Li Xiaojiu, Li Xiaoshi and others all arrived at Youjian Mall, they didn't expect to celebrate the New Year here today. One of the malls was cleaned up after closing today, and most of the shops have already closed, and the central hall has been reserved.

A total of more than a thousand beggars sat in different places, and when they came here, a person that Li Xiaojiu and they didn't expect appeared on the central stage, looking at His Highness who appeared there, all the former beggars couldn't help but jump up excitedly: "Your Highness." ”

Today, all the beggars who come here are under the age of twelve or thirteen, and the older beggars were directly classified as homeless in the first place.

Equivalent to adults, these children's thoughts are more complex but also more simple, the complex is that they have seen countless human warmth and coldness at a young age, and they know very well how difficult it is to meet someone who treats them as a human being, is willing to raise them, and takes care of them.

Simply as long as someone is willing to be nice to them, they are willing to be nice to that person, and this thinking will be ingrained in them for the rest of their lives.

So when Li Ke came here, most of the beggars couldn't hold back their emotions and jumped up excitedly.

They didn't expect His Highness to actually come to see them.

Li Ke didn't bother them, just smiled and watched them shouting and jumping there excitedly, but soon they all quieted down.

"Didn't you expect me to be here?" Li Ke asked with a smile.

"Yes." All the beggars spoke loudly.

"I deliberately went back to the palace during the day today, and then confessed to my father, saying that I can't accompany them to keep vigil today, and I am here today to celebrate the New Year with you! I know that you used to have a hard time, and every year at the vigil, you never had your family or elders with you. Today I will be your brother, I will be your eldest brother, brother, I will accompany you to celebrate the New Year. Li Ke said with a smile.

"Good!" Li Xiaojiu cried directly, he swore before that he would never cry again, but I don't know why, when His Royal Highness said that he was their brother, Li Xiaojiu couldn't help it, and cried directly.

Many beggars, like Li Xiaojiu, also cried together.

"Okay, okay, we're all strong kids, aren't we? Don't cry, don't cry, you think about how difficult it was for you to come over before, and now it's better, right? Li Ke smiled and reassured.

"Today, I have prepared a lot of good programs for you." Li Ke smiled, he had prepared a lot of troupes today, such as puppet shows, and Li Ke's firm had trained shadow puppets for more than half a year.

Shadow puppetry and puppet theatre are actually somewhat similar, the difference is the use of light, but both can complete a story.

And the stories performed for these children today are actually some stories related to the righteousness of the family and country, such as the story of the Han general Huo Quai's illness and so on.

In addition to these, there are many activities interspersed in the middle, and these activities are not difficult, just take out the activities of Children's Day when you were a child, and it will be a holiday.

What is a small stick to catch pottery bottles there, etc., when they were children, they were all fishing for beer bottles, winning or losing is not important, the important thing is the sense of participation, and these beggars actually have little time to play for a year, Li Ke is not ready to tell them any big truths today.

Just play with them.

Time passed quickly, and when it was about to arrive, Li Ke took all the beggars to the courtyard in the middle of a shopping mall, and all of them stayed around the courtyard, and in the center of the courtyard, cylinders made of iron sheets had been erected there.

And around these cylinders, there are fist-sized, paper-wrapped fireworks that are placed there.

Seeing this shape, many people will recognize it in later generations, this is the kind of fireworks bomb that was popular at the beginning, a round paper tube, and a spherical fireworks bomb, ignite the fuse, and throw the fireworks bomb directly into the paper tube.

I'm sure there are a lot of people who have played this thing.

As for why Li Ke played this kind of fireworks first, it was very simple, this was a new weapon technology he was verifying.

In modern times, the technology of firearms seems to be the lowest, but in fact, in ancient times when the industry was underdeveloped, the technology of firearms was actually very high.

On the contrary, there is one thing that has a much lower technical cost than a firearm...... That's the mortar.

Of course, don't think about modern mortars, Li Ke wants to play is not so high-end, then again, people who have played modern fireworks bombs think about it, don't need to be too high-tech, put modern fireworks bombs on the ancient cavalry battlefield, and put them horizontally against the cavalry rushing towards the enemy, add some broken iron pieces to the fireworks bombs, and don't even use broken iron pieces, as far as the fireworks bombs themselves, do you think they have lethality?

Direct damage may not be high, but incidental damage, hehe.

