Sometimes Rembert genuinely felt that this wizard in Boulder City was more suitable to be a politician than himself.

The two million UBS bonds were sold out as soon as they were sold. A certain chamber of commerce from Coldwind Castle even spent a lot of money to directly buy a million UBS bonds, as if he was not worried at all about the hundred or so bonds with a face value of 10,000 in his hands.

Originally, he was worried that if the two million UBS bonds could not be issued, his Karel family would have to set an example and buy these unsellable "pieces of paper" out of his own pocket, but now it seems that he is thinking too much.

If the king came to borrow money, the chambers of commerce and families in Boulder City guaranteed to hide everything, and they couldn't take out half a silver coin. But the person who borrowed the money was a wizard, and the result was completely different. It wasn't so much that no one was worried about the wizard's breach of contract, but rather that these families wished that Jiang Feng wouldn't be able to pay back the money in the end.

In everyone's mind, wild wizards are a proud and face-loving group, especially in front of mortals. Otherwise, Andorra would not have gone to the Norren continent to help a little-known small family for the sake of a promise made a hundred years ago.

To make the wizard owe a favor, that is an opportunity that no amount of silver can buy.

Early Sunday morning.

After eating breakfast in the restaurant of the city hall, Jiang Feng returned to the study and asked the servants of the city hall to find Du Wei.

After coming to the study, Du Wei bowed to Jiang Feng slightly.

"My lord, are you looking for me?"

Stopping the quill in his hand, Jiang Feng looked at Du Wei who was standing in front of the table and asked in a casual tone.

"How? Are you still used to life here in Boulder? ”

Du Wei was stunned for a moment, and then smiled, "Thank you for your concern, for businessmen like us who go from south to north, there is no problem of whether we are used to it." ”

"Then I'll rest assured," Jiang Feng nodded, and after a pause, he continued, "I need you to help me do something immediately, and let the plantation over there in Port Servit send a batch of potato seeds." ”

Before leaving Crocodile Island, he taught the fugitives from Baanville how to grow federal crops and how to breed some of them. Now, after many months, he has roughly estimated that the plantation should have harvested two crops in absolutely.

The Thorn Wasteland is located in an arid area, and it is difficult for ordinary crops to survive, so Jiang Feng plans to introduce potatoes, which are much superior in yield and drought tolerance compared to the "green barley" planted by those farmers.

Du Wei bowed his head slightly and said immediately.

"I'll do it."

After Du Wei left, Jiang Feng stayed in the study for a while, and was about to return to the bedroom, when he received a message from the servant from Fielding, saying that he was going to let him go to the alchemy workshop, and there was good news to tell him.

After hearing this news, Jiang Feng was a little surprised, what good news could there be in the alchemy workshop, now the flintlock pistol and smoothbore cannon have been handed over to the steel factory, only the black powder is still produced in the alchemy workshop, unless ......

Jiang Feng thought of an unlikely possibility.

With a hint of curiosity, Jiang Feng went to the alchemy workshop.

Sure enough, just as he had guessed, Fielding's research broke new ground.

In the alchemy workshop, the half-crouching Fielding was fiddling with something behind a metal doll that was only half his height, and he didn't notice Jiang Feng's arrival at all, but the apprentice who helped him with the tools on the side found Jiang Feng.

"Teacher, the wizard is here." The apprentice reminded in a whisper.

Fielding, who was squatting on the ground, heard this, and looked behind him, but the work at hand did not stop.

"Please wait a minute, I'm just short of the final fix...... Soon to be good! ”

Jiang Feng nodded and said in an easy-going tone, "Don't worry, I hope you can surprise me." ”

"That's for sure!"

After about ten minutes, Fielding wiped the sweat from his forehead, smiled from ear to ear, stood up and saluted Jiang Feng: "My lord, please enjoy Fielding's new work, Iron Man No. 1." ”

The corners of Jiang Feng's mouth twitched.

It seems that this guy's art of naming is not much better than his own......

