After everyone visited the crushed area in the stockade, they went to the quarry area at the top of the hill to visit.

In the face of how to efficiently take ore, everyone is also very curious.

After all, judging from the trolleys queuing here, the amount of ore produced by this stockade every day is definitely not low.

If you only use people to beat and quarry, the yield will definitely not be high.

After getting the quarrying area, Li Yi understood most of the principles at a glance.

Since this cottage is an open-pit mining method, the method of mining by the craftsmen is clear at a glance.

In between, the craftsmen now dug out a ravine under the mountain wall, and stuffed the ravine with something black.

Then they set the black ones on fire, and the black things burned straight away, and the black stone things burned very violently.

At the same time, the craftsmen on the side also used a bellows to blow the air of these burning black things.

As the wind blew, the black thing burned even more violently.

The yellow-white flames quickly licked the stone wall above, and at the same time, the top of the originally cyan stone wall was also scorched black by the smoke.

As the flames continued to burn, some craftsmen continued to throw new black objects into the ravine to keep the flames warm.

Soon the stone wall made a "click, click" sound under the calcination of the fire, and some of the broken stones even fell directly.

But the craftsmen kept adding black things to keep the flame at a certain height.

As the temperature continues to rise, the clicking sound of the stone wall becomes more and more intensive.

When it seemed that it was almost done, suddenly several craftsmen carried a huge bucket and stuffed a pipe sewn from an unknown animal skin into the barrel.

Then a craftsman brought a bellows-like object over and attached it to the pipe.

As the bellows-like thing kept pulling, the water in the bucket was quickly pumped into the leather pipe.

Then the craftsman pointed a section of the leather pipe at the stone wall, and the water in the pipe was quickly sprayed onto the hot stone wall.

As the water cooled down rapidly, the original clicking sound of the stone wall became louder and denser, until it finally became a continuous "click" sound.

Then there was a "boom", and a large area of the stone wall fell off from the mountain, and the fallen stone wall was broken into pieces.

"What is it about all this black stuff that can burn?"

Hae-in picked up a black object scattered on the ground and pinched it in his hand, and then the thing shattered in his hand.

"This thing should be called nirvana, or peat, because it is said to be like a stone but can burn, like nirvana, so it is called nirvana, and because it is so similar to charcoal, it is also called peat."

This time, it was Jing Zizheng who solved Haiyin's confusion.

For these things, he had studied them in Guigu Mountain.

"Since there is still such a thing in the world, if my grassland tribe has such a thing, why would so many clansmen freeze to death during the White Plague!"

Saying that, Hai Yin's face showed a sad look.

"I have to say that you Dayu is still rich in products, and you Dayu have all these treasures."

"Hey, Haijun, you are wrong, according to my master, the place with the most Nirvana is not in the territory of my Dayu, but in your grassland, but it is a pity that you live in Baoshan and do not know it."

Keiko said with a smile and patted Hae-yin's shoulder.

As soon as these words came out, Hai Yin and Yu Zhenlei were all stunned.

After a long pause, Hai Yin asked Li Yi eagerly.

"Childe, is this true?"

The reason why Hae-yin wanted to ask Li Yi instead of Jing Zizheng was that he was worried that Jing Zizheng was joking with him.

"The master did say that the place with the most Nirvana stones is indeed your grassland area, and he also said that the Nirvana stones there are only one or two meters above the ground, and it is very convenient to run away from the soil on them and mine them directly."

Li Yi nodded and said.

As soon as these words came out, Hai Yin's tears remained, and then his body began to tremble uncontrollably.

Then he slowly crouched down, hugged his head, and began to cry.

And Yu Zhenlei on the side also kept pulling his hair with a chagrined expression.

The people around them all looked at the two of them with strange eyes, and they didn't understand why these two people behaved like this after hearing that there were a large number of nirvana stones on the grassland.

The joys and sorrows of human beings are not the same, which is what the Taoist sages said: Zifei fish knows the joy of fish.

Similarly, Li Yi and the others were not Hai Yin and Yu Zhenlei, so they couldn't understand their mood at this time.

You must know that in fact, the biggest enemy of the grassland tribe is not the Dayu Dynasty over there, in their opinion, the Dayu Dynasty is just a neighbor for them to plunder.

