"Let's take a look, this thing looks like a stone, but it has a powerful and mysterious power. The two brothers looked proud, and one of them patted the big black stone, and then walked to the crowd, and took out some iron nails from his arms.

"Look, right, this iron nail, you have to watch it! keep your precious eyes open!" the man smiled slightly, and threw a nail into the air.

The nail was in the air, but suddenly it turned around and quickly walked towards the black rough stone.

I heard a crisp sound, and the nail actually stuck to the black rock, and then the man smiled and opened his hand, slowly approaching the rock.

I saw that the iron nails in my hand suddenly left the man's hand, and under the traction of a force, they stuck to the black rock.

"See, see, see, this divine stone has a powerful power, everything that is iron, as long as it is close to it, it will be sucked away!" The big man laughed and said, "This is the power of the gods, this is the power of the gods!"

"Hmph, Lao Tzu doesn't believe it!" Just when the big man was boasting to himself, a disdainful voice sounded, and a person walked out of the crowd: "You must have done something! Lao Tzu has a newly bought kitchen knife here, if your divine stone can absorb Lao Tzu's kitchen knife, Lao Tzu will believe you!"

"Okay, then please!" said the big man.

"Hmph, you want to lie to me? I'll tell you, my father is the god stick king Dalin!" the man snorted coldly and stepped forward. However, at this moment, I only felt a huge force in front of me, and the kitchen knife in my hand flew out with a "whoosh", and then stuck to the stone.

At this moment, everyone present couldn't help but be stunned, and then they all let out a scream.

Seeing this situation, the faces of both brothers looked very proud, and Li Longxuan, who was in the distance, looked at it, and his brows couldn't help frowning slightly.

"See, see, see" the big man laughed and said, "This is the artifact, this is the power of the artifact!"

"I'm going to show you some other artifacts. He walked over to the car, took out a black piece, put it on the ground, took out a fire fold and lit it.

"Now, the time has come to witness the miracle, and now I will show you your second artifact, the burning stone!" As soon as the other party's words fell, the black stone was really ignited, and it emitted a strong smell.

"Damn, it's coal, it's coal!" Li Longxuan's face couldn't help but show a hint of ecstasy, this is coal, it's the coal he's been looking for so hard!

With coal, the steel he made will be even better, and with good steel, his guns will not be afraid of cooling problems and explosion problems!

There is also coal in the Divine Dragon Empire, but it is in the Divine Dragon Empire, not in the Cold Bone City! His own strength is only in the Cold Bone City, and he can't reach the Divine Dragon Empire!

Although he has been secretly buying coal from the Shenlong Empire, but those guys are too dark, the asking price is too high, obviously it is something that no one wants, but as soon as someone wants it, they immediately offer a sky-high price, if they can master a new coal mine, then they have one more way to make money.

Not only did he save money on buying coal, but he was also able to create a new trade route!

Li Longxuan couldn't help but be ecstatic in his heart, and then looked at the huge black rock, the joy in Li Longxuan's eyes became even stronger.

Nima, that's a magnet, but a real magnet!

Maybe for others, the magnet is just a thing that can absorb iron, but for Li Longxuan, it is definitely a kind of energy, a kind of wealth, and a thing that benefits the country and the people!

The conversion of magnetism and electricity, Li Longxuan learned it when he was in high school!

If you can get a magnetite, you can build a power farm!

Anyone who has studied physics knows that the simplest transmission is a motor! Li Longxuan still remembers when he was a child, when he installed the motor on the wheel of a bicycle to generate electricity.

If you really get a magnetite, you can make the entire Cold Bone City into a city that never sleeps! And those factories, once they have the support of electricity, the work efficiency of the entire factory is definitely a revolutionary change!

Although there is no water in the Cold Bone City, there is wind in the Cold Bone City, especially not far from the Cold Bone City, there is a famous Valley of the Wind, where the wind blows every day all year round!

That's a lot of motivation!

The wind drives the motor to generate electricity, and then connects the alternating current to the transformer, through the line to the cold bone city, and then through the transformer to connect the line to thousands of households.

As for the wires, those iron ore and copper mines, there is no shortage in Cold Bone City.

Of course, there are some troubles, that is, there are no insulators such as plastic in this era, but Li Longxuan is not worried about this.

Isn't there a Dharma saint at home? Isn't it claimed that there is nothing on the big 6 that she can't get? The problem of the plastic skin of the insulator and the wire is up to her.

If it doesn't work anymore, Lao Tzu will use glass as an insulator!

As for the electric light, I first use bamboo charcoal to make tungsten filament, although it can be brighter than tungsten filament, but it is almost the same. If it doesn't work, just use the magic crystal.

There are many kinds of magic crystals in this world, one of which is that they will glow when they come into contact with power, such as receiving the power of fire magic will emit red light, contact with the power of water magic will emit blue light, contact with the power of electricity magic will emit purple light, and magicians will distinguish a person from having no magic affinity according to this color.

There is also the ability to absorb power and store it for the release of magic crystals when needed. This magic crystal is simply a natural battery!

"Damn, if I store electricity in the magic crystal and use the magic crystal as a battery, wouldn't I be able to use a flashlight, an electric rod, and a tram?" Thinking about it, Li Longxuan couldn't help but feel excited.

Electricity, no matter what the era, is a kind of revolution!

Lao Tzu must have light and electricity! Li Longxuan couldn't help but shout in his heart.

In the past, I didn't dare to think about electricity, but now that I have magnets, if I don't get electricity, I'm sorry for myself.

"Wait until you take these two people to the city lord's mansion, and say that your highness wants to see them. Li Longxuan said to the soldiers beside him, a wicked smile appeared on the corner of his mouth.
