"The Anxi Jiedu envoy was afraid of the lack of local troops, and Sulu looked for an opportunity to fight, so he took the initiative to send troops to attack instead of defend."

Li Yi pondered for a while and guessed the reason.

In the early days of the Kaiyuan Dynasty, the generals of the Tang Border Pass lacked logistical support.

As long as the food and grass are sufficient, the generals are more powerful than the other.

Seeing the autumn harvest and the Anxi soldiers finished fighting, Sulu promised to be honest, but Sulu didn't know that Anxi had used all the explosives.

Anthy finished beating people, grabbed things, and came back just to be a bumper harvest.

"Many officers will be sealed." Another reaction of Li Longji to the victory of the fighters was to spend money.

The minimum rank of the commander is seven ranks, without any real power, and they are given according to the ranks.

When there is no money, divide the land, and give a few acres or dozens of acres of the land that has been beaten down or the local land.

When there is no land to seal, and there are many people with the commanders, things will be in trouble.

"We Datang have money, it doesn't matter if we pay a salary, we will occupy more land and make money with land, and our financial income will continue to grow."

Li Yi didn't say that the occupied land would be sealed, and the soldiers would fight in the future, and they didn't want to farm.

……

Political Affairs Hall, today's king is not early, and Song Jing's state is slightly worse.

"Send troops privately, even six cities, and one day send troops to Chang'an privately." Song Jing was most opposed to the blind beating of the generals outside.

That's the reason why he suppressed Hao Lingquan, but it's a pity that his words don't work now.

"After fighting Sulu, Sulu did not dare to send troops this year, so he could only go to fight the Turks and white-clothed food to replenish the losses."

Su Ying, the secretary of the military department, doesn't think anything, just fight, as long as he wins, everything is easy to say.

"What kind of ability is it to bully people with explosives bags? Fight, and naturally win. Song Jing complained.

Bi Gou smiled and didn't speak, he wanted to say that he would give you a dynamite bag for you to fight.

"Xiao Yi said that he wanted to build the railway, so I didn't spend the money too hard, the financial income of 30 million yuan is actually not much."

Bi Gou is worried about the logistics of the Anxi Jiedu envoys, and at present, they don't need to give things, they rob them themselves.

It is estimated that there are a large number of sheep and horses, and the so-called six cities are connected to the city, and the city is a small city, with a wall of mounds, and the wall is not as high as a zhang, and it is thin.

If a dynamite bag goes down, a section of the wall will inevitably come out of a big hole.

Changed to the outer city wall of Chang'an City, a bag of explosives went down, and there was no response.

Chang'an City is three zhang and four feet high, the top is about three zhang to three zhang and five feet wide, and the bottom is four to five zhang wide.

Counting the thinnest thickness, nine meters thick, how do you blow it up with an explosives pack to blow it up?

However, it is useless that the walls are thick, and they should be occupied or occupied, and the country should be destroyed in the same way.

"If all 30 million of them are used to attack Tibet, can they destroy Tibet?" Su Ying thought that it would cost a lot of money to build the railway, and thought it was not worth it.

Spend 10 million yuan to repair the railway, and build that locomotive, maintenance costs money, don't you need money for the train to go?

How many years will it take to earn back the money spent?

Su Ying didn't know that once Li Yi built the railroad tracks from Chang'an to Luoyang, there would be almost no problem of recovering costs after the train began to operate.

In addition to the money earned, it is used to maintain the existing rails, and the rest of the money continues to build and lay rails.

Li Yi will build the railroad track from Luoyang to Haizhou, that is, Lianyungang, because it is close.

Once the railroad tracks were from Haizhou to Chang'an, soon the railway began to make a lot of money.

The sea transport is directly to Haizhou for loading and unloading, and then to Luoyang and Chang'an, two important places in Datang.

On the Grand Canal, there are also docks for loading and unloading, which run down the water or up below.

Su had no idea how much profit he had, and those profits continued to be used to pave roads, build bridges, and increase taxes.

The profitability of the railways is not visible, but the financial side has been supplemented.

……

At noon, the Li family Zhuangzi ate snake meat, and Li Longji and his family were all together.

Princess Yongmu ate the meat from the plate with a happy face.

She didn't care what she ate, she felt that she was happiest to eat the braised snake meat she had said last night.

"Brother Yi, the 10 million money for repairing the railway, the court wants to take it out now?" Li Longji did not go to the court and decided to ask something serious.

Isn't this equivalent to going to the court, I am asking about politics and not resting.

Li Yi swallowed the rice in his mouth: "Early, there is good steel, I also have the technology, prepare for the steam engine ship and the locomotive to be built at the same time, I am too tired this year, my farmer." ”

"I really can't, set aside next year's budget. You print more vouchers and make up for them when the time comes. ”

Li Longji thought of a way to consume at a deficit, and normal people would have such thoughts.

Li Yi smiled: "No, 10 million, there is not much money on the rails."

Iron ore mining, including transportation, is a labor cost that pays wages.

Coal mining, coal washing, transportation, or wages, no one wants to make a profit from it.

I'll build a few more furnaces, and let Yulin Feiqi help to directly tap the steel and cast the rails......"

Li Yi estimated that the cost of about one mile of land was 2,000 yuan.

He couldn't get out of the rails, so he had to cast, make the mold first, pour molten steel into it, and break the mold after cooling.

The labor cost of two million yuan per mile, this money has not been thrown away, and the money earned by manual work has to be consumed.

If you don't need money, the cost can be lower.

The cost includes sleepers made of cement and wood, crushed stones, etc.

It is also not easy to cut down large wood, soak asphalt, make cement, and burn crushed it.

10 million is enough to repair 5,000 miles, that's 10 billion dollars, and the purchasing power is terrifying.

Actually, no, there needs to be a track split, a turnout.

The train traveling in the opposite direction is divided into two railways on a certain section and the wrong train passes, and the two ends move the turnouts, and it becomes a monorail.

You need to calculate the time, otherwise you will bump into it.

As for the double track, there are not so many trains, it is not cost-effective, and it can be added in the future if economic development needs.

Counting the locomotives and carriages, 10 million yuan is enough to repair from Chang'an to Haizhou, including the railway bridges over several rivers on the road.

After listening to Li Yi's calculations, Li Longji breathed a sigh of relief, it turned out that the cost was within the affordable range.

10 million looks very anti-flower, not bad.

He had forgotten the fact that the total financial income of Datang in the past few years was several million, and those money and things were enough to maintain Datang's expenses, including the war.

Now 10 million is only enough to build a road from Chang'an to Haizhou.

"When it's repaired, if you want to eat seafood, let the train run a special line, which can run about 120 or 30 miles every hour.

At this rate, it will take less than 20 hours to get from Haizhou to Chang'an.

If the station is set up, the train starts, brakes, waits for loading and unloading, starts again, and brakes again, and the speed is slow. ”

Li Yi is talking about the kind of car that stops and waits.

In the past, the real speed of the car was not slow, as long as it did not stop in the middle and kept running, the speed would go up.

Stop once, the inertia is gone, start again, slowly speed up, drive out for dozens of miles, and stop again.

Every time you stop and start, you need to consume a lot of fuel, and the wear and tear on the car is not small.
