The Tang Dynasty's mishandling of Liaodong can be described as the most important strategic mistake of the Tang Dynasty in the past three hundred years.

More than ten years later, after the Tang Dynasty spent a lot of effort to conquer Goguryeo, because the strategic thinking of the entire court was basically the same as Li Daozong's thoughts, the government and the opposition did not regard Liaodong as a treasure land as important as Guanzhong and even the territory within the Great Wall.

Under the short-sightedness of Li Zhi and Li Tao and others, the Tang Dynasty was first encroached upon by Silla to unify the Korean Peninsula, and then Liaodong was also in a state of herding sheep, allowing the romantic growth of the Khitan and Jin tribes, so that the Khitan and Jin (the ancestors of Jin), who endangered the Central Plains in the future, grew to the point of competing for hegemony in the Central Plains.

After the growth of these Liaodong turtles in the Khitan Yao, in order to deal with the threat of Liaodong, the Tang Dynasty turned around and established Fanyang and other Jiedu border towns, which planted a time bomb for the Anshi Rebellion.

Analyzing along this main line, it can be clearly concluded that the outbreak of the Anshi Rebellion had a direct and close impact on the mistakes of the Li Zhi era in the handling of Liaodong.

Li Tai's purpose today is to use the divine assistance sent by the Goguryeo people to the door, not only to achieve his goal of interfering in the court, but also to cut off the hidden dangers of the dynasty for the Tang Dynasty.

"Father, my son wants a map of Liaodong." Li Tai made a small request.

Li Shimin waved his hand, and the chamberlain then found a huge map of Liaodong, and after the map was unfolded and put on the shelf, Li Tai approached the map, and he frowned imperceptibly.

This is a map of the march, with cities, passes, rivers and mountains marked with all kinds of information, which is already the highest level of map production in this era.

But the contour line, the scale bar, and the color separation map are all inadequate, and if you want to use this thing as a teaching map, the military generals may be able to understand it, and the civil officials who have no knowledge of maps will be blind.

"Not satisfied?" Cheng Yanjin stepped forward and asked dissatisfiedly, this map was already a treatment that only these generals could enjoy.

Li Tai said in disgust: "With your wisdom Duke Lu, it is difficult for the little nephew to explain it clearly to you.

Hello is really good, you can understand it, but my goal is to make everyone understand me.

Now, look at the blankness in the depths of Kong Saijiu's eyes...... I don't want to play the piano to a cow.

Take the colored ink. ”

Kong Yingda suddenly woke up with a shiver while napping, I really want to hear someone calling the old man?

……

Don't think that color painting is the patent of oil painting, although Chinese painting is common in ink painting, color painting is by no means a rare thing.

Yan Wan's second uncle Yan Li's original portraits of the emperors of the past dynasties and the portraits of the twenty-four heroes of the Lingyan Pavilion are all color paintings.

The chamberlain took various colors of ink, and Li Tai picked out green, blue, black, and white, and then repainted the mountains and rivers of Liaodong respectively.

He used his pen to draw ink separately, and continued to sketch and smear along the original simple lines of the map.

After a stick of incense, the green Changbai Mountain, the large and small Xing'an Mountains and other mountain ranges are presented like winding dragons, the blue Heilongjiang River and the Liao River shuttle between the mountains and plains, and the rest of the Tumen River, Yalu River, Songhua River, Nenjiang River and so on are distributed like blue blood vessels.

Then he painted the Songhua River, the Liaohe Plain and the Nenjiang Plain, and he added the Korean Peninsula and the Japanese archipelago in the same way.

He looked at it, frowned, and drew various mineral specialties throughout Tohoku and Japan, and carefully annotated the climate of Northeast Asia.

At this point, the emperor and his ministers were surprised to find that the map of Liaodong, which was originally composed of monotonous lines and symbols, had become a panoramic map of Northeast Asia with clear mountains and rivers.

Although there are no contour lines and no scales, it does not prevent people without common sense of maps from discovering the hidden secrets of the Great Northeast from this map.

"Hahaha, wow, King Wei, you kid is really good, the original map was only a general in the army who could see the mystery at a glance, but now even Kong Yingda, an old immortal, can see the good luck of Liaodong.

It is worthy of being the offspring of the old husband and son-in-law, Your Majesty, your Li family's seed is good, and your brain is really good.

