Sailboats are heavy.

However, due to its size, no matter how heavy it is, it is not that heavy.

Using ropes and wooden bars, it only took six people to easily carry it all the way to the river.

Han Cheng followed and looked at the scene in front of him, and some things came to his mind.

It seems that we can no longer build sailboats in the carpenter's room from now on.

This kind of small sailboat model is still okay, and people can lift it easily. But later, when a large sailboat was made, it would be really difficult to lift it outside.

Even if the people in the tribe could find a way to carry it out, the gate of the tribe would not be able to adapt.

The gate was too narrow to allow the huge body of the sailboat to pass through, so it had to be cracked.

Han Cheng didn't want such a thing to happen.

It seems that next I have to consider where to build a shipyard specifically for manufacturing ships.

In this way, not only will it be convenient to put the boat into the water after it is built, but it can also free up space such as the carpenter's room in the tribe, allowing the carpenter's room and the courtyard to return to their previous state and not be too crowded.

Of course, in addition to these, after the shipyard is built, the division of labor among carpenters in the tribe will become clearer.

The functions are clearer.

It will help the carpenters in the tribe to develop towards specialization and improve the level of carpenters in the tribe.

Thinking about these things in his mind, Han Cheng followed everyone and came to the tribe's dock.

After a while of hard work, the tribe's three-masted sailboat successfully entered the water.

The embarrassing situation of the ship starting to leak and sink as soon as it enters the water will not happen. After all, the people in the tribe already have certain experience in shipbuilding.

Such a low-level mistake will not be made.

The small sailboats with white sails are particularly conspicuous at the dock.

After all, apart from it, the rest are ordinary flat wooden boats in the tribe.

There are also some bamboo rafts on the side.

Under such circumstances, the sailboat with three white sails was as conspicuous as a crane standing out among a flock of chickens or a donkey among a flock of sheep!

The sailboat did not experience any embarrassing incidents such as leaking or sinking, but some small accidents did happen.

There is always a breeze blowing habitually by the river in the early morning.

The newly built sailboat had just been launched and there was no time to tie the ropes.

And the sails were still open at this time.

With these conditions coming together, the sailboat, which had just been launched, sailed away very quickly before anyone could react.

Leaving behind a group of Green Bird tribe members who were looking at it with surprise and joy on their faces.

There were still smiles on the faces of Bo and others.

The sailboat made by himself and others seemed to be very successful. As soon as it was put here, it ran very smoothly without any people rowing it.

And the speed is not slow.

What the Son of God said was indeed correct, this sailboat is indeed a good thing.

More than an average ship.

Very useful...

Bo and others stood here looking at the sailboat, expressing their feelings with satisfaction.

Han Cheng looked at the people whose faces had smiles, surprise, or satisfaction, and couldn't help but scratch his head.

What is this operation?

Shouldn't we be chasing after the sailboat that's escaping alone at this time?

It would be fine if you were standing here indifferent, but why are you looking at the sailboat escaping away alone with the wind, with such excitement and happiness on your faces, as if you had seen the most romantic thing in the world?

Are you stupid?

"The sailboat is running away, chase it!"

After a while, Han Cheng looked at the people in the tribe who were still grinning foolishly and seemed indifferent, so he stopped waiting and started shouting loudly.

After hearing him shout like this, everyone present was stunned for a moment, and then they realized that there was no one on the sailboat, which seemed so magical to them and could go upstream on its own without anyone rowing.

Just an empty ship ran away.

So, the next moment, this place became lively.

Someone jumped onto a small boat, untied the rope, and used a bamboo pole to push the boat towards the freedom-loving sailboat.

Those who are good at swimming simply took off their shirts and entered the water.

He paddled quickly towards the escaped sailboat.

After a while, someone successfully boarded the sailboat.

However, the situation did not improve. The people who boarded the sailboat continued to run forward as the sailboat carried them.

At that time, there was no time to equip the sailboat with oars and other things.

After a period of confusion, the three people who climbed onto the sailboat used the bamboo pole to poke the water and helped the sailboat turn.

"Put on some more effort. It's hard to row against the wind."

After turning the sailboat around, someone spoke up.

As he said this, he picked up the bamboo pole in his hand, touched the riverbed, and began to row the boat with all his strength.

The boat moved forward following his movements.

The man couldn't help but be stunned for a moment.

Because the boat sailing against the wind was not as heavy as imagined, and it was even easier to row than usual.

When it was propped up, it was very light and did not require much strength at all. The boat immediately sailed towards the bottom against the wind, and the speed was quite fast.

The man took one look at the other two people on the boat who were holding oars, and felt relieved.

He didn't think about it anymore and continued to use his hands to push the bamboo pole to push the sailboat downwards.

He was trying hard to row the boat and did not notice the surprised expressions that appeared on the faces of the other two people one after another.

With the hard paddling of several people, the sailboat soon returned to the dock.

The people on the boat were all experienced rowers. When the boat was a certain distance away from the dock, they stopped rowing and instead took the bamboo poles in their hands and dragged them on the water.

The tail of the bamboo pole glided on the water, leaving a trail of water and some waves.

According to previous boating experience, if the boat stops at such a long distance from the dock, it will slowly slide to the side of the dock.

However, this time there were some surprises.

After they stopped rowing, the boat still headed towards the dock against the wind, but the speed was not as expected.

As the ship slid forward, its speed slowed down a bit, but not much.

At first, the people on the boat didn't pay much attention to it.

They felt that there were three sails on the ship, which were facing the wind at this time. With them, the speed of the ship would soon slow down.

