Lu Hanyang just happened to meet this caravan, and saw the caravan owner and the thin man's eye contact. Only then did he try it, but it turned out to be a hidden drawback.

Datang's cement has now become a very sought-after thing, which can be said to be close to the point of strategic materials. Because this is a new thing, and the Datang road and city wall are big consumers.

So the firing process has become a bottleneck that limits cement production, why? Because of the lack of manpower, crushing limestone is a very intensive labor, and it needs to be crushed to be able to burn qualified cement.

This requires a lot of labor, after all, without a crusher, how much can a strong laborer crush in a day?

It's not just crushing, it's also digging coal. Choose between burning charcoal and charcoal, which is much less expensive than charcoal and is more durable to burn.

As a result, coal has become a new industry, and families and nobles are looking for coal mines all over the world. The shallower coal from the surface of the earth was found by them, and in that area of Shanxi, the Taiyuan Wang family made a lot of money.

Because they are sitting on top of the coal mines, they are completely close to the water and get the moon first. At this time, they received much greater benefits than other families.

Just digging coal also requires a lot of manpower, and because it is a new industry, digging without experience causes a lot of damage to their labor force. After all, it is digging deep underground, and safety is not guaranteed at all.

Because of the landslide, many people have been buried alive. Therefore, the Taiyuan Wang clan did not dare to let the people enter the mine anymore, so they set their sights on the slaves.

So the family took the lead, your cement kiln needs manpower, my coal mine also needs manpower, the price of hiring people is too high, and there are too many dangers, so use slaves!

After hitting it off with each other, Datang's slave catching team appeared.

Whether it was a prisoner of war on the battlefield or something else, it was all in demand at this time. As long as they were slaves, they were put into the mines, into the crushers, and in the cement kilns, unloaded, and so on.

These were labors that were too expensive to hire, and they were all replaced by slaves.

Countless slave catchers disguised as caravans searched everywhere for those who would not attract attention even if they disappeared, and they did not dare to be too presumptuous, after all, they were in the country and the population was small. The imperial court is worried about this, so it can only be sneaky.

Of course, there are also conditions that are good enough, and more people can be sent to form a more professional team to infiltrate the surrounding alien races. As a result, there are many more guys from other nationalities in the slave ranks of these big families.

For example, the Goguryeo, Silla, and Murowei people in the east; The Tubo people in the west, the Tuyuhun people, and the people with the surname Zhaowu Jiu, and even Gaochang, Tocharo, and the Western Turks are not without them.

Under the lure of interests, the power of these families and noble families is very large, and these people are secretly taken captive, perhaps tempted by interests, or directly tied by force.

In short, after arriving here, they are slaves, two-legged livestock that contribute to the cause of Datang cement.

However, all the people who can go abroad to carry out such a big move are the top big families, and those small and medium-sized families do not have such power. So they can only make a small fuss in the country, and in general, these two teenagers are such goods.

It's just that Lu Hanyang didn't expect that there would be such a soft bone among these two teenagers, and it can even be said that he is an undisciplined person. In this era, it was the first time he had seen such a brazen person, so much so that he borrowed Zhuge Liang's famous words.

In the past few years of "Immortal ......", Lu Hanyang's reputation has been thunderous throughout the Tang Dynasty, his image has also been widely praised, and the information of riding a huge crane has long been known to the world.

These people below all saw Lu Hanyang riding on the back of the crane in the sky, and suddenly everyone's faces turned pale: they didn't know what kind of temper this immortal would have, but they definitely didn't think that he would let go of these people.

"Immortal Chief...... Immortal Chief, spare your life! We're just doing what we're told, Immortal! The rich middle-aged man, that is, Zhang Mazi, knelt on the ground at this time, kowtowing like pounding garlic.

"Whether you are acting on orders or not, this seat will discern by itself, and now this seat wants to clean up this traitor and glory guy first, you get out of the way and stay aside." Lu Hanyang ignored him, he was even more interested in the young man who sold his friend.

"Immortal Chief, I didn't mean to, I just want to live!" The betrayed boy cried, how did he know that suddenly this famous immortal of the Tang Dynasty actually appeared here.

"Really? If you want to live, doesn't he want to live? You can be regarded as in the same boat along the way, why did you not hesitate to betray him so much? Lu Hanyang wanted to see what this young man would say.

"Because he is a side branch of the Xue clan in Hedong, I hate these families, I have hated them since I was a child, if I hadn't been able to beat him, I would have done it myself!" The boy said.

"Hate the family? It's funny, but dressed like this, how can it be a big family? Lu Hanyang asked the young man named Xue Li.

"Qiyu Immortal Chief, my ancestor is indeed a side branch of the Xue clan in Hedong, but he has long been defeated, I don't know why Wang Duan resents me." Xue Li replied.

"Why? Don't you know, you look at the destruction of the village, do you know why it was destroyed? It is because the Taiyuan Wang family has taken a fancy to the coal under our village. You families are like this, you don't care about the life or death of our people! Wang Duan said.

"The Wang family actually destroyed a village for a carboniferous mine?" Lu Hanyang's face was slightly stunned. He didn't expect that the first accumulation of capital would be so bloody.

Of course, as long as there is a place with coal, the Wang family would like to occupy it all, and he also arrested many people to mine, and even died without knowing when he died. Wang Duan, the young man, said a terrifying sentence from his mouth.

"It seems that this seat is still too kind to these family families, there is a reason for you to hate the family family, but this Xue Li has not done anything evil, why do you hate him too?" Lu Hanyang wants to find out the reason.

"Because he is going to defect to the Xue clan in Hedong this time, Xue Wanche is now in Luoyang, he will soon be a member of the family, and he will also be the one who oppresses the people in the future!" Wang Duan said that his logic is very peculiar, either good or bad.

"Okay, your answer makes me not think you're wrong, you can go......" Lu Hanyang decided to let this Wang Duan go.

"Immortal Chief, are you really letting me go?" Wang Duan couldn't believe it. <
