"Lord Wang, the big thing is not good, Wu sent 300,000 troops, and it will be possible to reach Beiyin Fortress in less than half a month, we ......"

"Shh

Qin Yun carefully linked a model.

On one side is a coil made of gold wire, and on the other side is a magnet from a volcano that was discovered earlier.

When the gold wire cuts the coil, the charcoal filament placed in the middle suddenly lights up.

Qin Yun was overjoyed: "It's successful, I'm really a genius!" ”

"By the way, what did you just say?"

"Lord Wang, the Northern Qi army will be able to come to the city in half a month!"

Qin Yun smiled: "It's still early, don't worry!" Order the household department, allocate copper coins to melt and cast copper wire, about such a large thickness, and let people scrape some raw lacquer, remember that it is poisonous, let them pay attention to it! ”

"No!"

Yue Qing on the side came in with a smile: "His Royal Highness King Qin, what are you doing here?" ”

Then he gasped: "You melted all the sisters' gold jewelry?" ”

Qin Yun touched his head embarrassedly: "Isn't this an experiment, gold has the best conductivity, borrow it first and use it, I promise to give you more gold tools in the future." ”

Shen Yue came up from the side: "What's the use?" ”

Han Jiangxue, Bai Wanqing, and Li Daiyu also followed, after Matsumoto Wudou recovered from his injuries, he had already taken a boat back to Fusang to retreat, and before going back, he also threatened Qin Yun that if he dared to hurt Li Daiyu, he would kill his whole family!

Of course, Qin Yun will also listen to it.

Seeing the women coming, Qin Yun began to rotate the coil at a uniform speed, but the carbonized bamboo silk connected by the wire instantly emitted bright light.

This bamboo silk was the simple wick that Qin Yun had prepared, and it was shrouded in a semi-enclosed glass cover.

The women looked at the soft light, but they were fascinated one by one.

"Lord Wang, this is divine light, right?"

Qin Yun said angrily: "This is an electric lamp, the metal wire cutting magnetic field can generate an electric current, and the current is transmitted to this wick through the positive and negative electrodes, so as to emit light." ”

"Of course, this is just a simple prototype of a DC generator, which is very rough, and I use it to verify its credibility!"

The crowd nodded.

"Lord Wang, let me give it a try!"

Han Jiangxue stepped forward, and Qin Yun motioned for her to shake.

"Smack!"

However, Han Jiangxue used too much force, and the fragile bamboo charcoal filament was directly burned out.

Han Jiangxue blamed herself: "Lord Wang, I didn't mean it!" ”

Qin Yun said with a smile: "It's okay, it's just a bamboo core, and when you find tungsten ore in the future, you can use it to make a wick, and you can burn it for a long time." ”

"Lord Wang, where is the tungsten mine, I'll look for it!"

Qin Yun shook his head: "The tungsten mine is buried deep underground, and I want to dig ......"

"No, maybe there is, but don't rush it first, wait for Luban and them to come."

At this time, I thought about it and reported it.

"Lord Wang, Master Lu, they have arrived at the port!"

Qin Yun's eyes lit up: "Really?" Then the king went to meet him. ”

After Qin Yun left, the women followed behind him and whispered.

"Who's going to draw lots today?"

"It's time for Sister Shen Yue to serve the prince!"

Shen Yueqiao blushed: "Is it my turn?" But forget it tonight, the prince's old love is coming. ”

The women giggled, especially Li Daiyu, whose personality changed by fusing memories.

"Shen Yue, tell me about the prince's affairs in the capital!"

Shen Yue paused: "It's hard to say, but the prince is very good at writing poetry!" ”

Bai Wanqing smiled: "I have also received it." ”

Han Jiangxue: "I have it too." ”

Li Daiyu called it unfair: "I also want to find the prince to write poems!" ”

Yue Qing: "Can you understand?" In my opinion, it's better to train me in the forbidden army. ”

"Don't look down on people, I already know fifty Zhongyuan characters."

The women laughed flamboyantly.

"Let's go, pick up the rest of the sisters."

……

On the dock, Qin Yun was looking forward to it!

When he saw that Granny Jiang and Jiang Yingying got off the boat together, they hurriedly greeted them, and behind him, Liu Guanguan and Zhou Meiniang followed out one after another.

"Lord Wang!"

