Datang: I was exposed by Princess Changle

The Qin Dynasty at that time was a centralized system above the imperial power.

Qin Shihuang alone controlled the power of major counties and cities across the country.

At that time, people all over the country had to listen to him!

The main purpose of Qin Shihuang's establishment of Chidao was not to transport materials.

It is to facilitate his decrees to be conveyed to various counties and cities as quickly as possible, so as to strengthen his control.

In addition, it is used for him to travel around.

Ministers, common people, and even relatives of the emperor have no right to walk the road.

Daqin's Chidao was built on a flat place, the width of the road was fifty steps, and a tree was planted every three feet, and the sides of the road were thickly rammed with metal cones.

The wonderful ideas discussed by these students also inspired Li Shimin.

Yup!

Why not just go straight down the road?

"Cough cough!"

Lin Xuan couldn't help coughing, and reminded Li Shimin who was eavesdropping behind him.

Hearing this, the students looked back in pairs.

After seeing Li Shimin, the students were startled.

Then, there was the sound of pulling chairs.

"See Your Majesty!"

Lin Xuan was a little helpless, this guy Li Shimin ran over to eat again!

Li Shimin didn't care, and said with a friendly smile, "Okay, there is no need to be so polite in school."

Not polite?

Don't be too polite, I'm afraid you will be unhappy!

"You keep talking, I think your ideas are very interesting."

Li Shimin was also polite, and sat directly on Lin Xuan's seat.

Chapter 271 Everyone Expresses Their Opinions!

Depend on!

Li Shimin, you are really welcome!

Lin Xuan secretly complained about Li Shimin dissatisfied in his heart.

Chidao is very controversial in later generations.

The main argument is similar to railways, with special tracks laid on them.

That's right, the track!

The principle is not much different from the railway tracks of later generations, and it is also a double track, but it is not pulled by steam locomotives, but pulled by horsepower.

Chi Dao is naturally not made of iron, but paved with wood.

The wood used as the track is hard and has been treated with anti-corrosion, and it still exists today.

However, the sleepers were rotten, obviously not treated with anti-corrosion, and the material was not as hard as the rails, but its general appearance could still be seen.

Qin Shihuang's achievements mainly lie in the same writing of books and the same track of cars.

Cars on the same track are exactly the same as the track spacing.

It can be used on ordinary mountain roads, and it is even more like speeding on fast roads.

According to incomplete statistics, there are nine famous Chidao alone!

The longest is more than 900 kilometers!

Think about it, it is not easy to build such a long railway in later generations, let alone the Qin Dynasty.

The human, financial and material resources that went in were simply incalculable.

It was precisely because of this that Daqin's Guozuo was completely exhausted, and finally Qin II died.

Even if Qin Shihuang was alive, he couldn't last long.

After the hot pot feast.

At first the students were still a little cautious, but later they found out that Li Shimin was just eating hot pot and listening to their chats, they completely let go.

"I think it should be a combination of waterway and land transportation. Using this method, the speed is definitely not slow."

Cheng Tong opened his mouth and gave his opinion.

"I think it's better to follow the Chidao. The Chidao has been built for many years, and it's only used to pass government orders. It's too wasteful!"

"Professor Lin said well that everything must be used to the best of its ability. It is absolutely feasible to use the road to transport materials!"

"When transporting supplies, one side goes from the west and the other goes from the east, so what if it collides with someone?"

A gangster jumped out and accused Ma Xiu of being naive.Ma Xiu looked at the other party with contempt.

"Can't you cultivate two ways? One is dedicated to the east, and the other is dedicated to the west."

Hearing this, Lin Xuan almost sprayed the food in Li Shimin's face.

Nima!

This is a talent!

Isn't this the model of highways in later generations?

The corresponding two opposite directions are spaced apart from each other.

Do you want to come up with a traffic law?

Two points will be deducted for pressing the line, and 12 points will be deducted for retrograde?
