As soon as Wei Renshi went back, he immediately went into the study, asked Xi'er to help him cut a large piece of silk cloth, spread it on the ground, and then drew it carefully with a pen.

Not bragging, Wei Renshi is still quite confident in his ability to draw maps. When I was in high school, I studied liberal arts, and the geography teacher didn't need to look at the map at all, and drew it directly on the blackboard with chalk, which was not even bad with the map in the book. Wei Renshi is very good at comprehensive learning, making up for the shortcomings of mathematics and English. Geography is not bad, and later when teaching, I used this ability to show off in front of the teacher who taught geography.

The world is very big, and Datang is actually very small.

Using all kinds of knowledge and opportunities brought by himself from later generations as a golden finger, whether it can become a fulcrum and let Datang pry the whole world is an uncertain proposition.

But Wei Renshi was willing to give it a try. Otherwise, my heart will always be unwilling.

Maybe this is just the ambition of a willful idealist, but Wei Renshi is willing to give it a try.

It took one night to draw a detailed map of the world from Wei Renshi's pen in as much detail as he could.

After printing and drawing another copy of the map and putting it in his locked box, Wei Renshi left the house with the other copy and went to the Wei State Mansion.

When he arrived at the Wei Mansion, Jia Tan heard that Wei Renshi had come with a map, and he was very happy and immediately invited Wei Renshi to the study.

"Nephew Wei Xian, where is the map?" Jia Tan asked hurriedly.

Wei Renshi took out the wooden box, took a deep breath, and took out the contents with both hands.

Jia Tan was full of anticipation, and saw Wei Renshi take a few steps back, grabbed the silk cloth, shook his hands vigorously, and the silk cloth unfolded, and there was a silk cloth nearly a zhang long and wide, and it was spread out in front of Jia Tan.

That's a map!

What is painted on it is something that Jia Tan has never seen!

The lines are winding, and the marks are densely packed.

Suddenly, Jia Tan saw a word, his heart twitched, and his eyes suddenly froze!

Tang Dynasty!

There are some zigzag red lines around it that outline its shape.

Datang! This world, which has all the seas and all directions in his eyes, is not even a tenth of the points on this map!

He has drawn a map of the four seas and knows that the Tang Dynasty is not too big compared to the world.

Can Datang ...... It's so ...... Small?

"This ...... Wei Xian's nephew, this ......" Jia Tan lost his mind in surprise, he never knew, never thought that outside of Datang, there was such a vast knowledge.

Wei Renshi looked at Jia Tan, believing that his surprise and surprise at the moment and this panic were probably unprecedented in his life.

Wei Renshi waited quietly for Jia Tan, waiting for him to calm down and recover from this shock and confusion. He was not surprised by Jia Tan's reaction in the slightest. In an era when the land under his feet was almost the whole world, Wei Renshi knew very well the shock of a person after seeing the whole world.

Even Jia Tan, who has drawn overseas maps, is no exception.

It was no longer a shock, but a subversion and reshaping of its worldview.

It's been a long time, it's been a long time, and it's been so long that the sun outside has reached the right point.

"Wei Xian's nephew......" Jia Tan seemed to swallow a mouthful of saliva with difficulty before he spoke: "Is it possible...... Explain one or two to the old man......"

"Good! Duke Wei, please look, this is our Datang, which is considered to be a few capital protectors, and our Datang actually occupies so much land under the world. To here, here is the Tibetans, and above here are the Uighurs. This is the Western Regions...... This is the Great Food ......" Wei Renshi lowered his head to identify on the map, and said to Jia Tan: "Further west, this is the ...... of the forest."

"To the northeast, here is the Bohai Kingdom, and further north, it is a land of ice and snow, but the area is huge, more than two Datang! Further northeast, there is the country of ghosts and the country of Yakshas. In winter, if you travel from the Yaksha Country, you can cross the frozen strait here and reach this land. It's borderland......"

Wei Renshi explained this map to Jia Tan in detail.

After a long time, Jia Tan stared at the map, still couldn't close his mouth and sighed, and said in surprise: "There is a cloud in "Zhuangzi": The well frog can't talk to the sea, and he is confined to nothing. Why don't you be like a frog at the bottom of a well, sitting in a well and watching the sky! Just drew a map of Huayi in the sea, and thought that he had painted most of the world, but he didn't know that there were so many places! Today's old man is really an eye-opener! ”

After that, Jia Tan shook his head with a wry smile, and said: "The old man is quite complacent about his own drawing of the four maps in the sea, and today I know that it is just a class to get an axe, which is really ridiculous and generous!" ”

"Where is the Duke of Wei, the map in the hands of the little nephew is only a general map, although it covers a wide range, but for a single place, it is not too detailed, and because this is a summary of countless people in the past dynasties, it is also possible that the place names on the map have changed, and it is not known. The Wei Gong's "Map of Hainai Huayi" records in detail the unification of the Tang Dynasty, including the history of the Tang Dynasty's territory, administrative divisions, ancient and modern counties, names of mountains and rivers, directions, and transportation roads. The place names in the map are ancient and modern and noteworthy, the ancient place names are in black, the current place names are in red, the mountains and rivers of the Ming Nine Domains, the customs of the five directions, the customs of the Yi descendants, the dangers of the mountains and rivers, the history of the past dynasties, the reasons for the abolition of the hundred kings, the reason for the closure of the Tongsai, the difference between the prosperity and decline of the pastoral, the quasi-dense road, to enjoy the number of sacrifices, gather rice and paint sand, become in the palm of your hand, the deification of the Fu Danqing, the compilation of the narrative, but it is more practical. Wei Renshi hurriedly said.

Wei Renshi's words are not sycophants, but the truth from the heart.

Jia Tan's "Map of the Four Empires of the Sea" inherited and developed the method of scientific cartography, and the geographical description in the book was an important basis for China's declaration of territory and sea power to the outside world. He took advantage of the convenience of being in charge of receiving foreign envoys to inquire about the situation of mountains and rivers, geographical evolution, and customs of various countries, and then sorted them out by category. In addition, the merchants engaged in trade activities, the widows of ethnic minorities, and even the rumors and proverbs circulated among the people, he would pay attention to the records, and then absorb the essence, remove the false and retain the true, and spent more than 30 years to finally become this picture - don't Zhangfu left, lay the mountains and rivers; Shrink the four poles in the fiber, and divide the county into paintings. Although the universe is wide, it is not comfortable; The boat and car are passable, and the view is salty - detailed as this.

"The virtuous nephew praised it!" Jia Tan could feel the sincerity of Wei Renshi's words, so he smiled and said, "The old man doesn't dare to be it!" The virtuous nephew can pass on this map, and I think the virtuous nephew must be more familiar with geography. In the future, I can have a lot of contact with the old man. ”

"I want it!" Wei Ren gave a salute: "Little nephew, thank you Duke Wei!" ”
