Great Tang princess

Chapter 626 New Army Game

With the official establishment of the fireworks project, Li Yuechen asked the engineering academy to select a few apprentices, and returned to the Qingdao Military Region with him to train them on the flame reaction.

But there are not many experiments that can be done so far. It is also known that adding copper to the flame can turn green, sometimes blue, and if you sprinkle salt on the fire, the flame can turn yellow, etc...

However, there are not many colors to choose from, especially Li Yuechen is not a professional in chemistry, she knows a lot of things, but she doesn't know how to separate and extract them in this era.

So tell them directly, division of labor and cooperation, while thinking about how to arrange the fireworks, while pulverizing different ores and adding them to the flame to see the specific reaction, and then record it...

The only thing that can be used at present is this stupid method, but fortunately this is ancient times, even a few simple colors are enough to match each other.

At the same time, Li Yuechen told them that this experiment can only be done in Weihai, not in Qingdao.

Of course, the purpose of doing this is to keep it secret. It is best to show it to my mother directly at that time, which can create a surprising effect.

……

The training here took a few days to finish, and then Li Yuechen issued an order to let Jiang Zheng'an and nearby counties cooperate with each other to get as much ore as possible and send it over. The production is relatively perfect.

As soon as the training was done, Li Chongrun brought a group of royal children to her office, filling up the relatively empty office at once.

"What's the matter?" Li Yuechen raised his head and asked.

"Auntie, let me try the fireworks later." Li Chongrun said with a smile, "If they are set off at the same time at night, it must be very beautiful."

Li Yuechen smiled and shook his head: "This thing, in the future, it's better to set it off only during New Years and festivals, and less on weekdays."

"Why is that?"

"One is the cost issue, and the other is that this product produces a lot of smoke and noise, which is not good for the environment."

As he spoke, he slowly picked up his teacup and took a sip.

The children know about environmental issues. My aunt always said that green water and lush mountains are invaluable assets, so she attaches great importance to environmental protection.

When I was in Dongdu before, I took them to visit a paper mill outside the city, and introduced the waste water discharge system, which cannot be discharged directly into the river, but has to go through many processes for filtration.

So when I heard that it is not good for the environment, I can only dispel such thoughts.

Li Chongrun frowned: "Is that only set off during festivals?"

"The army is close to the forest. If it is not handled well, it will easily cause wildfires. It is best not to let it go." Li Yuechen shook his head.

It's okay to say that a big city like Xiangdongdu, after all, has a lot of people, even if one accidentally ignites, it can be quickly saved.

But the military camp is close to the mountains and forests. Once it is lit, it will be a terrible mountain fire. In this era, there is really no way to deal with such a large-scale disaster.

But it seemed that he saw the disappointment in their eyes, and smiled slightly: "But if you really want to play, you can promote another kind of fireworks in the army in the future."

"Ok?"

The children who were still lost just now heard that there was another substitute, and their eyes suddenly became bright again.

With such a real reaction, Li Yuechen couldn't help recalling a little memory of his childhood, and said with a slight smile, "Why don't you just let you play tonight?"

"Yeah!" The children kept nodding wildly.

This reaction amused Li Yuechen, and he waved his hand to Xiaodong next to him: "Go to the Engineering Academy and ask them to prepare a stove and move it to the training ground, and then take some scraps that are usually used for blacksmithing, and burn them into molten iron after dinner... and then take Two thicker sticks, and..."

Tiehua, which is a kind of artificial fireworks, has this tradition in Shanxi, Hebei, Henan and Shaanxi.

The principle is very simple, that is, hitting or splashing molten iron in mid-air will cause an explosion effect like fireworks, which is extremely dazzling.

The method varies from place to place. In some places, a shed will be set up in the center of the square, covered with willow branches, and the splashed molten iron will hit the willow branches to create a more gorgeous splashing effect.

And some are dry strikes, purely relying on the ingenuity of waving the arms to break up the iron juice splashed in the air, so that it can cause the same effect in the air.

When Li Yuechen was in elementary school, he could always see the iron flower performance during the New Year's festival or the fifteenth day of the first lunar month.

But as I grow up and the development of the times, I basically can't see it after graduating from junior high school.

