Because the tribe's initial prosperity and the first food they obtained were fish, and now the tribe has its own fish ponds, rivers, and even a super large fish pond and wild duck lake, so the people in the tribe are not unfamiliar with fish.

Especially for veteran indigenous people of the Qingque tribe like Bo, they don’t even know how much fish they have eaten.

They have seen and eaten many fish, and they know very well what fish look like.

But at this time, they all gathered together, looking carefully at the fish that was caught and put into the basin.

They stared at him one by one, like a bunch of country bumpkins who had never seen the world.

The fish in the basin was terrified.

It had seen many humans before, and had never taken them seriously.

Because at that time it was in the pond and thought it had a vast world. It only needed to swim in the water or dive under the water, and it didn't have to worry about what these guys who couldn't go into the water could do to it.

It's the same even if you blow bubbles at them.

But it’s no longer possible. Now I have been caught and the big pond has become such a small pond. There are no stones in the water and no silt at the bottom.

I tried so hard to dive down that my chin was almost knocked crooked by this hard object, but there was no result at all...

This is not even more terrifying. What is even more terrifying is that these horrible perverts would occasionally point their evil fingers at me, poking me on the forehead or other parts of my body, not letting me live in peace.

The fish was poked back and forth in the water by the damn man's fingers for a long time. Feeling pain all over, it spit out a string of bubbles in fear at the evil man.

It can't speak. If it could speak, it would definitely make a tearful accusation against these people at this moment.

Is it pretty?

Is it pretty?

Am I pretty?

You guys always stab me...

Soon, this was not the only terrified fish.

Several other fish of different species were fished out and placed in several basins. Like the first fish that was fished out, they were watched and touched by evil fingers of evil humans.

"... generally, fish that are relatively thin, have narrow bodies, and large tails are more agile when turning..."

"The fish's tail is still in the middle of its body..."

"The fish's tail is thin, wide and big, much smaller than their head..."

After careful observation and who knows how many times they had stretched out their evil hands to these poor fish, under Han Cheng's organization, those who participated in the shipbuilding began to talk about what they had learned from their previous observations.

After talking like this for a while, when no one was able to say anything, Bo, the chief engineer of the shipyard, began to summarize these things.

After summarizing the things obtained from the fish, Bo and others basically had an idea of ​​what this thing, which the Son of God called a rudder, was, something they had never seen before.

It's not particularly clear, but I have some ideas about how to do it and how to install it.

In order to be as accurate as possible, after finishing these things, the people in the tribe watched the fish separately, poked them with their fingers, and then gathered together to discuss it. Finally, they determined that there was nothing that could be obtained from these fish for the time being, so they let these poor fish go and started making rudders that could turn the sailboat.

Of course, these fish cuts are accompanied by the aroma of food.

The reason why they were not put back into the pond was that they had been out of the pond for such a long time, and in the process, a lot of scales had fallen off.

Some who could not bear the torture had developed new skills and began to swim sideways or backstroke with their bellies turned over.

In this case, even if they are put back into the pond, they will most likely not survive.

In order to avoid waste, we can only give them another form of freedom and liberation.

As for the problem that the rudder was not working well and the fish that were initially observed could not be found, the people in the tribe did not have to worry about it at all.

Because just like everyone looks the same in their eyes, fish of the same species also look the same in the eyes of humans.

The only difference is in size, fatness and thinness...

When the time comes, just catch some from the pond or river...

The carpenter's room became lively again.

People involved in shipbuilding gathered together and were busy here based on their latest achievements.

Everyone was in very high spirits.

Because this time the method was inspired by the Son of God, and people came up with it by observing fish that can move flexibly in the water.

Everyone is involved in this process.

Moreover, everyone was eager to know whether this method of applying the inspiration gained from observing animals to the manufacture of tools for their own tribe would be useful.

If it is really proven to be useful, then there is no doubt that a brand new and extremely bright door will open to them!

Inspired by this incident, their thinking will become more open and their vision will be longer-term.

It will move from a narrow, fixed place to more places.

Once something like this happens, there will naturally be many benefits for the Qingque tribe!

This will promote the development of the Qingque tribe and make the Qingque tribe better.

A pioneer named Ma once said that hand mills bring about a feudal society, while steam mills produce a society of industrial capitalists.

This sentence can largely reveal how important tools, or the science behind these tools, are to the progress of human society.

As far as Han Cheng knows, even in the future where he lives and technology is very advanced, observing living things, gaining inspiration from them, and eventually deriving all kinds of strange and high-end things have always been happening and will continue to happen.

Looking at the tribal carpenters who were busy in the carpentry room with full concentration and shining faces, Han Cheng couldn't help but smile.

Before this matter started, he only thought that this method could be used to solve the problem of manufacturing sailboats for the tribe.

But now it seems that in addition to solving this problem, the people of my tribe will get bigger, more, and better things...

The sun disappears over the horizon.

Although the earth was still stuffy without the sun shining on it, it was much better. At least there was no burning sensation from the direct sunlight shining on the body.

The sun disappeared and dusk fell. The tribe did not become quiet, but became more lively...

The Qingque tribe is most comfortable at night during the busy farming season.

The weather has become much cooler and everyone is relatively relaxed.

The sky is filled with stars inlaid in the deep night sky, and a wide glowing belt stretches across the sky, which is particularly beautiful.

