"Chen Langzhong, what are you doing in the Ministry of Industry?" Zhang Mingde asked.

Chen Fei immediately said: "Lao Zhang, didn't you come to the Ministry of Industry?" I want you to introduce me to that Yu Langzhong, what do you think? I'm going to get some brass from him, I'll be of great use. ”

Zhang Mingde said helplessly: "Chen Langzhong, I'm afraid it's a little difficult!" I also have a general understanding of Duan Langzhong of this Yu Department, he has a bad temper and a hard temper, and I, a newcomer, know it. So you don't have to look for him, it's useless to look for him. If you really want it, then you have to go to the emperor. This matter cannot be decided by the Ministry of Industry without authorization, because this is a matter related to the coinage supervision supervised by the Ministry of Households, and it is related to the finances of my Datang, and the Ministry of Households will not sit idly by. If the copper used for coinage is transferred to your ordnance supervisor, then I am afraid that in the end, it will cause trouble between the household department, the engineering department, and the military department, and it will be a lot of trouble. ”

Zhang Mingde's words are not unreasonable, Chen Fei wants these coppers, but copper was a metal used to mint money in ancient times, and this is related to the vital interests of the household. The household department manages the finances, and the amount of copper money determines the amount of their finances, especially when it is related to their vital rights, and they must not be given to others casually. If the Ministry of Industry gave these coppers to Chen Fei without authorization, then the Ministry of Households, the Ministry of Industry, and the Ministry of War would make trouble with each other, so that no one would be able to please them.

"It seems that this matter can only be handled by Li Shimin, the emperor, himself. If the emperor didn't coordinate it personally, I am afraid that it would not be able to solve this problem! Chen Fei thought.

After a while, the hall of two ceremonies.

"Your Majesty, the minister wants to make a special weapon, which is very powerful, but he needs a large amount of copper to cast copper coins, and he asked the emperor to take out some for me to try to make." Chen Fei said.

Li Shimin frowned, and then asked, "Copper?" Our dynasties have not been used to forge weapons for many years, at least for thousands of years. What weapons can be made out of copper? ”

Li Shimin is still inertial thinking. Think of this as a cold weapon. In fact, in the era of cold weapons, since there was iron, they would not use bronze to make weapons. Because copper is not only expensive, but also relatively soft weapons, it is not suitable for making the kind of cold weapons that rely on sharpness and hardness to win. Therefore, in the later period, copper was used as coinage, and also used as ornaments and other bronze utensils, and there was no great use in other places. However, Chen Fei wanted to use this copper to cast weapons, which was obviously a bit too surprising.

And China has not been a place to produce copper ore since ancient times, so copper is not enough to make money, let alone use it as a casting weapon? So Li Shimin didn't want to agree at first, after all, if copper was used to make weapons. That's probably going to cost a lot of copper.

"How much copper do you need for this 'weapon'?" Li Shimin asked.

Chen Fei replied: "Each cannon, let alone more than 600 catties." ”

"No, no, I don't know how much money I can mint for six hundred catties of copper, and I definitely can't agree to this!" Li Shimin said.

Although Li Shimin didn't know how powerful this weapon could be, more than 600 copper was enough to make an unknown amount of copper coins, and if there was less of these, it would have some impact on the economy. Therefore, the Li Shi Militia Department intends to agree to this, so he will not approve of Chen Fei's suggestion.

"Your Majesty, I haven't finished talking yet, this weapon is hugely powerful." Chen Fei said.

"It's so powerful. Each use can cause the enemy to lose about 30 people, and these 30 people will be seriously injured if they don't die, and they will not be able to fight. Chen Fei said.

"Oh? What weapons? Li Shimin asked.

Li Shimin was really interested, because if he could make the enemy lose about thirty people each time. That's a very good weapon, and it's hugely powerful! However, it depends on other parameters, if other parameters can satisfy Li Shimin, it is not impossible to use as a weapon for his own troops. If other parameters don't work. Then don't use it.

"Your Majesty, you can fire about three or four times a minute, and each blow is about thirty people. And a minute is one-fifteenth of a quarter of an hour. And this kind of artillery can hit more than two miles, so the power is huge? Chen Fei said.

And Li Shimin's eyes are straight, what kind of "artifact" is this! If we deduce according to this theory, it can hit more than two miles, and if we follow the advance speed of the infantry phalanx in this period, I am afraid that it can advance about 120 steps per minute, that is, 60 meters. And in a place of more than two miles, it takes at least 20 minutes, and this "artifact" can be fired three or four times per minute, so let's calculate it according to three times, then at least this "artifact" will be fired more than 60 times, and each time the enemy will lose about 30 people, and those 20 minutes will be about 2,000 people.

This kind of "artifact" caused the enemy to lose more than 2,000 people before he could fight the enemy, Li Shimin really wanted to point at Chen Fei's nose and ask if this was a fairy weapon!

"Really, they were able to make the enemy lose two thousand men without contact?" Li Shimin asked.

Chen Fei shook his head and said, "Your Majesty, this is just a theoretical calculation, and it can actually reach one-third, and it is already blessed by the gods and Buddhas." And I guess the enemy couldn't hold it at all, and when he found out that the situation was not right, he immediately ran. When the time comes, it will be difficult to hunt them down with the weight of 600 catties of this weapon. Therefore, this can only be used in positional warfare, and once the enemy retreats, it cannot be pursued. However, this weapon can completely eliminate nearly half of them immediately before hand-to-hand combat. Even before they could rush in front of us, they were going to be defeated. ”

"Enough is enough, even if I can make them lose two hundred men before the war begins, I am very content. If each cannon can make the enemy lose 200 men before the battle, then ten cannons is 2,000 people, and 2,000 people are enough to drive 20,000 people to retreat, this is an artifact! You can rest assured to get it, I will carry it for you, as long as you get it out, I will give you a knighthood. Li Shimin said.

Li Shimin really spent his blood for this "artifact", and he was willing to give Chen Fei a knighthood as a price. However, this kind of artillery is also a super artifact for Li Shimin, if he can get it, then no one in the world can be the opponent of the Tang Army. (To be continued......)
