"Thank you for saving Cloud Dream Harbor." An old man over sixty years old nodded excitedly, his hair was gray, and tears flowed, "My grandson was still doing business in Yunmenggang before, if it weren't for that mysterious thing you invented, Lord Weigong, I'm afraid my grandson would die at the hands of pirates." ”

"Thank you, Lord Emiya, I am a member of the navy, and it is especially regrettable that I did not participate in the battle of Yunmenggang this time, otherwise I would have been fortunate enough to witness you using the radar sword!"

"Emiya-sama, thank you......"

……

Wei Gong has never enjoyed the treatment of everyone like today, as if in the original world, he suddenly became popular overnight and became a hot star.

The better thing is that the people of the Dream Sword Country are relatively civilized, they did not come up to surround him like fanatical star chasers, but more through the respect released by their eyes.

That kind of respect, it's like looking at a-

Hero.

Emiya never imagined that one of his radar swords would be so effective and could cause a war to change dramatically.

This feeling is good for no reason, and it is happier than selling hundreds of swords yourself.

Don't...... Is this what it's like to be a hero?

He couldn't help but think of Spider-Man, Superman, Iron Man, Black Widow, Aladdin......

……

At this moment, in a small teahouse upstairs on the side of the street, the eyes of two people were watching what was happening below.

One of them was a sturdy man, dressed in a white coarse cloth robe, with a white forehead guard tied to his forehead, and a ponytail slanted over his shoulders.

And across from him sat a young man of small stature, about fifteen or sixteen years old, with a shallow scar on his forehead, thick eyebrows and big eyes, very handsome.

It's just that there is a hint of disdain between the eyebrows.

The young man asked, "Is that Emiya famous?" How I haven't heard of it before. ”

His voice was very loud, and Xiao Er, who was pouring tea on the side, turned his head when he heard it, and a proud smile appeared on his face.

"Of course, it is precisely by relying on him that we can win this battle, of course, the most important thing is that Your Majesty is wise and the Metropolitan Governor is well commanded. If you talk about the battle that took place that night, it can be described as thrilling......"

He gushed about what happened in Yunmenggang a few days ago, although he was also hearsay, but he spoke vividly and immersively.

The older man listened with relish, only the younger one turned around and didn't continue to listen to his story, but just looked at the emiya below.

The young man who was surrounded by everyone below had starry eyebrows and sword eyes, a delicate face, and a slender body......

There was a hint of jealousy in his eyes.

After Xiao Er left, he turned his head to look at the elder and said in a low voice, "Brother Lin Bei, do you think that after we came to the Dream Sword Country, the people here are not the same as the legend?" ”

"Yes, Brother Chen Xi." Lin Bei nodded, and said in a heavy tone, "I thought that the people of the Dream Sword Kingdom should be the most dissatisfied with the royal family, but today, it is not like this, you look at their eyes, full of reverence for the new emperor." ”

He paused for a moment and frowned, "I don't know why, I always feel a sense of foreboding." ”

Chen Xi's body twisted, sweat broke out on his forehead, "We won't run in vain and live up to the hope of the lord, right?" ”

Lin Bei smiled with relief, "Don't worry, you'll know when you go to see the branch of the Dream Sword Kingdom later." ”

The two of them finished paying, drank the last bit of chrysanthemum tea, and then stood up.

……

Mengjian Country is not as prosperous as Chongjian Country and Tianjian Country, so there are no big material merchants like Mingbao Zhai, there is only one material street, in which many different material shops live, and there are different imports according to their different strengths.

In addition to these private material dealers, there is only the largest state-owned enterprise left, [Mengjian National Material Workshop].

Wei Gong decided to go shopping for a while, and if he didn't have the right materials, he would go back directly to find Jian Rin Sakura, and then the information would be directly transmitted to his Qiankun Mirror, saving a lot of effort to find goods.

According to his vision, two different power supply devices can be used.

One is called a generator.

One is called a battery.

Generators need magnets and wires, and the principle of current generation is also very simple, by doing work, let the wire cut the magnetic inductance line, it will produce the directional movement of the charge in the wire, so as to form electrical energy.

Doing work requires a large power plant, and Emiya aims at two more effective energies:

The first is the use of heat energy, which is also the most basic way to generate kinetic energy, which is used to promote work and convert it into electrical energy. Thermal energy source, he wanted to go to the market to find some good materials.

The second is the use of tides and ocean currents, Mengjian country has a unique coastline, the sea water flow in the east has been maintained in a certain high-speed range for many years, especially the two black tides in spring and autumn, which not only bring rich marine resources to the whole country, such as large fish, but also bring them rich marine power.

It's just that there was no means to use it before, so the people of the Dream Sword Country were a little afraid of the excessively fast flowing sea, but Wei Gong thought to himself, there is no complete garbage in the world, only misplaced resources, if used properly, the ocean power generation alone is enough to support the electricity consumption of the entire Dream Sword Country.

Thinking of this, Wei Gong frowned, out of the consideration of a businessman, he couldn't completely dedicate himself to the Dream Sword Country, and then he had to discuss the construction and return of the Ocean Power Station with Jian Rin Sakura.

When it comes to batteries, it takes a genius idea and material testing again and again.

Batteries use chemical principles, and there are two basic ones:

First, the potential difference between the two poles is formed.

Second, there is a conductor connection.

The conductor can be a liquid, a solid conductor, or even a gas if the potential difference is large enough.

Ordinary batteries have a limited amount of power to meet Emiya's needs to open a factory, and he is looking for materials that can produce redox reactions, and they can provide a large amount of reserve electricity.

If it was placed on the original earth, such a battery structure might be more difficult, otherwise the battery equipment would have to be made very large, but this is the world of fairy swords.

There are a lot of amazing materials that can transform the impossible into the possible.

All you need is a pair of discerning eyes and a strong mind.