Even when Emperor Shengwu was alive, the Great Yu Dynasty could only be regarded as a powerful opponent at best, and it could not be called the biggest enemy.

In fact, the biggest enemy of the steppe tribe is the annual white plague.

Every year, a white plague causes a large number of herders and herds to freeze to death, and in extreme cases, a single white plague can wipe out a smaller tribe directly.

And even if he Xianbei tribe is one of the eight major tribes, there are a lot of people and livestock who are frozen to death in the white plague every year.

Therefore, in order to ensure that the tribesmen can survive the white plague, the grassland tribe will launch an attack on Dayu every autumn every year.

Every grain of grain that the steppe soldiers who participated in the grass valley snatched back meant that the tribesmen were more likely to survive the white plague.

Therefore, in a way, instigating the grassland tribe to attack the Dayu Dynasty every year is not a wolf court, but a white plague.

And during Haiyin's reign, he couldn't count how old the lives of the Xianbei people had been taken by the White Plague.

Those who were taken away by the White Plague were his people, his people!

As for Yu Zhenlei, he hated the White Plague even more, because his mother, the poor woman, was frozen to death in the White Plague because the tent collapsed due to the heavy snow.

And if he had this nirvana stone, he could have lit a fire in his mother's tent, so that the snow on the tent would not have been so thick, and his mother would not have been crushed under the tent and frozen to death.

So now the two of them are in a state of chagrin.

"Haijun, Yu Zhenlei, you don't know that there is a nirvana stone in the grassland, so why blame yourself! It's not your fault. ”

Li Yi looked at their expressions and guessed the reason for the grief of the two, because his master had said that the grassland tribes were constantly plundering the Dayu Dynasty in order to survive, and every year a large number of people and livestock from the grassland tribe would freeze to death.

Li Yi gently patted the shoulders of the two of them.

"Don't take the blame for non-existent faults."

With Li Yi's relief, Hai Yin and Yu Zhenlei finally stopped crying, but this kind of grief is not something that can be relieved for a while.

They then went on to visit other parts of the cottage that were also using traps on a large scale.

As it got dark, everyone lived in a few simple wooden houses under the arrangement of the cottage steward.

Sitting in the wooden house, roasting Nirvana on the stove, everyone was roasting food while discussing the mechanism they had just seen.

"What I saw and heard in this cottage today is simply incredible!"

Qi Chaojiang said while nibbling on a piece of bread.

"Yes, the little one has been wandering in the city of Luozhou for so many years, and I have seen a lot of merchants from the south to the north, and the goods they bring from all over the world are also considered to be thousands of strange, and compared with the institutions and things seen in this cottage, I always feel that those things are not worth mentioning."

Hu Qing said with emotion.

Although everyone felt that what this guy said was a bit too big, they also had to admit that this Hu Qing had indeed seen more rare things than them.

After all, he has been in the city of Luozhou for many years, and because he is good at picking locks and taking sweat medicine, he has not been less than stealing those merchants who have rare things.

"That's right, not to mention those big guys, just the wheel that Childe said is extremely magical, and it can make things lighter, isn't this a fairy spell!"

Xu Yan felt that he had really opened his eyes today.

"Boss Xu, Childe said it's a pulley set!"

Zhang Zhou next to him reminded in a low voice.

"You kid has a good memory!"

Xu Yan immediately slapped Zhang Zhou's head next to him.

"Li Yili said, since the organs of Anzhou are so magical and so easy to use, why does the Dayu Dynasty not allow these organs to flow out of Anzhou?"

Qi Chao didn't understand the truth of this.

"That's right, if these things were popularized throughout the Dayu Dynasty, wouldn't they be able to completely benefit the people? This is clearly a good thing for the benefit of the country and the people! ”

Qi Ning also expressed dissatisfaction with this ban of the Dayu Dynasty.

"It's not just you who don't understand, but even the people of Anzhou don't understand."

Yang Ping said as he flicked the nirvana stone in the furnace with a branch.

"You must know that whether outsiders enter Anzhou and then go out, or the people of Anzhou go out of Anzhou, they need to go through a strict check, and once someone is found to be carrying Anzhou's organs, the government will impose heavy fines."

"I didn't expect this kind of thing, no wonder I haven't seen these objects in the Dayu Dynasty for many years!"

