Yuwen Wen heard Liu Yang say that there was still a secret technique, and he couldn't help but look forward to it, the previous 'alchemy' could make him a windfall, and he didn't know what the next secret technique would be. Pen, fun, and www.biquge.info

Previously, in the city, he appeared as a "university monk" in his original form, and talked about the "art of chemistry" at length, originally intending to destroy Liu Yang's "profession", but he never expected that this person seemed to be more and more frustrated, and in order to learn the "art of chemistry", he really wanted to sacrifice the secret art at the bottom of the box in exchange for "chance".

Not only a 'alchemy', but also another secret technique, Yu Wenwen suddenly felt a little guilty at this time, he felt that he had fooled too much, and let an uncle go bankrupt for 'chance', which was quite unbearable.

Just as he was distracted, Liu Yang took out a small cloth bag out of nowhere, spread it out and took out something from it: "Lang Jun, please take a look." ”

Yuwen Wen looked at it, but saw that it was a transparent object, about the length and thickness of a thumb, and the two uneven sections seemed to be the remains of something, but the first thing he focused on was the material, and he wondered if this thing would be glass.

"What is this? Glass? Crystal? Yu Wenwen asked.

"This thing is a crystal, which is obtained by poverty and chance." Liu Yang was quite complacent in his words.

"How can it be crystals? If it is transparent glass, it is not necessarily. ”

"Poor Dao has tried to cut it with a knife, but this thing is not as fragile as glass, and it is as transparent as water, so it is definitely not glass."

Yuwen Wen nodded when he heard this, because of the relationship of the Silk Road, glass products in this era are not uncommon, even glass products are available, such as glasses, glass bowls, etc., of course, glass and glass products at this time are still luxury goods.

During the Qi and Liang dynasties of the Southern Dynasties, there were merchants who came to Jiankang from the sea, and used the five-colored stone to refine the 'Western Regions glaze', which was sold in Jiankang City and then became a huge rich, and Chang'an, Luoyang, Yecheng, these important sources of the Silk Road, also had various glazed products brought by the merchants of the Western Regions.

In the archaeological discoveries of later generations, there are glasses, glass bowls and other items in the tombs of this period, which shows its preciousness, and it is precisely because of this that Yuwenwen's glass/glass jewelry and products can make money.

He picked up the crystal and looked closely, and found that the cross-section of the thing resembled a triangle, and whatever it was originally a part, it was now very similar to a prism.

Prisms, glass products with a triangular cross-section, when learning junior high school physics, cognitive refraction of light will come into contact with this thing, and in this era, Yu Wenwen's workshop already has finished products.

The combination of prisms can refract light according to the path, which is used to make binoculars, or periscopes are necessary accessories, prisms have a good refraction effect, can replace mirrors, and also have other uses.

Looking at this 'coincidence' prism, Yu Wenwen decided not to say anything, and after handing it back to Liu Yang, he pretended to be surprised and asked, "What is the mystery of this thing?" ”

Liu Yang excitedly took the crystal to a certain place in the thatched house, where there was a gap in the wooden wall, and the light of the setting sun leaked in through the gap, he put the crystal in the sun, and then said mysteriously: "Lang Jun, please see." ”

"Isn't it just dividing the sunlight into seven colors of light..."Yu Wenwen knew it, so he was not surprised to see the sunlight through the crystal turn into seven colors of light, he looked at Liu Yang and was quite disappointed.

'But with alchemy... Zinc alchemy is also good, in case the profit of the glass mirror drops sharply, it is better to use brass to pass off as gold to subsidize the family. Yu Wenwen thought, I don't know when the production process of the glass mirror can be kept, so I have to think of some other ways to make money.

"I see, it's really interesting." He snorted, the boring prism was not interesting, looked at the room, Yuwenwen said: "Dao Chief, it's not too early, pack up and go back to the city." ”

He followed Liu Yang to this small dilapidated house, just to ask the other party to pack up and move, and go to a designated place to live, in fact, it was to monitor, so as not to have people with bad intentions to talk about it and find out the cause of the explosion.

"Lang Jun, Poor Dao hasn't shown his secret technique yet, why do you want to leave?"

"Isn't it... Uh, haven't you started yet? ”

"Of course it didn't start."

After Liu Yang finished speaking, he went to rummage through things, took out a wooden box from the jar, opened it and put the crystal with a triangular section into it, and then drummed it again and put the wooden box in the sunlight.

