"Xianggong, this is Ling Zhen. The pen "Fun" Pavilion www.biquge.info "Zheng Zhicai went to the back hall of the yamen, and Yang Zhi stepped forward to introduce. This errand in Tokyo was really time-consuming and laborious, and it was finally time to make the errand, which showed the eagerness in Yang Zhi's heart.

Zheng Zhi looked at the person next to Yang Zhi, his appearance was extremely ordinary, his figure did not look very tall, his skin was dark, he did not look strong, his beard was unkempt, his hands were calloused, and he really looked like a craftsman.

"Little Ling Zhen, meet Xianggong." Ling Zhen immediately stepped forward to pay his respects.

Zheng Zhi was very happy in his heart, as long as Ling Zhen came, many things would be easy to say, and said with a smile: "Sit down first." ”

Zheng Zhi walked to a chair in the middle and sat down, and then said, "Ling Zhen, I heard that you are good at gunpowder, and you are also a good at making cannons?" ”

"Returning to the father-in-law, the little one knows this way." Ling Zhen faced Zheng Zhi, obviously there was a kind of respect in his heart, which was also a habit in the bones of people in this era.

"Okay, it's good to understand, tomorrow I will personally run a pretentious yamen for you, you are responsible, I will tell you some things, if you do it, you will be rewarded." Zheng Zhi said again, his tone was a little excited, if this matter is successful, I don't know how many brothers under his command will die in the battle array. It's all a living human life.

Ling Zhen was also delighted when he heard this, when Yang Zhi persuaded Ling Zhen to come to Cangzhou in Tokyo, he had already given a large amount of money, and naturally spent a lot of tongues, but no matter how much Yang Zhi spoke, it was not as good as Zheng Zhi's promise to be a little fair in Cangzhou.

"The prime minister commands, and the small one must be properly handled by the prime minister." Ling Zhen obviously guessed what was going on, and he also had this confidence in his heart.

Of course, Ling Zhen guessed well, that is, to build artillery, so he was very confident. But Ling Zhen also guessed a little less, that is, the cannon that Zheng Zhi wanted to build was not the cannon that Ling Zhen would build at this time, and the two cannons were not the same thing at all.

From the improvement of the composition and power of gunpowder, to the caliber and size of the cannon, there is a world of difference. What Zheng Zhi wants to build is a real artillery, not a cannon used for posture in this era. In Zheng Zhi's view, the gap between the scientific and technological level of the two is not large, but there is a world of difference in thinking and technology.

In this era, no one really thinks about gunpowder as a real weapon, and gunpowder is at most a dispensable auxiliary means in the military of this era.

"The cannon I am going to build is different from yours, a cannon with a bowl of iron, a cannon that can shoot iron balls for miles, a cannon that pierces the gates of the city, and smashes the walls." Zheng Zhi looked at Ling Zhen and said.

When Ling Zhen heard this, his face changed, and his eyes widened and asked, "Xianggong, this... ”

Zheng Zhi also knew that Ling Zhen had his own opinions, and said straightly: "If you have something to say, you don't need to be polite." ”

"Okay, the small one will be straightforward, Xianggong's idea, when I was in Tokyo, the small one also thought about it, but it is difficult to realize, once the muzzle is large, it is inevitable to increase the thickness and length of the gun body, and the cost is amazing. Second, even if the gunpowder is built, the power of the gunpowder may not meet the requirements of the fair, and it is extremely troublesome to clean up. And then such a huge iron tool, it is really troublesome to carry, and the march is a huge problem, which can only be left in one place and does not make much sense. Why don't you think about it? Ling Zhen replied.

Ling Zhen is not unreasonable, if according to the ideas of the people of this era, a few hundred catties of iron to build a big guy like this, it is better to build countless blades and equip more troops. At the level of land transportation in this era, these hundreds of catties of iron are a burden everywhere.

Zheng Zhi knows the power of it deeply, and his thinking is comparable to Ling Zhen. As long as the propellant is improved, the cannon can hit farther and damage more effectively. Solid shells are full of power, not to mention that explosive shells can be developed in the future, which is a big killer on the battlefield.

There are many cannons with one or two guns, if there are only a few, the meaning is really not much, if there are dozens or hundreds, it is completely different, attacking the city and grabbing the land, invincible.

As for transportation, in people's established thinking, such a heavy object is absolutely inconvenient to transport, and it is really like a cumbersome burden for logistics. Zheng Zhi knows that manpower is infinite, as long as there is enough manpower, there are cars and horses, and humans can carry cannons anywhere.

