I am a primitive

Land transportation seems to be very easy. People can walk directly with their feet when they are two or three years old.

But that's only for short distances.

Long-distance things involve all aspects.

Not to mention the rest, the road construction alone is enough to make people stop when all conditions are not met.

Opening roads in the mountains, building bridges in the water, such things are done, it is hard to lose your hair.

The investment and technical requirements are simply not too high.

Of course, it is not the roads that require high technology, but the vehicles that drive on the roads.

For long-distance transportation, things like ox carts and donkey carts are not cost-effective.

But Che Hancheng, who burns oil and electricity, can't get it out.

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

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

As for the planes with higher technology, he also felt the cold rain slapping his face indiscriminately.

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

There is no need to think about building roads. The many rivers and lakes scattered throughout the land itself are the best waterways.

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

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

The incomparably huge fleet of Zheng He's seven voyages to the West were wooden ships.

Magellan, who had a fleet that looked extremely shabby compared to Zheng He's fleet, also relied on wooden boats without machinery to complete the feat of circumnavigating the world!

Because he knew the 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 is feasible under the current conditions.

This matter is settled like this!

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

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

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

Of course, if he wanted to bring it up to 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, if you can't get it out by yourself, it doesn't mean that you can't develop in the tribe.

If I am fine, I can record what I know about automobiles, aircraft manufacturing, and the various effects that can be produced after the successful manufacture of automobiles and airplanes, and the significance to the tribe.

Then tell and record some stories about these things with the people in the tribe, let the people in the tribe know these things and have a yearning for them.

With longing, with the direction of efforts, there will be hope.

Humans are often terrifying creatures with astonishing perseverance.

Driven by the hope in the heart, miracles can often be created.

Han Cheng was thinking this way, and suddenly remembered a similar joke, but it made sense.

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

One is a bird that strives to fly first and succeeds in the end.

The other is a lazy and stupid bird that sleeps in its nest and does not fly.

The last one is the most abominable. I am too lazy to fly, so I just lay eggs in the nest, and after the chicks hatch, let the chicks fly to lofty ideals.

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

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

Thinking of this in his heart, he found it quite interesting, shook his head with a smile, and threw this rather weird thought out of his mind.

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

Then he took out a smooth wooden board similar to a drawing board.

Fix the paper on the drawing board with a few small bronze nails, and start painting with a brush.

Seeing Han Cheng laying out these things and starting to draw with a pen, the people on the same boat as Han Cheng and the people around them immediately fell silent.

He speaks in a low voice, and does things lightly.

The boat is walking in the river, the two banks are picturesque, and the clear river is full of waves.

Time passes with the flow of the river.

Sure enough, the dead are like husbands, never giving up day and night.

A world map appeared on the current paper of Han Cheng, who was drawing with a pen.

Of course, just an outline.

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

Especially this kind of thing, after coming to this world, he has done it more than once.

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

He wrote on a continental plate—here there is a tree called the rubber tree, which cuts a hole and produces rubber, which can be used to make rubber tires, which is the best choice for making car wheels.

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

And draw the range of the tropics.

At the same time, he also wrote about the growth habits of rubber trees and the appearance of rubber trees that he knew.

After writing these, Han Cheng stopped his gaze on the plate of Eurasia, and then circled a position closer to the southwest.

It is marked that this place is rich in oil, and the oil is buried underground. It is a black viscous liquid that will catch fire.

Petrol, diesel, kerosene lamps that can be separated from the inside.

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