A great man of the Northern Song Dynasty

The fire-breathing thing originated from fireworks. Gunpowder is at work in all kinds of flying fireworks.

The academy has been thinking about gunpowder and improving its formula.

But now they encountered a bottleneck that Shen An couldn't solve, so those students found other ways to use gunpowder in countless ways. Explosions could be heard in the academy from time to time, or inexplicable flying things. Something that disturbs normal teaching work and makes it difficult to continue.

In the end, Wang Yu took action and suppressed the energetic students who wanted to fly into the sky with a slap, and reached the rule of not making loud noises during class time.

And what Zhao Hao is doing now is what the students are most proud of.

Boo hoo hoo hoo…

Four equally spaced holes were spitting fire downwards, and then the paper bird moved and slowly flew up.

ah!

There were endless exclamations.

Folks in the Song Dynasty only used gunpowder to play with fire. For example, they used gunpowder to create flames or billowing smoke in illusions, using the opportunity to blind people... How does this look like a ninja?

Using gunpowder to make a paper bird fly was almost a miracle in the eyes of everyone at this moment.

Zhao Yunrang looked at the flying paper bird and murmured: "This bird...is this bird really flying?"

Zhao Shu was also shocked, but said calmly: "It's just a kid's thing."

The paper bird gradually flew up to the height of two people. It was probably because of some small mechanism. With a snapping sound, a hole opened in the bird's belly, and then a thin piece of cloth hung down.

A match made in heaven!

The four words are very clear, without any fuss.

There was a burst of exclamation all around.

This gift was a blockbuster.

Ten years later, twenty years later, Bianliang estimates that today's events will still be circulated. Zhao Xu's wedding and Zhao Hao's gift surprised all the guests.

Zhao Yunrang patted his thigh and said, "What a match made in heaven. This word is well written. But how did that bird fly?"

The old guy was obviously stunned by this, but he decided to comment on those four words first.

Those four words are not very good!

Shen An shook his head, Taro tugged on his sleeves, and after Shen An lowered his head, he whispered: "Daddy, it seems better than yours."

This unlucky kid!

Shen An was about to tell him about the greatness of his handwriting, but someone behind him was laughing.

"Uncle Guo is back alive?"

The person who laughed was Cao Yi. Seeing him mention this issue, he couldn't help but retched.

"Brother!"

When Zhao Hao saw his eldest brother, he smiled and handed over his hands, "How about this congratulatory gift?"

There were many gray and black marks on his face, probably from gunpowder spray, and there was even a blister.

The paper bird in the sky was falling crookedly. Zhao Hao wanted to pick it up, but Zhao Xu grabbed him.

Zhao Xu took his hand, spread it out, looked at the blood bubbles on it, nodded vigorously and said: "Okay, this will shock the past and the present."

There was smoke left in the sky, and the paper bird still fell to the ground, looking a little embarrassed.

Zhao Xu took Zhao Hao's hand and said, "Let's go, brother invites you to have a drink."

This is a belated wedding banquet, and we went to Qingning Palace to drink it, so it is the only one today.

The two brothers walked away hand in hand, and everyone watched, gradually smiling.

"It's nice to have a brother like this."

"I thought of my brother. He paid and worked hard to help someone out last time, but I was negligent, so I went back to treat him to a drink."

"Didn't you drink too much? Are you still drinking?"

"There is hot blood in this chest. It won't be fun without drinking."

Zhao Yunrang looked at it with a smile and said: "Brothers and brothers, I am happy to see you. I will tell the beasts at home to follow suit and stop fighting over trivial matters. It is embarrassing."

However, Zhao Shu stopped Shen An who was about to run away.

"How did that paper bird fly?"

Shen An held Taro and felt that it would be troublesome to explain this issue in detail, so he simply said: "In the official family, the gunpowder is kept in one place. For example, if no opening is left for it, and then it is ignited, the gunpowder will be ignited... very Big power.”

The word energy cannot be used yet!

Shen An felt aggrieved.

Zhao Shu was startled, "Power?"

"That... can be understood as strength."

Shen An felt that Zhao Shu was definitely not a good student back then.

"That's it!"

There were many people gathered around, and Zhao Yunrang's eyes widened, "This is a national matter. If anyone leaks it, I will come to greet you personally!"

Damn it!

Old Zhao's threat was too real. If he blocked the door, Zhao Shu would have to send the Imperial City Secretary to raid his house.

So most of the people bowed their hands and said goodbye, not daring to listen anymore.

It's just the itchy look that makes people laugh.

The only one left behind was Zaifu.

"Speak quickly."

Lao Zhao seems to be quite interested in this.

Shen An continued: "The gunpowder is sealed in a thing. After it is ignited and there is no place to vent all the strength, it will..."

He suddenly opened his hands in front of him, "It exploded with a bang. In this northwest expedition, I used gunpowder packets to blow up the city wall. This is why."

"Is that so?"

Han Qi said with emotion: "I only know that gunpowder explodes, but I have never thought of the reason."

"Be more careful."

Old Zhao's eyes were shining, "I'll do whatever I want at home."

Speaking of this, Zhao Shu obviously felt guilty.

Because he became the emperor, his father could only close himself in the prince's palace and rarely go out.

This is all to avoid causing trouble for him. If you think about it carefully, it is all the intention of his parents.

Zhao Shu sighed in his heart and winked at Shen An.

