The craftsmen of the Tang Dynasty moved quickly, but in just half a month's effort, they created hundreds of sets of cavalry three-piece suits.

In fact, it should be said that in this era of imperial power, when something is valued by the emperor, its promotion speed will naturally be very fast.

"Have you tested them all?" Li Er, who was an excellent cavalry general himself, personally inspected these cavalry equipment.

"The Xuanjia Army has tried, and everyone says yes."

As Li Er's real trump card, if there is anything good, it is naturally given to the Xuanjia Army first.

In fact, this cavalry three-piece set is not high-tech, ordinary blacksmiths and cobblers and even carpenters can make it, and the original model of stirrup saddle was available as early as the Han Dynasty. As for the horseshoe, there was a similar nail horseshoe in the former Sui period.

The difference is that what Li Yunze took out is the ultimate model that has been truly optimized, which can be regarded as a perfect product.

"Gather all the craftsmen who are doing this, and remember not to leak them." Li Er knew very well that the production process of these things was not high, and if the Turks were allowed to go, the impact would be too great, "Except for the Xuanjia Army, other departments are not equipped for the time being."

Before the real decisive battle with the Turks, Li Er did not plan to take out these things.

When you're ready to go to war, be sure to impress Jieli, the monster that is said to be able to eat three cows in one meal.

Li Er, who has a conceited and arrogant personality, has never forgotten the humiliation brought to him by the Weishui Alliance.

Be sure to get revenge!

After arranging this matter, Li Er sat behind the book and looked through the official documents.

The autumn harvest has ended, and all counties in Guanzhong have sent official documents, saying that they are very satisfied with the new iron farm tools, especially the iron sickle, which is a large piece of a knife during the autumn harvest, and it is sturdy and durable.

Then the official documents everywhere wrote the same, asking the imperial court to allocate more farm tools, all kinds of things, and they all had to be made of iron.

"Is it all iron that fell from the sky?"

Li Er, who closed the official document, was very helpless, "I also want more iron, but I want to spend gold." The imperial court is in financial difficulties, where did it get so much gold?"

Li Yunze does not accept silk silk, this kind of thing used as hard currency in Datang, he really does not lack it at all.

Although he received copper coins, he did not count them by number, but asked them to be counted by weight after melting.

Because there are too many impurities in the copper coin.

As for silver, it is resolutely not accepted by Datang's official exchange rate, that is, the exchange rate between gold and silver is 1:10.

What Li Yunze can accept is one to one hundred.

Even in the black market of Chang'an City, no one dared to offer such a price.

Because of this, even if he knew that Li Yunze had a lot of good things there, he only hated the lack of financial resources and couldn't do anything.

[In view of the general environment,

Helplessly, he put aside the official document asking for more iron farm tools, and Li Er picked up the next one.

This was sent by Fang Xuanling, and the content was to hire Li Yunze to help clean up the river in Chang'an City.

Since Emperor Wen of Sui Emperor Yang Jian built Chang'an City on the basis of Daxing City, several decades have passed, and the dynasties have changed.

Yang Jian was fine when he was alive, but when Yang Guang took the throne, he didn't deal with the Guanlong Military Group, and he wanted to suppress the gate valve family in Shandong, so he simply ran outside all the year round and didn't stay in Chang'an City at all.

After that, it's a long war.

By the time Li Er ascended to the throne, the river that had not been maintained much for so many years had already been seriously affected by siltation, and it was very easy to breed epidemics.

It's not that the ancients didn't understand that dirty places are prone to disease, they just couldn't see germs.

Li Er also understands this, so he naturally understands that this is a good thing.

Normally, it should be for the people to go out into conscription to do this.

But on the one hand, the lack of the right tools led to this

The difficulty is not small, and another more important aspect is that there have been many disasters in Guanzhong this year, and in order to deal with the disaster, the conscription in various places has already been used.

Forcibly conscripted again, either directly giving money and goods, or damaging the reputation of the court and the emperor and forcibly starting work.

Either way, Li Er is unwilling to do it.

From this point of view, Fang Xuanling's suggestion to let Li Yunze do this is a good proposal.

Moreover, Li Er was keenly aware of the hidden meaning behind this proposal.

Although he still doesn't know Li Yunze's origin, his ghostly ability makes Li Er and Fang Xuanling very sure that this person has great magical powers.

In the face of the existence of such a great supernatural power, of course, he didn't try his best to play slicing, but tried his best to win him over, at least not let him run to the Turks.

There are many ways to win over people, such as Li Yunze, who has great magical powers, and who lacks nothing needs a long and gradual process.

The first thing to do is to recruit them into the city.

Li Er immediately approved and agreed on the paperwork, as for the price or something, it was Fang Xuanling's work to do, and he, Li Er, would not even have to take care of this little thing.

Li Er, who planned to continue working, heard that someone outside asked to see him.

The person who came was the Baiqi Division responsible for protecting Lijiazhuang, of course, it was okay to say that it was surveillance.

"Your Majesty, a group of strongmen broke into Lijiazhuang last night."

Hearing this, Li Er's expression immediately changed slightly, "Who is it?"

What he was most worried about was Li Yunze's collusion with other forces, and in addition to the Turks, there were also those who opposed him.

I also don't want Li Yunze's good things to fall into the hands of others.

The man of the Hundred Horsemen looked a little strange, "It's a cow stealer."

