"Are you sure?" Huo Gang looked at Li Chengqian a little strangely and asked.

"Don't dare to deceive the teacher." Li Chengqian said in a serious tone.

"Very well, you will be half a year in two months, and in two months, I will have someone prepare the relevant accommodation for you, and you can come to me and start your classes." Huo Gang said very simply.

"Yes! Thank you, teacher. Li Chengqian saluted directly in a happy tone.

"You're welcome, after you go back, you mainly think about a few questions, you have to think about it, why the hundred schools of thought in Datang can't be realized now, why can things that can be easily executed in Dahan can't be executed in Datang? Once you've figured out these questions, there's a lot you can see. Well, you take the book back. Huo Gang thought for a moment, stood up, and then took out a book from the bookshelf behind him.

handed the book to Li Chengqian, who respectfully took the book.

"Okay, you can go back and remember to complete the task I told you." Huo Gang said with a smile.

"Yes." Li Chengqian agreed, and then bowed again and withdrew directly.

After leaving from Huo Gang's leader's mansion, Li Chengqian looked down and saw the book in his hand, the title of which made Li Chengqian a little stunned, because there were only a few words on it: Huo Gang's Selected Works.

cough, if there is another person from the next generation, he should know where the content in it comes from, but the original name cannot be used here, so Huo Gang simply thickened his skin.

Of course, this book has also been re-edited, and some of the content in it has also been improved by Huo Gang, and it is impossible to take it out completely, isn't that your own life? So it is certainly impossible to follow the original tone, but even if it is not according to the original content, there are still too many theories that are ahead of the world.

For example, when it comes to class analysis, there is a lot of content in this that allows you to figure out which classes are standing and where, depending on your position in the royal family and so on.

Anyway, it is impossible for Huo Gang to completely copy the future generations, and it is impossible to position himself according to the current emperor.

As for how much Li Chengqian can understand after reading it, it depends on Li Chengqian's own.

After returning to his place of residence, Li Chengqian did not read the book for the first time, but began to write what he had sorted out again.

In the evening, Li Chengqian finally finished writing this family letter, and after writing it, Li Chengqian thought about it, and did not choose to hand it over to the people who followed him, but went directly to Zhao Er.

Ask Zhao Er to help me tell the letter and send it to the Jiayuguan side, and then the people from Jiayuguan will hand it over to the general in charge of the Jiuquan side.

Li Chengqian forwarded a total of two letters, one of the two letters was handed over to Chai Zhewei, who is currently the general of Jiuquan, and the other letter was naturally directly addressed to Li Shimin.

Zhao Er naturally did not hesitate about this, he knew that this letter was very important, so he arranged for the golden eagle to send them to Jiayuguan as soon as possible, and then the people from Jiayuguan also sent them directly to Chai Zhewei's hands.

After receiving these two letters, Chai Zhewei directly opened the letter to him, and after reading the contents, Chai Zhewei immediately arranged for someone to send this special letter directly to Chang'an in an expedited manner of 800 miles.

Two days later, Li Shimin, who received the letter, was a little stunned, because he didn't need to look inside, just by looking at the contents on the envelope, Li Shimin knew that it was written back by Li Chengqian, but it was sent back with an expedited of 800 miles, and Li Shimin still opened it as soon as possible, although he didn't know what kind of content it was.

The thick letter paper made Li Shimin look very carefully, but when he saw part of the content, Li Shimin still couldn't help but stand up directly from his position, his face was full of shock, and he couldn't help but read this paragraph again.

After reading this paragraph, Li Shimin still looked incredulous, if it wasn't for Li Chengqian's writing, and told him that after he personally got on the train and experienced it, Li Shimin couldn't believe it anyway.

But now, no matter how he can't imagine it, Li Shimin can only believe it.

Similarly, just like Li Chengqian said, Datang must have this thing. In this letter, Li Chengqian also told some of Huo Gang's thoughts, especially the problem of the worker, Li Shimin considered these problems, but these are not important, because all the technology is in the hands of the Han, no matter what the other party's conditions, they Datang want to have a train, this is the only way.

Therefore, after Li Shimin read the entire letter, he immediately called Chang Lin and asked him to call all those important ministers, including Wei Zheng, who had not been back to Chang'an for a long time, also called him directly.

If this matter wants to be done, it must be negotiated, but how to negotiate, whether to let Wei Zheng and several other ministers go to Jiuquan, or something else, Li Shimin has no other ideas at present, but this train must have.

