Li Longji and the three of them looked at the picture and didn't know what to say.

Queen Wang said casually, and Brother Yi gave a method, and sure enough, there was an answer to the question.

"It's not easy to spin, is it?" Li Chengji tried his best to find a place where he could perform.

"Make one first, take a little effort, and I'll measure and calculate it.

Then turn over the mold, and the wood feathers are inserted into the mold, and there are traces, and they are carved according to the traces.

This needs to be calculated, otherwise it is not stable enough, and I will be the first. ”

Li Yi is ready to calculate the arc of the spiral, and then draw it and then carve and turn the sand.

Turn out a metal shell, and the wood can be used to ink the protrusions inside and outside the shell.

If it is not easy to insert, the shell will be split in half and closed against the wood, and the marks will be left.

The wood was then taken out and hand-carved against the lines.

Laborious is laborious, making arrows, even if it is as laborious as a feather, is very demanding, not just take a hair.

When Li Longji saw the drawings and listened to Li Yi's explanation, he couldn't help but sweat.

As Li Chengqi said, Yin damage, broken armor, and the front one remains in the body.

I can only make a cut, find the tail that section, clamp it with pliers and pull it out.

Li Longji looked at his brother Yi again.

Who the hell is it?

Someone offended him and fell ill, and he could be saved on his knees on the ground.

As a result, when it comes to war, things are taken out, and there are arrows that trap people like this.

Li Yi continued: "The front section of this kind of arrow does not need to be polished so well, and the place behind the arrow should be put on some water to make it rust.

The wound is deep, it touches the rust, and it is easy to get tetanus, which is currently only cured by me, and there is a price to pay.

I know how to make the tetanus vaccine, but I ...... More equipment, not now. ”

Li Yi is helpless about this, and if he can't do it, he can't do it.

Then he said: "But I will provide medical alcohol to the front-line soldiers, don't drink it, although you can drink it."

When encountering the same wound, endure the pain, rinse and rinse repeatedly...... Take soap and rinse the wound first, this is better than alcohol and less painful.

Repeated washing with soap and water, followed by alcohol, can save lives to a great extent. ”

"Then soap can't be sold outside, and soap can't be used, I know soap is made out of soap, right, uncle."

When the queen heard that soap could help save lives, she didn't want the enemy to use it.

"Okay, don't export it, yes, don't sell it to outsiders." Li Yi also agreed.

It is said in the newspapers that soap can ensure that the wound does not occur to a certain extent.

At the same time, he said that if you eat something poisonous, you can drink it with soapy water and spit it out, but remember not to hold yourself back.

Actually, you still have to alcohol, and soap can only solve part of the problem.

The point is that soap doesn't sell much and needs grease.

If you don't use oil, then use rosin, which is pine oil.

"Have you ever blown bubbles? With soapy water and a little glycerin, you can blow bubbles. ”

When Li Yi was thinking about the making of soap, he didn't know how to think of bubbles, which was fun.

Glycerin is separated when soap is made, and soapy water and glycerin can make the bubbles more stable.

Because it's alkaline, if it's acidic, there's no bubble.

Like shampoo, it is better to wash your hair every day, and alkaline shampoo is more irritating than acidic and foamy.

The three of them shook their heads blankly.

"Tomorrow night, I'll make it for the kids to play with, it's fun." Li Yi decided to add a toy to the dolls on the Zhuangzi.

As soon as he spoke, the three of them came out of the atmosphere of war.

Li Chengqi took a sip of wine and thought of Yao Chong.

"Brother Yi, is there a way to make mats and straw curtains faster?"

He asked casually, and what Yao Chong said reached his ears.

"Weaving, enlarge the loom, put the bamboo silk and grass, put it on the weaving, remember to wear gloves on the bamboo, so as not to scratch."

Li Yi gave the answer without even thinking about it, what a simple thing.

Li Chengqi wants to laugh, this is the problem that Yao Xiang came up with for the difficult and easy brother?

"I plan to wait for the migrant workers' houses to be built, and when they move in, I will add labor-intensive industries.

This is also one of them, mass production, low cost, low price.

In this way, other people find that it is more cost-effective to buy than to make their own, and they will buy it, saving time and spending it in other aspects. ”

Li Yi had already thought about transforming technology into productivity and increasing jobs, especially for those who did not have land.

"Uncle, when the time comes, pay the taxes?" Queen Wang thought about her family's financial income of the Tang Dynasty.

"Pay it, pay the tax, they won't be recluse, give them renaturalization.

In fact, they are willing to have a place of origin, otherwise their children will not be able to take the imperial examination if they want to.

They don't care when life is hopeless, they can live one day at a time.

When they find that they can have a good life, and the children are still learning, their minds will change. ”

Li Yi talked about the hukou problem, and he didn't pay rent to those people before.

In the future, when everyone has a stable job, what should be handed over will still be paid.

Then he entered Chang'an's hometown, no matter how many people there were, and then built a house on the other side, which did not occupy much land, and the handicraft industry cluster.

The things produced are more cost-effective than the people themselves, and the people buy them and use them, saving time to farm and raise silkworms.

This belongs to industrial differentiation, and even helps the people who farm to harvest and threshing for compensation.

The finer the industrial differentiation, the better the social and economic development, and everyone concentrates on doing their own things.

Li Yi told these thoughts to the three people, and the three of them didn't care about the taste of the food.

Li Longji even wanted to cry and cried.

I was so lucky to recognize a brother Yi, and I actually directly gave the direction of Datang's development.

Everything is so steady, take your time, don't rush, keep pushing.

At the time of internal stability, it also provides external policies and strategies and weapon upgrading.

My family's ancestral grave is buried in the right place, and I must have done a lot of good things in my last life.

As a brother of Yi, he can fight politically, increase the yield of farmland, make a lot of money from business, and study things for fortifications.

It can train soldiers, and can provide soldiers with weapons and meat floss, compressed biscuits and other good military rations.

He can also talk to you about poetry, writing lyrics and music, and enlightening and educating the people.

And make a good dish, and you will be treated when you are sick.

It's so dangerous, my brother is good, I helped find it.

If this was in Tibet, the Turks, or even the Khitan, the result would be different.

The Khitan is very weak, but with Brother Yi, it is not weak.

Not to mention the side, only gunpowder and hot air balloons, he alone can be worth a million soldiers.

Of course, a million soldiers couldn't catch him, he had something to fly and ran away.

Li Longji was glad that he no longer cared about letting Li Yi take the imperial examination as the prime minister.

Being the prime minister has to be busy in addition to a lot of things.

Brother Yi is living a better life now, why bother dealing with trivial issues.

It's a big fart, what if Brother Yi is tired?

Li Longji now thinks that what Yao Chong and they are doing is a big thing.

I don't know how the three prime ministers will feel when they find out.
