However, what Kuntu didn't expect was that the Han Dynasty's methods were actually far more than these.

Just visiting a place around Luoyang?

It's too inferior.

Just when Kuntu was hoping that his sister would be close to Wang Buxu, the Ministry of Rites had already begun to summon these envoys from the Western Regions to visit the eastern industrial zone in person.

Let them truly see what is truly powerful.

And Quintu never expected that his sister was still receiving training.

It is not easy for a Han woman to become a member of the emperor's harem. She needs to undergo various etiquette trainings and so on.

Not to mention Princess Wusun.

The first item is the language issue. The female officials in the palace need to correct Princess Wusun's thick Luoyang accent.

It's not that you can't have an accent, but the accent shouldn't be too strong. When you talk to the emperor, you can't just say something when you open your mouth. You'll kill me in vain...

Although it can be used sometimes, the things Lu Jia taught them for fun must be corrected.

Then Princess Wusun also had to learn the etiquette knowledge of the Han Dynasty, what kind of etiquette should be performed when meeting people, what level of people do you salute when you meet, how should you respond, and how to judge a person's official level by appearance.

Although the harem does not have many opportunities to contact outside officials, there are no absolutes in everything.

Therefore, for a while, Princess Wusun had no chance to sleep with the emperor.

Besides, it is no longer the time when ministers were following behind every day to urge Wang Buxu to marry a wife and have children.

Now the Han Dynasty has three princes and three princesses, and the emperor is still young and can still have children. In fact, there are already people for the successor. It is just a question of whether they are suitable or not.

But whether it’s appropriate or not, I can’t tell now. How can a three or four year old kid tell that?

Quinto is also on the inspection list.

I have to say that the size of the mission is quite large.

However, because they were in the territory of the Han Dynasty, their guards were left in Luoyang, and the ones responsible for protection were the Forbidden Army.

The vehicles formed a long queue, which looked very lively.

The roadside is full of crops that have just sprouted, as well as calf-high wheat, a lush green area.

There are newly built water canals everywhere in the fields.

"Envoy Lu, are these things used for irrigation?" An envoy from the Western Regions pointed to the canals in the fields and asked with confusion on his face.

They had never seen this thing before, and it was winter when they came here last year, so they didn't see these things.

"Oh, that's what you're talking about? Yes, it's the tool we use for irrigation." Lu Jia looked at the ditch, and a burst of pride appeared on his face.

That's right, we Han people don't have any other abilities, except that we have a great spirit of hard work.

"We have too much arable land. Although the water source is relatively abundant, it is difficult to irrigate all of it. However, if we do not try to find a way, the crops will be short of water and reduce production. But if we irrigate all of it, it will be difficult to irrigate all the land."

There will be a shortage of water.”

"In order to solve this problem, we designed this tool. The water can flow from the riverside to here, and then continue to flow to places dozens of miles away."

"Although the water flow is not large, the efficiency has more than doubled compared to the previous irrigation, and it can also ensure that all cultivated land has water available."

Lu Jia only found out about this incident when he was wandering around the court recently.

Similarly, because these devices are made of bamboo and cannot withstand long-term wind and rain, in order to ensure their service life to the maximum extent.

So this thing is put up every year during the watering time. Of course, the country cannot have so much energy to do such a thing.

Whoever owns the land is responsible for it. The materials are provided by the court, and the individual is responsible for erection, dismantling, storage and protection.

Those that have been used for several years or are damaged can be replaced, while those that have been eliminated are recycled and used for paper making.

Anyway, for papermaking, the new ones and the old ones are the same, there is not much difference.

Soon, the delegation arrived at the first stop of their trip, the mine.

What is there to see in the mine?

In fact, there is really a lot worth visiting at the mine.

Although it seems to be just a simple manual job, it also contains huge technology and wisdom.

At first, many people thought they didn't take it seriously, but when they got closer to the mine, their eyes widened.

Wherever you look, there are vehicles filled with iron blocks everywhere, and people are queuing up and don't know where to go.

Farther away, thick smoke was rising in the sky.

Environmental protection, you say?

Well, there is actually no such concept these days, and even if there is such a concept, the technology is not available.

In the face of hard power, these are actually secondary. If human beings want to develop, they must give up some things.

How to make weapons without smelting iron?

If you don't build weapons, how can you build an army?

How to resist the Huns without an army?

Therefore, the inevitable result of paying attention to environmental protection now is to wait for the Huns to invade.

The iron smelting plant is a secret, and many things cannot be seen in person, such as the entire iron smelting process, the order and dosage of adding materials.

But when these envoys from the Western Regions saw the red molten iron being poured out and then entering the grinding tool to form the iron blocks they had seen before, each one of them couldn't help but exclaimed loudly.

If they hadn't seen it with their own eyes, who would have believed that the big man had actually reached this point?

This kind of smelting efficiency is really too high.

"Envoy Lu, will those iron blocks be directly turned into weapons?" Kuntu swallowed secretly.

Seeing so much iron and such a magical method of smelting iron, he was a little scared.

No wonder even the farm tools of the Han people are made of iron, but they cannot even make all-iron weapons and equipment. This kind of production capacity is far beyond what they can compete with.

"Well, haven't you seen the general steps?" Lu Jia continued to nod with an incomprehensible look.

Of course what they saw was not the final result.

They were not even allowed to see the hydraulic forging machine shop. What these people saw was a forging machine built manually and powered by animal power.

Similar to grinding, a special device is used to allow the rammer to fall along the track when it reaches a certain height.

The efficiency is a bit slower than the hydraulic forging machine, but it is also much faster than the previous one.

Moreover, the current hydraulic forging machine has been upgraded.

In the past, it was necessary to lift the tamping hammer to a high place and drop it, relying on its own weight and the force of the fall to ram it.

But now there is no need to lift it so high. Basically, it is enough to lift it as high as an arm, which once again improves the forging efficiency.

At the beginning, the forging machine could only complete the preliminary processing, and people still needed to hammer and forge the final steps.

But it is no longer needed now, the pipeline model has been thoroughly studied.

A team is equipped with three different forging machines. The first one makes rough blanks and shapes them.

The second type is used for subsequent fine processing to shape it into the specific shape of the weapon and the required thickness.

The third type is used for final finishing, and then the same hydraulic grinding machine is used for edge processing, followed by tempering and forging to improve quality.

What the mission saw was specially designed for them to visit. Compared with the forging machine workshop, the efficiency was more than twice as low, and it was still in an early stage.

But even this frightened them quite a bit.

As for those iron blocks, they are just for convenience of transportation.

Here, rough processing is also carried out, iron is refined, and waste residue is left. After arriving at the place, secondary smelting is performed to improve the quality of the iron and forge it into steel, and then the iron blocks they saw in the weapons workshop, or

Said it was a steel ingot.

After a quick tour, everyone started going up the mountain.

There is a smelter at the foot of the mountain, and a mine on the mountain.

And a cable car was actually set up between the mine and the smelter.

The cable car is very simple, but the effect is very good. The mined iron ore is directly put into the hanging basket, and then the hanging basket is hung on the hook reserved above. The livestock at both ends rotate, and the upper and lower layout is used.

Transport the ore from the mountain to the smelting plant below the mountain.

The advantage of this is that it greatly saves the time and efficiency of ore transportation, and more people can be used for mining.

"It's so shocking..."

"Yes, there are almost thousands of people here..."

"I think there are almost tens of thousands of them. Some are mining, some are crushing large ores, and some are transporting."

"Do you know where the scariest place is?"

"???"

"Look at what they have in their hands..."