Although An Su is a person with the surname Zhaowu Jiu, he has lived in the Dayu Dynasty for a long time.

"Even if the Dayu Dynasty does not allow the logistics of Anzhou's organs to be transmitted, this kind of good thing that benefits the country and the people is not imitated by people in other states?"

Qi Ning asked incomprehensibly, in her opinion, no matter which of these artifacts they were, they could save a lot of manpower, and for people in other places, they should be rare treasures.

If the Dayu Dynasty did not allow the outflow of Anzhou's institutions, then the vassal kings and Jiedu envoys, who were the masters of a land, should be interested in these institutions.

In other words, she is a vassal king or jiedu of a place, so she will definitely do everything possible to get these tricks into her fiefdom, so that she can use these traps to develop the fief more strongly.

Everyone nodded after hearing this, and they also felt that Qi Ning's question was very reasonable.

In this regard, only Li Yi, Jing Zizheng and Hai Yin were present, but they laughed and did not speak.

Qi Ning saw that the smile on Li Yi's face was more or less contemptuous, and she couldn't help but look at Li Yi angrily.

Li Yi couldn't help but shrink his neck when he saw Qi Ning's eyes, and then he opened his mouth to explain.

"Actually, what you said is right, the vassal kings and jiedu envoys of the states really don't want these institutions to be introduced into their fiefdoms."

Li Yi's answer made Qi Ning and the others even more confused.

"Such good things for the benefit of the country and the people, why do those vassal kings and festival envoys oppose it?"

Qi Chao felt that Li Yi's statement was completely unreasonable.

"That's because when you look at this issue, you are standing from the perspective of the people and the people, not those vassal kings and festival envoys."

Jingzi Zheng saw that everyone didn't understand what Li Yi meant, so he opened his mouth to explain.

"Does it make any difference? Isn't it all for the fiefdom? ”

The Qi Dynasty still did not give up, and wanted to get to the bottom of it.

"Actually, this involves the so-called imperial art, to explain this issue, I think Haijun may have more say."

As he spoke, everyone's eyes turned to Hai Yin's body.

Seeing that everyone's eyes were focused on him, Hai Yin smiled faintly, he enjoyed this feeling of being noticed very much, he had been very intoxicated by this feeling when he was in the clan before.

And now, although there are not many people who pay attention to him, it can still make him feel an inexplicable pleasure.

"On this issue, I remember that there is a saying in your Dayu Dynasty called: The Art of the Emperor."

As Hai Yin said these four words, everyone was stunned, in their cognition, the art of the emperor can only be learned by emperors and generals, but they can't learn it.

"What do you think are the things that you are talking about about the most important things of the vassal kings and the envoys of the festival?"

Hae Yin saw that everyone was a little confused, so he continued to ask.

"It's money."

"No, it's supposed to be power."

"I think that if I am a festival envoy or a vassal king, what I care about most is to have a lot of women."

"Look at your appearance, I think those guys care most about their own lives."

“······”

Everyone, you and I have said your own answers.

"These are the things you want, not the things that the vassal kings and the envoys want."

Hai Yin shook his head with a smile and said.

"The things you are talking about are all things that are readily available to those vassal kings and festival envoys, and they already have them."

"Haijun, don't sell Guanzi!"

Qi Ning was whetted by Hai Yin's question.

"Actually, what those vassal kings and jiedu envoys care about the most is not what you say, they only care about two words the most: stability."

"Smooth?"

Everyone was very incomprehensible to Hai Yin's answer, and in their opinion, stability was nothing compared to what they were talking about.

"That's right, in fact, in the eyes of those vassal kings and festival envoys, it doesn't matter if the people of their territory are doing well, whether it is difficult or difficult, as long as it is stable, he can enjoy everything he has with peace of mind."

Everyone was carefully reminisced by Hai Yin's words.

"And once these organs are introduced to other states, it will inevitably cause great changes to the states, these organs will replace people's work, and will also reduce the price of goods, so that those who rely on selling their strength will inevitably not survive, and these people who can't survive will break the original stable situation, which is why the Dayu Dynasty and other states do not imitate the institutions, because they will break the foundation of those who are in power to survive."

After Hai Yin finished speaking, although everyone felt that what he said was very reasonable, they still couldn't accept this so-called imperial mental technique.
