By the Feiyu River, Jing Jie is leading a few soldiers to build a new ship.
They still used the old method, first covering one side of the huge log with wet mud, and then using fire to burn the areas that were not covered with wet mud.
Burning it once and shoveling it again, just like this, the cabin is taken out bit by bit. The efficiency is quite low, and the size of the boat depends on the size of the log itself, which is limited to a relatively large one.
When Jiang Xuan came over, he happened to watch them all working hard to light the fire. "Are you building a new ship again? Hello, chief!" Hearing Jiang Xuan's voice, the soldiers also stood up and said hello.
Nepeta also raised his head and said to Jiang Xuan: "Chief, now that our tribe has grown bigger, we often have to transport things across the river. The old boats are not enough, so I want to build a few new boats."
Jiang Xuan nodded and said: "This is a problem. You continue to work and don't worry about me. I will take a look."
"Yes!"
The soldiers saw that the wood was almost burned, so they lifted it aside, turned it over, and used small stone adzes to continuously chip away at the charcoal.
Jiang Xuan looked at it for a while and thought to himself: Building a ship like this is too slow, and the fire is uneven. The ship is thick in some places and thin in others, not strong enough, and not big enough.
The Vine Tribe has now refined bronze, and has figured out the effect of the copper-tin ratio on the hardness and toughness of bronze, so that it can create tools with better performance.
Things like saws, chisels, planes, and even bronze nails can all be made.
In this case, why can't we use more advanced shipbuilding methods to build better and larger ships?
Jiang Xuan stood on the bank of the river, watching the soldiers of the fishing team busy while thinking about these issues. After standing for a while, he made a decision. "Leader Jing Jie, come here with me. I have something to talk to you about."
Say."
Hearing Jiang Xuan's words, Jingjie stood up in a hurry and followed Jiang Xuan to the deserted river beach in front of him. "Chief..."
Jingjie was very worried. He didn't know what Jiang Xuan was looking for. He thought he had done something wrong and made Jiang Xuan angry.
Jiang Xuan turned his head and glanced at Jingjie. Seeing his cautious look, he felt a little funny and felt an indescribable awkwardness.
The tribe is getting bigger, more populous, and more powerful, but the kindness that the tribesmen used to treat him has faded.
Everyone is in awe of him, even Jing Jie and others, who are no longer as casual in front of him as before.
Sometimes he couldn't figure out whether this was a good thing or a bad thing. Jiang Xuan shook his head and put these thoughts aside for the time being.
"Don't be nervous. I came here to discuss something with you and to hear your opinion. If you have anything to do, chief, just give me your instructions."
Jiang Xuan sat on the big cobblestone and said to Nepeta: "I plan to build a shipyard in the tribe."
"Shipbuilding...factory?"
Jingjie felt a little confused. He knew about shipbuilding. What did this "factory" mean? "You sit down."
Jiang Xuan patted a big pebble next to him. Jing Jie hesitated for a while and then sat on it.
"A shipyard is a place dedicated to shipbuilding. It is not the small ships we use now, but big ships, very big ships!"
"Chief, this is a very big ship. How big is it?"
Jiang Xuan thought for a while and said: "It is more than ten times, even dozens or hundreds of times larger than the ships we have built now!"
Jingjie listened to Jiang Xuan's words, but she couldn't imagine what these ships looked like or how big they were.
"Chief, how big of a tree would it take to build such a big ship?"
In Nepeta's mind, the size of a boat still depends on the size of a tree.
Jiang Xuan smiled and said: "You don't need a very big tree. Ordinary trees can be spliced together to build a big ship!"
"For example, our bamboo raft is made larger by connecting bamboos together, right?"
Jingjie tried hard to imagine, and then said to Jiang Xuan: "What does the leader mean, is that we also use canes to tie the big trees together one by one to make a big ship?"
Jiang Xuan shook his head and said: "If you tie the big trees together, they are called rafts, which are the same as bamboo rafts. They are not called boats. The big boats we want to build are watertight."
"Let's do this, I'll draw it for you."
Jiang Xuan picked up a branch and slowly drew the shape of a large sailboat on the sand on the river beach.
"Look, this is the big ship we are going to build. It looks like this. The upper part is called a sail, which can use the wind. The lower cabin is very large and can hold a lot of cargo. There are anchors in the front and rear, which can hold The boat is fixed in one place..."
Jiang Xuan pointed to the picture on the sand and explained to Jing Jie about the structure of the large sailing ship.
