Xizhou is a small city bordering Gaochang and Datang, and it is also the first transit station and supply city after the Silk Road left Datang.

It is less than 800 miles away from Gaochang Country and less than 1,000 miles away from the sandbank. After thinking back and forth, Zhang Zheng suddenly understood what his father meant.

The geographical location of Xizhou, I can't see anything now. But if Datang wants to get involved in the Western Regions, then the city of Xizhou must be firmly held in his hands.

The distance between Shazhou and the Western Regions was too far to take on the heavy task of garrisoning troops and food as a logistics supply depot for the army.

Xizhou is like the arrow of the arrow of the Tang Dynasty's Hexi that shoots at the Western Regions, if it succeeds in taking Xizhou, the Tang Dynasty will have a base for plotting the Western Regions.

Garrison troops, garrison grain, tuntian, as a bridgehead for attacking the Western Regions, this is the role of Xizhou. This is the role of Xizhou for the Tang Dynasty, and for the countries of the Western Regions, the geographical location of Xizhou is equally important.

As the first line of defense in the Western Regions, if the city of Xizhou is broken, it will basically announce the end of Gaochang.

Because from Xizhou to Jiaohe can be described as a flat river, the entire Western Regions will be at the mercy of the Tang army's iron cavalry.

If the countries of the Western Regions want to launch a counterattack against the Tang Dynasty, Gaochang is also a nail embedded in the heart of the western part of the Tang River.

Now Li Shimin wants to take Xizhou, and it will not cause a backlash from the countries of the Western Regions in a short time, so he can only use high-pressure strategies.

It is to send a large army to scare you, and if you dare to make a move, my army will directly drive over and crush you. Destroy the country, offer Xizhou, and choose one of yourselves.

"What's the use of the child going to Xizhou, the child doesn't have the experience of being in charge of the party." Zhang Zheng spread his hands and asked his father who was standing with his hands in his hands.

"The ruling party?" Zhang Gongjin turned around and looked at Zhang Zheng with extremely disgusted eyes.

"Who said that Your Majesty wants you to be in charge of one side, at most it is for you to go to Xizhou to open up the situation, how can you let you be in charge of one side. No matter how remote Xizhou is, it is also a state, and its chief official is also a feudal official, how old are you, and you still want to be in charge of the party? ”

"Uh......" The corners of Zhang Zheng's mouth twitched, thinking that Li Shimin had finally found out his conscience, but he just wanted to be a pioneer?

"Well, the boy knows." Zhang Zheng nodded to his father, and the father and son stood on the edge of the Wei River and enjoyed the scenery on the riverbank without saying a word.

Now all this is still Zhang Gongjin's speculation, and how it will be arranged depends on Li Shimin's decision.

When Zhang Zheng and his father returned to the county uncle's mansion, the county uncle's mansion had been cleaned up and cleaned, and it had returned to its former tranquility.

Zhang Zheng and Qinghe became officially husband and wife, and they had to return to the door three days later, that is, to go to the palace. But these are all small things, and the most important thing for Zhang Zheng now is to think about how to open up the situation after going to Xizhou.

After all, Xizhou is still a city under the rule of Gao Chang. …… It was the beginning of the second half of the semester of the academy, and Zhang Zheng returned to the academy again with a large bag of things.

The days passed without any waves, and everything seemed to be peaceful. The only difference is that Qinghe and Xiao Lushang also followed Zhang Zheng to live in the villa of the academy.

It is said that he takes care of his diet and daily life. This made Zhang Zheng very distressed, because he had a lot fewer opportunities to climb over Cui Shu's courtyard wall.

The next day, Zhang Zheng called Li Tai to his villa. The master and apprentice sat opposite each other and had been discussing for most of the hour.

Zhang Zheng called Li Tai over mainly to order two things. One is the gunpowder thing, since Li Tai has already got the fireworks out.

It's not too much for him to study the artillery, the principle is pretty much the same anyway. So Zhang Zheng directly handed over this important task to Li Tai.

It is really a heavy responsibility, and Zhang Zheng definitely has no intention of announcing personal vendettas. And the second thing is the revision of the academy's textbooks.

Now that Li Tai has basically thoroughly understood the knowledge imparted to him by Zhang Zheng, the revision of the textbook has been put on the agenda.

The first batch of students of the college have undergone a year of professional education and will start internships in various departments in the second half of next year.

For new students, the educational model of the college must also change. Zhang Zheng's original intention in founding the academy was to teach the new kind of knowledge he had brought from later generations, which was not as nondescript as it is now.

So this important task, Zhang Zheng also handed over to Li Tai. Zhang Zheng's goal is to ensure that the newly enrolled students will be able to reach at least the sixth grade of primary school after passing three years of basic education.

After graduating from two years of professional education, they should at least be able to reach the level of junior high school in the future. The current conditions can only be until junior high school, and no matter how in-depth education is, it will need to be accumulated from generation to generation.

Now that he is going to Xizhou, Zhang Zheng plans to explain these two things to Li Tai in advance. Li Tai bit a peach with a bitter face and splashed juice, and responded: "Do you want me to do all these things alone?" Zhang Zheng nodded heavily and said: "I also want to help you get it together, but there are more important things for the teacher, and I really have no heart, you can, come on." ”

"Oh~" Li Tai dragged a long tail note, his mind was running at high speed, considering the difficulty of these two things.

There is nothing to say about artillery, even if Zhang Zheng doesn't say it, Li Tai plans to study it in this direction. But the adaptation of textbooks is equivalent to asking him to spread the knowledge taught by Zhang Zheng to the world.

Revitalize the division, it sounds like a good look. So Li Tai thought about it for a while, and then he responded to these two things.

"I have already explained to King Bin, if you need the cooperation of Mr. Academy, you can mobilize the power of the Academy." When it was over, Zhang Zheng gave Li Tai a reassuring pill.

Li Tai was also relieved, thinking that he would finally gather the strength of the entire academy to complete this matter, instead of catching the blind alone.

"Okay, teacher, don't worry, there are disciples in the academy." After listening to Zhang Zheng's words, Li Tai replied with a treacherous smile on his fat face.

"It's okay, you can get out." After explaining the two things, Zhang Zheng pointed to the gate of the other courtyard and signaled that Li Tai could take care of himself.

Li Tai is also not brainy, he is already very clear about this gentleman's temperament, and he stood up and walked away without saluting Zhang Zheng.

And Zhang Zheng suddenly drove Li Tai away, naturally because it was time for dinner. Zhang Zhengcai was too lazy to leave Li Tai to eat at home with such a big fat man, the amount of food was ridiculously large, what should I do if I ate the family poor?

The picture turned to Li Tai's side, and since Zhang Zheng's villa came out, Li Tai couldn't stop laughing.

Don't look at Zhang Zheng as if he was looking for something to do for him, only Li Tai himself knew that the teacher had left the name of eternity to himself.

If he can carry forward the new style of learning with the academy, the name of a generation of scholars will inevitably be indispensable in the history books of future generations.
