Time kept ticking, and before you knew it, days passed, and Lu En was busy during this time, and the auction took place as scheduled.

The dragon's blood and dragon scales, as well as many materials, were auctioned off, and Lu En earned four thousand two hundred and seventy-six Star Maple gold coins, and the dragon's blood was bought by a big man who heard the news, and Lu En learned from the surrounding population that the man's name was Uli, a very famous brewing master and pharmacy expert, and he developed many liquors and brewing seasonings, including eleven wines, three extremely strong clear spirits, a light fruit wine with floral aromas, five kinds of beer with diverse flavors, and a black fermented seasoning with the aroma of beans, Five kinds of brewing spices, I heard that he has the skill of alchemy 5.

These products made his breweries and wineries highly regarded by the upper class, and even the king praised the wines he made and paid high prices for them, so he was not only an alchemist and brewing master, but also the operator of a chain of wineries and breweries.

He used all the money he earned to invest in his alchemy laboratory, spending a huge amount of money to buy experimental materials, and in this way, he collected a lot of rare liquids, and this time the dragon's blood was no exception.

The one who bought the dragon scale armor was a knight lord from other cities, named Ai Din Bright Silver, a big nobleman in the Star Maple Kingdom, his strength was very weak, probably only level 1, and even level 1 was only forcibly pushed up by resources, but because he inherited the family's title and wealth, he usually likes vanity, and likes to buy all kinds of precious things to collect, although he can't use this kind of thing himself, he can hang it in the castle to show off, and he bids very high, this dragon scale armor is at least more than fifty percent premium, But it seems that he likes it very much, and after taking a picture, he put it on directly.

To be honest, this knight lord is really good-looking, handsome, tall, wearing dragon scale armor, he really has the illusion that he is a powerful combat professional, especially he still has long golden hair, to be honest, Lu En has to admit that this person is indeed very confusing, and his whole body is just like a pile of money, from boots to armor to rings, long swords, and even the cloak behind his back, all of them are magic items, Lu En suspects that even his underwear is a magic item.

But all in all, it was a bumper harvest, and the money was enough to build the factory he wanted.

Nowadays, the popular workshop of mankind is the practice of traditional craftsmen, for example, the training process of a typical blacksmith is quite cumbersome.

First of all, he needs to become an apprentice from an early age, during which he must absolutely obey the master's orders and help him, during the apprenticeship, there is generally no salary, but the master eats and stays, and the apprentice will continue to stay by the master's side for many years, like a follower, learn the technology little by little, and finally spend about twenty years to learn the master's technology, become a young man close to thirty years old, and finally go through an exam, you need to independently make a weapon or armor, and hand it over to the blacksmith association or the master himself for inspection, After passing the qualification, he was granted the qualification of a craftsman, and could practice independently, becoming a master of the workshop, and qualified to accept his own apprenticeship.

This method produces excellent craftsmen, each apprentice has to go through a long period of training, and the best craftsmen will also become professionals, forging tools or weapons with supernatural abilities, and possibly even magical equipment.

But there are also drawbacks, that is, the efficiency is extremely low, according to the information that Lu En investigated in order to find a suitable craftsman, there are only more than ninety stonemason masters in Larante, only five free people, and the rest are all affiliated with the United Chamber of Commerce or the Hall of Glow of Light, of which only twenty people are professionals, and these twenty people are all in the hands of the Hall of Glow and the United Chamber of Commerce.

Even if these masters are fully open, it is difficult to produce a large number of products in a short time, and they master different technologies with each other, each workshop has its own housekeeping skills, their own disciples must strictly abide by, and even defend with their lives, and those who violate will be abandoned by the craftsmen of the entire association, which also leads to the serious differentiation of their products, almost every thing made is different, very personal, abandoning the ability to produce quickly, and choosing boutique manufacturing.

This is Lu En's opportunity to gain a foothold, he wants to build not an ordinary factory, but an assembly line factory, for this reason, he specially did a lot of investigation, and finally decided what the workshop should do.

Quite simply, he had to make hammers and pliers, as well as ironmaking.

It's that, whether it's a stonemason, or a carpenter, or whatever, in short, a hammer that needs to be used in every way.

Lu En thought about this.

The main reason for this is that the army is about to come to Larante to station, and there will be a lot of business at that time, so both the United Chamber of Commerce and the Hall of Glow will seize this opportunity to get closer to the Holy Alliance and make a lot of money from it.

Just from the monster forest, ransacked the Demon King City, slaughtered the Holy Alliance army who don't know how many monsters, and now it can be said that it is very rich, and in Larante, he will definitely convert these materials into wealth, and then cash them into military salaries.

Among them, there are two things that make the most money, one is the sale of monster materials, and the other is the maintenance of military equipment, hundreds of thousands of troops, the equipment that needs to be reforged and repaired is by no means a small amount, but limited to the productivity of the artisan system, and the maintenance materials that Larrant City can supply in a short period of time are really limited, in this case, the United Chamber of Commerce and the Hall of Glow will definitely need to buy materials from other places.

So, instead of spending a fortune and shipping to other cities to ship to Larante, why not buy it here at Lune?

To seize this opportunity, you have to understand other people's needs, other people's desires, other people's motivations.

Others, including the local town hall in Larante, couldn't afford to quickly provide so many tools and fine iron to make armor.

You must know that the iron used to forge weapons and armor is not ordinary iron, but needs to be refined, this world is called refined iron, and Lu En observed and concluded that it is actually steel, and it is not very good quality steel.

Even if it is this kind of steel, ordinary craftsmen need to spend a long time refining to obtain, professional blacksmiths can use some kind of supernatural power to quickly make steel, but the number of professionals is scarce, there are only dozens of professional blacksmiths in the entire Larante, and then tools and steel will be temporarily in short supply, because the hammer for repairing armor also has to use steel, otherwise it will wear out quickly, and it will break down after a long time.

Therefore, only the Luen family can quickly mass-produce steel and mass-produce repair tools such as hammers.

Because - he has a blast furnace.

There is no blast furnace in this world.
