?When Yuwen heard that Liu Yang had some secret techniques, he couldn't help but look forward to it. The previous "gold-spotting technique" could make him make money, and he didn't know what the next secret technique would be.

Previously, he showed his true form as a "university monk" and discussed the "Technique of Chemistry" in a long story. His original intention was to destroy Master Liu Yang's "professionality". Unexpectedly, this man seemed to be getting more and more courageous. In order to learn "Technique of Chemistry", he really wanted to present the secret technique at the bottom of his box to exchange for "opportunity".

Not only one "gold-spotting technique" but another secret technique, Yuwen Wen suddenly felt a little guilty at this time. He felt that he had been fooling too much, and that he could not bear it for an uncle to lose everything in exchange for "opportunity".

Just as he was distracted, Liu Yang took out a small cloth bag from somewhere, spread it out and took out something from it: "Please look, Mr. Lang."

Yuwen Wen looked closely and saw that it was a transparent object, about the length and thickness of the thumb, and the two uneven sections seemed to be the remains of something, but the first thing he was concerned about was the material, and he was wondering whether this thing would be glass.

"What is this? Glazed? Crystal?" Yuwen Wen asked.

"This thing is crystal, which is obtained by coincidence of my fate and chance." Liu Yang was quite content with his words.

"How can it be seen as crystal? It may not be true if it is transparent glass."

"I have tried to cut with a knife. This thing is not as fragile as glass, and is as transparent as water. It must be not glass."

Yuwen Wen nodded when he heard this. Because of the Silk Road, glass products of this era are not rare, even glass products are available, such as glass cups, glass bowls, etc. Of course, glass and glass products at this time are still luxury goods.

During the Qi and Liang periods of the Southern Dynasties, foreign merchants came to Jiankang from sea routes and used five-color stones to refine the "Western Region Glass" and sold well in Jiankang City and became a wealthy man. The important source of the Silk Roads of Chang'an, Luoyang and Yecheng also included various glazed products brought by foreign merchants from Western Regions.

In later archaeological discoveries, there were glass cups, glass bowls and other items in tombs of this period, which shows how precious it is. This is why Yuwen Wen's glass/glass jewelry and products can make money.

He picked up the crystal and observed it carefully and found that the cross-section of the thing is similar to a triangle. No matter why the parts of the thing were originally, the thing is now very similar to the prism.

A prism, a glass product with a triangular cross-section, when studying junior high school physics, the refraction of cognitive light will come into contact with this thing. In this era, Yuwen Wen's workshop already has finished products.

The combination of prisms can refract light in a path, which is used as a binocular or a necessary accessory for periscopes. The refraction effect of prisms is very good and can replace mirrors. It also has other uses.

After looking at the prism of this 'coincidental', Yu Wen Wen decided not to say it out loud. After returning it 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 place in the thatched cottage. There were gaps in the wooden walls, and the light of the sunset leaked in through the gap. He placed the crystal in the sunlight, and then said mysteriously: "Please look, Mr. Lang."

‘Isn’t it just to divide the sunlight into seven-color lights…’ Yuwen Wen knew it very well, so he was not surprised to see the sunlight through the crystal turning into seven-color lights. He looked at Liu Yang and was quite disappointed.

‘But with some gold technique... zinc smelting is also good. If the profit of glass mirrors drops sharply, at least they can use brass as gold to subsidize household income.’ Yuwen Wen thought that he would not know when the glass mirror can be made, so he should plan for other ways to make money.

"So that's it, this thing is really interesting." He haha. The boring prism is meaningless. After looking at the room, Yuwen Wen said, "Master, it's getting late, let's pack up and go back to the city."

He followed Liu Yang to this small and dilapidated house, asking the other party to pack up his luggage and move to a designated place to live. In fact, it was to monitor it so that no one with bad intentions would make a cliché and investigate the cause of the big explosion.

"Mr. Lang, I haven't shown my secret skills yet, why are you leaving?"

"Isn't this...uh, haven't started yet?"

"Of course there was no beginning."

