Great Tang princess

Chapter 625
Hearing the person's report, Li Yuechen stood up all of a sudden: "Exploded? Did anyone hurt?"

"It wasn't an explosion." Lai Renhui reported, "It's just that the power has been reduced a lot at once... People from the Engineering Academy, let me tell you, if His Highness is free, it's best to go and watch it in person."

Hearing that there was no explosion accident, Li Yuechen sat down again slowly: "Okay, you go and have a rest too, I will go over to have a look after drinking this cup of tea."

"Yes!" The visitor agreed, saluted and left the office.

Since it wasn't an accident, Li Yuechen was in no hurry. He really drank a cup of tea in the office, and then called two pilots to fly to Weihai together on a hang glider.

The distance between the two places is only more than 200 kilometers, and they can fly there in less than an hour, so Li Yuechen drove a hang glider alone, Xiaodong and Wang Wuqiong were taken by other pilots, and they went there together to see what happened.

Three hang gliders took off from the top of the mountain, and then flew into the sky with the sea breeze.

After finding a suitable airflow between the clouds, he turned around and flew towards Weihai.

Because of the relatively strong sea breeze, there was almost no airflow disappearing along the way, so the speed was much faster. When we arrived in Weihai, it was just after Shen time.

Li Yuechen landed slowly under the guidance of the soldiers on the ground, then handed over the hang glider to them to clean up, and looked around on his own.

A huge flat ground has been opened, presumably it should be the future training ground.It is not very far from the beach, only about 500 meters away. Although the dormitory has not been built yet, from the planning point of view, it is almost certain that it is a sea view room.

There are a few scattered small houses behind the dormitory, which look very dilapidated, and they should not have built them.

The soldiers on the side explained that this was originally a small fishing village with less than 100 people.Because the army wants to use this place, let them make a transfer, build a better village for them, and then let them move there.

If someone is willing to build a new house without charging money, that is naturally good, and everyone in the village has no objection.

Not to mention facing a group of soldiers, who dare not speak up if they have opinions, and obediently cooperate with the arrangement.

Originally, the female relatives of the family hid and dared not go out, but seeing that these soldiers didn't mean to bully them at all, instead they would give them some food from time to time. After a few days, they became familiar with each other up.

Li Longji and other royal children basically helped here during this time. Li Chongfu, who was only ten years old, even got to know a girl of the same age in the village very well, and would bring her some snacks from time to time.

But seeing my aunt coming over today, Li Chongfu ran over after she landed: "Auntie, the children in this village are illiterate, it looks so pitiful, how about letting them study with me?"

"Okay, but why did you do that?" Li Yuechen asked back with a smile.

"This……"

Li Chongfu, who was only ten years old, seemed to be stunned by this question. He just thought that the few children in the village had no new clothes to wear, no conditions to wash every day, and no conditions to study, which felt a little pitiful.

But his current expressive ability still doesn't allow him to accurately express his thoughts.

However, one of the royal education is unity. He couldn't say it himself, so he went to his brothers and sisters to help him answer it. After a while, Li Chongrun and others who were still helping on different construction sites around him surrounded him.

After saluting and saying hello to Li Yuechen, they scrambled to help Li Chongfu answer questions.

Li Longji, who is a little fan, spoke first: "My aunt once said that we, like the royal family, have the important task of safeguarding the country, so we should let the children in this village come to study together!"

"En!" Li Yuechen nodded with a smile, indicating that the answer was correct.

"Should we maintain a kind heart?" Li Xianhui seemed a little unsure, "A gentleman doesn't think that a small kindness is not enough, so he just abandons it..."

"In the final analysis, it is the responsibility of the royal family, right?" Li Longfan, who was relatively late among the children, said, "We can't bully the people like a dandy, we should try our best to improve the living conditions of the people so that they don't have to suffer from hunger and cold... "

"I think……"

Listening to these children's answers, Li Yuechen nodded in satisfaction. At least for now, it seems that the education of these children is relatively successful.

They already have the most basic concept of the responsibility of the royal family in their hearts, and they have embarked on a completely different path from the dudes in the families of the dignitaries and nobles in Dongdu.

