Great Tang’s Talented Little Landlord

When I was in Jiulong County, Li Wangyou secretly scolded himself when he saw the navigation map on Su Changqing’s mobile phone.

In order to get a Nobility Rank for the beauty boss, it is so complicated. In fact, as long as he copies the map in the phone, he is not afraid to blind Li Er’s eyes. Why is it difficult to change the Nobility Rank?

Chinas maps have been drawn in a unique style since ancient times. But I have to say, but from a practical point of view, China’s map can’t be considered fine.

Although as early as in the Western Jin Dynasty, the famous minister Pei Xiu put forward the “six cartography”, which clarified the relationship between map scale, position and distance, but the ancient map of China was due to the reasons of surveying and mapping methods and drawing methods. , Lack of map projection and latitude and longitude measurement, resulting in the map is always not accurate enough.

In fact, this is true not only for China, but also for the Western world.

Even in the Wanli period, the “Kunyu Map of the World” drawn by churchman Ricci from the West has made great progress, but the map is far from accurate in future generations. distance.

This is also normal. After all, in an era without satellite remote sensing and mapping, it was too difficult to rely on manpower to measure the world at that time.

Although the navigation map in Su Changqing’s mobile phone is only a civil map for later generations, in terms of accuracy and accuracy, it is an incredible “God Map” in Great Tang.

After returning to Ch_ng’n, Li Wangyou took the time to redraw a map of Huaxia and its surroundings by means of proportional amplification.

Because this map is intended to be dedicated to Li Er, Li Wangyou made it quite large in order to be shocking enough.

On the white silk cloth that is more than one foot long and half a foot wide, Li Wangyou spent a lot of time to transplant the entire map of Asia.

The reason why he didn’t draw a world map is that he was too lazy to explain that many with Li Er.

Otherwise, Li Er and the others will inevitably become a rare treasure, constantly asking him various questions, such as the distance between North and South America, Europe and Africa across the ocean, how to get there, etc. Kind of problem…As a lazy person, being able to avoid trouble for yourself is the most important thing.

After a huge map of Asia was drawn, Li Wangyou thoughtfully followed the habits of the Tang Dynasty and asked Yan Liben for help. He drew the topography of mountains, rivers, city, etc. on it. Make this huge map more visual impact.

After Yan Liben saw this map, even if he knelt down, there was no doubt that Li Wangyou was the ancestor’s discipline.

Except for Daoist Immortal looking down on the earth from the sky, how can anyone draw this kind of map?

The map of Asia that was drawn by Yan Liben, which appeared to be more and more three-dimensional and intuitive, slowly unfolded in front of the Great Tang officials, and Li Er and the others were shocked and froze on the spot.

In the eyes of the Great Tang monarch, this huge map unfolded before his eyes is simply “Gods Vestige”.

Yan Liben learned sketching from Li Wangyou, and learned the focus perspective from Li Wangyou, so that the mountain range and city drawn are very three-dimensional.

According to Li Wangyou’s instructions, he drew a three-dimensional colorful mountain range, river and city on the map according to the trend of the mountain range. This map is seen in the eyes of everyone, just like in Nine Above Heavens, looking down on the earth.

“This…this is my Country? This is my Great Tang?” Li Er murmured.

Fang Xuanling, Zhangsun Wuji, Gao Shilian, Cheng Yaojin, Yuchi Jingde and the others also looked at the huge map in front of them and were at a loss.

Li Er walked quickly to the huge map, pointed at a magnificent city located in the center of the map, very excited: “Ch_ng’n, this is Ch_ng’n! Ziyou, I can say Wrong?”

Li Wangyou is very doglegged and bowed slightly: “Uncle wise, yes, that is Ch_ng’n!”

He was drawing this map At that time, he deliberately adjusted the position and painted Ch_ng’n in the center of the map.

Needless to say, this is naturally for the flattery of Li Er.

Obviously, Li Wangyou’s thoughts were not in vain. Li Er was very satisfied with this, and his fingers kept walking around on the map.

