It is good to have spells. Li Xian has no need of help from others, and has easily produced several simplified versions of electric lights. Of course there are many, many problems with this simplified version.

For example, it is not ugly to say that the air in the bulb cannot be cleaned.

"Fortunately, using stainless steel as the filament, it can be used for at least a few hours. It is enough to do experiments. It is rare to show the turtles. With the jade lamp, it is difficult for the electric lamp to have a market for the time being."

When Li Xian returned to the laboratory carrying a few electric lamps, he was stunned. Do you see what Li Xian saw? I saw two wires that hug each other! Yes, Li Xian can be sure that it is a wire, but it is not the most inferior burlap, but the highest quality silk.

Two thick "conductors" extend from a one-meter-sized "four-elements generator" and are buried in two large pits-or mines-one south and one north.

The wire is thicker than the "generator", Li Xian has opened his eyes!

Even so, these "researchers" are too far away from the wire.

I... served! Li Xian only feels that the crows are flying in the sky, covering the sky and covering the sun; to say the fear of lightning, the innocents are absolutely second to none. But you are afraid of this, it is also wonderful.

"Come here, come here, come here, I will give you the knowledge of electricity!"

Needless to say, Li Xian began to explain the relevant knowledge and common sense of electricity, electromagnetic induction, electromagnetic eddy current heating, voltage, safe voltage, current, resistance; of course, electric lights are indispensable.

But Li Xian also encountered problems. What units are used to express voltage, current and resistance? Obviously, this unit cannot be copied directly, and the definition of voltage resistance is also different.

In the end, Xu Ren made a proposal that was barely acceptable to everyone. Voltage is represented by ‘thunder’; resistance is represented by ‘flash’, and of course current is measured in units of “electricity”.

It is stipulated that the voltage of the first successful four-image generator is set to 100 voltages, the energy output is equivalent to 100 currents at one horsepower, and the resistance is 100 resistances; the rest is analogous. (These two paragraphs can be skipped)

With electricity, everyone immediately started to make a simple model of an electromagnetic eddy current heating furnace, and heated a little iron block through electromagnetic induction to make an experiment; the result surprised everyone.

"It's amazing, there is no aura fluctuation at all, the iron nuggets melted!"

"Is this electromagnetic force? No wonder the young master asked us to swear secrecy."

"This electric lamp is also amazing. Electricity is really amazing. Master, can electricity replace spiritual energy to practice? And if you practice with electricity, do you not have to be afraid of punishment?"

This is a good question! Li Xian also had to praise this person's ability to associate. Everyone looked at Li Xian again, and all looked in his eyes: yes, if they used "electricity" to practice directly, of course they wouldn’t care about the sky-tribulation like thunder punishment; to make.

Li Xian smiled bitterly: "Don't look at me, I don't know, but I'm also looking forward to it; everyone should study it when they have time, but be careful, don't encounter the'Sky Tribulation' in advance."

Li Xian's teaching was more than five days. After understanding the basic problems, everyone was ready to study the first "ultra-high temperature melting furnace that imitates sky fire." Everyone's work enthusiasm is extremely high, and the expectation of the future is also unprecedentedly strong. The idea of ​​using electricity to practice directly is buried here!

For a time, the entire Qingyun Valley was filled with colorful cloud-like joy.

"In 30 days, overcome the problem of wires!" This is the slogan hanging on the wall in the laboratory.

When everyone was studying the wire, Li Xian finally had a busy time thinking of gunpowder-or Li Xian had thought of gunpowder for a long time, but I had been busy with the study of wire a while ago, but I couldn't take care of it; now I finally have time to prepare gunpowder Put it on the agenda.

Although Xianyu has practice and spells, the power of gunpowder is still not to be underestimated. At least the sniper rifle still has a fatal threat to the foundation period, and a considerable threat to the Jindan period. Flying the sword and killing people in the air is the magical means of the Jindan period, but it is not comparable to artillery shells. Therefore, after repeated calculations, Li Xian felt that if he had a gun unit, he could almost rampage through the Great Xia Kingdom or even the east of Yingzhou.

Gunpowder is simple, Li Xian finished it quickly, and the explosive power is considerable.

But Li Xian always felt that something was wrong, and he couldn't say what was wrong; after thinking about it, he finally found Xu Ren to ask for a plan, and even brought a little finished product he made.

"This gunpowder technology can never be developed!" Xu Ren cut off Li Xian's thought for the first time. "Think about it, how long it took you to get the lantern, someone copied it.

And the ingredients of your gunpowder are clear at a glance, and the monks in the foundation period will understand the ingredients after a simple study. Understand the ingredients, your guns and cannons will soon be imitated. After all, the ingredients of gunpowder are everywhere!

At that time, what did you do? "

"Ah!" Li Xian finally realized, I rely on it, and forgot about it. Yes, gunpowder technology is easy to imitate, so gunpowder technology can never be developed. There is still some trouble in the world of comprehension!

But Li Xian did not give up the idea of ​​a sniper rifle; gunpowder does not work, and there are chemical explosives such as TNT, ******, and chewing gum explosives. But this has to wait for a long time. It is necessary to wait until the current industrial system is complete and then let go of the development of chemistry.

But there are too many things in Li Xian's mind, besides gunpowder, there are...

"Sir, I still have something here called concrete, which is an object developed from the dust at the exit of the lungs (crater)."

With that said, Li Xian told the concrete.

Finally, Li Xiancai asked, "Sir, I think everyone uses magic to build walls. Do you say that this concrete has a future?"

This time Xu Ren finally looked ecstatic, "Good thing! Master, think about it, what are the characteristics of the walls of Wuyang City and the walls of Anyang Frontier Fortress? What are the characteristics of the walls built with spells?"

"Characteristics? Hmm..." Li Xian tried hard to think about it, and finally thought about the difference; the city walls and military fortresses are "old", and the city walls are all made of huge rock barriers. On the other hand, the walls built with spells seem to be smooth and integrated, and they are all very new.

One is very old and the other is very new. This is obviously different and problematic.

Xu Ren saw Li Xian's suddenly enlightened expression and smiled slightly: "Think of it! The walls formed by spells have a short lifespan and are easily destroyed by spells. When the power of the spell is exhausted, the walls will collapse.

It is only widely used for its rapid construction and low cost, but it is only used for low-level construction.

However, important buildings, such as frontier fortresses and palaces, are still built with boulders. Moreover, the walls built by boulders can also be attached to defensive formations; the walls built by spells can no longer be attached to formations.

If you can really make concrete, it will be very popular. Not to mention, just saying that concrete can be poured at will can bury a lot of defensive formations etc. directly in the wall, making the formation stronger.

Moreover, concrete can also add reinforcement, fill gaps, repair old city walls, bond stones, and be used anytime, anywhere.

I can tell you for sure that concrete is bound to sell. Even failing it will cause great trouble! "

Li Xian's eyes are getting brighter and brighter, and finally he himself said: "The ingredients of gunpowder are all in nature and can be easily cracked; but the concrete is burned, the ingredients are mixed and difficult to crack!"

"Yes. So hurry up."

"it is good!"
