In the quiet night, a faint firelight flickered quietly in the carpenter's room of the Qingque tribe.

Under the dim light of the fire, a figure was working cautiously, not daring to make any big movements or making any noise, even walking with extreme caution.

It was as if he was worried that if his movements became too big, he would disturb the quiet night.

In the quiet night, time passes quietly, and this figure has been busy here.

It wasn't until the chickens raised by the tribe crowed several times that the fire was extinguished.

Then a man quietly came out of the courtyard of the carpenter's room, and then groped his way through the courtyard towards where he slept.

He walked very slowly during this process.

On the one hand, I am worried that if I walk too fast, I will make footsteps and wake up those living in the courtyard. The other reason is because there are many mats in the courtyard and many people are sleeping.

His vision was poor and he was worried that he might step on someone.

This man's body swayed back and forth as he walked, his steps deliberately slowed down, one person heavier and the other lighter, groping in the night.

After doing this for a while, he had to admit an extremely helpless fact.

The thing is, he can't find where he slept before...

After standing here hesitating for a while, he finally gave up resistance and groped his way towards the wall. Then he found a place where no one was around, sat down with his back against the wall, straightened his legs,

He folded his hands in front of him and soon fell into sleep...

When it gets dark, some people in the tribe have already started to get up. This is because the people in the tribe are preparing to continue working hard for the ongoing harvest.

Lame, who was sleeping against the wall, was awakened by these noises.

He rubbed his head and stood up from here.

At this time, with the relatively weak light, I could barely see.

Lame found the mat he was sleeping on outside. After lying down, he soon fell asleep again.

By the time Lame woke up again, the sun had already risen quite a bit.

Many people in the tribe have already gone to the ground.

Those in charge of cooking were cooking there, and the smoke rising from the cooking pots was accompanied by the smell of fireworks, which made people feel comfortable just looking at it.

When Lame woke up, he soon heard some conversations, the words of those who participated in the shipbuilding together with him.

They were wondering why everyone went to bed and why when they woke up, all the areas that needed improvement on the sailboat's rudder had been improved.

After someone suggested that someone got up in the middle of the night and secretly did the thing, others began to speculate as to who did it.

Listening to the discussion of these people, Lame, who was still lying there, couldn't help but reveal a faint smile on his face.

Then he slowly sat up, pretending to have just woken up, rubbing his eyes with the back of his hand, and then squinted his eyes to look in the direction of the carpenter's room and the people who were discussing there.

It's like I don't know anything about what they said...

Han Cheng already knew this.

Standing at the door of the carpenter's room, he looked at the limping walk here, and then pretended to be like the rest of the people, looking at the modified sailboat in surprise, as if he didn't know anything about it.

Lame, couldn't help but smile helplessly.

This guy!

It's been this long, but I still can't get rid of this habit of being eager to work.

Regarding Lame's behavior, Han Cheng was touched and felt particularly distressed...

"Crash..."

With the sound of water, the sailboat with its white sails lowered was once again lifted out by the tribesmen and put into the water.

Four sailors who had been driving the sailboat for most of the day before stepped onto the sailboat.

On the shoulders of one of them is a large rudder in the shape of a fish tail.

The man holding the rudder went straight to the stern of the sailboat.

Standing limply on the edge of the dock, he vocally instructs the man on how to install the rudder on the stern of the boat.

This matter was not difficult. Under his guidance, the man completed it quickly and installed the rudder on the stern of the ship.

It's just that at this time, compared with last night before the modification, the connection between the rudder and the stern wooden post has changed a lot.

The most significant change is that the iron rod originally used to fix the rudder and the wooden pillar together has disappeared and been replaced by a thumb-thick leather rope made of multiple thin leather ropes.

After the sailor installed the rudder and tied it securely, the other three sailors quickly raised the three fallen sails.

After everyone was ready, one of them walked up to the bow, jumped onto the pier, untied the cable and threw it onto the bow.

