Capital Datang

Li Shimin was a little surprised. He didn't expect Li Yin to spend so much effort to come up with so many good things to please him, just to change a fief?Zhengzhou is a good place. Among the fiefdoms of many sons, only Li Yin is the closest to Chang'an. Does he have any dissatisfaction?

Thinking of this, Li Shimin's face was a little gloomy. After waving away Yu Wenhu and the guards around him, he took Li Yin for a walk on the martial arts field and asked, "Liulang, the matter of fiefdoms has been decided before, and now everyone is sealed up. The state capital has already started to build the palaces for you and several other princes, and Zhengzhou is in a good location, why do you want to change?"

It is not a simple matter to divide princes into enfeoffments. Leaving aside sacrifices and selection of titles, the state capitals to be confiscated must also make preparations. Therefore, although the enfeoffment has not been officially entrusted, in fact, each prince has long known that he will be enfeoffed. where to go.

"Father, Zhengzhou is indeed a good place. Not only is it a big city, but it is also close to Chang'an. It is convenient for my son to visit you and your mother and concubine at any time. However, my son has his own plan and doesn't want to take care of his father for the rest of his life. Under your wings, the Emperor." Li Yin also put away his usual playful smile and said solemnly.

"Oh? I want to know as a father, what are your plans?" Li Shimin was curious and somewhat disappointed. As a father, he suddenly found that the son in front of him had really grown up, and he no longer wanted to let him come. Arrange everything for yourself, but already have your own ideas and plans.Capital Datang 116

What makes Li Shimin even more rare is that Li Yin dared to boldly point out in front of him that this kind of courage and courage is what he values ​​most. Among other sons, even Li Chengqian, who is the prince, and his favorite Li Chengqian Ty, they are dissatisfied with their arrangement.But no one has ever dared to bring it up.He will only obey and follow his own arrangements. Based on this alone, Li Yin is far better than his brothers.

"Father, my son has something, I want to ask Father to look at it, but this thing is of great importance. Therefore, I want to ask Father to go back to the palace to look at it." When Li Yin was speaking, he couldn't help touching the small box in the sleeve of his robe, Whether Li Shimin can be persuaded depends on this.

Li Shimin was even more curious when he saw Li Yin's rare serious expression, and immediately took Li Yin back to the Hall of Liangyi, and asked everyone to withdraw, leaving only their father and son in the hall.

Li Shimin sat behind the desk, while Li Min stepped forward and stood in front of the desk.He took out a small box from the sleeve of his robe, and after opening it, there was a stack of thick silk cloth inside.Li Yin carefully took out the silk cloth from inside.Then he bowed his hands and said: "Father, please see!"

Li Shimin reached out curiously to take it, opened it and found out.There was actually a strange picture drawn on the silk cloth, the whole figure was like a lantern, on the 'lantern' there were several grotesque patterns drawn here and there, and each pattern was marked with words, saying Asia, Europe, Africa, America, etc., and the blank spaces are written with words such as the Pacific Ocean and the Atlantic Ocean.

Intuitively, Li Shimin thought it was a map, but he searched all the state capitals of the Tang Dynasty, but found no inexplicable names such as Asia and Europe. He even thought about the place names of several surrounding countries, but found Still didn't have any clue, finally he could only raise his head and ask Li Yin: "Liulang, what is painted on this?"

"Father, what you hold in your hand is the whole world!" Li Yin replied pretending to be mysterious.

"The whole world?" Li Shimin frowned, and for a moment he still couldn't understand the meaning of Li Yin's words.

"Father, do you know how big the world we live in is? What is the end of the world? Why does the sun rise from the east and set from the west, and it repeats itself day after day and year after year?" Li Min He asked three questions in one breath. If he wants to convince Li Shimin that this map of the world is real, he must first understand that they live on a sphere, not the round sky that the ancients believed.

Li Shimin didn't expect that Li Yin would discuss this kind of mysterious question with him?It's just that his expression became a little strange, and he asked, "Oh? Then why do you say?"

"That's because we live on a sphere, and..."

"I knew this a long time ago." Before Li Yin could finish speaking, Li Shimin interrupted suddenly, with a look of disappointment on his face.

"Pfft~" Li Yin almost vomited blood. Originally, he had prepared a lot of words, presenting facts and reasoning, intending to open Li Shimin's eyes, but he didn't expect him to know that the earth is round, and it's still a circle. It's a matter of course. Could it be that he also time-traveled?

