Although the process of making the magic crystal is temporarily unobtainable due to "secrecy", the rest of the technical academies do not keep it secret because it is not necessary.

If the magic crystal is a "storage battery", then the magic crystal is a "disposable battery". The magic technology without the magic core is just an extension of the magic array technology and the alchemy technology. Therefore, it didn't take much time for Green to learn these knowledge and skills, and he copied those key textbooks and sent them back to the territory through the communication mirror, and handed them over to Mona, who was in charge of education, and Harry, who was in charge of research.

If the civilization of the Kingdom of Northbod is equivalent to the Age of Enlightenment, then Grimm's territory is still in the age of ancient agricultural slaves when iron tools were not widely used - the gap between the two is too great. Therefore, even if he can't get the craftsmanship technology of the magic crystal, Green can still find a lot of technology from the academy that will help the territory.

In the blink of an eye, it's weekend again.

After a week of "grievances", Beladona found Green again.

"Daddy! Let's get out of here! Beladona said to Green with tears in her eyes, "People here are always bullying me. ”

Hearing Beladona's complaints, Green had no idea what to say. This week, Green has been keeping an eye on Belladonna's situation, although the instructor has been harsh on her, because she has been making trouble every now and then. To Green, it was perfectly normal training, but Beladona didn't seem to be able to adapt to that kind of life.

Clearly, Beladona didn't seem to be able to adapt to the training and life of the army, much to Green's disappointment. Originally, Green was counting on Beladonna to be a qualified army commander, but now it seems that ......

"That's fine." Green sighed, "Nana, since you don't want to go to school, then I'll send you back to the territory." ”

Hearing Green's words, Beladonna blinked: "Daddy is going back with me?" ”

"I'll go back with you with my clone."

"Hmm...... Doppelganger? Beladonna's face was full of displeasure.

Green: "Or do you want to stay here and train?" ”

"I don't want it! They always bully me! And I don't usually see my dad at all! Beladonna pouted, "You might as well go back to the castle here!" The people here are just so bad! ”

Hearing Beladona's words, Green could only smile bitterly: "The army, it's all like this." If you can't endure hardship, what kind of war will you fight. ”

Hearing Green's words, Beladona had a bitter face: "That...... I'd better go back. ”

"Hmm...... Let's go, then. Green stood up.

Beladona blinked, "Leave now?" ”

"Let's go through your withdrawal procedures first, and then go to the slave market to buy some slaves and send them back together by the way."

Originally, Green came to Angosari to destroy the place, but now that Green was going to stay at the school for a while, there was no need to carry the Demon King's Heart with him. Green plans to take this opportunity to send some of the supplies and materials he has recently collected back to the territory, and by the way, he can also buy some slaves with skills to go back.

Because of the labyrinth, the slave trade in the Kingdom of Palomia has almost completely disappeared. Even beggars who can't eat enough can take a weapon and go to the maze to live a life of licking blood with knives, and if they can't get along, they can even eat the food in the maze directly - although after eating the maze food, they can only stay in the maze for the rest of their lives, but at least they don't have to worry about starvation. The endless labyrinthine resources and the martial culture did not make the slave trade in the south not thriving. But in the north, it's a little different.

Although the north is vast and sparsely populated, there is no such thing as a labyrinth, which is a place where food can never be eaten, so some people are often forced to become slaves because of poverty.

Angusari's land is expensive, prices are extremely high, and there is no slave market, but fortunately, the Floating City is now staying near the fortress of Ray Eddy. There is a slave market in the Ryeddy Fortress.

After Greene withdraws Beladona from school, the two of them leave Floating City together and arrive at Ray Eddy Fortress.

As the only entrance and exit point on the Great Wall of Ray Eddy, Ray Eddy Fortress used to be the main commercial artery on the north and south sides, but since the north was occupied by demons, Ray Eddy Fortress has become much colder than in the past.

Soon, Green arrived at the slave market on the outskirts of the Ryeddy Fortress.

