The final issue is orientation and communication.

Positioning, as the name suggests, is to determine the location of a person or object.

The positioning of ancient people was very backward, and before the compass came out, people could only use the rising sun and the Big Dipper to determine their position.

Although the Tang Dynasty already had a compass, the appearance of the compass did make it easier for people to discern the direction.

However, due to the backwardness of science and technology, the ancient compass could only determine the general direction, nothing more.

But don't forget, the difference is a thousand miles.

Even if it is only a little bit of direction at the beginning, it will be dozens or even hundreds of miles away from the original destination in the end!

There are many scholars and literati who went to Beijing to take the exam, and they spent several years, and they didn't even see the gate of the capital!

The reason is because they are going in the wrong direction, or more directly, they are going the wrong way.

As for communication, it's about connecting with people.

As for why Ningbei put communication in the direction of 'line'.

It is because Ningbei felt that ancient communications also needed to be passed with the help of manpower, so it should not be a big problem to blame them together.

In modern times, with the power of the Internet, communication is naturally a simple matter.

If you want to connect with a friend, all you need to do is send a message and they will receive it immediately.

Where to go? Send the location directly, and the other party can arrive immediately.

But in ancient times, communication was far from so convenient!

Ancient communication can even be described as backward.

In ancient times, if people wanted to connect with their friends, they had to rely on manpower in addition to doing it themselves.

Write a letter and send someone to ride over.

Putting aside a series of risks, it will take more than ten days or even a month or two just to travel!

Even if you successfully hand the letter to the other party, it will take the same amount of time to wait until the other party replies to the letter!

One back and forth, a short one or two months, as long as half a year.

Even the most urgent eight-hundred-mile urgent document would take three to five days to reach the court.

Even if there is any most urgent news, when it reaches the emperor's ears, not to mention that the daylilies are cold, they may already stink......

Although carrier pigeons were also available in ancient times, they were usually only available to official royalty.

And the amount of money and material resources that it takes to raise a pigeon that can send a message is very conceivable.

In addition, the risk of using carrier pigeons is too high, and when passing through the mountains and jungles, you may be shot by hunters, and you may also be attacked by natural enemies.

So after all, it's better to let people hurry up!

But even then, the speed of information delivery is still too slow!

It's so slow that modern people find it incredible.

Although determined to solve this problem.

But how to solve it, how to solve it, and how to solve it, this is the problem that gives Ningbei a headache.

Modern solutions to positioning and communication problems are naturally simple, and they only need to have a network.

And there are satellites that always locate your location.

But then again, it's a modern thing.

And in ancient times, even cars couldn't be built, so let's not talk about these two black technologies!

Automobiles are the product of the second industrial revolution, while the Internet and satellites are the products of the third scientific and technological revolution!

Even now, the history of the Internet and satellites is only a few decades old.

However, he improved the compass to make the direction it pointed more accurately, which should solve a lot of problems.

It can't be said that the compass is a universal locator, but at least it can keep people from going the wrong way.

At that time, there should be no rumors that scholars have been gone for more than ten years, but they have not yet reached the capital.

But regarding communications, Ningbei really doesn't have any good solutions.

Even the most primitive phone is not so easy to make!

Thinking of this, Ning Bei couldn't help but rub his head.

It's not difficult, but it's definitely a hassle!

In fact, no matter what time of day, travel is not a casual thing! You need to be well prepared.

After all, it has only been more than 200 years since the invention of the train.

And in the beginning, the train was not used to seat people, but to transport goods.

It may not be more than a hundred years before human freedom of travel is truly realized.

Ningbei really doesn't have the confidence to let the people of the Tang Dynasty realize the freedom of travel more than a thousand years in advance!

He is a man, not a god.

Ningbei can only improve the lives of the people of the Tang Dynasty as much as possible, rather than directly allowing them to fast forward a thousand years and become the beneficiaries of modern technology.

After thinking about it, Ningbei wrote cement on the back of the road.

In this way, the problem of the road is solved.

In fact, if you think about it simply, as long as you make a highway, the problem of access is half solved.

Cement paved roads are really much more convenient than dirt roads, whether it is for people to walk or transport goods, it is a lot more convenient.

Even if you are walking on the road on horseback, you can increase your speed a lot.

But when it comes to transportation and positioning communications, Ningbei is really at a loss.

So, he looked at the live broadcast room.

"Friends, if I travel to the Tang Dynasty, what kind of transportation should I make to reduce the time for people to travel?"

"Is there a communication technology that is simpler than making a telephone? I travel back in time to ancient times, and I can't write letters to others every day, right? ”

I believe that the audience in the live broadcast room will definitely give him a satisfactory answer.

After all, there is power in numbers!

The audience in the live broadcast room also fell into deep thought, and it was obvious that they were also seriously thinking about the problems that Ning Bei had thought of.

It has to be said that the questions raised by Ningbei are very challenging.

There were too many limitations in ancient times, there were no talents, no technology, and even many raw materials could not be collected.

Therefore, it is really not easy to meet the requirements of Ningbei in these harsh conditions.

At this moment, most of the audience in the live broadcast room was silent.

Seeing this, Ning Bei also felt a little disappointed, could it be that he couldn't earn money in the direction of travel?

It's really unwilling!

But soon, there was a barrage from a reliable audience.

"If the steam engine still needs time to be made, then I suggest that Beige use a bicycle to make the transition first!"

"Yes, the bike is fast, too! And only two steamed buns are consumed in 100 kilometers, which can be said to be a good assistant for home travel! ”

"It's not that hard to assemble a bike, I've tried!"

"If Beige just wants to transport goods, it doesn't necessarily have to be a train. I remember an old-fashioned mining or railroad truck, right on the rails, which only needed two people to shake back and forth to turn on, and it was not slow, and it could transport goods! ”

"In fact, the production process of the steam engine is not too difficult, Beige, you can search for the original steam engine on Baidu, but the parts are more complicated.

Beige only needs to print a few parts drawings, and then let the ancient craftsmen reproduce these parts, and then you can assemble the steam engine. ”

"A car full of precision parts would have been impossible to build in ancient times, but a train made only with a steam engine was still very good."

"Yes, yes, the initial machine structure is not difficult, if you can't remember the drawings of these machine parts, it's easy to assemble."
