Great Tang princess

Chapter 647 Nitrogen Experiment Success
Before Li Yuechen invented gunpowder, during the Chinese New Year, people would throw bamboo into the fire and burn it, which would make a "crackling" sound, so it was called firecrackers.

But the explosion sound when bamboo is burned is really too small, so not every household will do it, and some people are not interested in it.

But ever since Li Yuechen invented gunpowder, invented artillery, and began to use it in warfare, they soon discovered another usage of this thing.

The cannon blasts are loud and the sparks are bright enough to be a good substitute for firecrackers.

In addition, soldiers already like this kind of violent explosion stuff in their bones, so it has become a tradition for the new army in recent years to pull out the artillery and fire it a few times during the Chinese New Year.

Not long after Li Yuechen established the army in Qingdao, they had already done this, and it continued every year after that.

This kind of behavior was also carried out with Li Yuechen's acquiescence, and Liu Huang has also done the same in the past few years.

But it doesn't matter if this kind of thing is said in front of Li Yuechen, but if it is heard by the Second Highness, the consequences will be very serious!
Today's Li Xian is a senior colonel, and his position is the head of the General Logistics Department, managing the financial power in the army.

Extravagance and waste are the most annoying thing on weekdays, and the use of military expenditures is even more strictly controlled.

Even the multi-use case grenade in the cooking class required a detailed report, and he wanted to know the function and whereabouts of each grenade. This behavior of firing a cannon just to hear the sound has seriously touched his bottom line.

Liu Huang turned his head in cold sweat and looked at Li Xian's gaze, and suddenly felt the hairs on his back explode.

He smiled awkwardly: "Second Highness, please allow me to explain this matter..."

Li Xian didn't say a word, just looked at him calmly, without any reaction.

But it was like this, which made Liu Huang secretly complain in his heart, thinking that he must give this staff officer a hard drill afterwards.

Li Yuechen, who noticed that the atmosphere was not right, quickly opened his mouth to smooth things over: "Oh, brother, don't be angry. It's Chinese New Year. If you hit two cannons and hear it, it's considered a celebration..."

While speaking, he kept waving his hands to signal Liu Huang, and let him push the matter on himself.

But what Li Yuechen didn't expect was that she was already prepared to be reprimanded by her second brother, but Li Xian suddenly smiled: "Brother didn't say anything, why is Yuechen so nervous?"

"Hey?"

Now it was Li Yuechen's turn to be dazed: "Aren't you angry about this, brother?"

Li Xian asked back: "Don't you want to be angry for brother?"

"It's not really, it's just..." Li Yuechen was speechless when asked by the second brother for the first time, and didn't know how to answer it for a while.

Wu Zetian on the side couldn't help but smile, their brothers and sisters have been younger sisters and elder brothers since they were young, and now they have finally reversed once.

"Okay, you don't have to be nervous!" Li Xian turned his head and smiled at Liu Huang, and then explained: "A few months ago, the Qianniuwei experiment was successful. If there is no accident, there should be no shortage of nitrate in the future. gone."

"Huh?" Li Yuechen looked puzzled, "Experiment? What kind of experiment?"

"You are so forgetful!" Li Xian couldn't help laughing, "Before going to Yizhou, in Qianniuwei..."

"Ah, I remembered!"

Li Yuechen was taken aback suddenly: "It's about digging a hole to make nitrate, right? What? Was it successful?"

"Well, the current experiment is initially successful, and we can consider digging a large-scale pit to make it like Qingdao Yantian..."

After Li Xian's general explanation, Li Yuechen also understood that what my brother meant was that he wanted to use this method to produce nitrate on a large scale.

Not to mention, this method is really feasible. If it can be made as large as Yantian, the production cost of gunpowder can indeed be reduced a lot in the future.

Because regardless of sulfur or charcoal, the proportion of gunpowder is still relatively small.

As long as the problem of nitric acid can be solved, the cost of gunpowder can only be reduced by half or even more.

No wonder Liu Huang was not so angry when he heard that Liu Huang wanted to fire two cannonballs. Since the price has been lowered, for those who celebrate the Chinese New Year, let’s fire two shots.

So Li Yuechen immediately waved his hand: "Did you hear that? Hurry up and make arrangements, and shoot him a few times!"

Although I don't know what kind of experiment it is, but seeing their conversation, Liu Huang can understand it, and immediately nodded in agreement: "This subordinate understands!"

……

So at midnight, there was a deafening shelling sound outside the barracks.

