Nanjing, near the Shibu Ya.

Xu Zhengming, who could not get close to the emperor's office, put the flying chair on the street and pedaled with his feet to attract passers-by.

According to the records of "Wu County Chronicles", this flying chair resembles a canopy chair. "There is a mechanism underneath, and the teeth are misaligned", that is, it is driven by gears. "In the chair, hit the board with two legs, go up and down, and turn the wind whirlwind", that is, use the foot pedal to drive the gear, and then let the propeller rotate and take off.

Under the onlookers of the people of Nanjing, I saw the propeller rotating rapidly, and the flat ground scraped a big fan to raise dust.

Even people with chairs, they actually flew.

"What a strange thing!"

"Fly higher, fly to the roof!"

"This place is too close to the royal family, if you fly higher, I am afraid that it will fall into Your Majesty's courtyard."

"Oh, it's falling!"

Xu Zhengming got up with a disgraced face, the skin of his right hand was bruised, and the pants at his knees were torn. He patted the dust on his palms and said in a lame official language: "Ladies and gentlemen of Nanjing, the contemptible Xu Zhengming, have come to present a flying chair to His Majesty. I had no choice but to see Your Majesty, so I offered treasures to the neighbors first. If you like it, give a few. To tell you the truth, the contemptible people are exhausted, and tonight's residence has not yet been settled. ”

"Fly again!" There was a heckling.

Xu Zhengming smiled: "Okay, fly for the neighbors again." ”

His flying chair has been improved to fly more than two feet high, that is, almost a meter. Also, there are small propellers in the tail section, which can be pushed forward and even steered.

"Up and down, turning the wind and whirling", the top is a large propeller, and the bottom is a small propeller.

There were more and more onlookers, and even the patrol police came, standing on the side of the road to watch the strangeness.

Unfortunately, this thing is too strenuous and you have to pedal like crazy. Stepping on his feet more slowly, the flying chair immediately fell down, falling down every time, and never landing smoothly.

Seeing the flying chair fall to the ground, the patrol officer immediately stepped forward and scolded: "In the streets here, don't juggle as a show, let alone gather crowds to make noise." Get out of here or you'll be fined! ”

Xu Zhengming hurriedly got up and said with his hands flattering: "This errand official, the grass people want to meet Your Majesty, so they came from Suzhou to offer this thing." ”

"If you want to see your majesty, send a letter to the big mailbox over there, and write down what is the matter," said the patrolman, "and if your majesty wishes to see you, send someone to summon you." ”

Xu Zhengming said: "It's been a few days since I surrendered, and there has been no news at all. ”

The patrolman smiled: "That's why Your Majesty doesn't want to see you." ”

When the mailbox was first set up in Nanjing, the people felt fresh, and they also wrote letters to them for trivial things.

Gradually, they found that the emperor didn't care about trivial matters, and he didn't bother to write letters after a long time.

Nowadays, most of the letters written to the emperor are submitted by private scholars, and the content is nothing more than two kinds: one is to make suggestions and put forward their own political opinions, hoping to win the favor of the emperor; One is poetry and essays, wanting to impress the emperor with his own literary talents.

There is a guy who writes a letter a day, and his name is familiar with Zhao Han.

Zhao Han directly asked people to post a notice next to the mailbox: "Gossip articles, no letters." If there is a repeat offense, none of the children and grandchildren will be officials! ”

At the urging of the patrol police, Xu Zhengming and his son carried the flying chair and wanted to leave.

saw a sturdy female official coming on horseback, shouting along the way: "Who is Xu Zhengming?" Who is Xu Zhengming? ”

"I am, I am!" Xu Zhengming hurriedly waved his hand.

The female officer reprimanded: "Why can't the inn find you? It's hard for me to find it, and my voice is hoarse. ”

Xu Zhengming said with a smile: "It's been half a month since I came down to Nanjing, and the entanglement is exhausted, and the inn guys have used sticks to drive people away." ”

The lady said, "Come with me, and take your belongings with you." ”

The father and son carried the flying chair and left excitedly.

He heard that the emperor liked strange things, so he ventured to Nanjing.

Zhao Han was in Liu Rushi's courtyard, and Liu Ru was walking and singing in the shade of a tree with a big belly. Li Xiangjun, who is a female official, sits next to her and plays the pipa accompaniment.

"Yan Nanzheng, the west wind is blowing urgently, and Hu Tian is empty. The sound book is difficult, the situation is thousands of miles fishy, and who visits the red face and the thin life? There is a lonely life of Wusun in the west, and there is a deserted tomb with smoke and green grass......"

This is a loose song in Liang Chenyu's "Jiangdong White Ramie", the content is to rely on the ancient Luntai battlefield thoughts, and the style of the song is desolate and magnificent.

Sanqu is different from opera.

Opera can be understood as Chinese opera, and sanqu is a popular song of the Ming Dynasty, which is still very good to listen to.

After singing a song, a female official came to report: "Your Majesty, Xu Zhengming brought it." ”

"Let him in." Zhao Han said.

The moment he saw the flying chair, Zhao Han couldn't help but laugh, this is a helicopter with only seats and propellers.

"Grass Folk ......"

Zhao Han stopped: "You don't need to kneel, I'll take a look when I carry it over." ”

The flying chair moved to Zhao Han, he squatted down regardless of the image, turned the pedal with his hand, and the two propellers really turned.

Moreover, it is an all-wooden structure, and even the gears are made of some kind of hardwood, and a lot of sesame oil is applied between the gears for lubrication.

The whole "helicopter", without a single nail.

Black technology!