Shen An said: "This matter... you can understand it as... a burst of anger."

He really couldn't find a more vivid metaphor.

Zhao Yunrang understood immediately, "Just say shit, why bother talking about anger."

Too old to practice!

Shen An said helplessly: "Yes. The air is swollen, and it will expand at a moment's notice. If it is tightly packed, it will swell the wrapped things and eventually explode."

"This has something to do with the speed of expansion..."

"It expands instantly, and then the thing surrounding it expands, and finally disintegrates. This is the principle of firecrackers."

"Similarly, the previous bird also wrapped gunpowder in something, but it made a hole. After the gunpowder was ignited, it expanded, but because there was a hole, its strength would escape along the hole... …”

"good!"

Zhao Yunrang patted Shen An on the shoulder and praised: "Well said, even I understand it. When a hole is opened, the force of the gunpowder will rush out of the hole, and the hole will be downwards. That force... is wrong, no, How can you hold the bird up with that strength?"

Everyone was confused.

Shen An smiled and suddenly jumped up.

"Daddy is so awesome!"

Taro clapped her hands and cheered.

Han Qi frowned, "If a person exerts force, he will jump. If the gunpowder keeps pushing downward, it will naturally keep jumping..."

"Yes." Zhao Yunrang glanced at Han Qi, "Mr. Han is smart."

Several prime ministers and ministers have black streaks all over their heads, thinking that according to your statement, are the others stupid donkeys?

Shen An said with a smile: "That's the truth. As for the details, it releases energy instantly, generates high temperature, and releases a large amount of gas..."

This time Han Qi was confused.

"Are these taught in the academy?"

Zhao Shu asked very seriously.

"Yes, but it is all within those students and has not spread."

Shen An knew what he was afraid of, and he was also afraid, "If it spreads, it's actually nothing."

"Nothing?" Han Qi said angrily: "When the Liao people attack the city and seize the territory, they will directly use gunpowder to blow up the city wall. How will the Song Dynasty defend it?"

Shen An smiled and said: "But why did the Song Dynasty need to defend?"

Han Qi was startled and then laughed.

Zeng Gongliang said: "The Song Dynasty is not afraid of the Liao people coming again. They will fight when they come."

Everyone couldn't help but laugh.

yes!

The Song Dynasty is no longer afraid of the Liao people.

If you come, just have a show.

Zhao Yunrang patted Shen An on the shoulder, "That miscellaneous student of yours... I have a grandson in the clan academy, so I can teach him well. If I don't learn anything later, I will just look for you."

Shen An said with a grimace: "It depends on whether you work hard or not."

Zhao Yunrang laughed, and then asked: "What else can this gunpowder be used for?"

"This... is of great use." Shen An said: "For example, it can be used for mining in the future, and it can be used to make more powerful weapons... But these all require the improvement of gunpowder step by step."

"Forging weapons?"

Zhao Shu's eyes lit up, "Tell me."

Shen An felt that there was green light in his eyes, and he looked like a wolf.

Looking at the prime ministers and assistants again, their eyes were even more greedy.

"If you can really make a more powerful weapon, just tell me how many calligraphy and paintings you want later. I will write it specifically for you after I become an official!"

Han Qi held his big belly and was very generous.

Zeng Gongliang said: "Hurry up and tell me that your taro enlightenment will be sent to my home."

Tsk tsk!

Zeng Gongliang personally initiated the enlightenment, which would probably shock the melon-eating masses in Bianliang.

Bao Zheng said nothing, just clenched his fists.

"Gunpowder expands and has strength. What if we get an iron guy and use gunpowder to push it out?"

Shen An looked at them, UU Reading www.uukanshu.net felt that he was bringing out the most terrifying devil in the world.

No matter how many fights were fought in the era of cold weapons, the brutality could not be compared to that of hot weapons.

Hot weapons are powerful tools for opening up new territories!

Zhao Shu looked calm, but Shen An noticed that his legs were moving rhythmically.

It's exciting.

"Shoot out the spear!"

Ouyang Xiu said enthusiastically: "That's much more powerful than the bed crossbow."

Why!

Shen An shook his head and sighed, feeling that he really had nothing to say to these people.

"Hurry up and tell me." Bao Zheng was also itchy.

"A small iron bullet, the size of a child's finger, is pushed out by gunpowder in a tube. The speed is faster than an arrow. If it penetrates the enemy's body..."

Shen An raised his eyebrows: "You don't have to practice hard on archery, just hold it up and light a fire. One pipe per person, a hundred people, a thousand people, ten thousand people...how about it?"

"Bombs are raining down!"

Han Qi sighed, "Your Majesty, please allocate money to go to the academy."

Zeng Gongliang also handed over his hand, "Your Majesty, the academy should be the academy of the Song Dynasty."

Bao Zheng glanced at Shen An and said, "Don't be too cautious!"

Shen An nodded and said seriously: "The academy never considers those knowledge to be the opinions of one family. If it is beneficial to the Song Dynasty, it should be practiced throughout the world."

There are many research projects in the academy, and when they come to fruition one by one, Shen An feels that it will replace Taixue, the so-called museum, and become the most important place in the Song Dynasty.

"How much does it cost?" Zhao Shu was completely moved. "Just talk. If you want to inscribe a plaque, just draw it up."

Tsk tsk!

Everyone had never seen such a generous official, and they couldn't help but laugh.