However, they soon stopped thinking so.

After the speed of the sailboat dropped a little, it stopped dropping and maintained this speed as it crashed into the dock.

"Hurry up and hold on!"

Although this situation feels particularly strange, this is obviously not the right time to feel strange about it.

On the sailboat, a man shouted loudly, and quickly raised the bamboo pole dragged behind him and thrust it diagonally into the muddy water in front of the boat.

The force carried by the sailboat caused the bamboo to bend.

The other two people also reacted one after another, and they stuck the bamboo poles in their hands into the mud in the water, and worked together to support the sailboat.

Thanks to the joint efforts of these three people, the sailboat finally stopped about half a meter away from the dock.

Seeing this, several people couldn't help but breathe a sigh of relief.

Not only them, but also the people standing on the dock and the shore couldn't help but breathe a sigh of relief when they saw this scene.

What happened just now does seem a bit scary.

"This is the cable. Tie the boat up with it to prevent it from running away again later."

As Lame said this, he threw a coil of rope onto the bow of the sailboat and held the other end in his own hand.

The people on the boat took the rope and tied it to the place reserved for tying ropes on the bow.

At this time, the gusts of morning breeze were not coming.

Several people tied the rope and went ashore one by one.

Together with everyone, we looked at the sailboat with some curiosity.

It was at this time that a morning breeze blew again.

Looking at the cable that was firmly tied there, everyone present couldn't help but feel relieved.

Faced with this thick and strong rope, no matter how strong the wind is, there is no way the sailboat can be blown away!

However……

The next moment...

"Bang!"

A noise suddenly came at this moment, and along with it there was a sense of vibration.

The people of the Qingque tribe, who had been full of confidence just now, were a little confused for a moment.

Their eyes fell on the sailboat that was in close contact with the dock, and they all looked dazed.

What's going on?

How did this collide with the pier?

Their eyes fell on the sail that was facing the wind and rustling a little in the wind.

With these sails, shouldn't the sailboat be blown upwards along the wind at this time, straightening the ropes?

Just like the sailboat was blown all the way upwards by the wind just now.

How did it become like this now?

Not only did he not run backwards with the wind, but he was actually running forward against the wind?

Are these large sails being treated as decorations?

The few people who had just paddled the sailboat and managed to get down from the top felt the situation more clearly.

They had felt something strange when they were rowing the boat before, but now when they saw the sailboat docked against the wind and in close contact with the dock, these strange feelings in their hearts suddenly became extremely clear and they found the root cause!

Han Cheng, who was standing nearby, was also stunned for a moment.

In his subconscious, sailboats have always relied on wind power and sailed with the wind.

Otherwise, how could there be such blessing words as "smooth sailing"?

But what is happening now?

How come this ship is moving forward against the wind?

Han Dashenzi, a half-baked man from later times, was a little confused for a moment when facing the small sailboat made by the tribesmen under his instructions.

I can't figure out what the situation is.

Ride the wind and waves?

Riding the wind and waves...

These words suddenly emerged in Han Cheng's confused mind.

Then, other related things appeared in my mind.

The things that appeared were certainly not the twenty or thirty sisters who were about the same age as his parents and were of the aunt-like generation, but some memories that he had never remembered in the past, but were triggered by the scene he saw before his eyes at this moment.

This memory is related to sailing, or to be more precise, it is related to the sail.

It is said that when the front of the sail faces the wind, the wind passes through the two sides of the sail that is bent backwards, and then forms a driving force behind the sail. Then, relying on this driving force, the boat can go against the wind.

The memories of things that he had seen somewhere before appeared in his mind, and Han Cheng felt relieved all of a sudden.

After deciding to build sailboats in the tribe, Han Cheng had worried countless times about what to do if the person driving the sailboat encountered headwinds during the voyage.

In this case, the ship will not only be unable to sail forward, but will also start to move backward.

The situation before him and the things that emerged in his mind immediately resolved the doubts in his heart.

Thinking about this in his mind, Han Cheng couldn't help but look at Bo and others beside him.

I saw that Bo and other people who participated in the manufacture of the sailboat had basically turned their eyes to look at Han Cheng, the Son of God.

It was obvious that he wanted to get some explanation from the Son of God about this counterintuitive phenomenon.

Seeing this, Han Cheng couldn't help feeling relieved.

Fortunately, a flash of inspiration suddenly occurred to me and I remembered some knowledge about this aspect.

Otherwise, facing the inquiring gazes of everyone in the tribe, I really wouldn’t know how to answer.

This undermines the tall and mighty image of the Son of God of his tribe.

"Son of God, what's going on?"

Sure enough, not long after Han Cheng realized this, Bo started asking.

The others also looked at Han Cheng with confusion and surprise.

Seeing this, Han Dashenzi couldn't help but stand up a little straighter.

Then he spoke confidently.

The Green Bird Tribe’s Son of God’s small classroom begins now.

Han Cheng organized the things he remembered into words, added some of his own understanding, and began to tell them to everyone in the tribe.

After a while, Han Cheng stopped talking, leaving the people of the Qingque tribe full of surprise.

This was the first time they had heard of this theory.

But considering the facts they had just seen and looking at the serious look of the Son of God, they had to believe in the correctness of these statements.

"Son of God, if this is the case, wouldn't it be possible for people from our tribe to go out on such a sailboat and encounter a headwind and still be able to sail forward?

Someone said this excitedly.

The eyes of the others also lit up.

"That's it."

Han Dashenzi nodded as if everything was under my control.

There was some doubt on Lame's face.

Because he thought of some things that the Son of God had once commanded...
