Datang: Li Er, are you teaching me how to do things?

Chapter 160 Winter Solstice Program
The cold wind was blowing, and dark clouds were coiled in the sky, sneering at the earth.

Li Yun carefully collected other gunpowder, and then just poured out a small pile of gunpowder on the ground.

He then took out the firebox, lit a long wooden stick, and touched the gunpowder with the stick.

Because of the cold weather, plus this wooden stick is not a dry firewood stick.

So it was difficult to ignite it all at once. Li Yun burned it for a while, and when there was a spark, he immediately explored it.

Small sparks also have great power. Just as the wooden stick touched the gunpowder, the sparks exploded, and then with a bang, the sparks turned into a pinch of flames.

Then there was another crackling sound, and the flame grew bigger and bigger, turning into a ball of flame.

Li Yun saw it in his eyes and was happy in his heart.

The flame lasted less than five seconds, but there seemed to be some warmth, which made Li Yun feel very comfortable.

But the crackling sound just now was actually because the gunpowder had too many impurities.

This effect is naturally not enough to make fireworks, or bombs or something.

Too many impurities, too dangerous.

Next, Li Yun will not only produce gunpowder, but also refine gunpowder with higher purity that can be safely fired.

He then poured out the powder just now, and found that the crushed powder was not fine enough, and there were still some small gravels.

After thinking about it, he picked out the small gravel, and then continued to grind it.

Not long after, he tested the effect of gunpowder again. Compared with the last time, this time it was much better, and there was no such crackling sound.

But sometimes it burns and burns, and it will suddenly go out.

Li Yun knew that it was because there was a lot of ordinary lime or clay in the gunpowder.

The gunpowder he just made is still not pure enough.

He then continued to exercise, and after about two hours, he condensed another pile of gunpowder.

This time, he absorbed the experience from the previous round, and took the lead in picking out the fine sand and stones inside, and then went to grind them.

Despite the cold weather, Li Yun was sweating all over.

After picking for half an hour, he finally finished picking, and then grinded.

After another half an hour, Li Yun carefully poured out a pile of gunpowder and pulled it into a long thin thread.

He then approached with a torch.

The gunpowder touched the flame and burned instantly.

"Hoo! Hoo! Hoo!"

The flames were cheering, and they were burning with delight.

Li Yun also felt the joy of the flames. This time there were very few impurities, so the flames were unimpeded all the way.

"It's great that it finally worked."

Li Yun then found Fang Yiyu, had a delicious lunch, and flirted with the beauty for a while, and then went on to refining gunpowder.

After about two hours, he refined a pile of gunpowder.

This time he did not test the effect of gunpowder burning.

He found various materials, and then began to make rotating fireworks.

When he was young in his previous life, those small fireworks that could be rotated cost [-] cents each. He liked to play with them very much and would buy many of them.

Now he's going to make the small twirling fireworks first, and then try the big ones.

Previously, the production of gunpowder required calcination and refining, but this time it was completely unnecessary. He followed the production procedure and combined them step by step.

About 5 minutes later, Li Yun made a rotating firework.

He then ignited the rotating fireworks with excitement.

"puff!"

With a crisp sound, the rotating fireworks exploded, followed by a frantic rotation of sparks.

It's like the rotating fireworks played by Li Yun in his previous life, as flexible as a flea.

The sound of Mars barking is also very touching.

Li Yun looked at Mars, as if he had returned to his childhood in his previous life. He laughed, and then made a few rotating fireworks.

……

"Ding! Congratulations to the host for successfully checking in, and reward the host with the essentials for making fireworks that spin into the air."

"Ding! Congratulations to the host for successfully checking in, and reward the host with the essence of making rocket fireworks."

"Ding! Congratulations to the host for successfully punching the card, and reward the host for making the essence of bead-like fireworks."

The outside was pale, so white that it was a bit dazzling, even though Li Yun was lying in the room, he still felt that the outside was very bright.

It's a bright that's white everywhere, with almost no shadows.

He knew it was snowing.

Li Yun immediately put on his clothes, and then rushed out of the palace, and sure enough, he saw a piece of white clothes outside, which was very beautiful.

"Hee hee, come and hit me, come on."

"Miss, don't run away if you have a book."

"Stupid, am I a fool, stand up and let you hit me."

Not far away, there are a few women fighting. At present, the East Palace can have such a privilege, only Taguli and his group.

The passing maids and eunuchs looked at them enviously.

The soldiers were also smiling. The first snow in the second year of Zhenguan came so suddenly, but it was also so warm.

Li Yun said with a smile: "It's snowing today, Gu's mood is very good, pass on Gu's words, the kitchen will add more dishes, everyone will have a chicken leg and a five hundred yuan red envelope tonight."

The eunuch next to him saluted, "Your Highness is benevolent."

After a while, the eunuchs and eunuchs who got the news cheered in unison.

Li Yun then washed up and announced that today is a day off and no morning exercises are required.

After all, it is snowing, and morning exercises in such weather are prone to injury.

Then he thought of Wei Wanyu, and immediately drove to Zheng Guogong's mansion, intending to take Wei Wanyu to enjoy the snow.

He is in a very good mood now. Not only has he successfully refined gunpowder, but he is also becoming more and more proficient in making fireworks. He has arranged for the workshop in the East Palace to start making fireworks.

Of course he concealed how to make gunpowder, which will be a lot of money in the future.

Fang Yiyu saw gunpowder and fireworks, and was so happy from ear to ear, they bought a big house in the west of the city, and this house will be specially used for making fireworks.

As for the sales and types of fireworks, it is not a problem at all.

Because in the past few days, Li Yun has been getting the essentials of making fireworks, all kinds of fireworks.

He already knows how to refine gunpowder, so making fireworks is very easy.

He made faster and faster, easier and easier.

He tried fireworks not only during the day, but also at night, and the results were very good.

Li Yun believes that if the fireworks are released on the night of the winter solstice, they will definitely shock the whole Chang'an.

At that time, the reputation of the fireworks will be a hit, and they will be piled up for sale. He believes that it will last until the Lantern Festival.

Of course, you should also be careful about safety issues. In this regard, Li Yun plans to arrange for someone to explain it, and requires buyers to keep it in mind.

While Li Yun was thinking, the carriage came to Zheng Guogong's mansion, but as soon as Li Yun inquired, Wei Wanyu had already gone out to play with several sister-in-laws.

Also, Wei Wanyu is also a well-known talented woman in Chang'an, even if Li Yun doesn't look for her, she still has many friends.

Li Yun immediately thought of Xiao Mei.

This girl seems to have no friends in Chang'an.

Li Yun thought for a while, and then asked the driver to go to Song Guogong's mansion.
