Mrs. Wang looked at the few family members kneeling on the ground with an iron face: "The prince has always been at home? Throw stones and blindfold your heads! ”

She took a deep breath, "Liu Wei'er is also gone?" So it was Sheng'er who went out with her? This bastard boy, it's dark, and it's so cold, what do you want to do when you run out? ”

Subsequently, the family members set out en masse, shivering and braving the cold wind to go out to find Zheng Sheng.

On the other side, Zheng Sheng finally compromised with Liu Yan'er: "Okay, so be it." You're crouching behind me, where you can hold my hand when you reach out. I remember when I said, 'Cover your ears,' you immediately let go of your hands and cover your ears and look up at the sky. ”

Liu Wei'er nodded, she took two steps back, stretched out her hand to hold Zheng Sheng's hand behind her, and in the night, her little face turned even redder.

Zheng Sheng squatted on the ground two or three steps away from the fireworks, he turned sideways, holding Liu Wei'er with his left hand, holding incense in his right hand, slowly approaching the fuse of the fireworks, Liu Wei'er stretched out his right hand and pulled his left hand, also squatting on the ground, staring curiously at Zheng Sheng's movements.

At this moment, the two members of the manor were searching for this side together, and the two of them were very unlucky, and when they were assigned tasks, they were assigned to the deepest and most remote mountain road.

"Even if the prince runs out to play? Will you go into the mountains blindly? One of them scolded and said, "Yang Zaizi's guy just wants to toss us!" ”

"Alright, don't talk about it, let's go a little further and go back. Anyway, it's impossible for the prince to come here! ”

"That's true!"

Zheng Sheng lit the fuse, he threw away the incense, and shouted, "Cover your ears!" Look at the sky! ”

Liu Wei'er refused to let go of Zheng Sheng's hand, she was still afraid! But she obediently covered her left ear with her other hand.

In an instant, Zheng Sheng stared at her in a daze, and it was too late to correct her mistake.

A heavy "boom-" sound sounded, and Zheng Sheng suddenly felt a loud buzzing sound echoing in his ears. Then, his ears received Liu Wei'er's frightened scream again!

Liu Wei'er was indeed frightened, it was terrible! What a loud voice! It's scary! So, she shouted!

"Look at the sky, look at the sky!" Zheng Sheng shouted at the top of his voice.

When Liu Wei'er heard Zheng Sheng say this, she subconsciously looked up. Then, she saw what she thought was the most beautiful and unforgettable scene of her life.

A bright light flashed in the sky, and with a "whoosh", an incomparably brilliant red, long tail, and dotted chrysanthemum-like object bloomed in the sky above the two of them!

In an instant, the endless elegance is gone with the wind in an instant.

Liu Wei'er thought back to the beautiful chrysanthemum, and was fascinated.

Not far from them, the two family members who were looking for them in this direction also stared blankly at the sky, the fireworks disappeared, and the two looked at each other, "Did you see it?" ”

"Of course I did, oh my God! Is this a miracle? ”

On the other side of the manor, some people also noticed the strange situation in the sky over there, but the fireworks came and went quickly. Everyone was busy looking for someone, thinking that they were dazzled, and hurriedly threw themselves into the ranks of looking for someone.

Zheng Sheng saw the fireworks that he was tired of watching again, and he was amazed in his heart, it was really beautiful!

A cold wind blew, and the two people who were squatting on the ground suddenly came to their senses, Liu Wen'er hurriedly let go of her hand, she still recalled the flower in the sky, "Shizi, is this really made with *?" "She felt incredible, such a dangerous thing, how to make such beautiful fireworks?

"Of course." Zheng Sheng stood up and stomped his stiff foot, "Let's go back!" I'll tell you slowly on the way. ”

"When it comes to fireworks, it's about chemistry." Zheng Sheng started like this.

"Chemistry?" Of course, Liu Wen'er knows this term, which is her most troublesome subject, and it is also recognized by everyone as the most difficult subject.

At the same time, it is also the most controversial academic between Zheng Sheng and Qiu Fuzi.

Qiu Fuzi thinks that Zheng Sheng thinks about the world too complicated, the road is simple, and the heaven and earth are obviously composed of the five elements of gold, wood, water, fire, and earth, not the hundreds of "elements" that Zheng Sheng thinks.

However, Zheng Sheng used some experiments and facts to refute Qiu Fuzi's Five Elements Theory.

However, Zheng Sheng's chemistry class was very difficult, very, very difficult.

"Flame reactions, some metals burn and give off different colors. Do you remember this? ”

Liu Wen'er thought for a while, "Remember." But this thing, you didn't prove it. ”

Zheng Sheng smiled helplessly, can't he prove that it's because there are no conditions? The metal burning conditions were too harsh for him to verify.

But, "Today, didn't I prove it?" The reason why that fireworks are red is that it is the color of metal burning. Zheng Sheng said with a smile.

Liu Wei'er nodded, "There is burning metal in the fireworks that emits red light?" What kind of element is this, make it burn red? ”

Zheng Sheng also looked down and wondered where this metal came from? Do you have any of those exchanges? Is it an element in clay? Also, What metal does the flame color react to red? He doesn't remember!

