Li Yi stared at Song Jing, Song Jing did not evade at all, and glared.

The two looked at each other for a while, and Li Yi smiled: "Isn't it the soldier who wins right now?" Place occupied. ”

"Don't you need to keep it?" Song Jing finds fault.

"Longyou didn't keep it before? Hexi Jiedu is not kept? It's just that the soldiers guarding the two places are put in front to guard, what's the difference? Li Yi was reasonable.

"Of course it's different, the distance is long, and it is difficult to transport the baggage." Song Jing finds the key problem.

"Shipping was better before than it is now? Is it faster, or is it shipping more stuff? Li Yi asked with a grin.

"Isn't that because of you, how can they supply without you?" Song Jing is right.

"Oh!" Li Yi nodded, and at the same time clenched his fists to express his gratitude.

Others looked at Song Jing and didn't make a sound, they just watched.

Song Jing clicked his mouth: "The source of the Yellow River also needs to be heated in winter, how can there be coal mines?" ”

Li Yi took out a map beside him, spread it out, and pointed to several places: "There are coal mines here." ”

He pointed to the position next to him: "Six hundred miles away from here to Sister Lake, there is a large open-pit coal mine, which is occupied by Tibet. ”

Li Yi was referring to his open-pit coal mine in Haixi Prefecture at the time, north of Sister Lake.

At present, there are still Tibetan armies and tribes, but they are not fighting south.

Several other locations are in the place controlled by Datang, where Longyou, and a little further west, are small coal mines, which are not easy to mine.

Coal reserves are small, it doesn't matter, enough to dig locally, digging a few hundred meters deep is the problem.

"There's gold and other mines here, like antimony, tungsten, I don't know what they are, right? Good stuff.

I can use it to make alloys, and I can also make safety matches, which I haven't taken out all the time, and if I produce them, it's easy to make people sick.

If you don't want to be poisoned, you can only continue to increase the process, and the fire sickle you are currently using is good, so let's use it first. ”

Li Yi felt that if he was on the match production line, it would be better to use that technology for something else.

The fire sickle of the Tang Dynasty works, and it ignites the fire with a skillful stroke.

Flint is generally white stone, and there was a white stone ditch near Li Yi's home when he was a child, and there were many such stones in it.

The main ingredient, silica, can be ignited by rubbing it.

There are also matches inside, which are not worth much.

To make matches, you need to make red phosphorus, and it's hard to get red phosphorus, why make matches?

Looking at the picture and listening to Li Yi's words, the three prime ministers were silent, feeling bullied.

Yes, they admit? I don't know what Li Yi is talking about.

The only thing known is that there are mines? Coal mines, gold mines.

The gold mine was left unattended and could not be used for the time being, and the coal mine kept the soldiers warm in winter.

"Coal mines allow people to dig?" Bi Gou didn't want to see Song Jing deflated.

"Now where the cement is burned, the people will dig it? Some of them kept for themselves, and some of them went to the cement factory for the money from digging coal. ”

How many small pieces did Li Yi draw on the map? That's where the cement plant is.

It was not painted elsewhere because there was no stone to burn cement.

Su Ying thought about it? "There are few local people, and the coal sent to the front should be washed bright lump coal." ”

"There are captives, don't plan to put them back now, hurry up and send them to Longyou." Li Yi reminded.

Don't always worry about letting the people do hard work, the people still have to farm and breed.

Tens of thousands of captives? Swap the people of Datang back? The rest is all washed coal and burned cement.

You can't just eat and not work, people have the right to work.

"Tune it, transfer the captives to the past, and give Anxi the money to make money? Brother Yi, you buy the captives. "Li Longji knows what Anxi Jiedu is waiting for.

Waiting for money, as well as medicines and tools for the treatment of injuries and diseases? Gauze, scissors, alcohol, etc.

Li Yi agreed without thinking about it: "I will pay and send someone to send the exchange vouchers and materials, and the lost money will be deducted from the tax." ”

"Let's deduct it next year, you have to collect 30 million yuan this year, and you finally sold things and paid a lot of taxes."

Bi Gou whispered that he wanted to see that there was enough money on the books.

Other shipbuilding and railroad rails can't be spent much now.

10 million yuan to build a ship, and it is not a time to take out 10 million yuan.

Buying things one after another, hiring people, and granting funds in batches.

He knew where the money Li Yi lost was, and the prisoners he bought spent money.

Washing coal and burning cement, who will give Li Yi money?

Li Yi also had to pay for the captives to eat, which was another burden.

"Xiao Yi, the old man knows that it is not easy for you." Bi Gou was relieved again.

Li Yi blinked: "Where is it not easy for me?" You say money for food? I told the captives to beat the coal billets and shake the briquettes with coal faces.

A hundred coal billets, a penny, are the people willing to buy it? Don't buy them, pull coal face and go back to fight.

If you buy it, you can directly pull the coal billet in the past, and a captive can beat 3,000 coal billets a day, which is less, 5,000, and the proficiency will be fast. ”

Li Yicai is not worried, washing coal, a captive must wash out a ton of coal a day.

In a group of two, 2.5 tons of coal a day will be rewarded with broth to drink, and 3 tons of meat to eat.

Less than two tons of hitting, the rice is halved, less than a ton is there an opinion, planing the pit buried.

Even if it is 150,000 front-line soldiers, how much coal can be used in a day? One person has ten catties of coal, which cannot be burned.

The stove was kept burning all day long, and it was kept burning for twelve hours.

Eight people in a room, eighty pounds of coal, no one can go on the kang, it is too hot.

Not to mention the fire kang, you can't stay in the house at all.

On average, a captive washes out one ton of refined coal a day, 30,000 captives get 30,000 tons, and the other 40,000 or 50,000 go to dig coal.

For a month, it was enough for the soldiers in front.

If you are in a hurry to burn cement, you can wash coal by 10,000 people, dig coal by 20,000 people, and grind cement by others.

After two or three months of washing, my own place is enough.

After a few days, the weather was cold, it was difficult to wash coal, and the water was cold, and normally Li Yi's coal washer at that time would not work.

Captives don't need to think about whether it's cold or not, they wash coal and ice holes like in winter, and they can wash it with water!

"Xiao Yi, according to this...... Pay some taxes, right? "Bi Gou pondered it, and the captives dug coal, washed coal, and beat coal billets.

When the supply is finished on the front line, take it out and sell it, and one person can provide Li Yi with thirty or forty yuan a day.

The more than 80,000 captives in the two places combined earned Li Yi 3,000 yuan a day.

30,000 in 10 days, 300,000 in 100 days......

"Buying captives is not money? It needs to be paid in batches, a captive is fifty ta, more than eighty thousand, and only one million is earned a year, and the capital is returned in four years. ”

Li Yi was aggrieved and couldn't let it go anymore.

His current more than 12,000 captives basically work in vain, regardless of the court's request for money.

Bi Gou just nodded, and suddenly shook his head again: "Twenty-five percent a year is too little, you?" Let me give, my household has money. ”

"Okay, here you go." Li Yi is as good as a stream, you have the ability to make money, I don't want it.

"Then you give me ideas, I can guess, you will use them to pay for money faster."

Bi conceived how to make money, and digging coal and washing coal guaranteed not.

Li Yi looked at him: "I owe you?" ”

"Okay!" Bi Gou nodded, there is money to be made, what kind of face do you want.
