The road map is a bit more complicated than at sea. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

At sea, just care about the change in the horizontal direction.

Although there are ups and downs in the overall sense of direction, for individuals, the feeling does not change much.

But on land, sometimes even if you go diagonally, due to the changes in the scenery around you, you will actually lose the feeling of leaning towards the body.

In addition to the change in the slope of the sea and the slope, there are also changes in the sea.

It is the principle of deflection to the right.

Unless the personal direction clock, such as when the foot is forward, the two feet will have different steps forward. Otherwise, the person will turn to the right.

At sea, this deflection is natural and difficult to correct if there is no road to compare.

If you don't correct your direction, then your direction may be round.

The result of going around in circles at sea is that nothing can stop you, and you are likely to go around in circles at sea and there will be never-ending turns.

In the end, you will feel that you are a ghost hitting the wall, walking countless roads, but you can't get out, the scope of this one view, if you are sensitive enough, you will find that the nearby scenery seems to be the same.

Inadequate. If you are sensitive, you will find that the scenery has not changed.

This feeling can make people feel terrible when there is no direction to contrast, and even make a person go crazy for no reason.

Qian Rujun knew this situation, so every time she set sail, she asked not to rely on intuition, but to constantly measure and measure against the chart.

Sailing against a chart actually feels very strange, because you will feel that the route you take is obviously not upright but crooked, but this crooked method can get you to your destination.

Qian Rujun actually doesn't know much about this kind of navigation technology, she only vaguely knows it, so in order to be able to market correctly, she also specially exchanged it for a skill book.

Maybe he just knew that he needed this kind of technique very much, and this nautical technique book actually had more points than other books.

Qian Rujun really wants to say that e-paper books are pit goods.

Perhaps for e-paper books, navigation technology is also something that should not appear in this era!

But aren't other technical books something that should appear in this era?

Perhaps the e-paper book will judge that if it is not for the deliberate concealment of the technology, the semantic technology will not be able to move forward. Some of the technologies should have existed!

Although the sea is dangerous, it is relatively safe for Qian Rujun most of the time, because no one can compete with him in this era.

Perhaps it can't be said that there is no one, because she knows it, the Great West. Around the Mediterranean, the Greek peninsula, the Italian peninsula, the Iberian peninsula, and the North African region have developed special seafaring techniques.

If this is the case, why do you think that the East has not yet developed navigation?

Qian Rujun thinks that she can't think of things, so she doesn't want to think about it, or obediently change the technical manual of the paper book, use it well, and improve her life!

When Qian Rujun was investigating the situation along the coast at sea, there were actually no robbers and pirates or anything like that.

And only the small boat board that appears on the coast, in the sea, the size of the ship determines the size of the fist, even if you don't know how to fight, hit the boat, the other party only has to admit it. There is no temper of resistance at all.

Therefore, in fact, in the Age of Discovery, the importance of people is getting lower and lower, and more often they rely on ships and gunboats to live, because gunboats have the strength to attack distant places.

It means that he can control the coastal zone, but if he wants to go inland, it still depends on people, because. Even cannons can perform different functions in different hands.

Because there is no one else to stop it, for Qian Rujun, what it needs to consume is actually manpower and time.

You don't need to play hide and seek with others, and you don't need to care about other people's property rights, you can go anywhere.

Therefore, the information of the ocean, Qian Rujun has accumulated and gradually enriched, and now his ships have been surveyed to the mouth of the Yangtze River, and the islands along the coast have almost been investigated by him, and some can be developed and used, and he gradually sent people to occupy them.

However, Qian Rujun has no idea of occupying the southern island for the time being.

Since it used to take a long time to sail, it was too uneconomical to manage those places at the current speed of ships.

There is one more factor, and there is a strong threat on the islands further south, and that is typhoons.

Most of your current construction technology is not able to withstand typhoons, and when the typhoon sweeps away, the house is no longer a place to protect you, but a dangerous place that can crush you at any time.

But when it's windy and rainy outside, you can also be defeated by illness.

Do a good job of typhoon warnings in advance and prepare in advance? At this time, the Qin Tianjian did not yet have the ability to predict typhoons.

In other words, they can only observe the phenomenon and then put it in hindsight, and they are more powerful at the operation of celestial bodies.

At the very least, the appearance of comets and meteors can be observed.

But in this era, when the various ions are not clearly understood, even if you predict meteors and comets, what is the use?

can only drag it to the emperor's body, and take this thing as a warning from heaven.

Speaking of which, it is really unlucky to meet a knowing emperor, obviously it is none of his business, and people have to throw these things on him.

The rule of Wenjing is already an era when all dynasties were more enlightened and better governed.

But there were many celestial changes in this era, so these two emperors had to write a confession to God every day. It's really unlucky.

The situation on land, in fact, there are some official classics and materials in the yamen.

Perhaps it was during this period that things changed relatively little, so many of the official texts are very old. Some of them were sorted out when the Han Dynasty first founded the country...... Old materials from the previous dynasty.

In comparison, the former dynasty or the former dynasty is more serious in making materials.

Perhaps it was in the era of the greatest changes, and the magistrates at that time were more responsible.

It's just that the damage rate of the data is relatively high.

In addition to the reason why the house is made of wood and earth, there is also a relationship between the wars of this era and the fact that they like to burn away the traces of the previous dynasty with fire.

Moreover, even if there is old data, the availability of new data is not high.

Because in this era, if the documents and materials were made by literati, they were too particular about the ornate rhetoric.

In particular, the key figures are either vague or exaggerated.

With three thousand feet of white hair, this kind of exaggerated rhetoric is one of the favorite of the literati.

It seems that if you don't write like this, you can't express the surging of his feelings.
