Lord of Ming Dynasty

Some even replaced Zhao Siyang's artillery battalion, Zhao Siyang's artillery battalion now has five, two in Jinhua Prefecture, two in Taizhou Prefecture, and one in Chuzhou Prefecture. Go to a regular army barracks, plus the strength of Qianhu's guards' general banner.

It is enough to defend three prefectures, but if you want an expedition team, you have to gather them together. The Ming army has cannons, and the Qing army also has cannons. At the beginning, the Qing army Dorobel used [-] cannons to attack Jinhuafu. Zhu Dadian's troops suffered heavy casualties. If Zhang Qiang hadn't appeared, the Jinhua massacre would have happened, just like in history.

This artillery is not enough to deal with the Qing army.

There are ten cannons a day, and in a month, as long as the raw materials and workers can be satisfied, there are more than 300 cannons.

Zhang Qiang was startled by this number. It only takes one month for 100 cannons, and all five of his artillery battalions can be completely refitted. In half a month, the artillery can be familiarized and run in. With his current Jinhua Rebel Army site With waterways extending in all directions and land routes extending in all directions, it only takes half a month to reach any direction at any time, no matter which direction the enemy attacks from, the five artillery battalions add up to more than [-] large and small artillery pieces, no matter which direction It is impossible for all enemies not to be wiped out and not to be deterred.

Zhang Qiang immediately made a decision to build ten more artillery battalions.

At that time, two hundred cannons, ten artillery battalions, and ten to twenty thousand troops will be able to attack the Qing army in other directions at any time.

"It saves the time for our clay molds to dry. After the first month of familiarization, the iron molds used repeatedly can increase our production to one gun factory with ten doors a day, and four gun factories. We can produce in one month. Twelve hundred cannons," Sebastian said.

Zhang Qiang also began to get excited, [-] cannons, think about it, if there are [-] cannons on the battlefield and placed in front of the enemy's position at the same time, then the enemy's face, you don't have to think, you can know what it looks like .

"Hahaha, that's great. I decided that in addition to half a month for the development of the iron mold gun method, the second half of the month is for trial production. Next month, if you want to complete this idea, in the third month, I will I want [-] cannons, and I will put the cannons all over the border to see who dares to attack me."

Sebastian was excited with Zhang Qiang for a while, then lowered his head and continued to study, "My lord, according to the method of iron mold construction written on the volume you gave, he is not without shortcomings. The yield has been improved, but its quality has not improved much.”

"What do you mean?" Zhang Qiang asked.

Sebastian said: "The increase in production is because there is no need to wait for the drying time. In the past, it took one to two months for the clay mold to dry, but the iron mold can be reused. With the method of alternate use, we can use it every day. There are the same number of iron molds used, and we can use them repeatedly before the iron molds are worn out, but he can’t solve the problems of range, blast chamber, air holes, and weight.”

Zhang Qiang didn't understand, Sebastian continued to explain: "This method of iron mold construction only increases the output. According to the above, his range is still the same, and the increase is not much. Exploding the chamber, because this method The gun barrel can be tightened inward, so it has improved a bit, at least, it used to be able to fire 150 to [-] developed cannons, but with this method, it can now fire [-] to [-] rounds, which is equivalent to a four to five times increase.”

"Well, that's pretty cool. Cannons of this quality probably haven't even been made in the West."

Zhang Qiang erased the time of appearance in the records on the parchment, that was around [-], and now it is [-]. It can be said that as long as he follows the method on this parchment, he can make a cannon, even if there is no scientific basis, Se Bastian does not have as much theoretical foundation and knowledge as those later Western scientists, and he can also use [-]% to [-]% of the ability of the parchment.

"Okay, I know, develop it right away, wait for it to be built, and if it is successful, then build a large number of cannons. With these cannons, my territory is solid, and anyone who wants to hit me has to weigh it."

Zhang Qiang is not afraid of the Qing army coming, but his opponent is not the Qing army with little technological content, but the future Portuguese and Dutch. This is the next opponent he chooses. Opponents, do you still need to be afraid of them?

Zhang Qiang has plenty of means to deal with them.

Chapter 164 Iron mold building gun method [-]

Sebastian took Zhang Qiangtong's system transaction to the Iron Model Cannon-Building Method parchment to study for half a month, and finally made a breakthrough at the end of the month.

Sebastian sent someone to report to Zhang Qiang, and Zhang Qiang rushed to the artillery factory in the mountains of Jinhua Prefecture without stopping, and was led directly to the shooting range of the artillery factory.

But when he saw that it was still a bronze shell, he couldn't help but frowned.

Sebastian quickly explained: "My lord, just to be on the safe side, I still used bronze as a raw material to experiment with your iron mold cannon-building method to cast cannons.

Although this is a bronze cannon body, the iron mold is forged with refined iron. After some experiments, the results are remarkable.

In the case of sufficient raw materials, under the operation of skilled workers, five iron molds were forged in one day, 35 iron molds were forged in only six days, and thirty bronze cannons were cast in two days. After testing, each gun can fire a two-pound shell 250 times with a half-pound charge.

This is better than the artillery captured by the Ming and Qing armies, each of which can fire 120 to 150 shells, and even the bronze cannons cast by officials, which can fire 180 to 210 shells. At least ten to twenty percent of the number of shells. "

Hearing Sebastian's words, Zhang Qiang was not happy. Nima, you told me that you could launch [-] to [-] rounds. Why did you tell me now that you have improved me by [-]%? To the quality of fifteen, there is still a long way to go from what I said at the beginning, and what I thought.

