"Yangquan County! I don't know where you learned all this? Eldest Sun Wuji exclaimed and asked. In his opinion, it is absolutely impossible for ordinary people to know such accurate geographical knowledge and such a wide coverage, but they don't know where Chu Ze came from.

Chu Ze thought for a moment and thought about how to explain this matter, and said, "These are what I saw in some books at home when I was a child, and I also verified them along the way when I was with the army a year ago, and they are basically the same as those recorded in the book. ”

Looking at everyone's hungry wolf-like eyes, Chu Ze knew that everyone wanted to borrow books to see, and without waiting for everyone to speak, Chu Ze sighed and said, "Alas, but then there was a fire at home, and the books handed down from the family were also turned to ashes. ”

After hearing this, everyone sighed incessantly.

His Majesty Li Er knew some of Chu Ze's family background, and he didn't think much about it, his eyes flashed, he looked at Chu Ze, and said, "Chu Ze! How much else do you know about geographical maps? Draw it for me, and if you satisfy me, I will reward you heavily. ”

When Chu Ze heard this, he was overjoyed in his heart, thinking about what reward His Majesty Li Er would give him, isn't it just a hand-drawn map of China, and it's not just a hand-caught one.

"Your Majesty! You ask the minister to bring some paper, the bigger the better, the stronger the better, and the minister can draw it now. Chu Ze said confidently.

His Majesty Li Er gave an order, and several chamberlains were dispatched at the same time, and in a short time, more than a dozen pieces of various fine papers with a length and width were placed in front of Chu Ze.

These papers are the most precious paper in the world, which is the Qingtan rice paper of Jingxian County, Huizhou, with single silk road, double silk road, rib pattern, turtle pattern, etc.

Chu Ze chose a few pieces of tortoise-patterned rice paper, not because of anything else, but because it looked good.

After more than an hour, Chu Ze wiped the sweat on his forehead, thinking that drawing with a brush was slow, thinking that when he was in the military academy professional assessment in the later world, it took more than an hour to draw the map of China by hand. You must know that this is the major of the military academy he studied, which is a graduation assessment subject.

Because there was enough paper, Chu Ze held the idea that being idle was also idle, so he simply put together a few pieces of paper and drew the entire Eurasian continent, but except for the extremely detailed map of China in later generations, the other regions were only roughly drawn. Of course, he will not draw the borders of the future generations on it.

For more than an hour, His Majesty Li Er and the others have been looking at the map drawn by Chu Ze, and they will discuss and confirm each other during this period. But because they had never seen such a complete and detailed map, after comparing it with what they knew in their minds, many doubts arose in their minds.

"It's so big, it can't be the whole world map, right?" Eldest Sun Wuji asked with some uncertainty.

Chu Ze was stunned for a moment and nodded yes.

"Good! Very good! Chu Ze! Well......... Here, and here are all too simple to paint, just like the vicinity of Chang'an, can you paint in detail. His Majesty Li Er looked at the map with two eyes, he knew better than anyone the value of the map drawn by Chu Ze.

You know, since ancient times, marching and fighting, because the terrain is not familiar, how many generals are worried about some terrain?

Because the terrain is not familiar, the army delays the military aircraft, cannot advance quickly, and consumes a lot of manpower and material resources to detect, and it is not necessarily accurate and complete. For example, recently, His Majesty Li Er is preparing to send a large number of spies to reconnoiter the terrain for later expeditions.

But now that there is this map, there is no need to do these things, Datang not only has the upper hand, but also does not have to worry about the exposure of the secret agents and startling the snake. This has an inestimable effect on the outcome of a war.

Chu Ze looked strange and said to His Majesty Li Er: "Your Majesty, the minister has already drawn in detail the places where my Tang Dynasty, Tubo, Turkic, Silla, Goguryeo and other countries, as well as the places where the Dangxiang, Xiqiang, and Zhubu are located. ”

"What! Chu Ze, you circle my Tang Dynasty and mark the various states for me. His Majesty Li Er said in surprise.

Chu Ze thought to himself that thanks to the fact that he had learned about the war history of the Tang Dynasty in detail when he was studying the history of Chinese and foreign wars in the military academy before, he remembered the names of some important cities in the present and future generations, otherwise even if he could draw a map now, he couldn't say the names of some provinces, states, and capitals, which would be funny.

After half a burnt incense, His Majesty Li Er squatted and watched for a long time, and pointed to the small piece of land in the east with an incredulous expression and asked Chu Ze: "My Tang Dynasty is so big?" There are ten provinces in my Datang, nearly 300 states, spanning thousands of miles, and it is actually so big? His Majesty Li Er looked at the world map and was very, very dissatisfied that Datang only occupied a small area.

"I've heard of this big food country, it turns out that in this place, it's really far away from my Datang, are they really that big? And this Byzantine Empire is in the westernmost part and also occupies a lot of territory. However, although the land area of this Kievan Rus' is large, if you look at the map, you can see that it is in the bitter cold land in the north, and the estimated population is not much. His Majesty Li Er's face was solemn and incredulous.

As an emperor who has always regarded the Tang Dynasty as the center of the world and considers himself to be the world's largest power, His Majesty Li Er is dissatisfied with the division of the world to the limit, and a series of questions roared out of his mouth, each of which was naked jealousy. Since becoming the emperor, His Majesty Li Er has not been so out of shape for a long time.

The eldest grandson Wuji, Fang Xuanling and a few others were actually not much better, but because His Majesty Li Er took the lead in losing his temper, they were startled, and they didn't dare to say anything more for a while, so as not to stimulate His Majesty Li Er. It's just that from their ugly faces, it can be seen that the thoughts in their hearts at this time are similar to those of His Majesty Li Er.

Chu Ze sighed secretly in his heart, he didn't expect that drawing the Eurasian continent would bring such a great stimulus to the Tang Dynasty monarchs, thinking that it was fortunate that he didn't draw the seven states, the five oceans, and the whole world, otherwise he might be even more irritated by these turtles in front of him.

"Alas! If it's too far away, I won't talk about it. Take the area around my Datang Dynasty as an example, even if this Western Regions is counted, the vast Siye has long heard of it. Why is the territory occupied by Tibet so large? His Majesty Li Er deserved to be the first emperor of the ages, and soon regained his composure, focusing on the surroundings of the Tang Dynasty, pointing to the Qinghai-Tibet Plateau, and asked with a few clicks.

Chu Ze said: "Your Majesty doesn't know, this land looks big, but most of it is extremely high in altitude, the climate is cold and dry, and even nearly one-third of the place is covered with snow all year round. The living environment is extremely harsh, so the total population of Tubo is equivalent to the population of an ordinary large state in my Datang. The actual land occupied is less than one-tenth of what is shown on the map. ”

His Majesty Li Er nodded, obviously he also knew some about the situation in Tubo, but he didn't expect the Qinghai-Tibet Plateau to be so vast.

Next, His Majesty Li Er looked at the Turkic and party departments in the north in detail for a while, and finally fixed his eyes on Goguryeo, and said: "Here I want to turn it into my Tang Dynasty within the difficulties of my life." ”

The eldest grandson Wuji and the others nodded yes with red eyes.
