The elder brother's idea was not wrong at all. Han Cheng had indeed thought of a solution to the problem.
This thing is to install sails on the ship!
Whether it is written in the poem I learned when I was a child - "The shadow of the solitary sail is far away in the blue sky, only the Yangtze River is visible in the sky", or various TV pictures, or it is often hung on the side wall of the living room at home.
The paintings include welcoming pines, a big river, a boat with sails, and a plaque with the words "Smooth sailing" written on it...
This was also a big reason why Han Cheng slapped his forehead violently with his hand.
After all, it was common sense for future generations to put sails on a ship and use the wind to move the ship forward.
As a result, I didn’t think of this until now.
Why doesn't this make people feel annoyed?
After a while, Han Cheng became a little calmer, and he thought about some of the reasons why he had such blind spots in his mind.
First of all, it is influenced by the environment in which later generations live.
In later generations, the place where he lived was either driven by machines to pump river sand, or he ran back and forth on the river, relying on large iron boats that picked up people going to the market on both sides of the river and went to the towns downstream of the river to go to the market.
Either you encounter small wooden boats or small iron boats anchored at various ferries, used to ferry people to the other side.
He had never come into contact with a ship with sails in real life.
Another reason is that over the years, the Fire Tribe themselves have loaded the woven linen on rafts and transported it to the main Qingque Tribe.
The Qingque tribe rarely used boats when traveling long distances along the waterway. In addition, the rivers near the main tribe were narrow, so there was no need for sails.
Under such circumstances, Han Cheng subconsciously did not think about this aspect.
Now I took the people from the tribe down the river. Because I was in a hurry, I quickly thought of the sail.
"Put the reed mat up and hold it up with something like a stick to prevent it from falling down.
If you can't hold it, two people can come over, lift it with your hands, and carry it with your body.
It should be noted that people need to face the direction of the wind."
Han Cheng said to everyone in this way.
In fact, at the beginning, Han Cheng wanted to let the tribesmen pull up the cloth and use it as a sail.
However, except for the clothes worn by people and some bandages for emergency situations, there was no extra cloth for Han Cheng to use in this way.
Moreover, even if there is extra cloth, it will not work, because these cloths are linen and are very breathable.
If the wind blows over, it will leak through these small holes. If you use this kind of cloth as a sail, even if the wind blows very hard, it will not play a big role in promoting the ship.
It was precisely because of realizing this that Han Chengcai did not directly let people try it with linen cloth. Instead, he directly developed his imagination and asked people to use reed mats instead of linen cloth to make a ridiculously simple sail.
After hearing Han Cheng's order, everyone present felt strange and wondered what the Son of God meant by asking him and others to do this.
If you want the boat to sail faster, shouldn't you have to row hard and use pennies to punt the boat?
Why didn't the Son of God ask anyone to do either of these things now? Instead, he asked himself and others to hold up the reed mat?
However, due to the long-term habits and the various deeds they had witnessed with the Son of God, these people of the Qingque Tribe did as Han Cheng said.
While doing it, pay attention at the same time, fully expecting a miracle to happen.
The miracle happened soon.
After the dense reed mat is propped open, the wind blows on the reed mat, and the reed mat leans against the person's body or the stick supported behind, forming a thrust.
This power is much greater than the power the wind had on people and ships before.
Driven by such force, the ship suddenly picked up speed and moved forward.
The boats that had already set up their reed mats quickly left behind those that had not yet set up their reed mats, widening the distance between them.
Seeing such a scene, no matter whether they were people sitting on the boat with the reed mats set up or those who were thrown away without setting up the reed mats, everyone's eyes suddenly lit up.
The Son of God’s method is really a good one!
It didn’t take any effort at all. I just put a reed mat on the boat and the boat ran so fast!
This is much faster than a person paddling hard!
What's more important is that even if a person rows desperately and exhausts himself, the speed may not be faster than the sailing speed of the ship at that time!
The Son of God is indeed the Son of God!
It’s impossible not to admire it!
You can always think of ways to use simple tools to make things extra easy!
With their hearts full of emotion and their minds full of surprise and admiration, those on board the boats who had not set up the reed mats also speeded up and set up the reed mats so that the wind could blow the reed mats and carry them with them.
They run faster...
Han Cheng sat on the boat, feeling the speed at this time, and then a smile appeared on his face.
The way he solved the matter so easily was more in line with his identity and status as a later generation.
Thinking so naughtyly, Han Cheng gradually had some other ideas.
The idea is that after he returns from the Fire Tribe, he will start to gather together some outstanding carpenters from Lai and other tribes, especially those who are experienced in shipbuilding.
Let them start research on sailboats and start trying to build sailboats.
When it comes to long-distance navigation capabilities, sailing ships are undoubtedly much more powerful than the current ships in the tribe.
The existing ships in the tribe are okay for short-distance travel, but for long-distance travel, they are really lagging behind and cannot keep up with demand.
In the past, after Han Cheng came to this world, the tribe was very poor and did not have many things. Under such circumstances, there was no need to pay attention to it. Having a bamboo raft felt very good.
Later, after Lai and others built the wooden boats that were used on the river in his hometown when he was a child based on what he had drawn, Han Chenggong became even more satisfied.
However, one of the characteristics of human beings is called dissatisfaction.
Once you get something good, you want something better.
For many things, satisfaction is only temporary, and dissatisfaction is the norm.
So now, Han Cheng is not satisfied with the small wooden boats that his tribe already owns, and wants to build a sailboat.
Generally speaking, this kind of dissatisfaction has more advantages than disadvantages.
