There are many raw materials for modern fireworks, and the raw materials for different colors of fireworks are also different.

Generally speaking, the raw materials generally include KNO3 (potassium nitrate), KClO3 (potassium chlorate), C (carbon powder), S (sulfur powder), Sr(NO3)2] (strontium nitrate), and so on.

Some of these raw materials are easy to obtain, and some are still difficult to obtain, and Li Zexuan can only do his best to get them under the conditions that can be achieved now!

For example, potash salt, it is definitely not realistic for people to find a potash mine now, but you can also get potash from some things around you!

For example, plant ash will do! Because plant ash is the ash after plant burning, it is a mineral element contained in all plants, and almost all plant ash contains it. Among them, the most abundant is potassium, which generally contains 6~12% potassium, of which more than 90% is in the form of carbonate; followed by phosphorus, generally containing 1.5~3%; It also contains calcium, magnesium, silicon, sulfur and trace elements such as iron, manganese, copper, zinc, boron, molybdenum, etc.

In this way, Li Zexuan exhausted his brainpower and used all the raw materials he could use around him, and finally made the first batch of fireworks with multiple colors!

"Brother! Is that good? Can this thing really be as beautiful as a flower? ”

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

This girl has been circling around Li Zexuan since the morning, asking this and that, making Li Zexuan's head big! In the end, Li Zexuan told the little girl that if she was noisy again, today's fireworks would not be able to be made, and Lan'er quieted down.

Seeing that Li Zexuan was obviously going to call it a day at this moment, how could she still bear it after holding it back for so long? immediately ran to Li Zexuan's side to find out!

"Huh! Of course! ”

Li Zexuan clapped his hands and said confidently.

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

Li Zexuan said angrily: "Lan'er, it's still daytime, even if you release it, you won't see anything!" Put it again in the evening! ”

"Huh? Do you have to wait until the evening? ”

Lan'er's little face, which was still very bright, suddenly turned cloudy and overcast, and the little girl's face really changed!

"Huh! Lan'er, don't worry! It's going to be dark for more than an hour, and it won't be long before it gets dark! ”

Han Yuxi walked over and laughed softly.

"Oh well! Sister Yuxi, what do we eat at night? ”

"At night...."

Li Zexuan smiled, this little girl is very close to Han Yu now, and she is almost smooth, he shook his head, and planned to go into the house to soak in the hot spring room in the courtyard and take a rest!

It is said that he dug out a hot spring in this yard, and then he asked people to fence the hot spring, and built a house directly on the hot spring, which was specially used for hot springs in winter, and now he is confined at home, which is a good time to enjoy!

It's just that after the hot spring room was built in the backyard, the space was a little stretched, Li Zexuan planned to expand this courtyard after the New Year, at least to transform it into a large villa courtyard, so that even if a large family lived in, it would not look crowded!

"Alas! Lan'er, this girl is really a little light bulb! ”

Li Zexuan soaked in the hot spring pool alone, thinking angrily.

Anyway, if this girl wasn't there, wouldn't he and Han Yuxi be taking a mandarin duck bath at this time?

.………………………………

Lan'er outside didn't feel the "resentment" from her brother at all, the little girl looked forward to it for a long time, and finally looked forward to it until dark, and tonight's dinner was also eaten half an hour earlier, so as soon as she finished eating, Lan'er pestered Li Zexuan to set off fireworks.

Li Zexuan did not refuse this time, he directly held a large plate of sixty-four fireworks and took it away to the open space in front of the courtyard.

Li Jingmo, Mrs. Li, and the three members of the Ye family all ate here at night, so they naturally came over to watch the fireworks together.

"Huh! I missed the night I came back last night, and tonight is just right! Look at what you guys mean by fireworks! ”

Old Madam Ye said with a smile.

Li Jingmo said a little helplessly: "Xuan'er is a prince, and he tinkers with these useless things at home all day long, and others don't laugh at him when they spread it?" ”

Mrs. Li slapped Li Jingmo's arm and said angrily, "What's the joke?" Xuan'er doesn't want to spend a lively year as an elder for us in Yunshan? Why do you make others laugh? And I heard that King Wei and King Han came to make fireworks in person yesterday, and they did it, why can't Xuan'er do it? ”

Mrs. Ye smiled and said, "Yuzhu is right, this is the New Year, don't take Jingmo seriously!" Outsiders talk about it, but it's not as good as a family reunion to have a good year! ”

"Grandmother is about to cover her ears, my brother is ordering fireworks!"

Lan'er ignored the quarrel between these adults, she tugged on Old Lady Ye's arm at this time, and said excitedly.

"Eh~! Ok, good, good! Grandmother just covered her ears~! ”

Mrs. Ye covered her ears and smiled kindly.

Seeing this, the rest of the people also covered their ears.

"呲呲~!"

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

As soon as the words fell, I heard a slight sonic boom of "bang", and a firework flew into the sky with a red spark, and with a loud "bang", a beautiful flower bloomed in the night sky. The fireworks come in a variety of colors, including red, yellow, blue, green, purple, and pink, and they look beautiful!

"Wow~! It's beautiful! Daddy, Mom! Grandmother! Look! This firework is so beautiful! ”

Lan'er's eyes widened and she shouted.

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

Their eyes widened one by one, in the face of this most beautiful scene in the world, they had even forgotten to breathe at the moment, beautiful, so beautiful that it was "miserable", so beautiful that it was difficult to extricate themselves!

"Bang!"

The fire of the first firework has not yet dissipated, the second firework has already risen into the sky, and there is a loud "bang", a huge flower is proudly blooming, red, orange, yellow, green, blue, purple, everything, purple and red, decorating the night sky beautifully and gracefully, illuminating the earth as if it were day!

"This! This is fireworks? ”

Li Jingmo's mouth was so open that he could stuff a duck egg at the moment, and his breathing became short.

The words that he said before that Li Zexuan was not doing his job can no longer be said at this time, because the beauty of the fireworks is far beyond the scope of his cognition, and in his opinion, such a grand scene is tantamount to a miracle!
