Datang broom star

"This is the fuse. It burns evenly after being ignited. We have tested how long it takes to burn a section for several years. Ten breaths are ten breaths. Those craftsmen guarantee that one more breath or one less breath can be disposed of. The craftsmen of Datang have this ability."

Everyone looked at the thin wires and couldn't help being crazy.

This is the heavy weapon of a great country!

"Then how do you guarantee that the catapult can accurately project the gunpowder package on the top of the city?" Gao Kan knew the difficulty.

"When the old man went to war... At that time, the world was in chaos. Someone got a trebuchet and came out to attack the city. As a result, the thrown stones fell crookedly halfway." Li Ji is a living fossil, and he can be said to be very familiar when talking about these things.

"That's because they don't understand."

Jia Pingan said indifferently: "The base must be stable, otherwise the base will move as soon as the arm swings. How can it be accurate? The shaft frame must be straight and slippery, otherwise the swing arm will be crooked. How can it be accurate..."

Everyone was dumbfounded.

This girl is like listening to a bible.

A craftsman happened to pass by with something in his arms, and he heard the words and said: "Old men, we are craftsmen, but when Mr. Wu Yang bought it, we suddenly realized what he said."

He gave a thumbs up, "Mr. Wuyang's knowledge...no one is not convinced!"

"Damn it! Lord Wuyang even knows the knowledge of craftsmen?" Qibi Heli scratched his head, and a few strands of his already thin hair were scratched down.Annoyed, he clenched his hair tightly in pain, wondering if he wanted to stick it back.

"This is new learning."

Jia Pingan smiled and said, "For Xinxue, the trebuchet is just a simple thing."

"Is this simple?"

Gao Kan felt that Jia Ping'an was a little boastful.

"Of course it's simple." Jia Pingan smiled, "There are mechanics in the new school, and some knowledge of mechanical principles. Catapults are not complicated."

The sophisticated equipment of later generations can be repaired, and this trebuchet is nothing!

Li Ji couldn't help but praise Jia Ping'an's confident attitude: "He is a good learner and dedicated."

Li Jingye happily stepped forward, "Ah, you call me."

Li Ji asked: "Did you learn something new from Wuyang Public School recently?"

Last time Li Ji asked him, but he didn't know what to ask, so he was beaten...

Li Jingye's face collapsed in an instant, "Ah Weng, I...I..."

Li Ji's face darkened, "I'll deal with you after beating Korea."

Qibi Heli asked: "What is that bamboo tube?"

"Drilling Monkey."

"It's filled with gunpowder and quicklime, and uses gunpowder as power to fly up. After it explodes, quicklime fills the air..."

Jia Ping'an smiled very calmly.

"quicklime……"

Li Ji's face changed, "Blind if you put it in your eyes, and your mouth and nose will be burnt if you put it in your mouth..."

"Very poisonous, but the old man likes it."

Gao Kan asked: "Drilling the sky monkey is also a new knowledge?"

Jia Pingan nodded, "It's just a trivial matter."

Gao Kan grabbed him, "Will you accept the grandson in Yeye's family?"

Jia Pingan shook his head firmly, "I don't accept disciples."

Gao Kan said coldly: "If you don't accept Yeye, I will kill you!"

You do it!

Jia Pingan said fearlessly: "Just come."

Li Ji said: "Don't embarrass him. If you want to learn something new, you have to go to mathematics. The only disciple of Duke Wuyang is teaching there."

There is also a second disciple!

The head secretary of the Imperial College knelt down to ask for a teacher.

"That's it."

Gao Kan immediately and kindly smoothed Jia Pingan's clothes that were messed up by him, "Think carefully, I hope to see the day when you become a generation of school masters."

At this time, the gunpowder bag flew out again.

Boom boom boom boom!

The top of the city looked like a thunderbolt.

"Electric light and flint! It's like a thunderbolt!" Pei Xingyan praised.

shhhhhh...

The Diamond Monkey flew up, and the white mist filled the air.

"New Year's Eve!" Jia Pingan couldn't help but miss his previous life.

When firecrackers could be set off in the early years, starting at 24 o'clock on the New Year's Eve, the whole city instantly became a battlefield... The smoke was filled with gunpowder, the sound of explosions was deafening, and all kinds of colorful fireworks...

Suck!

Jia Pingan touched the corner of his mouth.

This journey actually reminded me of the New Year's Eve dinner at Thirty Nights...

The soldiers were also dumbfounded.

"Can you still attack the city like this?"

The top of the city has become a hell, if we attack at this time...

Deng Guan is here.

"British lord, please order me to attack the city."

"At this moment, the Koreans must have deployed an army behind the city."
