Senior Brother was not wrong at all, Han Cheng really thought of a solution to the problem.

This thing is to load the sails on the ship!

Whether it is written in the poem I learned when I was a child - 'The lonely sail is far away and the blue sky is exhausted, only the Yangtze River skyline flows', or a variety of TV pictures, or the paintings often hanging on the side wall of the living room at home have a welcoming pine, a big river, a boat with sails, and a plaque that says smooth sailing......

This is also a big reason why Han Cheng slapped his forehead with his hand.

After all, attaching sails to a ship and using the wind to move the ship forward is simply common sense for future generations.

As a result, I didn't think about it until now.

How is this not frustrating?

After a while, Han Cheng became a little calm, and he thought of some of the reasons why he had such a blind spot in his thoughts.

The first is the influence of the environment in which the future generations live.

In later generations, the places where he lived were either driven by machines and used to pump river sand, or large iron boats that ran back and forth on the river, relying on people who were on both sides of the river to catch the market, and went to the towns downstream of the river to catch the market.

Either you encounter small wooden boats or small iron boats moored at various ferry crossings to ferry people to the other side.

A ship with sails, which he had never touched in real life.

Another reason is that over the years, it was the Fire Tribe itself that had transported the spun linen cloth on rafts to the Blue Sparrow Lord's tribe.

The Blue Sparrow tribe rowed boats, and when they ran long distances along the waterway, they basically didn't have it, and the rivers near the main tribe were narrow, so they didn't need sails.

Under such circumstances, Han Cheng subconsciously didn't think about it.

Now with the people of the tribe, down the river, because they were in a hurry, they quickly remembered the sail.

"Put the reed mat upright and hold it up with something like a stick, and don't let it fall over.

If you can't hold it, come up with two people, hold it in your hands, and carry it with your body.

Note that the need is the direction in which the person is facing the wind. ”

Han Cheng said to everyone in a loud voice.

In fact, when Han Cheng first wanted the people in the tribe to pull up the cloth and use it as a sail.

It's just that apart from the clothes worn by the people and some bandages used to deal with emergencies, there is no extra cloth for Han Cheng to use like this.

Moreover, even if there is excess cloth, it is not possible, because these cloths are linen cloth, and they are very permeable.

When the wind blows, it will leak through these small holes, and the sails made of such cloth, even if it blows a strong wind, will not have much effect on the ship.

It is precisely because of this realization that Han Cheng did not directly let people try it with linen, but directly developed his brain, and let people use reed mats instead of linen cloth to make simple and outrageous sails.

Hearing Han Cheng's order, everyone present felt strange, and they didn't know what it meant for Shenzi to let him and others do this.

If you want to make the boat sail faster, shouldn't you let people row hard and prop the boat with penny?

Why didn't the Son of God let people do either of these things now, but let himself and others prop up the reed mat?

However, the habits that had been formed for a long time, as well as the various deeds of witnessing miracles with the Divine Son, these people from the Qingque tribe still did what Han Cheng said.

While doing it, I was paying attention, and I was full of anticipation for a miracle to happen.

Miracles soon happened.

After the dense reed mat is propped up, the wind blows on the reed mat, and the reed mat leans against the person's body or the stick supported behind it, forming a thrust.

This is much more powerful than the wind that blew on people and ships before.

Driven by such a force, the ship suddenly sped up and headed forward.

Those ships that had already put up their reed mats quickly left those that had not yet done so behind and distanced themselves.

Seeing such a scene, whether it was the people sitting on the boat with the reed mats or those who were thrown away without the reed mats, their eyes suddenly lit up.

The Son of God's method is really a good way!

It didn't take much effort at all, just put the reed mat on the boat, and the boat ran so fast all at once!

That's a lot faster than a human paddling hard!

What's more, people are desperately rowing and tired, and the speed is not necessarily faster than the speed of the ship at this time!

The Son of God deserves to be the Son of God!

It's impossible not to admire!

Always come up with ways to make things extra easy with simple tools!

Under such admiration full of emotion and amazement, those on the boats who did not have the reed mats in place also sped up and put the reed mats up, so that the wind could blow the reed mats and lead them faster......

Han Cheng sat on the boat, feeling the speed at this time, and only then did some smile appear on his face.

The appearance of solving the matter in such a fluttering way is more in line with his identity and status as a descendant.

Thinking about it like this, Han Cheng gradually had some other ideas.

The idea was that when he returned from the Fire Tribe, he would begin to gather the good carpenters of the Cripple and other tribes, especially those who were very experienced in shipbuilding.

Let them start researching on sailboats, and start trying to build sailboats.

When it comes to long-distance sailing, sailing ships are undoubtedly much more powerful than the current ships of the tribe.

The existing ships in the tribe are okay for short-distance running, but for long-distance travel, they are really a little behind, and some can't keep up with the demand.

In the past, after Han Cheng came to this world, the tribe was poor and white, and there were many things, in that case, there was no need to pay attention to it, and it was very good to have a bamboo raft.

Later, after Lame and the others made the wooden boats on the river in his hometown when he was a child according to the things he had drawn, Han Chengcheng became even more satisfied.

However, one of the characteristics of human beings is called dissatisfaction.

If you get the good, you want to get the better.

For many things, satisfaction is only temporary, and dissatisfaction is the norm.

So now, Han Cheng began to be dissatisfied with the small wooden boat that his tribe already owned, and wanted to make a sailboat.

This dissatisfaction, on the whole, is more beneficial than disadvantageous.

Because of such characteristics, it is not easy for people to be satisfied with the status quo.

After achieving some results, he has been complacent and has lost his enterprising spirit.

