The second lady said with a look of disbelief: "I don't believe it, if you have seen it, you can tell me what this thing is?" ”

Yang Zheng knew in his heart that this was the fireworks of later generations, in fact, they were similar to firecrackers, and their structures contained black powder and medicinal primers. After lighting fireworks, a chemical reaction similar to the one mentioned above triggers an explosion, and most of the energy released during the explosion is converted into light energy to present to our eyes. In the process of making fireworks, some luminescent agents and dynamotics are added to make the fireworks emit a variety of colors.

The luminescent agent is a powder of magnesium or aluminum metal. When these metals burn, they emit an incandescent glow. Chromants are really just metal compounds. Metal compounds contain metal ions. When these metal ions are burned, they emit a unique flame color. Different kinds of metal compounds, when burned, emit different colors of light. But these, even if Yang Zheng said it, the second lady couldn't understand it, and if she couldn't get it right, it would arouse her suspicions, and then she would inevitably have to explain for a while, and then said: "This, of course this is a firecracker, can produce a lot of beautiful fireworks?" “

The second lady heard him vaguely, and was about to say a few words of ridicule, then at this time she heard the sound of "boom", a gorgeous fireworks rushed into the sky from the high cardboard box, the huge sound made everyone exclaim, they all retreated, looked up at the sky, only to see the clear sky exploded a gorgeous fireworks, fireworks, very good-looking, like a gorgeous rainbow, where have everyone seen such gorgeous firecrackers, amazed and applauded, a moment of excitement.

The second lady looked at the gorgeous fireworks and said with envy: "It's so beautiful?" “

"It's not the best time to look at this time, but if it's released at night, the colorful world, then it's good-looking?"

The second lady nodded vigorously and said, "But isn't it, the bad guys will wait a while, let's put one when it's dark, okay?" “

"Fire, this, I'm not very good at this, right? It's very skillful in shooting. Yang Zheng said with a wicked smile.

Although the second lady didn't understand these obscene words, she knew that it was not a good thing to say when she saw his smiling look, so she snorted and ignored him, looking up at the colorful fireworks.

After a burst of fireworks, although some smoke rolls, but the sound is loud enough, gorgeous enough, the sound of the main spark, causing a large number of onlookers, exclamations, more and more festive joy.

Jiang and his entourage were slightly flustered, obviously they didn't expect Duan Yu to have this hand, and while they were surprised, they couldn't help but admire Duan Yu a little, and said with a smile: "This firecracker was developed by the little brother himself?" “

Duan Yu's face flushed, this firecracker was not developed by him himself, but occasionally he saw the owner of the house put a firecracker in a shop, and after the firecracker bombed, it emitted colorful fireworks in the sky, which was very festive.

Duan Yu has always been worried about the fact that the Peng family's annual firecrackers are not as good as the Jiang family, and after seeing this gorgeous firecracker, he was extremely excited, and immediately found this store, wanting to buy the kind of firecracker he saw just now.

When the shopkeeper saw that someone liked this kind of firecracker, he was overjoyed and agreed to sell it to him.

Duan Yu saw that the store was extremely talkative, and saw that this firecracker was different, and after careful inquiry, he learned that this store was originally born in Shangli County, Pingxiang City, and Dongfeng Boundary, Dayao Town, Liuyang City, and his ancestors were made of firecrackers! Since the Tang Dynasty, this craft has been handed down, but many people in the world do not know it.

As soon as Duan Yu heard that his ancestor was a firecracker master, he immediately asked the questions that had been troubled in his chest for many years, and the firecracker master did not hide his secrets, and said them one by one, Duan Yu only then understood that the firecrackers were caused by the moisture of Jiangnan, so they could not explode and dumb fire, and secretly scolded the Jiang family for being despicable and shameless, but he also had to admire that others knew more than himself.

Duan Yu has a gentle temperament, and the firecracker master is also a talkative person, after the two are familiar with each other, Duan Yu learned from the mouth of the firecracker master that his surname is Li Dan, and the firecracker master on his ancestors is named Li Jin, this Li Zhen is talented and intelligent, and he has practiced martial arts with his father, and has been hired as a martial arts teacher in many places. After the death of his parents, he moved to the middle of the Lion-shaped Mountain, where he was accompanied by the herb collector Zhong Suo. One day, the two went up the mountain to collect medicine and hunt, encountered wind and rain, and when they returned home, Zhong Sue couldn't afford to be sick. The villagers say that the mandrill evil spirit is strange (in fact, miasma), and it will be dangerous to hài side. Li Jin was very anxious, and suddenly remembered that his father had said that burning bamboo can drive away evil spirits, that is, he tried it, quite sound, but the explosive power was insufficient, so he boldly drilled a small hole in the bamboo, filled it with nitrate, and detonated it with pine oil seal, and the effect was excellent. The neighbors imitated it, and for a while there was an explosion in the mountains, the fragrance was fragrant, the miasma dissipated, and Zhong Sue recovered. But this kind of bamboo explosion is inconvenient to carry, and unsafe, Li Jin uses paper instead of bamboo, after repeated tests, its sound is like thunder, phosgene. Later, this firecracker was not only used to drive away miasma, but also used for weddings and funerals. Li Zhen for the people to do this business, by all sides of the praise, but due to lack of funds and other reasons, firecracker production failed to develop for a while, passed to Li Ke's generation, the only one left in the family is still running this firecracker business, but he is an honest person, born with no business acumen, although some ancestral craftsmanship, firecrackers are also excellent firecrackers, but first, he didn't expect to make a living from this, second, did not want to make this business bigger, so out of the surrounding people know that he is still operating the ancestral firecrackers accident, But no one knows, if Duan Yu hadn't happened to encounter it, where would he have thought that there were such gorgeous firecrackers in the world.

