There are many fruits and pastries on the stone table, each of which is full of energy and delicious, and it is a rare item.

"Come, Yang'er Kong'er, try the bean curd cake that my mother just made, I remember when I was a child, you loved to eat this thing. ”

"Thank you, mother!"

Yeyang took the green pastry handed by Han Qinglan, picked up a piece with a smile and bit it, the bean cake melted in the mouth, a wisp of aroma wafted in the mouth, and the aftertaste was endless.

More than a dozen bean cakes, three pink blood peaches, two fiery red vermilion fruits, and drank a large bowl of green pulp, Yeyang touched his swollen belly, and said with a smile to Han Qinglan: "Mother, the child is full, and I have to go to the mine with Grandpa Li to check, you eat slowly, I will leave first." ”

As he spoke, he saluted and walked away, and the night sky also wanted to catch up: "Brother, wait for me, I want to go and see it too!"

"You kid should be honest and cultivate at home! The next time I go to the Yuelan Grassland, I'll take you with me." Yeyang smiled and shook his head and left, leaving a little emotional night sky.

"Look at your brother, I'm busy all day, and I don't know what your father thinks, hey!" Han Qinglan pulled the night sky, sighed, and said distressedly.

"Sister, don't worry, Yeyang is about to grow up, it's good to have more experience. Han Yun comforted her.

......

In front of the gate of the Night Mansion, Yeyang and Li Mingchang converged here, leading the two elders of the Earth Demon Kingdom and more than 20 soldiers, and they took a huge flying boat and headed towards the vast domain hundreds of thousands of miles away.

Cangmang Domain is located in the center of the Earth Demon Country, which is the largest area among the various domains of the Earth Demon Country, and it is also the former capital of the country, which is the economic lifeline of the country, and the only large mineral vein is located here.

A huge mountain range of tens of thousands of miles is located, and from a distance, it seems that there is an auspicious light spraying thin, colorful, and as soon as it is approached, there is a strong vitality rushing to the face, making people only feel like a spring breeze, boundless pleasure.

Everyone took a twelve-winged flying boat, this kind of flying boat is expensive, even the earth demon country has only three, Yeyang has become the order division, and it is necessary to run back and forth between places, so one is naturally allocated.

The Cangmang Domain and the Night Silence Mountain Range live next to each other, and the distance between the two is only a few hundred thousand miles, and at the terrifying speed of the twelve-winged flying boat for thousands of miles a day, in less than two months, they came to the Earth Demon Mine Mountain Range.

Outside the Mine Mountains, a group of people were waiting here neatly, and after a while, a flying boat broke through the air and landed on the ground, and a group of people walked down from the flying boat, led by a teenager and an old man.

"I've seen Your Highness, Li Xiang. A group of people fell to their knees and said in unison.

Li Mingchang glanced at it, and Yeyang immediately stepped forward: "You're welcome, please get up." ”

"Thank you, Your Highness!" said the crowd, and then got up.

An elder stepped forward and hugged his fist at Yeyang and said, "I heard that His Royal Highness and Li Xiang are coming to check on the mine, and the old man has already prepared a banquet to catch the wind and wash the dust, please two of you here." ”

In the greeting team, a dissatisfied whispered to the people around him: "A hairy boy, I didn't see him come back when he was in danger, and now the situation is gradually stabilizing, he ran back to show off his might, and actually let us pick him up, what kind of thing is he!"

Although the voice was small, it couldn't hide it from everyone, and the leading elder scolded: "Shut up!" and hugged his fist apologetically to Yeyang: "Your Highness, forgive me, the people under my command have no knowledge, please don't take it to heart, the old man will definitely punish him severely." ”

"That's it, an unintentional mistake!" Yeyang smiled and shook his head, he had just come back now, but he had taken over such an important task, it was reasonable for someone to object, and he didn't need to worry about anything for this kind of thing.

The group continued to move forward, entered the huge mountain range, followed a mountain road, and headed towards the mine, where a forbidden air formation was set up to block the road into the mountain, and it was impossible to fly, which was also to prevent thieves from sneaking in.

There are some brute beasts of three or four grades along the way, but there is no danger, the high-level brute beasts are either cleared and killed by the army, or they are expelled into a certain area, and there is a strong formation to block it, and it is difficult to get out.

The mine is located at the foot of a large mountain, where many tents and houses are built, and large and small caves have been excavated on the mountain, and many people come and go, mining all kinds of ores.

Pieces of ore of different sizes were packed in carts, pushed out of the cave by some shirtless men, and transported to a stone castle at the foot of the mountain, where the ore containing demonic energy and vitality would be cut into regular crystals, which were the demonic crystals used by cultivators.

The people who mine here are either criminals who have committed serious crimes but cannot be killed for some reason, or convicts who come to serve, and in some special periods, when the army is idle and the mines are understaffed, soldiers will be arranged to come here to sharpen.