Without these dissatisfactions, human beings would probably have been living in an era of blood drinking, and would not have gone any further.

The development of sailing ships in the tribe is of great benefit to the tribe, which can greatly improve the tribe's ability to sail long distances.

As a man from the afterlife, he knew exactly what it meant to be a big ship!

Moreover, compared to long-distance land transportation and faster and more advanced air transportation, long-distance water transportation is the least demanding and easiest to achieve.

Land transportation looks easy, and people will walk directly on their feet at the age of two or three.

But this is only for short distances.

Long-distance things, involving all aspects.

Not to mention the rest, the mere construction of roads, when all conditions cannot be met, is enough to make people stop.

Open the road in the mountains, build bridges in the water, such things are done, and you don't want to lose your hair.

The investment and technical requirements are simply not too high.

Of course, it is not the roads that are technically demanding, but the vehicles that drive on the roads.

Long-distance transportation, ox carts, donkey carts and other things are not cost-effective.

But the car that burned oil and electricity Han Cheng couldn't get it.

Just thinking about the various processes, technologies, and materials involved in the various parts of the car, Han Cheng's heart was filled with cold despair.

These things, he really didn't have the ability to get them out in his lifetime.

As for the higher-tech planes, he also felt that there was a cold ice rain slapping indiscriminately on his face.

Compared to these two modes of transportation, water transportation is much better.

There is no need to think about road construction, and the many rivers and lakes that are all over the land are the best waterways.

It is only necessary to continuously improve the technology of shipbuilding and the means of navigation.

Not to mention steamboats, wooden sailboats alone can dominate the world.

At that time, Zheng He's huge fleet of seven voyages to the West was a wooden ship.

Magellan, who looked extremely shabby compared with Zheng He's fleet, also relied on wooden boats without machines to complete the feat of traveling around the world!

Because he knows history, as well as some miscellaneous things that he didn't know how to know in later generations, Han Cheng still knows a lot about these things.

Be able to tell which is feasible under current conditions.

This matter is settled!

After thinking back and forth for a while, Han Cheng reached out and patted his knee like this, making such a decision.

In long-distance transportation, the priority development is water transportation!

As for land transportation, as well as air transportation, this will all develop slowly.

Of course, if he wants to reach the level of the great country in which Han Cheng lived in later generations, Han Cheng said that he really can't do anything.

However, if you can't get it yourself, it doesn't mean that the tribe can't develop.

When you are fine, you can record what you know about the manufacture of automobiles and airplanes, and the effects that can be produced after the success of automobiles and airplanes, and the significance to the tribe.

Then when there is nothing to do, tell and record some of these stories with the people in the tribe, so that the people in the tribe know these things and yearn for them.

With yearning and the direction of efforts, there will be hope.

Man is a terrifying creature with incredible perseverance in many cases.

Driven by the hope of the heart, miracles can often be achieved.

Han Cheng thought this in his heart, and suddenly remembered something similar to a paragraph, but it made sense.

It is said that there are three kinds of stupid birds in this world.

One is the bird that strives to fly first and eventually succeeds.

The other is a lazy and stupid bird that lies in the nest and does not fly.

The last one is the most hateful, he is too lazy to fly, so he lays eggs in the nest, and after hatching the bird, let the bird fly to the lofty ideal.

Han Cheng felt that his current psychology and what he was going to do were very similar to the third bird.

If you can't do it yourself, leave it to future generations and let them do it.

Thinking like this in his heart, he found it quite funny, smiled and shook his head, throwing this strange thought out of his mind.

Then he took out a piece of paper from his backpack that was folded together and unfolded.

Then he took out a smooth wooden board that resembled a drawing board.

Fix the paper on the drawing board with a few small bronze nails and start to draw with a pen.

Seeing Han Cheng put these things out and began to draw with a pen, the people who were in the same boat with Han Cheng, as well as the people around him, immediately fell silent.

Speak with a suppressed voice, and do things lightly.

The boat walks in the middle of the river, the banks are picturesque, and the clear water is flooded with layers of waves.

Time goes by as the river flows.

Sure enough, the deceased is like a husband, reluctant to give up day and night.

Han Cheng, who was drawing with a pen, had a world map on his current paper.

Just an outline, of course.

As a liberal arts student who is very good at geography, it is not very difficult for him to draw the outline of a world map that is not very standard by hand.

Especially something like this, after coming into this world, after he has done it more than once.

Drawing the outline, Han Cheng held the pen in his hand and looked at it for a while, and after thinking about it, he began to write on the map.

He wrote on a continental plate that there was a tree called the rubber tree, which cut the openings and made rubber to make rubber tires, which was the best choice for making automobile wheels.

After making such a mark, Han Cheng thought about it and drew the equator again.

And draw the extent of the tropics.

At the same time, he wrote about the growth habits of rubber trees that he knew, and what they looked like.

After writing this, Han Cheng's gaze stopped on the plate of the Eurasian continent, and then circled a position closer to the southwest.

It is noted that there is an abundance of oil here, and oil is buried in the ground, which is a black viscous liquid that will catch fire when encountered.

Gasoline, diesel, kerosene lamps that can be separated from it.

Among them, gasoline is an indispensable fuel for the operation of automobiles.

It's the equivalent of the fodder that an ox cart feeds to a cow......

……

Time is passing, and Han Cheng is still marking on the world map.

At this point, there were already a lot of things marked on the map.

He's done with what he knows about the raw materials he needs to make cars, and where they contain the most raw materials.

Han Cheng wanted to put the map away, but then his gaze fell on the islands not far to the east of the Eurasian continent......
