Li Shimin was furious in the Taiji Palace, and the courtiers did not look good when they heard the news.

Because Tuyuhun is pinching Datang to death. From the locust plague in the fourth year of Zhenguan to the present, Guanzhong has been in a state of food shortage and has not recovered.

In addition, in the fifth year of Zhenguan, there was a lot of wolf smoke in the north, and Li Shimin put down rebellion everywhere. There are also six years of Zhenguan, seven years of rebellion, and so on.

Anyway, in the past few years, Datang has not had a few days of peaceful life. Li Shimin hated it, so angry that he pointed in the direction of the sandbar and scolded Fu Yun for being a capricious villain.

Why is Fu Yun a villain, because Fu Yun once sent troops to invade Minzhou, Suzhou, Lanzhou, and Kuozhou in the Tang Dynasty when he was in the fifth year of Wude.

But he was defeated by Li Changqing, who was left behind in Minzhou at the time, so Tuyuhun was honest for a few years. After Li Er ascended the throne, he sent troops at the end of the third year of Zhenguan, and at the beginning of the fourth year of Zhenguan, the Eastern Turks were destroyed.

This can scare the surrounding countries. You must know that the Turks have been entrenched in the steppe for hundreds of years, and it has always been a nightmare for all countries.

In the face of the Turks, except for the Central Plains Dynasty, which occasionally resisted, other countries have always been the horse grazing land of the Turks.

The dark clouds that had been entrenched over everyone's heads for hundreds of years were dispelled by the Tang Dynasty. frightened, the surrounding small countries hurriedly ran to Chang'an to show their loyalty to Li Shimin, including Tuyuhun's envoy.

At that time, the envoys of these countries could be said to be more fleshy and more fleshy, and they were to give Li Er the honorific title of Heavenly Khan, and to ask for the construction of a towering Khan Road.

It's only been a few years, and Tuyuhun has started to do things again, how can Li Shimin not be angry. Contrary to Li Shimin's thunderous state, the old generals were excited.

There is a war to be fought, there is a war to be fought means that there is military merit to be taken, and there is a war to be fought means glory and wealth.

So they all geared up, waiting for His Majesty's order, and then began to fight for the position of commander of the three armed forces with their fists.

It's just that although Li Shimin was furious, he was not carried away by anger. A war must be fought, but how to fight it depends on a way and a method.

Datang has been tossed in the past few years, and it is simply unable to support a large-scale war, especially a national war.

The war is about logistics, grain and grass, and economy. As soon as the army was drawn out, the money had to flow out like flowing water.

And now, Datang's treasury is empty enough to run mice. So Li Shimin spread his hands and threw this matter to the two prime ministers of the political hall.

As soon as the two prime ministers are combined, let's fight. It's just that we have to find a way to solve the problem of grain and grass logistics before fighting.

There is no food and grass in the north, so you can only find a way from the south. Last year, Feng Ang had great success in planting three crops of rice in Lingnan, and this year Tuyuhun launched an attack on Datang.

A holy decree went south as fast as possible, and the sailors entrenched on the river became a ready-made fleet of grain carriers.

At the same time, the envoys sent by the Tang Dynasty to Tuyuhun to delay time also set off from Chang'an, and the main envoy was named Zhao Dekai, whose task was to find a way to drag down Fuyun Khan and make him not attack so early.

As for the means of delay, it is nothing more than coercion and inducement, anyway, no matter what means Zhao Dekai uses, as long as he can delay Fu Yun for more than three months, it will be considered a great achievement.

…… The time came to the second day of February, the day when the dragon raised its head. Zhao Dekai, who was holding the envoy flag, came to Fu Yun's Chinese army camp and faced the old Fu Yun Khan.

Even though it is already February, the Central Plains is already the season for the grass to grow and warblers fly, and the snow on the grassland is still not knee-high.

Zhao Dekai is no stranger to such a scene, when Tang Jian was an envoy to the Turks, he was the second deputy.

Zhao Dekai ignored the coercion of Tuyuhun's tens of thousands of troops, with a calm and indifferent smile on his face.

It was followed by a long convoy of hundreds of wagons. These are all gold, silver, cloth, silk and silk things that His Majesty Li Er gave to Fu Yun Khan.

In the fourth year of Zhenguan, Tuyuhun sent envoys to Chang'an to pay tribute, and was named the king of Xiping County by His Majesty Li Er. Coming to the door of the commander of the three armies, Zhao Dekai dusted off the non-existent dust on his shoulder, and his whole temperament changed, like a long sword out of the sheath.

Then, under the leadership of Fu Yun's personal soldiers who received him, he stepped into the Chinese army tent where Fu Yun lived. It's just that as soon as he entered the big tent, Zhao Dekai's brows wrinkled imperceptibly, and then returned to normal.

Even in winter, the smell in the big tent where Fu Yun lived still made Zhao Dekai feel a little uncomfortable.

The smell of all kinds of cow dung, sheep dung, and horse dung almost suffocated Zhao Dekai. The only use of this manure in the Great Tent is as fuel.

There were not many people in the tent, only an old man in a thick fur coat, and two men who were still shirtless in the winter, standing guard on either side of the empty throne.

The fur on the old man's body seemed to have not been washed for a long time, and the oil on it had congealed into lumps.

He was roasting a skinned lamb by himself beside a fire made from cow dung. Zhao Dekai recognized at a glance that the old man who was roasting the lamb was the initiator of the dispute between the two countries, Fuyun Khan Murong Yun.

Fuyun Khan reverted to the surname Murong, and the surname Murong was once as famous as Tuoba in history, and it was the royal orthodoxy of the Xianbei branch.

Zhao Dekai came to the old man's side, and bowed his hand to the old man without humility or arrogance: "This official Zhao Dekai, meet His Royal Highness the King of Xiping County, Your Highness, Your Majesty has a will for you." Hearing Zhao Dekai's voice, the old man did not turn his head, as if the lamb in front of him was more important than anything else.

After the old man applied a layer of spices to the skin of the lamb, he replied lightly: "This roasted lamb must be mastered well, if the fire is too big, this tender lamb will be easy to burn, unable to lock the juice, and the lamb will lose its own fat taste." If the fire is low, the meat of the lamb will become very woody, and it will become indistinguishable from ordinary mutton. His Majesty's envoy to the Heavenly Khan is here, but the king is too busy to pay the full salute, so please wait for the envoy, if the envoy is impatient, now it is necessary to think of His Majesty's will of the Heavenly Khan. Fu Yun's voice was dry and hoarse, with a hint of coercion, obviously he wanted to give Zhao Dekai a dismissal, but his tone was still calm.

When Zhao Dekai heard this, a trace of displeasure flashed in his eyes. But when I thought of the task of this time, which was to delay enough time for the country to raise logistics food and grass, I had to force down the slightest displeasure in my heart.

Then he took out a copy of the decree from his bosom and read it. The format of the holy decree is very formal, and pressing the four and six is just a basic operation, and Fu Yun must not understand it.

The content of the decree was first that Li Shimin reprimanded Fu Yun in a stern tone for provoking the dispute between the two countries without authorization, destroying the diplomatic relations between the two countries, and causing the people of the two countries to fall into dire straits.