After Liu Yang said that, he went to flip through the things, took out a wooden box from the jar, opened it, and put the crystal with a triangle-shaped cross section in it, and then he pissed it off and put the wooden box in the sunlight.

"Please look, gentleman!"

Yuwen Wen leaned over and saw that the sunlight leaked into one end of the wooden box, then passed through the crystal prism, then passed through two suspected glass/glass pieces, and finally projected on the other end of the wooden box.

This end is a little black, and it seems that something is made black. The sunlight casts on it and shows continuous ribbons of red, orange, yellow, green, blue, and purple. There are countless silences on the ribbon.

"This...this..." Yuwen Wen couldn't speak, and this situation made it difficult for him to believe his eyes.

"Mr. Lang, this is just the beginning." Liu Yang was very satisfied with the other party's expression, which shows that the 'opportunity' is getting closer and closer to him. "It's not just the sunshine, please listen to me in detail..."

Liu Yang began to talk about his discovery. By chance, he got this triangle crystal and found that the sunlight turned into seven-color light after passing through the crystal. In surprise, he pointed the crystal at various lights and found that the light emitted was different from the sunlight.

Candlelight, oil lamp, and firewood light are different, which aroused Liu Yang's curiosity. When he was refining alchemy, he found that the flame colors of various fossils burned were different.

Liu Yang had an idea in his mind: Could it be that mercury, iron, copper, gold and silver are different when burned by fire? Then can we judge the composition difference in minerals based on the color of the flame?

So he tried to put a small amount of copper powder, iron powder and tin powder in a gold spoon and put it on the fire to burn it. As expected, the flames were slightly different in color, but when they were mixed together and burned together, they could not distinguish the different colors from the jumping flames.

Given that the sunlight was divided into seven-color light, Liu Yang guessed that it was because the lights of these things were mixed together when they burned, so he had to separate them to see the corresponding color, so he used the triangular crystal to try it out but couldn't.

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

He placed the crystal in a wooden box and placed it near the stove, allowing the burning fire to shine on the crystal through the slit, and then projected on the other end of the wooden box. The fire indeed became a ribbon.

Liu Yang was excited about this discovery. He thought that if he mixed copper powder, iron powder and tin powder and burned it according to this situation, he should be able to distinguish their colors from the light band. To put it bluntly, he could judge whether there was copper, iron, and tin from the burning flames of various mineral powders.

He quickly made a try, widening his eyes to distinguish the colors of copper, iron and tin from the light and shadow ribbons, but he could not see clearly because the color strips in the ribbon were dense and thinner than the hair.

The progress stopped like this. After seven years, Master Liu Yang was about to die. Before his death, he passed on a magic weapon to him. They were two nearly transparent glass cup fragments, similar in size, both thick in the middle and thin at both ends.

Holding a single fragment in your hand to see a very close object has a significant magnification effect. The two fragments are placed in front of you at the same time, moving the distance between them to the appropriate position, and you can see flowers and plants as thin as needles more than tens of steps away.

Liu Yang's master called it the "Thousand Mile Mile Mile" and used it as a treasure. When Liu Yang got the treasure, his first reaction was to use it in his stagnant "study": Since he could "magnify" the flowers and plants and scenery dozens of steps away, he should also be able to magnify the light and shadow ribbons passing through the triangle crystal?

He took out the long-closed crystal and spent a lot of effort to debug it. Finally, he successfully combined the crystal and these two glass pieces in the wooden box, and successfully divided the corresponding colors into the burning flame of the mixture of copper, iron and tin powder.

The ecstatic Liu Yang spent more than ten years using this method to observe the flames of various fossils burning. He had success and failures, but he had summarized his experience and could observe common minerals and distinguish whether there were copper, iron and other components.

"Mr. The brightness of something in the flame indicates that this thing is high in the content, otherwise it is less. If it is not at all, it means that this thing is not in the mineral." Liu Yang said while twisting his beard, looking confident, "This secret technique is the spectrometry."

Yuwen Wen had forgotten to breathe. He looked at the simple equipment and the bull-nosed Taoist priest in front of him. He looked around and looked at the dilapidated thatched hut and the broken jars all over the ground. He could not describe his mood at this moment in words.