She touched their heads one by one, and said with a smile: "Your answers are all right! We and the royal family should not use our talents, knowledge and hard work to chase personal victories. The abilities shaped by the environment are not intended to be superior to those who have not enjoyed the same resources, but to use these abilities flexibly to help them. This will make the country stronger and better!"

……

After another education class, Li Yuechen realized that he didn't come here today for this purpose, he was obviously here to ask about the explosion of gunpowder.

Although no one was injured in an accident, the issue of gunpowder still needs to be taken seriously, otherwise, if an accident does happen one day, it will be quite troublesome.

So after letting the children continue to help everywhere, let people go to the craftsmen to talk about specific things.

Looking up, it was almost dusk. It seemed that today's dinner was going to be eaten here.

After a while, the craftsmen were brought over by Wang Wuqiong and formed a semicircle in front of Li Yuechen.

"Well, tell me, what's wrong with the gunpowder?"

The craftsmen looked at each other, and one of the older ones stood up and said, "Returning to Your Highness, the explosive power of this batch of gunpowder has suddenly become much smaller, and it seems that the charcoal is too large and the combustion is not sufficient. After the explosion, it is still I can see some charcoal the size of a fingernail..."

"Huh? Is it a craft problem?" Li Yuechen frowned.

To make gunpowder, all the raw materials must be pulverized, and charcoal the size of a fingernail is outrageous!
Another craftsman raised his hand suddenly, and said in embarrassment: "Return to Your Highness, the charcoal is a villain. The bamboo tubes are too thick, so I first glued a layer on the inner wall..."

The grenades in this era are made of bamboo tubes, if they are too thick it will indeed reduce the number.

In other words, the craftsman was clever enough to fill the inner wall with charcoal to make the capacity equal to the previous one...

"Then what about the reduction in the power of the explosion?" Li Yuechen asked, "It's just adding an extra layer of charcoal, so it shouldn't reduce the power, right?"

The craftsman in front replied: "According to our observations, the flame was green when it exploded. I think there is copper powder mixed in this batch of raw materials..."

Does copper make explosions less powerful?Li Yuechen frowned and thought about it, but she didn't know much about this, and couldn't find a suitable answer from her own knowledge.

While talking, the craftsman on the opposite side handed her a grenade for her to see.

Li Yuechen reached out to take it, and with a light pinch, the bamboo tube burst into several cracks with a "pop", and then she disassembled the bamboo tube, revealing the appearance inside.

You can see that pieces of charcoal are arranged against the inner wall, and the gunpowder in the middle has become granular. I reached out and squeezed out a handful and twisted it twice with my fingertips, but I didn't see any obvious difference.

The craftsman in front said: "It's not too dark for this matter, why don't you have dinner first, and wait for the sky to darken to see the specific effect."

"Alright." Li Yuechen nodded. She also wanted to know how small the power was. If it affected the lethality, then this batch of raw materials would be useless.

……

The dinner on the construction site is relatively simple, with two dishes, one meat and one vegetarian, as well as white porridge and steamed buns.

After dinner, a group of craftsmen and Li Yuechen came to a small low cliff next to it. It is only a dozen meters above the sea level, and it is a good place for viewing.

A group of children heard that the grenade was going to be thrown, and they all came to watch the excitement. Standing not far behind Li Yuechen, they watched a soldier place a grenade with an extended fuse not far from the cliff, and after lighting the fuse, Run away quickly.

It took about ten seconds for the extended fuse to burn completely, and then there was a "bang" sound, accompanied by a flash of green light, and the grenade exploded, bringing countless charcoal that had not burned out in an instant. An arc was drawn in the middle and landed on the surrounding ground.

Because of the sea breeze, the charcoal became brighter after landing, like fireflies falling on the ground, spreading all over the ground, and then gradually extinguished.

Then everyone walked a few steps forward and came to the place where the explosion just happened. They saw that a pit the size of a human head had been blasted on the ground. Compared with the normal power grenade, the power was directly reduced by more than half.

The craftsmen all looked at Li Yuechen cautiously with guilt after causing trouble.

On the other hand, Li Yuechen frowned slightly. The moment the grenade exploded just now made her think of something else.

