Lord: Marry the villain's daughter at the beginning?

Why is it said that the technology tree of this world is abstract?

Even in the Middle Ages in the previous life, there were already large water wheels. Later, hydraulic forging hammers were developed to help lower the price of plate armor for the knights.

But this world doesn't have that, let alone a hydraulic forging hammer, there isn't even a large waterwheel.

The reason is very simple, it's magic.

Who would invent irrigation tools when second-level, third-level, and even some magic apprentices can easily make it rain or divert water for irrigation with the help of magic circles and scrolls?

Just like when there was cryonics, no one would think of inventing refrigerators and air conditioners.

At least the nobles would never consider such a thing, because even if they really didn't have the money to hire professional mages or druids to irrigate their fields, the cost of spending some money to let serfs carry water for irrigation was lower than inventing a waterwheel.

Even if some clever farmers could come up with similar devices, they would be lost in history because they were too poor to realize them or because they were realized but could not be spread.

Especially in this world, feudal ignorance has an overwhelming advantage, and the development of civilization will be rigid and slow for hundreds of years.

The abstract technology tree is the concrete manifestation of this state.

Amid the exclamations of his subjects, Lind personally drove the keel waterwheel to bring the water from the aqueduct into the farmland.

No one exclaimed "magic, this must be magic" like they did when making sugar before.

Because the principle of the keel waterwheel is not complicated, as long as you understand the sprocket drive, you can do it roughly.

Many children even looked eager to try the pedal sprocket when they saw it.

But before the little boy could run, Reina had already taken off her boots and stepped on the wheel of the waterwheel.

"Oh, oh, oh, brother, look, this wheel is spinning so fast."

Reina pedaled the wheels quickly like a child who had just gotten a new toy, but because the waterwheel was only a prototype and Reina's body was too strong, the waterwheel soon fell apart and Reina fell into the field.

The knights immediately surrounded Reina who had a silly smile on her face. Most of the people around her wanted to laugh but didn't dare to, and could only try their best to suppress the corners of their mouths.

Only Linde slapped his forehead speechlessly.

Reina has really been letting herself go these days, and can even be said to be a little lawless, but fortunately she hasn't done anything harmful to others, at most she's just snatching toys from her older brother.

You know what, when Reina was snatching toys from the children in the territory, she really looked a bit like a villain.

Patting the dirt off her body, Reina said to Susan beside her: "This is good. Make me a sturdy one with black iron so that I can pedal it every day."

"Yes!"

Looking at Susan's serious expression, Linde really couldn't understand why Reina's knights could hold their nerve. Was it because they were used to it?

"Brother, do you still have this kind of toy?"

Looking at Rena's expectant face, Lind did not correct Rena's mistake, but thought about whether he could make the bicycle in advance. Although it certainly could not be mass-produced and the bicycle had no practical significance without road construction, it should not be a problem to make one for Rena to play with.

After all, he is the financial sponsor, so he must be coaxed.

After that, Reina walked around the keel waterwheel and asked again: "Brother, do you think we can add a stick that rotates with the sprocket, put the other end of the stick in the river of tears, and use the water flow to drive the sprocket to rotate?"

"Transmission rod?"

Lind almost subconsciously mentioned the device that Lena mentioned.

"Yes, that's what I mean. Brother, you are really a worm in my stomach!"

"That's a roundworm..."

Linde, who was a little shocked that Rena was not a fool just now, turned back to looking at her as a fool.

"But in that case, the waterwheel you mentioned also needs to be modified."

Reina picked up a branch and started writing and drawing on the ground.

The more I draw Lind's expression, the more terrifying it becomes. Yes, it is terrifying.

Just by drawing a picture casually, Reina had figured out the rough model of a waterwheel driven by a water wheel.

This is no less than a fool deriving a formula or theorem on his own.

Could it be that this fool is really a genius?

You have to know that Lind had asked in detail before. There is nothing like a waterwheel in this world, but Lind only gave a theoretical basis and a model, and Lena had actually designed a tool that had never been seen before.

"If what I drew is feasible, can I modify it and use water flow to forge steel and armor?"

Shit! While Linde was distracted for a moment, Lena's mind had already jumped to the hydraulic forging hammer, and she had even started drawing the design.

"Ms. Lars, how did you come up with the idea of ​​using water power to forge steel?"

Linde's expression was already quite serious, but Lena smiled sheepishly and said, "After all, our Lars family used to be blacksmiths. Grandpa always told me that the family craft should not be lost, so that we can still make a living if we fall into poverty in the future."

"..."

For a moment, Linde suddenly suspected that Lena's stupidity was hereditary. Would the eldest daughter of the Grand Duke of the North have to work as a blacksmith to make a living just because she was down and out?