"Lang Jun, please take a look!"

Yu Wenwen leaned over to take a look, only to see sunlight leaking in from one end of the wooden box, then through the crystal prism, then through two pieces of suspected glass/glass, and finally projected at the other end of the wooden box.

This end was a little black, as if it had been blackened by something, and the sunlight cast on it, revealing continuous ribbons of red, orange, yellow, green, cyan, blue, and purple, with countless lines on them.

"It's... This..."Yu Wenwen was speechless, this situation made it difficult for him to believe his eyes.

"Lang Jun, this is just the beginning." Liu Yang was very satisfied with the other party's expression, which showed that the 'opportunity' was getting closer and closer to him, "It's not just the sunshine, please listen to the detailed explanation of the poor road..."

Liu Yang began to talk about his discovery, he got this triangular crystal by chance, and found that the sunlight turned into seven-colored light after passing through the crystal, and he was surprised to point the crystal at all kinds of light, and found that the brilliance revealed was different from the sunlight.

The candlelight, oil light, and firewood light were all different, which aroused Liu Yang's curiosity even more, and he found that the flame color of various minerals when burning was also different during alchemy.

Liu Yang had an idea in his heart: Could it be that mercury, iron, copper, gold, and silver are all different colors when they are burned by fire? Isn't it possible to judge the difference in the composition of minerals based on the color of the flame?

So he tried to put a small amount of copper, iron, and tin powder in a golden spoon and put it on the fire to burn it, and sure enough, the flame color was slightly different, but when it was mixed and burned together, it could not distinguish the different colors from the jumping flames.

In view of the fact that sunlight is divided into seven colors of light, Liu Yang guessed that it was the light of these things when they burned together, so they had to be separated to see the corresponding colors, so he tried the triangular crystal but couldn't try it.

What's the problem? It took Liu Yang five years to solve this problem, he made a wooden box, left a slit, and then in a dark room, he burned copper, iron, and tin powder.

He placed the crystal in a wooden box near the stove, allowing the light of the burning fire to shine through the slit on the crystal, and then cast it on the other end of the box. The flame broke into a ribbon.

Liu Yang was excited about this discovery, and he thought that if he mixed copper, iron, and tin powder and burned them according to this situation, he should be able to distinguish their colors from the light bands, and at worst, he could judge whether there was copper, iron, and tin from the combustion fire of various mineral powders.

He soon tried, widening his eyes to distinguish the colors of copper, iron, and tin from the ribbons of light and shadow, but he could not see clearly, because the ribbons of color were so dense that they could be distinguished thinner than a human hair.

Progress stalled like this, and after seven years, Master Liu Yang was about to die, and before he died, he passed on a magic weapon to him, which were two fragments of almost transparent glass cups, similar in size, thick in the middle and thin at the end.

Holding a single fragment in the hand, so as to see very close objects, there is a significant magnification effect, and two fragments are placed in front of you at the same time, and the distance between them is moved to a suitable position, and you can clearly see the flowers and plants as thin as the tip of a needle dozens of steps away.

Liu Yang's master called it the 'clairvoyant mirror', as a treasure treasure, Liu Yang got the master's treasure, and his first reaction was to use it in his stagnant 'research': since it can 'magnify' the flowers and plants dozens of steps away, then it should also be able to magnify the light and shadow ribbons through the triangular crystal, right?

Taking out the crystal that had been sealed for a long time, he spent a lot of effort to debug it, and finally succeeded in combining the crystal and these two pieces of glass in the wooden box, and successfully separated their corresponding colors in the burning flame of copper, iron, and tin powder mixture.

The ecstatic Liu Yang has spent more than ten years constantly using this method to observe the flames of various minerals when burning, and has succeeded and failed, but has summed up his experience and can observe common minerals and distinguish whether there are copper, iron and other components.

"Lang Jun, the brilliance of something in the flame is bright, it means that the content of this thing is high, and vice versa, if there is no such thing at all, it means that there is no such thing in the mineral." Liu Yang twisted his little beard and said, full of confidence, "This secret technique is the light splitting technique. ”

Yu Wenwen had forgotten to breathe, he looked at the simple equipment, and then looked at the bull-nosed Taoist priest in front of him, looked around, looked at the dilapidated thatched house, the tattered jars and jars all over the ground, and couldn't describe the mood at this time in words.

