His Majesty Li Er's tense face finally showed a smile and said, "Since you listened to it, let's talk about it, why do you think Li Gang is stupid to read?" ”

Wei Yan smiled embarrassedly and said, "Your Majesty, do you have a map?" Let's point to the map. ”

"It's fine."

Take the guard to the side hall with a map, this map is big, and it is an eye-opener. However, it is also difficult to understand the eye-opening. The current map, there is no longitude, latitude said, Wei Yan around the whole map three times, compared the memory of the map of China, as well as the early Tang Dynasty territory map seen on the Internet, looking for familiar place names, finally see the clue.

After sorting out his thoughts, he said: "Your Majesty, in fact, the minister doesn't understand very much, it's just that on the side of the couch, how can you allow others to sleep soundly, Tubo is so close to my Tang Dynasty, and now it's okay, Tubo Zanpu has not been established for a long time, and there are still some small tribes that have not been unified, busy with the country, and have no time to look eastward, but, as time goes by, it will become a big trouble for my Datang henchmen." ”

Wei Yan thought about it, asked His Majesty Li Er to take a large piece of paper, drew the map in his memory, and said with a smile: "Your Majesty, the ministers have come back all the way, and they have heard a lot of things and seen a lot, so the ministers will tell you about what they have seen and heard along the way." ”

"Tubo is a new country that has only been founded recently, its founder, is now Zampu Songtsen Gampo, this person is a young hero, when he was thirteen years old, his father, the predecessor Zampu was poisoned by the enemy, he inherited the position of Zampu, trained the army, avenged his father, and gradually unified the country, Dingdu Luo, and established a unified and powerful country. But as far as the current national conditions of Tibet are concerned, the combat power is there, and the national strength is definitely not comparable to my Datang. ”

What do you mean by that? In detail. ”

"Yes, Your Majesty. Your Majesty, please see, the geographical location of Tibet, Tubo is located on the plateau, the terrain is extremely high, the territory is full of lofty mountains and mountains, the snow does not melt all year round, strictly speaking, there are only three seasons of winter, spring and autumn throughout the year, there is no real summer at all, it is cold, arid, and the living conditions are bad, it can be said that it is a real land of poor mountains and bad waters. Speaking from his own profession, in terms of agriculture, the farming methods are backward and the environment is harsh, so he can only grow cold-tolerant and drought-tolerant crops, a kind of barley crop, which cannot be compared with the abundant products of my Datang. But in such an environment, the exercise of the human body is great, after the Tubo people come down from the plateau, they are generally stronger and stronger than the Central Plains people, and if I go up from the Tang people, it is just the opposite, first of all, there is a disease called mountain sickness, which is the first problem faced by our Tang army. ”

Speaking of which, Wei Yan explained to His Majesty Li Er what alpine reaction is. What atmospheric pressure, thin air or something, these professional terms are not easy to explain, and Wei Yan has to say that it is angry.

"The higher the place, the thinner the qi, the more difficult it is for people to survive, and the lower the place, the more qi, the easier it is for people to survive. People who are used to living in low places will have a lot of uncomfortable symptoms when they go up to the plateau, which is mountain sickness. ”

"In addition to altitude sickness, there is also the problem of snow blindness."

"What is snow blindness?"

"When the sun shines on the snow, it forms a strong reflection, and when people look at it, their eyes will be tearful, afraid of light, and temporarily lose the ability to see, which is also a kind of mountain sickness. In Tibet, there are many snow-capped mountains, and the daily sunshine hours are longer than those in the Central Plains, even the Tubo people dare not look directly at the snow under the sun. ”

"In this way, aren't the Tubo people invincible?"

"Definitely. Our army can't attack Tibet, but if Tibet wants to attack our Tang Dynasty, there is also a problem of habit, that is, the people of Tibet are afraid of heat. They live in a cold place all year round, and they are used to wearing fur fur and thick clothes, even if they want to start with my Datang, they will only choose the season when the weather is cool. And our army, as long as it does not go to the plateau, with the military strength of our Tang Dynasty, Tubo is not to be afraid. ”

"In the minister's opinion, Tubo is not currently a threat to the Tang Dynasty, and the threat to our Datang is not them, but it can be slowly figured out. As for how to draw, it depends on the planning of Your Majesty and your adults, the minister is not good at this aspect, however, there is a saying, fighting a snake and hitting seven inches, the minister thinks that you can start with the agriculture of Tibet, and you will die of hunger, Your Majesty. ”

That's all for Wei Yan. He had been following the history of the early Tang Dynasty for a while. His Majesty Li Er, Taizong of the Tang Dynasty, is a very ******** emperor, with his wisdom and wisdom, Wei Yan believes that after saying so much, His Majesty Li Er must have his own judgment in his heart, and he doesn't need to say more.

After talking about Tibet, His Majesty Li Er was obviously very interested in the route of Wei Yan's return, and then asked about the situation in the surrounding countries. Wei Yan's efforts to recall the historical records show that the countries around the Tang Dynasty are not a problem except that Tubo can't beat them. If he hadn't been scared by His Majesty Li Er, how could the countries of the Western Regions give him the title of Heavenly Khan.

Trying to recall the current situation of the West Asian countries, at present, the Tang Dynasty is still the first power in the East, and now we should pay attention to the long-term strategy.

His Majesty Li Er walked around the map twice and said: "What Ziyue said coincides with me, and now that I have listened to your introduction to Tubo, I am even more determined." The threat of my Datang is now in the north, not in the south. However, you can't blindly be gentle, you should have the demeanor and majesty of a great country, and you can't lack the same, if you are obedient, I will follow him, and if you are disobedient, I will beat him hard! ”

Wei Yan had an idea and said, "Your Majesty, I don't know if you have heard of the carrot and stick strategy?" ”

"What? What is the Carrot Strategy? ”

His Majesty Li Er looked confused. Wei Yan waited for his question, explaining: "Your Majesty, carrots, are a home-cooked vegetable in the West, orange-red, sweet and crunchy. There is a country called the United States in the West, in foreign exchanges, like to adopt a strategy, first hit and then reward, Westerners image called this strategy carrot and stick strategy, that is, we Tang people say a slap, and then reward a sweet date, the minister thinks, for Tubo, Nanzhao, the Western Regions countries, you can try. ”

The more Wei Yan spoke, the quieter he became, because His Majesty Li Er's gaze at him made his heart tremble, and cold sweat slid down his forehead, and he laughed dryly.

His Majesty Li Er glanced at Wei Yan deeply, and said in a deep voice: "Wei Yan, you say, you don't understand this?" ”

Wei Yan was very innocent, and said: "Your Majesty, the minister doesn't understand, it's just that every young person has a lot of blood, and when he fantasizes about going to the battlefield, being a general, and marrying a beauty, the minister also had this kind of stage, and then he was beaten by the master with a big stick, but although he didn't go to the battlefield, he read a lot of books, but we haven't operated in practice. ”

"You, you!"

His Majesty Li Er pointed at Wei Yan and shook his finger, and Wei Yan smiled and scratched his head. His Majesty Li Er touched his beard and said leisurely: "History makes people wise, poetry makes people skillful, arithmetic makes people sophisticated, philosophy makes people profound, ethics makes people dignified, and logical rhetoric makes people good at argumentation." How much have you learned about these things? ”