But seeing Reina's silly smile, Linde suddenly understood Grand Duke Lars who was far away in the capital. He might be serious...

Watching Reina's constantly improving sketch, Lind also picked up a branch and joined in. With Lind's help, the sketch of a hydraulic forging hammer device that could theoretically work was completed.

During the course, Linde also supplemented Lena with some physics knowledge, and Lena understood it instantly at an astonishing speed. She was even able to apply it to other situations, and Linde, who was not a physics major, was defeated step by step.

Reina is truly a genius, in the “physical” sense.

"Although it's unlikely to run smoothly, to be honest, are there really materials that can support speed change and transmission now? If not, it's just a large toy."

Linde looked at the sketch and felt sorry for himself.

However, Reina immediately responded, "The materials are not difficult. You can use those alchemical materials. As long as you tell them what you need, those alchemists will be able to make it for you. It's just a matter of price."

Then Reina smiled confidently: "But for the Lars family, money is not a problem."

Linde then remembered that there really was magic and alchemy in this world, so he nodded and said, "Then let's go to the downstream town of Fasen tomorrow. I happen to have some other ideas that require a lot of alchemical materials."

"Fason Town? Are we going to the Champagne Fair?"

Reina's energy seemed to be endless, and she jumped up and down excitedly beside Lind, seeming to be eager to try.

"Not entirely. I have something to discuss with Viscount Jefferson of Farson Town. Of course, I also have to go to the Champagne Fair."

Hearing this answer, Reina immediately said excitedly: "Go, of course, I haven't visited the civilian market yet, I will go pack my luggage right away."

As soon as she finished speaking, Reina ran away with a group of knights. Linde had no choice but to shout: "I will be back the same day, no need to pack."

The Champagne Fair is a well-known fair in the western part of the North, but the location of the Champagne Fair is not fixed. Instead, it is held in rotation in the territories of lords known as Champagne nobles. This time it happened to be the turn of Lind's downstream neighbor, Viscount Jefferson of Fassen.

Although he was a viscount, Jefferson made a fortune from the Champagne Fair, and even some earls and marquis had to borrow money from Jefferson.

Moreover, the Champagne Fair is not just a place to sell wine, nor is it just a market. It has developed into a commercial activity. There are not only various shops but also performances such as circuses.

Because she had strict family education since childhood, all Reina knew about the market came from knight novels, so she was looking forward to this trip very much. At dawn the next day, she dragged Linde, who was still asleep, onto the boat.

Even after getting off the boat, before he had time to say hello to Jefferson, Lind was dragged to the market by Lena.

In the market, all kinds of stalls are densely packed together, and the hustle and bustle of the market and the noise of the crowd come together to form a prosperous and lively picture.

There are farmers setting up stalls selling colorful fruits and vegetables, vendors displaying various poultry and livestock, and craftsmen displaying their works such as wood carvings, pottery, leather products, etc. at their stalls, attracting the attention of passers-by.

You can even see some special stalls like the healer's stall, the wizard's stall, and the prophet's stall.

"I couldn't even sense any magical fluctuations from those mages at the stalls. How amazing!"

Reina was amazed at a wizard's stall that sold amulets that came with divination.

"That's a liar."

Linde pulled Reina away speechlessly.

Each of Reina's knights already had a pile of strange handicrafts in their arms, but Reina was still shopping and looking around.

In fact, these handicrafts are not as exquisite as the ones in Reina’s home. If she saw them in the royal capital, Reina would not even look at them.

But Reina still bought it, because the eyes of those who sold handicrafts were exactly the same as the eyes of the people when Reina governed the gray-collar workers. It reminded Reina of herself who could not do anything well at that time. This made Reina want to do something for these people, but in the end she could only spend money to buy their cheap handicrafts.

The market was lively, but not what Reina had imagined.

Weapons and bottles of wine were flying, there was swearing and fighting everywhere, and there were probably more pickpockets than guests.

Mercenaries and adventurers are not at all as generous as described in knight novels. Instead, they come in groups to threaten sellers with no background. The champagne nobles manage the market and do not allow zero-dollar purchases. So they ask these merchants to give a 50% discount. If they cannot give a 50% discount, they will give a full discount. This is free trade.

Originally, Reina thought that the old soldier beside Linde's claim that he had ridden a dragon was outrageous, but she didn't expect the mercenaries in the tavern to claim that they had killed dragons, bathed in dragon blood, and now had golden guns that could fly at night...

Lena didn't hear what happened next because Susan covered her ears. But even Lena felt that the man was lying, because he was just like the old soldier next to Linde, hesitating and unable to say what a dragon looked like.
