Da Tang: Three days later, I was frantically collecting supplies

If someone works for the iron smelting, Li Kei can rest assured.

Iron is used as a material for guns, and copper is needed for bullets.

It’s a good thing to say that copper was cheaper than iron in this era.

Because the purer and softer, not as hard as iron.

So copper should be more suitable for bullets, Li Kei doesn’t know why, anyway, everything I have seen on TV is copper.

It is estimated that it is high precision and does not rust.

The inside of the bullet was also studied, there were too many types to distinguish.

The bullet turned out to be copper-clad lead, and even steel-clad core.

The bullet casing is also alloy copper.

I simply read the book and confused myself again.

Sure enough, science is something that is not intoxicated to study well for a few months, and it really can’t get results.

Forget it, anyway, others can’t understand that I made bullets, so it doesn’t matter if you let the next person do it, and it doesn’t matter if you build them one by one.

As long as the size is right, you will be good to go.

Then Li Kei left it alone again, almost skipping this link.

Getting bullets is bound to be inseparable from gunpowder.

Ordinary black powder will not work, so add some white sugar and try.

In the past few days, Li Ji pondered how to brazenly develop gunpowder, and suddenly remembered fireworks.

It’s winter, and it’s almost the New Year.

I’m not too much to make fireworks, right?

But recently, the weather has been cold, and Li Kei is too lazy to go out of the house.

Simply find someone to buy some saltpeter, sulfur, plus the house has already hoarded charcoal.

Li Kei found a hut and began to develop gunpowder.

After trying several times, Li Ke’s strict proportion configuration in the book is still unsatisfactory.

It’s okay for this thing to ignite the fire, and the detonation is enough to choke.

If you think about it, you can understand the reason, probably because the purity of saltpeter or sulfur is not enough.

So, in a few days, Li Ke’s trial and error finally made a bunch of fake explosives, which could be used.

Just as he was about to go to the steel mill to get some bullets and bullet casings, Xiao Man ran over.

“Your Highness, it’s not good, Princess Changle is sick! Go check it out. ”

Li Kei was shocked.

No wonder I didn’t bother me these days, it turned out to be sick.

“When was it, why did you tell me now?”

Xiao Man said: “Her Royal Highness is a little uncomfortable these days, saying that you are quite busy and did not bother you.” It would be nice to think about resting for a few days, but today it turned out to be even more serious. ”

Li Kei hurried over.

I saw Changle covering his lower abdomen, moaning constantly, and sweat on his forehead.

Li Kei immediately stepped forward, touched Changle’s head, compared his own head again, and wondered: “No fever?” What’s going on? ”

Changle Ping retreated, and then whispered to Li Ke: “Third brother, I may not live long, I will die of pain…”

“What nonsense, did you find a doctor?”

“I found it, the doctor asked me to drink more hot water.”

Li Kei was stunned.

Drink more hot water?

What is this?

Li Kei suddenly understood, this is a disease, this is just painful menstruation.

In the past two days, the weather has become cold, and there is no heating in the house, which is why it has become so bad.

Li Kei suddenly realized that he had to think of a way in winter.

Accustomed to the heating and air conditioning of later generations, this must not freeze like grandchildren in the cold winter.

Seeing Changle’s painful dead and alive appearance again, Li Kei was also a little distressed.

The great aunt is a woman’s lifelong enemy.

It is also enough to suffer if it can hurt to this realm.

“Startle me, I thought you had something really sick! You wait, I’ll come when I go. ”

After that, Li Kei went back to the room and found a box of painkillers and a pack of sanitary napkins.

This thing has to be saved, and when the grain problem is solved next year, the cotton can basically be planted on a large scale the year after that.

At that time, open a paper mill, and then you can do it in batches, don’t have a template at that time, it will be troublesome.

After thinking about it, she asked people to boil a pot of hot water again, ready to fill a water bladder for people to cover her stomach.

“Here, eat it.”

Li Kei didn’t talk nonsense, went into the house and brought a glass of water and handed her a painkiller.

Changle was stunned, saw the capsule in Li Ke’s hand, and was taken aback.

“Brother, you dreamed of immortals again? Why is the medicine yellow-red this time? ”

“You don’t have to eat if it’s not in pain.”

“I eat, I eat!”

After speaking, Changle swallowed the capsule into his mouth, then poured a mouthful of water and went down.

After eating, Changle continued: “Third brother, it still hurts!” ”

“How can it be so fast, just lie down for a while!”

After a while, Xiao Man sent a warm water bag, and Li Kei stuffed the warm water bag to Changle.

“Give, cover yourself a little, such an adult, I don’t understand this thing!”

Changle grinned and lay down quietly.

Later, Li Kei arranged for Luo Die to teach her how to use sanitary napkins.

Li Ke: This is being a brother and a father again.

Back in the room, Li Kei sighed again.

I have to find a way to heat up, which is also a big project!

In previous years, heating was burning charcoal, which heated quickly and had quick results.

Even if the fire is in the house, a little smoke, and it is easy to gas poisoning.

Li had to turn his attention to coal.

This thing is burn-resistant and generates a lot of heat.

The disadvantage is that the taste is large, the smoke is too large, and it is easy to smoke people, so fewer people use it.

However, later generations solved this problem well, that is, the heater burned coal, and the stove was set outside.

Through the pipe, water is filled and made into a radiator to heat the room.

Some have also changed to burnt honeycomb coal for convenience.

However, the sky is already cold, and it is impossible to dry out honeycomb coal, and wet coal is easy to get gas, so it is simply burned bituminous coal, commonly known as Shanxi Datong block.

Speaking of radiators, that requires iron.

Li Kei suddenly thought of something.

“By the way, isn’t that Geng making steel? Who knows what happened? ”

So, Li Kei took Hao Jie and hurried to the steel mill.

I saw that Zhao Rui was arranging people to work.

Worthy of being a professional, the blast furnaces, bellows, crucibles, etc. seen in these books, this guy actually made them.

Seeing Li Ke’s coming, Zhang Jinbiao looked overjoyed and said, “Your Highness, I didn’t expect that the book you gave me was really useful, and Xiaguan has successfully smelted molten iron.” ”

Li Ji was overjoyed and asked, “Is it, hurry up and let King Ben take a look!” ”

After speaking, Zhang Jinbiao took Li Kei to see the fruits of his labor.

“Your Highness, although these are not yet usable, they are already much stronger than the original iron tools.

Moreover, the subordinate also obeyed the orders of His Highness and bought iron ore. ”

Li Ji excitedly touched the newly refined steel, and his heart was very happy.

These are still a little bit of a cylinder block, but for heaters, stoves and radiators, it is quite suitable.

So he patted Zhang Jinbiao’s shoulder and praised: “Not bad, do a good job, Ben Wang makes a mold, isn’t it a problem for Ben Wang to use these iron tools?” ”

“Your Highness, look what you said, isn’t this steel mill all yours, what do you like to do!”

“Well, melt all this, and King Ben will make a warmer.”