Originally, Duan Yu didn't think about taking out this firecracker, firstly, he had already mastered the reason why the Peng family's firecrackers could not be exploded and dumb fire, and secondly, it was also opposite to the Jiang family, and he didn't want the relationship between the two families to be too stiff, so this gorgeous colorful firecracker had been placed in the Peng family's shop, if it weren't for the Jiang family being too unreasonable, he would definitely not have made such a move.

Jiang and his entourage looked at the bamboo tube that was more than half a person high, and was both surprised and envious in his heart, but he wanted him to admit that his firecrackers were not as good as others, and he was somewhat reluctant, hehe smiled and said: "Duan Gongzi's firecrackers are good-looking, but it's a pity that they are less lively, after all, they are not as long-lasting as our Jiang family's firecrackers!" ”

Duan Yu seemed to have expected the other party to say this, and said with a sneer: "Fu Bo, give the Jiang shopkeeper a look at our Peng family's firecrackers this year?" ”

Fu Bo had been waiting for this moment for a long time, and shouted at the family behind him: "Brothers, what are you waiting for? Firecrackers? “

It's rare to have a face, naturally you have to work hard for your brother, dozens of Peng family members shouted, turned around and entered the Peng family's shop, not long after Fu Bo led dozens of family members, everyone held the kind of half-person high bamboo tube in their arms, and said to Duan Yu excitedly: "Brother Duan, are we going to set off firecrackers?" “

Duan Yu was rarely stiff, nodded vigorously and said, "Let's let the Jiang shopkeeper's insight and knowledge of our Peng family last last!" “

"How awkward does that sound?" Yang Zheng muttered, pinched the second lady's little hand and said, "Don't blink later, it's beautiful!" The second lady nodded vigorously: "Got it!" ”

Dozens of people put the bamboo tube a few feet away from Duan Yu, Fu Bo held a half-burned incense in his hand and walked over a little nervously, looked at the half-human high bamboo tube, and didn't dare to step forward to light it.

It's no wonder that firecrackers are made of gunpowder after all, although ordinary people think they look good, but they are also a little afraid, for fear that they will explode and hurt themselves, so those who light firecrackers have always been bold people, and Fubo is not a bold person, and the old hand stretched out trembled greatly.

Jiang and his entourage smiled disdainfully: "What's the matter, the Peng family is all gutsless people, and there are no people who light a firecracker?" ”

"Who says no?" Suddenly, a voice came out from the crowd, and everyone followed the voice, only to see a young man with sword eyebrows and starry eyes, and a handsome young man walked out.

"Hua'an—?" Mrs. Peng, the eldest lady shouted in surprise.

"Brother Yang—?" Duan Yu was also overjoyed, he was a scholar after all, and he really didn't have the courage to light these firecrackers, you must know that this test is not only a person's quick eyesight, but also the main boldness.

"Is this also a descendant of the Peng family, so handsome?" There was a murmur in the crowd.

"Dead girl, is it winter now?" A lady scolded in a low voice.

"Didn't Miss also say that he was handsome?" The maid muttered unconvinced.

"How can I have it?" The young lady blushed and glanced at Yang Zheng from the crowd, but the more she looked at it, the more she felt that this family was extremely handsome, and she had long forgotten that the maid on the side was chattering.

Yang Zheng walked out from behind everyone, Jiang and his entourage instinctively narrowed their eyes, looked Yang Zheng up and down, and couldn't help but secretly scream: "I can't imagine that the subordinate who made the Yang family suffer again and again was born so young?" Unbelievable? “

Yang Zheng stepped forward and took the incense from Fu Bo's hand, Fu Bo smiled a little blush, and said, "Let you see the joke?" “

Yang Zheng said: "What did Fu Bo say, although this firecracker seems to be extremely brilliant, it is also the most dangerous, Fu Bo is afraid of it, I am afraid if I don't hide it from Fu Bo, I am also afraid?" “

Fu Bo was stunned for a moment and said, "If you are afraid, why do you want to?" “

Yang Zheng smiled and said: "Because I have a way to prevent people from lighting firecrackers?" ”

"Don't need someone to light firecrackers?" Fu Bo was a little puzzled, but Duan Yu and the others were also slightly flustered.
