Rule the Roost in the Tang Dynasty: Five hundred and fifty-eight map two

Li Hong looked at Long Ma regarded as treasures, and continued to draw on the map he had temporarily embracing his feet, carefully smoothing the wrinkles on it, and he was full of respect and admiration for this generation of queens in history. heart.

He knows better than anyone, how shocking she is when such a map appears in Wu Mei's eyes.

After all, the maps of this period are all maps made based on mountains and rivers. The county maps and city maps first draw the center of the city, and then the mountains and rivers, rivers and other places in the jurisdiction. , Draw it according to the approximate location of the corresponding city center, and finally fill in the nearby villages and other places to the corresponding mountain foot and river side, forming a regional map.

Such a map is drawn step by step with simple orienting equipment and simple ranging equipment. Due to the lack of positioning technology and no coordinate system such as latitude and longitude, The error of the drawn map will increase with the increase of the map, and the area is not in proportion to the area. As a result, people can only follow the map as if they are being led forward. If not, then Will be lost and don't know where he is.

As for places with complex forms such as mountainous areas, this type of map is even less useful. Therefore, at this time, the manipulation of the sand table is extremely important in the military, and it is more popular than the unreliable map. The welcome of the generals.

As for the current waterway map, with the increasing importance of the Sui and Tang canals in this period, the waterway map drawn by the Tang people is the mapper standing on the bow of the ship, first drawing Luoyang at this end, and then following the ship. As they progressed, the painter drew down the cities, mountains and rivers they saw along the route. After arriving in Hangzhou, he painted Hangzhou at the end of the drawn map, and then this waterway map came into being.

This kind of map does not have any practical reference function, it is exactly like a mapper who has played around and drew what he saw and heard.

There is no direction and proportions at all. If you are in a good mood, you can paint this place better. If you are in a bad mood, you can draw a few fewer strokes of this place. The maps you make are more like artistic paintings than It is a professional map.

When Li Hong was ten years old, he once instigated Li Chunfeng. The astronomical telescope made for Li Chunfeng at that time made Li Chunfeng crazy for a year. Every day, he had to rely on the telescope for food and housing.

At the same time, the students of Hongwenguan began to adopt the "six-body cartography" made by "Jili drawing method" and Pei Xiu of the Jin dynasty, and began to redraw the map of Chang'an City, but the real coordinates were missing The accuracy of the system and the latitude and longitude, as well as the fact that the curvature of the earth has not been considered, or is not known at all, Hongwen Pavilion has drawn a map of Chang'an for a long time.

It's just that map. Except for the nearby places such as the imperial city, which are more accurate, other places more outside are no longer accurate.

What’s more terrible is that in the process of drawing, they found that the further out the map became more deformed, and even became distorted like it was pulled away by something, and they couldn’t draw a satisfactory map. .

Fortunately, the students at Hongwenguan didn’t feel discouraged because of this. Seeing the prince’s dismissive look, these people were full of energy and began to plunge in. According to legend, Dayu stayed behind when he controlled the water. ："Left standard, right rule, set four o'clock, to open Kyushu, pass nine roads, Bei Jiuze, and go to Jiushan".

Several books such as "Zhou Pi Sutra" and "Nine Chapters Arithmetic" were borrowed from the Imperial College by the students of Hongwenguan. The Shangguanyi at the time was so scared that they could borrow them, but don’t What's the damage?

Drop in, it is bound to make His Royal Highness look at the students differently, one by one, like a wolf and a tiger, just nodding and saying yes, there is only how to draw a perfect map in your mind, and there is no way to think about Shangguanyi. Be careful.

But fortunately, when Shangguanyi saw those books again, she felt relieved. Fortunately, nothing was damaged. There was only one book on it, obviously in the handwriting of His Royal Highness, with four words: " A bunch of fools!"

When these Hongwenguan students, one by one like a rooster that failed in a fight, drooped their heads to see Li Hong, they saw a round wooden ball placed in front of His Royal Highness.

Holding a piece of paper in his hand, I wrote some words that no one could understand: "Jianyi", "High Table", "Yangyi", "Liyunyi", "Xuanzhengyi", Some inexplicable words such as "Zuo Zhengyi" were handed to a student at Hongwenguan.

From these observations over time, Li Hong personally selected more than a dozen Hongwenguan students and asked them to take the piece of paper and the wooden ball to Li Chunfeng, and agreed that within ten years, If you can thoroughly understand and draw a satisfactory map, everyone will be named a Datang official of the fifth grade!

This promise made the students overjoyed, but when they heard that the Prince said that it was ten years later, everyone realized that this drawing of a map was by no means as simple as his own research during this period of time. .