In the distance outside the courtyard, you can hear the sound of gongs being struck and there are flickering lights.

This is the night watchman of the tribe, who is inspecting the threshing floor in the distance and the unharvested millet fields, worried that something might come and destroy the precious food of the tribe.

There were little sparks of fire flickering, and sometimes it was hard to tell whether they were stars in the sky or flames on the ground.

Many people were sleeping in the courtyard of the tribe, enjoying the coolness of the night.

Some adults were holding fans made of broad grass leaves or large leaves from the shells of bamboo shoots. They lay there and rocked them slowly, fanning themselves and the sleeping children around them, and driving away the annoying mosquitoes at the same time.

After washing up, people lie down here and feel extremely comfortable.

The Qingque tribe was quiet under the night sky, just like the peaceful night.

However, there was one place where the lights were still on.

This is the carpenter's room of the Qingque tribe.

Under the light of the fire, many people were busy in the carpenter's room.

Bo and the others who participated in the shipbuilding were there.

As everyone was busy, something appeared in front of everyone.

This thing has a strange shape and is divided into two parts.

There is a long wooden handle on top.

At the bottom of the wooden handle is something made of a wooden board.

The shape of this thing is a big fish tail.

This is the rudder they made.

The sailboat that was carried to the river for half a day of testing yesterday was now carried back to the courtyard of the carpenter's room.

At this time, a wooden pillar had been installed directly behind the stern.

There was a cut on the wooden pillar, from front to back.

Lame stood here, bending over and looking carefully at the fishtail-shaped object.

After seeing that there was nothing wrong with it, he picked it up and installed it on the stern of the ship.

The handle of the rudder was stuck in the groove of the wooden pillar installed at the stern. It was moved up and down for a while, the position was adjusted, and after making a mark with a charcoal pencil, it was removed, and then someone started to drill holes with a hand drill.

After the hole is drilled, insert the rudder into the wooden pillar again, align the hole on the wooden pillar with the hole on the rudder, and pass it through with an iron rod.

The gap on the wooden pillar is very large, much wider than the wooden handle, and there is still plenty of space to the left and right after it is stuck inside.

This was left out intentionally.

In this way, the rudder is stuck inside with a lot of room to move.

After putting it on, Bo thought for a while, then climbed onto the sailboat with the help of a stool, stood on it, held the handle of the rudder with his hands, and shook it back and forth for a while to get a feel for it.

As he shook the boat, the rudder, which was like a fish tail, also swayed from side to side.

After feeling it for a while, Lame shook his head.

He felt that the left and right swinging amplitude of the tail below the rudder was still too small.

When they observed the fish today, they found that when the fish turned, especially when they turned their heads, their tails were often bent.

The swing can extend beyond the fish's head in front.

And now, the swing of this rudder is obviously far beyond the widest part of the hull.

Lame stood here and watched for a while, then pulled out the iron rod, removed the rudder, and found tools to re-enlarge the hole on the rudder.

And without affecting the strength of the wooden pillar at the stern, the gap in the wooden pillar was widened again.

After a while of hammering and banging, it was rested and assembled together again.

Bo boarded the sailboat again, stood on it, held the tiller and swayed it left and right, while carefully observing the swing amplitude of the rudder tail.

Compared with the time before the rest, the swing amplitude is much larger.

But after looking at it for a while, Lame was still not satisfied.

But at this time, neither the hole on the ship's tiller nor the hole in the wooden pillar at the stern used to fix the rudder can be further enlarged and thickened, otherwise it will affect their sturdiness.

Bo stared at the connection between the rudder and the wooden pillar, and fell into deep thought...

It was late at night. Han Cheng, who was lying under the gourd shed, turned his head to look at the light still on in the carpenter's room and shook his head helplessly.

He put down the fan in his hand, then tiptoed out of his clothes, put on his shoes, walked around the bed where Sister Bai Xue, Xiao Xing'er and his youngest son slept, and walked towards the carpenter's room where the lights were on.

People like Lame are really hard-working and always want to finish the work as soon as possible.

"Don't do it anymore. Go to bed early. No matter how much is left, leave it for tomorrow! The work cannot be finished in one day. There are many days ahead. If you can't finish it in one day, do it in two days. If you can't finish it in two days, do it in three days.

Otherwise, if this continues for a long time, it will be too late to make your body healthy. "

After Han Cheng came here, he looked at everyone in the carpenter's room and said this.

"Son of God, just wait a little longer and it will be done."

After hearing what Han Cheng said, Bo smiled and said to Han Cheng.

"No, stop doing it, put it down and go back to sleep."

Han Cheng shook his head and refused directly, not giving Bo any chance to compromise.

"The sailboat is just an important thing. In addition to the sailboat, the tribe will continue to make other things in the future. I will be busy in the future. Only by taking good care of myself can I make greater contributions to the tribe in the future..."

Han Cheng thought about it and added.

Under Han Cheng's tough attitude, the lights in the carpenter's room were turned off, and everyone left. After washing themselves with water, they returned to their own sleeping places to sleep.

Although the work was stopped by the Son of God, everyone felt warm in their hearts...

The night became quiet again, with snoring sounds in between.

I don't know how much time passed, but someone quietly got up and groped his way to the carpenter's room...
