Chapter 34 The Dynamite Project

It is good to have spells. Li Xian no longer needs the help of others, and has easily produced several simplified versions of electric lights. Of course such a simplified version has many, many problems.

For example, not to mention ugly, the air in the bulb is not clean.

"Fortunately, the filament made of stainless steel can be used for at least a few hours. It is enough for experiments and so on. It is just a rare thing for the ground turtles. With jade lamps, it is difficult to find a market for electric lamps for the time being."

When Li Xian returned to the research room with a few lights, he was stunned. What do you think Li Xian saw? I saw two wires encircling the thickness! Yes, Li Xian can be sure that it is the wire, but it is not wrapped with the worst quality linen, but the highest quality silk.

Two thick "wires" extend from a one-meter-sized "four-element generator" and are buried in two large pits, one in the south and the other in the north, or mines.

The wire is thicker than the "generator", Li Xian was an eye-opener!

Even so, these "researchers" are far away from the wires and dare not approach them.

I... convinced! Li Xian only felt that crows were flying all over the sky, covering the sky and blocking out the sun; when it comes to being afraid of lightning, cultivators are definitely second to none. But it's weird that you are afraid of being like this.

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

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 a problem. 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, it was Xu Ren who made a proposal that was barely acceptable to everyone. The voltage is represented by "thunder"; the resistance is represented by "flash", and the current is of course "electricity" as the unit.

It is stipulated that the voltage of the first successful Sixiang generator is set to 100 voltages, the current when the energy output is equivalent to one horsepower is 100 currents, and the resistance is 100 resistances; the rest can be deduced by analogy. (These two paragraphs can be skipped)

With electricity, everyone immediately made a model of a simple electromagnetic eddy current heating furnace, and used electromagnetic induction to heat a bit of iron for experiments; the result shocked everyone.

"It's amazing, there is no aura fluctuation at all, and the iron block melts!"

"Is this the electromagnetic force? No wonder the young master made us swear to keep it secret."

"This electric light is also very miraculous. Electricity is really amazing. Master, can electricity replace aura for cultivation? And if you use electricity for cultivation, don't you need to fear the punishment from heaven?"

This is a great question! Li Xian also had to admire this person's association ability. Everyone looked at Li Xian again, with anticipation in their eyes: Yes, if you use "electricity" to practice directly, of course you don't have to care about thunder punishment and other catastrophes; and thunder punishment almost occupies seven of the catastrophes. become.

Li Xian smiled wryly: "Don't look at me, I don't know, but I'm also looking forward to it; everyone can study it if you have time, but be careful, don't encounter the 'Heavenly Tribulation' in advance."

Li Xian's teaching lasted more than five days. After everyone understood the basic issues, they were ready to start researching the first "ultra-high temperature melting furnace imitating sky fire". Everyone's work enthusiasm is extremely high, and their expectations for the future are unprecedentedly strong. The idea of ​​using electricity to practice directly has been buried here!

For a moment, the entire Qingyun Valley was filled with colorful clouds of joy.

"In 30 days, overcome the wire problem!" This is the slogan hanging on the wall of the research room.

When everyone was studying the wires, Li Xian finally thought of gunpowder in his busy schedule—or Li Xian had thought of gunpowder a long time ago, but he was busy with the research of wires a while ago and couldn't take care of it; on the agenda.

Although there are practices and spells in the fairyland, the power of gunpowder should not be underestimated. At least the sniper rifle is still a deadly threat to the Foundation Establishment Stage, and it is also a considerable threat to the Golden Core Stage; flying with a sword and killing people in the air are the supernatural means of the Golden Core Stage, but they are not as good as cannonballs. Therefore, after repeated calculations, Li Xian felt that if he had a gun force, he could almost run rampant in the Great Xia Kingdom, or even the eastern part of Yingzhou.

The gunpowder is very simple, and Li Xian quickly completed it, and the explosive power is very impressive.

But Li Xian always felt that something was wrong, and he couldn't tell what was wrong; after much deliberation, he finally found Xu Ren for advice, and even brought some finished products he had made.

"This gunpowder technology must not be developed!" Xu Ren immediately cut off Li Xian's thoughts. "Think about it, it didn't take long for you to make colorful lights before someone imitated them.

And the ingredients of your gunpowder are clear at a glance, and the foundation-building monks can understand the ingredients after a simple study. Once you understand the ingredients, your guns and cannons will soon be imitated. After all, the ingredients of gunpowder are everywhere!

At that time, what do you do? "

"Ah!" Li Xian finally realized suddenly, oh my god, I forgot about it. Yes, gunpowder technology can be easily imitated, so gunpowder technology must not be developed. There are still some troubles in the world of cultivators!

But Li Xian did not give up the idea of ​​a sniper rifle; gunpowder is not enough, there are also chemical explosives such as TNT, gunpowder, and chewing gum explosives. But it will take a long time to wait until the current industrial system is complete, and then we can let go of the development of chemical matters.

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

"Sir, I have another thing here called concrete, which is an item developed from the dust of the earth's lung outlet (crater)."

With that said, Li Xian told the situation of the concrete.

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

This time Xu Ren finally looked ecstatic, "Good thing! Young 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 those walls built with magic?"

"Features? Uh..." Li Xian tried hard to think, and finally thought of the difference; the city walls and military fortresses are very "old", and the city walls are all made of huge rocks. On the other hand, the walls built with spells seemed to be smooth and new.

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

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

It's just that the spell construction is fast and the cost is very low, so it is widely used, but it will only be used for low-level construction.

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

If you could actually make concrete, it would be a hit. Not to mention anything else, just saying that the concrete can be poured casually, and many defensive formations can be directly buried in the wall, making the formations stronger.

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

I can tell you with certainty that concrete is bound to sell well. Even getting it wrong will cause a lot of trouble! "

Li Xian's eyes became brighter and brighter, and finally he continued: "The ingredients of gunpowder are all natural and can be easily deciphered; but the concrete is fired, and the components are mixed and difficult to decipher!"

"Yes. So, hurry up."

"good!"
