By the Feiyu River, Nepeta is building a new boat with a few soldiers.

They still followed the old method of covering one side of the huge log with wet mud, and then used fire to burn the areas that were not covered by the 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, and the limit is relatively large.

When Jiang Xuan came over, he happened to watch them all working hard to burn the fire.

"Are you making a new ship again?"

"Good leader!"

Hearing Jiang Xuan's voice, the soldiers also stood up to say hello.

Jing Ji also raised his head and said to Jiang Xuan, "Leader, now that our tribe has grown bigger, we often have to transport things across the river, and 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 keep busy, don't worry about me, I'll take a look."

"Yes!"

When the soldiers saw that the wood was almost burnt, they carried it aside, turned it over, and continued to chisel the charcoal with small adzes.

Jiang Xuan looked at it for a while, and thought to himself: The speed of building a ship like this is too slow, and the fire is not evenly burned. The built ship is thick in some places, thin in some places, not strong enough, and not big enough.

The rattan tribe has now made bronze, and has explored the effect of copper-tin ratio on the hardness and toughness of bronze, and can make tools with relatively good performance.

Things like saws, chisels, planes, and even bronze nails can be made.

That being the case, why can't more advanced shipbuilding methods be used to make better, bigger ships?

Standing on the bank of the river, Jiang Xuan thought about these questions while watching the soldiers of the fishing team busy.

After standing for a while, he made a decision.

"Leader Nepeta, come with me, I have something to tell you."

Hearing Jiang Xuan's words, Jing Ji hurriedly got up and followed Jiang Xuan to the beach with no one in front.

"leader"

Jing Ji was very uneasy in his heart. He didn't know what Jiang Xuan was looking for him, and he thought it was because he didn't do well, which made Jiang Xuan angry.

Jiang Xuan turned his head and glanced at Jing Ji. Seeing his cautious appearance, he felt a little funny, and also had an indescribable feeling of awkwardness.

The tribe is getting bigger and bigger, the population is getting bigger and bigger, and the strength is getting stronger and stronger, but the intimacy that the tribes people treated him in the past has changed.

Everyone is in awe of him, even Jing Ji and others are no longer as casual in front of him as before.

Sometimes he can't figure out whether this is 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 to you to discuss something with you and to hear your opinion."

"If the leader has something to do, just tell me."

Jiang Xuan sat on the big pebble and said to Jing Ji, "I plan to build a shipyard in the tribe."

"Shipbuilding... factory?"

Nepeta felt a little stunned. Shipbuilding he knew, what does this "factory" mean?

"You sit."

Jiang Xuan patted a large pebble next to him, Jing Ji hesitated for a while, and then sat on it.

"A shipyard is a place that specializes in building boats. It's not the small boats we use now, but big boats, big boats!"

"Leader, a big ship, how big is it?"

Jiang Xuan thought for a while and said, "It is more than ten times larger than the ships we are making now, even dozens of times, hundreds of times!"

Jingjie listened to Jiang Xuan's words, but she couldn't imagine what these ships were like and how big they were.

"Boss, how big of a tree does it take to build such a big ship?"

In Nepeta's mind, the size of the boat still depends on the size of the tree.

Jiang Xuan said with a smile: "You don't need a big tree. Ordinary trees can be spliced together to make a big boat!"

"For example, our bamboo rafts are connected together with bamboos to grow, right?"

Jing Ji tried hard to imagine, and then said to Jiang Xuan: "What does the leader mean, we also use rattan to tie the trees together one by one to make a big boat?"

Jiang Xuan shook his head and said, "When you tie the big trees together, they are called wooden rafts, which are the same as bamboo rafts. They are not called boats. The big boat we want to build is watertight."

"Well, I'll draw it for you."

Jiang Xuan picked up a branch and slowly drew the appearance of a large sailboat on the sand of the river beach.

"Look, this is the big ship we are going to build. It looks like this. The top is called the sail, which can use the wind. The cabin below is very large, and it can put a lot of cargo in it. The boat is fixed in one place

Jiang Xuan pointed to the picture on the sand and explained to Nepeta about the structure of the galleon.

