"Why?" Li Shimin immediately asked.

"It is mainly due to many reasons, first of all, most of the iron ore we are mining now has low quality reserves, about 35%-45% iron content, which is not a rich ore, and these iron ores are rich in other metals. And the main mining reserves are not high. ”

"Because of the current transportation problems, we can only mine these iron ores with low reserves nearby and use them to build places, and some large iron mines have also been discovered, but many large iron mines are in areas that are difficult to develop, and the area where the large coal reserves are located is also far away from the iron ore."

"According to the planning of the Ministry of Industry, the Ministry of Construction, the Ministry of State-owned Assets and other departments, these areas need to be connected to each other by rail."

"And several state-owned commercial banks on the side of the Ministry of Industry still have plans to upgrade the steel plant, mainly to upgrade the blast furnace, and after the upgrade, the blast furnace will no longer be extinguished even after opening a furnace, and the furnace can even burn for ten or even twenty years." Duan Lun told some of the plans of the craftsmen of the Ministry of Industry.

Li Shimin, they were all a little dumbfounded when they heard it, can a furnace be burned for ten or twenty years? How good this stove must be, they can't imagine anyway.

"I see, but the amount of steel is definitely enough." Li Shimin nodded and said.

"Dad, this is definitely not enough." Li Ke shook his head and said.

"Not enough?" Li Shimin is a little confused, steel production has increased by a thousand times, this is not enough?

"Of course it is not enough, Datang's industrial progress will inevitably reach a certain leapfrog development in the next ten years or even twenty or thirty years, and many places need to consume a lot of steel, such as a large number of cocoons, brand new plows and so on. Especially when more and more people enter the factory to work, there are not many ordinary farmers in Datang. ”

"At that time, don't say that the normal price will be subsidized for agriculture, that is, as long as the money will be paid for every mu of land, it is estimated that there may not be people willing to farm, and we need to reduce the cost of farming at this time. For example, the steam engine in the locomotive, which everyone knows now, was miniaturized and developed into a vehicle. ”

"Such a vehicle can drive dozens of ploughshares at the same time, and can plough thousands of acres of land in a day, and similarly, a machine with a columb, can sow hundreds of acres in a day, so that a family can cultivate thousands of acres, or even thousands of acres of land."

In this way, the cost of farming will naturally drop, and more people will be willing to plough the land when they have more profits. Otherwise, with the development of Datang industry, the income of working in a commercial bank for a month will be much higher than the income from farming, and more and more people will be unwilling to farm. ”

"In addition, a large number of railways need steel to build tracks, bridges need steel, locomotives, train cars, and even steel ships need to be built with steel, and such a huge amount of steel is simply not enough for a few million tons of annual output." Li Ke shook his head and said.

In the future, the annual domestic output can reach more than one billion tons, you can imagine how terrible the consumption of steel is, and now that the land area of Datang is so large, the demand for steel will inevitably rise greatly.

However, the only good thing is that now Nanao Prefecture is under the control of Datang, and the natives above have been cleaned up by the village of Wubu, as long as the situation in Datang is stable, you can immigrate there in the future.

Li Ke's words made everyone in the court stunned and extremely speechless, I'm afraid you are not telling a mythological story? But&...... It seems to make a lot of sense.

Although they don't know anything else, they have all seen the trains, and now the railway from Chang'an to Chencang has almost become a tourist attraction in Datang.

Anyone who comes to Chang'an from other places, those who have money will inevitably take a ride on the railway to experience it, and those who don't have money will go to the vicinity of the railway station to see the railway.

That powerful and shocking industrial power can be said to be a shock to everyone.

Now, when the people near Chang'an see people in other places, they are bragging about using railways.

Therefore, the locomotive can drive such a terrifying weight of goods and carriages forward, as if with some ploughshares, and cocoons, there is no problem with plowing thousands of acres a day?

It's just that they can't figure out what to do with these things.

"It seems that the development of our Datang is now far beyond that of other countries, which is a good thing! Meddlesome! Li Shimin said happily.

But although his face was happy, Li Shimin was startled in his heart, good guy, has the current Datang developed to such a point? Fortunately, I have laid enough groundwork, and this kid doesn't know much about it at the moment, otherwise, in a few years, it is estimated that this kid will not be able to do anything.

At that time, even if his plan is successful, this kid may have some backhand, and now these things can obviously still interfere with his hands and feet, otherwise, the consequences will be unimaginable!

Good guys, this stat temple is good, it looks like I know more about this.

"That, the Ministry of Agriculture." Li Shimin said directly.

"The minister is here." A minister about forty years old walked out, and it was the eldest grandson of the eldest grandson of the eldest grandson family.

"Just now I heard from the Statistics Temple that the consumption of staple food by the people near Chang'an in Datang is declining, but the consumption of staple food in Datang is rising nationwide, what's going on?" Li Shimin asked the question he was interested in first.

"Back to Your Majesty's words, the minister has learned about the relevant issues, because the people near Chang'an have become rich, and now there are people who grow rapeseed in all parts of the Tang Dynasty under the arrangement of His Royal Highness.

"There are many people who have become rich first, and they can even kill a pig a year, enough for a family to eat for a year, and the consumption of staple food will decline after the people can eat oil, water and meat."

"We have learned from various state-owned commercial banks that in some iron mines, coal mines and other mines, the people working in these places are heavy coolies, and if there is no oil and water, they can eat an average of three catties of staple food a day. Some are so strong that they can even eat four catties. ”

"But if they are supplied with some meat, especially some meat with more fat and oil, they will eat one pound of staple food and one pound of meat with vegetables and potatoes a day, and they will basically be full and meet the needs of a day's work."

"And the people's consumption of staple food near Chang'an also went through a point of increasing and rising, and then began to decline again."

"At present, the consumption of staple food is rising nationwide, mainly because the people were not full before, and now they have the conditions to eat enough, so they naturally eat more, but potatoes, which can be called the fairy varieties taken out by His Royal Highness, are also unparalleled in assisting Datang, mainly because it does not pick the ground, and the demand for water is also less, but the output is quite good, which makes Datang absolutely starving people in the future."

The eldest grandson Zhiren obviously knows more about this aspect, and directly gave Li Shimin's answer.