Then he stretched out a leg on the bow of the boat and kicked it without much effort, and the whole boat left the dock and slid towards the back.

And he also took advantage of this opportunity, put his other foot on the dock a little hard, and came to the boat.

The sailor standing at the stern of the boat, holding the upper handle of the rudder with both hands, saw this and began to hold the handle of the rudder with both hands and began to imitate the way a fish swims in the water, swinging the rudder left and right, in order to achieve Let the sailboat turn.

At this time, the rudder and the wooden board made into the shape of a fish's tail below had been inserted diagonally into the water, and the whole thing was submerged by the water.

As the man swayed from side to side, the submerged fish-tail-shaped rudder swung from side to side, stirring the water, and it really looked like a fish's tail swinging in the water.

After the leather ropes at the joints replace the iron bars threaded there, the rudder can swing from side to side to the maximum extent.

Although it is not as good as a real fish, it has already made a big breakthrough compared to the previous time.

This is the result after Lai thought about it for a long time and spent a while to transform it.

Following the movements of the sailor at the helm, whether it was the people standing on the shore or the pier, or the three sailors on the sailboat, they all suddenly became energetic, looking at the sailboat with bright eyes, wanting to See if this kind of rudder is easy to use and whether it can bring them miracles!

The miracle happened soon!

"Bang!"

A sound rang out from the pier on the river.

The sailboat that had just left the dock actually returned to the dock at this time and had a very intimate contact with the dock.

It was as if she was extremely reluctant to part with the dock like this.

Looking at the bow of the sailboat that collided with the dock, a group of people standing here waiting to witness the miracle couldn't help but look at each other.

I didn't know what to say, and the scene was a little quiet for a while.

Didn’t I say that the rudder is used for turning?

How come after it started to swing, the sailboat not only didn't turn, but actually returned again?

It took me and others a while to research and manufacture this thing that is specifically used to turn a sailboat. Why does it not look like it makes the sailboat turn at all, but instead looks like it is specifically designed to push the sailboat forward?

Han Cheng was also a little confused.

Logically speaking, whether it is from the perspective of bionics or from some of the knowledge related to the rudder that I have remembered, such a thing should not happen.

The rudder is what is really used to control the steering of the ship...

But looking at the sailboat in front of him that had close contact with the dock, Han Cheng's affirmation became less firm again.

Could it be that I really remembered this matter incorrectly?

However, such doubts did not last long.

Not long after, Han Cheng's heart moved, and a picture suddenly appeared in his mind——

Under the night, a large river lay across here like a dark abyss.

Snowflakes kept falling from the sky.

Both sides of the river were covered with white snow.

The dry and broken reeds, as well as the branches that had lost all their leaves and become bare, were all covered with heavy snow and lost their original shape.

It was at this time that there was a faint creaking sound on the quiet river surface, similar to the sound of wood rubbing against each other.

Also coming along was the gentle sound of water waves.

A man stands at the stern of a ship, facing one side of the ship.

His hands were pressed on a slanted wooden pole at the stern of the boat, and he was constantly swinging from side to side.

Following the man's movements, the ship floating on the river continued to move forward.

When the boat reached the middle of the wide river, the man released the wooden handle and dropped the anchor into the river and stopped.

Then he quietly came to the cabin with another person on the ship, quietly tied up a sleeping man, took out a knife from under a wooden board, put it on the neck of the awakened man, and executed

Robbery.

And asked this person whether he wanted to eat chaos or...

This is a scene from "Water Margin".

The story is that Song Jiang was seriously ill and was in danger. In order to save Song Jiang's life, Zhang Shun crossed the river overnight to find the Earth Spirit Star. The miracle doctor An Daoquan came to treat Song Jiang. He was too sleepy and fell asleep in the cabin while crossing the river.

, the story of being kidnapped by gangsters who robbed a river, snatched gold and silver, and threw them into the river.

This TV scene that Han Cheng watched in later generations appeared in Han Cheng's mind.