Perhaps this has something to do with the fact that she lived in a provincial capital city back then, and such performances still exist in many non-provincial capital cities.

It is said to be intangible cultural heritage, but in fact they are all facing the dilemma of being lost.

Suddenly thinking of this today, Li Yuechen felt that it could be used as a way to celebrate the New Year in the army.

First of all, the training ground in the barracks is large and spacious enough, so there is no need to worry about causing a fire.

Similarly, the performers of the Iron Flower are generally shirtless, which can be used as a ritual of exercising courage.

This thing looks scary, but once you master the technique, it's really not that easy to get burned.

Maybe it can be used as a military ceremony and passed down from generation to generation.

……

Soldiers were given orders at dinner time, and assembled on the training ground after dinner.

When they came back from training today, they all saw the stove on the training ground, and there were several people beside them stepping on the bellows to blow into it, making the fire in the stove red and vigorous.

Some curious soldiers went over to ask what it was for, and the answer they got was that they didn't know, it was an order from the princess.

During the meal, Geng Yunqiang also approached curiously and asked what he was planning to do. Li Yuechen told him to eat obediently, and he would naturally know when the time came.

On the contrary, the children couldn't hold back any longer, they devoured their food one by one, as if they planned to finish eating quickly and hurry over to wait.

Although they didn't know exactly what to do, they knew that their aunt would definitely meet their expectations.

Amid everyone's curiosity, Li Yuechen finished his dinner slowly, and was the last one to come to the training ground.

At this time, all the soldiers had already formed a circle on the training ground, quietly looking at the stove in the center of the training ground.

Seeing the princess coming out, both the long-awaited children and the soldiers who had been waiting here all looked at her expectantly.

Several blacksmiths who were in charge of burning the stove also came over: "Your Highness, it has already turned into molten iron!"

"Well, hold on, I'm going to change clothes." Li Yuechen nodded, "By the way, send someone to bring some buckets of water over."

It stands to reason that Iron Flower should be shirtless, but her chest is wrapped with gauze, which is also a risk of burning, so it is better to just wear more.

After going back and changing into a hakama pleat, I came to the square again.

First of all, put a long hair up and pin it on the top of the head, and then put a certain wide hat that has been prepared on the head to prevent the hair from being lit.

Then, under the watchful eyes of everyone, he lifted the bucket directly above his head, and poured the whole bucket of water on his head.

With a "crash", Li Yuechen was drenched from head to toe, as if he had just been fished out of the sea.

Everyone around was stunned, not knowing what she was going to do with her sudden appearance.

Li Yuechen had no choice but to take this method to prevent his clothes and hair from being burned.

After asking the people around to pour water on her two arms again, she raised her hand and wiped her face, took the prepared wooden stick, and came to the stove.

Said to be a wooden stick, it is actually a bit like a table tennis racket, but it is not so big, and it is generally flat.

In his left hand, he held an iron spoon similar to a crucible, but with a larger mouth and a shallower depth, allowing the craftsman to pour molten iron into it.

The blacksmith carefully took a tong to remove a crucible from the stove, poured a little molten iron into the ladle, then Li Yuechen took a few steps back, and with his left hand, the red molten iron in the ladle had been thrown into the air.

It's not high, just look over the top of your head.

However, before it could fall down, Li Yuechen swung his other hand from bottom to top, and the wooden clapper hit the iron juice that had not yet had time to fall.

After the crisp sound of "pop", the next moment, a huge golden chrysanthemum exploded in mid-air, and the dazzling light illuminated the surrounding space for an instant.

Originally, because of the light from the stove, the people around couldn't see Li Yuechen's face clearly, but the moment the light burst, they saw a golden-red cheek.

The light in the flying sky gradually extinguished before it could draw an arc, and after the gorgeous celestial maiden scattered flowers, the rest was darkness again.

But just this one moment has quieted down the surrounding area where there was still some discussion. Everyone focused their eyes on Li Yuechen's hands, waiting for the next surprise.

The blacksmith who was in charge of burning the molten iron was also a little dazed. This scene reminded him of the similar sparks that could erupt when a red-hot iron block was placed on a felt table soaked in water and hit with a hammer.