Nepeta still couldn't imagine what a real sailing ship looked like, but he had a vague impression in his mind.
"Of course, our Vine Tribe cannot yet build such a large ship, but it doesn't matter. We can start from small sailboats and accumulate experience bit by bit."
"As long as we have the first batch of real boats, whether you are fishing along the river, transporting people, or transporting things across the river, it will be much more convenient than before."
After listening to Jiang Xuan's words, Jingjie struggled for a while and asked: "Chief, how can we build such a big ship?"
Jiang Xuan laughed and said: "Such a big ship cannot rely on fire to burn wood or those few stone adzes. We need new tools, tools that are more useful and convenient than stone adzes!"
"Then where are we going to find new tools?" Jing Jie felt that her brain was not enough.
"Don't worry, our tribe will soon make a batch of new tools, which can be used in the shipyard first. It will definitely open your eyes."
"However, these new tools are the secrets of the tribe and must not be known to too many people."
"So, you have to select a few warriors with the most experience in shipbuilding and the toughest words in your fishing team, and I will select some people from other places to be responsible for shipbuilding."
This chapter is not over yet, please click on the next page to continue reading!
Jingjie nodded hurriedly and said, "Okay, leader, I'll pick someone up right now."
Jiang Xuan hurriedly grabbed him and said: "Don't rush, don't rush, the new tools haven't been made yet, you take your time and choose."
Jing Jie then sat down again and listened to Jiang Xuan continue to talk about the shipyard and the fleet that might be formed in the future.
Jiang Xuan told him that the world is not only filled with small rivers like Feiyu River, but also raging rivers, and even vast oceans.
If the Vine Tribe can build a huge fleet, it can travel to very far places along these waters, obtain a large amount of resources, and help the tribe develop...
Jingjie felt his heart surge as he listened to the scenes described by Jiang Xuan, and a seed of sailing on a long voyage was quietly planted in his heart.
Jiang Xuan went into the smelting workshop again and began to make various shipbuilding tools.
He first used the lost wax method to create a large number of pottery models, hammers of various sizes, saws of various lengths, chisels of various types, planes for planing boards, bronze nails, and even small anchors...
Finally, he even made several pottery models of scissors and kitchen knives, which were used by himself and Chi Shao.
If the Vine Tribe becomes strong enough in the future and is not afraid of the exposure of bronze weapons, he hopes that everyone in the Vine Tribe can use such convenient and fast daily tools as bronze scissors and kitchen knives.
Then, he began to think about the copper-tin ratio of various tools.
In order to make a bronze dagger, he had done a lot of experiments before. He had recorded what kind of copper-tin ratio and what kind of effect it could produce.
Therefore, when making tools this time, he was not as blind as before. At least the tools he made were definitely useful, no matter whether they were good or not.
For example, a saw is specially used to cut wood. It does not need to be very tough, it only needs to be hard enough to ensure that it is sharp enough.
Therefore, the ratio of copper and tin used by Jiang Xuan on the saw is five parts copper and one part tin.
When he was making tools, Jiang Xuan also ordered an artificial lake to be dug and a house to be built in his second residence by the river far away from the crowd, and he even surrounded that area with a wall.
With the artificial lake, after the ship is built, it can be directly launched into the water for inspection. If the ship is relatively large, it can also be driven directly into the river through the artificial lake.
More than half a month later, various shipbuilding tools were built one after another, the artificial lake was excavated, and river water was introduced.
A long wall surrounds the artificial lake and a wide riverside beach.
A part of the soldiers from the second guard team were specially assigned to guard this place, and no unrelated personnel were allowed to approach.
Jiang Xuan summoned three apprentices from the stone tool workshop who were talented in carpentry, plus three warriors from the fishing team who were good at shipbuilding, a total of six people, who became the first batch of personnel in the shipyard.
On the fifth day of June, the Tengzu Shipyard officially started construction.
On the day when the construction started, only Jiang Xuan, Red Peony, Uncaria, Stone Loach, Nan Xing Jie, and six selected people attended.
Next to the artificial lake, there is a large open space. Several tall houses have been built on both sides of the open space, all of which are mud brick houses.
Jiang Xuan stood in the open space, with Chi Shao and others behind him, and the six shipyard employees in front of him. Jiang Xuan began to speak.
"Today is the day when our Vine Tribe Shipyard starts construction. It should be lively, but in order to keep it secret, other people cannot come over."
