Many people know the government military system, but few people know that in fact, the 'government' in the government military system is divided into three types.

One of them, the house, the ordinary folding house. Second, the Governor's Office, also known as the Governor's Office. At the beginning of the Tang Dynasty, the Sui system was inherited, and its leader was the marching chief or the grand commander. Set up the Governor's Mansion in important places and control the nearby Ojichong Prefecture. After Li Shimin ascended the throne, in order to reduce the authority of the generals, most of the governors in the Central Plains were abolished, and only places similar to Bingzhou, Jizhou and other places remained, and the governors near the border still existed. For example, Li Ji was appointed as the governor of the annexed state, which was to let him lead the military of the annexed state, guard against Xue Yantuo in the north, and supervise the Eastern Turkic tribes at the same time.

And the third is the capital protectorate. The duty of the Metropolitan Protector is to "control the Zhufan, comfort the conquest, and punish the merits", compared with the Metropolitan Governor's Office, the general difference is that the Metropolitan Governor is internal, and the Metropolitan Protector is external, involving foreign affairs.

The level of the protector and the governor are all the 'feudal officials' of the Eight Classics, and according to the official system, they must be at least the third grade. Li Mu's level is barely enough, while Li Siwen is far behind. Li Mu wanted to promote his brother, but there was no such promotion, and Li Siwen really did not have the ability to serve as the protector, so Li Mu did not force it, he received the protector himself, and let Li Siwen receive the title of Changshi. Even if it is a long history, Li Siwen is not at a high level, but Li Mu can't find someone to serve casually, so although the level is not enough, he is also 'extra promoted and appointed'.

Li Mu taught Li Siwen how to plant the potatoes he brought, asked Li Siwen to set up a farm, hired homeless people to plant potatoes, and ordered Bai Gensheng to be in charge of the farm, lest he get wild and run around as he gets older.

At the same time, he received envoys from the countries of the Western Regions. These envoys seemed to have discussed and wanted to follow Li Mu to Chang'an to meet Li Shimin.

This is not surprising, previously due to the relationship between the Western Turks, the countries of the Western Regions faced warbands. Many countries dare not communicate with Datang, and even if they do, they are secret, and now that the Western Turks and Datang have become brother countries, there is naturally no such mustard, and friendship with Datang is also the proper meaning of the topic.

Li Shimin's favorite is this kind of pomp, Li Mu will naturally do this favor, let Li Siwen gather all these envoys in one place, and bring them all with him when he goes back. Ni Yu also sent a messenger to go back with Li Mu, and while testifying for him, he also had to hand over the credentials.

There is no banquet in the world, and after Li Mu left Chang'an for four months, he finally set off to return to Chang'an. Before leaving, Li Mu left a road marker stone so that it would be convenient for the flying pigeon to pass on the news in the future.

Li Siwen sent Li Mu to Mayi, and wanted to follow, but was rejected by Li Mu. Li Siwen couldn't stop crying, he was just a little cowardly, but he wasn't stupid at all, he knew what kind of desperate situation Li Mu would face after returning to Chang'an. Even this separation, it is unknown whether there will be a chance to meet. Therefore, he was extremely reluctant to hug Li Mu and was unwilling to let go.

Li Mu patted him lightly on the back and said, "Siwen, don't cry. Remember the words of the eldest brother, a man lives in the world, he must dare to face it, crying will not solve any problems. Faced with it, even if it doesn't work, he is still a man with a handle! ”

"Big brother, I-"

"Remember what I said to you, do what you have to do, big brother is gone!"

After reading the words on the note, Li Shimin threw it into the brazier and burned it. Father-in-law Gao came in from outside and said, "Your Majesty, the king of Hejian County has arrived." ”

"Cousin, please come in."

Li Xiaogong entered the Taiji Hall and wanted to salute. Li Shimin helped him up and said, "Cousin, I don't go around the corner, this time I came to my cousin because I wanted my cousin to bother." ”

Li Xiaogong was stunned for a moment, and wanted to refuse politely. He didn't know whether Li Shimin was sincere or false, in case it was a temptation, he agreed again, but the big thing was not good.

"Don't worry about it, cousin." Li Shimin saw what Li Xiaogong was thinking, and took the first step and said: "Li Mu boy went to the Western Regions this time to solve a confidant problem for me. At that moment, he roughly told Li Xiaogong about the situation in the Western Regions. These news, now in the court, are still blocked. Only a few people such as the eldest grandson Wuji and Fang Xuanling know about it, and Li Xiaogong usually doesn't go to court, so he naturally doesn't know.

After listening to Li Shimin's words, Li Xiaogong was completely stunned. He looked at Li Shimin in a daze and said, "Your Majesty is not joking, right?" ”

"I didn't speak clearly enough?"

"No, no, no," Li Xiaogong hurriedly waved his hand and said, "Chen just can't believe it - this is too bizarre, how did Li Mu do it?" The Western Turks are in civil strife, and they are facing the mud, which can still be believed in one or two. But how could he persuade the Western Turks to make an alliance with the Tang Dynasty, and how did he even make his father-in-law the king of Gaochang? How? ”

"I don't know." Li Shimin smiled bitterly: "But Li Mu, this kid, can always be surprised, and he has never hidden it from me in major matters, and I still believe in him." I have already sent a message to Li Ji and Hou Junji, asking them to obey Li Mu's dispatch and let him decide everything. ”

"I still can't believe it—"

"Don't talk about that." Li Shimin said with a straight face: "I believe in Li Mu, so I have to make some preparations. If it is really as Li Mu said, the Western Regions have been decided, and I plan to set up a capital protectorate in Dingxiang to oversee the affairs of the Western Regions. Dingxiang Protectorate is the first Protectorate of the Tang Dynasty. And the affairs of the Western Regions are as heavy as a thousand pounds. I think about it, this is the duty of most of the protectors, I have to be cousins, and others can't believe it. ”

Li Xiaogong said in his heart, who can believe this? The person you don't trust the most seems to be me, right? The thought turned in his heart, and Li Xiaogong still said: "Your Majesty, the minister has not led troops for many years, and the matter of armament is wasted. Besides, Chongyi, this kid, ran to Zhenla without permission and almost died outside, and the ministers have been educating him in recent days, and they have no thoughts, for fear of delaying His Majesty's major affairs. Your Majesty is better to choose someone else, like Qin Qiong, Wei Chigong, it's really okay to bite the gold, aren't they all idle? ”

"General Wei Chi is old, and Dingxiang is more than 6,000 miles away, and I really can't bear to let him run around tirelessly. Qin Qiong is injured, and the climate in the Western Regions is uncertain, so it is not suitable to recuperate, nor can it. As for Cheng Biting Jin's rammer-" Li Shimin smiled and said, "I can't believe him, cousin don't have to resign." I asked my cousin to return to Chang'an before, and I admit that I was worried. But that's all in the past, and my cousin is my cousin after all. What can be counted on in major matters has to be one's own relatives. With my cousin sitting calm, I can sit back and relax. ”

"This ......"

Li Xiaogong was in the prime of life, how could he be willing to be an idle prince, but when he was leading the troops, he was really worried that Li Shimin would be jealous, and it was difficult to make a decision for a while, so he said: "Your Majesty, can you let me think about it for two days?" ”

"Okay, then give me an answer in three days."