Zhao Han stood up: "You fly and try." ”

Xu Zhengming sat in the flying chair and stepped on the pedal again. In front of the emperor, he was particularly powerful, and he actually flew more than a meter high, flew forward more than five meters away, and then ...... Crash from exhaustion.

This time it flew too high and broke the blades of the propeller directly.

"Hahaha!"

Liu Ru and Li Xiangjun were both amused, and at the same time surprised by this thing.

Xu Zhengming's son hurriedly ran to help him up, and the father and son knelt on the ground. Xu Zhengming explained: "Your Majesty, the grass people can be improved, and they will definitely be able to fly over the mountains and rivers in the future!" ”

Zhao Han said: "Get up, sit down and talk." ”

"Thank you, Your Majesty!"

The father and son hurriedly stood up and thanked the female official who moved the chair.

Zhao Han asked, "Are you a carpenter?" ”

Xu Zhengming said: "Exactly. ”

Zhao Han asked again: "How is your livelihood?" ”

Xu Zhengming said: "Thanks to Your Majesty's blessing, after losing the craftsman status, you don't have to serve the government anymore." I do some carpentry work on weekdays, but I don't have to worry about food and clothing. Even the money earned is used to make strange things, and sometimes the family will run out of food and go hungry. ”

"How long have you been doing this?" Zhao Han asked.

Xu Zhengming said: "For more than ten years, I couldn't fly at first, and then I fell down as soon as I got off the ground. Your Majesty, as long as the grass people do it for another ten years, they will be able to fly higher than the city wall. When the time comes, hundreds of flying chairs can be built for His Majesty, and they will fly straight over the city tower when the city is attacked. ”

Zhao Han thought of the picture of the Datong sergeant attacking the city in a helicopter...... The picture is too beautiful to look at.

Zhao Han asked, "Do you have a table word?" ”

Xu Zhengming said with a smile: "The grass people are just carpenters, although they have read books for a few days, where can they take the table characters?" ”

Zhao Han said: "Only the wood is correct from the rope, and the wood is burned for fire." You are a carpenter, it is better to take the word wood. ”

"Thank you, Your Majesty!" Xu Zhengming was overjoyed and jumped up from his chair and knelt down to thank him.

"Get up," Zhao Han said, "This flying chair is put aside for the time being, there is no need to go to the sky as soon as you come, you can start from the ground." You're going to do a good job with your pedals, so you might as well make a car that you can stare at. ”

"Car?" Xu Zhengming looked confused.

Zhao Han asked the female officer to take a pen and paper, drew a bicycle, and said: "People can sit on it and step on the pedal to move forward." ”

Xu Zhengming asked, "Don't you fall?" Why don't you make four wheels? ”

Zhao Han smiled: "If you ride fast, you won't fall, you can do three wheels or four wheels." ”

Regardless of how many wheels there are, a bicycle without a chain is very difficult to pedal. It was all front-wheel drive, with large front wheels and small rear wheels, and it was bumpy due to the lack of pneumatic tires.

Zhao Han asked Xu Zhengming to do a bicycle purely to exercise.

Zhao Han said: "Take my edict, go to the Qintian Academy to find Fang Yizhi, and follow him to learn mathematics and physics." ”

Xu Zhengming said: "Your Majesty, the Mathematics Grass People Association." ”

"Do you know math?" Zhao Han said with a smile.

Xu Zhengming said: "Caomin's youngest son is also reading, and his math textbook, Caomin took it and learned it by himself. It's not very difficult, as long as you memorize the numbers of the feudal kingdom, many things are the same as arithmetic. ”

Zhao Han was even more satisfied, and said: "Then I will give you an errand, and while following Fang Yizhi to learn physics, he will improve the existing spinning machines and looms." It is better to make a large machine, and you can spin a lot of yarn and weave a lot of cloth at once! When you have finished the machine, we will apply for a patent for you. The silver earned from patents will be divided into seventy percent by Qin Tianjian and thirty percent by yourself. ”

This is not an unfair contract, because the cost of research and development to improve the loom is provided by official grants.

"Yes!" Xu Zhengming learned the tone on the stage.

This cargo still wants to continue to research helicopters, but the money earned is not enough to make ends meet. So he came to see the emperor and wanted to get some silver to live.

Now it's even better, I have an errand in Qintianyuan, and I can make money while tinkering with airplanes.

In addition, under the pretext of improving looms, it is possible to use good wood "leftovers" for free.

With the introduction of water-powered spinning machines in Jiangxi, the spinning speed cannot keep up with the spinning speed. As a result, after a few years, the spinning machine has also improved, but the spinning efficiency has only increased by about 20%.

Zhao Han also doesn't understand textile machinery, and now that he has caught someone who can make a helicopter, of course he has to throw it to do some serious work.

In an era when the power system cannot follow up, the development of helicopters is indeed a "plaything"!

If Xu Zhengming continues to do it, if he can really fly a few feet high one day, then sooner or later he will be thrown to death.

After this person left, another female official came to report: "Your Majesty, Hong Chengchou and other cadres have been brought to Nanjing." ”

"Let's send it to the mines." Zhao Han was too lazy to see these traitors.

There are a bunch of things in Shandong, Hong Chengchou and Zuo Liangyu are almost forgotten. It wasn't until Fei Ruhe was ordered to move that he suddenly remembered that there were still a bunch of high-ranking prisoners, so he hurriedly sent them to the border of Jiangsu for isolation, and then took a boat all the way to Nanjing.

Wouldn't it be cheap to kill Hong Chengchou?

Zhao Han didn't like to engage in Ling Chi, and he felt uncomfortable when he slashed it. Then send it to mining, be a working people, and live for a few years depends on the creation of traitors.
