"Ahh

His eyes were suddenly burst by the firelight, and he heard a pig-like scream in his ears, obviously this scream came from He Zhang, a fool.

What is it called?

It's called playing with fire**! Your uncle's!

Although the gunpowder was contained in a bowl and not sealed, it was enough to have a bowl of gunpowder, and the sudden ignition, the deflagration produced by this amount of gunpowder, was close and powerful.

It was simply a large burst of firelight, two or three meters of high-heat flames mixed with thick smoke rising into the sky like a mushroom cloud. In short, Li Yang was two meters away, but he felt that his eyes were about to be blinded by the fierce firelight, and he couldn't see. (PS: Friends who have played with fireworks should have a deep understanding.) ）

Li Yang was really speechless by He Zhang, he had said before that the danger of gunpowder, this guy was so brainless. Well, judging from the screams like killing pigs, this slut must have been injured.

Fortunately, the position where Li Yang was standing was two meters away from the gunpowder, but he was not burned by the flames of the explosion.

Li Yang's face was pale, and he waited tremblingly for a few seconds, and his eyes that were dazzled by the firelight gradually got used to it, and then he hurriedly looked at the position where He Zhang was standing, and his mouth opened into an "O" shape......

I saw a smoky black guy standing there, the whites of the eyes on his blackened face looked very dazzling, his hair had turned into a hairstyle of an explosive head, and there was a trace of smoke on it, he was holding a branch in his hand, and he was still in the posture of starting a fire......

Who else can this fool be besides He Zhang!

Obviously, this guy was also frightened, and stood there, trembling......

Li Yang, who dropped his jaw in shock, rolled his throat for a moment, and then said, "What's that, He Zhang...... You okay? ”

"Woo......"

He Zhangwa cried out suddenly: "My lord, I'm ...... I'm blind...... I can't see anything......"

Li Yang looked at the poor guy and found that his eyes looked normal, so he comforted: "Don't panic yet, close your eyes, and it will be fine after a while." ”

He Zhang nodded, quickly closed his eyes, and after about a minute, he opened his eyes again, and then suddenly the corners of his mouth grinned, revealing a row of snow-white teeth, and said happily: "I can see it, my lord, I can see it, haha!" ”

Seeing his joyful appearance, Li Yang was angry with him.

This time, fortunately, he used a branch to ignite the bowl of gunpowder, and if he had leaned close to ignite it, it would have been strange that his eyes could be saved.

However, gunpowder, a highly dangerous thing, can make He Zhang feel its danger personally, which should be of great help to the awareness of prevention of gunpowder in the future.

As the saying goes, the ignorant are fearless. Only when you are aware of its danger and have a sense of awe and fear can you improve your precautionary mentality.

Sure enough, He Zhang was afraid of gunpowder, and nodded with palpitations: "This gunpowder is so terrible, I was almost scared to death." ”

Li Yang rolled his eyes: "Fortunately, this time it's just a small bowl of gunpowder, if the amount of gunpowder is large, we don't want to live." ”

He Zhang nodded, and couldn't help but become solemn: "My lord, in this way, this thing can't be stored too much at a time, otherwise if you are not careful, all the people in the house will be burned to death." ”

Hearing this, Li Yang was still very satisfied, and said: "Therefore, we must improve safety awareness, and wherever gunpowder is produced, fire will be banned, otherwise the consequences will be absolutely terrifying." ”

Next, Li Yang put forward several requirements for the production and storage of gunpowder.

Workshops for the production of gunpowder had to be relocated to the outskirts of the city alone, away from the crowds.

The workshop for the production of gunpowder must be a small single house, and it cannot be made collectively in a large workshop.

Places where gunpowder is stored and made are prohibited from fire.

The most important thing is that all gunpowder practitioners must carry out safety education, improve safety awareness and prevent risks before they can take up their posts.

He Zhang wrote down Li Yang's requirements one by one, and then asked: "My lord, now that gunpowder has been invented, how are firecrackers made?" ”

"Firecrackers are actually very easy to make!"

Next, Li Yang explained the production method of firecrackers......

In fact, firecrackers are made of hard paper to make a barrel shell, fill the raw materials and light them with a fuse (a paper roll soaked in 30% potassium nitrate solution), which is a firecracker. A number of small firecrackers are connected with fuses, that is, firecrackers, which are the predecessors of modern bombs.

Of course, on the basis of black powder, sucrose can be added as an inflatable agent to increase the loudness.

Fireworks are based on firecrackers, adding colored fireworks, which requires adding an appropriate amount of metal salts to adjust the color, such as strontium salt is red, barium salt is green, sodium salt is yellow, potassium salt is purple, the principle is flame color reaction. And these substances can be extracted from minerals.

After all, the basis of chemical elements is originally derived from a variety of common raw materials.

It's just that, after all, the production of firecrackers and fireworks carries a certain degree of danger, so it can't be like papermaking and printing, as long as the production method and process are explained, you can let go and let the government explore and try. Therefore, Li Yang basically personally handled the next one, directing the people of the general to make a small batch of firecrackers and fireworks.

While making, I didn't forget to explain the principle and safety hazards to them.

In only three days, Li Yang completed 500 firecrackers with 100 firecrackers, 10 firecrackers with 1,000 firecrackers, and 5 firecrackers with 10,000 firecrackers with the help of Jiangzuofu. As well as fifty fireworks, two.