Nepeta still couldn't imagine what a real galleon would look like, but at least he had an impression of a lake in his mind.

"Of course, we can't make this kind of big boat yet, but it doesn't matter, we can start with a small sailboat and accumulate experience bit by bit."

"As long as we have the first batch of real boats, whether you are fishing along the river, or transporting people, and transporting things across the river, it will be much more convenient than before."

After Jingjie listened to Jiang Xuan's words, she struggled for a while and asked, "Leader, then, how can we build such a big ship?"

Jiang Xuan said with a smile: "For such a big boat, relying on fire to burn wood and relying on those few stone adzes is definitely not acceptable. We need new tools, tools that are more useful and convenient than stone adzes!"

"Then where do we go to find new tools?" Nepeta felt that her brain was not enough.

"Don't worry, our tribe will soon create a batch of new tools, which can be used in the shipyard first, which 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 choose a few soldiers with the most shipbuilding experience and the strictest mouths in your fishing team, and I will go to other places to choose some people who are specially responsible for shipbuilding."

Jing Ji hurriedly nodded and said, "Okay, I'll go pick someone now, leader."

Jiang Xuan hurriedly grabbed him and said, "No rush, no rush, new tools haven't been built yet, you can choose slowly."

Jing Ji sat down again and listened to Jiang Xuan continue to talk about the shipyard and the fleet that may be formed in the future.

Jiang Xuan told him that this world is not only limited to small rivers like the Flying Fish River, but also turbulent rivers, big rivers, and even a vast and boundless sea.

If the Vine tribe can form a huge fleet, they can travel far and far along these waters, obtain a lot of resources, and help the tribe develop...

When Jingjie listened to the pictures Jiang Xuan described, she only felt that her heart was surging. A seed of sailing on a boat was quietly planted in his heart.

Jiang Xuan got into the smelting workshop again and began to manufacture various shipbuilding tools.

He first used the lost wax method to make a large number of pottery vans, hammers of various sizes, saws of various lengths, chisels of various sizes, planers for planing wood, bronze nails, and even small anchors...

Finally, he also made several Tao Fans with scissors and kitchen knives, which were used by himself and Chishao.

If the Veng tribe is strong enough in the future, and they are not afraid of the exposure of bronze ware, he hopes that everyone in the Veng tribe can use such convenient and quick daily tools as bronze scissors and kitchen knives.

Subsequently, he began to ponder the ratio of copper and tin for various tools.

In order to make a bronze short knife before, he has done a lot of experiments. What kind of copper-tin ratio and what kind of effect can be produced, he has a record.

Therefore, when making tools this time, he is not as blind as before, at least the tools made are definitely useful whether they are good or not.

For example, a saw, which is specially used for sawing wood, does not need very good toughness, but only needs enough hardness 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 making tools, Jiang Xuan also ordered to dig an artificial lake in the second residence, away from the crowds, by the river, build houses, and even enclose that place with a wall.

With an artificial lake, after the boat is built, it can be directly launched into the water for testing. If the boat is relatively large, it can also pass through the artificial lake and drive directly into the river.

More than half a month later, all kinds of shipbuilding tools have been manufactured one after another, the artificial lake has also been excavated, and river water has been introduced.

A long wall surrounded the artificial lake and a wide riverside beach.

A part of the soldiers guarding the second team was assigned to this place to be on duty, and unrelated personnel were not allowed to approach.

Jiang Xuan summoned three apprentices who were more talented in carpentry from the stone tool workshop, plus three soldiers who were more powerful in shipbuilding from the fishing team, a total of six people, became the first batch of personnel in the shipyard.

On the fifth day of June, the Fuji tribe shipyard officially started.

On the day of the start of construction, only Jiang Xuan, Chishao, Uncaria, Shiloach, Nanxing, Nepeta, and six selected people attended.

Next to the artificial lake, there is a large open space, on both sides of the open space are built several tall houses, all of which are mud brick houses.

Jiang Xuan stood in the open space, Chi Shao and others were behind him, and the six shipyard employees were in front of him.

Jiang Xuan started to speak.

"Today is the day when our Fuji tribe shipyard started construction. It should have been lively and lively, but for the sake of confidentiality, no other people can come over."

