The Return of the Black Technology of Immortal World

The result was simple and beyond Yang Qing's expectations. He never expected that such a simple alcohol extraction and purification would yield a reagent that could accurately measure the concentration of aura.

Although its measurement range is still not accurate enough, it can only reach two digits after the decimal point, which does not meet the accuracy requirements of many precision experiments, but for Yang Qing now, this is enough, and if it continues to be purified, it will not be enough. It's beyond his ability.

Without suitable sealing materials, accurate thermometers, and zeolite that absorbs moisture, alcohol cannot be purified to the level of anhydrous alcohol, and organic solvents will inevitably be doped with moisture, which will dissolve Some original impurities will pollute the reagent, which will reduce the accuracy of the reagent.

You must know that the prehistoric world is still in an agricultural society, and all these tools are handcrafted, which is already very good, so how can there be so many picks?

Although even in modern society, handcrafting is sometimes a symbol of precision, let alone in the prehistoric world with extraordinary power, let alone fairy magic, even in the secular world, there are supernatural powers that can be handcrafted. A craftsman of precision objects.

It's just that such a master can't be found on the mountain of the outer gate. There are spells on the mountain, which are very convenient when refining items. No one will deliberately pursue the skills of mortals.

It has to be said that the application of magic is really convenient, just like the experimental equipment that Yang Qing needs, and he can easily get it from those brothers who practice acrobatics with only a little money, but to go further, others must participate, It's too late for him to keep it secret now, so naturally he doesn't dare to reveal it easily.

This disconnection between high-level and low-level productivity has a great relationship with the deliberate control of the upper level of the prehistoric fairy world. The bottom of the prehistoric mortal world is still in a feudal society. The level is still almost the same as that of the Ming Dynasty in the east on the earth.

In such an era when science has not yet started, what is learned in the academy is small talk, loyalty, filial piety, and righteousness. The knowledge of craftsmen is also called strange skills. The only way for the people to progress is to practice martial arts for a few lucky people. Fighting, taking an exam to become an official.

Probably the only difference from Blue Star's ancient times is that whenever there is a major natural disaster, floods and droughts, there will be real monks who will come forward to perform Taoism, so that those more important places will not be fruitless. With a little help, the population density of this world is much higher than that of the Kangxi and Qiang Dynasty during the first population explosion in ancient times, but people don't need to eat sweet potatoes and sweet potatoes, they eat rice grains, and their physical fitness is also higher than that of that period. People are much better off.

Among these residents in the mortal world, about one or two out of a thousand people will detect their spirituality when they are young, and then embark on the real Qingyun road of cultivating immortals. In fact, all the calculations of the upper layers of the fairy world are actually for this few thousandths of suitable people. In their eyes, the people cultivating immortals are the only ones who can be regarded as the real kind, and the others are just livestock. Naturally, they will not make great efforts to increase productivity in order to make them live more comfortably, thereby reducing the generation of spirituality in the population. proportion.

There is no systematic professor. Although this method of concocting medicinal materials with spirits has become popular in the world, no one will use it to extract psychic herbs. Even those adults don't know, let alone those who have just recognized it. The word child.

Among junior cultivators like Yang Qing, those who have successfully established their foundations and started to cultivate Qi can slightly sense the existence of spiritual energy with their own abilities. Their induction is far less sensitive, but these people are more sensitive than those at the bottom. The status of handyman is much higher, and there is a place with rich aura to arrange it, so you don't need to find it yourself.

And the bosses who can really sense the existence of spiritual energy with their spiritual sense no longer need to deliberately look for places where spiritual energy is dense, they will use various means, or inherit,

Even buying formations such as gathering spirit formations to increase the concentration of aura in a certain place is enough to create a place full of aura out of thin air.

What's more, such people, except for those lone cultivators, all have the support of sects, and specially created caves for cultivation, and the aura inside is getting denser and denser.

This is also the reason why the spiritual test reagent will not appear until the day Yang Qing appears.

However, reagents alone are useless, or they are not that useful. After all, the entire Outer Sect site is so big, and there is always a special place where the aura is slightly stronger. For example, some vegetation is particularly lush. A lot of bugs gather, all he can do is to find a limited place that is stronger than his own place of residence, and he can make up for his lack of spirituality a little bit.

The real turning point came after a thunder and lightning. Also affected by the unknown substance of aura, the thunder and lightning in this prehistoric world are also extremely violent. There are not a few people who are killed by lightning every year in this world, and the way they die It is also extremely miserable.

It's not like on the earth, after being struck by lightning, you can still leave you with a whole body. After being struck by lightning, if you are lucky, you can still find some ashes. Unfortunately, it is really scattered yellow dust to make mud Therefore, in thunder and lightning weather, basically no one dared to hang out swaggeringly outside.

The same is true for Yang Qing. He hid in the small room he had just built, and was trembling listening to the thunder, but suddenly found that the color number of the test paper made by the psychic reagent had increased by one level without a sound. grade.

However, after the thunder and lightning ceased, the color of the test paper began to drop rapidly, and did not slow down until it was slightly stronger than before.

What this means, Yang Qing naturally understands very well that thunder and lightning can promote the generation of aura. If there is nothing else he can do, but more than ten years of scientific education has let him know how thunder and lightning are generated, and what to do. How to make a small thunderbolt.

Magnets are not very rare things on the mountain, and silver, a precious metal commonly used in the world, is not of much value here. There is even a silver mine in the outer gate, which is only mined in a small amount every year. It is not like gold at all, because it It is generally rare in the world, and it has a certain value even in the mountains.

But with these two things, Yang Qing can make a big killer, a hand generator.

Of course, the premise of making this thing is that in this world, when the wire cuts the magnetic force line, there will still be a current. Fortunately, after some verification, in terms of basic physics, the influence of spiritual energy is thrown away, and this world is not the same as Blue Star. too much difference.

It is easy to say, but it is not so easy to do. The magnet needs to be shaped and processed into a cylindrical shape suitable for rotary motion, and the roughly purified silver element must be processed into extremely thin wires.

There is good news, of course, that is, silver is softer, easier to stretch, and has a lower melting point. It is also the metal material with the best electrical conductivity in the world. Even if it is changed to another world, its characteristics have not changed. The drawn metal wire can be made very thin, and there is no need to worry about overheating after power on.

After wrapping the pulled silver wire with raw lacquer and fine gauze, it can barely achieve insulation. It can be used to wind the coil, and then make the shell, bearing and center shaft. In order to ensure that the DC current is generated, commutation is also added. Yang Qing not only confirmed that the basic electromagnetic characteristics of this world are not different, but also successfully produced a bulky hand-operated generator after exhausting all the efforts.

Everything else becomes simple. Use two silver wires, connect two carbon rods, shake the generator, and a bright arc will be generated between the carbon rods. You must know that before the invention of electric lights, large Some people use this method to illuminate the square above.

Naturally, this kind of arc is not as powerful as lightning, but it is better than it can be concentrated in a small area. As the arc continues to occur and the smell of ozone begins to fill the room, the concentration of aura shown on the test paper begins to increase. increasing.