"Your Highness, the old man has prepared refreshments, do you need to go in and rest. Through conversations along the way, Yeyang also learned the origin of this Earth Demon Elder, who was from the Stone Monkey Clan and named Sun Qian.

Yeyang shook his head: "No, let's go to the mine first!"

"It's okay, Your Highness, please come with me. Sun Qian clenched his fists and led everyone into one of the mines.

The passage was narrow, diagonally downward, and as it gradually deepened, it widened, and a vast cave appeared, and shirtless men were digging in the cave walls with shovels, and the soil layer was peeling off, and huge mineral sources appeared.

In the veins of the minerals, most of them are demon crystals, a small part of them are yuan crystals, in addition, there are also attribute crystals within cold crystals and fire crystals, and in rare cases, it is possible to dig a series of heavenly and earthly treasures associated with the crystals.

Seeing Yeyang and the others enter the cave, these people who were mining stopped what they were doing and knelt on the ground one after another: "The little one has seen the adult." ”

"Let's just take a look around. Yeyang waved his hand back, and these people dispersed and continued to do their work.

An iron pickaxe was placed on the corner of the cave, Yeyang curiously picked up a hand, held it in his hand and waved it, the iron pickaxe was heavy in his hand, Mo was about more than 10,000 catties, it was made of the best mortal iron, although it was not a treasure, but it was also sharp and abnormal, but digging on these hard mountain walls, it could only go about half a foot deep, which seemed to be a little insufficient.

"Is this what mining is for? This thing is too sharp, why not replace it with a treasure weapon?" Yeyang pouted and put the iron pickaxe back in its place.

Hearing this, many people in the crowd showed disdain, and Sun Qian also arched his hand embarrassedly: "Your Highness laughed, there are 100,000 iron pickaxes like this used in the mine, if they are all replaced with treasures, it will be a lot of expenses, and now it is still a period of war, and even the armaments and weapons are still insufficient, how can there be extra manpower to cast them?"

"Yes. Ye Yang didn't say anything, but looked at the topless and numb ore digging, and asked, "Who are these people?"

"Most of them are prisoners who have committed some minor crimes, and they will be released after the end of their service here, and a small number of people who have committed serious crimes, but for some reason they can't kill or release them, so they have to keep digging here. ”

Sun Qian explained, and then Yeyang asked many more questions, and Sun Qian answered them one by one, and they came out of the mine and entered the kind of fortress made of huge stones.

There are also many people working in the stone castle, different from the mine cave, the number of people here is relatively small, but the cultivation is quite shallow, these people are full of energy, with special royal weapons to use special royal weapons to cut large and small demon mines, difficult to cut into pieces of demon crystals, transported into the warehouse.

The texture of the demon crystal ore is very hard, and it is not much better than the best mysterious weapons, it is extremely difficult to cut, and the speed is also very slow, and many people are sweating profusely.

Sun Gan brought everyone into the warehouse where the ore was collected, and a glittering hill was piled up in front of him, and he pointed and said: "Your Highness, these are this year's mining harvest, there are 69 million demon crystals, 32 million yuan crystals, and the other crystals add up to a total of 4.6 million, do you need to clean it up?"

"So many, how many laborers do you have here?" Yeyang didn't answer, but asked again.

Sun Qian thought for a moment and replied, "With the overseer, there are about 10,000 people, what's the matter?

"That's how it goes, and the average amount of mined is about 10,000 per person per year. Yeyang smiled and set his eyes on Li Mingchang.

Li Mingchang asked, "Shaoyang, have you come up with any ideas again?"

"I think we can set a quota of 11,000 ore to be mined per person per year, and as long as the goal is achieved, it can be released early and the annual service can be replaced by a mission, so that these people will have motivation and be much more efficient. ”

"It's a good idea. Li Mingchang nodded.

"Also, I see that although there are many people in those mines, there are still a lot of free places, and there is a bit of a shortage of manpower, why don't we recruit some cultivators to mine in them, take action for the Earth Demon Country, and then hand over ninety percent of the share, what do you think?"

"This ...... The veins of the Earth Demon Country, let other people come in and dig it, isn't it?" Sun Qian hesitated, while Li Mingchang waved his hand.

"It doesn't matter, such a huge vein, even if my earth demon vigorously exploits it, I don't know when it can be used, and the army urgently needs these materials, and in a special period, it is feasible to work around. ”

"Grandpa Li is right, Shaoyang also thought that it was actually used in his own army, and it didn't have to be like the currency circulating in commerce, which could be cut into large pieces of demon cubes, and the standard demon crystal was time-consuming and laborious, which was really undesirable. ”

"You kid is also whimsical, but this can be tried, but you have to go to the army to discuss it with your father first, what else do you have in mind?" Li Ming asked with a long bearded smile.
