Li Shimin's will: Li Zhi, the throne belongs to your brother

The concubine once thought that maybe she would die in the palace like other talented people, ignoring the red flowers and willow green outside the high wall all her life.

However, compared to the ordinary people, the old dead palace is also good.

My father once said that every disaster year, the mountains and plains are full of disaster victims.

As far as the naked eye can see, the bark and grass leaves have all been eaten away, and the bare land can be seen thousands of miles away.

Among the disaster victims are often the strong men, and the rest of the elderly, children, and women are all rations.

I don't have to worry about the pain of ordinary women, and I should feel lucky to be able to marry His Highness and find a confidant.

It's just that I feel inexplicable in my heart, so don't worry about it, Your Highness. "

"Yes." Li Tai nodded.

He knew that Wu Meiniang said that she didn't dare to expect extravagance, but she had other ideas in her heart.

Li Tai didn't know what it was exactly.

"If Mei Niang is still puzzled, you can ask me.

With my intelligence, I will definitely give you an answer. "

"Concubine~ Got it." Wu Meiniang got up and changed the subject: "Husband, what do you need a concubine for?"

"The construction of blast furnaces requires iron ore, coal mines are called stone mines, and limestone mines have limestone mines and water.

Also consider worker housing, horse transport, and more.

Now, I wanted to make a sand table according to the land deed and choose a good place to build.

But I didn't expect that there was no relevant map.

I wanted to hand this matter over to the steward to investigate the surrounding area of ​​the mine.

I didn't expect you to come, Mei Niang. "

Wu Meiniang nodded and said: "I see, I understand.

The concubine will definitely arrange this time for His Highness. "

After finishing speaking, she frowned and asked again: "It was His Highness who informed this concubine at this time. If His Majesty knew about it, wouldn't you blame your husband?"

"No, the blast furnace cannot be concealed from the eyes of the world, but the inner world is not so easy to penetrate."

Li Tai smiled and explained.

The blast furnace is five meters high and has a cylindrical shape. Such a strange shape can never be hidden from others.

But the internal structure, as well as chemical reactions, etc. are difficult to reproduce without drawings and knowledge.

The technological content is still very high.

Just knowing the shape and materials, even if you build it yourself, if you don't pay attention, it will explode and be cremated on the spot.

"Don't worry, Your Highness, Mei Niang will definitely help His Highness complete the blueprint."

With that said, Wu Meiniang twisted her waist and left Li Tai's embrace.

"Do your best, don't tire yourself out." Li Tai explained casually.

After explaining the matter to Wu Meiniang, Li Tai began to specify various indicators.

Indicators for measuring materials, such as strength, hardness, plasticity, toughness, etc., need to be formulated.

After making these things, you can start making lathes.

The lathe is also known as the mother of industry. With the lathe, various machines can be manufactured, including steam engines.

The steam engine looks very simple, but this thing is a test of the performance of the material.

The working environment of the steam engine is very harsh, pressure, high temperature, water vapor and so on.

These are quite a test of the performance of the material, and if one fails, it will be blown up for you on the spot.

Therefore, it is very necessary to make standards for measuring materials.

In addition to the properties of the material, consider heat transfer, power, lifetime, and more.

Then build a model to calculate how to use the least amount of material to achieve good efficiency.

This is the general approach to problem solving, asking questions and experimenting to solve them.

Then constantly summarize experience, finally build a model to get the best results, finally verify, and repeat.

In the end, a perfect answer can be obtained.

After many experiments to obtain data, a qualified steam engine is considered complete.

It took decades for the steam engine to go from the model to the use, and then to the large-scale industrialization.

But it is much more convenient to have the blueprint in mind, and a qualified steam engine can be manufactured after several experiments.

But before that, if a worker wants to do a good job, he must first sharpen his tools!

Need to get out the pencil and eraser.

This quill pen uses ink water, which is easier to use and easier to obtain than a brush, and it writes very delicately.

But like a writing brush, it has one of the biggest disadvantages, which is that it is not easy to change.

In fact, ancient literati also had erasers and correction fluids.

When using bamboo slips, just use the 'book knife' to cut off the wrong characters written.

But now that paper is used, it is definitely a hole.

Thus came the correction fluid—orpiment: the orpiment that slurs.

This thing is delicate and can be faded. At the same time, it will stick firmly and not easy to fall off, but it cannot withstand repeated alterations.