What to do, you alchemy Taoist, don't honestly accept the fate of heavy metal poisoning, what do you do to play optical analysis! What is it called? Danye Light and Magic?

He felt that his brain was a little messy, and he felt that the air in the house was turbid and difficult to breathe, so he walked out of the door and stood in the courtyard and looked up at the sunset, his heart was excited, and he inadvertently found that Yuwenwen almost doubted the world.

What kind of spectroscopy is this, it's clearly spectral analysis!

There is a classification discipline in chemistry called analytical chemistry, which includes spectral analysis, there are many categories of spectral analysis, Yuwenwen is naturally not clear, but the prototype of spectral analysis has been heard of slightly.

In the 17th century, Newton discovered that a prism could divide sunlight into seven colors, and in the early 19th century, European scientists began to try to use prisms to decompose the light of burning metal.

After research, they found that the combustion light of each metal is different, and after a series of decomposition, it presents a unique color, that is, the spectrum, so as long as the various spectrums can be effectively decomposed, then it is possible to distinguish the elements through the spectrum.

Through unremitting efforts, scientists successfully realized the original idea of using beamsplitters composed of prisms and lenses, and a method for identifying chemical elements according to the spectrum - spectroscopy was born in the early 18th century.

However, in the Central Plains in the sixth century, on the outskirts of the famous northern city of Ye, in a small village, a bull-nosed Taoist priest who was addicted to alchemy actually touched the threshold of spectral analysis.

The great prospect of this 'spectroscopy', Liu Yang, who is dedicated to alchemy, will not know, maybe after taking the pill one day and causing heavy metal poisoning to die, this budding technique will dissipate with the wind.

Many of the techniques that were lost in ancient times in the Central Plains, at least future generations can still know some of them from the unearthed cultural relics, and the spectroscopic technique that this alchemist accidentally discovered, if he did not encounter the 'abnormal' Yuwen Wen, would only appear silently, and then disappear silently.

It was also gunpowder accidentally discovered by alchemists that promoted the development of human society, and the spectroscopy, which was not beneficial to military affairs, really did not arouse the interest of the rulers.

The same is true for Yuwenwen, he wants to rebel against fate, so everything revolves around farming, farming can have food, and if there is food, he can raise soldiers, train soldiers day and night, and make armor and weapons on a large scale.

Spectral analysis, a tall technology, although he is not a chemistry major, but he also has some concepts, primary spectroscopy, can analyze minerals, alloys in all kinds of metal components, but Yu Wenwen feels that this is a waste of time and resources.

If you want to smelt good iron and steel, you just need to find a good mineral source with a steel filling method, and what to do with the effort to engage in spectral analysis, not to publish a paper, to compete for the Nobel Prize, or to invent the 'Yuwen temperature constant', which will harm future generations of high school monks and college monks.

Therefore, he never planned to order the 'tech tree' in this regard, maybe he would not think about it until the overall situation was decided and he had leisure and leisure, and he would compete for the title of 'Chemistry Supreme'.

And this Liu Daochang's discovery made him very emotional: Before modern times, whether at home or abroad, how many genius discoveries were drowned in the long river of history?

"Lang Jun, how is this chance?" Liu Yang asked nervously, he had already handed over his two most precious secret methods, in order to be able to learn the mysterious 'chemistry'.

"The lens material is too turbid, the transparency is poor, and it fails!"

"The prism section is not an equilateral triangle, the refractive index is poor, it fails!"

"The lens is irregularly shaped, uneven, failure within failure!"

"The worst thing is that the slit, the edges are not smooth at all, and there are raw edges, are you mistaken? Hey, there's a raw edge! ”

Liu Yang's mouth closed one by one, looking at his own hard work, and then at Yu Wenwen, he was shocked to realize that the 'heavenly machine' that he was so easy to understand seemed to be nothing in the eyes of the other party, as if he had seen something more powerful.

"Teach... Teach me, teach me... Pimp! I want to study chemistry!! Liu Yang cried and shouted, forgetting to call himself 'Poor Dao', kneeling on his knees, holding his own hard work in one hand and holding the other party's leg in the other hand and begging.

"Uncle, I have two cheats here, one is called junior high school chemistry and the other is junior high school physics, which are not allowed to be taught by those who are not destined... Do you want to learn? (To be continued.) )