Haha, this map will be taken home by my old Cheng Ke. Cheng Yanjin really lived up to expectations, and jumped out as a demon as soon as possible.

Li Shimin said angrily: "Cheng Zhijie!

When you see good things, you have to go home to pick them up, do you want to reward you with two baskets of toilet chips? ”

Cheng bit Jin Xi and said: "Zhong, the toilet chip given by His Majesty, Lao Cheng will dry him when he uses it, and give Kong Yingda's old immortal one piece a piece, so that they can all be touched with the royal luxury and the blessing of Lao Cheng!" ”

Everyone suddenly had a surge in their throats, and Kong Yingda trembled and said: "Old man Cheng, you deceive people too much, deceive people too much!"

Old man......

Ahem......"

Li Tao flew up and kicked Cheng Biting Jin, and then the two old goods scuffled, and Li Shimin slowly closed his eyes and entered the object and I forgot about it.

Li Tai looked at this group of Zhenguan ministers who did not go offline, and it turned out that reality is always more exciting than history.

Today's scene, the history books of later generations will truthfully record how handsome the King of Wei was, and after being surprised by the talent of the King of Wei, Lu Guogong and the British Duke had a profound discussion and friendly exchanges.

“…… mink, iron ore, ginseng, gold mines, Songliao Plain and Nenjiang Plain, large areas of black soil......

Judging from this picture, can the Mo Fei Han people in Liaodong also take root? ”

Wei Zheng is a real person, and he vaguely touched Li Tai's thoughts.

"Yes, that's the core of what Tai is trying to say today." Li Tai opened the case.

Li Daozong sighed: "From this point of view, where is Liaodong a barren land with poor mountains and bad waters, it is not an exaggeration to say that it is a cornucopia.

Qingque'er, if Uncle Wang remembers correctly, you have never left Chang'an, let alone been to Liaodong, how do you know so much about Liaodong? ”

Li Tai said with a smile: "Uncle Wang, haven't you forgotten that my nephew spent three years repairing the "Chronicles of the Kuodi", and in the past three years, I have almost walked through the Tang Dynasty on the books and maps.

During the revision of the book, I pondered how to improve the drawing of the map, and studied the topography of the mountains and rivers of the Tang Dynasty along the way. ”

Chu Suiliang praised: "King Wei is erudite, and the old man has seen it today." ”

Li Shimin said with a smile: "Dengshan is too famous, you don't know Qingque'er's temperament, the more you praise him, the more energetic he becomes." ”

Qingque'er, don't sell Guanzi, let's talk about your geoscience. ”

Li Tai said aggrievedly: "The sons are not showy, the main reason is that the foundation of ministers like Lu Guogong is too thin, and the sons and daughters don't do a good job of laying the groundwork, they can't understand." ”

When he said this, Cheng Yanjin stiffened, "bang", and his eyes suddenly received a punch from Li Tao and turned into black eyes......

"Let's get started, Fang Caitai asked you three questions:

Is Goguryeo worth fighting?

How to fight?

What will we do with it after it is defeated?

The core essence of these three issues is the formulation of Datang's national defense and foreign policy, that is, the territorial defense and the response strategies to the surrounding countries and ethnic groups, and what standards should be used to formulate and implement them. ”

Lee Tae-tae told us that it would not be a simple process to get a group of medieval elites to accept a new view of governance.

Fortunately, this is the Tang Dynasty, not the weak Song Dynasty, and he has enough confidence to convince Li Shimin and the ministers.

Kong Yingda, the prince of the country, asked Li Tai to tease him twice, this time he was more active than the generals, and he answered neatly: "Hmph, why does the King of Wei ask knowingly, as we all know, the major affairs of the country are in worship and Rong."

In other words, what is my Datang...... The formulation of national defense and foreign policy should be carried out in the general interest of defending our own name and teaching Taoism.

Let's fight Goguryeo, naturally because this group of Liaodong barbarians disobey the king's disobedience to the Heavenly Empire, and all of my Yan and Huang people will be punished! ”

Wei Zheng was even more murderous and said: "Yes, if it is not my race, its heart will be different!" ”

Li Tai's heart is surging, this is the reason why he loves Datang to death!

This is the Datang Meteorology, the principal of the Central Party School, an old man who faints from killing chickens, and can also shout and kill when facing the problem of alien races.

Wei Zheng, a civil servant, can be more evil than a general, and he will not tolerate aliens who offend the Tang Dynasty!