And now, these cylindrical iron cylinders in the courtyard are one of the key points of Li Ke's verification technology, and it is somewhat difficult to make modern gunpowder, which requires the industrial preparation of three acids and two alkalis to be completely formed, and Datang does not have this condition at present.

Three acids and two alkalis can be made by Li Ke now, but the industrial preparation is not simple, whether it is the Hou's alkali method or others, it is quite difficult at present, but if it is just a simple preparation to play, it is not difficult.

For example, calcium hydroxide is actually hydrated lime. For example, potassium carbonate, although it is not three acids and two alkalis, but potassium carbonate can also be obtained in nature, that is, plant ash, commonly known as grass alkali. This thing collects the ashes of the plant after burning, then dissolves it in water, and then boils it dry, which is a little less efficient, and burns 1 kilogram of wood to get 1 gram of oxaline.

It's far away, it's far away, although the gunpowder in these fireworks is not modern gunpowder, but it is no longer black powder.

For example, finer particles, for example, this time Li Ke secretly added some white sugar.

As for the additives of the flame color reaction, it is simple, find something in nature, or refine it, make whatever color you can make, or simply Schrödinger's color, anyway, he is not a modern firework, and it also requires a shape, which can be colorful.

"I'm going to give you fresh fireworks today! You're the first person in Datang to see them, even my dad hasn't seen them. So, after reading today, you all have to study hard in the future, and strive for one day, you can make bigger and better fireworks, okay?! Li Ke asked loudly with a smile.

"Good!" All the beggars spoke loudly, they all looked at His Highness below with bright eyes, His Highness didn't even show His Majesty, but showed them first, although they didn't know what fireworks were, but His Highness said that it was beautiful, it must be very beautiful.

"It's a little loud for a while, don't be afraid!" Li Ke explained again.

When the voice of the husband beating the guard and notifying the son came from outside, Li Ke waved his hand and said, "Ignition!" ”

The people who came here to set off fireworks today are all soldiers who have been trained and tested by craftsmen, so you don't have to worry about their hands shaking or anything like that.

A total of eight soldiers each took out a round ball from the box next to it, and then lit the lead next to the ball and threw it directly into the iron cylinder.

After a few breaths, the first dull "bang" sounded, and then the invisible ball flew into the sky in an instant.

All the beggars were somewhat frightened, but His Highness had spoken loudly in advance, and they were not afraid.

Soon, a series of "bang" and "bang" sounded one after another, and it seemed that something flew into the dark night sky.

Li Ke had already raised his head, and to be honest, he didn't know what effect this firework could achieve.

Suddenly, with a roar, a cloud of colorful fireworks instantly opened in the dark night sky of Chang'an City!

"Wow!" All the beggars were stunned, the colorful fireworks in their eyes were like miracles, they had never seen such a beautiful thing, it was like the color of the rainbow, but it was released by His Highness.

"Boom" "Boom" Soon, clusters of fireworks began to explode at high altitude!

The brilliant fireworks illuminated the entire Chang'an City, and also attracted the attention of hundreds of people in Chang'an City, as well as the attention of countless patrolling Jin Wuwei.

"Hurry up, boy, what do you see?! Is it a god who has descended to earth! ”

"Xiangrui! Auspicious! It's time to worship the gods! ”

"Even if it's not the thunder male and lightning mother who is thundering, is there a god descending to earth?!"

In all corners of Chang'an City, countless people didn't know what was going on, but the colorful fireworks, in their eyes, were like auspicious, and in an instant, countless people rushed out of the door, and then began to bow in the courtyard in the direction of the fireworks.

In the palace, Li Shimin, who was playing mahjong, was also shocked, he was startled by the shouts of the guards and eunuchs, and when Li Shimin left the palace and looked in that direction, the Imperial Forest Army had rushed to the vicinity of the palace and completely protected the palace.

And the princesses and princes who are also here are also stunned to look at the gorgeous fireworks that continue to explode in the night sky, only Jinyang and the others are not afraid at this time, they just think it is very beautiful, and they shout excitedly there.

When Chang Lin and the others were still talking to Li Shimin about auspiciousness, Jin Yang jumped excitedly and said loudly: "Wow! It's so pretty! I think it must have been made by the third brother! The third brother didn't come to the vigil today, he must have gone to get this thing! ”

Jinyang's words made Li Shimin also think about a little taste, this bastard! It must have been Li Ke's doing! Don't you tell you about such a big thing?!