It was a huge prison-like building, and when Green explained his purpose to the reception at the door, a waiter enthusiastically led Green to the slave market.

"Oh~ Sir, you've come to the right place. We have the largest and most complete selection of slaves in the entire kingdom, and we have all the craftsmen and skilled personnel you need. The waiter introduced Green with a lot of words.

Green took Beladonna's hand and followed behind the waiter, looking around as he walked, "Is your business here deserted?" How come I haven't seen a single guest along the way? ”

Hearing Green's words, the waiter's expression stiffened slightly, but he quickly hid his expression: "You are really joking." The price of slaves is not cheap, so we have more and less guests here. Today there are fewer guests, which is normal. ”

"Is that so?" Green glanced at the waiter suspiciously.

The waiter smiled slightly: "We have arrived." ”

Suddenly there was a light at the end of the corridor, and a square as empty as a gladiatorial arena appeared in front of Green. There are also many iron gates and passages around the square.

"Please wait here for a while, the goods you want will be delivered shortly." The waiter opened his mouth and explained to Green.

"Hmm......" Green looked around, "this is the 'slave market' when you usually trade?" ”

"Yes."

"Hmm...... By the way, do you have any special slaves here that can be beaten? Or a slave who was once particularly able to fight, but is now crippled. ”

"Of course!" The waiter smiled, "But this kind of slave is not cheap. ”

"Hmm...... The kind of slave who used to be very good at fighting, but is now crippled, should not be worth much. ”

The waiter frowned slightly and looked at Green strangely: "Are you planning to heal them?" We do have such slaves here, but with all due respect, the money it takes to treat them can be more expensive than buying an intact slave directly! ”

"It doesn't matter. This kind of loyalty should be much higher than buying it directly. Green smiled, "Do you have any here?" ”

"Hmm...... Yes. However, it may take some time to reconcile. Such slaves were generally scattered among the slaves' families. ”

"Oh?" Green thought for a moment, "It's okay, if they're worth it, I don't mind buying their family with them." ”

Hearing Green's words, the smile in the waiter's eyes became even stronger: "Don't worry, we promise to satisfy you." ”

While chatting, an iron door suddenly opened, and a burly thug walked out of it with several slaves in shackles.

"Here comes the slaves." The waiter said to Green with a smile on his face.

Looking at these slaves who slowly came out, Green couldn't help frowning: "These people are the blacksmiths you are talking about?" ”

Two humans, one goblin. The human blacksmith Grimm is barely able to understand, but halflings and goblins? Are you sure these two creatures have enough strength to strike iron!?

"Oh~ It's a little incredible, but that goblin is indeed a blacksmith." The expression on the waiter's face was a little forced.

Green looked at the waiter beside him, then at the goblin.

The goblin looked up, gave Grimm a lifeless look, and then lowered his head again. Compared to the lifeless goblins, the other two human slaves were much more active.

Two very young-looking human teenagers stared at Beladona holding Grimm's arm with glowing eyes. The two teenagers who had been in prison for a long time looked very hungry.

"Dad, I don't really like the look in their eyes." Beladonna whispered to Green as she shrank behind her.

Hearing Beladona's words, the waiter's expression stiffened slightly, turned his head, and shouted angrily at the two human teenagers: "It's itchy skin!?" ”

The two human teenagers were startled and quickly lowered their heads, not daring to look at Beladona again.

Green smashed his mouth: "Isn't your food here too good?" The boys look in good spirits. ”

"Haha." The waiter smiled awkwardly, "Please rest assured. Both of them have families. As long as you buy them all along with their families, you can guarantee that these two craftsmen will not run away. You know, it's unlikely that such a technical slave would be tied up in chains. ”

Green pouted, "Come on." If it were a short-tempered person, it would be the corpses of the two of them that would be bought now. ”

"Haha......" the waiter laughed dryly.

