In ancient times, maps played a vital role in winning or losing a battle. When Jing Ke assassinated Qin, the stepping stone he took was the map of Yan State. During the Warring States Period, having a map of a country and a city basically
It is the same as occupying.
In the Tang Dynasty, due to the endless wars and divisions in various places for thousands of years, especially after the Three Kingdoms era, there was no longer a distinction between "Qin Land" and "Chu Land", and the map was also kept secret and became one in one part.
It is a "relatively open secret" that is held and circulated in the hands of people, especially military elites. But even so, there are still only a few people who have maps, and the degree of accuracy varies.
An accurate map, in the hands of a skilled general, can play a huge role. For example, if a valley is marked on the map, and the general knows it in advance, he can ambush and set up a "pocket formation" to annihilate all the enemies.
The side using inferior maps did not have this valley on the map, so they were unaware of the ambush and did not even have a chance to resist.
This is only the most obvious effect of an accurate map, and there are many more uses. Li Shimin was born in the military, and when fighting, the map was something that was always with his weapon, always at his left and right.
Li Shimin looked at this map and couldn't help but become fascinated. He stretched out his hand and followed the lines on the map, and found that both the level of sophistication and the marks on this map were better than those he had seen before.
, it should be several levels higher.
Compared with this picture, the map Li Tai drew before is simply garbage!
"What a picture!" Li Shimin couldn't help clasping his hands and laughing. He looked at Empress Changsun and said: "Queen, God has given me Li Mu, who is worth millions of soldiers! I really don't know, is there anything he can't do? Talent,
No, he is a genius!"
Li Tai also looked proud and said: "Yes, father, my eldest brother is a genius!"
Before Empress Changsun could speak, a voice suddenly came from the door: "Qingque, it's rare for you to say good things for me in front of my father... But you are also discerning. You are right, brother, I am a genius.
,Hahaha……"
Li Tai turned around and saw Li Chengqian's proud face. He smiled bitterly and said, "Brother Prince, I'm not talking about you, but our eldest brother, Zhuluhou Li Mu."
"Uh..." Li Chengqian's smile froze on his face, and he was extremely embarrassed. He forced himself to laugh and said: "It doesn't matter, it doesn't matter. My eldest brother is a big genius, and I am a little genius. Although he is great, I am actually not bad lately."
As Li Chengqian was talking, he suddenly saw a map, and his eyes widened in vain: "Where did this come from? Is there such a map in the world?"
Li Shimin smiled and said: "Li Mu painted it. Chengqian, come and take a look. How does it go?"
"Oh my God!" Li Chengqian almost lay on the map, looked at it from top to bottom, left to right, and exclaimed: "Father, I really don't know how my elder brother drew it, this...
…I really can’t think of it.”
When Li Shimin heard this, he also asked: "Qingque, didn't you ask him how he drew it? Or did he refuse to tell?"
"Father..." Li Tai lowered his head and said, "It's not that the eldest brother refuses to speak, but that... the child doesn't understand."
"Don't you understand?" Li Shimin was extremely surprised. Among all his sons, why did he like Li Tai the most? The main reason was not that Li Tai was fat, but that Li Tai was smart. Li Tai was good at reading, calligraphy, arithmetic, and writing.
They are all the best among his sons. As for being obese and unable to practice martial arts, it is not a big problem for Li Shimin, because he has experienced the transition of the Sui and Tang Dynasties and knows that it is easy to conquer a country but difficult to sit on it. You can conquer a country on a horse,
You can't sit on a horse while sitting on a mountain. So if you can't practice martial arts, it's not a problem.
Now Li Tai actually said that he did not understand what Li Mu said. Li Shimin felt that he could not understand it. What kind of theism could reach the level of incomprehension? Li Shimin was very clear about Li Tai's geographical attainments. Compared with
Everyone in this world is no longer weak at all!
Li Taibi measured a circle and said: "Father, my eldest brother said that the ground under your feet is round, so the map should have a certain arc. The map I drew was just short of this arc, but the child couldn't figure it out.
If the sky is round and the earth is round, how can the earth be round?”
"round?"
Li Shimin also compared it and said, "He said it's round?"
"How can it be round..." Empress Changsun was also puzzled and asked: "Li Mu didn't say, why does he think it is round?"
"I gave an example, saying that the water of the Yangtze River rolls eastward and never ends for thousands of years. Why can it not be exhausted? Because the earth is round and the water goes around in a circle and returns to the west, so it will never end. But the child feels,
There seems to be something wrong, but the kid hasn't figured out the reason yet and doesn't dare to argue with his elder brother."
"Is this a statement..." Li Shimin was also confused. He was not good at astronomy and geography, and he couldn't explain it. While he was frowning and thinking about it, he suddenly found that the map in front of him seemed to be moving. When he lowered his head, Li Chengqian
One-third of the map has been rolled up, obviously he wants to steal it!
Li Shimin was furious, slapped the map with one hand, and hit Li Chengqian with another slap on the back of the neck, cursing: "You traitor, how dare you steal my map?"
Li Tai was stunned beside him and said quickly: "Father, this is my son's map!"
