Before you know it, March passed quietly.

Zhang Yunwen buried his head in the Military Academy, and almost reached the realm of 'not hearing anything outside the window'. First trained soldiers, then compiled teaching materials, until one day, when the Liu brothers appeared in front of him, he suddenly woke up. I originally said that I would accompany my two brothers to Nanyang to ask for relatives, but now I am so busy that I almost forgot about it.

"Could it be that the two brothers will be lonely for a long time? Long nights and need someone to warm up the bed? Seeing the serious looks of the two brothers, Zhang Yunwen couldn't help but laugh.

Liu Yong and Liu Wu suddenly blushed, and said with a sneer: "Third brother, it's not that your eldest brother and second brother don't know anything, and they know that you are so busy and still come to bother you!" But if you look at the eldest brother and the second brother, it's twenty-one this year. The guys in our military house, as big as my brother, have already hugged the baby! ”

When Zhang Yunwen heard this, he apologized: "What the two brothers said is true! It's the little brother who was negligent! In this way, I still have a little manuscript in hand that I have not finished, and there are still some things in my hands that have not been explained. Seven days at most, after seven days, the younger brother will accompany the two brothers to Nanyang together! ”

The Liu brothers immediately smiled: "Okay! As long as the third brother can accompany his brother, don't say seven days, even if it is ten days, you can wait! ”

"But the eldest brother and the second brother must remember, you must ask for leave in the Zhichong Mansion, don't run away like this!" Zhang Yunwen finally admonished with still unease.

"Yes, yes!"

After sending the two out of the house, Zhang Yunwen sat down again and continued to compile teaching materials. Next to him, there were already three or four book manuscripts. Among them, such as "Campaign Science" and "Military Logistics", which are the textbooks of the Frunze Military Academy, he once read them by heart, so he directly copied them in his memory. As for "History of War" and "Contract Tactics", he only remembered the headings of the chapters, so he had to write down the headings, and then slowly fill in the middle content.

As for the military academies, reconnaissance battalions, investigation institutes, and equipment institutes, they took the time to take a look, and if there was nothing wrong, they just slipped away.

Today's reconnaissance battalion is stationed in the south of Xuanwu Gate, where the former cantonment soldiers were located, and the cantonment soldiers were transferred to Chongxuanmen. As soon as I arrived at the camp of the reconnaissance camp, I felt that there was an inexplicable atmosphere inside. The atmosphere was somewhat like the tension that had filled the air before the Great War. Zhang Yunwen took a look at it and knew that these guys were conducting a live exercise under the leadership of Li Yang. Now every secret place in the camp has more or less hidden soldiers. After looking at it twice, he felt that Li Yang led the troops well, and he could almost completely hand over the reconnaissance battalion to him. So he slowly exited the camp.

Then there is the Institute of Inquiry. Today's investigation institute is no longer on Lin Ran's Zuiyun Tower, but has moved to the palace in the south of the imperial city. I work outside of a large courtyard. The Intelligence Bureau and the Statistics Bureau, which were separated from the Investigation Yuan, were respectively located in the Ministry of Military Affairs and the Ministry of Household Affairs.

When he arrived at the investigation institute, as soon as Chen Quankang saw him, he said anxiously: "My lord, I'm looking for you!" ”

Seeing Chen Quankang's appearance, Zhang Yunwen suddenly said, "Did something happen?" ”

Chen Quankang handed over the translated note in his hand, Zhang Yunwen took it and looked at it, only to see that it read: "Tuli was assassinated three times during the year!" Three 10,000 tribes under the tent took refuge in Jieli! The Xi, Khitan, Fuyu and other departments under its jurisdiction all have antipathy! ”

As soon as Zhang Yunwen looked at this note, he knew that it was Zhao Yi who had sent it from the Turks. At the beginning, the five of them were ordered to stay by Tuli's side, just to prevent accidents, to monitor and protect Tuli on the other. In Zhang Yunwen's memory, Tuli would raise a clan to surrender to the Tang Dynasty. It was after he had a rift with Jieli that he took refuge in Datang when he was desperate. And what Zhang Yunwen wants to do is to try to strengthen his power before Tuli takes refuge. This can not only enhance the strength of the Tang Dynasty, but also weaken the power of Jieli, so that there can be less pressure when conquering the Turks.

"Give Zhao Yi and the others an order, let them protect Tuli well, and at the same time expand his power as much as possible! In addition, try to provoke the contradictions between those tribes and Tuli, and let those tribes take refuge in my Datang! Zhang Yunwen pondered for a moment and said to Chen Quankang.

