Li Shimin's fanaticism for trains can be seen on Liu Mu, but!

Liu Mu shook his head helplessly: "Without a locomotive with 1,200 horsepower, you can't pull the train at all." It doesn't make sense to take only a few carriages, and it loses the meaning of the train's super-transport capacity. And our Datang steel mill still needs to be built, this train uses steel rails, and it requires countless steels, countless ones. ”

Li Shimin asked Liu Mu: "Build a few more large steel mills." ”

"There's a plan for that."

After Li Shimin pondered: "You need a plan, you are not wrong, it is better not to let the courtiers know for the time being, this kind of thing is like a large and small general cannon, which has a huge impact on the national fortunes of the Tang Dynasty." I think of my cousin, digging a canal to conquer Goguryeo and ruining the Great Sui. ”

Liu Mu didn't answer, because in his eyes, Emperor Yang of Sui was actually a very powerful figure like Li Shimin.

There are so many similarities between the two.

But there is a huge difference in key places, Li Shimin cares about people's livelihood and is very diligent. Yang Guang is not, just looking at the number of people in his harem, the scale of his patrols, etc., and the time he has been in Chang'an for many years in power has not added up to a year.

"According to what you said, if you are desperate to build the railway, I am afraid that Datang will not be able to afford it."

"Yes, after the steel production is increased by another thirty times, and the treasury revenue is increased by another three times, it is not too late to repair it."

Liu Mu believes that the minimum guarantee for the construction of the railway is that Datang has an annual output of more than 300,000 tons of steel, and Datang's treasury can reach at least 60 million yuan in income before the railway can be built.

But it's a good thing to use it on a ship, it's a yarn mill, it's a good thing to use it in a mine.

Anyway, the steam engine used in the train, Datang can't build it at the moment, and the ship is already at the limit of Huayuan, and it is not a big enough ship, and it is only used as a tugboat.

A real steamship hull needs to be at least fifty meters over.

But at present, although the big belly tank ship of Datang is more than 70 meters, the internal structure of this kind of ship is estimated to fall apart when the steam engine is installed, and it must be strong and have enough capacity, and it must also have the position of the steam engine and the transmission device, and a very good structure is required to ensure the stability of the hull.

Datang's shipbuilders still need time to study and better hull structure.

Liu Mu doesn't understand, he only knows a rough idea, which can make Datang have 500 full-sail sea ships, which is already the limit of Liu Mu's help to the shipbuilding industry. The next step is to provide the concept by the excellent craftsmen of Datang to continue to study and try.

The Tang Emperor Li Shimin, like a primary school student, tirelessly asked about the train.

It wasn't until Yanagi explained that he felt that he had no words, and finally stopped.

Li Shimin was also tired of asking, poured a cup of tea, sat on the chair and said to Liu Mu: "Mu, there was something in the palace that day that was not mentioned, Huating County is your fiefdom, and the opinion of the original household department is that Huating will deduct seventy percent of the revenue from the treasury, and the rest will belong to you." ”

"Tobe...... Is Cui Junsu stupid? ”

Liu Mu's words made Li Shimin laugh, it was obvious that Liu Rucunyu was telling the truth, and Huating's income would be a terrifying number.

Liu Mu said: "Of the four major ports of Datang, none of them can be handed over to anyone. In the era of maritime trade, the annual net income of any port will exceed the current treasury revenue...... several times. ”

"The Four Great Harbors?" Li Shimin's eyes changed.

The four major ports all exceed several times the revenue of the national treasury, which does not mean that Datang's treasury will have ten times the income.

Liu Mu said: "The top two, Super Palembang, are Huating and Guangzhou Port. In Huating and Guangzhou, ten wharves of various sizes will be built, and the daily cargo volume will exceed 100,000 stone in three years. ”

One hundred thousand stones is five thousand tons of the Hereafter.

Is it much?

Huating was called the magic capital in later generations, with an annual swallow of nearly one billion tons.

"What about the other two?"

"There is a small fishing village next to Yanzhou, which is very suitable for building a port, where Shangyingkou and the upcoming Beisha City will be the most important port group in the north and the distribution center of goods in the north. There will be no less than 50,000 stone of goods per day. The last one we haven't occupied yet, it's the most important port of the future. ”

"Where?"

"Further south of Guangzhou, almost tens of thousands of miles away, there is an entrance to the strait, and the person who controls that entrance will control the ocean of 50,000 li in Fang Yuan."

Li Shimin nodded slightly: "Okay, then control him." Let's talk about Huating, your second mother said that she would only give you five thousandths. ”

"It's a lot. There are too many, and some coins are taken too much, and it is estimated that people will be hated. To tell the truth there, I don't want the second brother, it's a mountain of gold, and whoever dares to monopolize it is a thorn in the side of countless people. ”

"Huating, is it really so powerful?"

"Second brother, Huating is equal to the most important port for goods to go to sea in the south of the Yangtze River, and Huating West will build countless workshops to process foreign raw materials into high-quality goods and then sell them, plus the goods in transit, this amount will make everyone red, I like to make money secretly, not on the cusp of the limelight."

Liu Mu's words were reasonable, and Li Shimin said after thinking about it: "Then, I will change it for you." ”

"Sanjiangkou. The Juzhang City of the former Sui Dynasty now seems to be called Cixi County. ”

This place is the later Ningbo, the southern corner of Hangzhou Bay.

"Yes, the second brother in that place remembers that the surrounding counties are all lower counties, and none of them has more than 600 households." Li Shimin was worried that that small place would not be able to make a lot of money at all.

Moreover, there is Huating Port, and it is impossible to build a second big port in that place.

Li Shimin said again: "But this kind of thing, you go to the table yourself, and then Shangshu Province will discuss the matter, and the second brother does not plan to participate." It doesn't matter if you change it or not, unless you insist on it. ”

"It doesn't matter if I change it or not, but at that time, I dared to ask for one thousandth at most, this is the limit. No matter how much it is not suitable, if it is thirty percent, don't let me stick to the Huating tariff, I can build a few workshops with peace of mind, and thirty percent is no problem. ”

"If so, the treasury will collect a maximum of 20 percent of the tax. Discuss this matter with the household, the officials, and the rites. In addition, the accounts of the four northern counties are listed separately, and the expenses of the Ghost Labor Valley are accounted for separately. The supply to the palace and the god guard must also be accounted for separately, and the extra part will be handed over to the Ghost Worker Valley, but the account cannot be less. ”

"Understood." Yanagi really understands.

The four northern counties are in Chang'an, which can be used as a supplement to the royal income and expenditure, but not as part of Liumu's personal income, so Liumu will be given another place.

All this, Yanagi can understand.

However, Huating is indeed too eye-catching.

Li Shimin and Liu Mu chatted for an afternoon, and in the evening, the eldest grandson Wujian also came over and had dinner here at Liu Mu.