However, through this incident, he understood that if he wanted to make fireworks, in addition to the things he had thought of before, burning and glowing metal was essential, otherwise he would have to do some artillery battles to play.

"Shizi, I'll help you make fireworks." didn't wait for Zheng Sheng's answer, Liu Wei'er didn't bother with this question, and said in a low voice.

Zheng Sheng nodded, that's right! Didn't he use one of the fireworks just to make her help willingly, "Okay, the housekeepers have smashed the saltpeter into small pieces today, and we will try to grind them all into powder tomorrow." Make * the day after tomorrow! ”

"Is it in such a hurry? It's going to be tiring! Liu Wen'er remembered the previous experience of grinding ore.

"There has been a lot of delay in Shunyang, and it will only be ten days before the first day, we must hurry up!" Zheng Sheng explained to her, "Fireworks, I want to show them to everyone on the first day, what do you think?" ”

"That's good."

"We're going back to Qingzhuling next, and it's probably going to be very busy over there. This small firework is not simple, and in half a month, the two of us don't know if we can make it! ”

Liu Wei'er didn't ask Zheng Sheng about the origin of these three fireworks, she thought of another thing, "So, Shizi, you go to Shunyang to take me, just want me to help you...... Making fireworks? ”

Actually, what she wanted to talk about was grinding stones. But grinding stones is also making fireworks, and by saying that, she feels like she's doing something remarkable, rather than the physical work of grinding stones.

Zheng Sheng was dumbfounded, this little girl is really a clever ghost, did he reveal this kind of information in what he said? Zheng Sheng thought that if she admitted it directly, would she complain that Zheng Sheng would use her as labor again, "No?" Why, I just think you must be too bored in Qingzhuling, so I'll take you out for a spin. Making fireworks is just a little thing I want you to do me a favor. ”

Liu Wei'er heard that Zheng Sheng had started to fool people again, but his lies could fool Qing'er, but he couldn't fool her.

It turns out that the reason he brought himself out was to make fireworks! It's not because of the spring breeze in Shunyang. Liu Wei'er was in a lighter mood.

Thinking of that beautiful firework again, she asked with some hesitation, "Can I make that kind of firework?" It's so beautiful! ”

"Absolutely." Zheng Sheng's tone was affirmative. At this time, he couldn't admit it, and even now he didn't know what the inside of the fireworks was like.

Zheng Sheng took her to touch the dark and slowly bypass the mountain pass along the mountain road, and two torches suddenly appeared in front of her, someone? What are you doing here?

Zheng Sheng motioned for Liu Wei'er to hide behind him and shouted over there, "What person?" ”

The torch over there waved twice, "Is it the voice of the prince?" ”

"The voice of the son? Yes! It's the son! Shizi, Madame let us come out to find you! ”

The voice of the person over there came, and Zheng Sheng's hanging heart relaxed, it turned out that the family in the manor came out to look for him.

Zheng Sheng walked towards them, and the two of them also came up, Zheng Sheng recognized the identities of the two by the light of the fire, "Cai Shuming, Yang Dagou, it's the two of you!" ”

Zheng Sheng knew them because Cai Shuming and Aunt Cai were relatives, and they were also the elder brother of Cai Shuye, the manager of his big kitchen, and there were also people in Yang Dagou's family in his Tiger Guard camp. The two of them were too old and didn't go to Qingzhuling, but they were usually the helpers of Aunt Cai, the cook, so Zheng Sheng got to know them.

"Shizi, it's dark, what are you doing here?" Cai Shuming complained.

Yang Dagou patted him on the head, "Shizi goes out, of course he is doing the right thing, and you can also ask?" ”

Cai Shuming stopped talking.

What Zheng Sheng thought was that even the people in the kitchen came out to look for him, and it seemed that Mrs. Wang was really in a hurry!

So, a group of four hurried back to the manor.

Zheng Sheng sincerely apologized to Mrs. Wang for a while before she let him go.

After having dinner with Mrs. Wang, when he returned to Jing Sixuan, he saw a bunch of things on the ground, saltpeter, sulfur, charcoal, Zheng Sheng checked it and found that charcoal can be used directly, but saltpeter and sulfur ore are still small stones, although the average diameter is less than one centimeter, but it is still too big. Only fine powder should be used.

can only grind slowly tomorrow with Liu Wei'er. Zheng Sheng thought.

Suddenly, he thought of something, "A balance can also turn a whole stone into fine powder, right?" "There is no doubt about that. However, this kind of exchange is just a little more trouble-free, right?

"And you can only exchange one at a time, just saltpeter and sulfur, you need to exchange it twice!" Zheng Sheng vetoed the idea.

However, Zheng Sheng had a new idea. He had always exchanged things from the Jin Kingdom for something new, and he had never tried to exchange things for something new that he had exchanged.

If, for example, he exchanged iron ore for good steel, and then exchanged that iron for muskets, would it work? The exchange ratio of exchanging this iron for muskets can't be a hundred times, right?

If it works, will he be able to get the musket after two exchanges?