What to do, you an alchemy Taoist priest, don’t honestly accept the fate of heavy metal poisoning, and do what to do with optical analysis! What is this called? The alchemy light demon?

He felt a little confused, and he felt that the air in the house was turbid and had difficulty breathing. He walked out of the door, stood in the yard and looked up at the sunset. He was very excited and accidentally discovered that Yuwen Wen almost doubted the world.

This is not a spectroscopy technique, it is clearly a spectroscopy analysis technique!

There is a classification discipline in chemistry called analytical chemistry, among which spectral analysis is the item. There are many categories of spectral analysis, so Yu Wenwen is naturally not clear about it, but the prototype of spectral analysis has been heard a little.

In the seventeenth century, Newton, the 'Apple Heavenly Lord's Lord discovered that prisms could divide sunlight into seven-color light. By the beginning of the nineteenth century, European scientists began to try to use prisms to decompose the flames of metal burning.

After research, they found that the combustion flames of each metal are different. After a series of decompositions, they present a unique color, that is, the spectrum. As long as various spectra can be effectively decomposed, it is possible to distinguish elements through the spectrum.

Through unremitting efforts, scientists successfully realized their original concept using prisms and spectral mirrors composed of lenses. A method of discriminating chemical elements based on spectrum - spectral analysis, was born in the early 18th century.

However, in the Central Plains in the sixth century, in the suburbs of the famous northern city Ye, a bull-nosed Taoist priest who was addicted to alchemy actually touched the threshold for spectrum analysis.

Liu Yang, who is dedicated to elixir, would not know the great prospect of this "splicing technique". Perhaps after taking pills one day, he died of heavy metal poisoning, the technology that had just been sprouted will dissipate with the wind.

Many techniques lost in ancient Central Plains can at least be known to later generations from the unearthed cultural relics. If this alchemist did not encounter the "abnormal" Yuwen Wen, it would only appear silently and then disappear silently.

The gunpowder that the alchemist accidentally discovered by the alchemist promoted the development of human society, but was not beneficial to military and national affairs, and it really couldn't arouse the interests of the rulers.

The same is true for Yuwen Wen. He has to resist his fate, so everything revolves around farming and fighting. Only by farming can you have food, and you can raise soldiers with food. Practice soldiers day and night, and smelting iron on a large scale to build armored weapons. This is the foundation for a stable life. If you can't do this, the rest are all mirrors and water.

Spectral analysis is a high-end technology. Although he is not a major in chemistry, he also has some concepts. Primary spectroscopy analysis can analyze various metal components in minerals and alloys. However, Yu Wenwen thinks it is a waste of time and resources.

If you want to make good iron and steel, you can just find a good source of minerals with the method of filling steel. You can do anything to do with spectral analysis. You don’t have to publish a paper, compete for the Nobel Prize, or invent the ‘Yuwen Temperature Constant’, which harms future high school monks and college monks.

So he never planned to order the "technology tree" in this area. Maybe he would remember to compete for the title of "Supreme of Chemistry" until the overall situation is settled and he has leisure.

The discovery of Taoist Master Liu made him feel very touched: Before modern times, no matter how many geniuses were found in China and abroad, no matter how many discoveries were submerged in the long river of history?

"Mr., what's the opportunity?" Liu Yang asked nervously. He had handed over his two most precious secret techniques in order to learn the mysterious "chemistry".

"The lens material is too turbid, with poor transparency, and failed!"

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

"The lens is irregular in shape, uneven in concave and bump, failure in failure!"

"The worst thing is the slit, the edges are not smooth at all, and there are burrs. Are you making mistakes? Alas, there are burrs!"

Liu Yang opened and closed his mouth, looked at his hard work, and looked at Yuwen Wen. He realized that the "Tian Ji" that he had finally understood seemed nothing in the other party's eyes. It seemed that this person had seen something even more powerful.

"Teach...teach me, teach me...Mr. I want to learn chemistry!!" Liu Yang cried, forgot to call himself "I'm sorry", knelt on both knees, holding his own efforts in one hand, and holding the other's leg with the other hand, begging.
Chapter completed!