"Father, how do you know?" Li Yin asked weakly, holding a bunch of words in his heart, he didn't vomit blood, but he also suffered from internal injuries.

"Nonsense, of course I know this. As early as the Warring States Period, the Huntian theory was proposed. Anyone who has read some books, who would not know this?" Li Shimin said angrily. I don't like Li Yin's location, but Li Yin is uneducated and skillful, which makes him, a father, unable to get angry even if he wants to be angry.

"Huntian said!" Li Yin almost slapped himself after hearing it. He had learned it in the textbooks of junior high school in his previous life, but he didn't remember it. What made him even more unexpected was that this theory was spread so widely.Didn't the ancients all love the idea of ​​a round sky and a round place?When did you start playing with such a high-tech thing?

"Cough~, father, what you are talking about is the Huntian theory that the world is as round as a chicken. This kind of theory is actually wrong. Of course, it cannot be said to be completely wrong. The saying that the earth is as round as the yellow of a chicken is still true." Yes, but the sky, the sun, the moon and the stars are not as explained by the Huntian theory..." Although he was shocked by the Huntian theory, Li Yin, as a modern person, of course cannot admit defeat, so he simply started talking about the heliocentric theory and For the nine planets in the solar system, Li Shimin must be stunned by his knowledge anyway, otherwise the following words will not be easy to say.

Li Shimin listened to Li Yin's explanation, and at first he was a little disapproving. After all, the theory of Huntian has been developed for so many years, and many astronomical problems can be explained by the theory of Huntian, but Li Yin said that the theory of Huntian was wrong, which made him I thought Li Yin was lying.However, with what Li Yin said was well-founded and well-founded, even the theory of Huntian couldn't explain the answer, but in the theory put forward by Li Yin, the answer can be easily found.This made Li Shimin a little dumbfounded.He began to listen carefully to Li Yin's explanation, and as he thought deeply, he felt more and more.Li Yin's theory is indeed a step further than the Huntian theory, and it is closer to the essence of the world.

Li Yin spoke dryly, seeing Li Shimin's serious expression.I was also very proud in my heart, I finally calmed down the emperor's father.Picking up Li Shimin's tea 'gudong gudong', he drank a few sips, and then said: "Father, whether it is the heliocentric theory mentioned by Huntian or the son minister, they all admit one thing, that is, the earth we live in is spherical. of."

Speaking of this, Li Yin stretched out his hand and pointed to the very non-standard world map, and said: "Father, please look, this is the whole picture of the sphere we live in. The continents above are land, the blank places are oceans, and The place where our Tang Dynasty is located is this Asia."

Following Li Yin's instructions.Only then did Li Shimin find out.On the largest piece of land in the middle, there are still some very shallow lines marked.Outlined a block of areas, the most eastern part of the most extensive area, which is very consistent with the territory of the Tang Dynasty, and then look around, Tubo, Goguryeo, and the Western Regions can find corresponding locations.

Seeing the whole world for the first time, Li Shimin felt novelty and shock, but when he saw that the territory of Tang Dynasty only accounted for about one-third of the entire Asia, he frowned. Even the entire Tang Dynasty always believed that he was a kingdom of heaven and the largest country in the world, but when he saw this map of the world, Li Shimin realized that the world was so big that just a large piece of land could For seven yuan, Datang only occupied one-third of one piece of land, which made Li Shimin, who always thought that Lao Tzu was the best in the world, a little unacceptable.

Seeing Li Shimin's stunned expression, Li Yin immediately guessed that his self-confident emperor father saw that the world was so vast, and Datang only occupied a small part of it, and his self-esteem was hurt.

So Li Yin hurriedly explained: "Father, you don't think the whole world is so big, but in fact, except for Asia where we are located and Europe next to it, other continents are still in the ignorant period of ignorance, and even the country has not yet appeared. , and in Asia and Europe, there is only one Roman Empire, which is the "Great Qin" in ancient books, that can compare with our Tang Dynasty in terms of economy, politics, and culture."

As Li Yin said, he stretched out his hand and pointed to the Mediterranean area in Europe. In fact, he didn't know the specific area of ​​the Roman Empire, but he knew that it was probably there. However, he knew a little about the history of the Roman Empire, and then said: "In our When China was still in the Qin and Han Dynasties, the Roman Empire was once powerful, but later it split into two countries. Among them, the Western Roman Empire has perished, and its territory has been invaded by others. Now there is only the Eastern Roman Empire, and the situation is very bad. It used to be Invaded by Persia and other neighboring countries and nationalities, now Persia is in decline, but there is another big eclipse in the surrounding area, which not only beats Persia badly, but also has constant friction with the Roman Empire, and sooner or later a big war will break out."

