Challenge the wilderness to survive

"Dafang, crystal, we found crystal mine."

"Dafang, we found crystals."

A team specially responsible for the exploration entered the Yanlong City, gave a loud call.

Yueyang is the captain of this exploration squad.

After Xu Yi gave the Xia Dang and Xia Li to the black snake, Xu Yi let the Yanyang go out to find crystal mine.

Of course, there are other mines.

Various ores have a very important role in the development of tribe.

For example, Xu Yi wants to make batteries, all kinds of metal substances are required.

In short, the more metal material is, the more conditions and foundation of the development of science and technology.

Therefore, the moon is directly to the ore.

Found the crystal, and his home can also be used.

Well, in addition to Xu Yi, the second person can use the electric lamp.

Because Xu Yi promised, he will send a generator to the moon.

"Too good, come out to show me."

After Xu Yi heard, he rushed out in the first time.

With crystals, not only can make light bulbs, but also a telescope.

Well, you can make a big guy, then make a super big telescope.

Human process is limited, but with mental strength, Xu Yi can break through the limit of Earth's technology.

Have to say, mental strength is really impressive.

Xu Yi gave two storage capsules to the moon, let him use a storage capsule.

In this way, they can carry some ore back.

Of course, there are still many people back to crystals.

"Look, the big witch, very translucent crystal." The moon has taken a large transparent crystal.

"Sure enough, it is too good! Fast, hurry to get my studio." Xu Yi said.

During this time, Xu Yi made a few new things.

One is a blower, one is a fan.

After a blower, Xu Yi's boiler is more powerful.

The crystals back in the moon ribbon are high quality, and the light transmittance is very good, there is no impurities.

So, Xu Yi took a big crucible to start melting crystals.

"Yueyang, open the drawer, take the lights out."

Xu Yi stared at the crucible, and he didn't want to go to take the electric light.

At this time, the crucible is not hot.

I took out twenty electric lights in the moon, all made the threaded light.

As the temperature in the crucible is getting higher and higher, the crystal is gradually melted.

After softening, Xu Yi's mental force began to cut it out and then let it become a bubble.

Xu Yi picked up a light, let the two combine together.

The air inside, was smoked out.

To honest, there is no mental force, Xu Yi does not do this.

The biggest problem with incandescent lamps is the sublimation of the filament. Because the slight resistance difference on tungsten wire is different, the temperature is higher, the temperature is higher, and the tungsten wire is also rapid, so that the tungsten wire is thinner, the resistance is further increased, and the final order Tungsten wire is burned.

Later, it was found that the vacuum can slow down tungsten wire with an inert gas. Today, most of the light bulbs are injected into nitrogen, argon or helium.

Modern incandescent lamps are generally around 1000 hours.

However, the tungsten wire drawn from the spirit of psychoptic, there is no subtle resistance difference, and there is no problem that there is no sublimation and fuse.

However, this can only have witch spirit.

This also means this, this output is very low, not ordinary people can be enjoyed.

Ordinary people can have oil lamps.

The witch is too rare, even if it is to swallow the original tribe of the world, there are thousands of people, and the number of wors will not exceed one thousand people.

This rare witch is used to produce a light, which is really extravagant.

Of course, the things that the witch production itself is luxury, this logic has no problem.

"Dafang, this is the light bulb, it is too beautiful, you can turn the crystal as a bubble!" Yueyang looked at Xu Yi used a spirit to blow a glass bubble, his eyes were all straight.

"Yes, this is a complete electric light." Xu Yi moved it with mental strength, letting it fall.

After the temperature is lowered, Xu Yi screws it into the top of the lamp holder.

Xu Yi let the assistant put down the curtain of the studio and decline in the room.

Xu Yi plugged the plug into his dressed insertion, after power on, the light is bright.

"It's so bright, this is too bright, it is better than the bonfire." All people are shocked, they are not as fanatics like the lights.

Different months, because Xu Yi said that the electric light can make the car freely started.

Then, it means that its brightness is very high, otherwise, Xu Yi will not be so.

"This light is really high, it is estimated that there is 200 W incandescent lamp so bright." Xu Yi is still very satisfying to the brightness of the light, because it is really bright.

[Lao Xu this is also a punk, too show.

[I never thought that one day, I can see the spirit and industry such combination, too boss, I am too boy, you have laid a very advanced foundation for this world!

[I am squatting, I am so beautiful. You are really a spike other challengers. Your help for this civilization is too big. If human beings have such a character, we now estimate that Star immigrants are realized.

[Lao Xu, you are a new magical technology. No, you are actually the alchemist is right, right, you are alchemy, real alchemy!

[Lying in the trough, really, alchemy is not the case?

Xu Yi pulled the plug and let the sun re-entered the studio.

He needs to install the remaining lights on the light bulb, and then you can use crystals to make lenses.

At present, Xu Yi did not let the moon yang make light bulbs.

This is still more technically, because the existing crystal is relatively limited, Xu Yi also needs to use it to make ordinary telescope and astronomical telescope.

Xu Yi wants to see what is a state in this place to see the parallel time and space.

Soon, Xu Yi completed the production of bulbs.

Then, Xu Yi gave three months to the moon, after all, it is possible to damage.

The excitement of the moon is excited, and then ran in his home.

Xu Yi has long gave him a steam power generation system, the wire and the plug, and go back to take the light bulb.

Others can only silently envy, after all, hand-made generators or Xu Yi alone technology, have not yet passed to them.

However, with the success of the light, it must be taught.
