Keep it secret. Once people from other tribes know that the main components of the copper plow shovel are copper and tin, it will be relatively easier to further study the copper-tin ratio.
Even the people of other tribes didn't know what tin was. Only the time traveler Ma Yue knew the significance of copper-tin alloys. From soft red copper to the emergence of alloy bronze, human history has gone through thousands of years of development. How could it be so easy to understand?
You don’t even have the most basic concept of alloys, how can you study proportion problems?
Copper-tin alloy is the greatest technological secret of the Hai Tribe, but the technicians who know this secret are all ensconced in Haifan City. Qiu Haicheng's copperware workshop is only a rudimentary forging of copper ingots. Even if you capture those forging copper ingots, they don't know what tin is.
Why does it have to be a copper-tin alloy? It's so simple. The copper mines in Qiu Haicheng have the highest proportion of semi-cooked tin ore, which makes it easier to collect raw materials. Besides, a simple copper-tin alloy is easy to find and adapt to by coppersmiths. Adding an element like lead would require re-researching the combination ratio, further increasing the difficulty for workers to forge copperware.
There is no need to make it so complicated. Just use whatever raw materials are available. The most important thing is to make it suitable for large-scale production.
The current copper-tin alloy bronzes have sufficient hardness and toughness to be suitable for use as copper plowshares.
The management of Haifan City is very strict. Even the caravans passing through Haifan City are accompanied by rotating chief and deputy soldiers. It is very difficult for you to infiltrate Haifan City as a spy to spy on the internal secrets of Haifan City.
What's more, the copper workshop's production is all in the tool city, which is more secretive.
The Hai Tribe's copper plowshares are used. If you damage one, you must return the old one before you can get a new one. Can you also take the damaged copper plowshare back to the copper workshop for reprocessing and reuse? Waste is shameful, especially when it comes to precious copper plowshares.
The management mechanism of the Haibu Migrant Department is very sound, and Ma Yue is not worried about this.
"You charlatan, it's still difficult to transport coal to the southern branch in winter." said the third priest.
"It doesn't matter. The South Branch doesn't have any manufacturing industry. It just uses coal for daily life. It's no big deal to waste some transportation capacity." Ma Yue said. The population of the South Branch is increasing, and the fuel problem has always been transported from the frozen area of the North Branch by ice and snow vehicles in winter.
It's really a huge waste of transport capacity.
Besides, the Southern Branch doesn’t lack manpower and transportation capacity, right?
"What's wrong? The coal reserves of the Northern Branch are also insufficient?" Ma Yue asked.
"Bing Yueyue once had a report on the coal reserves of the northern branch. The coal seams there are relatively shallow, so there won't be any major problems in the next few years." The second priest said that the spiritual exploration of the cultivators is generally accurate.
"In recent years?" Ma Yue frowned.
"Yes, we are worried that the coal in the northern branch will be like the copper mine in Qiu Haicheng. What will we do if it is gone? The salt boiling, pottery making, copper making, etc. in our Haifan City are becoming more and more dependent on coal." The third priest was worried.
As the population of the sea tribe grows, the demand for coal becomes greater and greater. Coal is needed for everything.
"Originally, in the copper plow shovel transaction between us and the ghost town, the other party gave us coal. However, this time the ratio became three to one, and they didn't even give us coal." The third priest continued.
“Where’s the coal in the ghost town?”
"Our information is that most of the coal produced in the Ghost Town Coal Mine has been seized by the grassland people." Chunwu said, "The charlatan, the salt lake in the East China Sea Island is boiling salt and burning coal."
Oh, yes, the Hai Tribe uses coal to make salt, so of course they use coal to make salt. Since coal is a good tool for making salt, why should it be given to you in the Hai Tribe?
In reality, the Sea Tribe's salt production was also enormous, consuming even more coal. Fortunately, there was coal in the large forests near the Sun City and Poseidon City branches; there was coal in the North Branch; and Lingguo Island had more shrubs, so they could burn firewood nearby, so they didn't even need coal.
With a large population, there are many things to worry about. The copper mines are almost gone, and the coal in the northern branch will only last a few years...
"I remember Qiu Haicheng also has coal."
"It's not within the sphere of influence of Qiu Haicheng. I heard that the production is not large either. All of it is sent by the surrounding tribes."
"It is said?" Ma Yue frowned, "Didn't Tielin go to the Qiu Haicheng coal mine?"
"No!"
I guess Tielin was only thinking about the copper mine and not the coal mine.
Most of Qiuhai City's coal was shipped by the North Branch via Haifan City. This had always been the case, and everyone was used to it. Later, because most of the copper workshops moved to Haifan City, the amount of coal shipped to Qiuhai City decreased significantly.
"I'll go over and take a look." The Bing Yueyue sisters were not there, Tie Lin was in Sun City, and the remaining Tie Chun's cultivation was still low, so Ma Yue had to go himself.
I don’t know if Wangcai doesn’t like the spirit horse anymore. For a long time, Wangcai hasn’t followed the spirit horse around and has always stayed away from it.
This time when we go to Qiu Haicheng, Wangcai will of course follow. Ma Yue’s fire spirit boat is big, so a hundred-man guard team will also follow.
Whoosh, whoosh, after a few hours of sea travel, Ma Yue arrived at the beach of Qiu Hai City. The speed of the fire spirit boat was too fast.
"Charlatan!" There was only one leader left on Qiu Haicheng's side, Yang Hu. There were about seven or eight hundred regular and deputy soldiers of the Hai tribe in the city, most of whom were working. There were only about a hundred regular soldiers in rotation training in the city.
Not bad. Even though Qiu Haicheng's status is declining, he can still produce and live normally. Isn't that good? Although the output of copper ore is getting lower and lower, there is still output after all, right?
"Can we still raise pigs here?"
"Yes, the climate is cold, but pig grass can still grow. Although the pigs here are not very fat, they are at least 130 to 150 kilograms, so it's not a waste of food." Yang Hu said.
"That's good, at least it produces more meat than sheep." Of course, pigs cannot just eat pig grass. The Hai tribe has a relatively large output of sweet potatoes and potatoes, so it's appropriate to feed the pigs some of them. Haifan City is like that.
The pigs in Qiu Haicheng eat fewer sweet potatoes and potatoes, so they're naturally not fat. Does having something good mean it's good?
Sheep are difficult to raise and require a large area of grassland.
"Is the harvest from the fields small?"
"Last year was very cold, so we didn't start planting until May. The potatoes that grew were pitifully small, and the annual yield per mu was only 300 kilograms. It was impossible to grow two crops of potatoes."
"That's fine, 300 kilograms is good." Ma Yue didn't mind the small amount at all. There weren't many people from the Sea Tribe in Qiuhai City anyway. Compared to the even more miserable Poseidon City and Sun City, there was almost no food produced there.
Of course, while Qiu Haicheng had a decent yield per acre, the mines were packed with people. You couldn't deny the miners food, could you? You'd have to trade food for the coal sent from the surrounding areas. Therefore, Qiu Haicheng still needed food aid from Haifan City.
The beach at Qiu Haicheng's outlet to the sea is too small, and the salt output is not much. It is good enough for Qiu Haicheng to use himself.
As the chief of Qiu Haicheng's branch, Yang Hu was also worried that if things continued like this, Qiu Haicheng would really go bankrupt.
