Louis's property in the city was mainly some handicraft workshops, and their most important industry was the farmland outside the city, which had a steady rent of thirty gold coins every year, and as for the workshops, I heard that some of them could be sold to other city-states, which were very popular and brought them good profits.

Feng Lide's family is even more unusual, as the largest family in the city after the lord, they ...... But it's just a 'big fisherman', which seems a bit small, but in fact, their family owns thirty large fishing boats and more than forty small fishing boats, not to mention this city-state, the basic fish supply of several nearby city-states is supplied by their family!

The word big family is no longer enough to describe their family.

Counting alone, there are more than 1,000 people in this city who eat at their house.

After chatting with Uncle Monet, then Lu Yu smiled and said, "Tonight, it is destined to be a ...... A night when a lot of things are going to change. ”

Uncle Monet was a little unclear in one sentence, and looked at Lu Yu back to his room with a puzzled face, he also walked back to his room, no matter what others were, he really couldn't sleep well this night.

......

"Well, that's how it should be. ”

Lu Yu took out a pen and paper and kept sketching.

"These workshops of Louie's family actually sell a lot of miscellaneous things, but the most important of them are some iron tools, kitchen knives, wood knives, axes or something, and some of them are blades, it seems that the craftsmanship is really good, it can be sold to many places, some people buy it, and it can be sold, it is not a difficult thing. ”

Xiao Ruan said: "So, is the young master ready to do something?"

"Hahaha, lift the lid on the top, and draw the bottom of the kettle, so that a pot of water can cool down as quickly as possible. ”

Lu Yu returned to the hotel, worked in the room for an hour, and then ran to Liya's room and woke her up.

Liya, whose hair was scattered, was full of doubts, not knowing what had happened in the middle of the night, but she was more nervous.

Lu Yu smiled: "Sister Liya, I have an idea, that is...... Co-operation with you, open a small shop. ”

Liya was stunned for a moment, and then smiled: "Hmm...... This is really a good way, after all, you have so much money, young man, if you open a store, you won't sit on the mountain, it's just ...... What kind of store do you want to open? Or do you want to sell my little store?"

Lu Yu shook his head and said, "This kind of ...... I'm not very proficient in it, and if I open it, it will cause jokes, but there are some things that I am quite proficient in, although I don't have much talent in the cultivation of the teacher, but in some other aspects, this talent is still good. ”

Liya's eyes lit up and she smiled: "Then you have to tell my sister what special skills you have." ”

She is like teasing a child, after all, in her eyes, Lu Yu is a child.

Lu Yu asked, "Then I have to ask Sister Liya, what is the most precious and valuable thing in this city?"

Liya thought for a while and said: "Well, the first thing that is valuable must be the land, if you have land, whether it is to grow food or trees, you will have a lot of income, and it is also very stable, which is really enviable." Secondly...... There is a saying in the city, that is, how big a ship there is, how big the sea is, the sea is also like farmland, it will give a reward to the occupier, the bigger the ship, the bigger the sea will have, and the better the output, so ...... The big ship is more important than the land. ”

"Oh, that's right, that's true...... But a ship isn't a shop or anything like that, is it?"

"Hehe," Liya chuckled softly, "I also answered your question directly...... But the most lucrative business is the blacksmith shop and the jewelry store. ”

Lu Yu was stunned for a moment, and said, "Blacksmith shops and jewelry shops, they are the most profitable?"

Liya said: "First of all, this jewelry store, jewelry is very expensive, you think, some jewelry just costs more than two taels of gold, if you sell, of course, it will cost several gold coins! As long as you want to buy something, it must be a big price, not big, but the value is very high, so it makes money." As for the blacksmith shop, it is a great profit, for example, a kitchen knife can only use half a pound of iron, and the raw materials can be bought without a copper coin, but the price of the kitchen knife itself is enough to ten copper coins, and the quality is relatively good, and it will be twenty copper coins, what is this? It is more than ten or twenty times the profit! If it is a blade, then the price is even more outrageous, and it is also made of iron, at most twenty or thirty catties of iron, to make a blade, but the price of one or two gold coins must be directly bought! This is ten thousand times more than the cost! So, that's the most lucrative business, because they're selling crafts, not things, and it's almost cost-free. ”

"I see...... That's a real ...... Good thing. ”

Lu Yu smiled.

Liya was stunned for a moment, and wondered, "What's the good thing?"

Lu Yu grinned, then asked Liya to lead him to the kitchen, reaching out and holding a kitchen knife in his hand from the knife rack next to him.

Lu Yu reached out and rubbed it, then ...... With a slight break, the kitchen knife is directly broken in half.

"Ahh

Liya's eyes widened all of a sudden, her face was full of incredulity, and distress, and then asked, "Why...... Why?"

But in his heart, he thought, this kid is really dangerous, he went up to bite the gold coin before, and then the kitchen knife was directly broken...... Does this guy just like to break everything around him......? Naughty kids!

Lu Yu smiled and said, "It's nothing, I'm just looking at its internal structure, uh-huh...... Got it. ”

The corners of Liya's eyes twitched, and she smiled bitterly: "What else can there be internal structure, this knife...... It's just a knife, to put it bluntly, it's just a piece of sharpened iron. ”

Lu Yu nodded and didn't say anything.

He really didn't know what he should say, yes, a place that was even more backward than another continent, where there was no civilization, and where there was still a kind of worship for metal itself, how could it have very high technology?

But Lu Yu was also a little reluctant and asked, "That...... Does Sister Liya know how this kitchen knife was forged?"

"Well...... Liya recalled, and then smiled: "Ah, I really know! I remember that I went to see it once because I was curious, and it was really powerful and complicated!" They first smashed some metal, and then put it in a spoon that seemed to be very big, and then they put it in the fire and burned it, and it burned and burned, and then the metal became molten iron, and then they poured this molten iron into a mold, and those molds were like the things I used to make cakes, and there were grooves in them, and they had a certain shape, and as long as the molten iron went in, the shape was fixed, and then what happened? By the way, wait for it to cool a little, then pour water on it to cool it completely, and then grind it with a stone to sharpen it into a knife!"

"Uh......"

The corners of Lu Yu's eyes twitched violently.

Liya smiled, "Isn't it difficult, complicated?"

Lu Yu took a deep breath, and then asked again, "That...... Sister Liya's kitchen knife is like this, so is there a better kitchen knife than this?"

"Of course there is! There are many more!" Liya nodded and said: "This one of mine is made of ordinary iron, of course, it is actually high-grade iron, and it cost forty copper coins at that time, and they sold it to me at such a cheap price because they knew me very well, and you ...... Ahem, there are some kitchen knives made of more precious metals, but those are for the rich and noble. ”