Because of such characteristics, it is not easy for people to be content with the status quo.
It’s not possible that after you achieve some results, you will continue to be complacent and lose your enterprising spirit.
Without these dissatisfactions, human beings would probably have been living in an era of feeding on hair and drinking blood, and would not develop any further.
The development of sailing boats in the tribe is of great benefit to the tribe, and can greatly improve the tribe's ability to sail far away.
As a person from later generations, he clearly understands the significance that large ships can bring!
Moreover, compared to long-distance land transportation and faster and more advanced air transportation, long-distance water navigation has the lowest requirements and is the easiest to achieve.
Land transportation seems very easy. People can walk directly on their feet at the age of two or three.
But this is only a short distance.
Long-distance things involve all aspects.
Not to mention the rest, road construction alone is enough to put people off if all conditions are not met.
Opening roads through mountains and building bridges over water can be done without losing 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 running on them.
For long-distance transportation, ox carts and donkey carts are not cost-effective.
But Han Cheng couldn't get rid of the oil-burning and electric-burning cars.
Just thinking about the various craftsmanship, technology, and materials involved in the various parts of the car, Han Cheng's heart was filled with cold despair.
He really doesn't have the ability to get these things out in his lifetime.
As for the more advanced aircraft, he still felt like the cold icy rain was randomly hitting his face.
Compared with these two modes of transportation, water transportation is much better.
There is no need to consider road construction. The many rivers and lakes scattered throughout the land itself are the best waterways.
All we need to do is continue to improve shipbuilding technology and navigation methods.
Not to mention steamboats, wooden sailing boats alone can conquer the world.
The huge fleet used by Zheng He on his seven voyages to the Western Seas was all wooden ships.
Magellan, who had a fleet that was extremely shabby compared to Zheng He's fleet, also relied on wooden ships without machines to complete the feat of traveling around the world!
Because he knew history and some miscellaneous things that he didn't know how to know in later generations, Han Cheng still knew a lot about these things.
Be able to tell which one is feasible under the current conditions.
This matter is settled like this!
After Han Cheng thought back and forth for a while, he reached out and patted his knee and made this decision.
In terms of long-distance transportation, the priority development is water transportation!
As for land transportation and air transportation, these will slowly develop.
Of course, if he wanted to reach the level of the great country that Han Cheng lived in later generations, Han Cheng said that there was really nothing he could do.
However, just because you can't do it yourself doesn't mean that the tribe can't develop it.
If you are fine, you can record what you know about automobiles and aircraft manufacturing, as well as the various effects that can be produced after the automobiles and aircraft are successfully built, and their significance to the tribe.
Then when nothing happens, tell and record some stories about these aspects to the people in the tribe, so that the people in the tribe know these things and become yearning for them.
With yearning and a direction to work towards, there will be hope.
Human beings are often creatures with astonishing and terrifying perseverance.
Driven by the hope in your heart, you can often create miracles.
Han Cheng was thinking this in his heart, and suddenly remembered a similar paragraph, but it made sense.
It is said that there are three types of stupid birds in this world.
One is a bird that tries its best to fly first and finally succeeds.
The other kind is a bird that is still lazy and stupid, lying in its nest without flying.
The last one is the most abominable. They are too lazy to fly, so they just lay eggs in the nest. After the chicks hatch, they let the chicks fly towards their lofty ideals.
Han Cheng felt that his current psychology and what he was about 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 this in his heart, he found it quite interesting. He smiled and shook his head, getting rid of this rather weird thought from his mind.
Then he took out a piece of paper from his backpack, folded them together, stretched them out, and came out with the boss's paper.
Then he took out a smooth wooden board similar to a drawing board.
Fix the paper to the drawing board with a few small bronze nails and start to draw.
Seeing Han Cheng lay out these things and start painting, the people on the same boat with Han Cheng and the people around him immediately became quiet.
He speaks with a suppressed voice and does things lightly.
The boat is walking in the river, the scenery on both sides is picturesque, and the clear river water is filled with waves.
Time keeps passing by as the river flows.
As expected, the deceased was like a man who never gave up day and night.
Han Cheng, who was drawing, had a world map on the current paper.
Of course, it's just an outline.
As a liberal arts student who is very good at geography, it is not that difficult for him to draw the outline of a world map that is not very standard with freehand.
Especially after he has done this kind of thing more than once after coming to this world.
After drawing the outline, Han Cheng held the pen in his hand and studied it for a while. After thinking about it, he started writing on the map.
He wrote on a continental plate - There is a tree here called the rubber tree. Cut the openings to get out the rubber, which can be used to make rubber tires, which is the best choice for making car wheels.
After making such annotation, Han Cheng thought for a while and drew the equator.
And draw the scope of the tropics.
At the same time, he also wrote down some of the growth habits of rubber trees that he knew and the appearance of rubber trees.
After writing these, Han Cheng's eyes stopped on the Eurasian continental plate, and then made a circle closer to the southwest.
It was noted that this place is rich in oil. Oil is buried underground and is a black, viscous liquid that will ignite when exposed to fire.
Gasoline, diesel, and kerosene lamps can be separated from it.
Among them, gasoline is an indispensable fuel for the operation of cars.
It is equivalent to the fodder fed to cattle by bullock carts...
…
Time was passing, and Han Cheng was still marking things on the world map.
At this time, many things have been marked on the map.
He has already marked all the information he knows about the raw materials needed to make cars, as well as the information about the places containing the most raw materials.
Han Cheng wanted to put the map away, but then his eyes fell on the island not far east of the Eurasian continent...