Green glanced at the two human slaves, "Don't you have any dwarven slaves here?" ”

"Oh~ no kidding." The waiter pointed in the direction of Angsali, "If we have dwarven slaves here, those grumpy dwarven compatriots will smash this place." ”

Freedom is earned by force, not by the mercy of others. Both the dwarves and the elves are extremely opposed to the slave trade, so it is ironic that there are human slaves in the slave market in the kingdom of Northbod, but there are no dwarven slaves.

Ignoring the two human slaves, Green walked up to the goblin and threw an identification at the goblin.

No way!? Can you really strike iron?

Greene: "Goblin, can you understand me?" ”

The goblin looked up blankly and spoke in Palomian with a strange accent, "Yes." ”

Greene: "What's your name?" ”

"Gurgsky."

"How did you learn to strike iron?"

The goblin was silent for a moment, then spoke in staccato Palomyan language: "Village, no one, strike iron." ”

Green frowned slightly: "...... What food did you eat last night? ”

Goblin: "Water, food." ”

"It seems that the goblin's Palomian language doesn't seem to be very good." Green turned to the waiter.

The waiter smiled slightly: "A goblin who has a complete grasp of the Palomian language is not cheap. ”

"Hmm...... That's right, too. How much does this goblin cost? ”

"Don't you want these two blacksmiths?" The attendant gestured to the two human slaves.

"No, I suddenly figured it out. What I need is some inhuman race with a different aesthetic than me, who won't steal girls from me, not these guys who might dig into my corner! ”

The waiter looked dazed: "I don't quite understand your consciousness. It's just some slaves, how can they have a chance to steal a woman from you? ”

"I'm a slave now, but it doesn't mean I'll always be a slave, does it?"

Hearing Green's words, a hint of surprise flashed in the waiter's eyes: "It seems that you will be a generous host." ”

"Okay, let's talk about the price. We'll have to see the other slaves later. ”

When it came to the price, the waiter immediately came to his senses: "This is a goblin with iron-making skills, so this number is needed!" ”

The waiter held out two fingers.

"Hmm...... Two silver coins? The price is quite reasonable. ”

"You're kidding. Two silver coins can only buy one normal goblin! This is a goblin who can strike iron and speak some Palomyan language! Two hundred silver coins. ”

"Huh!?" Green raised an eyebrow, "Are you kidding me?" You mean it's a dwarf? Or is this goblin a master blacksmith? ”

"How can two hundred silver coins afford a dwarf? Not even a dwarven longsword could be afforded. ”

"Ten silver coins, I'm not interested in continuing to bargain."

"Sir, this is a goblin that can talk and strike iron!"

"You can keep this goblin." Green snorted coldly, "Do you have a list of goods here?" Give it to me directly, I'll just check the price from the list. ”

"Hmm......" At this moment, the waiter suddenly saw a figure standing behind the upstairs window, and the expression on his face changed slightly, "Please wait, I'll go get the list for you." ”

The waiter left in a hurry.

At the same time, in an office with a clear view of the situation in the slave market, a middle-aged man in a gorgeous dress was smoking a pipe and looking at the situation in the market, his brow furrowed.

"It's getting harder and harder to do the business of ordinary slaves now......" the middle-aged man sighed, "This damn world! ”

At this moment, the door of the office suddenly opened, and a burly man walked in: "Boss, I have inquired clearly, that guest is here to buy a blacksmith." ”

"Buy a blacksmith?" The middle-aged man's heart moved slightly.

Ordinary people will choose to buy female slaves or male subordinates who can help with the work even if they have money, although professional technical talents such as blacksmiths are precious, but there are very few people who buy them, and generally only those lords or mine owners will buy them - this kind of people are really rich people!

"This is a big customer!" The middle-aged man stood at the window, again carefully observing Green who was standing in the market and waiting.

After a brief observation, the middle-aged man turned around, pulled open the drawer, took out a booklet from it, walked out of the office, and went straight downstairs.