Even the artillery alone was not enough, and some grenadiers hit the grenade with the prefabricated fragments in the air with a bow and crossbow, causing a series of noises.

In a land of heavy snow, the visibility is actually very high at night because the snow reflects the moonlight.

The next moment, everyone could see that the snow on the mountain in the distance started to flow, and then it turned into a white torrent pouring down the mountain.

"Fuck!"

When Li Yuechen saw that an avalanche was triggered, he quickly told people to stop, but he stopped without calling. After all, the cost of gunpowder was high, so he didn't dare to shoot too much.

On the one hand, it is used as a firecracker, and on the other hand, it also has some meanings to deter foreigners.

"Your Highness, don't worry, we are far away from the mountain, and this avalanche will not reach the barracks!" Liu Huang reassured her.

"It seems that you are very experienced?" Li Yuechen asked.

"That is, it was the same in the first two years, but..."

Speaking of this, Liu Huang was taken aback for a moment, and immediately changed into an attitude of admitting his mistake: "Your Highness, forgive me, your subordinates did not allow it until after confirmation, and it is winter, and no one will go up the mountain at this time..."

In fact, the scale of this avalanche is not very large. After all, the mountains here are not very high, and the avalanche has landed before it has fully formed its scale.

In fact, Li Yuechen once experienced a mountain avalanche, and that is the real horror, like a huge wave on the ocean, rushing down the mountain with a destructive temperament.

Thanks to her good performance at the time, her gliding speed was fast enough, and her reasonable use of the terrain, she was not buried under the avalanche.

Li Yuechen shook his head, pulled his thoughts out of his memories, and then explained the importance of safety to Liu Huang.

Of course, the good thing is that he himself knows the severity, so there is no need to say too much.

……

In the evening, after returning to her room, Wu Zetian let her daughter remove her make-up while smiling and said, "It's fun to come to the border to celebrate the New Year once in a while."

"Really?" Li Yuechen carefully removed the hairpin from his mother's head, "It's really boring to stay in the palace for many years."

Wu Zetian raised his head and thought for a while: "I'm just thinking, what if I let You Lian in the palace learn the singing and dancing here? In the future, I can experience the style of the frontier when I celebrate the New Year in the palace."

Li Yuechen was taken aback, isn't this the prototype of the Spring Festival Gala?

Although the current Spring Festival Gala is still a royal gala, if TV can be developed in the future, the royal gala can really be broadcast nationwide.

So she nodded slightly: "Mother, this idea is good, my child supports it!"

To be honest, Yuren Gongzhong is originally the top song and dance troupe of this era, and it also has the most luxurious resource allocation. It would be good to learn more about programs from different regions and customs.

Wu Zetian nodded slightly: "Since that's the case, let's order it after we go back."

In one sentence from the emperor, the follow-up regulations were completely drawn up.

……

The next day would be the first day of the Lunar New Year. If it was normal, the emperor would have to go to court early to receive congratulations from courtiers and foreign envoys.

As for this year... the emperor at this moment has just woken up not long ago, and is sitting in the room listening to the children talking about last night's artillery.

Compared with firecrackers, the loud cannons obviously make people feel more excited.

Li Xian suggested to his mother excitedly: "Aniang, how about asking Qianniuwei to set up a round of cannons on the city wall during the Lantern Festival?"

After the female relatives came to salute in the morning, they were dragged out by the children to play, so there was only one of them in the room, and Li Xian and the others were relatively relaxed when talking.

Before Wu Zetian could speak, Li Xian turned his head and taught, "This is the army, so it doesn't matter how many times you fire. If it's in the capital of God, what should we do if we cause the people to panic?"

"That……"

Li Yuechen also chimed in on the sidelines: "The key is that Dongdu is too big. If you want the whole city to hear it, you need to shoot a lot of shells. You can empty Qianniuwei's arsenal in one round, and the cost is too high." Already!"

Hearing the two's answers, Li Xian was not disappointed at all. Anyway, he just said that, and he knew it was not realistic.

However, Li Yuechen suddenly laughed: "However... Maybe there will be other surprises in Shangyuan this year."

"Oh? What kind of novelty has Yuechen researched?" Li Dan asked.

"It's not clear whether it will be successful or not." Li Yuechen shook his head, "When I go back, I'll go to Qingdao to see it first. It's okay if it's successful, but if it's not successful, then wait until next year."