"Why is this happening?" Zhang Qiang asked angrily.

Sebastian said calmly, "My lord, listen to me, the progress of technology must be slow, we can't become fat in one go, can we?"

Zhang Qiang looked at him, and Sebastian looked calm.

Zhang Qiang had countless thoughts in his heart. Now he really has no choice. Now Da Ming rejects science. Yes, in the current period of war, in this era where transportation is basically based on walking and communication is basically based on shouting, it is still very troublesome for him to find those historical heroes. He may not even try to find them for a year or a half. People work hard for you.

In the final analysis, loyalty is not enough.

Thinking of loyalty, Zhang Qiang looked at Sebastian, yes, he is a Spaniard, he came here with the Dutch, the Dutch and the Spaniards are almost from the same country.

Europe is a Ming Dynasty with countless princes, but they have not experienced the feudal dynasty period, and directly entered the capitalist period. The biggest role of the feudal dynasty period is the great unification, which is the period of national integration. The civilization of the Ming Dynasty for 5000 years can bring countless The nationalities merged to form a unified dynasty.

This has both advantages and disadvantages. There are many advantages. A country, a nation, is powerful, can communicate with each other, exchange what is needed, and increase the economy and population. The disadvantage is that the hearts of the people are inconsistent and the beliefs are disordered. There is always something called religion in Europe. Put people's hearts together, with one heart, you can form a gang with one belief at any time, and find someone to PK to fight in a group. If you want to fight in a group in China, it is estimated that after some conspiracy, one person can PK a group of people. People are not in harmony.

This guy won't delay deliberately just because he sees that he wants to fight the Dutch.

Or maybe he wants to go back to Spain with such technology and make a fortune.

Well, foreigners are mostly greedy for money.

Seeing that Zhang Qiang remained silent for a long time, Sebastian said calmly, "My lord, do you think it's time to start the experiment?"

"Let's get started," Zhang Qiang said calmly.

"Boom boom boom," there was a roar, and the shooting range was confused with gunpowder smoke.

Tried in turn, two-pounders, four-pounders, six-pounders, eight-pounders, twelve-pounders.

The pound is actually a unit of weight, which means that the weight of the shell is different from the diameter of the current cannon. Two pounds is generally equivalent to a [-]mm cannon.

However, it cannot be deduced by analogy, because it will cause a lot of inconvenience. After Zhang Qiang unified the measurement units, he also unified the caliber of the artillery. The two-pound gun is a [-]mm gun. Let these guys use calipers and rulers directly. He copied these from later generations. unit.

Then it was stipulated that the two-pound gun has a caliber of [-] mm, the four-pound gun is actually a [-] mm caliber, the six-pound gun is already a [-] mm caliber, and the eight-pound gun is because Zhang Qiang likes the German [-] mm anti-aircraft gun. Everyone knows, and those who read a lot of time-travel novels know it too, so the eight-pound gun is directly used with a caliber of [-] mm, the ten-pound gun is directly discarded, and the [-]-pound gun is used with a caliber of [-] mm, which is the same caliber as some artillery in later generations.

This Sebastian can make up to twelve-pound guns.

This is not easy. As the caliber and the weight of the artillery shells that need to be fired increase, in the Ming Dynasty, the current artillery still shoots iron balls. The more gunpowder that needs to be loaded, the more gunpowder, the artillery barrel can bear The greater the pressure, the higher the technology required. Sebastian couldn't solve such technical problems, so he could only build such a large-caliber cannon.

Not to mention that the effect is good, the cannon made by this method has actually improved in range.

Because the pressure that can withstand is greater, the amount of charge can be increased, so the iron ball of the same weight will fly farther.

At least the range of each cannon has been increased by 20 meters to 60 meters. Of course, the effective range of the cannons is farther than the actual range. It’s about 300 meters away, because it’s not accurate, no matter how far you fly, it’s useless if you can’t hit the enemy. If you want to hit the enemy, you can only improve the gunner’s technology. As the technology improves, the hit rate also increases.

But if you are bombarding the enemy's castle, city wall, or even a city, you don't need to worry about the hit rate, the farther the better.

The two-pound gun can basically hit 300 meters, the actual range is only more than 100 meters, the four-pound gun is not much more, and 80 meters is more than enough.

The six-pound gun can hit 500 meters away, and can achieve certain results in more than 200 meters to 300 meters.

The eight-pound gun can hit 700 meters, and the twelve-pound gun can hit 1000 to 200 meters.

These are the cannons of the Ming Dynasty, and they were manufactured under Zhang Qiang's auspices. Of course, they cannot be compared with the cannons of the caliber known to the later generations. They are smoothbore cannons for firing those iron balls. Artillery manufactured under the condition that the technology and technology are not good enough.

However, compared with the artillery made by the Ming or Qing army, the number of shells fired, the quality of the barrel, and even the firing range have been greatly improved.

It's just that they still can't meet Zhang Qiang's quality requirements that Zhang Qiang should meet when he exchanged a thousand matchlock guns for the iron model artillery method.

It is even far from this requirement. In the words of the Indian Asan, I paid for the original version. You sold me the monkey version of the weapon. Mr. Russia, are you worthy of the banknotes I gave you?

And Sebastian obviously failed his trust in him.
