There were many raw materials for modern fireworks, and the raw materials for different colors of fireworks were different.
Generally speaking, the raw materials were 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 were easy to get, and some were difficult to get at the moment. Li Zexuan could only try his best to get what he could now!
For example, potassium salt. It was definitely unrealistic to ask someone to find a potassium salt mine, but it was possible to get potassium salt from some of the things around him!
For example, there was some in the ashes of plants! Because the ashes of plants were the ashes after burning, it contained almost all the mineral elements contained in plants. The most abundant element was potassium, which generally contained 6 to 12% potassium, and more than 90% of it was in the form of carbonate. The next was phosphorus, which generally contained 1.5 to 3%. It also contained calcium, magnesium, silicon, sulfur, iron, manganese, copper, zinc, boron, molybdenum, and other trace elements.
Just like that, Li Zexuan exhausted his brain power and used all the available raw materials around him, and finally made the first batch of fireworks with multiple colors!
"Brother! Is it done? Can this thing really be as beautiful as a flower? "
Lan 'er saw Li Zexuan get up and quickly came over to ask.
This girl had been circling around Li Zexuan since morning. One moment she asked this, the next moment she asked that, making Li Zexuan's head hurt from all the noise! In the end, Li Zexuan told the little girl that if she continued to be noisy, he wouldn't be able to make today's fireworks. Only then did Lan 'er quiet down.
At this moment, seeing that Li Zexuan was obviously going to call it a day, how could she bear it after holding it in for so long? She immediately ran to Li Zexuan to find out what was going on!
"Hehe! Of course! "
Li Zexuan clapped his hands and said confidently.
Lan 'er said excitedly, "Then brother, let's see!"
Li Zexuan said unhappily, "Lan 'er, it's still daytime now. Even if I let it go, you won't see anything! I'll let it go at night! "
"Ah? Do we still have to wait until night time? "
Lan-er's face, which was still very bright and beautiful just now, instantly turned gloomy. The little girl's face really changed at will!
"Haha! Lan 'er, don't worry! The sky will turn dark in about two hours. It won't take long! "
Han Yuxi walked over and laughed softly.
"Alright then! Sister Yuxi, what are we eating tonight? "
"At night …"
Li Zexuan smiled. This little girl was quite close to Han Yuxi now. She was almost obedient to her. Others were like repelling each other, but the two of them were like attracting each other!
Shaking his head, Li Zexuan decided to enter the house and head to the hot spring room in the courtyard to soak in the hot spring and rest.
Speaking of which, when he dug out the hot spring in this courtyard, he had people surround the hot spring and built a house directly on the hot spring. It was specially used to soak in the hot spring during winter. Now that he was grounded at home, it was a good time to enjoy it!
However, after building the hot spring room in the backyard, the space was a little tight. Li Zexuan planned to expand this courtyard after the new year. At the very least, he wanted to transform it into a large villa courtyard. This way, even if the whole family moved in, it wouldn't be crowded!
"Sigh! Lan-er, this little girl, is really a little light bulb! "
Li Zexuan thought unhappily as he soaked in the hot spring alone.
Speaking of which, if this little girl wasn't here, wouldn't he and Han Yuxi be soaking in a mandarin duck bath right now?
… … …..
Lan-er, who was outside, didn't feel the slightest bit of "resentment" from her brother. The little girl had been waiting for a long time and finally waited until the sky turned dark. Tonight's dinner was also started an hour earlier. Therefore, as soon as they finished eating, Lan-er pestered Li Zexuan to set off fireworks.
Li Zexuan didn't refuse this time. He carried a large plate of sixty-four fireworks and walked towards the open area in front of the courtyard.
Li Jingmo, Madam Li, and the three members of the Ye Family were all having dinner here. Naturally, they also came to watch the fireworks.
"Hehe! We came back late last night and missed it. Tonight is just right! Let's see what the fireworks are like! "
Old Madam Ye said with a smile.
Li Jingmo said somewhat helplessly, "Xuan 'er is a Marquis. All he does is fiddle with these useless things at home. Won't others laugh at him if word gets out?"
Madam Li slapped Li Jingmo's arm and said angrily, "What's there to laugh at? Isn't Xuan 'er just trying to celebrate the new year for us elders in Yunshan? How is he being laughed at? Also, I heard that the King of Wei and the King of Han came over personally to make the fireworks yesterday. If they can do it, why can't Xuan 'er do it? "
Old Madam Ye laughed and tried to smooth things over. "Yuzhu is right. It's the new year. Jingmo, don't be so serious! No matter what outsiders say, it can't compare to our family celebrating the new year together! "
"Grandmother, quickly cover your ears. Big Brother is going to light the fireworks!"
Lan 'er ignored the quarrel between the adults. She tugged at Old Madam Ye's arm and said excitedly.
"Hey! Okay, okay, okay! Grandmother will cover her ears right now! "
Old Madam Ye covered her ears and smiled kindly.
Seeing this, the rest of the people also covered their ears.
Fizz, fizz ~!
On the other side, Li Zexuan had already lit the fuse of the fireworks with a lighter. Then, he quickly ran over and shouted, "Everyone, cover your ears! The fireworks are going off! "
As soon as he finished speaking, there was a soft boom, and a firework shot into the sky with red sparks. With a loud boom, a beautiful flower bloomed in the night sky. The colors of the fireworks were a riot of colors. There were red, yellow, blue, green, purple, and pink. It looked extremely beautiful!
"Wow! It's so beautiful! Dad, Mom! Grandmother! Look! The fireworks are so beautiful! "
Lan-er's eyes widened as she chirped loudly.
Old Madam Ye, Madam Li, and the others had already looked up and saw the fireworks in the sky!
They all widened their eyes. Faced with this beautiful scene, they even forgot to breathe. It was so beautiful that it was "tragic". It was so beautiful that it was hard to extricate oneself from it!
Boom!
Before the light of the first firework had even dissipated, the second firework had already soared into the sky. With another loud bang, an incomparably huge flower proudly bloomed. Red, orange, yellow, green, blue, indigo, and purple, it was a complete collection of colors. It was a gorgeous purple and brilliant red, decorating the night sky beautifully and gracefully, illuminating the earth as if it was daytime!
"This! This is the fireworks? "
Li Jingmo's mouth was open so wide that a duck egg could be stuffed in it. His breathing also became rapid.
He could no longer say those words about Li Zexuan not doing his job because the beauty of the fireworks was far beyond his scope of understanding. In his opinion, such a magnificent scene was no different from a miracle!
