Datang: Time travel in two months, wait online, hurry up!

So even shipping was slow and costly at the time.

If he travels through the past, he must improve the means of transportation and increase the transportation capacity.

Otherwise, with so many industries under his name, all kinds of goods are sold all over the country, and it will be a year of the monkey by the time the goods arrive.

Moreover, the transportation cost is so high, how can it be possible to lose all profits on transportation?

The bicycle is really good. Although it can't carry much cargo, the speed can still be increased many times for a single traveler!

As for the difficulty of producing bicycles, it is actually not that high.

The technical difficulties are mainly in bearings, chains, rims and tires.

Although it is difficult, it is not too difficult. It is mainly the technology and knowledge of processing. He will focus on learning and understanding next.

As for the tires, before there was no rubber, he could only use wooden wheels, but since he decided to bring rubber tree seeds, the tires can naturally use pneumatic tires.

Pneumatic tires are more labor-saving and wear-resistant than wooden wheels, and they drive more smoothly.

Especially when encountering bumpy roads, the driving experience of pneumatic tires is much better than that of wooden wheels.

The only thing that is a little troublesome is that the bicycle needs to be learned!

He still remembers the scene of learning to ride a bicycle in the orphanage when he was a child. At that time, he fell down countless times before he gradually mastered his balance and learned to ride a bicycle.

But it's not a big problem. With the convenience and speed of bicycles, everyone will naturally learn how to ride them.

As for the tricycle, it is similar to the principle of the bicycle, except that the bicycle has two wheels, and the tricycle has three wheels.

However, tricycles can carry more people and more goods. Compared with single-person use of bicycles, tricycles can be used for family use, or for transporting goods in shops.

Of course, whether it is a bicycle or a tricycle, it can only be used as a means of transportation in a small area, and the travel area is very limited.

The number of people or cargo carried is also very limited, and it is impossible to transport a large number of people and bulk cargo, and the scope of transportation is also limited.

At this time, trains and ships are needed!

A train is a train powered by a steam engine.

Everyone is familiar with the steam engine, as long as you add coal to it, boil water continuously, and use the steam to drive it, you can keep running.

Unlike livestock, which need rest.

And the driving power is also stronger than that of livestock, I don't know how many times!

It can be said that as long as the train track is repaired wherever it is, the train can run there with a car full of people or goods!

As long as the coal is unceasing, you can keep running and running, 24 hours without stopping!

This kind of efficiency and speed can satisfy his business plan after traveling through the past!

The difficulty of the train is on the steam engine.

As for the steam engine, he had learned it when he was in school, and he is still very clear about the basic principles of the steam engine.

The core principle is that steam pushes the piston to reciprocate through thermal expansion and contraction, and converts heat energy into kinetic energy.

He saw on the Internet that many people have made some small mini steam engines by themselves.

After traveling through the past, he organized a group of people to study it, and it would not be a big problem to make a steam engine!

Chapter 24 Everyone's advice is too conservative!

As for the train tracks, that would be a better solution.

After he travels through the past, Datang's steel production will definitely explode in a revolutionary way!

There will definitely be enough steel to lay the train tracks by then.

Moreover, it is definitely impossible for him to have trains all over the country like modern times.

The manpower, material and financial resources consumed in that way are too great!

And the time will definitely be very long, even he probably can't afford it.

So his prediction is that it only needs to lay a few main roads from north to south and from west to east.

As for the follow-up track, it will be decided in the future depending on the situation!

Moreover, even if there are only a few main roads from north to south and from west to east, as long as the train starts to run, it will be a subversive improvement to Datang's transportation!

The means of transportation on land is the train, and the means of transportation on the water is the ship.

The steam engine can be used as the power source of the train, so it can also be used as the power source of the ship!

With the steam engine as the power source, there is no need to rely on sails to drive the ship, which undoubtedly frees the ship from relying on the weather.

The wind in the inland river is definitely not as strong as the sea, so when the ship sails on the inland river, the wind will drive very, very slowly, which will undoubtedly greatly reduce the efficiency of transportation!

Sometimes when there is no wind at all, if you don't use oars, the boat will just stay still on the water, which is obviously impossible.

But if a steam engine is installed on the ship, and the steam engine is used as the power source of the ship, then there is no need to look at the weather at all.

Regardless of whether it is windy or not, as long as coal is added to boil water, the ship will sail forward without stopping.

And the speed is very fast!

In this way, we can make full use of our country's developed Yangtze River system and the Grand Canal, and revitalize the traffic in the Yangtze River Basin and both sides of the canal!

The most important thing is that once the steamship is manufactured, it means that he can form an ocean-going fleet!

The ocean-going fleet can ride the wind and waves and sail all the way to all continents!

At that time, whether it is to do business, go there to find crops that the Tang Dynasty does not have, or use them for war in the future, it will be very critical!

However, in addition to manufacturing and producing more modern means of transportation, the original means of transportation in ancient times can also be optimized and improved.

For example, in the army, or nobles and wealthy families, families that can raise horses generally use horses as a means of transportation for riding.

However, due to the times, some tools for riding horses have not been created.

In other words, it has already appeared, but due to various reasons, it has not been promoted.

Such as riding a three-piece suit, stirrups, saddles and horseshoes!