Don't expect to be able to draw with this thing.

But the pencil lead of a 2b pencil is made by mixing graphite and clay in proportion.

The eraser is made of rubber.

Graphite mines are hard to find, rubber trees are still in America, and plastics made from petroleum are still in the ground.

The only ones that can be used are charcoal pencils and steamed buns.

Charcoal Pen can find a random willow tree, and when there is no eraser, it can only find a steamed bun as an eraser.

The problem of the charcoal pencil and the eraser problem is barely solved.

Then there are rulers, compasses, and pens, all of which have to be made by goldsmiths.

With the tools at his fingertips, Li Tai was a little more satisfied.

Looking at this golden ruler, golden compasses, and golden fountain pen... Li Tai feels extremely luxurious.

First draw some basic structures, gears, connecting rods and so on.

Chapter 36 Are you a fish alive?

On the other side, after Wu Meiniang got the order, she didn't immediately order someone to investigate, but came to Jinghe River.

It is said that not long ago, this river was still a nameless river.

But later, some people who collected herbs in the mountains saw the birth of the Dragon King, and got his own name——Jinghe.

According to the people who collect herbs in the mountains.

At that time, the emperor came to the river beach with a team of people.

It didn't take long, only to hear the sound of bombing, and all the beasts fled in fright.

He suddenly felt a tinnitus, and an invisible force passed over his body, and goosebumps all over his body stood up.

Looking back, the smoke and dust rising into the sky from the bank of the river curled up, like a dragon or a snake, changing and invisible, and finally blown away by the wind.

The herb collectors hurried down the mountain to take a look.

From a distance, I could only see the twitching and dead horses, and the huge pothole left by the river bank.

There is also the imperial forest army covering up the traces.

Not only the herb pickers heard it, but also the river below, many people picked up the white-bellied fish.

Many people didn't believe it, but under the leadership of the herb pickers, they found a lot of horse manure, horse urine, and broken pebbles.

The soil in the pothole has a peculiar smell.

Many people were shocked by this.

Some people say that the emperor just killed an evil dragon, the horse was scared to death by the dragon's power, and the dead fish is the son and grandson of the dragon...

The rumors are ridiculous.

But it spread quickly, and quickly became a fun thing for Chang'an people after dinner.

Soon, a Dragon King Monument and Dragon King Temple were erected here.

The fish here is called Jinghe fish, and the price is more than ten times that of other places.

"Jinghe fish, there is always one, sold cheap and bought cheap."

cried a fishmonger.

In front of him was a straw mat and a wooden barrel.

There are many fish that have been cut open on the straw mat, and there are many live fish in the wooden barrel.

Wu Meiniang walked over and stopped in front of his booth, the fishy smell made her feel a little uncomfortable.

she asked, twitching her nostrils.

"How much is your fish?"

"Ten cents a piece."

Wu Meiniang frowned: "So expensive?"

The fisherman said depressedly: "Hey, Miss, there are no Jinghe fish here!

These are Jinghe fish that my son just brought up from the river. "

"Well, give me two!" Wu Meiniang said directly.

When the fisherman heard this, his face immediately became overjoyed: "Oh, that's great, I'll kill them all for you."

Wu Meiniang smiled and said, "No, no, what I want is this bucket of live fish."

"Live fish?!" The fisherman was stunned, and quickly put down the fish that had been killed on the straw mat, and fished for the bucket.

The fishmonger bent down, stretched out his hand, and fished out a fish very deftly.

"How about this one?"

"Well, not bad." Wu Meiniang nodded.

Seeing that Wu Meiniang agreed, the fishmonger passed the hemp rope through the mouth of the fish.

The fish desperately opened its mouth to breathe, and kept flicking its tail.

Wu Meiniang suddenly asked, "You fish, is it alive?"

"???" The fishmonger who had just put on the fish was a little confused, and then despised it.

"It's a fish, and it dies out of water.

Missy, do you think this fish will keep alive? ? "

When the people around heard this, they burst into laughter immediately, looking like they were enjoying the show.

"Well, let me ask you, do you want to keep alive?" Wu Meiniang asked again.

"I think they are here to find fault with sincerity!" the fishmonger asked, frowning.

Seeing more and more people around from the corner of the eye, Wu Meiniang said hastily.

"Don't get me wrong, if your fish doesn't keep alive, put it back.

I want all of your bucket and fish. "

"Oh, then you should have said it earlier."
