Stavrianos says in the General History of the World: "The years from 1500 to 1736 were the period of the beginning of global unification, the transition from regional isolationism of the pre-1500 era to the world hegemony of Europe in the 19th century."

"The world is starting to move towards unity."

"European world hegemony is gradually established."

The Great Voyage, an era that marked the glory of Europe, accompanied by the roar of gunpowder and guns, countless explorers, with technology and tools from the land of China, gradually conquered the world.

Gunpowder, which gave the Western bourgeoisie the weapon to defeat the knightly class.

Papermaking and printing allowed the torch of the Enlightenment and the Renaissance to light up the whole of Europe.

The compass, that is, the compass, carries countless greedy expectations to bring Western civilization to the distance.

But at all times indispensable, there is only one thing.

Map!

Maps have always been a must-have for home travel from ancient times to the present, and you won't have to worry about getting lost when you go to flip through the map and find an iconic thing as a reference.

The Ming also has maps, and they are not all maps.

Just like the map in Li Guanghang's hand, it is like a certain navigation software in later generations, which can guide a person from the avenue to the ditch.

The abstract painting style, the exaggerated scale, the distorted roads, in addition to the main location of the big city and some mountain official roads, other places, not to mention 108,000 li, there are also 120 li.

According to the official statement of the Ming Dynasty, the map that the people on the market can see is deliberately exaggerated by the official in order to prevent the enemy from making details, in order to confuse the enemy, the real standard map is generally a confidential document, and you don't want to take it out without a certain office card, and generally this kind of map, a state capital has a pair is good.

Li Guanghang originally wanted to ask the officials in Suzhou for a picture, but after thinking about it for a while, Li Guanghang gave up this idea.

Leaking military aircraft, this is a big crime that cannot be punished in any dynasty in ancient times, unless you are a treason with an iron heart, and you are sure to wipe out the existing country, otherwise no one will risk the nine clans to commit this taboo.

You have to draw the map yourself.

Li Guanghang is a little lucky, fortunately he is a liberal arts student, geography or something, it is a compulsory subject!

According to the college entrance examination system of later generations, Li Guanghang explored an important method of learning geography - maps.

In later generations, Li Guanghang remembered almost the terrain and landform characteristics of the entire globe, and even if there was no mark, Li Guanghang could accurately describe the local climate and topography and other location factors.

If there is no other reason, except for the climate, there are threats such as global warming in later generations, the terrain and the terrain of the Ming Dynasty at this time should be roughly the same, and there will not be a mountain that does not appear in the later generations.

The corners of Li Guanghang's mouth curled, he picked up a piece of ruler, pressed the rice paper on the table, grinded the ink, dipped it lightly with a wolf hairbrush, hung it lightly on the edge of the inkstone, pulled out the protruding wolf hair, rolled up his sleeves, and waved a big pen.

Brush

The two curves were drawn on rice paper.

These two lines are the dividing lines of the first, second, and third tiers of the geographical division of the People's Republic of China in later generations.

Li Guanghang marked the line on the left side with a brush: Kunlun Mountains - Qilian Mountains - Hengduan Mountains, which is the dividing line between the first and second steps.

Then on the line on the right, it is also marked: Daxing'an Mountains - Taihang Mountains - Wushan - Xuefeng Mountain, which is the dividing line of the second and third steps.

Then, on the basis of the dividing line of the first and second steps, the Qinghai-Tibet Plateau, which was called the roof of the world by later generations, was outlined.

Tanggula Mountains, Gangdis Mountains, Brahmaputra River, Li Guanghang did not forget to mark the world's highest mountain - Mount Everest, and the pure goddess that guards the plateau - the Himalayas.

Call! I don't know how long later, Li Guanghang put down the pen in his hand, and what he saw was a wonderful topographical map of the Qinghai-Tibet Plateau, where every river, every mountain, and even every named ravine was clearly marked one by one.

Tibet has always been an inseparable part of our country, and whether it is now or in the future, Li Guanghang has long had his own blueprint for this place that has not been included in the territory of the Ming Dynasty.

Expanding the territory is not right, it is to regain lost territory.

After taking a sip of the tea that had become cold, Li Guanghang lifted the pen in his hand again and repeated the previous action to rejuvenate the pen.

The tip of the pen came to the northern foot of the Qinghai-Tibet Plateau, which is the Kunlun Mountains, which connects to the largest basin in China, the Tarim Basin. Immediately after that, there are the Tien Shan, then the Junggar Basin, the Altai Mountains.

At this point, Li Guanghang paused, and with his brush, in the northwest of the Junggar Basin, he painted a lake, Lake Balkhash.

I don't know why, Li Guanghang remembered the unforgettable words in the history textbook:

The weak and incompetent Qing government signed several unequal treaties with Tsarist Russia, ceding Russia about two French lands, nearly 1.5 million square kilometers.

Lake Balkhash, the border that generations of Chinese want to touch.

Li Guanghang shook his head, and at the same time his eyes were full of perseverance, the future, the future of the dead, history will be pushed by himself, on the right track.

Then there is the Hexi Corridor, the Mongolian Plateau, the Loess Plateau, the North China Plain, the Northeast Plain, the middle and lower reaches of the Yangtze River Plain, the Sichuan Basin, the Yunnan-Guizhou Plateau, the Southeast Hills, the Hainan Islands, all the way to the Zengmu Dark Sands, then to the treasure island of Taiwan, and then to the Diaoyu Islands. Don't miss one! Don't take one!

Although the painting is not exquisite, but the skillful memory, let Li Guanghang show this picture of the motherland's thousands of miles of rivers and mountains vividly, if Xu Xiake is here, I am afraid it will also be shocking.

Fine-as-fine!

This is probably the only feeling for people in this era.

Because there has never been such a detailed map on the land of China.

If there were already these maps, maybe Xu Da would not have been ambushed in the desert, and Zhu Di, the ancestor of the Ming Dynasty, would not have gone deep into the Ming Dynasty for a hundred miles and not see a single one.

But history is like this, everything is predestined, history will not change because of mercy, it will not regress because of mercy.

So someone will pick up this burden, so that the division of the land will no longer exist, so that the death of the vast people will not happen again, so that the people of the dawn will no longer run, let the world return to the heart, and let the lights shine forever.

History never accommodates anyone, anything, and the inspiration given by history is unparalleled enthusiasm and surging.

It is remembered that General Huo Da stepped through the Helan Mountain for thousands of miles and sealed the wolf; Emperor Ran Min wielded a knife to break through the cage of the Han family, and he was alone for eternity......

History gave him enthusiasm and pride.
