The Great Grandson of the Tang Dynasty: The beginning of the slaughter of General Tiance's mans

Chapter 279 Hehe... Your Majesty, I have an unkind favor.

After some advice from Wei Zheng, Li Chengdao became diligent again.

During this period, he was indeed a little relaxed and neglected to deal with state affairs, so it was inevitable that Wei Zheng would give him advice like that.

The only person who gave him some headaches was Huyanrena. Although Huyanrena agreed to send the two mastiffs out of the palace at the time, it was inevitable that she would not let go.

Therefore, after the incident, she was angry and ignored Li Chengdao for a long time.

Although Li Chengdao was helpless about this, he had nothing to say. After all, he was in the wrong and this matter happened because of him.

But his leisure time hobby of walking dogs disappeared, so Li Chengdao began to think about making something of his own.

"Last time I heard Jia Xu and others say that the traffic in Chang'an City is very congested in the morning and evening. How about building a new means of transportation to improve it?"

Li Chengdao had an idea and couldn't help thinking.

As the Tang Dynasty grew stronger, Chang'an, the capital, became more and more prosperous, and the number of foreigners gradually increased, causing traffic congestion.

Jia Xu and the others often delayed their time to go to court because of this, and sometimes they would walk directly to the palace on foot in a hurry, which was extremely inconvenient.

It would undoubtedly be great if we could come up with a way to change this situation.

"First of all, exclude motor vehicles. Those things cannot be built at all. In this case, the only choice is bicycles."

Li Chengdao thought about it and suddenly made a decision in his heart.

I am confident that the structure of the car is simple, and with the current technical level of the Metallurgical and Manufacturing Bureau, it is fully capable of building it.

After making up his mind, Li Chengdao took some pieces of straw paper and drew several structural diagrams of bicycles on them. He then gave them to Gao Huai and asked him to take them to the Smelting Bureau and let the craftsmen of the Smelting Bureau try it. Created.

……

In the Smelting Bureau, Xu Mo and other craftsmen frowned around the sketch of the bicycle structure sent by Li Chengdao.

"What is this? Why have I never seen it before? It's so strange."

One of the craftsmen frowned.

Gao Huai smiled slightly when he heard this and replied: "This is a vehicle invented by your Majesty, called a bicycle. Your Majesty ordered the Manufacturing Bureau to build it within ten days without any mistakes."

With detailed structural sketches, it is not difficult to build a bicycle in ten days. Even for the skilled craftsmen in the Manufacturing Bureau, less than seven days is enough.

It's just that they don't understand what kind of bicycle this is.

"There are only two wheels at the front and rear, so how can it stand?"

"Why is there no place for the horse on this bicycle?"

"Is this also called a car?"

……

The craftsmen all said that they did not understand the structure and principle of the bicycle designed by Li Chengdao.

In the end, Xu Mo closed the coffin and concluded: "Since His Majesty asked us to build it, then His Majesty's reasoning is natural. Let's just make it and get ready to start work! We will try to build this bicycle within five days!"

"Yes!"

Xu Mo is quite prestigious in the Metallurgical Bureau. After he gave the order, the entire Metallurgical Bureau began to get busy.

……

When I say five days, it really only took five days.

With the concerted efforts of the craftsmen of the entire Smelting Bureau, within five days, they built the bicycle according to the sketch given by Li Chengdao, and then Xu Mo personally took the people to the palace and handed it over to Li Chengdao.

Royal study.

"Your Majesty, Xu Mo, the supervisor of the Manufacturing Bureau, is here to see you. They have already finished the bicycle you asked the Manufacturing Bureau to build."

Gao Huai walked into the imperial study and reported to Li Chengdao.

"So fast?" Li Chengdao's eyes lit up when he heard this, and then he put down the brush in his hand.

Gao Huai's words attracted the attention of other ministers in the imperial study. Jia Xu couldn't help but ask: "Your Majesty, what is a bicycle?"

Even Jia Xu, who has always been well-informed and resourceful, asked this, let alone other ministers.

All the ministers looked at Li Chengdao with curious eyes.

"You will know when you come and take a look."

Li Chengdao said with a smile, walked out from behind Long'an and walked towards the door.

After Jia Xu and others looked at each other, they finally could not suppress their curiosity. They put down the ink pens and memorials in their hands and followed Li Chengdao out of the imperial study.

In the yard outside the imperial study, Xu Mo was waiting with two craftsmen, and there was a strange-looking thing with two wheels beside him.

It's the bike!
"You built the bicycle in just five days. Xu Qing, you really surprised me."

Li Chengdao smiled and praised Xu Mo.

Xu Mo smiled slightly, cupped his hands and said: "The Metallurgical Manufacturing Bureau is a technical research institute built with great effort by Your Majesty. It has gathered many disciples of our Mo family and skilled craftsmen from all over the Tang Dynasty. If we can even build the things that Your Majesty gave us the blueprints for, then Slow down, that Smelting Bureau is too useless."

There was a hint of pride in his words.

Li Chengdao nodded, and then looked at the bicycle produced by the Metallurgical Manufacturing Bureau.

The entire body is made of light iron, and the weight is acceptable. Fine parts such as bearings, gears and chains can be seen to be handmade.

Things like gear chains have actually been recorded in the Mohist books of the Mohist family. This is something Li Chengdao only learned about after reading the Mohist books.

Mohist books are divided into academic and technical categories. The academic type is very simple, which is to explain Mohist philosophy and knowledge.

As the name suggests, the craft category is a collection of Mohist inventions and ingenious craftsmanship, which is similar to Lu Ban Shu.

However, the latter was not passed down to later generations and was lost with the decline of the Mohist family. If Li Chengdao had not paid attention to the Mohist family again in this life, he might not have had the chance to meet him.

Xu Mo and the others also made some improvements to some details of the bicycle, such as wrapping the seat and grips with cow leather, and using two thick pieces of wood as the braking device. In short, all the details are in place.

This is a fully qualified bike.

After Li Chengdao looked at it for a while, he rode up directly, and then rode skillfully in the yard, spinning around and around.

"This...can really move?"

One of the craftsmen following Xu Mo was surprised. Although they tried to ride it after making it, no one succeeded.

Jia Xu and other ministers were even more shocked. Their interest was completely piqued, even Wei Zheng was no exception.

"If I have this bicycle, I won't have to worry about traffic jams when I go to court."

Fang Xuanling praised sincerely, looking at Li Chengdao's bicycle with envy in his eyes.

"The skills of the Smelting Bureau cannot be underestimated."

Wei Zheng touched his beard and sighed.

Li Chengdao stopped after riding a circle. He was very satisfied with the bicycle. He smiled at Xu Mo and said, "Not bad, very qualified!"

But as soon as he stopped, Jia Xu and his ministers surrounded him.

"Your Majesty, hehe... I have a heartfelt request."

Jia Xu rubbed his hands and looked at Li Chengdao, smiling maliciously.

"I also have a merciless request."

The other ministers also rubbed their hands and laughed.

Li Chengdao: "..."
