time. Hongyi was not perfunctory, because in Tang Ruowang's interpretation, he suddenly remembered a key point. So he hurriedly interjected:

"Old Marfa. In your opinion, what is the stage of today's Chinese and Western weapons? ”

"This ...... The old minister thought that it was the parallel of bows, spears, swords and firearms and artillery. I don't know what the master has to teach you? Tang Ruowang promptly changed his academic thinking to the "response mode" and carefully served Xiao Xuanye in front of him.

"That's right, the parallel of bows, spears, swords, and firecrackers and artillery is not wasted, that's great!" Hongyi high-fived and laughed, and continued:

"In the battle formations of the countries of Europa, it is indeed the cooperation of spearmen and musketeers, and both are indispensable. Old Marfa's analysis is extremely exquisite! ”

"The master has won the prize."

"Then I'll elaborate on your understanding. Xuan Ye thought that before the advent of the fire gun, it was the era of 'cold' weapons: no matter what kind of weapons such as bows, spears, swords, stone throwing ladders, etc., they all relied on the samurai's own strength, fighting and stabbing, and fighting with strength. But since the advent of firecrackers and artillery, it has been the era of 'hot' weapons. Even the most thin soldier can kill enemies in the distance as long as he holds a gun in both hands and lights a fire rope, supplemented by cold weapons, which can be said to greatly increase his combat power. Hongyi slightly "popularized" the view of the history of weapons to Tang Ruowang, but it was just a stage division. After all, a concluding speech can't be regarded as a "golden finger"!

"Oh, the master's analysis is reasonable, and the old minister has been taught!" John Tang pondered it carefully, and was really amazed.

"Old Marfa is not in a hurry to praise, Xuan Ye has not finished speaking." Hongyi waved his hand, signaling that he would continue.

"But as soon as the bird came out, the situation was different again. In particular, with the addition of the Gun Bolt [Sight], the Gun Stock [Gun Stock], and the Gun Machine [Bolt Machine], you can fire the gun in one hand and the other hand without having to raise the fire before each shot, and you can also do a 'aiming'. Once the gunpowder is ignited, the projectile will slip out, and the momentum will be like a bamboo! After the bird gun hand is familiar with the practice, he can really hit every shot like a sharpshooter! Besides, the archer can't be done by everyone, but the bird gun is easy to operate, and everyone can get started with diligent practice. In this way, I thought that weapons had entered the 'smoothbore era'! What do you think, old Marfa? ”

"This, Lao Chen really didn't expect. Smoothbore out...... The Smoothbore Era? You're saying that this bird can do a lot in the future? "John Tang is really an expert talent!

"Exactly! And today's bird guns should be more precise and powerful in the future. Wasn't there already flint in the Rakshasa bird's guns captured in the Battle of Humar? Arquebuses are still available, but in the future they will be the world of such flintlock pistols! ”

"Fusiliers...... Master, the old minister remembers, is the flintlock pistol you are talking about the Flint-lock invented by the French decades ago? John Tang asked tentatively.

“Flint-lock？ Old Marfa, tell me about it. Hongyi didn't dare to assert.

"Oh! This Flint-lock was founded in 1620 by Marin of France. Invented by Bourdhiva, this gun was mainly used to hit the flint on the lid of the cauldron with a hammer to ignite the spark, and then ignited the cauldron, thus replacing the fire rope. Tang Ruowang spoke eloquently, but seeing that the master still didn't speak, he added:

"It's like Bi Maokang's 'self-generated firebolt' in the former Ming Dynasty."

"Oh, I see! You're right. However, instead of using the original spring wheel structure, the Flint-lock uses a hammer instead, which is more concise and fast! Hongyi finally understood, and quickly added.

I was stunned just now, because the history of the flintlock pistol that Tang Ruowang said was not consistent with the knowledge he originally consulted on Du Niang. He always thought that the "flintlock pistol" invented by the Frenchman Mahan in the middle of the 16th century is still an advanced weapon in Europe, but who would have thought that more than 30 years ago, the French had improved to the "ramming flintlock pistol". Naturally, this is incomparable to the domestically produced "revolting flintlock pistol" -- the "self-generated firearm."

"Master Shengming! It's a pity that ......" John Tang didn't say much, which made Hongyi a little dissatisfied, and thought he was deliberately hiding something.

"What's the pity?"

"It's a pity that this flintlock pistol is only used in France today, and European countries have no law."

"Really? Don't even have a Dutch red hair who is good friends with France? Hongyi blurted out. Thanks to the Thirty Years' War in Europe, France and the Netherlands were still on close terms at this time. France actually believed in Catholicism, but at that time, in order to dominate Europe, it sided with the Protestant countries of Denmark, Sweden and the German Protestant princes, and was supported by the Netherlands, England, and Russia against the Holy Roman Emperor, the German Catholic princes, and the Catholic side of Spain and Poland.

"This? The United Province of the Netherlands is a heresy of the Darwinians, and the Jesuits are at odds with it, and the ministers do not know it......" John Tong avoided answering, but just acquiesced to Hongyi's speculation - the Dutch have technology, and this is easy to do! So, Hongyi smiled, made up his mind in his heart, and continued:

"In that case, we have to ask your fellow brothers to keep an eye out for it in Europato."

"The old minister wrote it down." Tang Ruowang was still a little stupid, and he couldn't understand how the young master could be so accepting and tolerant of all kinds of perverse acts of heretics.

"Oh, and since we have entered the smoothbore era, then I think that old Marfa needs to make some preparations in some aspects." Hongyi saw the old man's displeasure, but ignored it. Sometimes, isn't it more in line with the needs of the "superiors" to be detached and confused?

"Please also show me." Sure enough, when it comes to work, John Tang must be in good spirits.

"Shicai, you said that Sun Yuanhua's book also mentions 'comparison degree' and 'proportion calculation', I don't know what you think?"

"It's important here, but it's hard to do. After all, craftsmen are different, and there are many differences in techniques, which is really easier said than done! It also shows the far-sightedness of Brother Chuyang. Speaking of the parishioners whom he highly admired, John Tong couldn't help but sigh.

"Not bad! Nowadays, it is indeed easier said than done. But are we going to go on like this? Isn't there a good way to deal with it? Hongyi stared at John Tang with anticipation.

"This ...... And how can it be changed? Old Marfa looked helpless.

Well, you know you can't do it, so listen to me!

"A limerick poem. Hidden Head

Reading literature and reading history is only a long breath

I was saying that there was an opportunity back then

The layout is a long-cherished wish

It's hard to come and go

Get up and spend a hundred years

Point out the suffering and diseases of the world

The edge of the town was razed to the sea