But the name is all floating clouds.,Anyway, it's just a trial work.。

Patting the dust off his pants, Fielding activated the doll in front of him and said excitedly, "I've found the reason." When the mana flows along the inscription, the material becomes fragile, and the greater the amount of mana, the more obvious the weakening of the material's strength. Later I tried to engrave the inscription on a silver wire, and then through the inscription, and guess what happened? ”

Jiang Feng raised his eyebrows, and an interested expression appeared in his eyes.

"What happened?"

"Shake!" Fielding excitedly said, "I noticed that the silver filaments were vibrating up and down!" Later, I tried to pass the magic in the opposite direction and discovered an even more amazing phenomenon! The silver filament is also vibrating, but the cycle of vibration is just the opposite! I tried to engrave inscriptions on both sides of the same piece of material, and entered the same size of magic, and found that the problem of brittleness of the material was perfectly solved! ”

Hearing this, Jiang Feng probably understood what he meant, that is to say, the wave range difference between the two simple harmonic vibrations is exactly equal to half a cycle, and the waves cancel each other out.

"I tried to engrave the inscription on the steel produced in the blast furnace and set the inscription on both sides, one for control and one for drive, and then covered the inscription circuit with a steel casing. Although this makes Ironman more cumbersome and the skeleton is much larger than before, it also gives Ironman a more changeable movement posture. ”

As he spoke, Iron Man One was already moving, supporting his bulky body and dancing comically on the ground. Although it didn't look much aesthetic, Jiang Feng could still see at a glance that the technical content of this Iron Man No. 1 had far surpassed the previous design.

Even, in addition to the lack of controllable instructions, this puppet already has the rudiments of a simple robot.

However......

Its disadvantages are also obvious.

The end of the song.

Iron Man One did not disintegrate, Fielding walked quickly to Iron Man One, quickly checked it, and after finding that there was no problem, he was full of excitement and muttered to himself.

"I succeeded...... It worked! ”

Jiang Feng thought for a moment and spoke.

"Fielding, do you think you have a great idea?"

Phil was slightly stunned and nodded subconsciously.

He felt that there was no better design in the world.

Jiang Feng smiled and said softly: "Fielding, I admit that it is indeed good, especially since you solved the problem of vibration of the material, which is quite critical to the development of inscription technology. But what I want to say is, you can't just let him do one dance. From your design, if you need him to do a dance, you need to install a set of inscriptions specifically for it, and if so, how many separate inscriptions do you need if you want him to become a dance master? ”

Fielding's design is already very good in this world, but in Jiang Feng's opinion, this is far from enough, and Fielding's potential is far more than that. If you can only dance one dance, then this bulky big guy is no different from a music box, but the future of inscription technology is far more than that, in Jiang Feng's view, this is the technology on the idealistic side, the closest to the materialistic side of the technology, and its future is limitless.

Fielding was silent, he hadn't thought about it. If you want this Ironman to learn another dance, you have to erase all the inscriptions on its body and replace it with another one. However, he couldn't think of a better solution, and the size of the material only allowed him to carve so many inscriptions, unless he made Iron Man 1 bigger.

At this time, Jiang Feng spoke.

"Think of the equation for black powder, different combinations of chemical elements, and different chemical reactions that eventually occur. Why don't you try to find common ground between the two dances? And then take those commonalities out separately? For example, if you move your finger and kick your right leg, why not take out these inscriptions separately and put them on the front of the material, and then design a set of 'control circuits' that choose to call these inscriptions, so that Iron Man can think about it for himself, and after getting the command, should he move his finger or move his right leg? ”

That's it.

Rather than telling him the answer himself, he hoped that he would be able to draw conclusions through his own thinking. Creativity and ways of thinking are far more valuable than the conclusions themselves, both for individuals and for civilizations.

Jiang Feng didn't want to interfere too much and end up killing a genius's idea, and his achievements were far more than that.

Looking at Fielding, whose eyes were gradually brightening, Jiang Feng did not disturb him to think, and turned around and left the alchemy workshop.