"Huh?"

When Li Er came to Lijiazhuang, he saw a group of people being tied up and escorted to the threshing floor.

There are also many officials from Lantian County on the side, who are talking to Li Yunze about this.

"What's wrong?"

The officials didn't know Li Er, but looking at his pomp and momentum, it was natural for them to give up their positions and not dare to do much.

After all, it is at the feet of the Son of Heaven, who knows which noble family it is, and if he accidentally offends it, he really can't even keep the guy who eats.

"A bunch of thieves." Li Yunze stretched out his hand and gestured to the cowshed in the distance, "Come and steal the cow."

Li Er narrowed his eyes, and his face was very unpleasant.

Cattle are strategic materials in Datang, and any act of stealing cattle is damaging Datang's national strength, so naturally there will be no good feelings for cattle thieves.

"Take them back." Li Er scolded those officials for "severely punish them with the laws of the Tang Dynasty!"

Tang Law punished cattle theft very severely, not only to be punished for theft, but also to compensate according to the price.

This is just stealing cattle, if you kill the cow it will be even worse, directly alongside the felony of plotting rebellion, disobeying parents, minting fake money, robbery with a knife, etc., and it is condemned as a heinous crime.

The cattle thieves were taken away, and Li Yunze and Li Er got out of Zhuangzi and walked to the cowshed.

"Too many cows?"

Looking at the cowshed, which was obviously much larger than before, Li Er was stunned, "There are so many cows, even in Tuyuhun, they have to be a large pasture to feed. Here you are..."

He looked down at the lush alfalfa fields beneath his feet, "Can you feed them?"

"Of course, I have not only the best grass here, but also fodder." Li Yunze walked to the cowshed, "The food is sufficient, the nutrition can keep up, and at most a year and a half to two years old, a two-year-old calf can provide meat."

Li Er's eyelids twitched when he said this: "The sturdy bull doesn't go to plough the fields, but eats meat... It's a."

"If you think it's a waste of money, you can buy it." Li Yunze smiled and waved his hand, "Don't worry, it's definitely cheaper than Tuyuhun's cow." I don't care if I cultivate the land or eat the meat after I buy it."

"Huh?"

Entering the cowshed, Li Er, who endured the unpleasant smell, looked at the white cows suspiciously.

What kind of cow is this?"

"Cows."

Li Yunze said seriously: "Sun Daochang is the cow used to take cowpox."

Hearing this, Li Er nodded abruptly, "It turns out that you raised these strange cows to get rid of cowpox."

Li Yunze looked at Li Er's gaze as if he was looking at Sha Wither, "Are you crazy?" Cows, of course, are used to get milk."

"Milk?"

"Milk is a high nutrient, and drinking milk makes you stronger. It also makes cheese, which is a high-energy food that can be stored for a long time, especially for long journeys of troops as military rations."

Hearing that he could make military rations, Li Er immediately stopped sleepy, "Okay, very good. How much can it produce?"

"During the high-yield period, 50 pounds a day. In the low production period, there are always ten pounds a day." Li Yunze explained, "If you make cheese, ten catties of milk can produce one catty of cheese. When marching and fighting, a pound of cheese is enough for a sergeant to consume for a day."

Li Er, who looked extremely serious, turned to stare at Li Yunze, "I will give you all the land nearby, how much cheese can I provide during the autumn harvest next year?"

He has already made up his mind that after the autumn harvest next year, he will send troops to fight against the Turks, and he must destroy this monster that threatens the Tang Dynasty all the time.

For anything that will increase the combat effectiveness of the army, he will not refuse.

Li Yunze smiled, "Your Majesty, is this going to sign a supply and marketing agreement?"

「... What agreement?"

"The supply and marketing agreement, that is, you buy all the goods I shipped."

"Yes!"

As the days passed, the weather gradually cooled down.

Winter is coming, and it is not surprising that snowflakes are falling in the sky.

It's snowing.

Snowflakes fell from the sky one after another, some of them melted into droplets of water and soaked the earth not long after they fell to the ground, and some of them fell on the cold grass blades or branches that had long been frozen by the cold wind, gradually accumulating a layer of ice and snow white.

The longer the snow falls, the whiter it gets. The black road becomes clearer and clearer in this white world.

This road is the cinder road to Chang'an City built by Li Yunze from Lijiazhuang after the autumn harvest.

There are also coal mines near Chang'an City, and Li Yunze purchased the coal produced by the coal mines on a large scale, and even forced the coal mines to increase their output frantically, and almost the entire prisoners in Chang'an City were sent to the coal mines to dig coal.

The cattle thieves who stole cattle in Lijiazhuang before were also sent over.

At the beginning, Li Er didn't know what Li Yunze wanted so much coal for, but as a rare cargo that could be exported to Li Yunze, not the Lanting Collection or a beautiful woman or something, he still strongly supported it.

Fang Xuanling offered a price that was definitely high in his opinion, but Li Yunze didn't even pay it back, and directly responded to it.

He felt at a loss at the time.

When Li Yunze made the coal into honeycomb coal and sold it with the stove in Chang'an City, and then used the remaining cinders as road building materials, Fang Xuanling's heart hurt even more.

Li Yunze made more money selling honeycomb coal than Fang Xuanling made from selling coal.

Sure enough, this female businesswoman!
