The people of Qin are actually very hard.

When you go to war, you either serve as a soldier or as a civilian to provide logistics.

When there is no war, they are ploughing, and when they are not working, there is an endless supply of conscription waiting for them.

There were many, many servitudes in the Qin State, and there was basically no time to be idle.

It's like a large group of people gathering together to talk nonsense and tell jokes or something during the slack season, which does not exist in the Qin State.

Only women can stay at home and take care of their children, and men are either serving or working.

It was at this time that the leaders of the Qian, who were in the regions north of the Wei River, were mobilized to build a reservoir.

Water conservancy facilities were not uncommon for the Qin State, and the famous Dujiangyan, Zhengguo Canal, etc. were built by the Qin State.

They have long known how important water conservancy facilities are to harvesting their fields.

It's just that this time the reservoir is a bit strange, because it is built between the mountains, and there is no large area of farmland nearby that can use so much water except for a small piece of land along the riverbank.

The leaders did not understand why the reservoir was being built in this place, but unfortunately the sergeants who supervised it would not give them a detailed explanation.

At the end of the evening, the leaders of the reservoir would be on their way back to the camp in twos and threes, when they saw the other end of the mountain not far away, bursting with fire and smoke.

At first, I thought it was on fire, but later I learned that there was a huge workshop that would be used as a prisoner.

Judging by the brightness and scope of the fire, the scale of this workshop is really large.

"Taifu, this coke is really easy to use, and the quality of the steel that has been refined recently is very good." A disciple of the Mo family named Helong excitedly reported to Li Yunze, "The steel refined yesterday is more than 100 catties!" ”

"A hundred pounds."

Li Yunze, who was paying attention to the earthen kiln in front of him, nodded, "That's really a lot." ”

In the modern world, 100 catties of steel may only be purchased by those who collect rags, but here in Daqin, it is a rare industrial product.

In this era of the lack of iron products, especially high-quality steel, this is definitely a big step forward in technology.

In addition to pig iron and auxiliary materials, the most important thing in steelmaking is fuel.

Usually charcoal is used, but charcoal is not easy to obtain, and it will seriously affect the ecological environment, turning the clear river into the turbid Yellow River.

In the case of coal, the impurities in it can seriously affect the quality of the steel.

Therefore, Li Yunze provided the technology, and the general was the supervisor to build this coke refining kiln.

Advanced industrial coking plants are not unavailable, but they are really unusable for people in this era.

And this kind of soil method coking, it is much simpler.

First of all, coal preparation, not all kinds of coal can be used for coking, bituminous coal has to be used, and anthracite is most suitable for fuel.

After the coal is selected, it is washed and finally sent to the earth kiln for ignition, which is heated by the combustion of the coal itself, and the impurities are blown out directly through the air flow channel through the exhaust gas and the unburned pyrolytic material (coal ash).

Most of these things are a dark yellow color, like snot, because they contain a lot of sulfur and other impurities.

This process takes about 10 days, and when the coke mature gas is completely burned out, it can be cooled with water and the coking coal can be opened in the kiln.

There is no doubt that this practice will cause serious pollution to the air quality, but for Daqin, no one cares about any air pollution.

What brings tears to the eyes of the Mo family is the power of science and technology!

For Li Yunze, this is something that can be done by just finding a group of Qiantou leaders.

But in the eyes of the children of the Mo family, this is the progress of technology and the take-off of science and technology.

If it weren't for the disappearance of Mozi and the disappearance of the Mo family's tokens, they would even be eager to promote Li Yunze as the Mo family's son.

"That's what it is." Li Yunze's eyes looked at the reservoir on the other side of Shanlong, "When the reservoir is completed, when you see the power of hydraulic punches, you will fall in love with science." ”

The wheels of the times are rolling forward, and the new year has come in a blink of an eye.

Originally, this year, the Qin State was going to attack Han Wei, after all, these two countries have been completely decayed, and it is the Wei State that has declined, after all, the era of Wei Wushu has passed, and Korea has never risen, and it has always been at the bottom.

Unexpectedly, the Qin State did not send troops to Hangu Pass this time, but mobilized troops and horses to turn around and go to the far west.

Meng Wei led 80,000 Qin troops to cross the river westward, sweeping the fertile pastures under the Qilian Mountains.

Along the way, he defeated many tribes of different sizes, plundered their population, cattle, sheep and horses, seized their pastures and land to set up counties, and planted the banner of Qin.

The well-disciplined foot soldiers of the Qin State could defeat the herdsmen of any tribe.

It's just that when these defeated tribal herdsmen fled, the Qin State infantry couldn't catch up.

This was the case in history when Meng Tian fought the Huns.

Although the Huns were defeated, they did not lose much, and most of them managed to escape.

But this time it was different, with Meng Fu on the expedition, there was also a corps of tens of thousands of cavalry with the elite archers trained by Li Yunze as the core.

After the tribal herdsmen were defeated by the foot soldiers, these Qin cavalry would launch a large-scale pursuit.