Li Shimin was extremely surprised: "Don't you want to dedicate it to me?"
"I never said that I would dedicate it to my father, I just wanted to show it to you."
Li Shimin seemed not to hear clearly and said, "What didn't you say?"
"Dedicated to Father"
"Good son!" Li Shimin rolled up the map and put it in his arms. He patted Li Tai on the shoulder and said, "I will accept your intention. Everyone, please step back. I am tired! Gao Gan, send the prince and the king of Yue to you."
go out."
"..."
"..."
The two brothers looked at each other and came out of the Tai Chi Palace with their heads hanging down. As soon as they left the palace, Li Chengqian couldn't help complaining and said: "Qing Que, do you think you are stupid? My father has been fighting all his life, and it's so nice to see him like this."
How could you not want your map? Next time something like this happens, show it to me. I really won’t take away someone’s favor. I’ll give it back to you after reading it.”
"Heh," Li Tai glanced at Li Chengqian and said angrily: "Brother, I don't believe what you said. Once you bought a halberd in the West Market and you were short of 30 guan. I will lend it to you.
It's been a year and two months now, have you paid me back?"
"Is there such a thing?" Li Chengqian was shocked and laughed: "Oh, look at my brain, I completely forgot about it, hahaha... Don't worry, I'll pay you back another day. I have something else to do, so I'll leave first!"
"Brother Prince! Don't leave. When will the next day be?"
"Another day will be another day. I, your majestic prince, can still pay you back!" The voice became more and more distant. When he heard that he had to pay back the money, Li Chengqian ran so fast that Li Tai, a fat man, would definitely not be able to catch up.
…
In the Taiji Palace, Empress Changsun held Li Zhi who was sleeping again. She couldn't help complaining and said: "Your Majesty, how can you rob the child's things? If you want a map, just ask Li Mu to draw another one."
"You think I want it? If I ask for Qingque's map, Qingque can still go to Li Mu and ask for one. But if I ask Li Mu for it, what will this guy do in exchange if I can't protect it? I'm a little afraid of him now.
I can't scheming against him. Let me settle down for a few days and wait until after the New Year."
"You," Empress Changsun smiled, picked up Li Zhi, and said, "The young slave fell asleep again. I, my concubine, will go back to the Li Zheng Palace first."
"Okay, I'll be there during dinner time."
Li Shimin watched Empress Changsun go out and winked at Eunuch Gao. Eunuch Gao walked to Ji Kuo and whispered something at a sound transmission device. After about a stick of incense had passed, Yuan Tiangang came out of the secret passage.
.
"Your Majesty, what do you have to do to summon me?"
"Look at this map." Li Shimin unfolded the map to Yuan Tiangang and asked, "What do you think?"
Yuan Tiangang's eyes narrowed slightly, he read it carefully and said: "Your Majesty, this is the most accurate map I have ever seen in my life. Who drew it?"
"Li Mu."
"Oh..." Yuan Tiangang suddenly understood, but he didn't see any surprise. It was as if all unexpected things were not surprising as long as they were done by Li Mu.
"I just heard a strange thing. Qingque told me that it was said by Li Mu. He thought that the earth under his feet was a circle. Because he thought it was a circle, the water of the Yangtze River flowed eastward and would never be exhausted, because it would
Go around in a circle and go back... I was confused. You are my Qin Tianjian and you are well versed in astronomy and geography. Do you think what Li Mu said makes sense?"
"This..." Although Yuan Tiangang is a good Taoist priest who claims to be five hundred years old or five hundred years old, he is an ancient man after all. He doesn't know anything about scientific matters. After thinking about it for a long time, he still can't figure it out.
So, suddenly he remembered something and said: "Zhang Heng of the Han Dynasty once wrote "Zhang Heng's Notes on the Armillary Sphere", which said that the sky is like an egg. The celestial body is round like a pellet, and the earth is like the yolk of an egg. It lives alone in the sky, and the sky is huge.
And the earth is small. There is water in the sky, and the sky covering the earth is like a shell covering the yellow. It seems to be similar to what Li Mu said. Since the celestial body can be like an egg, it seems that the earth under our feet can also be like this, but this
These are all conjectures and cannot be verified."
Yuan Tiangang murmured to himself and said: "Even if it is true as Li Mu said, the earth under your feet is a circle...it must be seen from a very high place. How could Li Mu know?"
Li Shimin frowned and continued: "If he is really an immortal, wouldn't that make sense?"
When Eunuch Gao heard this, he laughed and interrupted: "Your Majesty, the so-called banishment of immortals is just a rumor in the market and cannot be believed."
Yuan Tiangang said: "Your Majesty, I am a Taoist priest. Although I have never seen an immortal, there are many seniors who practice immortality and seek Taoism. I also believe in immortals. Whether Li Mu is an immortal or not is not certain. But he has all kinds of miraculous powers.
, if we want to explain it, I’m afraid this is the only reason that can make sense.”
"Well..." Li Shimin was silent for a long time, and then waved his hands. Yuan and Gao both retreated. In the huge Tai Chi Hall, Li Shimin was the only one sitting blankly, wondering what he was thinking.