The eyes of the three girls moistened, and Qin Yun poured into his arms in turn.

Granny Jiang glared at Qin Yun angrily: "You guys are deliberately stabbing my old woman's eyes?" ”

"Where is Granny Jiang, oh, this is, Senior Li? Why are you here too! ”

Li Daoling said with a smile: "Senior sister is near Hong Kong Ryukyu, I will follow out for a walk, I heard that you and Matsumoto Takeshi had a fight, how about it?" ”

Qin Yun smiled: "It's okay, this is a disciple of Matsumoto Wudou." ”

"Daiyu, I've seen Senior Li!"

Li Daoling looked at Li Daiyu and said with a smile: "Miss Chiyo, meet again!" ”

"I've seen it, Senior Li!"

"You know?"

"I have a good relationship with her master, King Qin is really powerful, and he can even pick this golden flower."

"Okay, I'm not ashamed!" Granny Jiang spoke, and Li Daoling hurriedly shut up.

Qin Yun was stunned, Wang Menghu's rival is here!

"Mother-in-law, Wang Menghu is injured, so it is inconvenient to come to greet him."

Granny Jiang frowned: "Where is the injury?" Is it heavy or not? ”

"It's not heavy, it's not heavy, why don't you call someone to notify me, stinky boy!"

Everyone looked back and saw that Wang Menghu was on crutches, but he was walking like flying, and there was no trace of injury on his face.

Li Daoling: "Senior sister, this old boy is still pestering you?" ”

"You have to take care of it!"

Granny Jiang greeted Wang Menghu, but she pulled his ears for a while.

Li Daoling smiled silently, while Qin Yun ignored the love and love between this group of old North Noses, he turned his head and greeted Lu Ban, Zhutieling, and a group of craftsmen warmly.

"Welcome!"

"The prince is too polite, this time the prince called us here, but there is a big move?"

Qin Yun said: "It's windy here, please come later!" ”

……

In the Beiyin Mountain Palace, everyone gathered together, and the cheers continued.

Lu Ban opened his mouth and said, "Lord Wang, is the hot air balloon still enough?" ”

Qin Yun: "I tried this thing, the stability is too poor, the platform is too small, it is not easy to deploy, and it cannot carry heavy weapons." So, it was necessary to develop something new. ”

"Here's the drawing, look at it!"

Lu Ban took it and looked at it, and then handed it to Cast Iron Ridge.

"Lord Wang, this design and construction is not difficult, it is nothing more than installing a small steam engine and it is over, but the question is how to fly this airship? According to the "Treatise on Air" written by the prince, when the force of an object is less than that of a heavy object, it cannot float in the air. ”

Qin Yun said: "So, we need something lighter than air, and I already have a way to prepare this thing, provided that the problem of electricity is solved." ”

"However, this is not a problem, this is the design of the generator, you two take a look, this is the experimental device."

Lu Ban and Cast Iron Ridge glanced at each other, but they devoted themselves to the study with great interest.

"Lord Wang, is it electricity that makes the bamboo core shine?"

Qin Yun said: "That's right, it's electricity, and we can use electricity to electrolyze seawater, in addition to hydrogen, we can also obtain other important chemical products." However, hydrogen is flammable and explosive and needs to be stored and disposed of properly. ”

"Don't worry, we have improved the hydraulic tank. This time, a bigger one can be made. ”

"It's just that the current can't keep people shaking, right?"

Qin Yun smiled: "How is that possible?" ”

"Add a propeller shaft and a steam engine, what do you two say?"

"Haha, the prince is clever!"

Qin Yun: "It's not that I'm smart, but that's the case!" By the way, what is the situation in Qiongzhou? ”

"Everything is fine, the military output has increased significantly, the shipyard is also running in an orderly manner, and now there is another battleship out of the factory, according to the prince, this battleship has a displacement of 1,600 tons!"

Qin Yun was overjoyed: "Okay, very good, finally there is a decent battleship." ”

"How is the whole training, and when can I be included in the ranks?"

"Back to the prince, at most half a month, you can go to sea with weapons and equipment, but it seems that there is a war on the south side of the prince, and many people from the Central Plains have fled back."

"Luzon?"

"That's right, it's said that the Hongyi people!"

Qin Yun's eyes froze: "Everyone, our actions must be accelerated!" ”

Qin Yun thought of what William said before, and the progress of the West is not slow.