"Can anyone tell me what the ship was built for?"

A soldier thought for a while and said, "For fishing, for crossing the river."

Jiang Xuan smiled and said: "Yes, you are right, do you know how big the biggest fish is and how wide the widest river is?"

The soldiers looked at each other and 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 straight down to the lower part, and when it joins with other small rivers, it becomes a big river. It's getting bigger and bigger than you can imagine."

"Let's put it this way, if you rock the boat and want to go from one side of the river to the other, you won't be able to shake it for a long time, and you will even be swept away by the big waves and overturn the boat."

"Is the big river the largest water area? No, many, many big rivers will flow into the sea. The sea is countless times larger than our entire southern wilderness, and there are real big fish living in it."

"How big is the big fish? It's as big as a mountain. If it swims to us, the Flying Fish River can't hold it."

Jiang Xuan's description made the six warriors stunned. Their knowledge limited their imagination, making it impossible for them to imagine what the big river and the sea were like.

How much food does a fish as big as a mountain have to eat every day?

Even Chi Shao and the others behind Jiang Xuan were shocked to the point of being speechless.

They have no doubts about Jiang Xuan's words, because Jiang Xuan has created too many things they have never seen or heard of.

They were in a remote corner of the Southern Wilderness. Before, they thought the most was how to survive, and the farthest thought was to build a larger tribe.

But now, Jiang Xuan's words have opened their eyes and let them know that there is a wider world outside the mountain, and many things they can't imagine.

"So, the purpose of our shipbuilding is not only to fish and cross rivers, but also to explore a wider and more exciting world!"

"Of course, it's a bit early to say that."

"Our shipyard has only just started, and the goal at this stage is to make the first real boat out of planks, not canoes made of fire."

"In order to make the boat, the soldiers of the smelting workshop and I specially made a batch of tools. These tools are used by the entire tribe and the shipyard first, so they must be kept secret."

Jiang Xuan's eyes became sharp: "If someone leaks the tool, not only the person who leaked the secret will die, but also the relatives around him will be implicated."

Jiang Xuan's words made the six warriors shudder, and even Uncle and 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 be rewarded very handsomely."

"Okay, everything that needs to be said is finished, I announce that the shipyard has officially started!" After Jiang Xuan finished speaking, he took everyone into the newly built house and showed them brand new bronze tools and these tools. usage.

"This is called a saw. It can easily cut wood, and it can also saw wood into planks. Look at it!"

Jiang Xuan picked up a bronze handsaw, walked to a log, put the saw on it, and pulled it at a constant speed.

"When sawing wood, keep your hands steady, and the saw can't be sideways, otherwise it will be easily caught."

As Jiang Xuan continued to saw down, the bronze handsaw quickly sank into the wood, and the sawdust flew.

"winter!"

It didn't take long for the wood to be sawn into two pieces and rolled around a few times on the ground.

Everyone around Jiang Xuan's eyes lit up, this kind of tool is really useful.

You know, in the past, if they wanted to break the wood, they could only cut it with a stone axe bit by bit, and the bigger wood had to be burned by fire.

Now, with a saw, the wood can be easily sawed, and the speed is increased by an unknown number of times.

"This is an axe, you should be familiar with it, but this bronze axe is much sharper than a stone axe."

Jiang Xuan picked up another bronze axe, chopped it down on the wood, and the axe blade sank deep into the wood.

Afterwards, Jiang Xuan kept swinging his axe, and after a while he cut a plane on the wood.

Those warriors were even more excited. The stone axe would have to chop for at least half a day if they wanted to chop like this.

Jiang Xuan picked up another bronze plane and said, "This tool can cut wood more evenly, just look at it."

Jiang Xuan laid the wood flat on the ground, and then held both ends of the bronze plane with both hands, only to see him push it gently, and a thin line of shavings appeared.

As he kept pushing, the surface of the wood quickly became flat, and no burrs could be seen...

"It's called a chisel..."

Jiang Xuan showed them these bronze tools and explained their usage in detail.

Everyone present, looking at these golden tools, only felt as if they were dreaming, and the whole person was dizzy.
