"Your Majesty, those weapons made of 100 steels are now backward, far less good than the weapons we are newly equipped with. Weichen has calculated an account, those replaced weapons, let's collect it and re-furnace it, and if we re-make it, the price is not low. On the other hand, other surrounding countries, such as Xue Yantuo, Turkic, Tubo and other countries, are in urgent need of weapons made of steel. In the past, Datang did not sell weapons to them because it wanted to maintain its superiority in weapons and accumulate advantageous conditions for victory in the war. But now, the weapons made of 100 steels are no longer a threat to our Datang soldiers. What if all of them were replaced with weapons made of 100 steels? Our Datang's steel-smelting technology is much higher than that of 100 steel-making, and our Datang is still constantly refining and developing newer and more advanced weapons. The advantages are still there and are constantly expanding. And the eliminated things, can it threaten Datang, so why don't we give full play to its maximum value and exchange for the money and resources needed for Datang? Xia Hongsheng stood under Li Shimin and said to Li Shimin behind the desk.

"Although it traded with the Turks and other markets before, weapons and military supplies were not included in this list. Isn't it even worse if the Turkic barbarians, who do not understand kindness, and who disturb China from time to time, if they have the advantage of the front of the army? Li Shimin said: "Therefore, all dynasties and generations have not sold weapons to them. ”

"But things are different now, Your Majesty." Xia Hongsheng continued to persuade: "Nowadays, all kinds of technologies of our Datang are emerging in an endless stream, either improving on the basis of the previous ones, or creating new things out of nothing, and these applications can be more advanced than the surrounding countries." Take the steel-smelting technique that we have improved in the military machine workshop now, the same two knives, the knives that are now equipped in the Tang Army are together with the hundreds of steel-making knives. It must be a hundred steel knives that are broken, and the new knives will not even break open. It's a lot better than the Damascus steel, well, the Uzi steel. Moreover, it will take at least half a year for Uzi Steel to make a knife, but the output of the assembly line of our military aircraft workshop will soon be able to equip a military force with a month of overtime. That's a big advantage! Therefore, His Majesty does not need to worry about selling weapons made of 100 steels to other countries. It will pose a threat to Datang. On the contrary, this move can also make their weapons never compare to Datang. ”

"Oh? How can a method that can never be compared to Datang? Li Shimin's eyes lit up and asked.

"Your Majesty, our Datang technology is advanced, and it is still improving, and it will be even more advanced in the future." Xia Hongsheng explained to Li Shimin: "Other countries are different, for them, Uzi steel is already an artifact, and Bailian steel is already the best military weapon." They don't know that there is a better and more advanced one! Therefore, if they can easily buy weapons made of hundreds of steels. So imagine which of them is willing to put in the effort and energy to research better weapon materials? They will hoard a large number of weapons made of steel, from now on, their weapons will be stagnant, as long as Datang keeps its more advanced technology strictly secret, at least for a long time, they will not think about upgrading their weapons, then our Datang's advantage will be further expanded. As for our Datang, we have already used the money and resources obtained through 100 steelmaking. Improve and improve our own technology, advanced and advanced! ”

Xia Hongsheng's words made Li Shimin happy. But he still had some concerns, and asked, "What about cement?" There is no substitute for cement, even if asphalt can be used for paving roads, but the yield of asphalt is so low. Elsewhere, cement is irreplaceable. Why did Xia Qing want to sell the cement? ”

"Your Majesty, we don't sell technology for cement. We only sell finished products. Xia Hongsheng said to Li Shimin: "At least for a long time, let them use cement, not make cement." Now the cement ministers are ninety percent sure, and they can't do it except for Datang. ”

"That's not going to work either." Li Shimin shook his head and said, "I have seen the hardness of the walls made of concrete. I have ordered the household department to start budgeting for the cost of replacing all the Chang'an city walls with reinforced concrete walls, and are ready to replace the Chang'an city walls. If cement is spread outside the territory, and other countries have also built cities with this law, wouldn't my Datang be the trouble I found for myself? ”

"That's not a problem, Your Majesty." Xia Hongsheng said to Li Shimin: "First, Weichen will only guide them to pave the cement road, and do nothing else. Second, even if they could draw inferences, they did not know how to build walls with cement, although they had cement - because the walls of a city built with pure cement alone were actually prone to cracking, and Wechen would not let them know the practice of reinforced concrete. Third, the weapons of our Datang siege are also constantly being improved and studied, maybe in the future, there will be no need for people to storm the city? We don't have to worry about what they do with cement! ”

Li Shimin pondered, Xia Hongsheng knew that he was considering the pros and cons of doing so.

After a long time, he saw Li Shimin suddenly raise his head and say to Wang De beside him: "Quickly summon the chief officials of the three provinces to discuss matters here." ”

Hearing Li Shimin's order, Xia Hongsheng smiled in his heart, knowing that this was Li Shimin's heart.

After all, no one would think that they have a lot of wealth, let alone a country. If you can really turn those things that have been exchanged into treasures on the premise of maintaining absolute superiority, in exchange for the property and resources that Datang urgently needs, then why not?

Because it wasn't a mid-year holiday, those bigwigs were all on duty in the three provinces, so they all arrived in Li Shimin's study after a short time.

Li Shimin circulated Xia Hongsheng's recital to everyone one by one, and after everyone saw it, they were all shocked, and then looked at Xia Hongsheng, and some people began to say that it was inappropriate.

Xia Hongsheng told everyone what he had just persuaded Li Shimin to do.

"If it is done properly, the minister thinks that this matter is not impossible." After listening to Xia Hongsheng's words, Du Ruhui, who had never expressed his position, smiled and said: "What the Tang Dynasty lacks now is cattle, sheep, horses, copper, iron, stone grease and water...... Not a lot indeed. It would be a good thing if we could exchange these things for what we didn't want, in exchange for what we lacked. And what Xiahou said just now, as long as Datang still maintains its advantage, then it is not afraid that these things will flow out of the territory. ”

"The minister seconded the proposal." Fang Xuanling also nodded and said, "As Xiahou Fangcai said, these things are now unacceptable to the Tang Dynasty. Selling these things to others who are greedy for these things still doesn't pose a great threat to Datang, and it is not just right to exchange energy for what we need in Datang. ”

Li Shimin thought for a while, then gritted his teeth and said in his heart, "In this case, then Xia Qing will do this in the negotiation with Xue Yantuo." (To be continued.) )