But why didn't I expect that the splashing of molten iron could form such a dazzling scenery?

At this time, Li Yuechen came back again, stretched out his hand and handed out the spoon in his left hand: "Continue!"

"Yes!"

The blacksmith reacted and quickly poured some molten iron into the crucible.

Li Yuechen took a few steps back quickly, repeated the action just now, lifted the molten iron in the spoon into the air, picked up the wooden stick while it was falling, and hit it on the falling molten iron.

The next moment, a gorgeous and dazzling huge landscape painting unfolded in the air at a height of more than ten meters. The bright and scattered light can feel the instant amazement no matter from which angle you look at it.

If you look carefully, you can see that there are even smaller sparks blooming in the exploding light, like willow branches fluttering in the wind, dense but not crowded.

The sparks scattered in the air formed a bright curtain, and people couldn't help staring at it, wanting to lift the curtain to see what's behind it.

Most of the soldiers opened their eyes wide, staring blankly at the fireworks blooming in the air, as if they were completely immersed in it.

But this stupefaction didn't last long, and then they cheered loudly amidst a loud whistle.

Even Geng Yunqiang, who is usually unsmiling, couldn't help standing up in front of all the soldiers, waving his arms and cheering loudly.

Not to mention the gang of royal children, one by one put their fingers in their mouths from time to time and whistled loudly.

As Li Yuechen continued to spark brilliant sparks, the space under the night sky became flickering, making everyone smile with incredible surprises on their faces.

Flowing fire like gold, the sparks flying all over the sky at this moment made them see the beauty of the world and once again realized the magic of this princess.

However, just as they were getting into it, Li Yuechen stopped after hitting the iron juice in his hand.

Everyone was curious, why did they stop fighting suddenly?
But before they could speak, Li Yuechen said with a smile: "Strike iron flower is a symbol of courage, wait, who wants to try it in person?"

What soldiers need most is courage, Geng Yunqiang immediately stood up: "Your Highness, let me try!"

As he said that, he went to get a bucket to pour water on himself.

However, Li Yuechen stopped him and said: "I am a woman, so I have no choice but to wear clothes. You are a majestic seven-foot man, just go shirtless!"

Geng Yunqiang was stunned for a moment when he heard that he needed to be shirtless. After all, it was molten iron. If it fell and splashed on his body, it would hurt, right?

But this is the end of the story, if you shrink back, do you want to lose face?

So he immediately agreed, and took off his shirt without saying a word, revealing his strong upper body.

Li Yuechen took off the hat on his head and handed it to him: "Put it on, so as not to burn your hair!"

Geng Yunqiang agreed, and put it on obediently, then Li Yuechen picked up the bucket and poured a bucket of water on him: "You have been strengthened, go on! Remember, you have to throw the molten iron over your eyes before raising your hand to hit it!" .”

The drenched Geng Yunqiang agreed, picked up the spoon and wooden stick, and came to the stove.

After asking the blacksmith to pour some molten iron, he threw it into the air according to Professor Li Yuechen's method, and then waved the wooden stick to break it up in the air.

Bright sparks bloomed in the sky again, and the dark sky became bright again.

Countless fireworks fell and hit him, and he felt a little numb for a while.

This is because the spark has cooled down in the process of falling after being hit in the air, so it will not burn the skin.

Of course, this kind of operation requires a strong control of strength to play. If the iron juice is shot too low, or not scattered enough, it cannot be completely cooled during the fall, and it will still cause burns.

It's like some blacksmiths can go directly to the red meringue when forging the iron without wearing gloves. The seemingly simple operation requires not only boldness, but also a strong ability to control oneself.

Geng Yunqiang was just the beginning, after several attempts, Wang Xiaojie couldn't help it anymore, stood up and shouted: "Old man, come and try!"

Li Yuechen reminded with a smile: "Be careful of burns!"

"Don't worry, Your Highness!" Wang Xiaojie also knew that there must be some skill in this, he is not a fool without a brain.

With these two people taking the lead, the other soldiers also shouted to go up and try.

It's obviously not a festival, but the barracks is full of cheerful atmosphere.