"Can anyone tell me what the purpose of building a ship is?"
A soldier thought for a while and said: "To fish, to cross the river."
Jiang Xuan smiled and said: "Yes, you are right, but do you know how big the largest fish is and how wide is the widest river?"
The soldiers looked at each other and then shook their heads.
Jiang Xuan pointed to the Feiyu River and said: "This river in our Teng tribe is a small river. The small river flows downwards and gathers with other small rivers to become a big river. If the big river continues to gather other water flows, it will become a big river.
It's getting bigger and bigger, so big that you can't even imagine it."
"Let's put it this way, if you try to rock the boat from one side of the river to the other, you may not be able to do it in half a day. You may even be swept away by the big waves and capsize the boat."
"Is the big river the largest body of water? No, there are many, many big rivers that flow into the sea. The sea is countless times larger than our entire Southern Wilderness, and there are really big fish living in it."
"How big is the big fish? It's as big as a mountain. If it swims to us, Feiyu River won't be able to hold it."
Jiang Xuan's description stunned the six warriors. Their knowledge was limited to their imagination, making it impossible for them to imagine what the big rivers and seas were like.
How much does a fish as big as a mountain have to eat every day?
Even Chi Shao and the others behind Jiang Xuan were shocked and speechless.
They have no doubt about Jiang Xuan's words, because Jiang Xuan has created so many things that they have never seen or heard of.
They were in a remote corner of the Southern Wilderness. What they thought about most before was how to survive, and what they thought about most was to establish a larger tribe.
But now, Jiang Xuan's words have opened their eyes, letting them know that there is a wider world outside the mountains, and many things they cannot imagine.
"So, the purpose of our boat building is not only to fish and cross the river, but also to explore a wider and more exciting world!"
"Of course, it's a bit early to say this now."
"Our shipyard has just started construction. The goal at this stage is to build the first real boat out of wooden boards instead of a canoe made of fire."
"In order to build a small boat, the soldiers in the smelting workshop and I made a batch of tools. These tools are the first to be used by the entire tribe and the shipyard, so they must be kept secret."
Jiang Xuan's eyes became sharp: "If someone leaks the information about the tools, not only will the leaker die, but the relatives around him will also be implicated."
Jiang Xuan's words made the six warriors feel a chill in their hearts. Even Undou and the others felt the pressure. "Of course, you work for the tribe, and the tribe will never treat you badly."
"As long as a new ship can be built, everyone will receive a very generous reward."
"Okay, I've said all that needs to be said. I announce that the shipyard has officially started!" After Jiang Xuan finished speaking, he led everyone into the newly built house and showed them brand new bronze tools and these tools.
Usage.
"This is called a saw. It can cut wood easily, and it can also saw wood into wooden boards. Just watch!"
Jiang Xuan picked up a bronze hand saw, walked to a piece of wood, put the saw on it, and pulled it at a constant speed.
"When sawing wood, your hand should be steady and the saw should not be biased, otherwise it will get caught easily."
As Jiang Xuan continued to cut down, the bronze hand saw quickly sank into the wood, and wood chips flew into the air.
"Boom!"
Before long, the wood was sawed into two pieces and rolled several times on the ground.
Everyone around Jiang Xuan's eyes lit up, this tool is so useful.
You know, in the past, if they wanted to break wood, they could only use stone axes to chop it bit by bit, and larger wood had to be burned by fire.
Now, with the saw, you can easily cut the wood, and the speed has increased countless times.
"This is an axe. You should be familiar with it. However, this bronze ax is much sharper than a stone axe."
Jiang Xuan picked up a bronze ax again and struck the wood with the axe. The ax blade sank deeply into the wood.
Afterwards, Jiang Xuan kept swinging the ax, and soon he cut a flat surface on the wood.
Those soldiers became even more excited. If the stone ax was to be cut like this, it would take at least a long time to cut it.
Jiang Xuan picked up another bronze plane and said, "This tool can make the wood smoother. Just watch."
Jiang Xuan laid the wood flat on the ground, then held both ends of the bronze plane with both hands. He pushed it gently, and a thin shaving appeared.
As he continued to push, the surface of the wood quickly became smooth, with no burrs visible...
"This is called a chisel..."
Jiang Xuanyang showed them these bronze tools and explained their usage in detail.
Everyone present looked at these golden tools and felt as if they were in a dream, feeling dizzy.