These words immediately aroused Li Xian's interest, but no matter how much he begged, Li Yuechen didn't reveal a word anymore, which made him very upset.

But his sister didn't say anything, and he couldn't guess what it was, and he felt uncomfortable all day long.

Of course the others were equally curious, but Li Yuechen didn't say anything, and they didn't ask in detail, anyway, they would know when the time came.

In comparison, the children were happier, taking advantage of the time of Chinese New Year to play enough at the northern border.

Every day is either skiing or snowball fights, or making snowmen, building castles and the like.

……

When eating at noon on the first day of the new year, Li Xian looked at the fish on the plate curiously: "There are still fish here? Isn't the river frozen?"

Li Dan on the side replied: "Brother, didn't you go to the river to have a look? The soldiers are digging the ice to fish."

Li Yuechen also knew about ice fishing, it was a custom of the people living here for many years, so he let them go.

I just told Liu Huang to pay attention to the frequency of fishing, and not to catch too much, so that there will be no fish to catch in the future.

But it's better to do less of this kind of thing in the future, otherwise, if the army is on patrol and slides across the river on a sledge, it will be very troublesome if one accidentally falls down.

……

The family stayed at the northern border until the fifth day of the first lunar month. Thinking that the time was almost up, they planned to leave for the palace.

They had a lot of fun during this period, and Wu Zetian was also in a good mood. On the fifth day of the fifth day, Liu Huang was rewarded with some money and silk.

The soldiers on the northern border also feel that this year is not ordinary.

Not only did he see the emperor Longyan with his own eyes, but most importantly, after having a close contact with him once, he found that the emperor was just a kind-hearted old lady.

Although it is said that the body is full of majesty, it seems that it does not match the imagined appearance.

In fact, it is beneficial for the emperor to appear in front of the soldiers, at least the soldiers will know who they are loyal to.

Li Yuechen was even thinking that in the future, the emperor should go to different military regions for inspection and visits every year when he is free, so that he can get acquainted.

After all, there is no television in this era, and photos are too expensive, so visiting the soldiers in person will not only win the hearts of the people, but also effectively expand the emperor's influence.

After all, in the past, the emperor said that he was supreme, but in fact, as long as he left the palace, no one knew what he looked like, and there was actually a gap between him and the soldiers or ordinary people.

Li Yuechen felt that in the future, he could consider gradually breaking down this barrier in order to increase the public's affection for the royal family.

……

On the sixth day of the first lunar month, just after Yinshi, the huge airship slowly took off under the watchful eyes of the soldiers, gradually rose into the sky, and slowly drifted inland.

Inside the cabin, Li Yuechen asked his mother with a smile, "Would you like to visit Yizhou with your child next year, Ma'am?"

Wu Zetian, who was very satisfied with this trip, smiled slightly, "Well, if the country has nothing to do at that time, it's okay to go and have a look!"

Li Xian who was not far away heard it, turned his head and said, "Yuechen, call me brother."

"That's natural!" Li Yuechen smiled slightly, "It's better for the whole family to go together."

Wei Lian'er and the others also agreed.

Although the emperor's mother-in-law is indeed scary, it has to be said that it is a good thing to be able to travel frequently.

The airship flew all the way to Dongdu in the sky. At dusk, Li Yuechen stood in front of the window and observed the ground environment with a telescope.

At this time, the soldiers in the cockpit also came over and reminded: "Your Highness, we have arrived at the designated location."

"Ah."

Li Yuechen agreed, and then went into the warehouse to get a parachute bag and carried it on his back.

"Yuechen is planning to..."

"It's okay, I'll go to Qingdao first, and I'll be back tonight or tomorrow." Li Yuechen explained while walking towards the cabin door.

Wu Zetian looked curious: "Chen'er has other things to attend to?"

"Don't worry, Auntie, it's just a trivial matter!" Li Yuechen smiled, and then waved his hands, "Sit down firmly!"

While speaking, the hatch has already been opened.

Because there is no pressurized design, it is not too laborious to open the cabin door, but the wind suddenly feels a lot stronger, causing the hair and clothes of everyone in the cabin to fly.

The next moment, Li Yuechen waved his hand at them, and jumped from the sky with a front flip.

The soldiers at the door also quickly closed the hatch.

Li Xian and the others hurriedly ran to the window to look at it. They didn't return to their seats until they found the open parachute.

　It's almost done today, but it's not completely better yet, so there's still only one update, sorry.

　　Thank you [Mercury's Masked Superman] for rewarding 500 starting coins!