Stirrups, as the name suggests, are places for stepping on your feet.

Although it is such a simple function, it can actually improve the stability of people sitting on horseback extremely effectively!

A saddle is equivalent to a seat that prevents the horse from being on the back, mainly to improve the comfort of the person sitting on the horse.

As for the horseshoe, it is nailed to the horse's hoof.

The reason why horseshoes are nailed to the soles of a horse is the same as why people wear shoes.

If you walk barefoot on soft ground, you may not feel pain.

But if you run on a gravel road, the soles of your feet will definitely hurt.

The same is true for the soles of the horse's feet. Running on the grassland is definitely no problem, but in the plains, the road surface is very hard, and long-term running will wear off the horniness of the soles of the feet, which is equivalent to wearing off human nails.

Without the protection of horniness, the soles of the horse's feet are like feet without shoes, and naturally they cannot run at high intensity.

At this time, it is necessary to nail a horseshoe on the horniness of the horseshoe, which is equivalent to wearing a pair of shoes for the horse!

In this way, you can run freely, whether it is on a hard road or a gravel-covered interior, you can run casually!

Of course, these three-piece suits are just easier for ordinary people to ride a horse.

But the true power of this three-piece suit can only be maximized on the cavalry.

A cavalry equipped with a three-piece suit faces a cavalry without a three-piece suit. If the riding skills and combat effectiveness of both sides are equal, the one equipped with the three-piece suit must win!

And the process of the battle is absolutely one-sided massacre!

This is the power of the three-piece suit!

He picked up a pen, and started to record on this page of 'line'.

'Bicycle Design Drawings and Crafts', 'Tricycle Drawings', 'Train Design Drawings and Crafts', 'Ship Design Drawings and Crafts', 'Steam Engine Design Drawings and Crafts', 'Right away three-piece set'.

After recording, he rechecked and reviewed everyone's replies to see if there was anything missing.

After reading it, although I didn't find anything missing, I found that everyone's thoughts and suggestions about "going" are a bit too rational and conservative!

Well, very conservative indeed!

They didn't even suggest that Li Ke get out the planes and cars after traveling through the past. This is not like everyone's style.

However, there is still a little hope for the car. At least a simple version of the car should be able to be produced in one's lifetime.

But the plane, he really didn't hold out much hope.

Because the aircraft is too complicated, with too many and complicated internal parts, and the production and processing are difficult, and the material requirements are also very high.

Especially airplanes need the theoretical support of aerodynamics very much, this thing is very difficult!

Mr. Qian was the top aerodynamics expert in the world back then, and it was because Mr. Qian, the top aerodynamics expert, returned to China that he would have great success in the aerospace field!

Anyway, he doesn't understand. Even if he goes to learn now, there are less than two months left, and he probably can learn a little bit.

And the difference between airplanes and cars is that cars run on the ground, and if something goes wrong, you can get out of the car to avoid danger.

But the plane flies in the sky, once something goes wrong, what will the person do?

It is estimated that everyone also knows that flying is too difficult, so they simply did not mention it in the suggestion.

"Although it is very difficult, but anyway, let's simply understand it before crossing."

"Even if it can't be manufactured in a short time, it can be regarded as laying some foundations for future generations!"

Li Ke thought about it, and added 'car' and 'aircraft' in his notebook.

PS: Please collect it!Ask for flowers!Ask for an evaluation ticket!

Miss Chapter 25, you don’t want to use it without cosmetics, do you?

He only needs to memorize things in the general direction.

For example, the principle of the internal combustion engine of a car, the principle of an aircraft engine, and so on.

In fact, the principle is really not difficult, I learned it when I was in school, but the real difficulty is the material!

But this thing can be done according to fate. After traveling to the past, he cultivated a group of professionals, and then told them these principles, and let them study by themselves.

What is the final research, it is what it is.

Now that we've finished discussing the topic of 'walking', it's time for the last category of basic necessities of life!

'use'!

The so-called "use" actually refers to some things that need to be used in daily life.

These things may not be necessary, but if they are, they are definitely the best.

"Finally it's the 'use' link, I can finally participate in the discussion, the front is my knowledge blind spot!"

"As a person who loves wine, I can tell the host responsibly that the ancient wine culture is more than ten times stronger than it is now, and the host can definitely make a lot of money by making high-quality wine!"

"Indeed, the alcohol content in the Tang Dynasty was too low. It probably tastes like beer, not exciting enough!"

"Otherwise, you think that the ancient soldiers could go into battle with a clear head and kill the enemy after drinking several large bowls of liquor before going out to battle. If you change to high-grade liquor, you can drink a bowl and pour it down!"

"It's hard to understand that people in the Tang Dynasty drank tea with such a strong taste, but the alcohol they drank was so low!"

"That's because the technology is not up to the mark. People in the Tang Dynasty don't understand distillation technology, so the landlord can monopolize the high-quality wine business!"

"Koji and brewing techniques are also important."

As soon as this topic came up, many people who love wine immediately stepped forward and asked Li Ke to produce distilled wine in the Tang Dynasty.

“Distilled spirits do work!”

Li Ke agrees with everyone's views.

China's current wine culture is inherited from ancient times.

And the ancient wine culture is more than ten times stronger than the current one!