Where could the herdsmen be the opponents of these well-trained cavalry of the Qin army, armed to the teeth, pursued for tens or even hundreds of miles, and finally escaped without a single herdsman.

Victorious war reports were sent to Xianyang City, which made many generals who failed to get the opportunity to send troops envious.

'If I had to fight, I would have won!' ’

This is really not an incompetent roar under jealousy, in fact, even if you arrange a horse as the main commander, you can win the battle.

At this time, the tribes in the Hexi Corridor were very primitive, and in addition to the arrows sharpened out of animal teeth as arrows, they used simple things such as wooden sticks and sticks as weapons.

And they are nomads, not fishermen and hunters.

On weekdays, it is just grazing, and naturally there is no fishing and hunting people who can exercise their skills, tactics and cooperation through hunting.

The equipment is sparse, there is no organization and cooperation, and I don't know anything about military formations.

Especially in terms of the number of people who are crucial, they are at an absolute disadvantage.

In a war under such conditions, it is still Qin Ruishi, who is the strongest in the world, who commands it, and it is a miracle that he cannot win.

Meng Fu easily swept the Hexi Corridor and captured tens of thousands of horses.

Don't think it's too little, in fact, horses are such a thing, unless they are forced by the tribal nobles, even the herdsmen are not willing to raise them.

Horses are delicate and sensitive, and it is not easy to feed.

But the meat is not as delicious as cattle and sheep, and the leather is not as good as cattle and sheep, so naturally not many people are willing to raise it.

But it doesn't matter, for the poor ghost Qin State in Li Yunze's eyes, it is already a huge gain.

What's more, they also seized more than 100,000 cattle and hundreds of thousands of sheep!

Setting up pastures, raising horses, etc., naturally there are special people to do and arrange, and Qin Guo already has a specific operation process in this regard.

As for Li Yunze, in addition to reading the battle report sent by the copy, he was busy improving the scientific and technological level of the Qin State all day long.

Coke is smelted into large quantities of steel, and special equipment is needed to bend the steel into the desired shape.

After the reservoir was completely built, the crude and primitive machinery was driven by the force of the water flow, and it was finally possible to barely process it.

Steel, machining!

Together, it means industry!

At least in the rudimentary stages of industry.

Beside the stove, Li Yunze, whose skin was reflected in a bronzer, wiped the sweat on his forehead, and pointed to the technicians around him, "Temperature, temperature, temperature!" I said the important thing three times, controlling the temperature is to control the quality! ”

The technicians were resigned, and began to measure with the earth-made thermometer in their hands.

The thermometer can also be made by the local method, the specific method is to fill the bottle with a colored potion, put it in the ice-water mixture until the potion is stable, mark it as zero, and put it in boiling water, and mark it as 100 after stabilization.

As for between zero and one hundred, the standard portrayal will do.

If it is more than 100 degrees, such as the temperature of the earthen kiln, the temperature of the earth-based blast furnace, etc., it is necessary to rely on the rudimentary industrial thermometer and the eyes of the workers to judge the changes in the flame and fire.

It is a newly built glass workshop.

Li Yunze didn't make glass to make money with this thing, but glass has a high application value in industry, and it can also become the best substitute for window paper in civil use.

Just like when Li Yunze mixed black powder, glass was very useful.

"Taifu."

There was an envoy from Xianyang City, who eagerly rushed to Li Yunze's face, "The king has summoned each other, and there are important matters to discuss." ”

Li Yunze, who was shirtless, groped his chin and thoughtfully instructed, "Wait for me to change my clothes." ”

After a lot of effort, Li Yunze, who was neatly dressed, walked out of his room.

He had returned to the modern world to look up the information, and he had a rough idea of what was going on in light of the time.

As for how to deal with it, there are already ways on the way to Xianyang Palace.

Nothing was said all the way to Xianyang Palace.

In the Qilin Palace, Yingzheng, who was full of anxiety, saw Li Yunze walk in, and even got up and went down the steps to greet him, regardless of his identity, "Taifu, you are finally back." ”

"Yes, Taifu is finally back." Over there, Zhao Ji said this in a tone full of resentment.

Li Yunze smiled at Zhao Ji, thinking that he had to find a time to give the Queen Mother a heart booster, because the effect of the last Little Bird Healer had obviously disappeared with the passage of time.

Retracting his gaze, Li Yunze looked at Yingzheng in front of him, "King Beyou, no matter what, there will be a solution." ”

The omnipotent Taifu came back, and Yingzheng, who felt confident, gradually calmed down and told the troubles that Daqin was facing at this time.

The reason is not complicated, but this year's weather has been unfair, resulting in a significant reduction in food production, followed by widespread famine.

In this era of low productivity, food is the most important means of production.

Even if the Qin law is strict, the Qin people who haven't eaten will work hard to survive.

Facing Ying Zheng's expectant gaze, Li Yunze smiled and said, "Don't you forget that Daqin has a lot of food." ”

"Huh?"

"Didn't the Western Expedition seize a large number of cattle and sheep? These cattle and sheep were sold to the nobles of the countries east of Hangu Pass in exchange for their grain for disaster relief. ”
