Zhang Guoan's original Yalang in Lin'an City also took the initiative to come to the door to serve, for no other reason, the labor cost they gave was high. Pen % fun % Pavilion www.biquge.info

Zhang Guoan asked him to run errands to see if he could buy a private shipyard, and it was especially important to pay attention to the fact that there must be master craftsmen.

The tooth man went happily, and he was paid a lot for such a big job.

He knew where to look for it, and ran directly to the outside of the southeast tide gate.

During the Northern Song Dynasty, Mizhou, Shandong Province, was the city of the world, and it was also a shipbuilding place of the Great Song Dynasty.

As early as 1083, the king of Goryeo died.

Obituary, Song Shenzong sent Yang Jingluo and Wang Shunfeng to pay tribute, Qian Xian, Song Qiu condolence, and at the same time, Song Shenzong also ordered people to build a few envoy ships in the official ship yard of Mizhou.

At that time, there were still many shipwrights who relied on the timber resources of the local mountains and forests to engage in private shipbuilding and ship repair, and the ships built by the official shipyard were only for the use of the local navy and the government, and most of them were small and medium-sized simple sea ships and inland channel ships.

On the contrary, the ships built by the private shipyards are of higher quality, often building large sea ships more than ten zhang long, with a depth of up to three zhang, and the cabins are often three floors, which can carry 400 people, and the supplies they carry can be used for a year.

They often use pineapple wood from the local mountains as keel wood to make the ship stronger.

However, all this disappeared with the invasion of the Jin.

At that time, many shipyards were relocated to the south, and some of them moved outside Lin'an.

They have been slowly integrating into local life for more than 100 years, but in the shipbuilding industry, they cannot compete with the local shipbuilding industry, and they are all reduced to repairing ships.

They now have a permanent residence outside the city of Houchaomen.

That Yalang was confident that he could recruit a suitable shipwright and even buy a shipyard.

This matter is very important, Zhang Guoan originally wanted to go with that Yalang, but the commander of the arquebus battalion in front of the Imperial Arquebus, Fa Ke, came again, and this time he came with a few bags of fruits.

Zhang Guoan looked at those fruits and wanted to laugh. Did this kid take the price as a gift? And just send this?

However, this is also a change for a phoenix man.

The commander of the Imperial Arquebus Battalion, Fa Ke, said with sparkling eyes: "Zhang Dashang, the nitrate and sulfur you sent are extremely easy to use, and the medicinal power is full!" ”

Zhang Guoan said lightly: "Have you guided your official family to design an eight-stage round shooting method?" ”

The commander of the Imperial Arquebus Battalion, Fa Ke, said with sparkling eyes: "The medicinal power of that black fire/medicine can actually increase the range by two percent!" ”

Zhang Guoan said lightly: "Don't you usually go to Pingzhang Jia Nidao to report on your work?" ”

“------”

The imperial commander Fa Ke found that his thoughts and Zhang Guoan's business were on two roads and did not match.

Zhang Guoan said lightly: "You answer my question first------"

The commander of the arquebus battalion in front of the Imperial Arquebus, Fa Ke, said: "A certain person has guided with his heart, but the official family has not said it; A full-day training arquebus battalion. I care about the ordnance station, and I don't have time to report ------"

Zhang Guoan said lightly: "Then why do you have time to come to me?" ”

"------ for the sake of black fire/medicine."

"Then please remember that it is not what you do now, but what the leader thinks is the most important; It doesn't matter what you do, it's what the leader thinks you can accomplish is the most important! ”

"Leader--- guide?"

"I said it wrong, it's Pingzhang------ you see, why did Jia Pingzhang handle the grain planting matter in Huangzhuang these days, making such a fuss?"

"Good seeds, the world is full!"

Zhang Guoan was speechless for a while. He is really similar to the young people in that world, lacking the ability to see the essence through phenomena.

Zhang Guoan said: "This is called highlighting the official family------ highlighting the official family is to highlight yourself, because this is the place of the Zhao family." Let me ask again at the end, how will you guide the official family to explain the method of eight-stage round shooting? ”

"------ will."

Zhang Guoan is satisfied, this is a smart young man.

"You don't have to say anything more about the black fire/medicine, in the future, I will provide you with nitrate and sulfur regularly."

"I heard that there is a sulfur mine in the northern part of Oshima ------ Ryugu-------"

"What? Do you want to open a mine? I can allow you to go up to my island and mine! ”

The commander of the Imperial Arquebus Battalion, Fa Ke, laughed and said, "I heard that an official suggested going to the ------ mine."

"Yes. It is enough to share with me, and brimstone is not a forbidden thing for you. ”

The Great Song Dynasty stipulated that ten kinds of goods were forbidden. That is, tortoiseshell, ivory, rhino horn, biniron, leather, coral, agate, frankincense, purple ore, brass, all purchased by the market.

The commander of the Imperial Arquebus Battalion made Fa Ke think about it in his heart, divided into you? I'm afraid it won't be that simple------ but he won't say it.

When he came back this time, Zhang Guoan also had a purpose, that is, he wanted to take out the return cannon to the Great Song Dynasty.

In the battle of Xiangfan City, the Great Song Dynasty mainly lost on the weapon of Huihui artillery.

It is recorded in the later "Yuan History": "Ten years. From the national army to attack Xiangyang did not go down, Yisima because of the topography, placed the cannon in the southeast corner of the city, weighed 150 pounds, and the machine was fired. The sonic shook the heavens and the earth, and all the blows were destroyed, and they fell into the ground seven feet. Song appeased Lu Wenhuan's fear and surrendered to the city. ”

Zhang Guoan had seen the so-called return cannon drawings before, which was just a large-scale balanced counterweight stone thrower, and this kind of stone thrower was just an improvement, improvement, and innovation on the basis of the ancient stone thrower, making it more advanced and more powerful.

But for the Great Song Dynasty, which is not developed in mathematics and physics, this thing can be regarded as a superweapon in this time and space.

If history does not change, in 1274, the most critical year, the Tatar army crossed the river, and the Song soldiers Chen on the south bank of the river, supporting the boat division to meet the battle.

Buber, the son of Yismain, shelled it back on the north bank, and Song Zhou sank completely.

Therefore, when Zhang Guoan did not completely solve the problem of artillery, he first gave this to the Great Song Dynasty.

It can shoot 150 kilograms of cobblestone and has a range of 400 meters.

Zhang Guoan first demonstrated with a pencil on the table and talked about the principle of the lever------ this kid is smart and quickly understood the truth.

However, his sparkling eyes were strange, why did he talk about it?

Zhang Guoan said: "Next, I'll show you the stone cannon I designed, what about you, I'll go to Jia Pingzhang's house in a while, dedicate this picture to him, just say that you came up with it, and ask him for guidance."

Why, you don't want to? ”

The commander of the Imperial Arquebus Battalion, Fa Ke, glared at the sparkling eyes and said, "Why are you lying? ”

Zhang Guoan thought to himself, I want you to be promoted quickly------ but, he said: "It's not a lie, it's to make it play its best role, you can't do it alone, look at the picture!" ”

He looked at it seriously, and suddenly asked again: "Zhang Dashang, how much weight can the counterweight you write there?" ”

Zhang Guoan said according to the weight unit of this time and space: "Ten stones! ”

He said, "It should be so heavy!" ------How many gunners do you have to match this-------"

Zhang Guoan said: "This is the second question------ let's talk about the problem of fixed pulleys." (To be continued.) )