“This is Luoyang, this is Zhengzhou…This is Taiyuan Mansion, and further up is Goguryeo…Ziyou, is this the topography of Goguryeo?”

“Yes, that’s the case.”

“Ziyou, what does the scale marked on this map mean?” Fang Xuanling asked curiously.

“Duke Fang, this scale refers to the ratio of the section length of this line to the actual length. The map drawn by my nephew has a scale of one to hundreds of thousands. In other words, You can use a ruler to measure the distance between two places on the map and multiply it by hundreds of thousands to get the actual distance between the two places.”

The map drawn by Li Wangyou is quite large, so the scale is also very large.

A distance of one centimeter on the map is equivalent to hundreds of thousand centimeters in reality, which is 1000 meters.

Li Wangyou’s explanation made everyone more shocked.

“Ziyou, what do you mean, this map is exactly the same as the world? The distance between the two places can be calculated from the map? How is this possible?” Gao Shilian immediately shook his head.

Don’t say Gao Shilian doesn’t believe it, all the Great Tang monarchs and ministers don’t believe this.

After all, the maps of China since ancient times are not so accurate.

The map shown by Li Wangyou is shocking to everyone, as if it is ten thousand li Country.

But if you just measure it with a ruler on the map, you can know the distance between the two places. This is a fantasy story.

“If Duke Gao doesn’t believe it, why not make a bet?” Li Wangyou said with a smile.

Gao Shilian has been absent in Ch_ng’n for a long time. Where did you know that Li Wangyou is now in Chang’an City, almost known as the “God of Gamblers”. Even an old hooligan like Cheng Yaojin, as long as he hears Li Wangyou say “make a bet”, he will never take it.

Whoever lets this guy bet against others has never lost.

Even if it is an incredible gambling game, how to not be favored by others, the final winner is Li Wangyou.

Therefore, neither Li Er nor Cheng Yaojin will bet anything with him now.

Gao Shilian was waiting to be nodded, but saw Li Er glaring at Li Wangyou: “Ziyou, you can’t even play with my uncle? Hurry up and tell me clearly, your map is really so accurate? This How is it possible?”

Li Wangyou could only sneer when seeing the “treacherous trick” succeeding, and continued to explain.

“Uncle, Lord, this map is really accurate. Although I dare not say that it is exactly similar to the actual terrain, it is also very accurate. As long as you master the use of the scale, it will be very convenient According to the measurement, the distance between different places.”

Although Cheng Yaojin didn’t dare to bet with Li Wangyou, he still refused to believe what he said.

“Mothafucker, I really don’t believe it! Ziyou, you can use this map to calculate the distance from Ch_ng’n to Taiyuan Mansion! I see if your calculation is correct. “

Li Wangyou smiled and found the tape ruler and measured it on the map.

“Uncle Cheng, Ch_ng’n is a thousand miles away from Taiyuan Mansion in a straight line, and the actual distance is more than 1,400 miles. I wonder if my nephew’s calculation is correct?”

When Li Wangyou drew the map, he naturally didn’t know the actual direction of the Great Tang official road. But in the last ages, the official roads and the main provincial roads of later generations are actually mostly lineages.

In the map he drew, the roads in it were drawn in accordance with the provincial highways of later generations. As for the highway, that naturally doesn’t need to be considered.

As long as the official roads of Great Tang are not much different from the provincial roads of later generations, the distance is basically eight or nine.

Sure enough, after he said this number, Cheng Yaojin and Li Er and the others were really dumbfounded…

(The recent update was not good, but there is a reason. After the submission fee a few days ago, I was stunned to find that the draft fee of last month was cut in half… Hey, the winter of the web is not fake. Although Laolong does not live on the draft fee, the insignificant draft fee is really unaffordable. Heart…but the book Court Eunuch or unfinished should not be possible, Lao Long will continue to write seriously, but the speed is slower that’s all, no wonder you. Finally, I wish you a good Dragon Boat Festival!)
