Otaku Engineer in Great Tang Dynasty Chapter 1133: The miracle of fireworks!

? There are many raw materials for modern fireworks, and different colors of fireworks have different raw materials.

In general terms, the raw materials generally include KNO3 (potassium nitrate), KClO3 (potassium chlorate), C (carbon powder), S (sulfur powder), Sr(NO3)2] (strontium nitrate), etc.

Some of these ingredients are easy to get, and some are still difficult to get. Li Zexuan can only do his best to get them with the conditions that can be achieved now!

For example, potash, it is definitely unrealistic for people to find a potash mine now, but you can get potash from some things around!

For example, plant ash will do! Because plant ash is the ashes after burning plants, plant ash contains almost all the mineral elements contained in plants. Among them, the most content is potassium, which generally contains 6-12% potassium, of which more than 90% is in the form of carbonate; the second is phosphorus, which generally contains 1.5-3%; it also contains calcium, magnesium, silicon, sulfur and iron , Manganese, copper, zinc, boron, molybdenum and other trace elements.

In this way, Li Zexuan exhausted his brain and used all the available raw materials around him to finally make the first batch of fireworks with multiple colors!

"Brother! Is this all right? Can this thing really be as beautiful as a flower?"

Lan'er saw Li Zexuan getting up, and hurriedly came over and said.

This girl has been spinning around Li Zexuan since the morning, asking this for a while, and asking that for a while, making Li Zexuan a big arguing! In the end, Li Zexuan told the little girl that if there were no more noises, today's fireworks would not be produced, and Lan'er was quiet.

At this moment, seeing Li Zexuan obviously is about to stop work, how can she hold it back after holding it for so long? Immediately ran to Li Zexuan to find out!

"Hehe! Of course!"

Li Zexuan clapped his hands and said confidently.

Lan'er said excitedly: "Then brother, let me take a look!"

Li Zexuan said in a bad mood: "Lan'er, it's still daytime, you can't see anything even if you let it go! Let it go at night!"

"Huh? Have to wait till night?"

Lan'er's very bright face just now, it suddenly turned cloudy, and the little girl's face really changed when she said it changed!

"Hehe! Lan'er, don't worry! It will be dark for more than an hour, and it won’t be long!"

Han Yuxi walked over and laughed softly.

"Well then! Sister Yuxi, what should we eat tonight?"

"At night..."

Li Zexuan smiled, this little girl is very close to Han Yuxi now, and she is almost obedient. He shook his head, and planned to go into the house and go to the hot spring room in the yard to take a break!

It is said that he dug out a hot spring in this yard at the beginning, and then he let people surround the hot spring, and built a house directly on the hot spring, which is specially used for hot springs in winter. Now he is forbidden to stay at home. Good time!

It’s just that after the hot spring room was built in the backyard, the space is a bit stretched. Li Zexuan intends to expand this other courtyard after the beginning of the year. At the very least, it will be transformed into a large villa courtyard, so that even if the whole family are all It won't be crowded when you live in!

"Oh! Lan'er, this girl is really a small light bulb!"

Li Zexuan was immersed in the hot spring pool alone, thinking about it madly.

By the way, if this girl is not there, wouldn't he and Han Yuxi be taking a bath for a mandarin duck?

.………………………………

Lan'er outside did not feel the "resentment" from her brother at all. The little girl looked forward to it, and finally looked forward to dark, and tonight’s dinner was started half an hour earlier, so As soon as he finished eating, Lan Er pestered Li Zexuan to set off fireworks.

Li Zexuan did not refuse this time. He directly walked towards the open area in front of the other courtyard holding a large plate of 64-ring fireworks.

Li Jingmo, Mrs. Li, and the three members of the Ye family all ate here at night, and naturally they followed along to watch the fireworks.

"Hehe! I missed the night I came back last night. Tonight is just right! See what the fireworks you said are like!"

Old lady Ye said with a smile.

Li Jingmo somewhat helplessly said: "Xuan'er Tangtang is a state prince, all day at home fiddles with these useless things, and people don't laugh at him if it spreads out?"

Mrs. Li slapped Li Jingmo's arm, and said in an air: "What's the joke? Isn't Xuan'er wanting to be our elders in Yunshan for a lively year? Why do you make others laugh? And I I heard that Wang Wei and Wang Han came over to make fireworks in person yesterday. They all did it. Why couldn’t Xuan'er do it?"

The old lady Ye smiled and rounded up the field and said: "Yu Zhu is right, this is a big Chinese New Year, Jingmo, don't be serious! Outsiders say or not, they are not as good as a family reunion. Year!"

"Grandma should cover her ears, brother is going to order fireworks!"

Lan'er ignored the quarrel between these adults. At this moment, she pulled the old lady Ye by the arm and said with excitement.

"Eh~! Okay! Grandma, cover her ears~!"

Mrs. Ye covered her ears and smiled kindly.

Seeing this, the others also covered their ears.

"Hey~!"

Li Zexuan on the other side lit the fireworks fuse with a fire fold, and then ran towards this side quickly, and shouted as he ran: "Cover your ears! The fireworks are going to go off~!"

As soon as the voice fell, only a slight sonic boom of "bang" was heard. A firework rushed into the sky with red sparks. With a loud "bang", a beautiful flower bloomed in the night sky. The colors of the fireworks are colorful, red, yellow, blue, green, purple, and pink. They look amazing!

"Wow~! So beautiful! Father, mother! Grandma! Look! The fireworks are so beautiful!"

Lan'er's eyes widened, and she whispered.

Needless to say, Mrs. Ye and Mrs. Li had already looked up and saw the fireworks in the sky!

They opened their eyes one by one~IndoMTL.com~ Faced with this most beautiful sight on earth, they even forgot to breathe at this moment. The beauty, the beauty is so "traumatic", and the beauty is so beautiful!

"Boom!"

The light of the first firework has not dissipated yet, and the second firework has already skyrocketed, with another loud "bang", a huge flower blooming proudly, red orange, yellow, green, blue and purple , Everything is complete, colorful, decorating the night sky beautifully and gracefully, illuminating the earth like day!

"This! Is this fireworks?"

At this moment, Li Jingmo's mouth was open enough to fill a duck egg, and his breathing became quicker.

He said that Li Zexuan was not doing his job properly, but now he can’t say it anymore, because the beauty of fireworks is far beyond his cognition. In his opinion, such a grand scene is no different. Yu miracle!