"That's fine, the only thing you have to solve is how to develop the procedures and specifications for making cannons and improve the power of gunpowder. You don't have to worry about the rest, I'm going to build a hundred of these cannons. When it comes to gunpowder, I'll give you a matching number, and then you can test it yourself, nine times out of ten. "Where does Zheng Zhi care about Ling Zhen's established ideas, if a hundred cannons are really built, Zheng Zhi can wake up laughing in his dreams.

Ling Zhen didn't hear anything else, but he heard Zheng Zhi's gunpowder ratio number, and hurriedly asked, "Xianggong, do you have a better gunpowder ratio?" ”

Zheng Zhi nodded, looked at Ling Zhen, and said in a sharp tone: "The number naturally exists, but you must not pass it on to anyone, as long as you hear this number, from now on I am Zheng Zhi's person, and death is my Zheng Zhi's ghost, you must not have a little second heart, a certain means, you will slowly know." ”

As soon as Zheng Zhi's harsh words came out, the atmosphere changed suddenly, Yang Zhizhi felt a chill around him, and during this time, Yang Zhi slowly learned a lot about Zheng Zhi's affairs. This Zheng Xianggong is not an outsider, if he is angry, he will inevitably be a river of blood.

Yang Zhi suddenly seemed to remember something, got up and gently bowed his hand, and the person walked out of the inner hall. Obviously, Yang Zhi didn't want to hear this secret. Yang Zhi has also been in officialdom for many years, and has also done things under Gao Yu for many years, at this moment, it is better not to know than to know. If Luda was here, he would definitely not avoid it like Yang Zhi.

But when Ling Zhen heard this, he didn't feel a trace of threat at all, it wasn't that Ling Zhen wasn't afraid of death or anything like that, it was really Ling Zhen who cared too much about this ratio number, and he was all about this matter, which was where the spirit of craftsmanship lies.

"Xianggong, since I, Ling Zhen, have arrived in Cangzhou, I have never thought about having two hearts, Xianggong said quickly." Ling Zhen asked eagerly.

"One nitrate, two sulfur and three carbons." Zheng Zhi said that he knew better in his heart that the relationship between these three numbers was not really a one-to-two relationship.

"Xianggong is talking about a pound of fire salt, two taels of sulfur, and three taels of charcoal?" Ling Zhen was shocked, Ling Zhen only heard this sentence, and he also believed in his heart that this thing was true.

is Ling Zhen's sentence, Zheng Zhi also knows that Ling Zhen is really an expert talent, not blown out.

"Exactly. This matter is in your ears, and no third person is allowed to know about it. Zheng Zhi said. The truly scientific ratio of black powder was not really obtained until the Ming Dynasty after countless tests, and it was also clearly recorded by Qi Jiguang in the military book.

A pound of nitrate, is 16 taels of nitrate, 2 taels of sulfur, 3 taels of charcoal, that is, 76.19%, 9.52%, 14.29%, has been the closest to the ratio determined by modern science, the data of modern scientific determination is 75%, 10%, 15%. It is already the most scientific gunpowder ratio.

Ling Zhen immediately showed joy and replied: "Xianggong, the little one will try, try it tonight, and invite Xianggong to come and see tomorrow." ”

Zheng Zhi didn't reply, but just shouted loudly: "Yang Zhi, come in." ”

At this time, Yang Zhi entered the room to salute and stood in front of Zheng Zhi to wait for Zheng Zhi's instructions.

"You take Ling Zhen to see Pei Xuan, let Pei Xuan arrange some craftsmen to help Ling Zhen, and then take Ling Zhen to the camp outside the city, and Shi Jin will be responsible for guarding, but if Ling Zhen needs to buy any items, you will do it with him as soon as possible." Zheng Zhi arranged, and he was also a little careful in his heart, this matter was too important, and only when Shi came in to guard could he feel at ease.

Zheng Zhi also thought that he would also go to the camp tomorrow to personally arrange the area of the test, the work of the guards, and the issue of confidentiality.

"Obey military orders!" Yang Zhi didn't know where the matter was important at this time, and he didn't dare to be the slightest bit lazy.

Ling Zhen's heart was full of this gunpowder ratio, he got up and gave up his hand, and walked out, and asked Yang Zhi to quickly lead the way, just wanting to immediately test the ratio of this gunpowder, whether it was as powerful as Zheng Zhi said.