"Your Highness, this..."

The craftsman around him looked embarrassed, and seemed to want to ask what should be done next.

However, Li Yuechen smiled slightly, looked up at the sea under the night in front of him, stretched out his right hand and hooked his fingers: "Bring another one here."

The craftsman was a little confused, so he quickly took the grenade and placed it in her hand respectfully.

Then she stretched out her left hand again: "Huozhezi."

Wang Wuqiong quickly took out the fire folder, opened the lid and blew twice, then handed it to her: "Your Highness, be careful."

Li Yuechen took two steps forward, came to the edge of the cliff, and raised his hand to ignite the sinister.

These lead wires are now produced in batches by the Engineering Institute. The burning time is six seconds, and the error will not exceed one second. The degree of completion is very good.

Seeing that she ignited the fuse without throwing it out, the people behind felt a burst of nervousness. Just when they were thinking about whether to make a sound to remind them, Li Yuechen suddenly lifted his left leg straight up, and his knee was completely attached to his chest. On the ground, the two long legs instantly formed a straight line.

Then when the left leg that was raised high fell heavily, the right arm almost became a whip, and he flicked his hand suddenly, only to see a black shadow flash, and the lit grenade in his hand had been thrown into the dark night sky.

How terrifying is Li Yuechen's arm strength?After the grenade was thrown out, there was no trace of it with the naked eye, and it disappeared into the night almost instantly.

However, after less than two seconds, a flower glowing with green light suddenly exploded in the dark night, and it spread out in an irregular state. At the same time, you can see flying out of it. Dots of red light flew around with a short tail.

The ancients present may never have thought that this green flame would have such an effect after it exploded in the air, just like a lotus leaf on the calm water, which can instantly grab people's attention and imprint this scene on the screen. on the retina.

After the green leaves exploded in the air, the radiant red light scattered in all directions embellished the night sky brilliantly.

The little red light that pulls out the light band effect is like a golden chrysanthemum illuminated by the evening sun. The petals are as beautiful and enchanting as the hair of an elf, blooming in the night sky with fleeting beauty.

But the beauty of this moment seems to have left an eternal memory, staying in the minds of everyone present.

The next moment after seeing this light, the sound of the explosion penetrated into the ears, bringing a double mixed shock of vision and hearing.

From Li Yuechen's point of view, the pattern of the fireworks is quite ordinary.But in the eyes of these ancients, this is a magical beauty that has never been seen in their life and could not be imagined before.

Whether it was the artisans present, the soldiers, or a group of royal children, including the maid Xiaodong and the guard Wang Wuqiong, everyone stood silently in place.

Even though the fireworks have disappeared and the night sky has returned to darkness, their spirits seem to be still at that moment just now.

"Clap clap clap..."

Li Yuechen clapped his hands suddenly: "Okay, it's gone, come back to your senses!"

Everyone was drawn back by the clapping, and Li Chongfu immediately said, "Auntie, how about throwing a few more?"

"Don't worry, this thing is just a semi-finished product now!" Li Yuechen smiled, and then waved to the craftsmen, "Let's disassemble all these batches and redo them. In addition, I will get you some more batches of raw materials. There are some people from the Academy of Engineering who specialize in researching this thing. You can make an iron pipe and launch it into the sky. After it explodes in the sky, there will be various patterns..."

Listening to her explanation, the craftsmen's eyes lit up, feeling that this seems to be a very interesting research direction!
"It's already April. If your research speed is fast enough, you may be able to catch up with the Shangyuan Festival next year. When you set it off in front of the saint, not only the Academy of Engineering will reward you, but the palace will also have light on your face, right?"

When the craftsmen heard it, indeed, if it could be blown up in the air according to the predetermined pattern, how beautiful would it be?

"In addition, I will give you some training in the near future to let you know how to change the color of the flame..." Li Yuechen continued, "This thing is also a surprise, if it is made, the Academy of Engineering will give you a third-class merit! "

After hearing what she said, the craftsmen had changed their embarrassing expressions just now, and they all started to look forward to it. The craftsman in front asked, "Then, Your Highness, what is the name of this thing?"

"fireworks!"