Chen Quankang suddenly bowed down and said, "Wow! ”

Zhang Yunwen came out of the investigation institute and felt that it was necessary to report this matter to Li Shimin, and immediately came to the side hall of Linde Hall to see Li Shimin.

After telling Li Shimin about the whole thing, Li Shimin groaned: "Yunwen did a good job!" My Tang Dynasty is bordered by the Turks in the north, and I have been deeply disturbed by the Turks all year round. If you can split the Turks and make the Turks surrender, then when you conquer in the future, you can attack from both sides, and you will destroy Jieli in one fell swoop! As for those Xi, Khitan and other tribes, they came to surrender to my Datang, which not only increased the strength of my Datang, but also separated the relationship between Jieli and Tuli. If those tribes come to surrender, then Jieli will definitely ask Tuli for doing things unfavorably, and the two will definitely fall out, Yunwen, it's really good! ”

When Zhang Yunwen saw Li Shimin say this, he breathed a sigh of relief at the moment, and said to Li Shimin: "It's good if Your Majesty says this!" Yunwen still thinks that he has crossed the limit! ”

Li Shimin suddenly deliberately lowered his face and said, "Yunwen, what are you talking about!" You are the head of the Investigation Agency, so it is only natural for you to deal with these matters. Only when you encounter something indecided, can you repay me! ”

"Whoa!" Zhang Yunwen bowed secretly with joy in his heart.

"By the way, Your Majesty, Weichen wants to take a month off!" Zhang Yunwen saw that after finishing his business, he talked about his private affairs.

"Huh?" Li Shimin asked with some curiosity, "I don't know why Yunwen asked for leave?" And what about the agencies under your jurisdiction? ”

Zhang Yunwen said: "Wechen's two elder brothers are going to Nanyang to say goodbye, and Wechen wants to accompany them!" As for those departments, Wechen will definitely arrange everything before leaving! ”

"Oh!" Li Shimin nodded suddenly, "I see!" Then Yunwen will go by himself! Hehe, your two brothers will become a family as soon as possible, Yunwen, you should marry Runan as soon as possible! ”

Zhang Yunwen's face suddenly turned red: "This ...... Well, let's talk about it later! ”

Out of the Lin De Palace, Zhang Yunwen walked to the palace in the south of the imperial city.

In the large courtyard that used to be used as a prison, the current equipment yard is located here.

Zhang Yunwen approached the equipment institute and wanted to arrange future work.

Knowing that Zhang Yunwen was coming, Master Lu and a middle-aged man greeted him together: "I've seen Master Zhang!" ”

Zhang Yunwen looked at the middle-aged man, and the master Lu next to him hurriedly introduced: "This is Yan Lide, Yan Yuanwai, and Wailang of the Ministry of Engineering!" His Highness's new head of the Equipment Academy! ”

Zhang Yunwen suddenly said secretly, another historical celebrity. This Yan Lide was the brother of the Tang Dynasty painter Yan Liben, and later became the secretary of the Ministry of Industry. After his death, Yan Liben succeeded him as the secretary of the Ministry of Industry. The two brothers successively served as the secretary of the Ministry of Industry, and for a time they were listed as beautiful talks.

After greeting Yan Lide for a while, he said, "Director Yan, this official is going to leave Chang'an for a while, now come and arrange things!" ”

Yan Lide said: "I don't know what arrangements the adults have? ”

Zhang Yunwen was silent for a moment and said: "In addition to manufacturing grenades, steel crossbows and other weapons during this time, you have to spare people to do one thing!" ”

"What's the matter?"

"Make a batch of iron cylinders!" In fact, what Zhang Yunwen wanted to make was a cannon barrel. However, the gun barrel has extremely high requirements for material and accuracy, so Zhang Yunwen said that the iron barrel is made.

"What's so hard about this!" When Master Lu heard this request, he immediately smiled and said, "No matter what kind of iron cylinder the adults want to make, I will make it in the future!" ”

Zhang Yunwen smiled "hehe": "You really did it?" After saying that, he asked for the barrel one by one. After listening to these requests, Master Lu couldn't help but be dumbfounded.

"My lord, isn't it just to make an iron cylinder, there are so many requirements!"

"Can't do it?" Zhang Yunwen asked with a smile.

Master Lu's face suddenly turned red, and then he said loudly: "Isn't it just an iron cylinder!" Wait, sir, when you come back, I'll show it to you! ”

Zhang Yunwen patted Master Lu on the shoulder: "Okay, that official is waiting!" ”

After arranging the affairs of various institutions, Zhang Yunwen was ready to go to Nanyang.