When they came to Taiyi Mountain with paper and the wooden ball, and gave everything in their hands to Li Chunfeng, Li Chunfeng looked at it for a long time, but didn't understand it.

Yuan Tiangang took the ball and looked around, teasing the students: "Who painted on this? What is this?"

But when he continued to turn inadvertently in his hand, he saw a place on the sphere on which the picture was not like a picture or a picture, and when the word Chang'an was written impressively, he was so frightened that refreshment threw the ball. To the ground!

Li Chunfeng, who was startled by Yuan Tiangang’s **** look, curiously picked up the ball and looked at it for a long time. When he muttered the names of places like Chang'an and Luoyang, he suddenly realized that it seemed like a map. !

From that time on, Li Chunfeng led the dozen students and plunged into the map drawing research. From the beginning, he couldn’t figure out why the map was drawn on the sphere. At the end, he was frightened. Looking at the ball shiveringly, everyone's face was filled with fear and disbelief!

Almost at the same time, His Royal Highness, who had already gone to Anxi, suddenly sent a secret letter to Li Chunfeng, and even selected nearly 10,000 people from the six rates of the prince to be driven by Li Chunfeng.

The content of the prince’s secret letter is very simple: "If anyone dares to reveal the truth of the research, there is no mercy!"

At the same time, he naturally told Li Chunfeng that the usefulness of the 10,000 people was that he and the students of Hongwenguan were sent to various places in the Tang Dynasty.

Li Chunfeng was the prince’s secret letter. He and a dozen of Hongwenguan students were locked in a remote palace in Zongsheng Palace for three consecutive days. Until the fourth day, these talents had a firm expression. , Walked out of the palace vigorously and solemnly.

But every one of them cut off their tongues in a palace, and became speechless. No matter how much Yuan Tiangang asked them about their research, these Hongwenguan students seemed deaf and dumb. Similarly, no one paid any attention to his words.

Whether it was Li Chunfeng or the students of Hongwenguan, they were completely shocked by the secret letter of His Royal Highness, and at the same time, they regarded His Royal Highness as a heavenly man in their hearts.

After all, their research is still in the imagination. When they pushed away the clouds and stood on the shoulders of giants and looked down on the mountains and rivers, the shock in their hearts was self-evident: "We actually live on a ball The sun is gone, just ran to the other side of the sphere. The sun appeared because it turned back. The ball under our feet is actually spinning! The stars above are far from what I saw Big, it’s far from being so close to me. The distance between me and them is the distance between life and death."

But in all the celestial phenomena they saw, His Royal Highness did not participate in it. He only occasionally asked how the progress was. He did not participate in the whole process. How did he know that we were on a sphere? And where did you know that the area of ​​the ocean on this sphere is much larger than that of the land!

For three days, Li Chunfeng led the students of Hongwenguan, from doubting life to accepting reality, to dozens or twenty people, forming a circle motionless, staring at the pattern on the wooden ball.

In the end, these dozen or twenty people overcame the fear in their hearts and believed that the world would not suddenly let them fall because of the existence of something called gravity.

Li Hong knows very well that if Li Chunfeng and his research are known to more people, who knows whether the world will suddenly become chaotic, and whether it will be given due to the fact that people live on a sphere. The people of Datang brought fear and panic, and were then used by those who wanted to cause various riots in Datang?

At that time, I really became a sinner of Datang. After all, people's cognition has been left behind in the concept of a round sky.

When they learn that ~IndoMTL.com~ they are living on a spinning ball, who knows if this fact will make them unable to think about it, and think that one day they will fall and fall into the abyss?

So for the sake of Datang Sheji's stability, when he estimated that it was almost the same, Li Hong locked everything firmly in the mouths of more than a dozen people!

From that day on, these talents gradually mastered more subjects such as astronomy, astrology, geometry, mathematics, drawing, and so on. From that day on, their path in front of them completely deviated from the people of this era. He was completely detached from the thinking of this era, and he was living in this field by Li Hong, more than a thousand years in advance!

"Your father told me last night that he now feels that his body is not as good as before, and his energy is getting worse and worse. This time, he realized that he would never be able to surpass the first emperor. He is far behind the first emperor. Originally hoped that this time the imperial conquest would prove that he was in the heyday of the Spring and Autumn Period. Who knows, this time the imperial conquest has completely lost his confidence. I am talking to you, what are you thinking What about Li Hong!" Wu Mei looked up and looked at the map in a daze. He put on Li Hong, who had just closed one eye and made an inexplicable gesture, and was so angry that a feather duster hit Li Hong's again. Shoulders.

"Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh hehhhhhhhhhhhhhed?) been been...this map is not bad?