The ministers who should have arrived soon, Li Shimin did not hide it, and directly handed them the envelope in his hand, all the ministers immediately looked down, and when they finished reading, all the ministers almost all had the same expression, and they all subconsciously raised their heads to look at Li Shimin and asked: "Your Majesty, is this serious?" ”

"Seriously, this kind of thing can't be faked, not to mention that this is sent back by the prince himself." Li Shimin said in a serious tone.

All the ministers have some numb claws now, this thing ...... has far exceeded their imagination, or rather, has far exceeded the point of a national strategic point, there is no doubt about what such a thing means to Dahan, so what about Datang?

Datang needs it more than Dahan, not to mention anything else, just Datang's next northern expedition and southern expedition need these things.

The reason is very simple, when Huo Gang agreed to sell grain to Datang, and sold grain at a very low price, without limiting the quantity, Li Shimin probably knew Huo Gang's thoughts, although he didn't understand the food security of a country, mainly because people in this era did not have this awareness.

The reason why there is no such awareness is because everyone in this era does not have enough food to eat, and someone sells you so much, why don't you hurry up and buy it? Where would you think about the fact that food is subject to people's control, you won't think about it at all, because when there is a catastrophe year, there is still no food to eat? The rulers have long been accustomed to it, so they do not have this awareness.

At least when they don't see the consequences for now, they won't think of it, and when they realize it, it must be when a large amount of land in Datang has been cultivated with cash crops, and at that time, it is not possible to complete it in a year and a half if they want to turn back.

Therefore, Li Shimin knows very well that if this train route is completed, wouldn't it mean that Dahan's grain can be transported to Datang at a very fast speed or even a very low price? Although he knew that the shipping cost could not be cheap, considering the number of shipments it had in one go, it would certainly be more cost-effective than transporting it by horse-drawn carriage.

Not only that, but the Datang economy along the Hexi Corridor that this railway can drive is not only closely connected with Dahan, Chang'an and Wuwei. The economy along the way will naturally develop rapidly, and commerce will also develop rapidly, and in just half a year, Li Shimin has already enjoyed the benefits of business, so he no longer looks down on that little agricultural tax.

Li Shimin has already thought that if this railway is built to the south of the Yangtze River, and then from Chang'an to Guyouzhou, that is, the place where the 40,000 acres of black soil are located, the nomads in the north? Li Shimin can say that since his Tang Dynasty, all nomadic threats have not existed!

The ministers soon began to discuss it as well, but their discussion ...... In fact, there is no discussion, because this thing, Datang must have, it is nothing more than a question of what to pay.

"Your Majesty, the minister is willing to go to Jiuquan in person to negotiate with Dahan on this railway." Du Ruhui saluted very simply.

"The minister is willing to go with Du Gong." The eldest grandson Wuji next to him said directly without hesitation, he can not care about those things in the past, but this matter is not good, the eldest grandson Wuji must be involved.

"The minister is also willing to go." Fang Xuanling and Wei Zheng almost saluted at the same time.

Looking at their actions, Li Shimin actually wanted to say that I still want to go in person, this time the matter is too important, so Li Shimin feels that it seems better for him to talk to Huo Gang in person.

"Pharmacist." This time, not only these civil ministers, but even the military minister Li Shimin called over, Li Jing and they were all there, so Li Shimin simply called Li Jing.

"The minister is here."

"If the Han relies on this railway to raid my Datang interior, do you have a preventive strategy?" Li Shimin asked directly, although it is impossible for the relationship between Datang and Dahan to have this situation, because if you really want to do that, it is okay not to save Li Shimin at that time, but no matter how good the relationship between the two countries is, there should still be precautions.

"This railway is recorded in the letter of His Royal Highness, it is based on the railroad tracks to travel, if the railroad tracks are destroyed, I think this thing can be stopped, but if you simply consider the Han attack on the Tang Dynasty, I don't think this railway is important, with the advantage of the opponent's cavalry, you can directly bypass Jiuquan, Wuwei and other places directly into Jincheng (now Lanzhou), after the other party controls the vicinity of Lanzhou, it is almost impossible for us to counterattack."

"After controlling Jincheng, the entire Hexi Corridor is like a turtle in an urn, it is only a matter of minutes to take it, in this case, with the ability of the other party, the Hexi Corridor can be digested in a very short time, and when the time comes, they can cross the Yellow River and directly attack the hinterland of my country, and if they retreat, they can also defend the gateway of the Hexi Corridor, and our side has almost no room for resistance." Li Jing shook his head slightly and said.