"I know Persia, but what kind of country is Dashi?" Li Shimin listened to Li Yin's explanation, but his eyes became brighter and brighter, especially he was very concerned about the affairs around the Roman Empire, and Dashi was just a few years ago. The establishment has not yet reached Li Shifa's ears.

"I would like to report to my father, Dashi is a very special country. They are based on religion, and they believe in a religion called Islam. The state and religion are integrated in the country, and the military strength is also very strong. It cannot be compared with my Tang Dynasty and Rome, but it is an opponent that is not weaker than the Turks militarily." Li Yin reminded that later generations of Dashi also fought against Datang, but unfortunately due to various unfavorable factors, Datang was defeated. Since then, the right to speak in Central Asia has been lost, and even in the next few dynasties, it has not been able to regain it.

"Hahaha~, the stronger their combat power, the better. After conquering the Central Plains for their father, they destroyed the Turks. Now only Goguryeo and Tubo are the two second-class opponents. I feel that life is boring. There are so many powerful countries in the land, one day, I will definitely lead the army and let them know the sharpness of our Tang Dynasty!" Li Shimin roared proudly, today he got the gunpowder weapon presented by Li Yin, and he returned He was worried that Goguryeo was too weak and would not be able to use it in the future. Unexpectedly, Li Yin immediately found several strong opponents for him.

"Father is so brilliant and powerful, and my son admires him so much!" Seeing Li Shimin's arrogance, Li Yin immediately stepped forward to flatter him, but he secretly smiled in his heart. The Tang Dynasty is still far away from Dashi. I don't know if it will happen in the year of the monkey. Li Shimin thought The wish to fight against the Dashi army is probably a little hanging.

After learning about the situation in Asia, Li Shimin asked about the situation in other continents. This Li Yin didn't know much about the situation in other continents during the Tang Dynasty, so he could only talk about it according to what later generations know. Africa is better. , I can talk about Egypt, and then I talked about black Africans, America talked about Indians, and other continents also talked about human customs, which opened Li Shimin's eyes.

"Liulang, where did you know all this?" After listening to this, Li Shimin suddenly looked at Li Yin suspiciously and asked, these are not poems and songs or invented a few new things, like the astronomy that Li Yin talked about just now. And geography knowledge, if it is not taught by a special person, no matter how smart a person is, it is absolutely impossible to know these things out of thin air.

Li Yin knew that Li Shimin would ask such a question, so he had already thought of a countermeasure, hesitated for a while, and then said: "Father, some time ago, in order to find the formula of glass, I once offered a reward of [-] yuan to a Hu merchant in Chang'an City." According to each other, one of the Hu merchants from Persia presented a Kunlun slave who could make glass, and then let Erchen make the glass. In addition, he also sold the knowledge of astronomy and geography to Erchen. I paid the other party a total of [-] guan, and this map of the world was also drawn under his guidance."

When Li Yin spoke, he made a distressed expression on purpose, as if to show that the two thousand coins he paid were not worth it.What he said was half-truth and half-false, and that Hu merchant did exist, this kind of lie is the most difficult for people to distinguish.And the reason why Li Yin dared to say that was because the Hu businessman had left Chang'an with his whole family to return to Persia more than a month ago after being beaten and threatened by Li Yong, so he was not afraid of Li Shimin calling the Hu businessman to confront him.

"Oh? How could a businessman be so talented?" Li Shimin was still a little skeptical.

"Father, although my son doesn't know the identity of the other party, but judging from the other party's speech and behavior, he is definitely not an ordinary businessman. I originally wanted to recommend him to the father, but he refused to serve in the court. Later, my son I went to look for him again, but found that the other party was no longer there, and I don’t know if he is still in the Tang Dynasty.” Li Min strives for perfection, and it is immoral to portray a money-grubbing businessman as a big hermit who hides in the city. Xian.

"It's a pity, it's my fault that I can't use such a talent!" Li Shimin sighed in disappointment when he heard that the other party was missing. He also knew very well that at the beginning because the price of the reward was a bit high, the censor accused Li Yin of acting extravagantly, and he even reprimanded Li Yin for this.

"Huh? By the way, didn't you just want to talk about why you changed the fiefdom? Why did you switch to the world map?" Li Shimin, who was feeling emotional, suddenly remembered that he was only asking about the world map just now. The reason why Li Yin changed the fief has not yet been said.
