I am the cook, but I am Li Er's son-in-law

Half a catty of beef is still a heavy burden for Li Lizhi and Li Shu, whose appetites are getting bigger and bigger, and they are both a little full.

After resting for a while, I continued to get up again, discussing the fireworks.

According to Li Lizhi's idea, they confirmed many details.

They didn't even wait until it was dark to go back at night. In the afternoon, the two little girls saw that Zhou Xiaosan hadn't come, so they told Yin Lulu a few words, and then went back happily.

For Li Shimin these few days, it has been a bit of a surprise.

Every day when his two little girls came home, there would be bursts of "bang, bang" sounds, which startled him at first.

I thought it was a disturbance, or something else weird.

The leader carefully touched the imperial garden, only to find out that his two little daughters were trying to make some kind of fireworks. According to their words, they fired gunpowder into the air and then exploded.

Li Shimin didn't stop them.

He even approved a hundred guan for them, and repeatedly told them that this [-] guan can only be used for research and development, and they must not embezzle funds and take it to Tongfu restaurant for dinner.

This disappointed the two little girls.

Li Shimin felt distressed when he saw it, and gave them a monthly increase of ten bills, which made the group of maids heave a sigh of relief.

Following the princess most favored by His Majesty turned out to be the poorest group among all the princesses and prince's maids, and they were helpless.

Now that the money has been raised, they should be able to share more.

It's not dark today.

There was a muffled sound in the imperial garden.

Li Shimin raised his head and looked over: "They came back early today?"

Empress Changsun smiled slightly, and pinched Li Shimin's shoulders: "Your Majesty, you can pamper them, the Royal Garden is already being overwhelmed by them."

"Those two chrysanthemums have already been transplanted." Li Shimin shook his head, "If they can really research something, let alone the imperial garden, they will blow up the Daxing Palace."

There was a bang, and another muffled sound.

Today's explosion was more violent than yesterday's.

Li Shimin paused: "I don't think they will blow up the Daxing Palace."

"Well, probably not."

Empress Changsun asked again: "Your Majesty seems to attach great importance to that thing called fireworks. I heard them say that it is just something for viewing and entertainment."

Li Shimin shook his head: "What I like is not fireworks."

As Empress Changsun said, Li Shimin doesn't care about fireworks, but what he cares about is the technique of firing gunpowder.

Gunpowder is not weak.

But the usage that has been figured out now is to tie it to the arrow and use it to ignite a fire at a distance.

easy to use?
In some specific uses, it is still very useful, but it can't satisfy Li Shimin's ambition, especially after seeing a large amount of gunpowder explode, which can really kill people.
He even hopes that he can bring the effect of this explosion to the battlefield.

Don't say anything else.

If a thing that can shoot gunpowder can be researched, maybe there will be more ideas to use it.

Empress Changsun didn't continue to ask, she just knew that her husband wasn't too spoiled. Her responsibility as a wife was to persuade her husband at certain times.

In the royal garden.

A few maids and eunuchs are watering in a panic, trying to put out a burning osmanthus tree - this is Yang Fei's favorite tree.

Li Lizhi and Li Shu squatted, pointing to the blueprints laid out on the ground.

"Failed again."

"Twice failed."

Li Lizhi's face turned pale, and she sighed. She was very confident in her own ideas.

Li Shu narrowed her eyes and looked at it for a while: "I think there may be a problem with our thinking."

train of thought?

Li Lizhi glanced at Li Shu with some doubts.

"Maybe we shouldn't study, if the gunpowder is lifted into the air at the moment of explosion, maybe we can consider letting the gunpowder explode after it is lifted into the air?"

Li Lizhi gnawed her lower lip: "You mean, let part of the gunpowder burn first, and the gas produced pushes another part of the gunpowder into the air, and then let this part of the gunpowder explode in the air?"

After all, she has studied hard.

Although not as smart as Li Shu, these things are not so dark-eyed.

Li Shu nodded: "Yes!"

"But gunpowder will ignite when it sees a spark. How can we guarantee that the gunpowder will fly and explode?" Li Lizhi asked a very important question.

Li Shu shook her head: "Try with other things first?"

"In short, let's see if this idea can work."

Li Lizhi nodded and agreed.

Two little girls commanded the officials to fill the bamboo tube with gunpowder and a small piece of gold. They stayed away and ignited the gunpowder that spread out.

With a chirp, the gunpowder was ignited, and the fire wire spread away. After a while, the gunpowder in the bamboo tube was also ignited, and with a bang, there was an explosion, and it fell to the ground, with puffs of blue smoke rising from the mouth of the bamboo tube.

The eunuchs at the side breathed a sigh of relief when they saw that nothing was burned this time, and stepped forward alone to check it with ease.

"Your Highness, the gold inside is gone!"

Li Lizhi and Li Shu looked at each other with joy in their eyes.

correct!

This time there was nothing wrong with their train of thought, the thing was indeed shot out, and the next step was to see where the gold flew.

The two calculated a simple parabola, and then urged the eunuchs to find the ingot of gold.

Li Shimin is processing the memorial.

A Qianniu guard gave a report, and after the announcement, he entered the room, holding an ingot of gold in his hand, and his voice was a little excited: "Your Majesty, the heavens are auspicious!"

"The minister was patrolling outside, and suddenly found an ingot of gold falling from the sky and landed in front of the minister. It was actually engraved with the stamp of my Tang imperial family!"

"This is Furui from heaven, which heralds the prosperity of the Tang Dynasty."

Li Shimin waved his hand: "Show me that gold."

Qian Niuwei immediately shut his mouth and presented the gold.

When Li Shimin touched it, it was still a little black, and there were some dark marks on the bottom.

Auspicious?

What he disbelieves the most is the auspicious stuff.

Back then, there was a white magpie making a nest on the locust tree in front of the bedroom. A bunch of people said it was auspicious, but Li Shimin only dropped one sentence: "I often laugh at Emperor Yang of Sui for his auspiciousness, and the auspiciousness is in the virtuous, so what's the point of congratulations!"

So they sent someone to destroy the white magpie's nest.

The white magpie dropped a lump of white feces and flew away cursing.

So even if Qian Niuwei said so, Li Shimin didn't really regard it as auspicious, but thought of the two daughters who were tossing around in the backyard.