Of course, after Li Yang's on-site guidance, demonstration and explanation, He Zhang and some of the participants in the government already know how to make firecrackers and fireworks. Mass production, apparently, is only a matter of time.

It's just that if you want to make most of the people in Xianyang use firecrackers and fireworks during the New Year, it is impossible, because it is already Chinese New Year's Eve.

Li Yang gave all the 500 firecrackers to the craftsmen who participated in the production of firecrackers, and the 1,000 firecrackers were handed over to He Zhang, so that he could distribute them to Li Si, Cao Shen, Zhang Cang and others. And He Zhang himself was given two firecrackers with 10,000 rings, just enough for Chinese New Year's Eve Chinese New Year's Eve to be hung for dinner, and one for the beginning of the Spring Festival. Of course, Li Yang didn't give him the only two fifty-shot fireworks, because he planned to put these two fireworks on the square outside Xianyang Palace, so that the people of Xianyang City could witness the splendor of the fireworks together.

…………

On Chinese New Year's Eve, every household has hung peach charms, and the gate of the Zhenguo Monarch's Mansion is pasted with a pair of red Spring Festival couplets.

This couplet was written by Li Si, and since the invention of paper, the Qin State has had calligraphy.

It can be said that if this Spring Festival couplet is left in the 21st century, it will definitely be able to change to a big villa in a first-tier city.

As soon as the red Spring Festival couplets were pasted, there were countless pedestrians on the street who stopped to watch and talked about it.

You know, it's a novelty.

Some people can't help but ask, "Why is this poster posted at the gate?" ”

Uncle Wu would roll his eyes as if he was stupid, thinking about this group of ignorant human beings, and then he would say angrily: "Listen to it, my Zhenguo Jun said, the name of this thing is called Spring Festival Couplet, which can ward off evil spirits and eliminate disasters and welcome auspicious blessings." I didn't see the words on it, 'New Year's Yuqing, the festival number Changchun', it is a good word, my town will have Yuqing next year. ”

When everyone heard this, they applauded. Then he began to run to buy red paper, write auspicious words, and paste them on both sides of the door frame.

Perhaps, people are like this, if an ordinary person does this, there may be no one to follow the trend, but Zhen Guojun said this, it must be like this, so there are many followers.

All of a sudden, in just one day, the entire Xianyang City had Spring Festival couplets pasted on the doors of more than half of the people.

In the evening, the Zhenguo Monarch's Mansion prepared a sumptuous Chinese New Year's Eve dinner early.

At this time, other people's houses were already beating drums to ward off evil spirits, and Li Yang moved the 10,000 firecrackers to the door of the mansion, and then drove the pedestrians who were watching the excitement a few meters away, and then spread the long firecrackers on the ground and arranged them into a long line.

The lead was a little, and suddenly it crackled and didn't stop......

10,000 firecrackers, plus the production process of this firecracker is almost the same as the firecrackers of later generations, so the sound is very loud.

The sound of firecrackers was deafening, and all the gongs and drums around it were covered at once.

The firelight appeared, the smoke was filled, the fragrance was fragrant, and the red thick paper wrapped in firecrackers was blown up all over the ground, as if a festive red carpet was laid out at the door of the Zhenguo Monarch's Mansion......

The 10,000-ringing earth red has attracted countless people.

After the 10,000 rings of earth red were released, Wu Bo said proudly: "This is called firecrackers, 10,000 sounds, to drive away evil spirits is not comparable to gongs, burn such firecrackers during the New Year, and the evil disaster will not dare to approach the house for a year." It has a mellow fragrance, a thunderous sound, and red all over the ground, which is really a must-have for New Year's festivals and wedding celebrations! ”

At this moment, everyone has a great attraction to such a good thing as firecrackers, but unfortunately, this kind of thing is not available at the moment.

Of course, at the same time, He Zhang's mansion also burned with ten thousand rings of earth red.

This can make He Zhang very angry.

See, what is this called, this is called ten thousand thunders! It's called Earth Red!

And Li Si, Cao Shen, and Meng Tian, a few ministers of the State Council and the DPRK, also set off firecrackers. However, there were only 1,000 firecrackers in their house, and they finished all at once.

Although the whole family was very excited, they were still very envious when they heard the non-stop sound of firecrackers from the Zhenguo Monarch's Mansion and He Zhang's Mansion.

And those who don't have firecrackers are even more disappointed.

The children in their families asked them why there were no firecrackers in our house.

The parents had to coax: "Next year, our family will also buy it and set off a long firecracker." ”

The child was extremely happy, clapped his palms and laughed, "Yes, yes! There will be firecrackers next year! ”

Of course, at this time, parents will say, "Hurry up and eat, you can see the fireworks after eating." ”

Yes, the notice of fireworks in the square at the entrance of Xianyang Palace has been plastered all over the city. On Chinese New Year's Eve, fireworks will be lit to celebrate the Chinese New Year. At that time, the first emperor and the princes and ministers will watch together, and the whole world will celebrate together.

Of course, although everyone still doesn't know what fireworks are, rumors about fireworks have spread all over the city, saying that the thing will fly into the sky, and then bloom in the sky with incomparably beautiful and brilliant flowers, which are extremely gorgeous.

In short, this incident attracted hundreds of people in Xianyang City.

Everyone waited for Chinese New Year's Eve to finish eating, and then rushed to the square at the gate of Xianyang Palace as soon as possible to gather......
